Abstract: An abnormality determination device obtains a moving image of a monitored area from a camera. The abnormality determination device extracts, from the moving image, a plurality of still images that continues with time and identifies an object (automobile) that moves or changes with reference to the plurality of still images. The abnormality determination device analyzes operation modes of a plurality of objects to determine whether an abnormal event such as dangerous driving occurs, and warns an automobile and so on when detecting the dangerous driving.

Abstract: A communication system is provided that is capable of flexibly dealing with conversations among agents. An agent includes a software part which performs operations that represent the functions of a human ear and a mouth. In generating a conversation, an agent communication language, which is similar to a human conversation, is prepared and sent to a conversation part as a message packet. The conversation part then generates a plurality of conversation threads one for each unit of conversation and converse with a plurality of nodes in parallel and asynchronously. On the other hand, in another node which receives the message packet, a protocol manager receives the data (message packet) from a network and passes it to the conversation part. The conversation part understands the message packet and executes the content. In the preferred embodiment of this invention, the conversation part moves to other places along with a mobile agent.

Abstract: A communication system is provided which, upon communication, is capable of making a suitable response by using interpretation execution parts which conform to the background concepts and vocabularies of a conversation. A flexible and smooth information exchange and cooperation are realized among, and between, agents and an existing system by dynamically allocating suitable interpretation execution parts which include an interpreter in conformance to a variety of agent communication languages, content describing languages and ontologies. The agent communication system in a preferred embodiment of this invention is provided with an interpretation execution part control function that scans a directory of interpretation parts such as conversation content monitoring parts, interpreters and translators, upon the time of execution start or during execution, and forms and maintains an interpretation execution part table that defines what interpretation execution parts exist.

Abstract: The broker agent 121,123 inquires a facilitator agent 110 to recognize a service provider agent 131,133 which is involved in its own job. The broker agent 121, upon receiving from a regular agent a message packet indicating a request for mediation of a job, analyzes the message packet to judge the outline of the requested job and applies certain conversion to the request message for sending it to the service provider agent which is relevant to the request. The broker agent 121 receives a reply from the service provider agent 131,133 and sends it to the regular agent after applying certain conversion.

Abstract: A communication system is provided that is capable of flexibly dealing with conversations among agents. An agent (201) includes a software part (200) which performs operations that represent the functions of a human ear and a mouth. In generating a conversation, an agent communication language, which is similar to a human conversation, is prepared and sent to a conversation part (200) as a message packet. The conversation part (200) then generates a plurality of conversation threads one for each unit of conversation and converse with a plurality of nodes in parallel and asynchronously. On the other hand, in another node which receives the message packet, a protocol manager (230) receives the data (message packet) from a network and passes it to the conversation part (200). The conversation part (200) understands the message packet and executes the content. In the preferred embodiment of this invention, the conversation part (200) moves to other places along with a mobile agent.
