Keyphrase extraction based on topic relevance and term association is a publication by Decong Li, Sujian Li, Wenjie Li, Congyun Gu, Yun Li.


[edit] Abstract

Keyphrases are concise representation of documents and usually are extracted directly from the original text. This paper proposes a novel approach to extract keyphrases. This method proposes two metrics, named topic relevance and term association respectively, for determining whether a term is a keyphrase. Using Wikipedia knowledge and betweenness computation, we compute these two metrics and combine them to extract important phrases from the text. Experimental results show the effectiveness of the proposed approach for keyphrases extaction.

[edit] Research questions

"In this paper, with the help of Wikipedia knowledge,we construct a semantic graph, based on which topic relevance and term associationq qre combined to extract keyphrases."

[edit] Conclusion

"The keyphrase extraction approach proposed in this paper performs better in comparison to three other approaches."

[edit] Comments

"Wikipedia pages; documents

The Wikipedia language seems to be "English", but it seems not to be specified, so it should be "not specified"?

The study made an computer-based experiment to evaluate the performance of their keyphrase extraction method. if "computer-based experiment" is regarded as an "experiment" we should label this as an "experiment."
