Enhancing Query-oriented Summarization based on Sentence Wikification

Query-oriented summarization is primarily concerned with synthesizing an informative and well-organized summary from a document collection for a given query. In the existing summarization methods, each individual sentence in the document collection is represented as Bag of Words (BOW). In this paper, we propose a novel framework which improves query-oriented summarization via sentence wikification, i.e., enriching sentence representation with Wikipedia concepts. Furthermore, we exploit semantic relatedness of Wikipedia concepts as a smoothing factor in sentence wikification. The experiments with benchmark dataset show that sentence wikification performs effectively for improving query-oriented summarization, and helps to generate more high-quality summaries.
