Information processing system and method that selects an appropriate information retrieval system based on a context in which a user makes a request for retrieval

摘要

An information retrieval processing system includes a search question input unit to receive a search question of a user. A context acquisition unit then acquires a context from a context action correspondence table that corresponds to the received search question. An action which corresponds to the acquired context is then used to select an information retrieval system from a plurality of information retrieval systems. A history recording unit records a history of the questions received by the search question input interface unit such that the recorded history is used to select the information retrieval system. Accordingly, the retrieval system automatically reads the context into which the user will attempt to input the information and automatically select an information retrieval system from among the plurality of information retrieval systems.
