The proposed semantic information retrieval system handles the following : i) automatic spell correction of user query. ii) analysis and determination of the semantic feature of the content and development of a semantic pattern that represents the semantic features of the content. iii) analysis of user’s query and extension of implied semantics through semantic extension to identify more semant...

Accurately capturing the quantifier scope behaviour of coordinated NPs can be problematic for some underspecified semantic representations. We present an extension to hole semantics that allows a natural representation of sentences containing NP coordination, and which correctly captures the quantifiers’ scoping behaviour. We demonstrate that existing efficient algorithms developed to solve con...

In this work we describe Semantic Turkey, a Semantic Extension for the popular web browser Mozilla Firefox. Semantic Turkey can be used to keep track of relevant information from visited web sites and organize collected content according to a personally defined ontology. In this sense, Semantic Turkey can be seen both as an advanced semantic bookmarking system as well as an ontology editing ass...

In this work we introduce Semantic Turkey, a Semantic Extension for the popular web browser Mozilla Firefox. Semantic Turkey can be used to keep track of relevant information from visited web sites and organize collected content according to a personally defined ontology. Clear separation between knowledge data (the WHAT) and web links (the WHERE) is established into the knowledge model of the ...

This paper presents a novel approach for semantic query extension using a probabilistic description logic. Concepts that are related to a keyword-based query are used for finding other concepts and relations through the use of a relational Bayesian network built using the probabilistic description logic crALC. Furthermore, probabilistic assessments allow us to rank the information returned by s...

To achieve semantic interoperability, geo-spatial applications need to be equipped with tools able to understand user terminology that is typically different from the one enforced by standards. In this paper we summarize our experience in providing a semantic extension to the geo-catalogue of the Autonomous Province of Trento (PAT) in Italy. The semantic extension is based on the adoption of th...
