Syntactic Relations

Exploiting Syntactic Relations

Recently there has been a resurgent interest in syntax-based approaches to information access, as a means of overcoming the limitations of keyword-based approaches. So far attempts to use syntax have been ad hoc, choosing to use some syntactic information but still ignoring most of the tree structure. This thesis describes the design and implementation of SMARTQA, a proof-of-concept question an...

Learning to Disambiguate Syntactic Relations

Natural Language is highly ambiguous, on every level. This article describes a fast broadcoverage state-of-the-art parser that uses a carefully hand-written grammar and probabilitybased machine learning approaches on the syntactic level. It is shown in detail which statistical learning models based on Maximum-Likelihood Estimation (MLE) can support a highly developed linguistic grammar in the d...

Semantic Similarity from Syntactic Relations

This work presents the results of the application of a technique for automatic extraction of semantic relations between words from a corpus. The technique used is the one proposed by Grefenstette in [8]. We proposed contributions for the syntactic context notion adopted in [8], aiming to improve the identification of semantically related words. Such contributions include new information into th...

Induction of Syntactic Collocation Patterns from Generic Syntactic Relations

Syntactic configurations used in collocation extraction are highly divergent from one system to another, this questioning the validity of results and making comparative evaluation difficult. We describe a corpus-driven approach for inferring an exhaustive set of configurations from actual data by finding, with a parser, all the productive syntactic associations, then by appealing to human exper...
