Simplification of Patent Claim Sentences for Their Paraphrasing and Summarization

We present an approach to patent claim simplification which segments claim sentences into clausal discourse units, transforms them into complete sentences, establishes coreference relations and builds a discourse structure between discourse units. The four stages are necessary to allow for the syntactic analysis of otherwise unparsable claim sentences and their regeneration using discourse structure and coreference relations in order to ensure the production of a cohesive and coherent paraphrase/summary. Motivation In order to facilitate the comprehension of patent claims, which are very hard to read due to their complex linguistic style, we developed a rule-based paraphrasing and summarization module (Wanner et al. in press) that consists of three main components: the claim simplification component, the parsing component, and the regeneration component. In what follows, we focus on the claim simplification component. Claim simplification segments claim sentences into clausal discourse units, transforms them into complete sentences, establishes coreference relations and, finally, builds a discourse structure between discourse units. The four stages are necessary to allow for the syntactic analysis of otherwise unparsable claim sentences and their regeneration using discourse structure and coreference relations in order to ensure the production of a cohesive and coherent paraphrase/summary.
