Restricted quanti cation poses a serious and under-appreciated challenge for non-classical approaches to both vagueness and the semantic paradoxes. It is tempting to explain All A are B as For all x, if x is A then x is B ; but in the non-classical logics typically used in dealing with vagueness and the semantic paradoxes (even those where 'if ... then' is a special conditional not de nable in ...

This paper is directed towards an infrastructure for handling both uncertainty and vagueness in the Rules, Logic, and Proof layers of the Semantic Web. More concretely, we present probabilistic fuzzy description logic programs, which combine fuzzy description logics, fuzzy logic programs (with stratified nonmonotonic negation), and probabilistic uncertainty in a uniform framework for the Semant...

This research presents a methodology for the ontological formalisation of vague spatial concepts from natural language, with an application to the automatic recognition of event occurrences on video data. The main issue faced when defining concepts sourced from language is vagueness, related to the presence of ambiguities and borderline cases even in simple concepts such as ‘near’, ‘fast’, ‘big...

I experimentally investigate how vague language changes the nature of communication in a biased strategic information transmission game. Counterintuitively, when both precise and imprecise messages can be sent, aggregate, senders are more accurate, receivers trust them than only sent. also develop structurally estimate model showing that increase between boundedly rational players, especially i...

2 Overview The purpose of this project is the application of the bibliometric Bradford Law of Scattering (BLS) for generating core document sets for subject specific questions. BLS is used to reorder result sets and discover interdisciplinary properties of result sets from distributed searches. Introduction The background of the research project is that distributed search across multiple databa...

Event detection and tracking is a somewhat recent area of information retrieval research. The detection is about spotting new, previously unreported real-life events from online news-feed, while the tracking assigns documents to previously spotted events. We propose a new vector model consisting of four semantic classes from the documents: locations, proper names, temporal expressions and norma...

In this paper is analyzed the prototyping of a faceted semantic search for personalized social search using the “joint meaning” as procedure to deal with vagueness on ontological indeterminacy in a community environment representing an evolution of the actual social networks like Facebook, Myspace, Linkedin, Twitter, VirgilioPeople, ... The intent of this work is to discuss how the most common ...
