Li et al. Incorporating Document Keyphrases in Search Results Incorporating Document Keyphrases in Search Results ABSTRACT

Effectiveness and efficiency of searching and returned results presentation is the key to a search engine. Before downloading and examining the document text, users usually first judge the relevance of a return hit to the query by looking at document metadata presented in the return result. However, the metadata coming with the return hit is usually not rich enough for users to predict the content of the document. Keyphrases provide a concise summary of a document’s content, offering subject metadata characterizing and summarizing document. In this paper, we propose a mechanism of enriching the metadata of the return results by incorporating automatically extracted document keyphrases in each return hit. By looking at the keyphrases in each return hit, the user can predict the content of the document more easily, quickly, and accurately. The experimental results show that our solution may save users time up to 32 % and users would like to use our proposed search interface with document keyphrases as part of the metadata of a return hit
