Abstract

Claims (74)

1 . An information processing apparatus comprising:

circuitry configured to:

receive a request from a user which designates an expert as an information type of a collection target and a character string related to the collection target;

convert the character string to a first vector represented by distributed representation that is an expression according to a meaning contained in data to be converted;

convert a plurality of items of document data to second vectors represented by the distributed representation, respectively, the plurality of items of document data stored in one or more memories as target data including document data created or updated by a person;

calculate a similarity between the first vector and the second vectors for each of the plurality of items of document data;

extract the second vector with a similarity that satisfies a predetermined requirement;

acquire an item, corresponding to the second vector extracted, among the plurality of items of document data;

collect identification information of the person who created or updated the item acquired as corresponding to the second vector extracted; and

generate display information, the display information causing a display to display a list including the identification information of the person.

2 . The information processing apparatus of claim 1 , wherein

the circuitry is further configured to:

classify the target data based on the second vectors of the target data,

the display information indicating a classification result.

3 . The information processing apparatus of claim 2 , wherein

the circuitry is further configured to:

generate a diagram illustrating a relationship between the target data and the character string based on the classification result,

the display information including the diagram.

4 . The information processing apparatus of claim 2 , wherein

the circuitry is further configured to assign a label based on a word included in the target data, for each set of the classified target data.

5 . The information processing apparatus of claim 1 , wherein

the circuitry is configured to generate, according to the information type, the display information for displaying information on the person related to the target data, based on a similarity between the target data and the character string.

6 . The information processing apparatus of claim 1 , wherein

the circuitry is further configured to:

generate related information that associates the target data selected based on the same character string, and stores the related information in the one or more memories; and

generate, according to the information type, the display information for displaying the related information related to the target data based on a similarity between the target data and the character string.

7 . The information processing apparatus of claim 6 , wherein

the circuitry is further configured to reflect edited content of the related information to the related information stored in the one or more memories.

8 . The information processing apparatus of claim 6 , wherein

the circuitry is further configured to generate, for each target data, display information including information that guides the user to the related information related to the target data.

9 . The information processing apparatus of claim 1 , wherein

the display information includes information indicating that an access to the target data is authorized or unauthorized.

10 . The information processing apparatus of claim 1 , wherein

the information related to the target data further includes an image or video.

11 . The information processing apparatus of claim 1 , wherein

in a case in which the information related to the target data is information regarding a meeting using the target data, the circuitry is configured to generate the display information to include information that allows access to at least one of video or audio related to the meeting.

12 . The information processing apparatus of claim 1 , wherein

the circuitry is configured to search for the target data from the plurality of items of data based on the first vector and the second vectors.

13 . The information processing apparatus of claim 1 , wherein

the plurality of items of data are converted to the second vectors in advance before receiving the character string.

14 . The information processing apparatus of claim 1 , wherein

the information type further includes a workspace and a document.

15 . The information processing apparatus of claim 1 , wherein

the circuitry is further configured to:

transmit the display information to a user terminal connected to the information processing apparatus; and

cause the user terminal to display information sorted by the similarity so that the user has access to the sorted information.

16 . The information processing apparatus of claim 1 , wherein

the circuitry is further configured to:

acquire employee information of the person from an employee information storage based on the identification information of the person, the employee information including a name and contact information of the person, and a department in a company to which the person belongs; and

generate the display information to include the employee information.

17 . The information processing apparatus of claim 1 , wherein

the circuitry is further configured to:

acquire employee information of the user and the person from an employee information storage; and

in a case in which the user and the person belong to a company, evaluate accessibility from the user to the person based on an index indicating a distance between a department in the company to which the user belongs and a department in the company to which the person belongs.

18 . An information processing system comprising:

circuitry configured to:

receive a request from a user which designates an expert as an information type of a collection target and a character string related to the collection target;

convert the character string to a first vector represented by distributed representation that is an expression according to a meaning contained in data to be converted;

convert a plurality of items of document data to second vectors represented by the distributed representation, respectively, the plurality of items of document data stored in one or more memories as target data including document data created or updated by a person;

calculate a similarity between the first vector and the second vectors for each of the plurality of items of document data;

extract the second vector with a similarity that satisfies a predetermined requirement;

acquire an item, corresponding to the second vector extracted, among the plurality of items of document data;

collect identification information of the person who created or updated the item acquired as corresponding to the second vector extracted; and

generate display information, the display information causing a display to display a list including the identification information of the person.

19 . An information processing method, comprising:

receiving a request from a user which designates an expert as an information type of a collection target and a character string related to the collection target;

converting the character string to a first vector represented by distributed representation that is an expression according to a meaning contained in data to be converted;

converting a plurality of items of document data to second vectors represented by the distributed representation, respectively, the plurality of items of document data stored in one or more memories as target data including document data created or updated by a person;

calculating a similarity between the first vector and the second vectors for each of the plurality of items of document data;

extracting the second vector with a similarity that satisfies a predetermined requirement;
