Query Expansion using LMF-Compliant Lexical Resources
نویسندگان
چکیده
This paper reports prototype multilingual query expansion system relying on LMF compliant lexical resources. The system is one of the deliverables of a three-year project aiming at establishing an international standard for language resources which is applicable to Asian languages. Our important contributions to ISO 24613, standard Lexical Markup Framework (LMF) include its robustness to deal with Asian languages, and its applicability to cross-lingual query tasks, as illustrated by the prototype introduced in this paper.

COLDIC, a Lexicographic Platform for LMF compliant lexica
Despite of the importance of lexical resources for a number of NLP applications (Machine Translation, Information Extraction, Event Detection and Tracking, Question Answering, among others), there has been a traditional lack of generic tools for the creation, maintenance and management of computational lexica. The most direct obstacle for the development of such generic tools, that is, independ...
متن کاملProlexbase and LMF: towards a standard for Proper Name lexical resources
We present in this paper how Prolexbase can be expressed within the LMF (Language resource management Lexical Markup Framework) ISO project framework. Prolexbase is a lexical resource of proper names, organized according to an onomasiological view, with entries based on the concept of conceptual proper name. In the same time, Prolexbase also focuses on morphological description of proper names....
متن کاملStandardizing lexical-semantic resources - Fleshing out the abstract standard LMF
This paper describes the application of the Lexical Markup Framework (LMF) for standardizing lexical-semantic resources in the context of NLP. More specifically, we highlight the question how lexical-semantic resources can be made semantically interoperable by means of LMF and ISOCat. The LMF model UBY-LMF, an instantiation of LMF specifically for NLP, serves as an example to illustrate the pat...
متن کاملA Re-examination of Query Expansion Using Lexical Resources
Query expansion is an effective technique to improve the performance of information retrieval systems. Although hand-crafted lexical resources, such as WordNet, could provide more reliable related terms, previous studies showed that query expansion using only WordNet leads to very limited performance improvement. One of the main challenges is how to assign appropriate weights to expanded terms....
متن کاملA prototype for projecting HPSG syntactic lexica towards LMF
The comparative evaluation of Arabic HPSG grammar lexica requires a deep study of their linguistic coverage. The complexity of this task results mainly from the heterogeneity of the descriptive components within those lexica (underlying linguistic resources and different data categories, for example). It is therefore essential to define more homogeneous representations, which in turn will enabl...
