Explorations in Sentence Fusion
Erwin Marsi, Emiel Krahmer · Research portal (Tilburg University) · 2005
Sentence fusion is a text-to-text (revision-like) generation task which takes related sentences as input and merges these into a single output sentence.In this paper we describe our ongoing work on developing a sentence fusion module for Dutch.We propose a generalized version of alignment which not only indicates which words and phrases should be aligned but also labels these in terms of a small set of primitive semantic relations, indicating how words and phrases from the two input sentences relate to each other.It is shown that human labelers can perform this task with a high agreement (Fscore of .95).We then describe and evaluate our adaptation of an existing automatic alignment algorithm, and use the resulting alignments, plus the semantic labels, in a generalized fusion and generation algorithm.A small-scale evaluation study reveals that most of the resulting sentences are adequate to good.
