Abstract
Highly accurate document search, especially intellectual property-related document search, is achieved with a simple input method. A processing portion has a function of generating text analysis data from text data input to an input portion; a function of extracting a search word from words included in the text analysis data; and a function of generating first search data from the search word on the basis of weight dictionary data and thesaurus data. A memory portion stores second search data generated when the first search data is modified by a user. The processing portion updates the thesaurus data in accordance with the second search data.
Claims13
A semiconductor device comprising:
- a processor;
- and
- a memory portion configured to store search data,
- wherein the processor is configured to perform a document search comprising the steps of:
- generating weight dictionary data and thesaurus data on the basis of a plurality of pieces of reference document data stored in a database;
- generating text analysis data;
- extracting a search word or a plurality of search words from words included in the text analysis data;
- generating first search data from the search word or the plurality of search words on the basis of the weight dictionary data and the thesaurus data;
- outputting the first search data to a display device;
- and
- displaying the first search data on the display device to enable modification of a value of weight data of the first search data and generation of second search data based on the modification.
