Abstract

An information retrieval system includes an information extracting portion that extracts episodic information to be set as a cue for searching conference record information that stores contents on a conference for personal information, and an information storage portion that stores the episodic information extracted from the information extracting portion and the personal information associated with the episodic information. The personal information of a participant is searched for, personal information being obtained from the conference that a system user attended.

Claims

1. An information retrieval system comprising:

an information extracting portion that extracts episodic information to be set as a cue for searching conference record information that stores contents on a conference for personal information; and

an information storage portion that stores the episodic information extracted from the information extracting portion and the personal information associated with the episodic information,

wherein the personal information of a participant is searched for, personal information being obtained from the conference that a system user attended.

2. The information retrieval system according to claim 1, wherein the information extracting portion analyzes a pickup sound of the participant and extracts the episodic information from the pick up sound and a captured image that are associated with each other and included in the conference record information.

3. The information retrieval system according to claim 1, wherein the information extracting portion extracts a number of conversation times of the system user and the participant, as the episodic information.

4. The information retrieval system according to claim 2, wherein the information extracting portion extracts a conversation sound extracted from the pickup sound of the participant, as the episodic information.

5. The information retrieval system according to claim 2, wherein the information extracting portion extracts a conversation image extracted from the captured image of the participant, as the episodic information.

6. The information retrieval system according to claim 1, wherein the information extracting portion extracts a number of conversation time of the participant as the episodic information.

7. The information retrieval system according to claim 1, wherein the information extracting portion extracts a remark sound extracted from the pickup sound of the participant, as the episodic information.

8. The information retrieval system according to claim 2, wherein the information extracting portion extracts a remark image extracted from the captured image of the participant, as the episodic information.

9. The information retrieval system according to claim 1, wherein the information extracting portion extracts positional information of the participant, as the episodic information.

10. The information retrieval system according to claim 1, further comprising an information retrieval portion that displays the episodic information or the personal information stored in the information storage portion.

11. The information retrieval system according to claim 10, wherein the information retrieval portion displays the episodic information or the personal information stored in the information storage portion on the basis of a name included in the personal information of the participant.

12. The information retrieval system according to claim 10, wherein the information retrieval portion displays the episodic information or the personal information stored in the information storage portion on the basis of a date of the conference that the system user attended.

13. The information retrieval system according to claim 10, further comprising a forgetting level determination portion that determines a forgetting level of the system user with respect to the episodic information stored in the information storage portion,

where in the information retrieval portion displays a list of the episodic information stored in the information storage portion according to the forgetting level determined by the forgetting level determination portion, the episodic information being a search condition.
