A Computer Science Text Corpus/Search Engine X-Tec and Its Applications

摘要

We built a computer science text corpus/search engine called X-Tec. We automatically collected 2.98 million sentences (68.9 million words) from carefully chosen English computer science documents on the Web using 678 hours. We also built an interactive sample sentence query system and an automatic expression diagnostic system for graduate students. Our computer science text corpus/search engine can be also used for knowledge search and word co-occurrence frequency retrieval.
