Generating queries from user-selected text

Abstract

People browsing the web or reading a document may see text passages that describe a topic of interest, and want to know more about it by searching. Manually formulating a query from that text can be difficult, however, and an effective search is not guaranteed. In this paper, to address this scenario, we propose a learning-based approach which generates effective queries from the content of an arbitrary user-selected text passage. Specifically, the approach extracts and selects representative chunks (noun phrases or named entities) from the content (a text passage) using a rich set of features. We carry out experiments showing that the selected chunks can be effectively used to generate queries both in a TREC environment, where weights and query structure can be directly incorporated, and with a "black-box" web search engine, where query structure is more limited.
