Description

WO 00/16207 PCT/US99/20461 Method and Apparatus for Rules-Based Storage and Retrieval of Multimedia Interactions Within a Communication Center by Inventor 5 Christopher Clemmett Macleod Beck et al. Field of the Invention The present invention is in the field of telecommunication encompassing all 10 existing sorts of interaction multimedia technology, and pertains more particularly to methods and apparatus for storing a complete record of multimedia interactions within a multimedia communication center using existing enterprise rules. 15 Cross-reference to related documents The present application is a continuation-in-part (CIP)of copending application P3314PA, which is a CIP of copending application P3313PA, both of which are incorporated herein by reference. 20 Background of the Invention In the field of telephony communication, there have been many improvements 25 in technology over the years that have contributed to more efficient use of telephone communication within hosted call-center environments. Most of these improvements involve integrating the telephones and switching systems in such call centers with computer hardware and software adapted for, among other things, better routing of telephone calls, faster delivery of telephone calls and associated information, and 30 improved service with regard to client satisfaction. Such computer-enhanced telephony is known in the art as computer-telephony integration (CTI).

WO 00/16207 PCT/US99/20461 -2 Generally speaking, CTI implementations of various design and purpose are implemented both within individual call-centers and, in some cases, at the telephone network level. For example, processors running CTI software applications may be linked to telephone switches, service control points (SCPs), and network entry points 5 within a public or private telephone network. At the call-center level, CTI-enhanced processors, data servers, transaction servers, and the like, are linked to telephone switches and, in some cases, to similar CTI hardware at the network level, often by a dedicated digital link. CTI processors and other hardware within a call-center is commonly referred to as customer premises equipment (CPE). It is the CTI processor 10 and application software is such centers that provides computer enhancement to a call center. In a CTI-enhanced call center, telephones at agent stations are connected to a central telephony switching apparatus, such as an automatic call distributor (ACD) switch or a private branch exchange (PBX). The agent stations may also be equipped 15 with computer terminals such as personal computer/video display unit's (PC/VDU's) so that agents manning such stations may have access to stored data as well as being linked to incoming callers by telephone equipment. Such stations may be interconnected through the PC/VDUs by a local area network (LAN). One or more data or transaction servers may also be connected to the LAN that interconnects agent 20 stations. The LAN is, in turn, typically connected to the CTI processor, which is connected to the call switching apparatus of the call center. When a call arrives at a call center, whether or not the call has been pre processed at an SCP, typically at least the telephone number of the calling line is made available to the receiving switch at the call center by the network provider. This 25 service is available by most networks as caller-ID information in one of several formats such as Automatic Number Identification (ANI). Typically the number called is also available through a service such as Dialed Number Identification Service (DNIS). If the call center is computer-enhanced (CTI), the phone number of the calling party may be used as a key to access additional information from a customer 30 information system (CIS) database at a server on the network that connects the agent WO 00/16207 PCT/US99/20461 -3 workstations. In this manner information pertinent to a call may be provided to an agent, often as a screen pop on the agent's PC/VDU. In recent years, advances in computer technology, telephony equipment, and infrastructure have provided many opportunities for improving telephone service in 5 publicly-switched and private telephone intelligent networks. Similarly, development of a separate information and data network known as the Internet, together with advances in computer hardware and software have led to a new multimedia telephone system known in the art by several names. In this new systemology, telephone calls are simulated by multimedia computer equipment, and data, such as audio data, is transmitted over data 10 networks as data packets. In this system the broad term used to describe such computer simulated telephony is Data Network Telephony (DNT). For purposes of nomenclature and definition, the inventors wish to distinguish clearly between what might be called conventional telephony, which is the telephone service enjoyed by nearly all citizens through local telephone companies and several long-distance 15 telephone network providers, and what has been described herein as computer-simulated telephony or data-network telephony. The conventional systems are referred to herein as Connection-Oriented Switched-Telephony (COST) systems, CTI enhanced or not. The computer-simulated, or DNT systems are familiar to those who use and understand computers and data-network systems. Perhaps the best example of DNT is 20 telephone service provided over the Internet, which will be referred to herein as Internet Protocol Network Telephony (IPNT), by far the most extensive, but still a subset of DNT. Both systems use signals transmitted over network links. In fact, connection to data networks for DNT such as IPNT is typically accomplished over local telephone lines, used to reach points in the network such as an Internet Service Provider (ISP). The definitive 25 difference is that COST telephony may be considered to be connection-oriented telephony. In the COST system, calls are placed and connected by a specific dedicated path, and the connection path is maintained over the time of the call. Bandwidth is basically assured. Other calls and data do not share a connected channel path in a COST system. A DNT system, on the other hand, is not dedicated or connection-oriented. That is, data, including 30 audio data, is prepared, sent, and received as data packets over a data-network. The data WO 00/16207 PCT/US99/20461 -4 packets share network links, and may travel by varied and variable paths. Recent improvements to available technologies associated with the transmission and reception of data packets during real-time DNT communication have enabled companies to successfully add DNT, principally IPNT, capabilities to existing 5 CTI call centers. Such improvements, as described herein and known to the inventor, _ include methods for guaranteeing available bandwidth or quality of service (QoS) for a transaction, improved mechanisms for organizing, coding, compressing, and carrying data more efficiently using less bandwidth, and methods and apparatus for intelligently replacing lost data via using voice supplementation methods and 10 enhanced buffering capabilities. In addition to Internet protocol (IPNT) calls, a DNT center may also share other forms of media with customers accessing the system through their computers. E-mails, Video mails, fax, file share, file transfer, video calls, and so forth are some of the other forms of media which may be used. This capability of handling varied 15 media leads to the term multimedia communications center. A multimedia communications center may be a combination CTI and DNT center, or may be a DNT center capable of receiving COST calls and converting them to a digital DNT format. The term communication center will replace the term call center hereinafter in this specification when referring to multimedia capabilities. 20 In typical communication centers, DNT is accomplished by Internet connection and IPNT calls. For this reason, IPNT and the Internet will be used in examples to follow. IT should be understood, however, that this usage is exemplary, and not limiting. In systems known to the inventors, incoming IPNT calls are processed and 25 routed within an IPNT-capable communication center in much the same way as COST calls are routed in a CTI-enhanced call-center, using similar or identical routing rules, waiting queues, and so on, aside from the fact that there are two separate networks involved. Communication centers having both CTI and IPNT capability utilize LAN connected agent-stations with each station having a telephony-switch-connected 30 headset or phone, and a PC connected, in most cases via LAN, to the network carrying WO 00/16207 PCT/US99/20461 -5 the IPNT calls. Therefore, in most cases, IPNT calls are routed to the agent's PC while conventional telephony calls are routed to the agent's conventional telephone or headset. Typically separate lines and equipment must be implemented for each type of call weather COST or IPNT. 5 Due in part to added costs associated with additional equipment, lines, and data ports that are needed to add IPNT capability to a CTI-enhanced call-center, companies are currently experimenting with various forms of integration between the older COST system and the newer IPNT system. For example, by enhancing data servers, interactive voice response units (IVR's), agent-connecting networks, and so 10 on, with the capability of conforming to Internet protocol, call data arriving from either network may be integrated requiring less equipment and lines to facilitate processing, storage, and transfer of data. With many new communication products supporting various media types available to businesses and customers, a communication center must add significant 15 application software to accommodate the diversity. For example, e-mail programs have differing parameters than do IP applications. IP applications are different regarding protocol than COST calls, and so on. Separate routing systems and/or software components are needed for routing e-mails, IP calls, COST calls, file sharing, etc. Agents must then be trained in the use of a variety of applications 20 supporting the different types of media. Keeping contact histories, reporting statistics, creating routing rules and the like becomes more complex as newer types of media are added to communication center capability. Additional hardware implementations such as servers, processors, etc. are generally required to aid full multimedia communication and reporting. 25 Therefore, it is desirable that interactions of all multimedia sorts be analyzed, recorded, and routed according to enterprise (business) rules in a manner that provides seamless integration between media types and application types, thereby allowing agents to respond intelligently and efficiently to customer queries and problems. One issue that continually plagues current art communication centers is an 30 inability of agents to keep track of customer interactions in an orderly fashion. For WO 00/16207 PCT/US99/20461 -6 example, if a certain customer has a service problem that he has contacted the center about, it is desired that all past queries and responses regarding the issue be known to an agent so that much information is not rehashed or may be even missed completely. Some current art systems known to the inventor support customer history 5 systems wherein a chronological interaction history regarding a certain customer is available via a database to an agent or agents of the communication center. This function is typically performed via threading the queries and replies in a chronological fashion wherein the customer has an identifying string. However, current art systems support only a few types of text media such as e-mail, fax or other text-type 10 documents. If an agent places a IP call to the customer, or perhaps, enlists another agent in dealing with the customer using an alternate media, manual intervention must be used in order to update the customer's transaction history. This presents a problem in that the agent or agents may forget to enter certain information into the system. In the event of an audit, the customers string would be incomplete and would not 15 accurately reflect actual history and status. What is clearly needed is a multimedia threading technique that automatically enters information to the customer interaction history as it happens regardless of media type, and also provides a method for retrieval and auditing. 20 Summary of the Invention In a preferred embodiment of the present invention a system for relating multimedia events in a multimedia-capable call center, and making the events 25 available to users is provided, comprising a data repository adapted to store files recording both text-based and non-text-based events involving the call center; recording systems for recording events of all text-based and non-text events experienced at the call center; a system for relating the stored files in one or more serial strings according to relational criteria; and an interactive display interface for 30 displaying identifiers of the stored files, the identifiers arranged in a serial string WO 00/16207 PCT/US99/20461 -7 according to the relational criteria. Selected events involving the call center are recorded, and a user, be selecting identifiers, may play individual ones of the stored files, thereby reviewing the recorded events. In this system the identifiers may comprise icons displayed on a computer 5 video monitor, the icons arranged in a serial string. There may further be a system for preparing text versions of non-text events, and for storing the text versions in the data repository related to the non-text versions in a manner that the text versions may be accessed by the interactive display interface. There may still further be a data extraction facility for deriving information from text files, including the text versions 10 of non-text files. Still further a facility may be provided for relating informational files to text files, and therefore to non-text files associated with text files, wherein the informational files may also be accessed by the interactive display interface along with the recorded events and text versions of recorded events. Relational criteria may include one or more of chronology, participants in an 15 event, organizational affiliation, and single issue relationship, but are not limited to these criteria. In some cases all communication events involving the call center are copied, related and stored, and in some cases a text version of every non-text event is prepared, related and stored. Events may include one or more of e-mails, video-mails, faxes, file share, file transfers, video calls, chat sessions, DNT calls, COST calls, and 20 voice mails. In another aspect of the invention a method is provided for relating multimedia events in a multimedia-capable call center, and making the events available to users, comprising steps of (a) storing both text-based and non-text-based events involving the call center in a data repository adapted to store multimedia files; (b) relating the 25 stored files in one or more serial strings according to relational criteria; and (c) providing an interactive display interface on a computer video monitor, the interface adapted for displaying identifiers of the stored files, the identifiers arranged in a serial string according to the relational criteria, wherein user, be selecting identifiers, may play individual ones of the stored files, thereby reviewing the recorded events.

WO 00/16207 PCT/US99/20461 -8 In the method, in step (c), the identifiers may comprise icons displayed on the computer video monitor, the icons arranged in a serial string. There may further be a step for preparing text versions of non-text events, and for storing the text versions in the data repository related to the non-text versions in a manner that the text versions 5 may be accessed by the interactive display interface. There may still further be a step for extracting information from text files, including the text versions of non-text files. There may be yet another step for relating informational files to text files, and therefore to non-text files associated with text files, wherein the informational files may also be accessed by the interactive display interface along with the recorded 10 events and text versions of recorded events. In the method the relational criteria may include one or more of chronology, participants in an event, organizational affiliation, and single issue relationship, although there may well be other relational criteria. In some cases, in step (a), all communication events involving the call center are copied, related and stored. Text 15 versions of every non-text event may be prepared, related and stored. Also, events may include one or more of e-mails, video-mails, faxes, file share, file transfers, video calls, chat sessions, DNT calls, COST calls, and voice mails. In the multimedia call center system and methods taught in enabling detail below, functions are provided for use by clients of and workers at a call center never 20 before available in the art, providing a multimedia call center of broad use and effectiveness.

A telephony network architecture 11 comprises an enterprise-hosted communication center 17 that 25 is linked to, in this example, both a publicly-switched telephone network (PSTN) 13, and a wide area network (WAN) 15, which may be the public Internet or other digital network, such as a company Intranet. In this particular embodiment communication center 17 handles both conventional telephone calls, which may be categorized as connection oriented 30 switched telephony (COST) calls, and data network telephony (DNT) calls, which WO 00/16207 PCT/US99/20461 - 10 may be DNT calls over a private digital network or calls according to a protocol such as the well-known Internet protocol. DNT calls are characterized in that data is transmitted as addressed data packets as opposed to dedicated connections in COST calls. As indicated, PSTN 13 may be a private rather than a public network. WAN 15 5 may be a company Intranet, the Internet, or another type of WAN known in the art. The particular method of call delivery and call center integration is not particularly relevant for the purposes of this invention. There are many ways known both to the inventor as well as known in the art. Particular issues discussed in the disclosure between the telephones and the computers might be implemented differently 10 depending on the actual system, but shall be deemed equivalent for all purposes of this invention. Incoming COST calls arrive at a network-level telephony switching apparatus 19 in network cloud 13 and are connected over trunk 23 to a central telephony switching apparatus 27 within communication center 17. From switching apparatus 15 27, calls are routed according to existing routing rules over internal wiring 56 to agents' telephones 47, 49, 51, and 53 residing at agents' workstations 31, 33, 35, and 37 respectively. Incoming DNT calls, and other communication events such as e-mail, file transfers and the like, arrive at a routing node 21 in WAN 15 and are passed on over 20 digital connection 25 to a routing server 29 within communication center 17. Once calls arrive at server 29, they may, in some embodiments, be routed directly over LAN 55 according to existing routing rules to personal computer/video display units (PC/VDU) such as PC/VDU 39, 41, 43, or 45 located at agent's workstations 31, 33, 35, and 37 respectively. 25 In this embodiment, switch-connected telephones 47-53 are also connected to PC/VDU's 39-45 via a headset to computer sound-card according to technique known to the inventor and accomplished via an I/O cable. Thus connected, agents may respond to incoming COST and DNT calls with the same headset. In the exemplary system and communication center shown, the equipment and 30 applications are adapted to provide for multimedia operation at each of the agent WO 00/16207 PCT/US99/20461 -11 stations, so the agents can interact with clients in many different ways, as are known in the multimedia arts. Computer telephony integration (CTI) enhancement is, in this embodiment, provided both at communication center 17 and in PSTN 13. For example, in PSTN 5 13, a processor 61 running instances of a CTI application known as a T-server (TS) to the inventors, and a statistics server (Stat) is connected to telephony switch 19 via CTI link 65. An intelligent peripheral 59 of the form of an interactive voice response unit (IVR) is connected to processor 61 via data connection 63. Similar CTI equipment is illustrated within communication center 17. Namely, a processor 67 running 10 instances of TS and Stat and connected to telephony switch 27 via CTI link 71, and an IVR 69 connected to processor 67 via a data connection 73, with processor 67 further connected to a local area network (LAN) 55 within communication center 17. In alternative embodiments there may also be a CTI processor 22 in WAN 15 connected to server 21 by a CTI link 24. Also in some embodiments a separate data 15 network 66 connects these CTI processors. In this way, intelligent routing may be performed at the network level with negotiation and direction from within communication center 17. It will be appreciated by those with skill in the art that the CTI enhancements, as immediately described above, may be hosted on one processor at PSTN 13 and on 20 one processor at communication center 17 without departing from the spirit and scope of the present invention. The inventor has chosen to show separate processors having separate functions for exemplary purposes only. It will also be appreciated by the skilled artisan that there may be many more or fewer than the four agent stations shown in communications center 17, and hardware and software arrangements may be 25 made is a variety of ways. Also, home agents might be connected in a variety of ways to the call center. In a preferred embodiment of the present invention, a customer-interaction network operating system, hereinafter termed (CINOS), is provided for the purpose of managing communications center 17, and optimizing and recording all agent/customer 30 interactions received at communication center 17 from networks 13 and 15. CINOS is WO 00/16207 PCT/US99/20461 - 12 unique in the fact that it is a multi-tiered object-and process-orientated system wherein logic regarding the various aspects of it's functionality is achieved via knowledge based architecture and object modeling. Various functions of CINOS, more fully described below, include capturing (recording), analyzing, routing, and, in many 5 instances, responding via automated process to customers engaged in interactions with the enterprise (company hosting the communication center). CINOS is adapted to support all planned communication mediums such as multimedia DNT applications including e-mail, video mail, file transfers, chat sessions, IP calls, and CTI COST transactions such as voice calls, voice mails, faxes, and so on. 10 Referring back to Fig. 1, CINOS utilizes various LAN-connected machines in order to perform various operations. Among these various hardware implementations are a multimedia server (MIS) 79 adapted to physically store and serve all multimedia transactions, and a customer-information-system server (CIS) 57 adapted to physically store and serve information relevant to customers such as purchase history, financial 15 status, product preferences, contact information, etc. A central server (COS) 77 acts as a host location for a CINOS manager application (noted in text balloon) which is, in effect, the parent application that controls all of the operation and functionality of the system. In addition to the above-mentioned machines hosting CINOS routines, each 20 PC/VDU such as PC/VDU 39, for example, has a CINOS-agent desktop interface or client application (not shown) adapted to interact with the parent application. Also, each machine that provides particular dedicated function to communication center 17 such as switch-connected CTI processors, IVR's, and other related equipment host instances of CINOS application-program interfaces (API's) to enable seamless 25 integration of differing parameters and/or protocols that are used with various planned application and media types utilized within communication center 17. Such programs may also co-reside or be in any combination or hosted by themselves. Additionally, for performance purposes, additional dedicated network links may exist between those servers, but essentially they are only performance boosters, and hence for clarity 30 purposes, only a simple network is shown.

WO 00/16207 PCT/US99/20461 - 13 As previously described, CINOS comprises a multi-tiered architecture. This unique architecture comprises an external media layer for interfacing with the customer or business contact, a workflow layer for making routing decisions, organizing automated responses, recording transactions, and so on, and an internal 5 media later for interfacing and presenting interactions to an agent or knowledge worker. An innovative concept associated with CINOS involves the use of tooled process models, knowledge bases, and other object models as base instruction for it's various functions. These modular conventions may be inter-bound with each other, and are easily editable providing a customizable framework that may conform to 10 virtually any existing business logic. In simple operation, and after any network level routing, COST calls and DNT calls including other media events arrive at communication center 17 to telephony switch 27, and routing server 29 respectively. Network level routing, as defined herein, includes any intelligent implementation that may be in place and aided via 15 processors 59, 61, and 22. Load balancing to multiple communication centers, and transferring customer data obtained at network-level over data-network connection 66 would be examples of such network-level routing. Once a call or other communication event registers at either switch 27 or routing server 29, CINOS immediately identifies the media type associated with the 20 call and begins it's processes depending on enterprise rules. For example, a live COST call may first be routed to IVR 69 whereby the customer can be presented with varying choices such as leaving a voice message, waiting in queue, receiving a call back, or perhaps an e-mail, and so on. Interaction by IVR 69, in this instance, will preferably be via voice recognition technique such as is known in the art, but may also 25 be via touch tone response or other known method. As previously described, the caller may elect from a number of options, such as to hold for a next available agent, select an automated response such as a fax back, or perhaps a later agent-initiated response such as an e-mail or call back. In all cases, CINOS seamlessly processes and executes the logic required to accomplish the goal of the caller in a media and 30 application-independent fashion.

WO 00/16207 PCT/US99/20461 -14 DNT events are handled much the same way as described above for live callers. For example, an IP call may be routed to a digital equivalent of an IVR for interaction or queued for a next available agent, and so on. In one embodiment, IVR 69 may be adapted to handle both COST and DNT interaction. 5 All interactions with live external media, including actual text-based events whether live or not, are recorded and stored in MIS 79 with an associated text version of the media stored as well, and becoming part of an overall threaded contact history. This is accomplished in varying ways according to existing parameters such as media type, whether the event is a live call, and so on. For example, CINOS may execute a 10 command directing IVR 69 to digitally record an incoming COST call during customer interaction and then store the voice recording of the transaction in MIS 79. A text version of the recording either created simultaneously from the voice recording via voice-to-text techniques (known in the art), or created by a live attendant via manual annotation may be sent to and stored in DB 79. An IPNT call arriving at 15 routing server 29 may be similarly recorded and stored in MIS 79 with an associated text version of the interaction stored in DB 79. E-mails, video calls, voice mails and so on are similarly handled. For example, an incoming e-mail is stored in MIS server 79 while text from the e-mail may be extracted and stored associated with the e-mail. The purpose of the text version of the event is twofold. Firstly, a complete 20 text-based transaction history of communication center 17 may be compiled and reserved for later access and audit. Secondly, an agent or knowledge worker may, in some instances, see the text version of the event at the same time that he receives routed notification of the event. In this way, an agent may begin mental preparation before taking a call. The text version of an event must be machine-readable and 25 human readable at times displayed. Interactive media-independent viewers, part of the agent's client application, may be used to disseminate information which may initially not be human readable. It is important to note here that the text-based version of an event may or may not be a complete and verbatim rendition of an actual media event. For example, an 30 e-mail may contain many documents each having many pages of text. Therefore, the WO 00/16207 PCT/US99/20461 - 15 text-based version of a particular e-mail event may simply contain the name and particulars regarding the author, a purchase order, and a list of the enclosed documents by title, and basic content or memo as well as a possible manual annotation. The attachments to the e-mail may be stored separately, and be also cross-indexed and 5 retrievable. Seeing the purchase order when the event is routed to an agent desktop tells the agent that this e-mail is important. A fax, stored originally as a bit-mapped document, may be converted to text in the system via optical recognition (OCR) technique wherein sometimes only certain content such as the authors contact information, basic intent of the fax, and perhaps 10 special numbers or codes contained in the original fax are recorded in a text version 79 , sometimes the whole text is OCR'd, while the original fax is stored in it's entirety in DB 79. Such codes or numbers that are specifically parsed from actual media may be part of a unique coding system set up by the enterprise whereby customers are directed to include such codes or numbers with their orders, service requests, and so 15 on. Parsing text messages is accomplished via a text-analyzer known to the inventor. In other non-text media types, such as video or graphics, descriptive notes may be taken via live attendant and stored in DB 79 as previously mentioned. Voice recognition technology may also be used in a case of recorded sound or video with 20 sound. All transactions regardless of media type are thus recorded and stored according to enterprise rules with at least a meaningful part of the content if not all of the content of such transactions converted to text and stored in DB 79 associated with the recording of the event. Again, the importance of the text version is that the extracted knowledge of the transaction therein is in machine-operable code, allowing 25 search and cross-referencing functions that may otherwise not be possible. After incoming events are analyzed and processed with regards to queuing, recording, storing, etc. CINOS decides the disposition paths of each event. For example, live calls in queue are routed to live agents if available, if this is the priority action in the enterprise rules. E-mails are either routed to next available agents using 30 a push technology, or simply stored in MIS server 79 where they may be retrieved by WO 00/16207 PCT/US99/20461 -16 agents after receiving notification. Recorded events such as IVR voice requests are stored in MIS server 79 where they may be retrieved by agents, and so on. By the use of routing and routing notification events, any media may be routed to an appropriate agent based on skill, or any other rule-based routing method over 5 LAN 55. Actual multimedia events may be accessed from MIS server 79 at the agent's discretion, or by rule, and text-based versions of those events stored in DB 79 may be mirrored and routed to the agent along with notification of the incoming event. Other services may be performed by CINOS such as responding to media 10 requests without agent participation via initiating automated fax responses, out-bound dialing campaigns wherein recorded information is given to a customer perhaps concerning an order placed by the customer, and so on. Networking via business or chat applications between several business partners, customers, agents, and so on, is possible wherein each entry may be stored in DB 79 as part of a discussion thread 15 including responses of another media type, perhaps initiated by a communication center agent to one of the participants during the discussion. As a general rule, full multimedia storage is done in a mass storage server, and linked by cross-indexing to the database. Depending on the business model, full text or only partial annotation is stored in the database, or a mix therof, e.g by media type. 20 In addition to supporting a wide variety of applications and protocol, CINOS is provided with the tools for building media-independent self-help wizards that are adapted for problem solving and reduction. Similarly, external and internal interaction media viewers are provided and adapted to support any media of choice. CINOS uses object modeling and linking techniques that are known in the art 25 to effect much of it's goal of presenting a seamless customer interaction with an enterprise agent or knowledge worker operating in a communication center such as center 17. For example, an interaction object model (IOM) represents a transcript of all interaction history stored in DB 79 and provides an audit trail of the state of transactions of all interactions. An interaction process model (IPM) controls how 30 events are handled within the operating system.

WO 00/16207 PCT/US99/20461 -17 An additional set of models handle how agents receive their routed media such as via traditional push model, blended push model, publish and subscribe model, or interrupt model. Prioritizing interaction events may also be accomplished through varying the push theme or scheme. For example, traditional push technology for e 5 mail means that only e-mail (media type) is being worked on by an agent. By blending the push model with a publish and subscribe model, the interrupt model is created wherein the agent may subscribe to various routed media such as answering phones, and responding to faxes, but may be interrupted for an important interaction of another media type such as e-mail and so on. In this way an agent's time may be 10 utilized according to enterprise rules within an automated environment. Outbound campaigns may be configured according to enterprise rules and media preference using a single rule-set knowledge-base. This single set of outbound tools can be used to initiate customer dialog via predictive dialing, e-mail push, automated recorded messages, and so on. 15 It will be apparent to those with skill in the art that common object modeling (COM) can be used to create virtually any type of model for any type of enterprise situation. It is the intention of the inventor to provide the applicable control codes known in the art for building process and object models and enabling the linking and interaction between the models. As previously described, it is partly the fact that 20 CINOS uses these various models and knowledge bases to achieve desired interaction that sets it above current-art systems. The inventor knows of no such network interfacing operating system that is based on the above described technology. CINOS may be implemented in a number of different topologies. For example, CINOS may be implemented as a centralized topology with one 25 communication center as shown here in Fig. 1, a distributed topology wherein a single communication center may span multiple physical locations, a segmented communication center wherein a single pool of agents services more than one company or customer base, or a wide communication network wherein a plurality of communication centers such as center 17 cooperatively service a common pool of 30 customers or a customer base. Enterprises involved in commerce such as large WO 00/16207 PCT/US99/20461 -18 financial institutions hosting many geographically separate communication centers may build their entire networking system using CINOS architecture in standardized and distributed fashion. There is no limitation to the type of enterprise that may use CINOS as it may be tooled to accommodate virtually any network architecture linked 5 to a communication center having DNT capability. It will also be apparent to one with skill in the art that CINOS routines according to various embodiments of the present invention may be included and implemented at the network level without departing from the spirit and scope of the present invention such as in processor 61, and IVR 59 in PSTN 13, or in routing node 10 21inWAN 11. Fig. 2 is a block diagram illustrating basic layers of the network operating system according to an embodiment of the present invention. As previously described with reference to Fig. 1, CINOS comprises three basic operating layers. They are an external media layer 83, a workflow layer 85, and an internal media layer 87. 15 External media layer 83 interfaces directly with the customers or business contacts or partners as illustrated via customers a and b, and business contact c. The bi directional arrows beneath each of the above mentioned participants illustrate interactive participation with CINOS on the customer side. External media layer 83 may, in one embodiment, be a multifaceted, web 20 based self-help interface providing news information and a host of other services that may be personalized by the customer. In many respects, external media layer 83 in this embodiment is similar to a web browser. Workflow layer 85 comprises 3 basic function categories beginning with a content analysis category 89 wherein textual analysis, voice analysis, IVR interaction, 25 recording and storing takes place. A next category is context resolution 91. Context resolution involves customer identification, business process binding, preparation for routing, and so on. A third category termed interaction routing 93 comprises various processes associated with the presentation of the interaction to agents, service persons, knowledge workers, business partners, customers and the like, that is, all transaction WO 00/16207 PCT/US99/20461 - 19 partners. Category 93 covers queuing, skill-based routing, automated treatment, workflow models, and so on. Internal media layer 87 comprises an agent desktop interface not shown in Fig. 1, but described in more detail below. Both external layer 83 and internal layer 87 5 contain the required tools for enabling media and application-independent interfacing _ such as previously mentioned self-help wizards, media viewers, and other controls as prescribed via enterprise rules. Internal media layer 87 provides an agent with, among other options, information about the customer or contact, information about current or historical 10 business processes, information about current interactions and their relationship to business processes, and a knowledge-base to guide the agent or knowledge worker with interaction response and workflow. An agent a, and agent b, and a knowledge worker c are shown herein interacting with the system as illustrated via bi-directional arrows. The skilled artisan will recognize these are merely examples, and there may 15 be many more such persons, and interactions in some instances may be routed to machines for response. It will be apparent to one with skill in the art that the multi-tiered architecture of CINOS such as is illustrated herein may comprise many more or differing steps or processes without departing from the spirit and scope of the present invention. 20 Fig. 3 is a flow chart illustrating basic steps performed by the interaction operating system of Fig. 2 related to completing a transaction between a customer and an agent, wherein the transaction is initiated by the customer. Similar steps may be accomplished in the opposite direction for communications initiated by an agent, as the system is bi-directional, but the present example will serve to teach the inventive 25 aspects of the system. In step 95, an incoming transaction, such as a live call, an e mail, etc., is received at the appropriate CTI switch (COST) or routing server (DNT) in a CINOS communication center such as center 17. In step 97, customer and media type are identified and interaction proceeds. All transactions, whether live calls, such as video calls, DNT calls and COST 30 calls, or text-based documents, such as e-mails, are recorded and stored in one or more WO 00/16207 PCT/US99/20461 - 20 mass storage devices handled by one or more database applications. This may be taken as server 79 of Fig. 1, although the diagram of Fig. 1 is exemplary. A principle object of the invention is to extract maximum information from every transaction for building a knowledge base that can be used for dynamic 5 management and future analysis and development. This is done primarily by data mining, which is applicable to machine-operable code, that is text. Because of the nature of the extraction, there is a difference in the way live calls and text-based media is handled. Discrimination as to the text nature of the media is made at step 99. If the 10 media chosen by the customer is already text-based, then the transaction is recorded as received (101), and a data mining application extracts important information in step 103 and stores it in the knowledge base. The distinct portions and versions of the transaction, such as the originally recorded version and any extracted data are related to one another and to other knowledge previously stored, and become part of a 15 threaded interaction history associated with an ongoing interaction and ultimately of an overall contact history. If the media chosen by the customer is determined in step 99 to be a live interaction such as a COST or IPNT call, then the existing knowledge base is accessed at step 107, and the call is routed to the best fit agent. This may, of course, be done in 20 a number of ways, such as an ADC, skill-based routing as known to the inventors, transfer to an IVR for automatic processing, and so on, as may be dictated by enterprise rules. If routing is to an agent, customer information may be retrieved from CIS server 57 (Fig. 1) and sent to the agent's PC, and appropriate scripts may be provided to guide an agent in interacting with the caller. 25 In step 109 the actual transaction is recorded as it takes place, which, in the case of live calls, may be a video or an audio recording or a combination of both. Preferably the recording is digitized. In step 111, a maximal text version is prepared from the actual transaction. The ability to do so depends to a degree on the sophistication of the system. This WO 00/16207 PCTi/US99/ZU4 -21 process may be as simple as a person adding notes for annotation or as sophisticated as a voice-to-text application preparing a full text version as the transaction transpires. In step 113 the text version is mined for data and resulting knowledge is stored in the appropriate knowledge base for future use, and added to overall record with 5 appropriate cross-referencing. It will be apparent to one with skill in the art that there will be many routines comprising various steps for performing different processes as may be determined by enterprise rules which may likewise vary depending on, among other considerations, company type, product and or service type, communication center architecture, 10 whether or not the system architecture is centralized or distributed, and so on. The embodiment taught herein is meant only as a basic example of process functionality related to CINOS processing of an incoming event. Fig. 4 is a block diagram illustrating agent-desktop function according to an embodiment of the present invention. An agent-desktop client 115, part of the CINOS 15 overall architecture, enables an agent or knowledge worker to configure and control his or her interface to the rest of the system and to external media. Client 115 may be personalized according to a particular agents parameters. A desktop interface 117 may appear and function much like a personalized web-browser containing many similar attributes related to network capabilities including full multimedia function, 20 software tool kits, linking and embedding capability, and so on. An HTML client application 119 oversees all of the network capability previously mentioned. In this embodiment for example, HTML client 119 communicates with an Internet information server 121 using HTTP protocol which is standard. Client 119, if provided minimally, may be used in conjunction with an 25 Internet browser for full multimedia function. In some embodiments, it may be maximally provided to be a fully featured client with full web browser function. For example, an agent may create and edit web forms, web pages, embed controls into such web-based forms or pages to provide certain customer interaction mechanisms in addition to having a fully functional navigation tool at his disposal.

WO 00/16207 rtIL/U /ZU401 -22 In another embodiment, Server 121 may be a server on a private network or corporate WAN instead of an Internet server. In a preferred embodiment, however, any number of servers on the Internet and/or linked to a WAN other than the Internet may communicate with client 119 as it intended to support all existing and known 5 communication protocols. A windows client 123 is provided to seamlessly integrate existing applications on the agent's PC to network applications and processes. This may be implemented via a desktop tool-kit 125 that contains all of the required controls for building, integrating and customizing the interface. 10 A business-logic layer comprises business object models 129, hereinafter termed business objects 129, representing contacts, interactions, knowledge-bases, events, routing processes, and other system routines. Integration and interaction of the various described desktop components with these logics is accomplished via common object modeling (COM) which is known in the art and available to the 15 inventor. Desktop to CTI integration is accomplished via controls provided or created with a CTI set of tools or tool kit (not shown). For example, if the enterprise desires to blend voice and e-mail, the CTI tool kit would be used to build and integrate the interface. Existing network applications such as CIS, enterprise resource planning 20 (ERP), Commerce, and the like interact with various business objects using COM and may also interact with a physical database using ODBC and SQL. Customer Interface Media Window 25 According to a preferred embodiment of the present invention, CINOS access by customers of an enhanced multimedia communication center, such as center 17 of Fig. 1, is controlled by means of a customer-facing media interface, by which customers may be identified and even categorized according to numerous criteria. In 30 some cases access may be controlled through subscription, or according to other WO 00/16207 PU1CT/US99/20461 -23 qualifying criteria such as may be deemed appropriate by the enterprise. For example, if the enterprise is an exclusive investment club, membership may be required. Categorizing criteria may include demographic information such as income level, credit history, or any other attribute that may be quantified and used to categorize a 5 customer. An enterprise-controlled access point may be defined as an interfacing window or portal created and maintained at a typical customer entry point in a network as may be known in the art. Such interfaces may take the form of a WEB-based customer interface (a WEB page), an interactive voice response (IVR) unit, a service control 10 point (SCP), or some other customer-facing system or apparatus as may be known in the art. For the purposes of this specification, an example of an enterprise-controlled WEB-form access and interface window is illustrated as an example for a preferred embodiment. The inventor deems such an interface to be most adept in offering best 15 fit media options while remaining accessible to a large customer or client base. Fig. 5 is a block diagram of a WEB-form customer interface according to an embodiment of the present invention. WEB form 133, hereinafter termed access window 133, is provided to be a part of an enterprise's WEB page which may be accessed through Internet connection and navigation, as is known in the art. Widow 20 133 is part of the CINOS software architecture described above, and represents the initiation of any customer interaction with the hosting enterprise. A WEB counter 143 is provided and records the number of visits to window 133. Window 133 is built and edited using COM codes available to the inventor and typically found in tool kits adapted for the purpose of creating interactive displays 25 on a WEB page. Such a tool kit may be located on an agent's desktop, perhaps part of an agent's HTML client such as client 119 of Fig. 4. In one embodiment, it may be part of a system administrator's tool kit. Window 133 contains interactive options directed at various categories and functions. For example, a new client section 135 contains interactive options related 30 to adding a new client to the active customer base of the enterprise. A customer WO 00/16207 PCT/US99/20U401 -24 service section 137 contains interactive options presented to existing clients needing service. A new order section 139 contains interactive options presented to existing clients wishing to do new business. Each offered interactive option is an embedded executable function having the 5 appropriate links to other system areas of CINOS such as may be relevant to the _ immediate interaction such as to services offered, routing routines, database searching, interaction recording, and so on. An innovative function of window 133 is to provide front-end control of access to the enterprise by existing and potential clients/customers. For example, as a 10 client, contact, or potential client interacts with the various media and functional options presented by the enterprise in window 133, he or she is being directed according to enterprise rules in such a way that he or she may first be qualified or not to patronize the enterprise. Secondly, the contacting person may be categorized and sorted as to type of qualified customer. Thirdly, the person contacting person may be 15 directed to pre-selected media options by the enterprise for various services offered including but not limited to routing live interactions, and so on. In a preferred embodiment of the present invention, access window 133 is fully customizable, based on customer data and enterprise rules with the focus of such customization directed toward benefiting the enterprise and ultimately the client. That 20 is, the client's options within window 133 are pre-selected and preferred by the hosting enterprise based in part on data about the client, details about the client's communication equipment and software, and enterprise rules and constraints. In some embodiments, the client may aid in customizing window 133. However, as it is desired by the enterprise to provide service in a cost-effective manner, the client will 25 be presented with options as preferred by the enterprise in most cases. To further illustrate, refer now to new client section 135. If window 133 is part of the enterprise WEB page, as is the case with this example, there will be a variety of visitors which may or may not be pre-qualified by the enterprise. Therefore, an interested party would begin (and be restricted to) taking a new client 30 survey, illustrated as one of the options in section 135. If the enterprise rules require WO 00/16207 PCT/US99/20461 -25 this as a first step, then the other options may be enabled only upon completion of the survey. By choosing new client survey, a second window may contain various survey options such as via e-mail, interactive voice recording, type and send method, or the like. 5 Information taken in the client survey is recorded and entered into a CINOS database such as DB 75 of Fig. 1. Such information may also be compared against enterprise rules or constraints, and other known information as may be available to the enterprise. Assuming the client is now recognized by the enterprise, the client's media hardware and telephony information may be recorded for future interaction purposes. 10 Such information may include the client's personal computer parameters including modem type, Internet connection type, computer platform type, type of Internet phone application installed, etc. Similarly, COST telephone parameters may be recorded, such as personal phone number, business phone number, cellular phone number, forwarding numbers, and so on. Such data will influence latter customization of his 15 personal window 133 for the particular client including the types of media that will be offered. Finally, the client may be asked to create a password for the purpose of accessing CINOS. A section 141 is provided containing a network log-in option along with download sections for obtaining permanent and or temporary software as 20 may be desired or needed, or, in some cases, required for the client to access certain services, view certain content, and so on. Section 137 presents media options for clients seeking customer service from the enterprise. These options are, in a preferred embodiment, presented in a customized or personalized fashion within the client's window 133 as was described 25 above. Therefore, each client patronizing the enterprise may access a version of window 133 that differs in look and functionality than that of another client. In this example, service section 137 contains options for e-mail, chat program, fax program, a self-help wizard, and a voice wizard. Other media types may be added or subtracted from the client's window 133 depending on any of several criteria. 30 Personalization of widow 133 takes into account client information as stored in WO 00/16207 PCT/US99/204b61 -26 CINOS database 75, service-agent media availability and preferences, and perhaps any overriding enterprise rules. Unless and until a client is identified there are typically no options presented to the client for continuing a transaction with the enterprise. 5 For an identified client, by selecting the e-mail option, the client's preferred e mail program may be activated for the purpose of sending a message to or soliciting a reply from a service agent. By selecting chat program, the client may be launched into a scheduled service seminar featuring many clients interacting with a service expert regarding a certain subject. One enterprise rule regarding section 137 may be 10 that there is no telephone or I-phone media option for customer service for a client in the absence of an ongoing project with the particular customer. In this sense an ongoing project includes any unfinished business that the client is involved in with the enterprise. Self-help wizards and voice wizards as illustrated in section 137 may be 15 offered to help a client resolve an issue without taxing further resource. Such wizards may be customized based on a client's recorded data, perhaps confirming past interactions, providing account or order status, and so on. In some embodiments, selecting an option might avail several additional options. For example, selecting chat program may avail three possible chat programs to choose from with different 20 schedules, content, and functionality attributed to each individual program. New order section 139 in this example contains various options adapted to facilitate placing orders. The options as illustrated herein include, but are not limited to, I-phone, call back, promotional models, video presentations, an on-line viewer, and an order wizard. Interaction is the same as was stated with regards to section 137. 25 For example, selecting promotional models, accesses a database containing the current promotional information and features of products which may be viewed interactively by the client using an on-line viewer offered as one of the functional options (tool). The options presented in the New Orders section may also be customized according to client identity, demographics, transaction history, and enterprise rules.

WO 00/16207 PCT/US99/20461 -27 On-line viewers may enable the client to view documents that are not supported on his computer platform. Selecting video presentation may avail several types of videos for viewing ,such that the client may choose one. If the client does not have a viewer installed on his computer which will support the offered video, perhaps 5 the on-line viewer may play the video, or the client could download a temporary viewer from section 141, etc. Selecting call back may bring up a second array of media choices made available by the enterprise for receiving a reply interaction from an agent. By providing a controlled interface window such as window 133 the enterprise 10 may control routing and interaction right from the beginning of customer contact. Through the innovative method of linking and reporting to other CINOS functions, and repositories, much real-time personaliation of window 133 according to enterprise rules and customer parameters may be made automatically. For example, if a client's history indicates a propensity toward frequent buying, an I-phone option may be 15 presented in customer service section 137 in his window 133 immediately after such a determination so that he may get direct customer service at all times. Certain media options, as described above, may be afforded a certain priority over one another regarding interaction with the enterprise. For example, a VIP client may have live interactive media choices offered in window 133 such as I-phone, call 20 back to COST phone, video phone, etc. A client known for infrequent contact or troublesome interactive history may be limited to text-based interaction such as e-mail and so on. As an integral part of CINOS functionality, window 133 acts as a portal through which existing and potential clients may be screened, categorized and routed 25 according to enterprise rules. Customer interfaces such as window 133 may be provided at various locations on a WAN such as the Internet without departing from the spirit and scope of the present invention. Such portals may exist in different geographic regions, and may be created for differing customer bases such as one for Latin America, and one for the pacific rim, and so on. Instances of CINOS routine 30 may be distributed widely over a network.

WO 00/16207 PCT/US99/20461 -28 Although the example provided herein is of a WEB form, it will be apparent to one with skill in the art that a CTI counterpart may be created for the COST telephony network. Such a case may be a CINOS enhanced IVR at an SCP or customer access point in the COST network. 5 CINOS, as previously described, optimizes customer/agent interaction in a manner which is economical and cost efficient to both the enterprise and the patronizing client. The customer interfacing window as taught herein with regards to Fig. 5 is innovative in that it is a fully customizable portal that facilities seamless integration between clients and enterprise agents according to enterprise rules. 10 Further innovation is evident in that client data is fully and seamlessly integrated with CINOS intelligence and enterprise rules regarding routing of interactions and other constraints or limitations that are programmed into the system. In effect, logic from the front end, or customer side, to the back end or agent side is linked and accessible to all appropriate CINOS routines which include applicable CTI CINOS routines. 15 The various customer interfacing logic is are explained more fully below in a series of process logic steps in a flow chart. Fig. 6 is a flow chart illustrating media-presentation and customer-interface logic steps according to an embodiment of the present invention. In step 145, a visitor registers at an enterprise's WEB page. The visitor is identified according to enterprise 20 rules in step 147. In step 148 CINOS determines the current status of the visitor after searching known client and contact data records. For example, the visitor may be a potential new client, an existing client, or an existing business contact. Although not specifically illustrated, a potential or new-business-client is not typically logically separated from a potential new-client until further process ensues in step 149 with 25 regards to qualification via survey. If the visitor wishes to be a client, he may log-in to the network system in step 159. Log-in may be automatic in the event that CINOS remembers the client's assigned password, or perhaps typing the password or other code may still be required for security reasons. At the time of log-in, window 133 is presented in personalized 30 fashion according to client data and enterprise rules in step 161. In step 163, WO 00/16207 PCT/US99/ZU461 -29 interaction between an enterprise entity and the client begins with a media type that is offered by the enterprise and selected by the client. An enterprise entity, as immediately described above, is herein defined as an agent, knowledge worker, service person, or any other live attendant, as well as any entity constituting an 5 automated response action such as an automated fax, an IVR, automated file downloads, etc. At step 148, if it is determined that the visitor is new, then a new client survey is conducted in step 149. Step 149 will determine if the new visitor is a client or business contact via the survey process. As described with reference to Fig. 6, the 10 client survey may be conducted using a variety of known techniques and media. Presuming that a new visitor qualifies as a client or business contact in step 149, he or she may be asked to create a password in order to provide access to CINOS. In step 153, the client's appropriate communication and system parameters are recorded for future reference and for use in customizing window 133. 15 At step 155, a client instance of CINOS, or perhaps another enabling application, may be presented for download by the client. In some embodiments, there may be no required software for download. Therefore, step 155 may be considered optional in this regard. In step 157, the new client may log-in to the network system and begin interaction. Because the client, in this case, is accessing 20 the system for the first time, the steps wherein he would obtain a customized window and begin interaction with an enterprise entity are not shown as intermediate configuration of media choices, product preferences, and the like, may still be required before a customized interface may be presented. In one embodiment, the client may not see a customized window until the next time he or she attempts to 25 access the network. Steps 165, 167, and 169 for an existing business contact as determined in step 148 are similar to steps 159, 161, and 163 for an existing client although the rules for interaction such as media used, personnel involved and so forth will be different. For example, in step 167 an existing business contact may be offered the option of using a WO 00/16207 PCT/US99/z20461 -30 network-collaboration program wherein I-phone, file sharing, video conferencing and the like are inherent to that one application. It will be appreciated that there are many possible logic sequences or steps that may be followed in interfacing and enabling interaction between a client and an 5 enterprise entity without departing from the spirit and scope of the present invention. Fig. 6 presents just one possible example of many. It will be apparent to one with skill in the art that the rules governing the types of media offered to clients may be based on a combination of variables such as may be decided upon by the enterprise without departing from the spirit and scope of the 10 present invention. Likewise, offered media types may be added or withheld from a client over a period of time based on such variables. Moreover, such additions or subtractions of media availability with regards to customer interface window 133 may be automated and based on calculated variables. In one embodiment, a client may add or subtract media choices if desired, 15 however, the enterprise may reserve the right not to engage such media if added by a client. In one embodiment, special application-independent media viewers such as the viewer offered in section 139 of window 133 of Fig. 5, are offered to clients and possessed by agents so that initial illegible information may be made human readable 20 regardless of the authoring application used by the agent or the client in the process of interaction. Rules-Based Storage and Threading of Multimedia Interactions 25 In a preferred embodiment of the present invention, all CINOS controlled interactions with customers or business contacts are recorded and stored in a contact history comprising a MIS database and a text database such as were described with reference to copending application P3313PA, and described above. That is, actual multimedia interactions are recorded to one database or to a section of one database 30 supporting all multimedia types used in the communication center, and text-based WO 00/16207 PCT/US99/20461 -31 versions are stored in another database or portion of the same database. All of the actual recorded transactions and text versions are related as a threaded contact history which may be separate from or part of the same database as will be further explained below. 5 Fig. 7 is an exemplary overview of a multimedia-interaction storage system _ within a communication center according to an embodiment of the present invention. A system architecture 171 is illustrated solely for the purpose of providing just one of many possible architectures in which the methods and apparatus of the invention may be practiced. Architecture 171, which in a preferred embodiment comprises both 10 conventional and DNT apparatus, is exemplary of an architecture that could facilitate CINOS according to an embodiment of the present invention such as is also the case of Fig. 1 At the heart of the storage system is a mass-storage repository 187 adapted to store multimedia interactions as well as text-based related files. Repository 187 may 15 utilize any form of digital storage technology known in the art such as Raid-Array, Optical Storage, and so on. The storage capacity of repository 187 will depend directly on it's implementation with regard to the size of the communication center and predicted amount of data that will be stored and kept by the system. In this example, repository 187 is divided logically into two sections. One 20 section, multimedia information system (MIS) 189, is responsible for housing all multimedia interactions defined as media that is not text-based such as audio, video, and graphics-based media. All multimedia interactions are stored in MIS 189 whether incoming, outgoing, or internal. A second section, herein referred to as text section 191 is responsible for all text-based interactions as well as text versions related to 25 non-text files. Sections 191 and 189 of repository 187 are analogous to MIS 79 and DB 75 of Fig. 3. Repository 187 is connected to a communication-center local area network (LAN) 195. Repository 187 is accessible via LAN 195 to authorized personnel within a communication center such as agents, knowledge workers, or the like, and may, in 30 some instances, also be made available to clients communicating with the call center.

WO 00/16207 PCT/US99/20461 -32 A network router (RTN) 175 is shown connected to LAN 195 via network connection 203. In this example, network router 175 is the first point within a communication center wherein DNT media arrives. Network router 175 is exemplary of many types of routers that may be used to route data over LAN 195. An Internet-protocol 5 network-telephony (IPNT) switch 176 is connected to network router 175 via data link as is known in the art. IPNT switch 176 further routes or distributes live IPNT calls that do not require routing to a live agent. IPNT calls that are routed to live agents are sent over connection 203 to LAN 195 where they reach agent PC/VDU's (not shown) or DNT- capable phones (not shown) as illustrated via directional arrows. 10 An object of the present invention is to record all multimedia interactions and store them in MIS 189. A further object of the present invention is to similarly record text versions of and text files related to all multimedia interactions and to store them in text-based section 191. For the purpose of the present invention, a text version of a non-text file is defined as a sufficient text rendition or description of a corresponding 15 multimedia interaction. Still another object of the present invention is to provide an innovative mechanism wherein authorized persons may access any particular block of text and if desired, call up the actual media to which the text relates. More detail regarding the order and manipulation of repository 187 is described further below. 20 Creating text-based versions of live multimedia interactions may, in some cases, be accomplished via an automated method. For example, a digital voice attendant 197 is provided and linked to IPNT switch 176. Digital voice attendant 197 may be of the form of a DNT-capable IVR or other digital voice-response mechanism as may be known in the art. Such automated attendants may interact with a voice 25 caller instead of requiring a live agent. A speech to text converter 199 is provided and linked to voice attendant 197. As digital voice attendant 197 interacts with a caller, speech to text converter 199 uses voice recognition technology to convert the audio speech to text. Such text may then be stored automatically into text section 191 and related to the also-recorded audio data.

WO 00/16207 PCT/US99/20461 -33 It will be apparent to one with skill in the art that as speech recognition technologies are further improved over their current state, which is adequate for many implementations, reliable text versions of audio transactions are not only possible but practical. Such speech to text conversions are used here only for the convenience of 5 automation wherein no live attendant is needed to transcribe such audio data. The inventor is familiar with such converters as used in the CINOS system according to a preferred embodiment. Such converters provide convenience in the practice of the present invention but are not specifically required to achieve the objects of the present invention. 10 Manual transcription may also be used to convert audio/video to text or code that may then be entered into text section 191. For example, a live attendant 201 is shown connected to LAN 195. Attendant 201, in this case, may be given the responsibility of transcribing audio files from speech to text and annotating video or graphics files for the purpose of creating text files related to the non-text data. One or 15 more live attendants such as attendant 201 may be provided for this purpose. Some media arriving at a communication center such as the one represented via architecture 171 will already be text-based and therefore require no conversion or annotation. Short e-mails, Faxes, word documents, and so on are part of this media category. An automated services system 193 is illustrated as having a direct connection 20 to section 191 of the data repository. System 193 is provided for certain text-based interactions, as described above, wherein a complete text record of the interaction may be mirrored, or otherwise created and stored into text section 191. Such automated services may include but are not limited to automated e-mail and fax systems. For example, a fax may be sent and mirrored into section 191 or, perhaps recreated using 25 an optical character recognition (OCR) technique and then entered. Physical text documents such as legal papers and the like, may be automatically scanned into text section 191 before they are sent to clients. There are many possible automated techniques for entering text files into a database. Such methods described with regards to automated services 193 are a convenience in practicing the present WO 00/16207 PCT/US99/20461 -34 invention but are not specifically required to achieve the objects of the present invention. With respect to the dual capability (COST/DNT) of architecture 171, a central telephony switch 173 is provided to be a first destination for COST calls arriving 5 from, for example, a PSTN network. Switch 173 may be a PBX, ACD, or another known type of telephony switch. Internal COST wiring 182 connects telephony switch 173 to agent's individual telephones (not shown). Switch 173 is enhanced via a processor 179 running an instance of T-server and an instance of Stat-server, which are software enhancements known to the inventor and have been previously described. 10 Such enhancements provide CTI applications, such as intelligent routing, but are not specifically required to practice the present invention. CINOS as previously described is adapted to be integrated with such software when present in a CINOS enhanced communication-center. An intelligent peripheral in the form of a COST IVR 177 is provided for the 15 purpose of interacting with callers seeking information and the like who do not require connection to a live agent. IVR technology may comprise voice response, touch tone interaction, or a combination of these technologies. IVR 177 is linked to processor 179 and also to automated services 193. An example of an IVR interaction may be the presentation to a caller of options for using an automated service such as 20 those described above, or perhaps waiting for a live agent. A CTI to DNT interface 181 is provided for the purpose of converting COST interactions to digital mode compatible with DNT so as to be adapted for digital storage and interaction according to CINOS functionality and enterprise business rules as described above. Interface 181 is not specifically required to practice the present 25 invention so long as appropriate application programming interfaces (API's) are provided for equipment that interfaces with CINOS. Bi-directional arrows illustrated between interface 181 and IVR 177 represent the ability to route interactions in either direction. COST to DNT conversion may be accomplished in IVR 177 in addition to or in place of interface 181. The connection architecture presented herein is 30 exemplary only.

WO 00/16207 PCT/US99/20461 -35 A speech to text converter 185 is provided for converting audio from the CTI side to text for entering into text section 191 as was taught with regards to converter 199 on the DNT side. Actual recorded media interactions are illustrated entering MIS 189 after text versions are rendered and entered into section 191, however, this is not 5 required. In some instances text versions of multimedia interactions may be rendered after the interaction is stored. There is no limitation regarding sequence. It is sufficient to say that converters 185 and 199 are capable of real-time conversion and entry. Server 183 shown connected to LAN 195 is adapted to host a CINOS 10 MGR.(operating system) application which provides control and organization with regard to various functions provided by the CINOS system as a whole. The storage architecture represented herein by element 171, and all it encompasses in this embodiment, is meant only to be an example architecture as may be dedicated to the storage and organization of communication-center data according to enterprise rules. 15 A unique method termed multimedia threading by the inventor is used in a preferred embodiment of the present invention for relating each multimedia interaction whether incoming to, out going from, or internal to the system, such as between an agent and a supervisor. This innovative process allows agents or other authorized personnel to access text data and ability cross-reference the data to actual 20 recorded multimedia interactions which may be displayed and played back. Fig. 8 is an illustration of a relational diagram as might be displayed on a display monitor, representing entities stored in the databases described. The blocks of Fig. 8 illustrate threaded text-blocks and their relationship to stored multimedia according to an embodiment of the present invention. Repository 187 comprises 25 section 191 and 189 as illustrated in Fig. 7. Section 191 contains text versions of interactions that are related by such as chronology, issue, participants, company affiliation, and the like. The text documents and versions of non-text files, represented in this case by icons, are shown related by serial position. For the sake of clarity regarding the innovative threading according to an embodiment of the present 30 invention, a brief description of prior art threading follows.

WO 00/16207 PUT/US99/2u461 -36 Threaded dialog as is known in prior art involves a system of strings or threads that are identified as being inherent to a single entity or subject matter wherein the dialog (questions and replies) is about that subject or about a question or subject that an entity has brought forth. A threaded dialog may be finite dialog (is closed at some 5 point) or it may be ongoing. Typically, a thread, which connects or associates the pieces of dialog, contains all of the dialog in the order that it happened such as in chronological order. Threading may be implemented based on other criteria as may be appropriate for a particular situation or by particular rules. As previously described with reference to the background section, prior art 10 threading techniques are confined to text such as with an on-line message board or the like. The inventor knows of no system that supports full multimedia interaction. The innovative implementation taught below integrates the text-based thread with stored multimedia interactions such that one may interact with the thread and access various stored media associated with the thread. 15 Referring again to Fig. 8, a customer 205 is illustrated as having two threads. They are issue I and issue II. Customer 205 has an assigned number XX-XX that identifies him or her with respect to the CINOS system. Issues I and II may comprise sales dialog, purchasing dialog, or any other type or purposed dialog as may be generic to the hosting enterprise. Customer 205 may well be a business contact, or 20 even an internal agent practicing dialog with a supervisor or the like. A series of icons 225-239 represent the type of media stored for each text block (text not shown). For example, issue I comprises first an e-mail text followed by a fax text, WEB text, and V-phone text. In this case, a time stamp or other known method may be used to insure that each text block is in order. Icons 225-239 are 25 interactive pointers or links to the actual media interactions that they represent. That is, the first block of e-mail text is associated with an interactive icon, in this case icon 225. By clicking on the icon a with a pointer device, the actual e-mail may be accessed and viewed. In an alternative aspect, not only the actual transaction may be presented to a user for review, but related files may also be listed or otherwise 30 presented for selection and review.

WO 00/16207 rIU i/u/Zoi4 -37 A logical link 207 represents cross-referencing capability between sections 191 and 189. Dialog may be threaded according to a wide variety of business rules. For example, a thread or string may represent dialog about a customer, product, agent, group of agents, group of customers, and so on. An identifier is assigned to an entity 5 and to all the communication events to or from that entity, or those in which the entity may have been involved such as a group discussion or chat. In this way all interactions may be organized and stored accordingly. In one embodiment, keyboard commands could be used to cross-reference to actual media instead of icons. In another embodiment, text versions of actual media 10 are fully viewable with the text itself appearing in interactive form whereupon a double click may call up the associated media and so on. There are many variations within the scope of the invention. Although actual recorded media interactions are, in this embodiment, stored in MIS 189, there does not have to be two separate databases (one for text and one for 15 actual media). All data may reside in one database and be sectioned in storage. For example, one click on the customer name may bring up text only, while a double click on the text brings up the associated media. In MIS 189, recorded multimedia interactions are represented by icons 241 247 and 251. For example element 241 represents all recorded Video phone 20 interactions. Element 243 represents all e-mails. Element 245 represents all recorded COST interactions. Similar associations are made with respect to elements 247 and 251 which represent WEB interactions and Video mails respectively. WEB interactions 247 may include on-line orders, requests, information forms, signed certificates, and so on. 25 Element 249 represents additional stored multimedia files dedicated to, for example, promoting the enterprises products or services. Promotional files 249 may comprise files of the form of any enterprise supported multimedia. These files may be tools that can be sent to clients upon request or perhaps periodically. Referring again to section 191, element 227 located on the thread labeled issue 30 I represents text from a fax. Because a fax is text-based and not a multimedia WO 00/16207 PC IUy u I -38 interaction, there is no corresponding media event associated with it. However, the fax is threaded into the dialog according to, in this case, chronological order. A short example of a proposed dialog concerning issue I follows. Element 225 represents an e-mail sent by customer 205 to the enterprise 5 requesting pricing information. An enterprise agent responds with a fax 227 to customer 205 containing the requested information. Customer 205 then places an on line order 229 along with a request for confirmation via video phone 231. Issue I may be closed at this point. Issue II may represent a threaded dialog concerning company service with regards to the customer order of issue I, or perhaps an agent-to 10 manufacturer dialog regarding how the order was handled with respect to issue I. In accordance with CINOS functionality as previously taught in descriptions above, data may be mined from repository 187 for the purpose of enhancing service to customer 205. Mined data may be used to affect routing of interactions, product promotions or advertisements that may be sent to customer 205. In some cases, 15 mined data may effect new dialog with a customer or business contact resulting in new thread additions. A complete contact history with interactive linking to actual recorded media enables the enterprise to resolve disputes more easily, better service the customer, and enhance profitability for the enterprise. Fig. 9 is a process flow chart illustrating logical steps taken when building a 20 threaded multimedia contact-history of communication-center interactions according to an embodiment of the present invention. Logical process steps as illustrated herein are meant to represent just one of many sequences which may be implemented when building a multimedia-threaded contact-history. Actual steps will depend on enterprise rules. In step 209, a current interaction to be recorded is identified. 25 Identifiers may include special passwords or codes for identifying the contacts involved with the interaction. The media type of the interaction is identified in step 211. If the media type is already text-based, as confirmed in step 213, then the interaction is prepared for entry into a database such as section 191 of Fig. 8. Preparation may include such automated processes as scanning, mirroring, file 30 conversions, and so on. Manual annotation via live attendants such as attendant 201 WO 00/16207 PUT/Usv99/u4o1 -39 of Fig. 7 may also be performed. In step 223, the text interaction is entered into section 191 of repository 187 and takes it's place along the associated dialog thread according to enterprise rules. If the interaction is of the form of non-text media as identified in step 211, 5 then the MIS section of repository 187, or section 189, is notified to accept the input. At step 219, the non-text interaction is recorded into section 189 of repository 187. This may occur in real time as the interaction takes place, or some point after the media interaction was recorded. In step 221, a text version of the recorded media or a text-based document 10 related to the transaction is rendered for storage into section 191 as part of the thread. In some instances, as described with reference to Fig. 7, step 221 is automated via speech to text converters and occurs at the same time or before the recorded multimedia interaction is entered into section 189. In other instances, text versions of multimedia interactions may be rendered after the recorded interaction is stored. A 15 live attendant such as attendant 201 of Fig. 7 may be assigned to parse video and or audio for applicable text. Such parsed text is entered into section 191 and takes it's place along the thread as was described above. In all cases, an identifying medium is used to assign portions of an ongoing dialog to the proper location along a thread as well as provide identification to actual 20 recorded media for cross-referencing such as may occur during a system audit or contact review. Further, the appropriate icons and or links are created and associated to entered text wherein actual multimedia may be cross-referenced in interactive fashion. Hence, the type of media may be readily identified by an auditing or reviewing agent simply by browsing the threaded text with accessibility to the 25 recorded events made by interactive method such as clicking an icon with a pointer device as was previously described. As an additional benefit all of the threaded dialog, whether text based or not, is rendered in a form that data mining may be used to create many useful relationships and to derive much useful information from the stored data.

WO 00/16207 PCT/US99/20461 - 40 It will be apparent to one with skill in the art that the order and specific function of logical steps as taught herein may vary according to the type of enterprise, existing enterprise rules, and so on. For example, instead of threaded dialogs being inherent to a specific customer with the dialog being about the customers interactions, 5 it may be specific to a particular agent with the dialog about the agents activities. Such differences in thread assignment may be incorporated into one rules-based repository. It will be apparent to one with skill in the art that CINOS may be implemented in a single communication center, or in a plurality of communication centers linked 10 via WAN without departing from the spirit and scope of the present invention. It will also be apparent to one with skill in the art that rules may be created which govern access to CINOS without departing from the spirit and scope of the present invention. For example, customers may be required to subscribe to CINOS, and may also be provided with a customer application enabling such access. In 15 another embodiment, access may be given to the general public according to established security rules governing commerce, financial transactions, and other processes. There are many existing and future implementation opportunities for an interaction operating system such as CINOS many of which have already been stated. 20 The spirit and scope of the present invention is limited only by the claim that follow.
