Description and Analysis of Topic-oriented Information Extraction Requirement
Qiang Jian · Jisuanji gongcheng · 2012
In the construction of topic oriented information extraction system,extraction requirements are core of all extraction tasks.For natural language description of extraction requirements leads to a computational resource waste and extraction efficiency issues,a formal definition is proposed on the requirements of topic-oriented information extraction.On this basis,it researches on extracting relations between requirements.The reduced requirements set splitting method structural equivalences reduced requirements set,eliminate the extraction redundancy between requirements.Experimental results prove the equivalence of reduced requirements set can improve operating efficiency of the extraction tasks.
