Ontologies represent a method of sharing and reusing knowledge on the semantic web. A fuzzy ontology is an extension of domain ontologies for solving the problems of uncertainty. This paper shows how a Fuzzy Ontology based approach can represent user profiles in e-learning environments. The ontological representation of the user profile enhances the performance in tasks such as filtering and information...
Maximality is a desirable property of paraconsistent logics, motivated by the aspiration to tolerate inconsistencies, but at the same time retain as much as possible from classical logic. In this paper we introduce a new, strong notion of maximal paraconsistency, which is based on possible extensions of the consequence relation of a logic. We investigate this notion in the framework of finite-valued...
Widget aggregators such as iGoogle and Netvibes are broadly adopted by the mass market. They enable end-users to personalize their environment with their preferred services (Widgets). However, the usage in an enterprise context is not yet investigated. In this paper, we firstly show that in addition to personalization capability, the integration of business processes should be considered. Secondly,...
Graph grammar has been employed as a tool to express formal logic of graph structures. Among different mechanisms, pullback categorical grammars have been proved to be intrinsically context-free. We will show in this paper that this kind of graph grammar can be used for modeling a mechanism which generates square grids and only square grids. With semantics this mechanism will be a good candidate for...
We present a consequence relation for graded inference within the frame of infinite-valued Lukasiewicz semantics. We consider the premises to be true to at least a certain degree A and consider as consequences those sentences entailed to have a degree of truth at least some suitable threshold B. We focus on the study of some aspects and features of the consequence relation presented and, in particular,...
Knowledge workers are central to an organization's success, yet their information management tools often hamper their productivity. This has major implications for businesses across the globe because their commercial advantage relies on the optimal exploitation of their own enterprise information, the huge volumes of online information, and the productivity of the required knowledge work. The Active...
If software engineering tools are not "properly integrated", they can reduce engineers' productivity. Associating and retrieving information scattered across the tools become unsystematic and inefficient. Our work provides empirical evidence on what is a "poor" and a "proper" tool integration, focusing on practitioners' perspectives. We interviewed 62 engineers and analyzed...
