In this paper, we propose two different alternatives to deal with degraded queries on Spanish Information Retrieval applications. The first is based on character n-grams, and has no dependence on the linguistic knowledge and resources available. In the second, we propose two spelling correction techniques, one of which has a strong dependence on a stochastic model that must be previously built ...

We present a novel vector space model for semantic co-compositionality. Inspired by Generative Lexicon Theory (Pustejovsky, 1995), our goal is a compositional model where both predicate and argument are allowed to modify each others’ meaning representations while generating the overall semantics. This readily addresses some major challenges with current vector space models, notably the polysemy...

Machine-readable dictionaries (henceforth MRDs) are a valuable source of lexical data for the automatic construction of lexical knowledge bases (LKBs). However, the transfer of information from one source to the other one often demands a filtering process, since in many cases the original dictionaries contain mistakes, redundancies and granularity irregularities. We claim that this filtering pr...

Meaning shifting phenomena such as metonymy have recently attracted increasing interest of researchers. Though these phenomena have been addressed by a variety of computational methods, the impacts of cardinalities of metonymically related items have been widely ignored in all of them. Motivated by this lack of analysis, we have developed a method for representing expectations and knowledge abo...

This paper studies the importance of qualia relations for Word Sense Disambiguation (WSD). We use a graph-based WSD algorithm over the Italian WordNet and evaluate it when adding different kinds of qualia relations (agentive, constitutive, formal and telic) taken from PAROLE-SIMPLE-CLIPS (PSC), a Language Resource based on the Generative Lexicon theory. Some qualia relations, specially telic, a...

The compositional operation of a predicate can be very complex. This paper captures a full picture of such an operation through investigating genuine corpus data of Chinese perception verb “看” (kàn, look at). The study reveals that context and qualia structure can affect the meaning of verb-argument composition of “kàn”. It also shows that the compositional ability of “kàn” varies under differe...

In this paper, we propose an approach to distributional semantics which can be formally related to a simple model-theoretic approach. We describe treatments of some of the traditional lexical semantic relationships within this framework, and also outline accounts of some phenomena which have been considered within Generative Lexicon theory. We further argue that distributions should be based on...

This paper attempts to argue that the so-called gapless relative clause (GRC) in Korean (Chinese and Japanese as well) can best be dealt with by the Generative Lexicon Theory (GLT) put forward in Pustejovsky (1995). There arises a superficial conflict in the construction: the GRC, with no apparent gap, contains a relative verb that does not directly relate to the head noun in terms of causeeffe...

In the field of Computational Linguistics, many lexical resources have been developed which aim at encoding complex lexical semantic information according to different linguistic models (WordNet, Frame Semantics, Generative Lexicon, etc.). However, these resources are often not easily accessible nor available in their entirety. Yet, from the point of view of the continuous growth of technology ...
