Contextual reasoning distilled

Contextualized knowledge repositories for the Semantic Web

“…The knowledge base is structured into units called contexts with contextual attributes explicitly assigned; this allows to group axioms and data that are assumed to hold under similar circumstances, and improves topical organization and maintenance of the knowledge base. Such approach is also well in line with the context as a box paradigm which opens the possibility to exploit the existing body of research on contextual representation [9,10] in applications of the framework.…”

“…Building on the foundations of contextual knowledge representation [8,16,10,11] we have proposed Contextualized Knowledge Repository (CKR) -a context-aware representation framework specifically tailored for the Semantic Web. CKR offers several distinctive features.…”

“…In his seminal paper [8] McCarthy suggested to formalize context in terms of first-class objects and utilize it in reasoning. Further research lead to introduction of the context as a box metaphor [9,10] for suitable representations of contexts. In this approach, each context is a set of formulae which hold under the same circumstances and whose boundaries are Email addresses: serafin@fbk.eu (Luciano Serafini), homola@fmph.uniba.sk (Martin Homola) delimited by a set of dimensional attributes.…”

Peer-Mediated Distributed Knowledge Management

“…Knowledge representation in artificial intelligence and cognitive science have produced many theoretical and experimental evidences of the fact that what people know is not a mere collection of facts; indeed, knowledge always presupposes some (typically implicit) interpretation schema, which provide an essential component in sense-making (see, for example, the notions of context (McCarthy 1993;Benerecetti, Bouquet, & Ghidini 2000;Ghidini & Giunchiglia 2001) space (Fauconnier 1985), partitioned representation (Dinsmore 1991)); studies on the social nature of knowledge stress the social nature of interpretation schemas, viewed as the outcome of a special kind of "agreement" within a community of knowing (see, for example, the notions of scientific paradigm (Kuhn 1979), frame (Goffaman 1974)), thought world (Dougherty 1992), perspective (Boland & R.V.Tenkasi 1995)). …”

Word Sieve: A Method for Real-Time Context Extraction

“…By observing the user's interaction with the computer to determine contextual cues, these agents can suggest information that is likely to be useful in the current context. Much research has studied the formalization of context (e.g., [2,5,4])), and rich context representations have been proposed (e.g., [18,19]). However, the circumstances in which information retrieval agents function strongly constrain the context extraction methods and representations that are practical for them to use.…”
