WikiSummarizer - A Wikipedia-based Summarization System
Yajie Miao, Chunping Li · 2010
This paper presents our WikiSummarizer system at the guided summarization track of TAC 2010. This system is derived from a novel framework which improves summarization through sentence wikification, i.e., enriching sentence representation with concepts from Wikipedia. By examining sentences in the feature space of Wikipedia concepts, we are able to obtain sentence similarity which is more consistent with human judgment. Furthermore, we develop a strategy which incorporates semantic relatedness of Wikipedia concepts into sentence wikification as a smoothing factor. Our system outperforms the baseline and has achieved competitive results in TAC 2010. 1.
