Description

METHOD, SYSTEM AND COMPUTER PROGRAM FOR MANAGING DELIVERY OF
ONLINE CONTENT

FIELD OF INVENTION

The present invention relates to the electronic identification of sought-after data objects in an electronic media environment based on user determined selection criteria. The present invention relates more particularly to online content delivery systems based on likely interest to a user.
BACKGROUND

Information networks are growing at a tremendous pace and the amount of electronic media, such as on-line information sources, can provide an overwhelming amount of information to users and publishers. Users of the electronic media environment sometimes have difficulty in finding relevant information and content providers often have problems delivering information to the user that is of interest to them.

Information overload may occur as both the user sifts through a sometimes excessive amount of information to find desired items. Similarly, publishers may be required to spend significant efforts in presenting information that may be of interest to a user before providing information that is actually of interest to the user. For example, the user and the publisher may either fail to access the sought-after data objects because they are not easily identified or expend a significant amount of time and energy to perform an extensive search of relevant data objects such as news articles to identify those to be of interest. Prior art web content searching techniques and technologies generally do not provide adequate means for assessing the quality of a data object (such as a news article) for possible interest to a user.

The most widely adopted method of information retrieval is based on keyword filtering where the user specifies a set of keywords or phrases which the user thinks are contained in the desired articles and an information retrieval system retrieves all objects which contain those keywords or phrases. Such retrieval methods are fast and easy to setup but may also be unreliable, as users may not think of the right keywords or phrases, may omit semantic equivalents, and may receive many spurious results when the specified keywords and phrases appear in unwanted articles in an irrelevant or an unexpected context. Thus, keyword and phrase filtering is generally unable to 1701487.2 offer the required granularity to capture ambiguous concepts or topics, and often results in inaccurate search results.

Starting in 1960's, a series of alternate approaches to information retrieval has been developed where personalization, collaborative, social, and clustering approaches have received attention.
In such systems, articles, publishers, and users are often described by a profile which is comprised of either a list of the explicit or implicit preferences, keywords, or other representations of interest. In these social and collaborative approaches to information retrieval, explicit or implicit preference information is generally collected from the user into a repository where a measure of similarity between users and articles is defined as. a function of. distance between their profiles. Such data is then used in the process of article retrieval by first constructing a profile of the request and then retrieving articles with profiles similar to the profile generated for the request.

:A social filtering system for net news is presented for example in. Maltz, A
D., "Distributed information for collaborative filtering on usenet net news", Masters Thesis, MIT. In the system described in this publication, each user can read an article and vote for or against it. The votes are then sent to a vote server where the votes are grouped together and.
shared with other vote servers. The servers aggregate all the different readers' opinions into one collective opinion. This aggregated opinion can then either be used by news-readers to filter shown articles, or if two users have approximately the same opinions for most of the articles in a group, but they have not read them all, then it is likely that the users would like the unread documents of the group too.

A number of researchers have looked at methods for selecting articles of most interest to users based on their past explicit or implicit feedback profiles: Such systems commonly provide a service, or an agent, which filters interesting documents against a recorded user profile. Active or, passive feedback, often commonly referred to as implicit or explicit responses from the user, is then recorded and future recommendations are adjusted correspondingly. If the pages do not match the user's profile they are not presented to the user.

One problem with collaborative, social, and personalization approaches is that of so-called cold start. The cold start problem means that the agent has no knowledge of the preferences of the user when it starts. It must have some time to learn what preferences the user has and during that time the information system generally does not perform very well.

1701487.2 Furthermore, in practice, only a small number of users even bother to respond to the feedback and preference requests, and conventional relevancy ratings are thus often not accurate predictions of the usefulness or the relevance of an article or object. Hence, the collaborative filtering approach may not work well if the users do not participate in the ratings process of objects or articles. A typical user prefers to minimize their time of interaction with the information system and is usually unwilling to spend extra time to provide additional feedback.
Another problem with content and similarity based approaches is so called serendipity problerims, which means that there is a problem for the user or publisher to find information of which it has no knowledge and possibly of a type that it may not have encountered previously. Such information might be filtered out by the information system since it might believe that information is not interesting.

A number of other researchers have looked at automatic generation and labelling of clusters, meme detection, and taxonomy classification of articles for the purposes of article summarization, aggregation and surfacing of 'replicated content. Such methods are often capable of consolidating a large number of sources to determine popular articles, or other forms of electronic media references across numerous sources. A group at Xerox PARC
published a paper titled "Scatter/gatherer: a cluster-based approach to browsing large article collections" at the 15 Ann. Int'l SIGIR '92, ACM 318-329; (Cutting et al. 1992). In this method, a collection of articles is scattered into a small number of clusters, the user then chooses one or more of these clusters based on short summaries of the cluster.

A major problem with automatic generation and labelling of clusters is that of establishing and maintaining a taxonomy for the clustering process. Since the, true number of clusters is not known, and differs for every user, the results may be unreliable and prior art systems of this type are often unable to successfully classify objects and articles which do not have sufficient coverage or follow-up, resulting in poor filter and classification performance.

U.S. Pat. No. 6,029,195 issued to Herz teaches a system that creates a customized electronic identification of desirable objects. The Herz system updates user profiles over time to match user's interests with desirable objects. U.S. Pat: No. 5,717,923 issued to Intel Corporation, teaches a system that requires active feedback to create a personal profile to adapt content to user's preferences.

1701487.2 Therefore, in the field.of information retrieval, what is needed is an efficient system which enables the user to effectively navigate through significant amounts of web content. There is a further need for a system, method, and computer program that enables intelligent filtering and customization of information delivery for web content that reflects users' unique tastes and interests. There is a further need for such a system, method, and computer program that is relatively unobtrusive, passive, and undemanding of the user. There is a further need for a system, method, and computer program enabling electronic identification of desirable data objects, such as news articles, that enables a user to access information of relevance and consistent with his/her level of interest without requiring the user to expend an excessive amount of time and energy.

DETAILED DESCRIPTION
Overview The present invention provides a system, method and computer program that enables delivery of, or access to, a subset of relevant online content, or online content likely to be of interest, from a larger universe of online content. Relevance or likelihood of interest of online content is assessed based on social engagement metrics. Social engagement metrics refers generally to the interaction of a plurality of users in a searchable medium to the online content in question.

The social engagement metrics may suggest, for example, how much the public at large is referring to particular online content, or what it is saying about that online content. This assists in filtering/ranking online content that is less relevant or, otherwise unappealing to a particular user, based on the notion that if online content is likely to be interest to many other users, it is also more likely to be of interest to the particular user. Conversely, if online content is being ignored by the public at large, it is more likely than not that the particular user may also ignore the online content, relative to other online content that is generating interest.

1701487.2 One aspect of the invention is that social engagement for online content is assessed relevant to social eingagement for similar content, as detailed below. For example, feedback on online content from a particular website is compared to normal feedback for content from the website, thus making it more likely, that interaction with the content is due to attributes of specific content rather than popularity of the website generally. The present invention contemplates a number of system aspects, computer program aspects, and method aspects that promote the derivation of information concerning likelihood of interest from social engagement metrics.

It should be understood that the online content may consist of audio, video, images, text, programs (such as Fla'shTm or Java'14-based programs), and any other online content in any media.

The description below provides some example embodiments involving online news articles, but it should be recognized to those skilled in the art that the present invention is easily extendable to other forms of online content.

System, Method and Computer Program The present invention relates to a system, method and computer program that is operable for a given data object to obtain social engagement data from a plurality of sources, analyze the social engagement data, and establish a social engagement score. In a further aspect of the invention, a ranking is established for the data object relative to other data objects associated with a user.
The user may then select among the ranked data objects a subset that matches his/her level of interest, allowing effective distribution and/or consurnption of online content.

One aspect of the present invention is an online content delivery system that enables selective delivery or accessing.of online content. The selection of online content occurs by operation of both passive and active feedback from users. "Active feedback" generally rcfer.s to qualitative feedback provided by users conceming online content, such as a recommendation of online content to other users, or qualitative feedback provided regarding online content such as a rating (e.g. "Thumbs Up" or "Thumbs Down" or rating on a scale). In contrast, "passive feedback"
generally refers to objective interactions between users and online content that while not providing direct qualitative feedback on online content.in the nature of active feedback, enables inferences to be made regarding the interest shown by users in the online content. Examples of 1701487.2 passive feedback include time spent viewing online content, bookmarking of online content and the like.

It should be understood that the present invention also enables filtering by the user itself through a variety of means such as by selecting the level of interest for online content, as determined by the ranking aspect of the present invention, that the user wishes to receive, and then linking this selection to operation of a filter.

One aspect of the present invention is enabling the collection of social engagement data regarding online content that is based on measurements of both active feedback and passive feedback.

One aspect of the invention is a data processing utility that enables processing of data conceming online content so as to collect and analyze the social engagement data, and then apply the results of such analysis to online content thereby enabling improved delivery or consumption of such online content. An additional aspect of such data processing utility is the ranking of the data objects or specific online content based on relevance and/or reaction thereto as established based on the social engagement metrics, and more specifically a social engagement score calculated by operation of the invention. The details of these aspects of the invention are provided below.

The present invention contemplates linking to, or incorporating, a number of possible functions for enabling a user to obtain a plurality of data objects from one or more sources. It is readily apparent to those skilled in the art that the present invention has particular utility when dealing with either a significant volume of such data objects and/or a large number of sources of data objects. The data objects may come from any number of sources of online content such as publication of an article, publication of a new website, changes to an existing website, an XML
feed (including for example the RSS or Really Simple Syndication), press release, and so on.

The present invention contemplates a number of different means for accessing the functionality described.

First, the operator of the system of the present invention provides a website that enables users to provide as input to the website infarmation identifying one or more sources of online content.
Based on the invention aspects described above, the website may provide an analysis of online content recently made available by such sources.

1701487.2 Second, associated with the website is a web area that enables users to customize a "My Feeds"
section or equivalent that provides a list of online content sources that the users will use for delivery and/or consumption of related content on an ongoing basis. The website, in this particular implementation, provides an online access utility for viewing, downloading or otherwise accessing online content based on the functionality described herein.

Third, the system of the present invention may interoperate with an application linked to the user's computer for accessing the online content, whether provided by the operator of the present invention or a third party, and wherein the system provides a subset of selected online content based on operation of the invention, for example, filtering or ranking of the selected online content by means of the filtering/ranking technology described below.

Fourth, the filtered/ranked online content could be provided as an input into a third party web service associated with the user.

It should be-understood that the present invention contemplates use of any means for analyzing online content of interest to a user. For clarity, this may include, for example, integration of aspects of the invention in an application, making same available as a web service, or both.

The present invention, in one aspect thereof, provides a "proxy" that consumes online content.on a user's behalf, and then is operable to rank and/or filter the content and enable the delivery of a subset of the online content having improved relevance or likelihood of interest characteristics.
The online delivery management system includes the data processing utility of the present invention. The present invention, in one implementation thereof, may include three utilities: a data collection utility; an analytics utility and a distribution utility. The data collection utility may be operable to search and determine the behavioural and social engagement metrics attached to the electronic information. It may have the ability to effectively prioritize and filter the. desired level of interest by assigning weights for attention and interaction to the data source in question.
The analytics utility may be operable to assign and optimize the weights through historical analysis of the data source content, past performance and trends. This utility may not require universal measurements and therefore the data may not be skewed by popularity of the site among users. The distribution utility may be operable to enable the delivery of the filtered data source to the user based on his/her specified preference.

170tas7.2 1~igure 1 illustrates a particular implementation of online content delivery system 100 used to transmit or otherwise provide access to online content in accordance with one aspect of the present invention. In accordance with one aspect of the system of the present invention, a server 103 may be configured to send and receive information via an interconnected computer network, such as the Internet 108. Server 103 may include or be linked to a data processing utility 106, which enables analysis of online content and ranking/filtering of online content as described herein.

As mentioned earlier, the present invention enables ranking/filtering of online content of a variety of types. The terms "data" or "data object" are used generically in this disclosure to refer an item of online content.

In a particular example of impleinentation of the present invention, the data processing utility 106 may be linked to a database 105, which may be employed to store various data intended for use by server 103, which may be implemented using.'a known web server 104.
Data files stored in the database 105 may include any type of information or materials in any medium that each publisher 102 may desire to disseminate electronically in addition to the social engagement data that may be collected by the data processing utility 106 used in the process of ranking/filtering online content. The web server 104, in accordance with one aspect of the invention may retrieve and process information requests related to ranking/filtering of online content from a plurality of users or third party systems linked to the system of the present invention, as described below.

Each publisher 102 =may make available a plurality of data files to server system 103 via the Internet 108 for use by users of on-line delivery system 100. This particular aspect is described more fully below.

In one aspect of the present invention, users "subscribe" to the online content delivery system 100 and therefore users of the present invention may be referred to as subscribers 101.
Subscribers 101 may access the functions of the system and computer program described from a standard electronic communication device (e.g. a personal computer, wireless handheld, or other computer operable to connect to the Internet or other interconnected network of computers).
Subscribers 101 may for example communicate with server system 103 via the Internet 108.
]70Ias7.2 -11=
In a particular implementation of the present invention, each personal electronic communication device may include a subscriber application (not shown), which may be configured to communicate with server system 103 in accordance with one aspect -of the invention. A
subscriber application may consist of an online RSS news-reader, a mobile application for retrieval of news, an aggregator or news portal, or any other computer application designed for retrieval or gathering of data. One aspect of the computer program of the invention, therefore is said subscriber application.

In another particular implementation of the present invention, publishers 102 may be news publishers who publish various news publications. Each publisher '102 who desires to make available its publications for online transmission or access may generate corresponding data files containing information regarding such publications. These data files may include audio information, video information, images. and other files corresponding to the text of news articles.
Some publishers may also desire to make available other updated information throughout the day. For example, blog publishers. may prepare several editions of their articles as certain inforrnation is updated throughout the day.

As previously described, each publisher may provide its electronic publications in the form. of data files, or associated information for identifying particular electronic publications for retrieval or access thereof, to server system 103 in the form of data files. To this end, in one particular embodiment of the invention, the data processing utility 106 may retrieve the data files in order to enable the that the online delivery management system 100 to make the electronic publications available to users, including electronic publications ' ranked/filtered in accordance with the present invention. The subscriber application of the present invention may enable the personal electronic communications device associated with subscriber 101 to be associated with the server.
system 103.

The personal electronic communication devices may communicate with server system 103 via a variety of available communication schemes. For example, personal'electronic communication devices 101 may establish communications with server system 103 by employing Transmission Control Protocol/Internet Protocol (TCP/IP) sockets, *Alternatively, the personal electronic communication devices may communicate with server system. 103 via direct network connections. 1701487.2 Figure 2 illustrates an information processing framework of the data processing utility 106 in accordance with one aspect of the invention. Data processing. utility 106 may include a data processing management utility 202, which may be operable to,control the various operations of data processing utility 106, including as particularized below.

Data processing management utility 202 may for example manage the application of one or more (n) data processing routines such as 203-a through 203-n that are embodied in data processing utility 106, for processing the flow of information retrieved by server system 103. Data processing routines 203 in accordance with one aspect of the invention may each enable the data processing utility 106 to gather social engagement data, as will be explained in more detail in relation to Figure 3.

Data processing utility 106 may also be linked to a database 105, in which data to be processed may be stored and from which it may be retrieved. Data processing utility 106 may also be linked to a database for purposes of storing the processed results in accordance with one aspect of the invention. Alternatively, the data processing utility 106 may be linked to a series of databases, with a specific database associated with the processing results for one or more data processing routines, and other specific databases associated with the processing results for other one or more data processing routines.

In one aspect of the invention, data processing management utility 202 may be operable to manage the workflow and scheduling of data processing jobs. During the first step, the data processing . management utility 202 may be operable to retrieve data objects from the database 105 to be processed and may schedule them for processing based on data processing routines 203.

In a particular aspect of the invention, the data processing management utility 202 may based on a data processing routine 203 retrieve the data objects scheduled for updates, such as, retrieval of new objects from the publisher or checks for changes in social engagement metrics, and initiate the update process. For example, the updates may be received from a local file system in the form of a data file. Alternatively, the file may be received via the Internet 108, a remote procedure call (REST, SOAP, CORBA, etc.), or any other forms of communications interface.
1701487.2 Figure 3 illustrates in a block diagram some aspects of data processing utility 106 in accordance with one aspect of the invention. The data processing utility 106 may comprise a social engagement retrieval agent 302, a score generator 303, a source profile viewer manager 304, and a data repository 305, which could be a database. Alternatively, a data storage manager (not shown) may perform the role of the data repository 305 for the purposes of storing the retrieved and processed data.

The data processing utility 106 may comprise multiple agents corresponding to the social engagement retrieval agent 302 in order to enable retrieval of social engagement data for each data object supplied by the data processing management utility 202. An agent 302 may comprise of a data retrieval module specific to the underlying communications network (for example, a HTTP client for retrieving web-pages), and an analysis module which processes the retrieved data to extract relevant content from the obtained data. During the first step of retrieving social engagement data, which is further described in Figure 4, the data processing management utility 202 may assign to each agent 302 the data objects requiring an update and the type of social engagement data to be retrieved, for example, retrieval of specific one or more of the social engagement sources 301. In one particular aspect of the invention, the data processing utility 106 is operable to analyze the data object in question, and based on such analysis, establish the particular social engagement data thatwill be sought in relation to the data object. For example, based on such analysis, the data processing management utility 202 may assign a particular. news article to an agent 302 and specify the category of social engagement sources 301 or for example particular third party sources of social engagement data or specific routines for identifying social engagement data implemented to the social engagement retrieval agent 302, which will be analyzed for the particular news article.

It should be understood that the social engagement sources 301 may vary, however, for the purposes of illustrating the present invention, the following social engagement sources 301 are discussed in the present disclosure: (1) comments, (2) bookmarks, and (3) trackbacks. It should be appreciated that any searchable interaction between users and online content from which level of interest can be inferred may qualify as a social engagement source 301 for the purposes of the present invention. "Comments" generally refers to searchable online comments being made by users associated with a data object. "Bookmarks" refers generally to searchable bookmarking of 1701487.2 a data object to a user. "Trackbacks" refers generally to linking back by users to a specific data object. Additional detail concerning social engagement sources 301 are set out below.

In one particular aspect of the invention the social engagement retrieval, agent 302 is operable to search the social engagement sources 301 to obtain social, engagement data for a particular data object, as the data processing management utility 202 may direct.

The social engagement retrieval agent 302 (or agents 302 providing this functionality) may then provide the collected social engagement data to the score generator 303, which may aggregate the retrieved data for further analysis. To compute the social engagement score for each object, score generator 303 may communicate with historical source profile 304.
Historical source profile 304 may be coupled with a data repository 305 for purposes of retrieval of past social engagement scores of data objects having a similar source, type, or description, or other common parameters. Alternatively, the historical source profile data may be provided directly by the data processing management utility 202.

Figure 4 illustrates the calculation of the social engagement score of a data object, based on the data provided by the agents 302. User engagement may be measured in accordance with various activities, such as bookmarkirig, commenting, and trackbacks. Initially, each of these activities may be identified 401. Next, the data processing management utility 202 triggers the score generator. 303 to rank the data -object described herein. The score generator, in a particular implementation of the invention, implements a ranking algorithm that enables the calculations described herein. It should be understood that the present invention contemplates use of different algorithms enabling the scoring functions described herein In one particular implementation of the score generator 303, a weighted formula is used to assign more weight to social engagement with online content that is more involved because for example it requires greater effort and the social engagement may suggest'a greater degiee of interest. For example, in the context of ranking a news article, a bookmark may be considered a relatively low-weight interaction requiring only a few seconds of effort. In this example, the score generator 303 may count access by a bookmark less than a comment or trackback that may be considered to require relatively more time, effort and involvement. In a similar fashion, comments may be assigned less weight than trackbacks since a trackback may presuppose that an individual wrote a follow-up article, and therefore may have invested more time than simply leaving a comment. Therefore, the score generator 303 may first be required to retrieve social engagement metrics 402, such as weights, that correspond to the various activities., These weights may then be used, to calculate the engagement score. The following formula is provided as an example of a weighted formula that may be used in accordance with this aspect:

,'5 Trackbacks = Technorati + Bloglines + Google + Own search engine Comments = extracted from the article Bookmarks = del.icio.us + diggs Engagement score = 0.5 * # of Trackbacks + 0.3 *# of comments + 0.2 *# of Bookmarks More generally the present invention may include the following weighted formula 403:
Data Object social engagement score = E' wS es Where ws is the weight of sources, and es is the social engagement score with respect to source s, as computed by the agent.

Next, historical records of social engagement data corresponding to= the data object may be retrieved 404 from a data repository, such as a database 105, or any other form of electronic storage. If historical data is available, the records may be retrieved for further analysis 405. If no historical data is available, then subsequent records may be checked for availability 406. These records may be checked and retrieved by the system for further analysis 407.
The use of historical data is illustrated below.

A process of outlier elimination may then be performed on the retrieved data.
A method. of cross validation such as a k-fold cross validation algorithm may be applied 408.
This procedure may allow the score generator 303 to eliminate outliers from the data and may ensure that a very high or a very low engagement score of up to k data objects in the history do not heavily skew the social engagement score of subsequent data objects. For example, all permutations of k-2 subsets may be computed. If k= 3 and the values are (1,2,3), then the subsets are as follows:

(1); (2), (3) -- total of 3 distinct subsets where k 1 1701487.2 As part of this process, the mean engagement score may be computed for each possible subset derived from the process of k-fold cross validation. Next, the minimuin mean social engagement score may be chosen as a baseline for comparison as follows:

Mean social engagement score = Minimum [Mean of each subset (n choose k)]
Where n is the number of historical records and k is the size of the sub-samples.

Finally the ratio of the data object's. social engagement score and the mean historical social engagement score may be computed 409 as follows:

Social engagement ratio = Data Object social engagement score / Mean social engagement score The derived social engagement ratio may serve as an indicator of social engagement for the data object as compared to past source performance. A ratio of 1.0 may translate into a`perfectly average' social engagement, whereas a ratio below 1.0 may translate into less than average social engagement performance and a ratio above 1Ø may .translate into a more than average social engagement performance.

The derived ratio may then be mapped with a custom, non-linear function, such as f-.4 (0,10] for purposes of rating and display to the user, in accordance with aspect of the invention. To perform this step, the following non-linear transfoimation function may be used in one aspect of the invention:

if score < 1.0 return 1 + 4*(score) else return [5 + (score -1), 101.minimum end In accordance with the above funetion, the average article may be assigned a score of 5Ø The lowest possible score for any article. m4y be 1.0, and the highest may be 10.
The guard condition on the maximum value in accordance with the score generator 303 ensures that even if the article receives 6 times more social engagement than the minimum engagement score, the score may be capped at 10Ø

1701487.2 Next, the computed social engagement score may be stored as an association with the parent data .
object 410. Then a check may be performed on whether the social engagement score of the data object is changed 411, by operation of the data processing management utility 202. If the score has been updated, the likelihood of subsequent updates may be high and, therefore, the interval for the next update may be decreased 412. Altematively, if the social engagement score remained the same since the last check, then the update interval may be increased 413. Finally, once the update interval is computed, the object may be scheduled for a subsequent update and the process may be repeated from the start 414.

In one aspect of the invention, when a subsequent update happens, the timestamp for next update may depend on the change in the social engagement score of.the data object..
If no changes have occurred since the last check, the interval since last check may be increased, such as being doubled. For example, if rio changes have occurred since the score generator's 303 first check, the 2 hour interval may be doubled to 4 hours and the next update may be set to: current time + 4 hours.

However, in one particular aspect of the present invention, if the engagement score has changed since the last check, the timestamp may be set with respect to a non-linear function having the following properties:

1) If the degree of change has changed less than a specified amount (for example, the degree of change is less than 10% of the last engagement score), the update interval may be kept the same. Hence, if the score changes only slightly since the first check, then the update timestamp may remain as: cunent time + 2 hours, in the above example.

2) If the degree of change has, changed more than a specified amount (for exatnple, the degree of change is greater than 10% of the last engagement score), the next update interval may be set with the following function: next update = current time +
0.5 *
last interval, in the above example.

Hence, in the above example, if the score has changed significantly, the timestamp for the next update may be effectively halved.

1701487.2 - Ig-As another step, in a particular implementation of the present invention; the following boundary conditions on the next update timestamp may be set as:

1) Maximum interval for next update = current time + 5 days 2) Minimum interval for next update = current time + 2 hours In one aspect of the invention, even if an article is receiving a lot of attention by the minute, the minimum interval for updates may be set to a specified amount such as 2 hours.
The update procedure of the present invention represents a trade off between scalability and real-time social engagement monitoring. Alternatively, update intervals may be reduced or extended to create the appropriate balance for user efficiency and effectiveness of finding sough-after objects.

Figure 5 illustrates activation and extraction of the social engagement score from a single source.
The agent. may be assigned a social engagement source and the query parameter string may be built to derive the required data 501. The query may then,be submitted and the response may be retrieved from the source 502. This communications process may be established by employing TCP/IP sockets. In the altemative, it may be -accomplished via a direct modem connection, or any other form of electronic communications.

In one aspect of the invention, a spider may be integrated in the system or computer program of the present invention which may for example have equivalent properties to a software agent, or a single elastic compute cloud (EC2) instance (virtual computer) in the AMAZONTM
Web Server (AWS) infrastructure. These spiders may be responsible for retrieving the required data to 20compute the social engagement score of the data objects (such as a specific article) as well as to retrieve new data objects currently tracked by the system. These spiders may be launched on-demand, depending on the current workload and . the amount of updates that need to be processed.

In a particular implementation of the present invention, each spider may dequeue an update 25 packet from the Input Simple Queue Service (SQS) queue, part of the AWS infrastructure, and may launch the update process. One aspect of the present invention may have two types of update packets, and hence twq different update procedures: .
1. Article updates check - checks if the social engagement score has changed for a 1701487.2 .

collection of articles provided in the updated packet 2. Feed updates check - checks if new stories are available for the collection of XML or RSS feeds provided in the update packet In both cases, the dequeued packet may contain a list of Universal Resouce Locators (URLs).
The spiders may then choose the appropriate update method, check new data objects or retrieve social engagement metrics, and may process the update. Once the updated data is collected, it may be aggregated into another packet, and may. be stored onto the Output SQS
queue. This process may repeat until all packets in the Input SQS queue have been processed.

In one aspect of the invention, the spiders may process updates in an asynchronous fashion, therefore, a set of discovery servers may be required to process in real-time the retrieval of data for new sought-after objects. For example, if a user comes to a website such as aiderss.com, and enters a new information source identifier (e.g. a, URL) which has not been previously analyzed, discovery servers may be used to retrieve the data in real-time: While the data is being collected, the user may be provided with a progress bar which shows what the discovery server is currently doing.

Next, the retrieved content may be analyzed by the agents 302 and the relevant content may be extracted from the response 503. Finally, a source-specific function fS -;~ x, described above, may be applied, mapping the extracted content into a numerical score that may represent the social engagement metrics for the object in question as derived from the source 504.

Figure 6 illustrates a more detailed view of the process of computation and updates of the social engagement score of a data object. The initial step of object retrieval may be from the publisher via a communications network such as the Internet 601.

Next, the agent 302 may compute the social engagement score of a data, object that may be of interest to a user. The retrieval.of past social engagement scores may then be performed 603, as previously described.

Finally, the algorithm for outlier elimination, previously described, and the social engagement ratio of the data object, as compared to past performance of the source, may be computed 604.
1701487.2 Once the ratio is computed, the score.may be persisted in a database .105, in accordance with one aspect of the invention.

Next, the data object may be stored in, the system, and periodically, the process may be repeated.
While repeating the process the social engagement score may be updated 605.
The data processing management utility 106 may be implemented in part as an update manager (not shown) that may run alongside the database 105 and may be responsible for scheduling updates, queueing packets onto the Input SQS queue and dequeueing and processing packets from the Output SQS queue.

In one aspect of the invention, a primary function of update manager may be to select the sought-after data objects to be updated. The update manager may. scan the, database 105 for entries which require an update, bundle each into appropriate update packets and store them on the SQS
queue. When an entry or feed has been selected for update it may also be marked as `processing' by setting an appropriate flag in the database, which may avoid duplicate updates: To select an entry or feed for update, the following conditions may be used:

1. Time for next update < current time 2. `processing' flag is 0 Once an update packet is stored on the Input SQS queue, the `processing' flag for each entry in the packet may be reset to 1.

Another function of the update manager, in this aspect of the invention, may be to process and persist the updated packets which may then be stored by the spiders onto Output SQS queue: To.
perform this step, the update manager may continually dequeue packets from the Output SQS
queue, and may send an update or insert query into the Database. As part of this process, the `processing' flag may be set to `2', which may mean that the entry has been updated, and the ranking score may need to be recomputed, as described previously.

Finally, the last function of the update manager may be to scan the database 105 for any entries which are marked as `processing = 2' and to recompute the updated ranking score for the entry.
Once the computation is complete, the new social engagement score, computed with the PostRankTM algorithm described above, may be persisted into the database and the processing flag may be reset to 0.

Figure 7 illustrates a particular aspect of operation of the online content delivery management system 100 wherein users may enter a unique identifier of an information source which they desire to be filtered via social engagement metrics 701. Such an identifier may be a URL for an 5' Internet resource, such as a blog, a news site, database, or any form of an online data source.
Next, the system may retrieve and gather the social engagement data about each data object generated by the data source 702. Once the engagement data is retrieved, a list of data objects and their associated social engagement scores may be preserited'to the user 703, allowing the user to quickly gauge the level of attention he/she should assign to each data object.

Next, based on the observed ranking, the user may select the desired filtering level for the data source 704. Depending on the level of interest in the subject or generating data source, the user may choose between a tradeoff of receiving more information with potentially lower social engagernent scores, or less information but with higher social engagement scores.

In one example of the invention, the user may select from among the following filters: all, good, great, best. For example, these filters may translate into the following score conditions by operation of the present invention:

= All (PostRank > 0.0) - send all articles.

= Good (PostRank >= 2.7) - only articles which are slightly above the half-median social engagement score = Great (PostRank >= 4.7) - only articles which received (almost) median social engagement, or more.

= Best (PostRank >= 6.5) - only articles which received 2.5 times, or more, of social engagement, when compared to past social engagement performance.

Next, the user preference may be saved 705 for the selected data source in a database 105.
Finally, articles may be delivered to the user in a chosen format based on the selected level of filtering 706. The data may be presented in a variety formats, such as HTML
pages, RSS feeds, email delivery, SMS messages, etc.

1701487.2 -.22-Figure 8 illustrates the data retrieval and delivery components of ranking/filtering in accordance with one aspect of the. invention. The publisher 102 may be responsible for generating the content, which may be retrieved by the server system 103, and may be processed by the data processing utility 106. Specifically, the processor 203 may provide the social engagement scores .5 203. The social engagement scores 203 for each sought-after data object may be calculated, as previously described, and the resulting object and social engagement scores may be persisted in a database 105, or another form of data storage and retrieval system. . .

Next, a user preference profile 802 may be built, as previously illustrated in Figure 7. Since there may be many subscribers to one data source, user preference profiles may be stored in a database 105 and processed iindependently by the server 803. A subscriber 101 may then retrieve the filtered data from the on-line delivery management system 100 in a preferred format, which may include HTML, RSS, XML, or any other well-structured format.

Figure 9 illustrates some of the components of the server system 903, and a detailed overview of the components of the application server 502 in accordance with one aspect of the invention. The server system 903 may comprise parahieters 901 supplied by the user, an application server 502, and a collection of output formats 903a-n. The parameters 901 may be supplied by the user when a request is made over the communications network. These may include a data source, a user id, a timestamp, preferred filtering level, and further customizations which help the user retrieved the desired view of the data. The parameters 901 may then be passed to the application server 502 which is responsible for generating the requested view of the data.

In a particular implementation of the. invention, the application server 502 may be linked to a news generator 506, which may be associated with a with a user profile 902, social engagement system 203, and database 105 components. The news generator 506. may be responsible for communicating with all other components in order to materialize the requested view of the data.
To perform this task, the news generator 506 may retrieve, via the application server 502, the user profile specified in the parameters 901, and may then Tequest all data objects from the database 105 which match the user profile and provided parameters 901. Next, the retrieved data objects may be filtered with respect to their social engagement scores; the specified social engagement preferences in the user profile 902 and/or the provided parameters 901.

1701487.2 Next, the application server 502 may convert the returned data objects into an output format 903a-n. The output formatS may vary and be specified by the parameters. An example of an output format.may include an HTML page, an RSS feed, or any other form of a well-defined data structure. Resulting data may then be returned to the user.

Social Engaizement Sources As an example of a computation of the engagement score of a sough-after object, the following sources may be used:

= Original entry (e.g. blog post or news article) comments section o The spider may download the content of the page and extract all of the.
available comments. In one aspect of the invention, it may then only save the count (number of comments) and discard all other information. In the altemative, it may retain andlor analyse these comments.

= Digg: number of times an item has been dugg (voted for) on digg.com o Users may submit stories to digg.com and other users may have a chance to vote on each story. If a story becomes popular; it may appear on the top page or in a sub-section of the web-site. In one aspect of the invention, the spider may count the number of `diggs' as a`bookmark' in the system.

= del.icio.us: number of bookmarks.

o del.icio.us is an online bookmarking system. Users can store their bookmarks and comments associated with each in the del.icio.us database. The spiders may query the del.icio.us servers to find out if the,current article has been bookmarked by anyone, and if so, how many bookmarks have been submitted for that URL.

= Google, Technorati, Bloglines, own search engine: number of trackbacks.

0 A trackback is a link back to the article. When a user writes a blog-post or publishes an online article, they may provide a link to an article they are discussing or referencing in their own publication. A nurnber of online search engines, such as 1701487.2 Google Blog Search, Technorati, IceRocket, and Bloglines track the number of cross-referencing links, and the spider may retrieve this inforrnation from the search results.
Possible asnects of the invention Large E-Commerce retailers In one particular implementation of the invention, in one aspect the technology may be applied to large e-commerce catalogs such as AMAZON online shopping.. Typically these catalogs contain thousands of items. It can.be difficult to find the- authoritative book on a subject where many have been published. Also, as new books are published on a topic such as marketing, it is diff'icult to separate the classics from the briefly trendy.

To assist the customer in making his/her selections, vendors such as AMAZON
have provided , metrics including explicit data such as product reviews, buyer statistics, product recommendations, vendor ratings, and overalf sales rankings. Furthermore, AMAZON customers can generate lists of recommended products to assist= other customers in selecting the best products. Implicit data, is also available in the form of customer wish-lists and via external (non-AMAZON) blogs which review products sold on sites such as AMAZON.

Using the ranking generator 303 coupled with topic detection methods, blog articles that review specific books may be identified. The same social engagement metrics may be applied to AMAZON's or other large retailers' customer wish-lists to determine the desirability of each item. Sentiment detection methods may. then be applied to the blog entries as well as the customer product reviews at the AMAZON site to assess, in addition to the 'star' ratings, positive, negative and neutral reviews and commentary on catalog items. Lastly the temporal qualities of each the above may be used to ascertain if the desirability is sustained, increasing or decreasing over time. This data coupled with AMAZON's or other large retailers' sales rankings and product recommendations may be used in a weighted calculation to determine the overall 25 desirability of each item in any catalog.

With the catalog classified, customers looking for the best products, for example a book on marketing high technology products may enter that topic in a search box. The query may then _.
identify a candidate set of books, ranked by desirability as calculated above.
A personal classifier may then be used to filter the candidate set removing previously purchased books. The same 1701487.2 previously purchased books can be used to fine tune the candidate set by boosting titles that have .
been purchased by others with similar interests based on past purchase history. With the collection of filters applied, an ordered list, ranked by overall desirability may be returned to the customer.

News In a particular implementation of the present invention, the technology may be applied- to classify online blogs that are published in the form of RSS.feeds. RSS makes it easy for users to centralize multiple information sources into a single RSS reader such as Google ReaderTM.
Because it is easy to subscribe to RSS feeds, users typically amass a substantial number (e.g. 20 plus) of feeds. Many online blogs publish articles frequently. Some that might be considered more mainstream blogs publish multiple articles each day. Users begin to experience information overload due to this volume and frequency and they require a better way to identify and select articles .that match their interests.

RSS feeds can be assigned a desirability index to facilitate this identification and selection of articles. Once articles are published at each blog, social engagement metrics may be gathered from Internet sites such as Digg.com, del.icio.us, Technorati, etc. to gauge reader reaction to the post. Trackbacks, further online blog articles referencing and in response to a particular article, as well as the number of comments in response to. each article may be collected. A weighted calculation may be performed to determine the desirability of each article.
The results of this calculation may then be compared to past article performance to determine if the desirability of the online blog is increasing, decreasing or stable over time.

To. facilitate the selection of articles of interest, users may be provided with a website to specify the filtering level of their RSS feeds on a grouping of, for example, All, Good, Great or Best.
This grouping may be based on the individual desirability calculation of each article. This may enable users that have a deep interest on a topic to filter Good articles which only applies the minimum level of filtering of non-desirable articles. For topics which the same user may only monitor casually, he/she may select Best which only presents the significant and thus highly desirable articles for the user's reading.

1701487.2 Typically RSS readers have only one pivot point and present online articles only in reverse chronological order. By assigning each object a desirability index value these objects can now be ordered by this ranking to allow users to read the most desirable and thus most relevant articles first.

Mobile In yet another implementation of the invention, the system of the present invention is deployed in connection with mobile devices. Even with filtered feeds, a user may still receive hundreds of RSS items/day. Sending hundreds of RSS items to a mobile device is infeasible due to both the bandwidth requirements' as well the technical limitations of many devices. A
classification system which identifies the highly desirable articles coupled with the recognition of the need for a mobile friendly delivery format will optimize the RSS reading experience on a mobile device.
Once a user has specified his/her RSS feeds in the aspect above, he/she may select the option of "Sync to Mobile" and automatically only the "Best" feeds may be directed to his/her mobile device to reduce both the network traffic and consequently carrier charges.
The user may optionally set ariy of the other levels, such as Good or Great, as the minimum that may be sent to their mobile device.

To further minimize bandwidth and to accommodate the reduced screen real estate, the mobile feed may be summarized and presented in a form similar to RSS partial feeds.
Each RSS object may have a MORE link that retrieves the full/original story content at the user's discretion.
