An information searching apparatus stores, in a character-string accumulating unit, first character strings in correspondence with second character strings while classifying each of the second character strings according to an attribute thereof. The information searching apparatus further stores, in a storage unit, the attributes in correspondence with specified information each of which is specified based on at least one of the corresponding first character string and the containing document. The information searching apparatus obtains specified information based on at least one of a first character string and a document that contains the first character string and extracts, from the storage unit, the attributes. The information searching apparatus then extracts, from the character-string accumulating unit, one of the second character strings.
