  • Summarizing System ABISYS based on semantic analysis

抄録

We developed a summarizing system ABISYS based on the output of semantic analysis system SAGE. ABISYS extracts important words from an ariticle and generates summary sentences according to the word meanings and the deep cases among the words in the output from SAGE. In this paper, we define five kinds of scores to evaluate the importance of a word respectively on repetition information, context information, position information, opinion word information and topic-focus information. We first calculate the above scores for each substantive and reflect them in a five-dimensional space. Then the probability of each substantive to be important is calculated using SVM. Finally, we complement the indispensable cases for verbs and the sahen nouns that have been selected as important words, and use them as the summary element words to generate legible Japanese sentences. We carried out a subjectivity evaluation for our system output by refering to the summaries made by human. In comparison with the subjectivity evaluations made for other summarizing systems, we found that the point of legibility was on a par with other systems, while the point of content covering was much better. And 95% of the summary sentences generated by ABISYS were acknowledged as correct Japanese sentences.
