Using Co-Occurrence Statistics As An Information Source For Partial Parsing Of Chinese
نویسندگان
چکیده
Our partial parser for Chinese uses a learned classifier to guide a bottom-up parsing process. We describe improvements in performance obtained by expanding the information available to the classifier, from POS sequences only, to include measures of word association derived from co-occurrence statistics. We compare performance using different measures of association, and find that Yule’s coefficient of colligation Y gives somewhat better results over other measures.

Automatic identification of words with semantic roles (such as Agent, Patient, Source, etc.) in sentences and attaching correct semantic roles to them, may lead to improvement in many natural language processing tasks including information extraction, question answering, text summarization and machine translation. Semantic role labeling systems usually take advantage of syntactic parsing and th...
متن کاملAn improved joint model: POS tagging and dependency parsing
Dependency parsing is a way of syntactic parsing and a natural language that automatically analyzes the dependency structure of sentences, and the input for each sentence creates a dependency graph. Part-Of-Speech (POS) tagging is a prerequisite for dependency parsing. Generally, dependency parsers do the POS tagging task along with dependency parsing in a pipeline mode. Unfortunately, in pipel...
متن کاملDILUCT: An Open-Source Spanish Dependency Parser Based on Rules, Heuristics, and Selectional Preferences
A method for recognizing syntactic patterns for Spanish is presented. This method is based on dependency parsing using heuristic rules to infer dependency relationships between words, and word co-occurrence statistics (learnt in an unsupervised manner) to resolve ambiguities such as prepositional phrase attachment. If a complete parse cannot be produced, a partial structure is built with some (...

In this paper, the role of Part-of-Speech (POS) tagging for parsing in automatic processing of the Persian language is studied. To this end, the impact of the quality of POS tagging as well as the impact of the quantity of information available in the POS tags on parsing are studied. To reach the goals, three parsing scenarios are proposed and compared. In the first scenario, the parser assigns...
متن کاملMachine Learning of Syntactic Attachment from Morphosyntactic and Semantic Co-occurrence Statistics
The paper presents a novel approach to extracting dependency information in morphologically rich languages using co-occurrence statistics based not only on lexical forms (as in previously described collocation-based methods), but also on morphosyntactic and wordnet-derived semantic properties of words. Statistics generated from a corpus annotated only at the morphosyntactic level are used as fe...
