摘要: With syntactically annotated corpora becoming increasingly available for a variety of languages and grammatical frameworks, tree query tools have proven invaluable to linguists computer scientists both data exploration corpus-based research. We provide combined engine (Tregex) manipulation (Tsurgeon) that can operate on arbitrary structures with no need preprocessing. Tregex remedies several expressive implementational limitations existing tools, while Tsurgeon is our knowledge the most utility available.
