Discontinuous Dependency Parsing of Free and Fixed Word Order: Work in Progress
نویسنده
چکیده
The dependency–based free–word–order parsing algorithm of Covington (1987, 1990, 1992) can be extended to handle partly or completely fixed word order, while preserving its psychologically realistic preference for near attachment. By adding predictivity, this algorithm can be adapted to parse left–branching and right–branching structures in less stack space than center–embedded structures, just as the human parser appears to do.

Data-driven systems can be adapted to different languages and domains easily. Using this trend in dependency parsing was lead to introduce data-driven approaches. Existence of appreciate corpora that contain sentences and theirs associated dependency trees are the only pre-requirement in data-driven approaches. Despite obtaining high accurate results for dependency parsing task in English langu...
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 کاملExperiments with Easy-first nonprojective constituent parsing
Less-configurational languages such as German often show not just morphological variation but also free word order and nonprojectivity. German is not exceptional in this regard, as other morphologically-rich languages such as Czech, Tamil or Greek, offer similar challenges that make context-free constituent parsing less attractive. Advocates of dependency parsing have long pointed out that the ...
متن کاملDiachronic Trends in Word Order Freedom and Dependency Length in Dependency-Annotated Corpora of Latin and Ancient Greek
One easily observable aspect of language variation is the order of words. In human and machine natural language processing, it is often claimed that parsing freeorder languages is more difficult than parsing fixed-order languages. In this study on Latin and Ancient Greek, two wellknown and well-documented free-order languages, we propose syntactic correlates of word order freedom. We apply our ...
متن کاملDependency-based Analysis for Tagalog Sentences
Interest in dependency parsing increased because of its efficiency to represent languages with flexible word order. Many research have applied dependency-based syntactic analysis to different languages and results vary depending on the nature of the language. Languages with more flexible word order structure tend to have lower performances compared to more fixed word order languages. This work ...
