Action verbs have many meanings, covering actions in different ontological types. Moreover, each language categorizes action in its own way. One verb can refer to many different actions and one action can be identified by more than one verb. The range of variations within and across languages is largely unknown, causing trouble for natural language(More)
In this paper we look at how Generative Lexicon theory can assist in providing a more thorough definition of word senses as links between items in a RDF-based lexicon and concepts in an ontology. We focus on the definition of lexical sense in lemon and show its limitations before defining a new model based on lemon and which we term lemonGL. This new model(More)
This paper describes the publication and linking of (parts of) PAROLE SIMPLE CLIPS (PSC), a large scale Italian lexicon, to the Semantic Web and the Linked Data cloud using the lemon model. The main challenge of the conversion is discussed, namely the reconciliation between the PSC semantic structure which contains richly encoded semantic information,(More)
Purple urine bag syndrome (PUBS) is a unique disease entity characterized by an alarming purple discoloration of the urine secondary to recurrent urinary tract infections with indigo- and indirubin-producing bacteria. It is usually associated with prolonged urinary catheterization and chronic debilitated states. We hereby present a concise review of this(More)
In this article we will outline two different vocabularies, both extensions of the lemon model, for representing diachronic lexico-semantic data on the Semantic Web. This is especially useful for representing the evolution of scientific terminologies where many terms are polysemous and or imported from other languages. The first vocabulary, polyLemon,(More)
Knowledge about semantic associations between words is effective to disambiguate word senses. The aim of this paper is to investigate the role and the relevance of telic information from SIMPLE in the disambiguation of basic action types of Italian HOLD verbs (prendere, 'to take', raccogliere, 'to pick up', pigliare 'to grab' etc.). We propose an experiment(More)
In this work we propose a model for the representation of the narrative of a literary text. The model is structured in an ontology and a lexicon constituting a knowledge base that can be queried by a system. This narrative ontology, as well as describing the actors, locations, situations found in the text, provides an explicit formal representation of the(More)
