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 ...

Habanera is a multipurpose multilingual lexical knowledge base that is developed at CRL to be used as a central repository of multilingual lexical data. The knowledge base contains a set of dictionaries and relations between entries, within a dictionary (e.g., synonymy) as well as between entries of different dictionaries (e.g., translation). The format of monolingual lexical entries is left re...

In this paper, we describe a method of extracting information from an on-line resource for the consmaction of lexical entries for a multi-lingual, interlingual MT system (ULTRA). We have been able to automatically generate lexical entries for interlingual concepts corresponding to nouns, verbs, adjectives and adverbs. Although several features of these entries continue to be supplied manually w...

This paper describes the SyntaLex entries in the English Lexical Sample Task of SENSEVAL-3. There are four entries in all, where each of the different entries corresponds to use of word bigrams or Part of Speech tags as features. The systems rely on bagged decision trees, and focus on using pairs of lexical and syntactic features individually and in combination. They are descendants of the Dulu...

The following paper presents an approach for simulating the acquisition of new lexical entries for unknown words, an issue that is central to natural language processing since no lexicon can ever be complete. Acquisition involves two main tasks. First, the appropriate information about an unknown word in a given linguistic context (i.e. sentence) is identified. It is shown that this task requir...

In this paper we describe the overall model for MILE lexical entries and provide an instantiation of the model in RDF/OWL. This work has been done with an eye toward the goal of creating a web-based registry of lexical data categories and enabling the description of lexical information by establishing relations among them, and/or using predefined objects that may reside at various locations on ...

We describe how unknown lexical entries are processed in a unification-based framework with large-coverage grammars and how from their usage lexical entries are extracted. To keep the time and space usage during parsing within bounds, information from external sources like Part of Speech (PoS) taggers and morphological analysers is taken into account when information is constructed for unknown ...

We present an approach to lexical ambiguity where regularities about sense/u~ge extensibillty are represented by underepecifying word entries through lexic~d polymorphism. Word diumbiguation is carried out using contextual information gathered during language processing to ground polymorphic lexical entries.

This paper proposes a new computational treatment of lexical rules as used in the HPSG framework. A compiler is described which translates a set of lexical rules and their interaction into a definite clause encoding, which is called by the base lexical entries in the lexicon. This way, the disjunctive possibilities arising from lexical rule application are encoded as systematic covariation in t...
