We present an approach to estimating concept drift in online news. Our method is to construct temporal concept vectors from topicannotated news articles, and to correlate the distance between the temporal concept vectors with edits to the Wikipedia entries of the concepts. We find improvements in the correlation when we split the news articles based on the amount of articles mentioning a concep...

One of the important barrier that hinders achieving semantic interoperability is ontology matching. Instancebased ontology matching (IBOM) uses the extension of concepts, the instances directly associated with a concept, to determine whether a pair of concepts is related or not. In practice, however, instances are often associated with concepts of a single ontology only, rendering IBOM rarely a...

In this paper, we describe ways of enhancing concept mapping tools to facilitate representation and use of superimposed information. Superimposed information refers to new interpretation of existing information and involves working with information at various document granularities (sub-document, complete document, and multi-document). We illustrate our approach by showing how enhanced concept ...

AHP (Analytic Hierarchy Process) has been widely used in decision making. Inner dependence method AHP is one technique even in case of criteria have dependency. However using original AHP or Inner dependence method, the results often lose reliability because the comparison matrix does not always have sufficient consistency. In these cases, fuzzy representation for weighting criteria and alterna...

The centrality of the self-concept in maintaining physical and psychosocial well-being is widely recognized in nursing. Despite its importance, progress in the development of an empirically-supported and clinically-relevant theoretical framework has been limited by difficulties in defining and measuring the construct. The schema model of the self-concept is presented as a theoretical framework ...

This paper describes several means for sharing between related concepts to improve learning in the same domain. The sharing comes in the form of substructures or possibly entire structures of previous concepts which may aid in learning other concepts. These substructures highlight useful information in the domain. Using two domains, we evaluate the e ectiveness of concept sharing with respect t...

Given a Brouwerian complete lattice (L,≤) and two referential sets K and E, and using a fuzzy relation R ∈ L which is reflexive and symmetric, certain fuzzy relations Ĥ ∈ L are characterized as solutions of X C R = X. These solutions Ĥ can be determinated by means of the L-fuzzy concepts associated with the K-labeled L-fuzzy context (L,K,E,E,R).
