Description

  The present invention relates to an information sharing system, and in particular, can compare various types of information input in a plurality of information terminals connected via a network, aggregate and classify a plurality of information, and share the information without paper. The present invention relates to an information sharing system.

Conventionally, in meetings such as brainstorming, the chairman presents the agenda, for example, and each participant submits an answer, suggestion, or idea to the agenda, and the answer proposals submitted by the secretary are aggregated and classified After that, the procedure is performed to distribute the result of the aggregation to the participants.
In such a meeting, each participant may input his / her answer on paper or suggest an idea verbally. In any case, after collecting each participant's answer or idea, It was necessary for the person in charge to carry out operations such as judgment of differences in many answers and classification and aggregation of ideas.

  In addition, as a device for determining whether a handwritten answer is correct or incorrect by a computer, a correct answer or an error is determined by comparing the stroke order and shape of characters handwritten and the correct stroke order and shape of characters or the like previously stored in the storage means. There has been proposed a learning device that can learn the writing order or the correct shape of characters by determining the answer and displaying correctness (see Patent Document 1).

  In addition, handwritten characters written on the handwriting input device are compared and analyzed with the correct number of strokes, stroke order, character shape, etc. of the characters stored in advance in the storage means, and the correctness determination is comprehensively performed on the display device. The judgment result is displayed, and the correct characters and handwritten characters are superimposed and displayed at the same time, or each character is color-coded for each stroke according to the stroke order, and the stroke number, stroke order, character shape, etc. are compared, A handwriting input pattern correct / incorrect determination system has been proposed in which a child can practice "character" alone by determining correctness of handwritten input characters and giving appropriate attention (Patent Literature). 2).

  In addition, the host side equipped with an input device and a computer, a monitor TV, etc. and the terminal side equipped with a computer, a monitor TV, etc. are connected by a communication line, and handwriting input is performed on the host side and the terminal side as one of the input means. The terminal has an input pattern written on this handwritten input tablet, received by the host, and compared with a standard pattern stored in advance in the computer, as well as corrections such as evaluation, diagnosis, correctness determination, etc. by the corrector To the terminal side and display the judgment result on the monitor TV, giving the judgment result etc. for each terminal separately from the host side, carefully where each child using each terminal is not known A correction guidance system that repeatedly teaches has been proposed (see Patent Document 3).

  In addition, themes are presented to participants via a computer network, and participants generate information from the presented themes and provide them to the organizers online. The organizers sort and organize the information groups provided A brainstorming method has been proposed in which an evaluation based on the level of significance is given and disclosed on a list screen, and a reward is paid based on the evaluation result (see Patent Document 4).

However, if the participants hand-write the answers on paper without using a computer, or if the clerk writes the ideas proposed verbally by the participants, the answers are aggregated and classified. However, it took a lot of work and time.
In addition, when a large number of people participate, the participant may have to wait for a long time until the result of counting is obtained.
In particular, if you propose your own ideas for a certain agenda, or if the answers are not uniform, combine similar ideas into one, or group the same answers semantically into one group. It may take a long time, and it was difficult to provide the results to the participants promptly.

  In addition, all of those described in the conventional patent documents (1 to 3) provide a specific user who uses each system with determination results and learning information appropriate for the user. In addition, in a meeting or the like in which a large number of participants participate, the information submitted by a plurality of participants is not collected and classified, and thus the above-described problems cannot be solved.

In addition, each participant can know what ideas have been created by looking at the results after the aggregation, but the ideas of other participants can be referred to during the idea review stage. There wasn't. In the conventional patent document (4), the information presented by a plurality of participants is aggregated and classified, but the organizer is present in the middle, so the whole idea is devised. It takes time, and the display / edit screen simply lists the participants' ideas, so there is a problem in that visibility and operability are significantly impaired when the number of participants and ideas increases.
In other words, based on the idea of brainstorming, based on the ideas of other participants and trying to come up with a different idea that can be recalled from it, it has been done only after the total idea has been aggregated and classified. There was a problem that I could not.

  Therefore, even in the information sharing system that can quickly provide the aggregated results to each participant and the idea review stage, it is possible to easily refer to ideas already written by other participants as necessary. It is desirable to use an information sharing system that allows easy input.

  Therefore, the present invention has been made in consideration of the above-described circumstances, and a plurality of participants in the conference can easily input information such as ideas, and the input information of the plurality of participants.

<Configuration of Information Sharing System of the Invention>
FIG. 1 shows a schematic configuration diagram of an embodiment of an information sharing system according to the present invention.
In FIG. 1, the information sharing system of the present invention is mainly composed of one server 1 and a plurality of information terminals (hereinafter also simply referred to as terminals) 2.
The server 1 and each information terminal 2 are connected via a network.

The server 1 is an information management device that stores and provides shared information and the like. The server 1 mainly stores various information transmitted from the terminal, manages user information, approves the operation mode of the terminal, and summarizes write data. And processing such as classification processing, user authentication, device authentication, and communication encryption.
In addition, the information terminal 2 has a first function in which a person who submits the agenda of the meeting (for example, the chairperson) creates an agenda and sends it to the server, and a participant, who participates in the meeting, own answers, opinions, and ideas And a second function for writing the contents of the proposal and the like, and which function is used is selected at the time of activation by the operation of the user of the terminal.

Hereinafter, a terminal that executes the first function is referred to as a registration mode terminal, and a terminal that executes the second function is referred to as a conference mode terminal.
In order to make the terminal versatile, it is desirable that all terminals participating in the conference have two functions in advance.
In addition, according to the present invention, when the terminal is activated, the user is allowed to select and input which mode is to be executed. Corresponding to the selected mode, the activation process is performed so that a function preset in the mode can be executed.
For example, when “registration mode” is selected on the terminal, registration mode activation processing is executed, and registration processing of the agenda to the server can be performed thereafter. In this registration process, information (terminal mode notification) indicating that the terminal is activated in the “registration mode” is transmitted to the server.

However, a registration mode dedicated terminal having only the first function for the agenda submitter and a conference mode dedicated terminal having only the second function for the participants in the conference may be provided.
The server 1 may be mainly owned by the agenda submitter, or may be installed in an ASP (Application Service Provider) or a network service provider facility.
On the other hand, the terminal 2 may be a personal computer or a portable terminal owned by the participant, or an information processing device installed in a company or the like.

When a user logs in at a terminal, the user inputs user information including a name, a user ID, a password, etc., and these user information is transmitted to the server and registered in the server in advance. It is determined whether or not the user can participate in the conference by checking with the user information of the existing user. If the verification is successful, the operation mode selected by the terminal is transmitted to the server.
After receiving the approval notification from the server, the terminal (TE0) activated in the registration mode can input or edit the agenda, and the agenda is transmitted to the server. The server stores the agenda. This agenda becomes shared information distributed to a plurality of terminals.

  In the terminals (TE1 to TEn) activated in the conference mode, the agenda, which is shared information distributed from the server, is displayed on the display screen of each participant's terminal, and the answer related to the agenda given to the participant. Write data such as can be input. After the write data is input, the write data is transmitted to the server.

The server stores the received write data in a so-called multilayer structure. Thereafter, the server performs analysis processing on the agenda using the write data sent from a plurality of participants. In this analysis process, for example, the number of the same write data is counted, or a process for classifying synonyms as data of the same group is performed.
The results of aggregation and classification by the server (hereinafter referred to as aggregation results) are transmitted from the server to each participant's terminal in response to the aggregation request from each terminal and displayed on the screen of that terminal.
Here, it is preferable that the tabulation result is displayed as a chart that allows the write data classified into the same group and the tabulation number of the same write data to be visually understood.
The above is the outline of the information communication performed between the server of the present invention and each terminal.

The server 1 and the terminals 2 (TE1 to TEn) may be connected directly by, for example, a wired communication cable, or may be connected by a wireless communication method such as a so-called wireless LAN.
Further, the server 1 and the terminal 2 may be connected via various networks (LAN (N1), Internet (N2), dedicated communication network (N3), etc.).
When the user uses the terminal (TE1) in the conference mode, after the communication line between the terminal TE1 and the server 1 is connected and the link is established, the write data created by the terminal TE1 is stored in the server 1 Sent to.
At this time, it is desirable to encrypt transmission data (for example, AES: Advanced Encryption Standard, 3DES: Triple-Data Encryption Standard, etc.) in consideration of confidentiality and confidentiality in information transmission of write data and the like. Further, lossless compression encoding of data may be performed for the purpose of reducing the amount of network transmission.

<Description of automatic tally processing>
The present invention is characterized in that a server performs analysis processing on shared information such as an agenda using a plurality of write data sent from a plurality of terminals, and automatically generates a total result. Mainly, write data handwritten by the participants are compared to determine whether or not they are the same, and the same write data or a plurality of write data determined to be within a predetermined similar range Categorized as data of the same group.
Here, the analysis process includes a classification process that divides a plurality of write data into several groups, and a total process that counts (counts) the number of the same write data.
When multiple write data are transmitted from the terminal to the server, the classification process considers the write data in which the same content or similar content is entered as belonging to the same group, and different content. The written data entered is considered to belong to different groups, and several groups are set.
For example, if there are four types of different data among ten pieces of write data, four groups (A, B, C, D) are set, and the ten pieces of write data belong to the corresponding groups. Classify as follows.

Further, in the aggregation process, the number of the same write data belonging to one group is counted.
For example, when three participants input the same write data, the write data is classified into one group, and the total number of the write data is set to “3”. In the classification process, any two pieces of write data transmitted to the server are selected, and the two pieces of write data are compared with each other to determine whether or not they are the same data, or within a predetermined similar range. It is checked whether or not it can be determined as write data.
For example, write data that are synonyms that are semantically similar, such as “Sakura” and “Sakura”, are determined to be write data within the similar range and are classified as belonging to the same group.

  Such classification processing is mainly performed by comparing character string data input by a keyboard or the like, comparing stroke information input by a tablet or the like, and character string data obtained by converting stroke information by handwritten character recognition as shown below. The comparison is made by comparing the write data sent from a plurality of terminals by using the comparison using the language processing such as the comparison and the semantic analysis.

(1) Comparison of character string data When the two write data are both character string data, the character string data are compared.
Here, a code (character string data) given in advance to a character input using a keyboard or the like is compared.
For example, when certain write data A is character string data “tulip” input using a keyboard, other write data B is also a character string “tulip” input using a keyboard. In the case of data, the character codes of the respective characters are compared, and when all the character codes match as the entire character string data, it is determined that the write data A and B are the same.
On the other hand, if there is even one different character code in the character code of the character string, it is determined that both write data are different.
However, even if the write data is different, those that are considered to be semantically the same or similar may be determined to belong to the same group.
For example, as write data having the same meaning, three character string data “sakura”, “sakura”, and “sakura” are registered in the database in advance, and the two write data are registered with each other. If it matches any of the character string data, it may be determined that they belong to the same group. Thereby, flexible classification becomes possible.

(2) Comparison of input stroke information This is one of the comparison methods when writing data is input by handwriting input using a tablet. Characters and symbols in which two writing data are input by handwriting are compared. In this case, the stroke information of the characters and symbols input by handwriting is compared.
For example, when the character “sakura” is input by handwriting, it is recognized as a lump shape in which several line segments are overlapped, and the start point and end point of each line segment are relative position information (stroke information). ). Compare the stroke information that forms the character "sakura" handwritten by one participant with the stroke information that forms the character "sakura" handwritten by another participant. Are within the predetermined similarity range, they are determined to be the same character, and are classified into the same group.
Further, if the handwritten character “sakura” and the stroke information of the handwritten character “peach” are not within the predetermined similarity range, they are determined as different characters and classified into different groups.
If it is determined that two characters are the same character, the total number of the characters is set to “2” in the total processing.
When three or more people write the same character, the total number is counted for the number of people.

(3) Comparison by Handwritten Character Recognition Here, character data obtained by converting stroke information input using a tablet or the like by handwritten character recognition is compared.
For example, when a participant inputs the character “sakura” by handwriting, the character recognition database and the character recognition algorithm (characteristic patterns such as handwritten strokes or character images and the character recognition database that are conventionally used) are recorded. The input character is recognized using the matching with the recognition dictionary pattern), and character string data “sakura” is extracted as the recognition result. Also, the same character recognition processing is performed for characters handwritten by other participants, and if the character data that is the recognition result is the same character string data “sakura”, both write the same character. Are classified into the same group, and the total number of characters is set to “2”.
On the other hand, if a character handwritten by another participant is recognized by different character string data other than “sakura” (for example, “peach”), it is determined that both characters are different characters, Classify as character.

(4) Comparison using language processing Here, after the handwritten character recognition of (3) described above, the writing data that is semantically similar is treated as the same or similar, apart from the recognition result itself. In order to do so, the recognition result is compared with a predetermined language process.
For example, when handwritten input writing data is recognized as character string data “Sakura”, language processing is performed on this “Sakura”, and characters such as “Sakura” and “Sakura” Although the expressions are different, the same semantically are handled as if the same write data was input.
That is, when other participants input the hiragana character string “Sakura” by handwriting, the character recognition process recognized the character string data consisting of three characters “sa”, “ku”, and “ra”. However, the character string data of “Sakura” does not match the writing data “Sakura” of another participant, but “Sakura” and “Sakura” may be considered to be semantically identical by language processing. Since it is possible, it is determined that the same data has been written. “Sakura” and “Sakura” determined to be the same data are classified into the same group.
Here, as language processing to be used, for example, hiragana, katakana, paraphrase processing between kanji characters, similarity determination processing, thesaurus database analysis processing, morpheme analysis processing, and the like can be used. Any one of these may be used, and some of these processes may be combined.
By using the comparison process as described above, automatic classification is possible even when a user inputs a character string by handwriting using a tablet.

<Configuration of information terminal>
FIG. 2 shows a configuration block diagram of an embodiment of the information terminal of the present invention.
The information terminal 2 (TE) of the present invention mainly includes an input unit 11, a display unit 21, a communication unit 31, an authentication unit 41, an external storage IF unit 51, a storage unit 61, and a control unit 71.

The input unit 11 includes a pointing device such as a keyboard 12, a mouse 13, and a tablet 14, and includes an input processing unit 16 that receives these inputs and converts them into signals for transmission to the control unit 71.
From the input unit 11, user login information, agenda that is shared information, write data related to the shared information, and the like are mainly input, and input such as an aggregation request and mode selection is also performed.

Of the input unit 11, the keyboard 12 inputs character string data and symbol data, and code information for the input character string data and the like is output as an input signal.
The tablet 14 is used to input write data as handwritten information, and includes an input detection unit arranged on the display screen of the display unit 21. Handwritten information is input by pressing a finger or a dedicated input pen against the input detection unit. The handwritten information is input as stroke information connecting the start point and end point of the line segment.

Various types of conventionally used methods such as a resistance film type, a capacitance type, and an infrared type can be used for the input detection unit of the tablet 14. Moreover, you may use the optical sensor liquid crystal etc. which integrated the display part and the input part.
For example, when the agenda, which is shared information, is displayed on the display unit, the write data is input by handwriting into the input detection unit corresponding to the write data input area in the display screen.

In addition, when the agenda and the already written data of other participants are given as shared information, the agenda and the written data of other participants are not overlapped on the display unit. Display. However, the write data of other participants may not necessarily be displayed.
When there are already two or more write data of other participants, they are displayed so as not to overlap each other. In this case, the participant can see the displayed agenda and the other participant's writing data, and input his / her writing data to the input detection unit by handwriting.
At this time, it is preferable that the position where the user's own writing data is input by hand is different from the position where the writing data of other participants is displayed. Further, as shown in FIG. 32, the current automatic classification / aggregation status may be displayed so that the entire drafting status of all participants can be grasped.

  The display unit 21 is a part that displays the agenda, shared data of others, or various input selection screens that are shared information, and a display 22 such as an LCD or CRT and a display that generates a display signal to be displayed on the display 22. And a processing unit 23.

The communication unit 31 performs data transmission and data reception with the server, and performs data communication control so that data communication can be performed with a predetermined communication protocol via various networks. Also, data encryption processing (for example, AES: Advanced Encryption Standard, 3DES: Triple-Data Encryption Standard, etc.) and data compression processing are performed as necessary to conceal data and reduce the amount of data. .
Therefore, it is desirable that the communication unit 31 includes a communication encryption unit 32 and a communication decryption unit 33.

  The authentication unit 41 is a part that performs user authentication and login authentication to the terminal and the information sharing system, and mainly checks the user ID and password registered and managed in advance by inputting the user ID and password of the user. By doing so, authentication is performed.

The storage unit 61 stores information such as terminal user information (user information), various types of input information, display information, transmission / reception data, and shared information distributed from the server.
The storage unit 61 stores, as input information 62, for example, participant user information 62-1 and self-written data 62-2 written by a participant who uses the terminal. When the terminal is activated in the registration mode, the agenda is stored as one piece of input information.
In addition, as reception shared information 63 distributed from the server, agenda 63-1 and other person write data 63-2 already written by other participants are stored. As the shared information, the agenda is indispensable information, but the other person's write data may not be included in the shared information. For example, when the chairperson registers the agenda in the server, the write data of the participant may not be shared information and may be set not to be distributed to other participants.
The user information 62-1 is information for identifying a person who uses the terminal, and is information including a user name, a login name, a password, and the like of the participant, for example. This user information 62-1 is also transferred in advance to the server, and stored as user information 142 in the storage unit 141 of the server.

The agenda 63-1 in the storage unit 61 is data input by the chairperson or the like who proceeds with the conference, and is, for example, a document file such as “Please enter a flower you can come up with” as will be described later. The document file is a file created by various application programs, and the created program is not particularly limited.
Further, the document file of such an agenda need not be created by the terminal of the present invention, and may be created by another personal computer or server. The agenda 63-1 may include a page including only the agenda itself and a page including an agenda and a writing data entry field.
Hereinafter, the created original file of the agenda is also referred to as an agenda source file.
This agenda file is transferred to the server and stored in the storage unit 141 of the server.

The agenda 143 stored in the server is imaged for each page (image processing) so that it cannot be directly written or changed when it is distributed to the participants later. In other words, the server stores the original file of the received agenda in the storage unit 141 after image conversion.
For example, as shown in FIG. 4B, an agenda source file consisting of 8 pages “Agenda 001.doc” is converted from “a01.jpg” to “a08.jpg” after image conversion for each page. Are stored as eight image files (image conversion files).
A plurality of image files after image conversion constituting one agenda are stored in a layer structure, displayed on the display for each page, and the user can perform page operation by page operation and page input in order to perform page operation. To be able to move forward and backward.

The self-written data 62-2 and the other person written data 63-2 are data input at the terminal activated in the conference mode.
When inputting these writing data, for example, while displaying the pages of the agenda as shared information on the display sequentially, the information considered by the user is input on the tablet by handwriting.
Here, the write data is not input to the agenda page or the other person's write data page itself, but is input as different page information (write information) displayed superimposed on the agenda page. The input of the writing data is performed while the participant sees shared information such as the agenda displayed on the display. The input is performed by, for example, input using the keyboard and mouse of the input unit 11 or handwriting input using a tablet. That is, the agenda and the write data are stored as separate files, and each page of the agenda, the other person's write data, and the newly written self-written data is stored with a relative layer structure.

  Moreover, it is preferable to store the input position information of the write data so that the input position does not overlap with the display position of the agenda or other person write data. As a result, when the page of the agenda or other person's write data and the newly input page of write data are displayed in an overlapping manner, the input position of the new write data, the agenda and the other person's write Since the data can be displayed so as not to overlap with the display position of the data, the user can easily confirm the agenda and the plurality of write data on the same screen.

The external storage IF unit 51 is an interface part that connects the external storage device 50 storing the agenda file to a terminal.
For example, as the external storage device 50, a storage medium such as a CD or a DVD, or a portable memory such as a USB memory or a card type memory can be used.
A user who creates an agenda may create an agenda in advance using another personal computer or the like, save it in the external storage device 50, and connect the external storage device 50 to the external storage IF unit 51 of the terminal.

In addition, as a method of transferring the agenda to the terminal, in addition to this, the personal computer used for creation is directly connected to the terminal with a cable, or from a personal computer storing the agenda via a network such as a LAN. You may make it download.
As the storage unit 61, a semiconductor element such as a ROM or a RAM, a storage medium such as a hard disk, a CD, a DVD, or a USB memory is used.
The storage unit 61 also stores a program for executing each function of the terminal TE.

The control unit 71 is a part corresponding to a microcomputer including a CPU, a ROM, a RAM, an I / O controller, a timer, and the like. When the CPU reads a program stored in the storage unit 61 into a RAM (main memory). The various functions of the terminal are executed by operating various hardware organically.
In FIG. 2, eleven functions are shown in the control unit 71 from the login request unit 72 to the totaling result receiving unit 82, but the realized functions are not limited to this.
Each function of these functional blocks is realized by the CPU executing predetermined processing using information input from the input unit 11 based on a program for each function.

In FIG. 2, a login request unit 72 is a part that transmits login request information to the server when the user of the terminal performs an operation that means login. For example, the login request information includes data including user information, IP address, terminal ID, and the like.
The terminal mode notification unit 73 is a part that transmits terminal mode information to the server. This transmission information includes information for specifying one of “registration mode” and “conference mode”.
For example, a terminal that has transmitted information indicating that it is in “registration mode” is activated as a terminal in registration mode after receiving an approval notification from the server, and can enter an agenda.

The logoff request unit 74 is a part that transmits logoff request information to the server when the user of the terminal performs an operation that means logoff. For example, the logoff request information includes data such as user information, an IP address, and a terminal ID.
The logoff processing unit 75 is a part that actually logs off the terminal when receiving information permitting logoff from the server. As the logoff process, for example, a process of logically disconnecting from the server or a process of terminating the use of the terminal is performed.
When the user information is centrally managed on the server side, the authentication of the terminal and the authentication of the entire information sharing system through the server are made common, and the authentication unit 41, the login request unit 72, the logoff request unit 74, and the logoff processing unit 75 are integrated. It may be configured.

The registration mode activation unit 76 is a part that activates the terminal as the registration mode when the registration mode notified to the server is approved by the server. Here, for example, a process of displaying a menu list of functions executable in the registration mode on the display is performed.
After that, by performing a predetermined operation, the agenda can be input, transmitted and displayed.

The conference mode activation unit 77 is a part that activates the terminal as the conference mode when the “conference mode” notified to the server is approved by the server. Here, for example, processing for displaying a menu list of functions executable in the conference mode on the display is performed.
After that, by performing a predetermined operation, it becomes possible to display the agenda and input, transmit and display the write data.

The agenda transmission unit 78 is a function that can operate on a terminal activated as a registration mode, and is a part that transmits the agenda created on the terminal to the server. That is, the agenda source file is transmitted to the server.
The write data processing unit 79 is a function operable on a terminal activated as a conference mode, a process of inputting write data at the terminal, a process of transmitting the input write data to the server, and a process of writing from the server This is a part that performs processing for receiving a notification indicating that registration of embedded data has been completed.

The shared information processing unit 80 is a part that transmits or receives shared information to the server.
For example, the terminal activated in the registration mode transmits the input agenda to the server.
Further, the terminal activated in the conference mode receives the agenda that is shared information from the server. Alternatively, when the other person's write data that can be viewed already exists in the server, the agenda and the other person's write data are received from the server.

The aggregation request unit 81 is a function that can operate on a terminal activated as a conference mode, and is a part that transmits information requesting the server to aggregate and classify write data at the terminal. This request information includes, for example, data such as user information, IP address, and terminal ID.
In addition, the request for aggregation is made after the input of the own write data is completed in principle, but it is preferable to make it possible to review the own write data as necessary.

The tabulation result receiving unit 82 is a part that receives a tabulation result generated by performing analysis processing on the agenda that is shared information from a server using a plurality of write data, and displays the received tabulation result on a display. Alternatively, the aggregation result may be printed by a printer (not shown) as necessary.
As will be described later, the tabulation results are preferably displayed in a diagram that is easy to understand visually. For example, it is preferable to display the results in a tree diagram, a fishbone diagram, or the like. Further, as shown in FIG. 32, the current automatic classification / aggregation status may be displayed so that the entire drafting status of all participants can be grasped.

The above is the main functional block of the terminal, but the function realized by the control unit 71 is not limited to this. You may provide the information output part which prints a total result.
Since these functions are mainly realized by software, a program for executing other functions is stored in the storage unit 61 as necessary, and the CPU organically operates the hardware based on the program. The function may be executed.
In addition, the program may be provided in a fixed storage in a ROM or the like in advance, but may be stored in a rewritable storage device such as a hard disk for subsequent deletion, addition, change, update, etc. It may be provided by a recording medium such as a CD or a DVD, or may be downloaded from a server or the like via a network.

<Server configuration>
FIG. 3 is a block diagram showing the configuration of an embodiment of the server according to the present invention.
The server 1 mainly includes an input unit 101, a display unit 111, a communication unit 121, an authentication unit 131, a storage unit 141, and a control unit 161.

The input unit 101 is a part for inputting various types of information, and includes a keyboard 102, a mouse 103, and an input processing unit 104 that converts an input from these input devices into a signal that can be transmitted to the control unit 161. .
The display unit 111 includes a display 112 such as an LCD or a CRT, and a display processing unit 113 that generates a display signal to be displayed on the display.
However, when the server 1 is operated completely unattended, the input unit and the display unit may not be provided.

The communication unit 121 is a part that transmits / receives data to / from the terminal TE via the network. Like the terminal, the communication unit 121 performs data communication using a predetermined communication protocol, and transmits / receives information to / from a predetermined standard (for example, AES 3DES etc.) and the communication encryption part 122 and the communication decoding part 123 which are encrypted.
Similar to the terminal TE, the authentication unit 131 is a part that identifies a user and performs login authentication to the terminal and the information sharing system.

The storage unit 141 stores various data used in processing executed by the server, and includes user information 142, an agenda 143 that is shared information, write data 144 transmitted from the terminal, and aggregation result data 145. The language processing database 146 and the character recognition database 147 are stored.
The language processing database 146 and the character recognition database 147 are used when recognizing handwritten input writing data and converting it into character string data.

The user information 142 is information for identifying the user of the terminal as described above, and includes, for example, data (U1 to U5) as shown in FIG. The data (U1 to U3) among them are registered in advance in the server. The connection state U4 is information for identifying whether the user is currently logged in or logged off. The terminal state U5 is information indicating in which mode (registration mode or conference mode) the user is activated after logging in.
Also, when a user performs a login operation on a certain terminal, a user name, a login name, and a password are input on the terminal, and these pieces of information are transmitted to the server as login information and stored in the storage unit of the server. When all the user names U1, login name U2, and password U3 in the stored user information 142 are matched and the login information is matched, the login is permitted.
Here, in consideration of confidentiality and confidentiality, it is desirable that the user name U1, the login name U2, and the password U3 are encrypted.

The agenda item 143 is data created and transmitted by the terminal in the registration mode as described above, and is composed of, for example, files (f1, f2) as shown in FIG.
The file (f1) indicates an agenda source file name, and the file (f2) indicates an actual agenda image conversion file group associated with the original file name.
Here, the agenda with the original file name “Agenda 001.doc” consists of 8 image conversion files (a01.jpg to a08.jpg), and the agenda with the original file name “Agenda 002.pdf” has 6 It shows that it consists of image conversion files (b01.jpg to b06.jpg). In addition, the original file of the agenda sent from the terminal may be stored in the server.
The write data 144 is self-written data 62-2 input at the terminal in the conference mode, and is stored as data associated with the agenda and the layer structure.

FIG. 5 shows an explanatory diagram of one embodiment of the write data.
FIG. 5A shows an example of the write data 144 input by the participant 1, and the write data a1, the handwritten character recognition result (text) a2, and the write data are associated with each other. The image conversion file a3 (f2), the agenda source file name a4 (f1), and the login name a5 (U2) are stored in association with each other.
Here, the write data “a01_01.dat” indicates a file of information input at the terminal in the conference mode, and the handwritten character recognition result (text) “ume” indicates that the input write data is handwritten. If it is a character, character string data that is a result of character recognition of the handwritten character is shown. Alternatively, character string data input with a keyboard or the like is stored as text data as it is.

In FIG. 5A, the character handwritten as the first write data “a01 — 01.dat” for “Agenda 001.doc” is “Plum”.
In addition, the character handwritten as the third writing data “b01_03.dat” for “Agenda 002.pdf” is “Persian”.
FIG. 5B shows an example of the write data 144 input by another participant 2, and similarly, the write data a1, the handwritten character recognition result (text) a2, and the image conversion file. a3 (f2), agenda file name a4 (f1), and login name a5 (U2) are stored in association with each other.

Here, for example, “a01_01.dat” of the write data in FIG. 5B indicates a file of information input by the participant 2 at the terminal in the conference mode, and the result of recognizing the handwritten character (text) “Sakura” indicates character string data that is a result of character recognition of the handwritten character when the input writing data is a handwritten character.
Here, it is assumed that the agenda described in “Agenda 001.doc” is “Please enter a flower you can come up with”. At this time, since the participant inputs the names of a plurality of flowers by handwriting, the input order is not limited.
In FIG. 5A, the participant 1 inputs four types of flowers, “ume”, “peach”, “sakura”, and “tulip” in this order.
In FIG. 5B, the participant 2 inputs four types of flowers, “sakura”, “ume”, “sunflower”, and “hydrangea” in this order.
Furthermore, if the agenda listed in “Agenda 002.pdf” is “Please enter the cat you can come up with”, the two participants will be shown in Fig. 5 (a) and Fig. 5 (b), respectively. As shown, four types of cats are written.
As will be described later, the server compares the plurality of write data with each other and automatically performs classification and aggregation processing.

In FIG. 5, for each of two agenda items, the written data input by two participants is compared with the respective handwritten character recognition results (texts), and if there is a match, they belong to the same group. If they do not match, they are classified into another group.
For example, with respect to “Agenda 001.doc”, four written data (ume, peach, cherry, tulip) input by participant 1 and four written data (cherry, plum, (Sunflower and Hydrangea) are compared, and classification processing and aggregation processing are performed.
In this case, since the same “cherry blossom” is input by both persons, it belongs to the same group, and the total number of flowers “sakura” is “2”.
Since the other flowers do not overlap, they are classified as different groups, and the total number is set to “1”.
Similarly, for “Agenda 002.pdf”, the names of the four cats entered are compared, and both “Persia” and “Siam” are written, so the total number is “2”. "
The other cats are classified into different groups, and the total number is “1”.

As described above, for each corresponding agenda, a plurality of write data input by a plurality of participants are compared, and automatic tabulation is performed.
FIG. 6 shows an explanatory diagram of an example of the result of the classification and aggregation processing (aggregation result data 145) as described above. Here, the tabulation results for “Agenda 001.doc” which is the agenda source file name c1 are shown. Three participants (tarou, saburou, jirou) input the write data.
As a result (c2) of comparison of written data by a plurality of participants, a recognition result c21 of handwritten characters, and a word c22 determined as a synonym (similar data) belonging to the same group from a result of analysis by language processing Are extracted and classified.
For example, with respect to “ume” in the handwritten character recognition result c21, two character strings “ume” and “ume” are also recognized as synonyms.
Further, as the classification / aggregation result c3, the same data number c31, the user name c32 that inputs the same data, the similar data number c33, and the user name c34 that inputs the similar data are shown. Here, the same data count c31 is a value (total count) obtained by totaling the number of identical write data. The number of similar data c33 is a value obtained by tabulating the number of write data determined to be within a predetermined similar range, that is, the number of write data determined to be synonyms.

FIG. 7 is a correlation diagram showing the interrelationship of the write data (flower names) input by three participants in order to obtain the aggregation result data shown in FIG.
For example, in FIG. 7, two participants have entered the same data “Plum” and “Sakura”, and another participant has entered “Sakura” similar to “Sakura”. Yes.

In FIG. 6, since the number of the same data of “ume” is 2, it can be seen that two participants (user names: tarou, saburou) input the same flower.
In addition, for “Sakura”, the number of the same data is 2, so it can be seen that two participants (tarou, saburou) input the same flower, and since the number of similar data is 3, “Sakura” It can be seen that three participants (tarou, saburou, jirou) input the same semantically flowers, including “Sakura” or “Sakura”, which are synonyms.
The aggregation result data shown in FIG. 6 creates a tree diagram (see FIG. 8) and a fishbone diagram (see FIG. 9) on the basis of the information c3 of the classification / aggregation result, and visually for the user. It is preferable to display in an easily understandable format.
FIG. 8 is a tree diagram of the write data correlation diagram of FIG. 7, and FIG. 9 is a fishbone diagram of the write data correlation diagram of FIG.

In addition to this, the storage unit 141 also stores programs necessary for executing each function of the server.
As the storage unit 141, a recording medium such as a ROM, a RAM, a hard disk, a CD, or a DVD is used.

The control unit 161 is a part corresponding to a microcomputer including a CPU, a ROM, a RAM, an I / O controller, a timer, and the like. The CPU performs various hardware operations based on a program stored in the storage unit 141. Each function of the server is realized by operating the server.
In FIG. 3, ten functions are shown in the control unit 161 from the login request receiving unit 162 to the totaling result transmitting unit 171, but the realized functions are not limited to this.

In FIG. 3, a login request receiving unit 162 is a part that receives login request information sent from a terminal.
The user verification unit 163 receives the user information of the user sent from the terminal at the time of login, compares the received user information with the user information stored in advance in the storage unit 141 of the server, and matches. It is a part to check whether or not something exists. If there is a match, the user verification is successful. If there is no match, it is determined that the user verification has failed.
If the user verification is successful, a notification indicating that the login is approved is transmitted to the terminal, and the connection state U4 corresponding to the user of the terminal is set to “login”.

The terminal mode receiving unit 164 is a part that receives terminal mode information sent from the terminal. In the terminal, the “terminal mode” is determined by the user's selection operation and transmitted to the server.
As described above, the terminal mode includes “registration mode” and “conference mode”.
In addition, after receiving the “terminal mode”, the server transmits an approval notification indicating that the terminal mode has been accepted to the terminal, and sets the terminal state U5 for the user of the terminal to the received mode. .

The logoff request receiving unit 165 is a part that receives logoff request information sent from the terminal.
The logoff permission unit 166 confirms the received logoff request information, and when the content is valid as compared with the user information 142 of the storage unit 141, transmits information for permitting logoff to the terminal. It is a part to do.

The agenda registration unit 167 is a part that causes the storage unit 141 to store the agenda transmitted from the terminal in the registration mode.
Here, the received agenda is subjected to image conversion as described above, and then stored in the state of an image conversion file. After storing, a registration completion notification indicating that the registration is completed is transmitted to the terminal.
The write data registration unit 168 is a part that causes the storage unit 141 to store the write data transmitted from the terminal in the conference mode. Here, as the write data 144, information as shown in FIG. 5 is stored.

  The shared information distribution unit 169 is a part that distributes shared information from the server to the information terminal. The shared information distributed from the server to the terminal always includes the agenda and may include other person-written data.

The automatic counting unit 170 is a part that performs analysis processing on the shared information using a plurality of write data sent from the terminal in the conference mode, and generates a counting result.
For example, by comparing a plurality of write data input by different participants and transmitted from different terminals, an analysis process mainly including classification and aggregation is performed.
The aggregation result transmission unit 171 is a part that transmits the aggregation result 145 (for example, FIG. 6) generated by the automatic aggregation unit 170 to the terminal of the participant who has requested the aggregation.
The aggregation result data 145 may be transmitted as data information as shown in FIG. 6, or may be transmitted after being converted into a diagram format as shown in FIG. 8 or 9 on the server side.

<Description of information communication between server and information terminal>
Hereinafter, processing contents of an embodiment of information communication performed between the server and the information terminal of the present invention will be described.
(1) Terminal Startup Process FIG. 10 shows a flowchart of the terminal startup process.
In step S101 in FIG. 10, when the user of the terminal performs an operation corresponding to login, the login request unit 72 of the terminal transmits information indicating a login request to the server (login request processing).
FIG. 25 shows an example of a display screen for performing a login operation.
In the display screen of FIG. 25, the user inputs a name, a login name, and a password. Here, the same data as that previously registered in the server is input as the login name and password. Although the name shows what is input with handwritten characters, the characters may be input using a keyboard or the like. After such an input, an operation input that means a login request is performed, whereby the login request is transmitted to the server.
In step S <b> 102, the login request unit 72 confirms whether or not a notification for approving login is received from the server (login approval receiving process).

If the login approval information is received, terminal mode selection processing is executed in step S103.
In the terminal mode selection process, a mode selection screen as shown in FIG. 26 is displayed, and the user is allowed to input any of the three items with a pen.
In FIG. 26, it is assumed that any one of “agenda registration”, “conference start”, and “logout” can be selected.
Here, if the area displayed as “Agenda Registration” is selected and input with a pen, it is determined that “Registration Mode” has been selected.
Further, if an area displayed as “Conference start” is selected and input with a pen, it is determined that “Conference mode” is selected.

If the selected mode is the registration mode in step S104, the process proceeds to step S105. If the selected mode is the conference mode, the process proceeds to step S106.
In step S105, the registration mode activation unit 76 activates the terminal as a terminal in the registration mode.
FIG. 27 shows an example of the initial screen when the registration mode is started.
On this initial screen, the agenda can be input as will be described later.

In step S106, the conference mode activation unit 77 activates the terminal as a conference mode terminal.
The terminal activated in the conference mode receives shared information including the agenda from the server. Information requesting distribution of the agenda may be transmitted from the terminal to the server.
The agenda received by distribution from the server is displayed on the display by a predetermined operation of the user of the terminal.
In either case after step S105 or step S106, the process proceeds to step S107, and information on the selected terminal mode is transmitted to the server.

In step S108, the server waits for a notification for approving the terminal mode from the server. If this approval notification is received, the process ends. On the other hand, if it cannot be received, the process returns to step S107, and the terminal mode information is retransmitted at regular intervals, for example.
After that, the participant in the conference mode looks at the agenda displayed on the display and inputs his / her writing data. At this time, the input write data is input to the participant as if it were written on the agenda page itself, but the written information is stored as a data file separate from the agenda.
As described above, the terminal in the conference mode can display the agenda and input the write data.

  FIG. 31 shows a state in which the participant 2 inputs the writing data “peach” by handwriting with a pen. Further, in FIG. 31, as shared information received from the server, the agenda page (please enter a flower you can come up with) and the written data of participant 1 that has already been written (handwritten input characters of cherry blossoms) The image conversion file) page is superimposed and displayed. The newly input “peach” is stored as data written on another page.

Participant 2 hand-draws the flower he / she came up with at the writing data input position in the empty area on the screen on which the shared information including the agenda and writing data (cherry tree) is displayed. Enter it.
In the case of FIG. 31, the participant 2 writes the name of the flower that he came up with while looking at the letters “sakura” written by the participant 1. At this time, the participant may write a flower different from “Cherry Blossom”, or may write the same “Cherry Blossom” flower if he / she cannot think of it.
Alternatively, when trying to input “peach” by handwriting, if you do not know the kanji, you may input it by handwriting with hiragana, such as “Momo” or “Momo”. As described above, both the case where the Chinese character “peach” is input and the case where “peach” or “peach” is input are treated as the same semantically.

FIG. 12 shows a flowchart of user management processing in the server.
In step S <b> 1, the login request receiving unit 162 of the server confirms whether or not the login request information transmitted from the terminal is received (login request receiving process).

When the login request information is received, the process proceeds to step S2, where the user verification unit 163 acquires the user information included in the login request information and compares it with the user information 142 stored in the storage unit 141 of the server. Check terminal users.
When both user information corresponds, it progresses to step S3 and the user collation part 163 transmits the information which shows having approved the login of the terminal to a terminal.
In step S4, it is confirmed whether or not terminal mode information is received from the terminal to which the server has transmitted login approval (terminal mode reception process).
When the terminal mode information is received, in step S5, terminal mode approval information indicating that the terminal mode information has been received is transmitted to the terminal (terminal mode approval process).

FIG. 20 shows an explanatory diagram of an embodiment of a communication sequence between the terminal and the server executed in response to this terminal activation process.
By executing a series of processes as shown in FIG. 10 and FIG. 12, a notification for approving the login request and terminal mode notification from the terminal is transmitted from the server to the terminal.
Thereafter, the terminal operates as a terminal in the registration mode or the conference mode according to the selected terminal mode.

(2) Terminal Termination Processing FIG. 11 shows a flowchart of terminal termination processing.
In step S111, when the user of the terminal performs an operation corresponding to logoff, the logoff request unit 74 transmits logoff request information to the server (logoff request processing).
In step S112, it is checked whether information permitting logoff is sent from the server.
If the logoff permission information is received, the process proceeds to step S113. If not, step S111 is looped.
In step S113, the logoff processing unit 75 executes logoff processing. Here, as logoff processing, for example, processing such as termination of use of the server and the information sharing system, termination of use of the terminal, and the like are performed.

FIG. 13 shows a flowchart of terminal termination processing in the server.
In step S7, the logoff request receiving unit 165 checks whether logoff request information has been received from the terminal (logoff request receiving process).
If a logoff request is received, the process proceeds to step S8, where the logoff permission unit 166 confirms whether or not to permit the logoff, and if permitted, transmits logoff permission information to the terminal.

FIG. 21 shows an explanatory diagram of an embodiment of a communication sequence between the terminal and the server executed corresponding to the terminal termination process.
By executing a series of processes as shown in FIG. 11 and FIG. 13, in response to a logoff request from the terminal, a notification permitting logoff is transmitted from the server.
Thereafter, a log-off process is executed at the terminal, and for example, a display screen for accepting login is displayed.

(3) Agenda Transmission Process FIG. 14 shows a flowchart of the agenda transmission process in the terminal.
This process is executed by the terminal activated as the registration mode.
It is assumed that an input for selecting the “agenda registration” portion is made in a state where the display screen of FIG. 26 is displayed. At this time, for example, an initial screen for agenda registration as shown in FIG. 27 is displayed. A case where the USB memory is connected in this display state will be described below.
In step S <b> 121, the user confirms whether or not an external memory (for example, a USB memory) in which the agenda is stored is connected to the external storage IF unit 51. When it is confirmed that the USB memory is connected, the agenda transmission unit 78 checks whether or not the agenda source file exists in the USB memory.
In step S122, if the original file exists, the process proceeds to step S123. If not, the process ends.

If the original file exists, it is checked in step S123 whether or not the user has selected a file to be used among the existing original files. Here, if the original file of the agenda exists in the USB memory, the file name of the original file of the agenda is read, and the file name of the original file existing in the external recording device is changed to the external recording folder as shown in FIG. Display in the area.
That is, a screen that allows the user to select which original file is used is displayed on the display unit.

The user can select and input the original file to be used while viewing this display screen.
For example, as shown in FIG. 29, the “Agenda 001.doc” icon in the external recording folder is selected with a pen, and the agenda registration button portion is input. Thereafter, as shown in FIG. 30, the selected “Agenda 001.doc” icon is displayed in the “Conference server conversion” area to inform the user that it has been selected.
As described above, when the user inputs to select the original file, the process proceeds to step S124.
In step S124, the selected agenda is transmitted to the server.

In step S125, it is checked whether or not a notification indicating that registration of the agenda has been completed is received from the server. If this registration completion notification is received, the process proceeds to step S126.

(4) Write Data Transmission Process FIG. 16 shows a flowchart of the write data transmission process in the terminal. This process is executed by the terminal activated as the conference mode.
In step S131, when the user performs an input operation of write data using the input unit 11, the write data processing unit 79 uses the input information to create a data file of predetermined write data. Generate.

Here, the input of the write data is, for example, a write data input position that is an empty space on the screen in a state where the agenda of the received shared information or a predetermined page of the other person's write data is displayed on the display screen In addition, it is only necessary to input characters and the like by handwriting.
For example, as shown in FIG. 31, the image converted agenda and the page of participant 1's writing data are displayed, and participant 2 puts the writing data with a pen in an empty space position that can be input without overlapping. Input by handwriting. Here, “peach” is input by handwriting. As a result, self-written data including the input handwritten character information and information such as the input position is generated.
The handwritten character information input by handwriting may be converted not only as an image but also into character string data (text information) by executing a character recognition process. Further, as shown in FIG. 32, the current automatic classification / aggregation status may be displayed so that the entire drafting status of all participants can be grasped.
By displaying the other person's write data or the current automatic classification / aggregation status, it becomes possible to think of the self-written data recalled from it while referring to the other person's write data. In addition, it is possible not only to easily grasp how often the same or the same writing has been input, but also to quickly discover novel ideas devised from different viewpoints.

The generated self-written data file (self-written data 62-2) is stored in the storage unit 61. At this time, the self-written data 62-2 is stored in association with the corresponding page of the agenda 63-1.
In step S132, the write data processing unit 79 transmits the generated self-written data to the server.
In step S133, it is checked whether or not input of write data is completed. For example, it is checked whether or not an operation meaning completion of input has been performed by the user. If an operation indicating completion of input has been performed, the process proceeds to step S134; otherwise, the process returns to step S131.
In step S134, it is checked whether a notification indicating that the registration of the write data has been received from the server. If this notification is received, the process ends.

FIG. 17 shows a flowchart of write data registration processing in the server.
In step S21, the server checks whether write data has been received from the terminal. If received, the process proceeds to step S22, and if not, the process ends.
In step S <b> 22, the write data registration unit 168 registers the received write data in the storage unit 141. For example, the write data is registered as information as shown in FIG.
In step S23, when the registration is completed, the write data registration unit 168 transmits information indicating that the registration of the write data is completed to the terminal.

FIG. 23 shows an explanatory diagram of an embodiment of a communication sequence between the terminal and the server executed in correspondence with the write data transmission processing and registration processing.
By executing the series of processes shown in FIGS. 16 and 17, the created write data is transmitted to the server, and after registration with the server, information indicating that the registration is completed is transmitted to the terminal. . Thereby, the user of the terminal can know that the registration of the write data is completed.

(5) Aggregation Result Request and Reception Processing FIG. 18 shows a flowchart of the aggregation result reception processing in the terminal. This process is executed by the terminal activated as the conference mode.
For example, it is assumed that the “classification / aggregation” display portion is selected and input with a pen while the display screen of FIG. 33 is displayed.
In step S141, if the participant performs an operation for requesting aggregation at the terminal, the aggregation request unit 81 transmits information indicating the aggregation request to the server. Here, the aggregation request information is information including user information, an IP address, a terminal ID, and the like, for example.

In step S142, the tabulation result receiving unit 82 waits for the tabulation result to be sent from the server. If the tabulation result is received, the process proceeds to step S143.
In step S143, the received count result is displayed in a diagram such as FIG. 34 or FIG. 35, for example.

FIG. 19 shows a flowchart of the aggregation process in the server.
In step S41, the server checks whether or not an aggregation request sent from the terminal is received. If the aggregation request is received, the process proceeds to step S42, and if not, the process ends.
In step S42, the automatic tabulation unit 170 classifies and tabulates the received write data using the above-described tabulation method.
Aggregation result data 145 as shown in FIG. 6 is stored in the storage unit.
In step S43, the aggregation result transmission unit 171 transmits the aggregation result to the terminal that has requested the aggregation.

FIG. 24 is an explanatory diagram of an embodiment of a communication sequence between the terminal and the server executed in response to the aggregation request, the reception process, and the server aggregation process.
When the aggregation request is transmitted to the server by executing the series of processes shown in FIGS. 18 and 19, the server automatically performs the aggregation process, and the aggregation result is transmitted to the terminal that has requested the aggregation request. Is displayed. As a result, the participant who is the user of the terminal requests the aggregation immediately after the data is written, so that even if all the participants have not finished writing, the current aggregation result can be confirmed on the screen. can do.

The counting results may be printed if there is a printer connected to the terminal, or may be stored in the storage unit of the terminal if the terminal is a personal computer owned by the user, If it is not an individual personal computer, it may be stored in an external storage device (USB memory or the like) 50 connected to the external storage IF unit 51 and brought back.
Also, the aggregation request means both the end of writing and the aggregation request when the user does a specific operation that means the end of writing, rather than a specific operation that means the aggregation request. Information to be transmitted may be transmitted to the server.
