| Outline of Final Research Achievements |
Aiming at an improvement of syntactic dependency analysis of English sentences, we compiled an English multi-word expression (MWE) lexicon and an MWE-annotated corpus. We also developed an algorithm for coordination structure analysis on top of dependency structure analysis.
For English MWEs, we collected English functional multi-word expressions and performed MWE annotation on Penn Treebank. We also implemented an MWE-aware English dependency parsing algorithm. We collected English complex sentence patterns and made annotation on made annotation on complex sentence examples.
For coordinate structure analysis, we proposed a joint algorithm of dependency and coordinate structure analysis and implemented a prototype system.
