Yan Chen, Long Jianxun · Jisuanji gongcheng · 2011
Different from the widely used automatic abstraction algorithm based on statistical learning method,this paper proposes an automatic abstraction algorithm based on Explicit Semantic Analysis(ESA) to analyze the meaning of words and document fragments in a concept space built with knowledge-intensive resources such as Wikipedia.Experimental result shows that,compared with traditional algorithm,it reaches better accuracy and higher information coverage rate while with less sentences.
