Based on a linguistically grounded transformation stage, complex sentences are transformed into shorter utterances with a simple canonical structure that can be easily analyzed by downstream applications. To avoid breaking down the input into a disjointed sequence of statements that is difficult to interpret, the author incorporates the semantic context between the split propositions in the form of hierarchical structures and semantic relationships, thus generating a novel representation of complex assertions that puts a semantic layer on top of the simplified sentences. In a second step, she leverages the semantic hierarchy of minimal propositions to improve the performance of Open IE frameworks. She shows that such systems benefit in two dimensions. First, the canonical structure of the simplified sentences facilitatesthe extraction of relational tuples, leading to an improved precision and recall of the extracted relations. Second, the semantic hierarchy can be leveraged to enrich the output of existing Open IE app | | 出版日期 | Book 2022 | | 關(guān)鍵詞 | Open IE; Automatic Text Simplification; Semantic Representation; Natural Language Processing; Syntactic | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-658-38697-9 | | isbn_softcover | 978-3-658-38696-2 | | isbn_ebook | 978-3-658-38697-9 | | copyright | The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Fachmedien Wies |
