Feature Engineering in Persian Dependency Parser
Dependency parser is one of the most important fundamental tools in the natural language processing, which extracts structure of sentences and determines the relations between words based on the dependency grammar. The dependency parser is proper for free order languages, such as Persian. In this paper, data-driven dependency parser has been developed with the help of phrase-structure parser fo...
متن کاملOn Different Approaches to Syntactic Analysis Into Bi-Lexical Dependencies An Empirical Comparison of Direct, PCFG-Based, and HPSG-Based Parsers
We compare three different approaches to parsing into syntactic, bi-lexical dependencies for English: a ‘direct’ data-driven dependency parser, a statistical phrase structure parser, and a hybrid, ‘deep’ grammar-driven parser. The analyses from the latter two are post-converted to bilexical dependencies. Through this ‘reduction’ of all three approaches to syntactic dependency parsers, we determ...
متن کاملPhrase structure and dependence
Syntactic structures have been analysed in terms of constituent hierarchies and also in terms of dependency relations. While these two traditions have sometimes been presented as competing with each other, there is no reason in principle why syntactic dependencies and constituent hierarchies should not both be part of the grammar, complementing each other. Indeed, within transformational gramma...
متن کاملFinding Non-local Dependencies: Beyond Pattern Matching
We describe an algorithm for recovering non-local dependencies in syntactic dependency structures. The patternmatching approach proposed by Johnson (2002) for a similar task for phrase structure trees is extended with machine learning techniques. The algorithm is essentially a classifier that predicts a nonlocal dependency given a connected fragment of a dependency structure and a set of struct...
متن کاملDutch Cross Serial Dependencies in HPSG
We present an analysis of Dutch cross serial dependencies in Head-driven Phrase Structure Grammar ((P&S(1994)]). We start out from the assumption that causative and perceptual verbs, like auxiliaries, can lexically`raise' the arguments of the non-nite verbs they govern to their own list of arguments through \argument composition" ((H&N(1989)]).
