#This application claims the benefit of Korean Patent Application No. 10-2006-0029487, filed on Mar. 31, 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entity.

#1. Field

#The present invention relates to a method of performing a morpheme analysis, and particularly, to a phrase analysis for identifying a key term from a phrase.

#The above and other aspects and advantages of the present invention will become apparent and more readily appreciated from the following detailed description, taken in conjunction with the accompanying drawings of which:

#FIG. 1 illustrates an example of local information search using an exemplary morpheme analysis method;

#FIG. 2 is a flowchart illustrating a method of performing a morpheme analysis using additional information according to an exemplary embodiment of the present invention;

#Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The exemplary embodiments are described below by referring to the figures.

#In certain embodiments, a morpheme analysis will be discussed as an example of the phrase analysis. FIG. 2 is a flowchart illustrating a method of performing a phrase or morpheme analysis using additional or associated information according to an exemplary embodiment of the present invention. In operation S210, a morpheme analyzer using additional information acquires a morpheme analysis target and additional information associated with the morpheme analysis target, from search index data. In this instance, the morpheme analysis target may correspond to a search morpheme analysis target which is outputted from a search engine.

#In operation S220, the morpheme analyzer creates a key based on the additional information. In this instance, as shown in FIG. 2, operations S221 and S224 may be included in operation S220, and then performed. Also, the additional information may include category or type of business information and address information associated with the morpheme analysis target. Also, the morpheme analyzer may include a part of a speech tagger which selects only one most probable result from a plurality of morpheme analysis results. In operation S221, the morpheme analyzer creates a plurality of keys by performing the morpheme analysis for each of information included in the additional information. In this instance, as shown in FIG. 2, operations S222 and S223 may be included in operation S221 and performed.
