Transforming Complex Sentences into a Semantic Hierarchy
Table 1: Linguistic constructs addressed by DisSim.
['[EMPTY]', 'Clausal/Phrasal type', '# rules']
Subtask 1: Sentence Splitting and Rephrasing. The decomposed text spans, as well as the remaining text span are then transformed into new stand-alone sentences. In order to ensure that the resulting simplified output is grammatically sound, some of the extracted text spans are combined with their corresponding referents from the main sentence or appended to a simple phrase (e.g. “This is”). In that way, the simplification rules encode both the splitting points and rephrasing procedure for reconstructing proper sentences. Both coordinate and subordinate clauses, as well as various types of phrasal elements are addressed by our TS approach.
