  In the time series management method of the above-mentioned patent document 1, when a meeting record at a certain past time is searched, a search request instruction from the search request means is changed to a search request to which time series management data at the search time is added by the search management means. Converted. Based on the converted search request, the normal search means and the history search means perform a search. In the case of the above configuration, if there is time information, the search in the above configuration is effective, but if not, an effective search result cannot be obtained.

  In addition, when there are access restrictions on the conference information linked to the time information, it is necessary to perform a search taking into account the access restriction information and display according to the access correctness. There is no configuration means for holding information and restricting the search display.

  Further, in the history content display method of the workflow system disclosed in Patent Document 2, means for storing the processing content together with the history performed on the digitized document, and the processing content for the history having the processing content reference authority in the stored history information And means for determining the display of. In the above configuration, it is a reference authority for each work content. It is impossible to realize that information is allowed to be referenced and certain information is not allowed to be referenced. In addition, it is not possible to deal with a case where the reference authority changes according to the time axis.

  In view of the actual situation, an object of the present invention is to provide a conference history search apparatus that can solve the above-described problems.

The conference history search apparatus of the present invention stores storage means for storing conference record data having insertion / deletion time information in units of objects, means for displaying the conference record data stored in units of objects, and stores in units of objects. Means for searching the recorded conference record data, and means for displaying the conference state when the object of the search result is displayed.
Further, the conference history search device of the present invention includes a storage unit that stores conference record data having insertion / deletion time information in units of objects, a unit that stores types of conference units, and the conference record stored in units of objects. Means for displaying data; means for searching for the conference record data stored in units of the objects; means for displaying the conference state at the time when the object of the search result was displayed; A means for changing the access restriction adaptation method according to the information, a control means for controlling display and non-display based on the insertion time and deletion time information for each object, an insertion and deletion time, and a searcher's access restriction condition, And control means for controlling access to the conference record data based on the access condition of the record data.

  According to the present invention, it is possible to reproduce the progress of a conference by controlling the recording display of the conference according to the information on the insertion time and deletion time for each object. If the insertion / deletion time is ignored, it is possible to display all objects.

  In addition, by providing a means to change the access restriction adaptation method according to the type of recorded conference body, the access restriction for the conference conference record is limited to the participants who participated in the conference for a certain period of time. Allow all attendees including access to meeting records. However, for example, the restriction on access to the conference record of a budget meeting is that the participants who participated in the conference are allowed access to all conference records, but only part of the conference participates. Participants are allowed to access only the meeting records of the part they participated in. Thus, fine access management according to the type of the conference can be realized.

Reference numeral 3 denotes a general local area network, which communicates with other personal computers. Reference numeral 4 denotes a general personal computer, which is connected to the information device 1 in the actual usage form of the present invention through a local area network or the like. Using this device, it is possible to input search conditions and send the search conditions through the local area network 3. The information device 1 searches the conference record according to the search condition sent, and sends back the search result through the local area network 3.

  FIG. 2 is a block diagram of the portable information device according to the embodiment of the present invention. Reference numeral 2-1 denotes a general coordinate input unit, which is composed of a transparent resistance film digitizer or the like, and is connected to the CPU 6 via the system bus 11.

  A general image display unit 2-2 includes a liquid crystal display element, a liquid crystal control circuit, and a display memory, and is connected to the CPU 6 via the system bus 11. In response to an instruction from the CPU 6, a handwriting trajectory display and a character font display are executed.

  A general CPU 6 is connected to the RAM 7, the ROM 8, the image display unit 2-2, and the like via the system bus 11, and performs a processing operation by a program stored in the ROM 8.

  A general RAM 7 is used as a work area. Reference numeral 8 denotes a general ROM, which stores a conference record search processing procedure according to the present invention, a display processing procedure of the searched conference record, and the like. In addition, a control program for the image display unit 2-2 and other processing procedures are also stored.

  Reference numeral 10 denotes a general local area network interface card (LAN interface), which communicates with other personal computers. A general system bus 11 exchanges data between the CPU 6 and the ROM 8 / RAM 7 or other devices.

  FIG. 3 is a configuration diagram of the conference history search apparatus according to the embodiment of the present invention. Reference numeral 2-1 denotes a general coordinate input unit, which is composed of a transparent resistive film digitizer or the like, and can read XY-coordinate data of a locus written with a pen.

  3-1 is a handwritten character recognition means, which extracts a feature point of a handwritten character trajectory written by a general online handwritten character recognition algorithm, performs matching processing with a handwritten character dictionary, Using similar dictionary data as the first candidate, the input handwritten character string is converted into a character code string. This converted character string is used as a search character string.

  A search character string input unit 3-2 receives a character string serving as a search key from the handwritten character string recognition unit 3-1. Alternatively, a character string or the like input from a general keyboard and turned into a kana / kanji character by a kana / kanji conversion program is received as a search key character.

  3-3 is a conference record search means, which performs a search process from the conference record data 3-4 based on the character string sent from the search character string input means 3-2. At that time, the user access information 3-5 is referred to.

  3-4 is conference record data, which records conference records in object units. The insertion / deletion time is recorded in the one object. Also, the input user ID and the like are recorded.

  3-5 is user access information, in which the ID, participation time, and period information of the user who participated in the conference are recorded. A general image display unit 2-2 displays a conference record image or the like as a result of search by the conference record search unit 3-3.

  FIG. 4 shows a screen for inputting a handwritten character of a search key, and FIG. 5 shows a screen after the handwritten character is recognized. Reference numeral 4-1 in FIG. 4 denotes a handwriting search character string input area, and handwritten characters written in this area are recognized by a general algorithm. For example, it is divided into seven handwritten character trajectory data of “T”, “V”, “No”, “A”, “I”, “De”, “A” by a virtual character frame. Thereafter, the feature points of each character trajectory data are extracted, the degree of difference between the trajectory data stored in the dictionary and the feature point data is calculated, and the most similar dictionary data is output as the recognition result.

  When all the recognition processes are completed, the font display shows “TV idea” as shown in FIG. When the input of the search character string is completed, the search process is started by pressing the search key 4-2.

  FIG. 6 is a diagram illustrating an example of one screen for recording a meeting. A single character string is handled as one object. In the example of FIG. 6, “DTV idea conference” is one object, and “☆” is one object.

  FIG. 7 is a data structure diagram of the conference record object. The object of the conference record is composed of an object ID, object data, insertion time deletion time, and entry user ID.

  The object is identified based on the object ID. Although omitted here, there is information on the display position.

  Insertion time is the time when the object was written. The deletion time is recorded when the object is deleted. The object is not displayed from the normal display on the conference screen, but is recorded as data and is therefore a search target.

  The entry user ID is used to determine the user who entered, and is determined by inputting a user name or the like when participating in the conference system.

  Since this conference system can participate from a PC connected via a network, at that time, a normal authentication process is performed by inputting a user name password or the like.

  Also, in the case of using an input / output integrated device such as an electronic blackboard that combines a thin display and a digitizer, an embodiment in which the pen attached to the digitizer is given an ID and the pen is changed for each user is also considered. It is done.

  FIG. 8 is a data structure diagram of user access information. The conference ID, the user ID, the participation start time of the user, and the leaving time are recorded. The conference ID can be specified by the conference ID.

  In the example of FIG. 8, the users who participated in the conference of “conference ID: 001” are “0123, 0333, 0331, 055”, and the participation start time is known. The conference is still ongoing. In some cases, there is a user who has not filled in the exit time.

  FIG. 9 is a flowchart of the conference record search process. FIG. 10 is a flowchart of search result display processing. First, the process will be described with reference to the flowchart of FIG. As described in the data structure diagram of the conference record object in FIG. 7, the conference record is recorded in units of objects.

  In step S9-1, the conference record search process is started. First, the work area and the like are initialized. This processing is called when a search keyword has already been input as shown in FIG. 5 and the search button is pressed.

  In step S9-2, the retrieval key object is read. The result character string written and recognized in the handwriting search character string input area 4-1 displayed in FIG. 5 is stored in the buffer area. In the example of FIG. 5, “TV idea” is stored.

  In this example, a process for performing a search with a character string will be described, but a trajectory object can also be searched with a handwriting trajectory. In that case, the entered handwriting trajectory is directly stored in the search buffer, and the handwriting trajectory data is matched with the handwriting trajectory object in the stored conference record to obtain the most similar object. Processing is performed so as to find out as a search result.

  In step S9-3, the user ID of the searcher is read. The user ID itself is set by a general login process. The stored user ID is stored in the work area.

In step S9-4, the recorded conference record file is sequentially read. The first file of the meeting record file shown in FIG. 7 is read into the storage buffer.

  In step S9-5, it is determined whether there is an object that matches the stored search key. If there is an object matching the search key in the meeting record file read in step S9-4, the process proceeds to step S9-8, and if there is no corresponding object, the process proceeds to step S9-6. Read the objects in the meeting record file one by one, check the matching degree between the object data and the search key object. If they match, finish the process, and if they do not match, read the next object and search. Check the degree of coincidence with the key object.

  In step S9-6, it is checked whether the next file exists. If the next file exists, the process proceeds to step S9-4. If the next file does not exist, the process proceeds to step S9-7, and this process ends.

  In step S9-7, the process ends without a search target file. The degree of coincidence between all the objects in all the meeting record files and the search key is inspected, and if there is no matching object, the process ends with no corresponding file in the search result.

  In step S9-8, a process for reading the conference access information is performed. In step S9-5, the conference file ID is read from the conference file that matches the search key, and the data corresponding to the conference file ID is read from the user's conference access information file shown in FIG. 8 and stored in the buffer. For example, if the conference file ID is “001”, in the example of FIG. 8, the first four data are read and stored.

  In step S9-9, a process for checking whether the conference file is accessible is performed. If there is a user ID that matches the search user ID in the conference file, the conference file can be accessed, so the process proceeds to step S9-10. Otherwise, the process cannot be accessed, and the process proceeds to step S9-6.

  The user ID data of the conference file ID read in step S9-8 is compared with the user ID read in step S9-3. For example, if the user ID read in step S9-3 is “0333” and the user ID data of the conference file ID read in step S9-8 is “0123, 0333, 0331, 0555”, the second “0333” ".

  In step S9-10, a process for storing the conference file is performed. Here, the same object as the search object exists, and data is stored in the buffer in order to display an accessible conference recording file.

  In step S9-11, the search process is terminated. Open work areas that will not be used in the future. In the process of the flowchart of FIG. 9, when one meeting file that matches the search key is detected, the process ends there. However, since there may naturally be a plurality of conference files, it is better to store the detected file and search for the next file.

  In addition, when there is an object having a 100% matching degree between the user search object and the object in the conference record, it is set as the first candidate, and the objects are sequentially placed in the descending order of the matching degree. Even objects with a matching degree of 30% or more are treated as matching objects. This is because if the matching part is 30% or less, a situation such as the fact that the search key is roughly incorrect can be considered.

  In step S10-1, search result display processing is started. Initialize the work area.

  In step S10-2, a process of reading a conference file as a search result is performed. The conference file stored in step S9-10 is read out to the work area.

  In step S10-3, the display mode is checked. In the case of a conference record search result, multiple display modes are possible. For example, if you want to reproduce the state at a certain point in the meeting, if you want to know the final result, or if you want to know all the opinions and ideas that were given at the meeting, there are three such display modes. Here, check which mode is now.

  In step S10-4, the searcher's user ID is read. The process itself is the same as the process in step S9-3. The user ID itself is set by a general login process. The stored user ID is stored in the work area.

  In step S10-5, the time information of the search object is read. In step S9-5, insertion time deletion time information which is time information of the searched object is read and stored in the work area. For example, when the search result is “+ regional circulation broadcasting” with the object ID “005”, “2005/05/24/10: 15 12:30” that is the insertion / deletion time is stored.

  In step S10-6, processing for sequentially reading objects is performed. The conference recording object ID shown in FIG. 7 is read sequentially from “001”.

  In step S10-7, it is checked whether the time information is within the range. Check if the object exists within the time range of the searched object. If the object is within the time range, the process proceeds to step S10-8; otherwise, the process proceeds to step S10-10. For example, it is assumed that the time read in step S10-5 is “2005/05/24/10: 15 12:30”. Displays objects that existed during that time. Since the object ID: “001”, “DTV idea meeting”, and “2005/05/24/8: 00” in FIG. 7 are the insertion time and the deletion time is not recorded, it is within the time range. move on.

  Also, if the object ID of “006” in FIG. 7 is “☆”, the insertion time is “2005/05/24/13: 15”, so it is out of time, so no display is performed, so the process proceeds to step S10-10. Proceed to processing the next object.

  In step S10-8, it is checked whether access is possible. If accessible, the process proceeds to step S10-9, and if not accessible, the process proceeds to step S10-10.

  In this embodiment, if the user is a conference participant, this object is displayed if the user ID of the searcher is included in the user ID of the access information of the conference. If the access restriction is such that only the object written by the user can be displayed, control may be performed to display only the object having the same user ID of the object data and the user ID of the searcher.

  In step S10-9, an object is displayed. In this example, an object that is displayed within the same time range as the searched object and is accessible is displayed on the display screen. If the configuration is such that a search instruction is issued from the network, the display data determined in this process is sent over the network and displayed on the device connected to the network.

  In step S10-10, it is checked whether there is a next object. If there are still objects to be processed, the process proceeds to step S10-6, and if all objects have been processed, the process proceeds to step S10-11.

  In step S10-11, the search result display process ends. Release the secured work area. By configuring the processing in this way, it is possible to retrieve data written and deleted during the conference from the conference record data. And the meeting history search apparatus which can display the state of the meeting when the data was displayed is realizable. In this way, since the state of an idea that was erased at the meeting can be reproduced later, the user's desired environment can be constructed as a search result of the meeting record.

(Second Embodiment)
In the first embodiment, a process for searching for a record of a conference has been described. However, there may be a case where access restrictions differ depending on the type of conference. Thus, in addition to the configuration of the first embodiment, an embodiment will be described in which means for changing the access control restriction range and restriction method for recording depending on the type of conference is provided.

  FIG. 11 is a configuration diagram of a conference history search apparatus according to the second embodiment. Parts having the same configuration in the configuration diagram of the first embodiment in FIG. 3 have the same part numbers.

  Reference numeral 11-1 in FIG. 11 denotes a conference type access restriction adaptation unit that changes and adapts the control method of access control to the conference record object in accordance with the type of conference recorded.

  FIG. 12 is a structural diagram of an access restriction adaptation table according to the type of conference according to the second embodiment. It consists of a conference type and a description of an access restriction adaptation rule.

  For example, in the case of an idea meeting or the like, all participants should share ideas and the like, and all the visitors can search for and display objects of the meeting record. Alternatively, a process may be considered in which a participant who has participated only in a certain part of a meeting at a budgeting meeting or the like is allowed to search and display a record of only the other part.

  FIG. 13 is a diagram illustrating an example of a conference start instruction screen according to the second embodiment. The user is allowed to select the type of conference shown in 13-1, 13-2, 13-3 at the start of the conference, and if the setting is acceptable, the user presses the setting button 13-4.

  In this embodiment, the configuration is set at the start of the conference, but it may be necessary to change the type of conference during the conference, or more types may be necessary, but such a configuration is also applicable to this configuration. It is possible.

  FIG. 14 is a data structure diagram of a conference record object according to the second embodiment. In addition to the data structure of the conference record object shown in FIG. 7, the conference ID for determining the conference, the data indicating the conference type, and the conference time information are configured by the start time, the end time, and the like.

  FIG. 15 is a flowchart of search result display processing according to the second embodiment. The processing will be described along the flowchart of FIG.

  In step S15-1, search result display processing is started. Initialize the work area.

  In step S15-2, a process for reading a conference file as a search result is performed. The conference file shown in FIG. 14 stored in step S9-10 is read into the work area.

  In step S15-3, the conference type is checked and access processing is determined. If the conference type of the conference file of the search result is an idea review or specification review, the process proceeds to step S15-4. If the conference type is a budgeting conference, the process proceeds to step S15-5. The process proceeds to step S15-6.

  In step S15-4, an adaptation rule for restricting access to objects in the idea review meeting is adapted. Here, since it is an idea review meeting, it adapts with the adaptation rule which discloses information to meeting participants.

  In step S15-5, an adaptation rule for restricting access to objects in the budgeting meeting is adapted. Here, since it is a budget organization meeting, it is adapted by an adaptation rule that makes the information public to the participant when the object is displayed.

  In step S15-6, an adaptation rule for restricting access to objects in the public discussion is adapted. Here, since it is a public discussion, it adapts with the adaptation rule which displays all the objects.

  In step S15-9, a process for displaying all objects is performed. The conference record file object ID: “001” shown in FIG. 14 is sequentially read and displayed.

  In step S15-7, the process proceeds to step S10-1. Since the adaptation rule disclosed to the conference participants is the process described in the flowchart of FIG. 10, the process proceeds to step S10-1.

  In step S15-8, a process of reading the searcher's conference participation time from the access information is performed. For example, in the example of FIG. 8, if the user has the user ID: “0555”, the participation time is “2005/05/24/13: 00” and the leaving time is “2005/05/24/15: 00”. So it is memorized.

  In step S15-10, processing for sequentially reading the objects of the conference recording file is performed. The conference recording files shown in FIG. 14 are sequentially read from the object ID “001”.

  In step S15-11, it is checked whether the object is within the participation time. If the object is within the participation time, the process proceeds to step S15-12; otherwise, the process proceeds to step S15-13. For example, if the participation time is “2005/05/24/13: 00” and the leaving time is “2005/05/24/15: 00”, the example of the conference file in FIG. ”And“ 2005/05/24/13: 15 ”, respectively, the object is displayed.

  In step S15-12, an object is displayed. Only the objects that were seen at the time of the meeting in which the searcher was participating are displayed. In this example, such processing is performed. However, processing that allows access to all objects in the case of a user ID with the same hierarchical access authority as that in the actual management hierarchy for a user ID higher than the general manager is also added to the user ID. You may do it.

  In step S15-13, it is checked whether there is an unprocessed object. If there is a next object, the pointer or the like is set as the next object, and the process proceeds to step S15-10. If all objects have been processed, the process proceeds to step S15-14.

  In step S15-14, the search result display process ends. Release the secured work area. Close the opened file.

  By configuring the processing in this way, it is possible to realize a conference record search / display apparatus that can apply different access restriction processing depending on the type of conference body of the conference record.

  In the example described in the first embodiment and the second embodiment described above, the example of the electronic conference outgoing in the local environment has been described. However, since this conference system itself is an electronic device, it is naturally connected via a network. Since it is possible to participate from a distant terminal, the remark data and the entry data that participated on the net are also handled as one object. In addition, text data, trajectory data, and voice data can be input as search keys from a remote terminal connected via a network, and can be displayed.

  Further, as another embodiment, there are provided meeting record data storage means having insertion time / deletion time information for each object, access restriction means for stored data, and means for storing access management data having access time limit information of access data You may make it have. In this case, even if a part of the conference record is restricted, it is possible to realize a process in which an object that is not restricted is displayed as a search result and the restricted object is hidden. In addition, an apparatus that can retrieve ideas that have been deleted along the way in the course of the meeting can be realized. Further, according to the access time limit information, it is possible to disclose and search information for a certain period of a certain conference record, but it is possible to realize an access restriction that does not disclose information for other periods.
