APPARATUS AND METHOD FOR STAGE JUDGEMENT USING OF TECHNOLOGY LIFE CYCLE

Stage determination apparatus including storage and processor includes: bibliographic database integrating heterogeneous resources; feature-set creation module calculating feature values of predefined features by searching the bibliographic database, and creating feature-set of each technology using the feature values, for technologies on technology lifecycle; answer-feature-set creation module calculating common feature value of feature sets of technologies belonging to the same stage in the technology lifecycle and creating answer-feature-set of each stage; stage determination module that, if technology is inputted, acquires feature values and creates feature-set for predefined features by searching the bibliographic database for the technology, compares corresponding feature value in the feature-set of the technology with feature value according to feature selection flow in previous decision tree according to the feature selection flow, and determines a stage having feature value finally selected according to the feature selection flow as a stage where the technology belongs to in the technology lifecycle.
