Provided is an information retrieval system capable of efficiently discovering information that a retriever wants to know. The information retrieval system comprises: a database (12) for storing multiple pieces of information from which texts can be retrieved; an inquiry sentence acceptance unit (26) for accepting an inquiry sentence having a natural language format; an input retrieval keyword extraction unit (44) for extracting an input retrieval keyword from an inquiry sentence; a retrieval execution unit (40) for executing a retrieval process from the database by using the input retrieval keyword and a keyword related to the input retrieval keyword; and a keyword dictionary (30) in which terms are registered in association with categories.
