Application of Different Techniques to Dependency Parsing of Basque
نویسندگان
چکیده
We present a set of experiments on dependency parsing of the Basque Dependency Treebank (BDT). The present work has examined several directions that try to explore the rich set of morphosyntactic features in the BDT: i) experimenting the impact of morphological features, ii) application of dependency tree transformations, iii) application of a two-stage parsing scheme (stacking), and iv) combinations of the individual experiments. All the tests were conducted using MaltParser (Nivre et al., 2007a), a freely available and state of the art dependency parser generator.

Application of feature propagation to dependency parsing
This paper presents a set of experiments performed on parsing the Basque Dependency Treebank. We have applied feature propagation to dependency parsing, experimenting the propagation of several morphosyntactic feature values. In the experiments we have used the output of a parser to enrich the input of a second parser. Both parsers have been generated by Maltparser, a freely data-driven depende...
متن کاملExploring Treebank Transformations in Dependency Parsing
This paper presents a set of experiments performed on parsing the Basque Dependency Treebank. We have concentrated on treebank transformations, maintaining the same basic parsing algorithm across the experiments. The experiments can be classified in two groups: 1) feature optimization, which is important mainly due to the fact that Basque is an agglutinative language, with a rich set of morphos...
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...

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 کاملTowards A Dependency Parser For Basque
We present the Dependency Parser, called Maxuxta, for the linguistic processing of Basque, which can serve as a representative of agglutinative languages that are also characterized by the free order of its constituents. The Dependency syntactic model is applied to establish the dependency-based grammatical relations between the components within the clause. Such a deep analysis is used to impr...
