Abstract:
The present invention relates to a semantic-based search system capable of enhancing precision of searching by ranking interpretation alternatives in consideration of user preference when a plurality of interpretation alternatives are searched according to a keyword input by a user, and a search method thereof. According to the present invention, the semantic-based search system includes: a log generating unit configured to generate a common log storing knowledge corresponding to general knowledge and a user log stored by reflecting user preference; an instance analyzing unit configured to analyze vector characteristics corresponding to an instance among interpretation alternatives according to a keyword input by a user; a weight calculating unit configured to calculate weights of confidence values and cosine similarity values of interpretation alternatives including vector characteristics of the instance with respect to at least one of the common log and the user log; and an aligning unit configured to align rankings of the interpretation alternatives according to the keyword input on the basis of the calculated weights of the confidence values and the cosine similarity values. Accordingly, since interpretation alternatives according to user keyword search based on a calculation of weights of confidence values and cosine similarity values are aligned as rankings in consideration of user preference, user search satisfaction can be enhanced.
