The project LE-SIMPLE is an innovative attempt of building harmonized syntactic-semantic lexicons for 12 European languages, aimed at use in different Human Language Technology applications. SIMPLE provides a general design model for the encoding of a large amount of semantic information, spanning from ontological typing, to argument structure and(More)
The focus of this paper is on the work we are carrying out to develop a large semantic database within an Italian national project, SI-TAL, aiming at realizing a set of integrated (compatible) resources and tools for the automatic processing of the Italian language. Within SI-TAL, ItalWordNet is the reference lexical resource which will contain information(More)
Optimizing the production, maintenance and extension of lexical resources is one the crucial aspects impacting Natural Language Processing (NLP). A second aspect involves optimizing the process leading to their integration in applications. With this respect, we believe that the production of a consensual specification on lexicons can be a useful aid for the(More)
The importance and role of multi-word expressions (MWE) in the description and processing of natural language has been long recognized. However, multi-word information has often been relegated to the marginal role of idiosyncratic lexical information. The need for MWE lexicons grows even more acute for multilingual applications, for which (sometimes(More)
BACKGROUND Due to the rapidly expanding body of biomedical literature, biologists require increasingly sophisticated and efficient systems to help them to search for relevant information. Such systems should account for the multiple written variants used to represent biomedical concepts, and allow the user to search for specific pieces of knowledge (or(More)
[11] Dan Klein and Christopher D. Manning. Fast exact inference with a factored model for natural language parsing. Another more practical line of activity includes an error analysis to identify the classes of errors done by the two algorithms, so that strategies to cope with them can be designed. For Collins' parsers this would imply the introduction of(More)
CLIPS is a multi-layered Italian computational lexicon based on the PAROLE-SIMPLE model. In this paper we briefly recall the main characteristics of the model and devote our attention to issues emerging from the encoding of large quantities of data, especially in relation to those types of syntactic and semantic information specific to our lexicon and that(More)
