Information collecting apparatus, method, and program

摘要

An event collecting destination site registering unit registers event collecting destination sites for detecting the presence or absence of an event which occurred on the network or in the real world. An information collecting destination site registering unit registers information collecting destination sites for collecting documents including data such as text, image, audio sound, and the like. An event detecting unit obtains information from the registered event collecting destination sites, discriminates an updating area of the obtained information, and detects the occurrence of the event. A keyword extracting unit extracts a keyword from the updating area of the information detected by the event detecting unit. An information searching unit searches the documents in the registered information collecting destination sites by using the keyword extracted by the keyword extracting unit. An information notifying unit notifies the user of a search result.
