Chinese Proposition Bank 2.0 is a continuation of the Chinese Propostion Bank project, which aims to create a corpus of Chinese text annotated with information about basic semantic propositions. Chinese Propostion Bank 1.0 consists of predicate-argument annotation on 250,000 words from Chinese Treebank 5.0. Chinese Proposition Bank 2.0 adds predicate-argument annotation on 500,000 words from Chinese Treebank 6.0. The data sources include newswire from Xinhua News Agency, articles from Sinorama Magazine, news from the website of the Hong Kong Special Administrative Region and transcripts from various Chinese broadcast news programs.
This release contains the predicate-argument annotation of 81,009 verb instances (11,171 unique verbs) and 14,525 noun instances (1,421 unique nouns). The annotation of nouns is limited to nominalizations that have a corresponding verb. The general annotation guidelines and the lexical guidelines (called frame files) for each verbal and nominal predicate are included in this release.
