Abstract

A personal-connection analysis and search method includes the steps of extracting a word from a text used in communications, accumulating the number of times of appearing the word as a communication flow, generating communication networks in an organization, extracting communication cores having a high density communication from the communication networks, calculating a communication ratio as a communication core formal degree between two constituent members having a ladder-connection relationship with respect to total communications in the communication core, and calculating a ratio of formal communication flow as a communication formal degree between the two constituent members with respect to total communication flows between the two constituent members, thereby quantifying a index for judging whether communications in an organization of the enterprise are strongly relevant to a business operation.

Claims

1. A personal-connection analysis and search sever connected with a plurality of terminals through a network, comprising:

a communication-log data storage unit that stores log data of an electronic communication implemented by using the plurality of terminals in an organization; and

a personal-connection network analysis unit that generates a keyword network, for every word, representing a relationship between constituent members in the organization communicated by using the word extracted from the log data stored in the communication-log data storage unit;

generates a communication network synthesized over plural words, each of which corresponds to the generated keyword network;

extracts a communication core as a set of the constituent members who have large communication flows with each other, with respect to a combination of specific words or words, from the generated communication network and the keyword network; and

calculates a core formal degree representing an organization consistence degree of the communication core by using the communication core and ladder-connection information representing a relationship, as an official organization, between the constituent members in the organization.

2. The server according to claim 1, further comprising a personal-connection data generation unit that calculates a communication formal degree as a formal degree of a relationship between the two constituent members from the core formal degree, the keyword network and the communication network, when two constituent members belong to the communication core of any of the words.

3. The server according to claim 2, as to two constituent members input, wherein a group of constituent members each having a communication history is searched for a relationship between the two constituent members from the log data of the communication and relationships are combined with each other;

a path is detected as an indirect connection between the two constituent members through a different constituent member;

the communication formal degree between the respective constituent members included in the path is added to calculate a path formal degree obtained from an added value divided by number of paths.

4. The server according to claim 1, wherein the communication core and its core formal degree thereof for combination of specific words or words input are outputted.

5. The server according to claim 2, wherein the communication formal degree calculated for the two constituent members input is outputted.

6. The server according to claim 2, wherein a path and its path formal degree calculated for the two constituent members input are outputted.

7. A personal-connection analysis and search program that is computer readable and executable in a personal-connection analysis and search server connected with a plurality of terminals through a network, enabling an arithmetic unit in the personal-connection analysis and search server to execute the steps of:

a first step of reading out log data of an electronic communication implemented by using the plurality of terminals in an organization, from a storage unit of the personal-connection analysis and search server or an accessible storage unit through the network;

a second step of generating a keyword network, for every word, representing a relationship between constituent members in the organization communicated by using the word extracted from the log data;

a third step of generating a communication network synthesized over plural words, each of which corresponds to the generated keyword network; and

a fourth step of extracting a communication core having large communication flows, with respect to a combination of specific words or words, from the generated communication network and the keyword network, and calculating a core formal degree representing an organization consistence degree of the communication core by using the communication core and ladder-connection information representing a relationship, as an official organization, between the constituent members in the organization.

8. The program according to claim 7, enabling the arithmetic unit in the personal-connection analysis and search server to execute a fifth step of calculating a communication formal degree, as a formal degree of a relationship between two constituent members from the core formal degree, the keyword network and communication network.

9. The program according to claim 7, enabling the arithmetic unit of the personal-connection analysis and search server to execute the steps of:

a sixth step of searching, as to two constituent members input, a group of constituent members each having a communication history for a relationship between the two constituent members from the log data of the communication, combining relationships with each other, and detecting a path as an indirect connection between the two constituent members through a different constituent member; and

a seventh step of adding the communication formal degree between the respective constituent members included in the path to calculate a path formal degree obtained from an added value divided by number of paths.

10. The program according to claim 7, enabling the arithmetic unit in the personal-connection analysis and search server to execute a eighth step of outputting the communication core and its core formal degree thereof for combination of specific words or words input.

11. The program according to claim 8, enabling the arithmetic unit in the personal-connection analysis and search server to execute a ninth step of outputting the communication formal degree calculated for the two constituent members input.

12. The program according to claim 9, enabling the arithmetic unit in the personal-connection analysis and search server to execute a tenth step of outputting a path and its path formal degree calculated for the two constituent members input.
