ASSOCIATED INFORMATION SEARCH SYSTEM AND ASSOCIATED INFORMATION SEARCH METHOD

摘要

A data processing device (1) includes: an input unit (11) which inputs text data in which an unknown word whose meaning is unknown to a user or a known word which is known to a user is specified for the entire text; an unknown word classification unit (12) which classifies the unknown words according to the input text data; an associated information search unit (13) which searches for associated information associated with unknown words according to the unknown words classification result; and an associated information presentation unit (14) which presents searched associated information. Thus, without requiring a high cost, it is possible to switch the search object and modify the presentation method of associated information on the search result according to the type of the unknown words.
