We propose a supervised lexical substitution system that does not use separate classifiers per word and is therefore applicable to any word in the vocabulary. Instead of learning word-specific substitution patterns, a global model for lexical substitution is trained on delexicalized (i.e., non lexical) features, which allows to exploit the power of supervised methods while being able to general...

Phonological sensitivity to lexical class has been addressed in the literature; at least two sets of hypotheses have been advanced regarding its codification in grammar. The first type of approach holds that lexical class differences are limited by restrictions in the design of grammar itself (or more specifically, Universal Grammar): for example, it has been hypothesized that only faithfulness...

Natural language processing (NLP)--the automatic analysis, understanding and generation of human language by computers--is vitally dependent on accurate knowledge about words. Because words change their behaviour between text types, domains and sub-languages, a fully accurate static lexical resource (e.g. a dictionary, word classification) is unattainable. Researchers are now developing techniq...

In this paper we present a family of kernel functions, named Syntagmatic Kernels, which can be used to model syntagmatic relations. Syntagmatic relations hold among words that are typically collocated in a sequential order, and thus they can be acquired by analyzing word sequences. In particular, Syntagmatic Kernels are defined by applying a Word Sequence Kernel to the local contexts of the wor...

  Abstract Critical Discourse Analysis as an interdisciplinary approach aims at making transparent the connections between discourse practices and social practices and provides ways of looking into translations from a critical standpoint.Farahzad is among the scholars who presented her specific CDA model inspired by Fairclough’s approach. The present Critical Discourse Analysis (CDA)-based s...

Sub-categorized arguments introduced by the French preposition pour has been under-studied in previous work, as can be seen from the incompleteness of existing lexical-syntactic resources in that regard. In this paper, we briefly introduce the various types of sub-categorization in pour, which are to be distinguished from occurrences of pour as a discourse connective. We describe how we added a...

This paper proposes a principled approach for analysis of semantic relations between constituents in compound nouns based on lexical semantic structure. One of the difficulties of compound noun analysis is that the mechanisms governing the decision system of semantic relations and the representation method of semantic relations associated with lexical and contextual meaning are not obvious. The...

This thesis proposal outlines the use of unsupervised data-driven methods for paraphrasing tasks. We motivate the development of knowledge-free methods at the guiding use case of multi-document summarization, which requires a domain-adaptable system for both the detection and generation of sentential paraphrases. First, we define a number of guiding research questions that will be addressed in ...

The separated electromagnetic responses RL(q, ω) and RT (q, ω) for inclusive electron scattering off nuclei are studied within a functional scheme.
