Abstract

Sentence compression is a method of text summarisation, where each sentence in a text is shortened in such a way as to retain the original information and grammatical correctness as much as possible. In a previous paper, we formulated the problem of sentence compression as an optimisation problem of extracting a subsequence of phrases from the original sentence that maximises the sum of topical importance and grammatical correctness. Based on this formulation an efficient sentence compression algorithm was derived. This paper reports a result of subjective evaluation for the quality of sentences compressed by using the algorithm.
