Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a technique for searching a plurality of databases (DBs) or updating a database in a plurality of user terminals that share the same space and have conversations with characters at the same time. In the present invention, the network is a virtual space that is shared by a plurality of user terminals and capable of bidirectional communication with each other on the spot.
[0002]
[Prior art]
  An example of an application in which a plurality of user terminals share the same space and have conversations using characters at the same time is chat. In chat and the like, various means have been devised for sharing information between users participating in a conversation to make the conversation more enjoyable and improving convenience. For example, techniques for easily exchanging files between users and automatically displaying a URL (Uniform Resource Locator) during conversation on a browser have already been proposed. In addition, so-called MUD systems that can create and manipulate objects during conversation have already been provided.
[0003]
  Furthermore, if an external DB can be called during a conversation, it is possible to know in real time who accessed the DB in what context, so that sharing of information through the conversation can be promoted and the DB can be accessed immediately. it can. Such technologies include, for example, “Collaborative Information Retrieval: Gopher from MOO” (Larry Masinter, Erik Ostrom, Proc. INET'93) and “Interactive Activation Agents Participating as a Participant” (Nishimoto, Kaku, Mase, Shingaku Technical Report TL96-7 (1996-11)).
[0004]
[Problems to be solved by the invention]
  However, in the system configuration described above, only the search of the external DB is targeted, and it is not possible to update the DB or register information. In addition, since the DB is directly accessed from the chat application, all search results including details of interaction with the DB are displayed on the screen during conversation, which disturbs the original conversation. Furthermore, it is assumed that only a single DB is searched, and a plurality of DBs are not targeted. If it is simply extended to a plurality of channels to update the database or register information, there arises an access control problem such that registered information belonging to a certain channel can be referred to by other channels. Here, the channel refers to a space shared by conversation participants.
[0005]
[Means for Solving the Problems]
  In order to solve the above problems, the present invention provides1The present invention is an information management system comprising a plurality of information terminals sharing the same network and capable of talking at the same time, and one or more first storage means storing information, wherein at least the first storage means A storage identifier indicating a location and the name of the first storage means;Keywords andAre provided with second storage means capable of storing in association with each other. At least one first information terminal of the plurality of information terminals includes a detection unit, a reading unit, and a notification unit. The detecting means is a designation of at least the first accumulating means that appears in the network,keywordAnd a predetermined utterance including a search instruction. The reading meansAnd keywordsBased on the above, the storage identifier is read from the second storage means. The notification means creates an activation identifier for searching for the first storage means based on the read storage identifier, and notifies the network of the activation identifier.
[0024]
  At least one second information terminal of the plurality of information terminals includes an access unit and an activation unit. The access means can retrieve information from the first storage means based on the activation identifier. The activation means detects the activation identifier that appears in the network, and activates retrieval of information by the access means.
[0025]
  In the second storage means, for example, a DB name that is easy for the user to remember and a pointer to the DB are stored. The first information terminal detects a predetermined message appearing on the network by the detecting means. This statement includes, for example, a DB name and a keyword. Based on this DB name, the corresponding storage identifier is read from the second storage means. Further, the notifying means accesses the first accumulating means indicated by the accumulating identifier, creates an activation identifier for searching by a keyword, and notifies the network that made the statement. The second information terminal detects an activation identifier that appears in the network, and activates retrieval of information by the access means.
[0026]
  No. of this application2The invention is such that the notifying means of the first information terminal notifies the activation source of the utterance identifier with a predetermined identification flag indicating that it is a reply to the utterance, and the second information terminal Provides an information management system further comprising access control means for determining whether or not to send the activation identifier to the access means based on the identification flag.
[0027]
  The notifying means notifies the activation identifier with an identification flag for notifying the information terminal that has made a statement that it is an activation identifier for the statement. This identification flag is a predetermined flag used in a communication protocol such as an IRC application, as described above. The IRC application or the like that has received this request notifies the activation identifier by turning on the identification flag to a network in which only the first information terminal and the second information terminal are participating, for example. Other information terminals are notified of the activation identifier as a statement that the identification flag is off in another network. Therefore, the information terminal can determine whether to access the external DB based on the identification flag, and can prevent access to unnecessary information.

[0033]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing the configuration and function of an information management system according to an embodiment of the present invention. The information management system in FIG. 1 includes an external database DB, a plurality of user terminals CC1, a channel database CDB, at least one user terminal CC2, a chat server CS, and a network NW.
[0034]
  The external DB is a normal database in which information is stored, and is read-only for general users. The chat server CS communicates with the user terminal CC using a protocol such as that indicated by REC 1459, and provides a chat service to a plurality of user terminals CC. In the channel database CDB, an information identifier indicating the storage location of information in the database DB and a keyword that briefly represents the content of the information can be stored using the channel as a key. A specific example of the information identifier is a URL. Information in the CDB can be registered, updated, deleted, and searched by using a channel as a key by a user terminal having an information identifier operation unit 8 described later. FIG. 2 is a conceptual structural diagram of information stored in the CDB. However, in addition to the information shown in FIG. 2, other information such as the update date of each entry can be stored in the CDB as needed.
[0035]
  The user terminal CC1 is connected to an external DB, and can operate a chat application and a normal DBAC application for accessing the DB. The chat application performs communication according to a normal chat protocol regardless of the operation of the DBAC application. In FIG. 1, only one user terminal CC1 is shown, but usually a plurality of user terminals are connected to the network.
[0036]
  The user terminal CC1 includes an information identifier receiving unit 3 and an input / output unit 4 including an identifier detection unit 1 and an access control unit 2 in addition to the application. The identifier detection unit 1 monitors the chat channel conversation and detects the appearance of an information identifier. The information identifier appearing in the channel includes a case where the response is an answer from the user terminal CC2 to a search instruction made by the user terminal CC1, and a case where the answer is an answer to another user terminal.
[0037]
  The access control unit 2 sends an information identifier to the DBAC application, and activates access to the information storage location indicated by the information identifier. Further, the access control unit 2 refers to the identification flag of the information identifier that appears in the conversation, and determines whether or not to send the appearing information identifier to the DBAC application. This identification flag is defined by a communication protocol of a normal chat application, and is used for identifying whether the message is a message input by a user or a message generated by a program. In this embodiment, the information identifier uttered by the information identifier operation unit 8 of the user terminal CC2 described later is used to indicate which user terminal is addressed.
[0038]
  The information identifier is usually spoken with the identification flag off, and the access control unit 2 determines not to send the information identifier to the DABC application. However, in the case of an answer to the search instruction of the user terminal CC1, it is determined that the identification flag is on and the information identifier is sent to the DBAC application. By using this identification flag, the DBAC application is activated and information is automatically read out only at the user terminal CC1 that has instructed the search. Other user terminals are simply notified of information identifiers through channels.
[0039]
  The input / output unit 4 performs input / output of conversations in the chat application, output of DB search results by the DBAC application, and the like. The user terminal CC2 can operate a chat application, and includes an information identifier operation unit 8 including a command detection unit 5, a CDB access unit 6, and an identifier transmission unit 7, and an input / output unit 9. The command detection unit 5 monitors the conversation on the channel and detects a message in a predetermined format including a specific command. In this embodiment, the commands include “search”, “register”, “delete”, and “update”. A keyword is followed by “search” and “delete”, and an information identifier and a keyword follow after “registration” and “update”. Further, the command detection unit 5 acquires the channel name in which the message has been made from the chat application and sends it to the CDB access unit 6.
[0040]
  The CDB access unit 6 acquires predetermined information according to the command detected by the command detection unit 5 and accesses the CDB. For example, when the message “search, patent” is detected in the channel “patent”, the CDB access unit acquires the channel name “patent” and the keyword “patent”, and reads the corresponding information identifier from the CDB. In the example of the CDB shown in FIG. 2, “data1” is read. The read information identifier is sent to the identifier sending unit 7. When the command “delete” is detected, the corresponding information identifier entry is deleted from the CDB in the same manner as described above. When the command “registration” or “update” is detected, the information identifier and keyword following the command are acquired and written together with the channel name in the CDB.
[0041]
  The identifier sending unit 7 requests the chat application to speak the information identifier read by the CDB access unit 6 on the channel in which the command includes the command and the identification flag is turned off. Further, the request source of the command is requested to turn on the identification flag on the one-to-one channel between the user terminals CC1 and CC2.
[0042]
  [Flow of processing in user terminal CC1]
  FIG. 3 is a flowchart showing a flow of processing performed by the information identifier receiving unit 3 in the user terminal CC1. The following process is started when the chat application is activated in the user terminal CC1. In step S <b> 1, the identifier detection unit 1 acquires a message appearing in the chat channel as a character string.
[0043]
  In step S2, it is determined whether or not the acquired character string is an information identifier. If it is an information identifier, the process proceeds to step S3. If it is not an information identifier, the process returns to step S1 again to obtain the next character string. In step S3, the access control unit 2 determines whether the identification flag of the information identifier is on. If it is on, the process proceeds to step S4. If the identification flag is off, the external DB is not accessed and the process returns to step S1.
[0044]
  In step S4, the acquired information identifier is sent from the access control unit 2 to the DBAC application. The DBAC application that has received the information identifier accesses the storage location indicated by the information identifier according to a normal operation, and displays the read information on the output unit. In step S5, it is determined whether or not the chat application has ended. If it has ended, this process ends. If the chat application has not ended, the process returns to step S1 and the process is repeated again.
[0045]
  [Flow of processing in user terminal CC2]
  FIG. 4 is a flowchart showing a flow of processing performed by the information identifier operation unit 8 in the user terminal CC2. The following processing is started when the chat application is activated in the user terminal CC2. First, in step S11, the command detection unit 5 acquires a comment appearing in a chat channel as a character string. At the same time, the name of the channel that made the statement is acquired from the chat application.
[0046]
  In step S12, the CDB access unit determines whether or not the acquired character string starts from “search” or “delete”. If it starts from “search” or “delete”, the process proceeds to step S13. Otherwise, the process proceeds to step S18 described later. In step S13, the keyword subsequent to “search” or “delete” is read from the acquired character string by the CDB access unit.
[0047]
  In step S14, the CDB access unit determines whether or not the command is “delete”. If it is “delete”, the process proceeds to step S15. If it is not “delete”, the process proceeds to step S16. In step S15, the CDB access unit searches the CDB based on the acquired keyword and channel, and deletes the corresponding entry.
[0048]
  In step S16, the CDB access unit searches the CDB based on the acquired keyword and channel, and acquires the information identifier of the corresponding entry. In step S17, the acquired information identifier is sent to the chat application by the identifier sending unit. In step S18, it is determined whether or not the character string acquired in step S11 starts with "registration" or "update". If it starts with "registration" or "update", the process proceeds to step S19. Otherwise, the process returns to step S11.
[0049]
  In step S19, predetermined information following "registration" or "update", that is, a keyword and an information identifier are read from the acquired character string. In step S20, it is determined whether or not the command is "update". If it is "update", the process proceeds to step S21. Otherwise, the process proceeds to step S22 described later. In step S21, the CDB access unit creates a new entry for the CDB, and writes the information identifier channel name and keyword.
[0050]
  In step S22, the corresponding entry is searched from the channel name and the keyword, and the information identifier of the corresponding entry is updated. In step S23, it is determined whether or not the chat application has ended. If not, the process returns to step S11 and the process is repeated again. If the chat application is finished, this process is also finished.
[0051]
  [Example of processing]
  Next, processing performed in the information management system will be specifically described by taking the case of search processing and registration processing as an example. In the following processing, it is assumed that the information illustrated in FIG. 2 is stored in the CDB.
  FIG. 5 is an explanatory diagram showing the flow of search processing. In the channel “patent”, when “search, patent” consisting of a command and a keyword is uttered from the user terminal by the user input (# 1), the user terminal CC2 receives (# 2). Since the received message starts with “search” (# 3), the CDB is searched from the keyword “patent” and the channel name “patent” following “search” (# 4), and the corresponding information identifier “data1” is acquired. (# 5). The acquired information identifier “data1” is remarked by the chat application with the identification flag turned off for the channel “patent”, and the identification flag is set for the one-to-one channel “CC1-CC2” between the user terminals CC1 and CC2. It is turned on and remarked (# 6).
[0052]
  The user terminal CC1 sends the information identifier “data1” received on the channel “CC1-CC2” to the DBAC application. As a result, reading of information stored in “data1” is started (# 9). In the user terminals participating in the channel “patent” other than the user terminals CC1 and CC2, since the identification flag is off, DBAC is not activated in the user terminals. However, it is known that it is an information identifier in the user terminal CC3, and can be sent to the DBAC application and read out by a simple instruction from the user.
[0053]
  FIG. 6 is an explanatory diagram showing the flow of registration processing. In the channel “hilab”, when the user terminal CC1 says “registration, interface, data2” as a command, a keyword, and an information identifier (# 11), the user terminal CC2 receives (# 2). Since the received message starts from “registration” (# 3), the keyword “interface” following “registration”, the information identifier “data2”, and the channel name “patent” are acquired (# 14) and written to the CDB (# 15).
[0054]
  <Second Embodiment>
  FIG. 7 is a block diagram showing the configuration and functions of the information management system according to the second embodiment of the present invention. 7 includes a plurality of external databases DB1, DB2, one or more user terminals CC3, CC4,... And a chat server CS. The external databases DB1 and DB2 are ordinary databases in which readable information is accumulated.
[0055]
  The user terminal CC3 is connected to a plurality of external databases DB1 and DB2, and can operate a chat application and a DBAC application that accesses the external DB. The chat application and the DBAC application operate independently. In addition to the above-described operation of the application, the user terminal CC3 includes an activation identifier receiving unit 13 and an input / output unit 14 including an identifier detection unit 11 and an access control unit 12.
[0056]
  The identifier detection unit 11 monitors chat conversation and detects the appearance of a DB activation identifier. The DB activation identifier is a character string composed of a predetermined command for instructing detection, a DB identifier indicating the location of the DB, and a keyword. The DBAC application is instructed to search the DB specified by the DB identifier with the specified keyword. Start up. The detected DB activation identifier is sent to the access control unit 12.
[0057]
  Based on the identification flag of the DB activation identifier received from the identifier detection unit 11, the access control unit 12 determines whether to access DB1 or DB2. If the identification flag is on, the received DB activation identifier is sent to the DBAC application. As a result, the DBAC application is activated, and a search based on the DB and the keyword specified by the DB activation identifier is started. The input / output unit 141 performs input / output of a conversation in the chat application, output of a DB search result by the DBAC application, and the like.
[0058]
  The user terminal CC4 can operate a chat application. Furthermore, the user terminal CC4 has an activation identifier operation unit 19 and an input / output unit 20 that are composed of a command detection unit 15, a DB list 16, a list reading unit 17, and an activation identifier creation unit 18. The command detection unit 15 monitors a conversation by chat and detects a specific statement. In the present embodiment example, the specific message includes a character string including a predetermined format “command, database name, keyword”. “Search” is designated as the command, and “DB1” or “DB2” is designated as the database name. The keyword is arbitrarily designated by the user. The specified database name and keyword are sent from the command detection unit 15 to the list reading unit 17.
[0059]
  In the DB list 16, a database name and a DB identifier indicating the location of the database are associated and stored. FIG. 8 shows a conceptual structural diagram of a DB list in which DB names and DB identifiers are stored. The list reading unit 17 accesses the DB list 16 based on the DB name detected by the command detection unit 15, reads the corresponding DB identifier, and sends it to the activation identifier creation unit 18 together with the keyword.
[0060]
  The activation identifier creating unit 18 creates a DB activation identifier based on the DB identifier and the keyword. The activation identifier creating unit 18 requests the chat application to speak the created DB activation identifier with the identification flag turned off on the same channel where the specific statement is made. In addition, a request is made to turn on the identification flag and speak the DB activation identifier on the one-to-one channel between the user terminals CC3 and CC4 that have made the specific statement. In the user terminal CC3 that has made a search command, access to the DB is automatically started by the DB activation identifier uttered on the chat. For other user terminals CC3, only the DB activation identifier is on the channel. To be notified.
[0061]
  [Processing flow in user terminal CC3]
  FIG. 9 is a flowchart showing a flow of processing performed by the activation identifier receiving unit 13 in the user terminal CC3. When the chat application is activated on the user terminal CC3, the following processing is started. First, in step S31, the identifier detection unit 11 acquires a message appearing on a channel as a character string.
[0062]
  In step S32, the identifier detection unit 11 determines whether or not the acquired character string is a DB activation identifier. If it is a DB activation identifier, the process proceeds to step S33. If it is not a DB activation identifier, the process returns to step S31 again to acquire the next message as a character string. In step S33, the access control unit 12 determines whether the identification flag of the DB activation identifier is on. If it is on, the process proceeds to step S34. If the identification flag is off, the external DB is not accessed and the process proceeds to step S35 described later.
[0063]
  In step S34, the access control unit 12 sends the acquired DB activation identifier to the DBAC application. The DBAC application that has received the DB activation identifier searches the database specified by the DB activation identifier using the specified keyword, reads the information, and displays it on the output unit. In step S35, it is determined whether or not the chat application has ended. If it has ended, this process ends. If the chat application has not ended, the process returns to step S31 and the process is repeated.
[0064]
  [Flow of processing in user terminal CC4]
  FIG. 10 is a flowchart showing a flow of processing performed by the activation identifier operation unit 19 in the user terminal CC4. The following processing is started when the chat application is activated in the user terminal CC4. First, in step S41, the command detection unit 15 acquires a comment appearing in the chat channel as a character string.
[0065]
  In step S42, the command detection unit 15 determines whether or not the acquired character string includes a character string having a predetermined format of “search, database name, keyword”. If included, the process proceeds to step S43. Transition. Otherwise, the process proceeds to step S46 described later. In step S 43, the command detection unit 15 reads the database name and keyword following “search” from the acquired character string, and sends these pieces of information to the list reading unit 17.
[0066]
  In step S44, the list reading unit 17 accesses the DB list 16, reads the DB identifier corresponding to the database name, and sends it to the activation identifier creating unit 18 together with the keyword. In step S45, the activation identifier creating unit 18 creates a DB activation identifier based on the DB identifier and the keyword, and sends it to the chat application.
[0067]
  In step S46, it is determined whether or not the chat application has ended. If not, the process returns to step S41 to repeat the process again. If the chat application is finished, this process is also finished.
[Example of processing]
  Next, the search process in the information management system will be specifically described with reference to the explanatory diagram of the search process shown in FIG. In the following processing, it is assumed that the information shown in FIG. 8 is accumulated in the DB list.
[0068]
  When the user terminal CC3 says “search, DB1, patent” on the channel “patent” (# 21), the user terminal CC4 receives the message (# 22). If the remark starts from “search” (# 23), the DB list is searched based on the database name “DB1” following “search” (# 24), and the DB identifier “patent-db.fujitsu.co” of DB1 is searched. .jp "is acquired (# 25).
[0069]
  Next, from the acquired DB identifier, create a DB startup identifier, “search & DB = patent-db.fujitsu.co.jp = patent”, which instructs to search DB1 with the keyword “patent” and starts the DBAC application (# 26). The created DB activation identifier is sent to the chat application, the identification flag is turned off on the channel “patent”, and the identification flag is set on the one-to-one channel “CC3-CC4” between the user terminals CC3 and CC4. It is turned on and remarked (# 27). FIG. 12 shows a screen example of the channel “patent” at this time.
[0070]
  The user terminal CC3 sends the DB activation identifier received on the channel “CC3-CC4” to the DBAC application (# 28). As a result, the DBAC application is activated to start searching for DB1 (# 29), and the corresponding information is displayed on the screen of the user terminal CC3 (# 30).
<Another embodiment>
  (A) In the first embodiment, a plurality of external DBs and CDBs may be provided. When a plurality of external DBs are provided, it is not necessary to change the structure of the CDB if the information identifier absolutely indicates the storage location of the information regardless of the DB, such as a URL. However, when it is necessary to specify both the DB and the location of the information in the DB, it is necessary to store information indicating the location of the DB together in the CDB.
[0071]
  When a plurality of CDBs are provided, the number of CDBs may be increased as the amount of information increases. For example, it is possible to classify according to an appropriate standard such as providing a CDB for each channel.
(B) In the first embodiment, a case where a plurality of information identifiers are hit as a result of searching the CDB can be considered. Assuming such a case, as shown in FIG. 13, the function of the activation identifier receiving unit 13 in addition to the information identifier receiving unit 3 is added to the user terminal CC1, and the activation identifier operation is performed in addition to the information identifier operation unit 8. The function of the unit 19 is added to the user terminal CC2, and the user terminal CC1 is also connected to the CDB.
[0072]
  A user terminal CC1 shown in FIG. 13 includes a receiving unit 23 having the identifier detecting unit 21 and the access control unit 22 described above. The identifier detection unit 21 has the functions of the identifier detection units 1 and 11 described above, and detects the appearance of an information identifier and a DB activation identifier that appear in a chat conversation. The access control unit 22 has the functions of the access control units 2 and 12 described above. That is, the detected information identifier or DB activation identifier is sent to the DBAC application with reference to the identification flag, and access or search to the information storage location is activated. Therefore, the receiving unit 23 has the functions of the information identifier receiving unit 3 and the activation identifier receiving unit 13.
[0073]
  The user terminal CC2 has the information identifier operation unit 8 and the activation identifier operation unit 19 described above. Therefore, the user terminal CC2 detects a message including an operation instruction to the CDB that appears during a chat conversation, and operates the CDB according to the instruction. In addition, the user terminal CC2 detects a search instruction for a DB or CDB that appears during a chat conversation, and creates an activation identifier for the specified DB or CDB.
[0074]
  For example, when a plurality of identifiers are hit as a result of searching a CDB according to a search command specifying a keyword, the user terminal CC2 sends the number of information identifiers hit by the information identifier operation unit 8 to the chat application. Based on this remark, another user terminal remarks the same keyword as the CDB designation and the above. Based on this statement, the activation identifier operation unit 19 of the user terminal CC2 reads the CDB identifier from the DB list, creates a CDB activation identifier including the keyword, and sends it to the chat application. Other user terminals that have received this CDB activation identifier with the identification flag ON start searching for the CDB by keyword using the DBAC application, and obtain the hit information identifier as a search result.
[0075]
  Of course, the same functional configuration as that of the first embodiment may be adopted, and one of the information identifiers may be selected as a representative value by the identifier sending unit 7 and sent to the chat application. For example, the update date is stored together in the CDB, and the latest updated information identifier is selected.
(C) In the first embodiment, the same user terminal may have the information identifier receiving unit 3 and the information identifier operation unit 8. In this case, the user terminal 1 accessing the external DB can operate the CDB.
[0076]
  Similarly, in the second embodiment, a configuration in which the activation identifier receiving unit 13 and the activation identifier operation unit 19 are included in the same user terminal is also possible. In this case, the user terminal CC3 accessing the external DB can read the DB list 16.
(D) In the first embodiment, the chat server CS may have the information identifier operation unit 8. In the second embodiment, it is also possible that the activation identifier operation unit 19 is provided in the chat server CS.
[0077]
  (E) In the first embodiment, a configuration in which the external DB is included in the CDB is also conceivable. In other words, the CDB that stores the information identifier using the channel as a key has the actual information content. In this case, both the user terminal CC1 having the information identifier receiving unit 3 and the CC2 having the information identifier operation unit 8 access the CDB. However, in a chat channel, when a predetermined utterance including a search command is made, an information identifier read from the CDB is first uttered as a response. Based on this information identifier, the DBAC application operates independently and accesses the location where the information content of the CDB is stored. Accordingly, it is possible to prevent the display of the search result from interfering with the chat conversation. The commands other than the search can be operated in the same manner as described above.
[0078]
  (F) In the first and second embodiments, it is determined whether or not to access the DB based on the identification flag, but other methods are also possible. For example, each time the access control units 2 and 12 receive an information identifier or a DB activation identifier, the access control unit 2 or 12 confirms whether or not the user accesses the DB, and accesses the DB according to the input from the user. May be.
[0079]
  (G) In the above embodiment, the information identifier receiving unit 3, the information identifier operating unit 8, the activation identifier receiving unit 13, and the activation identifier operating unit 19 are provided independently of the chat application. It is also possible to incorporate it as part of the application and have it as part of the chat application.

【The invention's effect】
  According to the present invention, by providing a DB in which information is stored using a channel as a key, it is possible to share information while protecting privacy and to update the DB. Furthermore, by replying the information pointer as a search result in the shared space, the existing DB can be used as it is, and a plurality of DBs can be operated while having a comfortable conversation between the information terminals. By notifying the channel of the operation of the DB, it is possible to notify only necessary users of necessary information, so it is possible to prevent unnecessary information from overflowing or information leakage.
