More Than Parsing

چکیده
We introduce Generalised Object Normal Form (GONF), a syntax formalism that enables language designers to de ne concrete syntax in a form that also naturally de nes the data structure of the abstract syntax tree. More precisely, GONF's grammatical productions specify simultaneously and without annotations (1) concrete syntax (a language and its parser) and (2) the collection of languageindependent data type de nitions representing the abstract syntax tree accurately and concisely. These types can be materialised in languages supporting inheritance or algebraic types, and preferably parametric polymorphism. We also describe MTP, an available GONF-based tool.

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 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 کاملFeature extraction in opinion mining through Persian reviews
Opinion mining deals with an analysis of user reviews for extracting their opinions, sentiments and demands in a specific area, which can play an important role in making major decisions in such area. In general, opinion mining extracts user reviews at three levels of document, sentence and feature. Opinion mining at the feature level is taken into consideration more than the other two levels d...

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 Extended Theory of Head-Driven Parsing
We show that more head-driven parsing algorithms can he formulated than those occurring in the existing literature. These algorithms are inspired by a family of left-to-right parsing algorithms from a recent publication. We further introduce a more advanced notion of "head-driven parsing" which allows more detailed specification of the processing order of non-head elements in the right-hand sid...

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...
