Abstract  

Extracting keywords directly from a single document cannot satisfy the precision requirements of keyphrase extraction, and the existing methods for keyphrase extraction based on neighbor information are time-consuming. In this paper, common author relations in research papers are utilized to build a neighbor network, and neighbor network information as well as document content is used to extract keyphrases. Based on those, high frequency pairs of phrase co-occurrence in domain are incorporated to further acquire high-quality keyphrases. Experimental results demonstrate that the proposed method is more computationally efficient than the existing methods.
