METHOD, APPARATUS AND COMPUTER READABLE RECORDING MEDIUM FOR SEARCH WITH EXETENSION DATA-SET OF CONCEPT KEYWORDS

摘要

PURPOSE: A search method using a concept keyword expansion data set, a device thereof, and a computer-readable recording medium thereof are provided to extract a concept keyword and a modifier by separating the concept keyword and the modifier from a search keyword. CONSTITUTION: A concept keyword mapping unit(310) maps a search keyword with a concept keyword included in concept keyword expansion data sets(332a-322n). A concept keyword expanding unit(312) expands the mapped concept keyword to concept keywords having a correlation by applying the concept keyword to the concept keyword expansion data sets. The concept keyword expansion data sets include the concept keywords and correlation information between the concept keywords. The concept keyword mapping unit analyzes morphemes of the search keyword and determines a morpheme not mapped with the mapped concept keyword among the morphemes in the search keyword as a modifier.
