Integrating Multiple Knowledge Sources for Robust Semantic Parsing
Jordi Atserias, Lluis Padro, German Rigau
This work explores a new robust approach for Semantic Parsing of unrestricted texts. Our approach considers Semantic Parsing as a Consistent Labelling Problem (CLP), allowing the i…
A Complete WordNet1.5 to WordNet1.6 Mapping
J. Daudé, L. Padró, G. Rigau
We describe a robust approach for linking already existing lexical/semantic hierarchies. We use a constraint satisfaction algorithm (relaxation labelling) to select --among a set o…
Mapping WordNets Using Structural Information
J. Daude, L. Padro, G. Rigau
We present a robust approach for linking already existing lexical/semantic hierarchies. We used a constraint satisfaction algorithm (relaxation labeling) to select --among a set of…
Mapping Multilingual Hierarchies Using Relaxation Labeling
J. Daude, L. Padro, G. Rigau
This paper explores the automatic construction of a multilingual Lexical Knowledge Base from pre-existing lexical resources. We present a new and robust approach for linking alread…
On the Evaluation and Comparison of Taggers: The Effect of Noise in Testing Corpora
L. Padro, L. Marquez
This paper addresses the issue of {\sc pos} tagger evaluation. Such evaluation is usually performed by comparing the tagger output with a reference test corpus, which is assumed to…
A Hybrid Environment for Syntax-Semantic Tagging
Lluis Padro
The thesis describes the application of the relaxation labelling algorithm to NLP disambiguation. Language is modelled through context constraint inspired on Constraint Grammars. T…
