| Summary: | 碩士 === 國立清華大學 === 資訊系統與應用研究所 === 103 === We introduce a new method for extracting representative sentential patterns from a corpus for the purpose of assisting ESL learners in academic writing. In our approach, sentences are transformed into patterns for statistical analysis and filtering, and then are annotated with relevant rhetoric moves. The method involves annotating every sentence in a given corpus with part of speech and base phrase information, converting the sentence into formulaic patterns, and filtering salient patterns for key content words (verbs and nouns). We display the patterns in the interactive writing environment, WriteAhead, to prompt the user as they type away.
