EPISODIC AND SEMANTIC MEMORY BASED REMEMBRANCE AGENT MODELING METHOD AND SYSTEM FOR VIRTUAL COMPANIONS
First Claim
1. A computer system, comprising:
- a computer processor;
at least one sensor for determining at least one characteristic of the user;
at least one information transmission device for transmitting information to the user; and
a data storage device, the data storage device storing;
(i) an episodic memory database of documents, each document representing a respective previous episode experienced by the user;
(ii) a semantic memory database indicative of the incidence in the previous episodes of each of a plurality of predefined concepts C; and
(iii) program instructions operative by the processor to cause the processor to;
(a) use data obtained using the at least one sensor to classify a current situation according to the plurality of predefined concepts C, to derive a current concept set which is one or more of said predefined concepts C, the current concept set being those of the predefined concepts C which are relevant to the current situation; and
(b) use the current concept set, the episodic memory and the semantic memory to obtain additional information relevant to the current situation, and transmit at least some of the additional information to the user using the at least one information transmission device.

Abstract
A remembrance agent is proposed, to be hosted on a wearable computer. The remembrance agent employs a first database (WK) of knowledge about the world in the form of concept maps. Events (“episodes”) experienced by a user are each classified as relating to one or more of the concepts in WK. The episodes are used to produce a second database (episodic memory, EM), and the classification is also used to update a third database (semantic memory, SM) organised using the concepts. The semantic memory thus summarizes the user'"'"'s interaction with the concepts during the episodes. A current situation of the user is classified according to the concepts, and the classification is used, with the EM and SM, to provide to the user information relevant to the current situation.

4. A method of obtaining information relevant to a current situation, the method being performed by a computer system comprising:
-
a computer processor; at least one sensor for determining at least one characteristic of the user; at least one data input device for receiving input from the user; at least one information transmission device for transmitting information to the user; a data storage device, the data storage device storing; (i) an episodic memory database of documents, each document representing a respective previous episode experienced by the user; (ii) a semantic memory database indicative of the incidence in the previous episodes of each of a plurality of predefined concepts C; the method comprising; (a) using data obtained using the at least one sensor to classify the current situation according to the plurality of predefined concepts C, to derive a current concept set which is one or more of said predefined concepts C, the current concept set being those of the predefined concepts C which are relevant to the current situation; and (b) using the current concept set, the episodic memory and the semantic memory to obtain additional data relevant to the current situation. - View Dependent Claims (5, 6)
