چکیده

This paper deals with the concept of the “size” or “extent” of the information in the sense of measuring the improvement of our knowledge after obtaining a message. Standard approaches are based on the probabilistic parameters of the considered information source. Here we deal with situations when the unknown probabilities are subjectively or vaguely estimated. For the considered fuzzy quantities valued probabilities we introduce and discuss information theoretical concepts.

One of the major challenges in automated interpetation of spatial natural language is how to model the regions implied by spatial expressions.

Spatio-temporal localization of Vague Geo-environmental Information: Application to volcanological Data

In the field of Environment, it is frequent to find, in data sets describing spatial natural events, some localizations expressed through vague textual expressions (Wang., 2011 ; Jones et al., 2008), such as « nearby », « in the sector of», « towards », « north of », etc. It is the same with temporal localizations, when it comes to expressing the moment when events occur (Nagypal & Motik., 2003...

TIJAH Scratches INEX 2005: Vague Element Selection, Image Search, Overlap, and Relevance Feedback

Retrieving information from heterogeneous data sources in a flexible manner and within a single (database) framework is still a challenge. In this paper we present several extensions of our prototype database system TIJAH developed for structured retrieval. The extensions are aimed at modeling vague selection of XML elements and image retrieval. All three levels (conceptual, logical, and physic...
