Sentence simplification is important in making written materials, including health information, more accessible to readers with low literacy. Performing this simplification automatically, via a computer program, is desirable, especially given the amount of information available on the web. One aspect of sentence simplification involves dividing sentences containing relative clauses into two sentences. A relative clause is connected by a relative pronoun, such as “which,” to the main sentence. When the relative clause becomes a separate sentence, the program needs to replace “which” with the correct subject for the new sentence. Sometimes this is straight-forward. Other times, it is not. One troublesome area is “…noun preposition noun which…” In this situation it can be difficult to choose which noun should replace “which.” While this is a fairly well understood problem, in this paper we re-examine the problem and report our findings and suggest some novel approaches.
