Context-driven query extraction for content-basedrecommender systems faces the challenge of dealing with queriesof multiple topics. In contrast to manually entered queries, forautomatically generated queries this is a more frequent problem. For instances if the information need is inferred indirectly viathe user's current context. Especially for federated search systemswere connected knowledge sources...
Of all the perspectives about what inconsistencies entail and how we can handle them, one that escapes our attention is that inconsistencies can serve as effective stimuli to learning because they often help reveal the inadequacies, gaps, deficiencies, or boundary conditions in an agent's problem-solving knowledge. In this paper, we describe a new machine learning approach: inconsistency-induced learning...
We present a logic for Proximity-based Understanding of Conditionals (PUC-Logic) that unifies the Counterfactual and Deontic logics proposed by David Lewis. We also propose a natural deduction system (PUC-ND) associated to this new logic. This inference system is sound, complete, normalizing and decidable.
Stream processing is about processing continuous streams of data by programs in a workflow. Continuous execution is discretized by grouping input stream tuples into batches and using one batch ata time for the execution of programs. As source input batches arrive continuously, several batches may beprocessed in the workflow simultaneously. Ensuring correctness of these concurrent executions isimportant...
In this paper, we improve a computational conceptof logic-based consensus among agents that has been introducedrecently. A consensus is defined as a non-contradictoryfragment of the information conveyed by various agents suchthat this fragment does not logically conflict with any agent. In this study, we introduce an additional requirement to theconcept of consensus to avoid some paradoxical consensuses...
The paper explores the connection between Soren Hallden's logic of nonsense (and its expansions) and Logics of Formal Inconsistency (LFIs), one of the main traditions in paraconsistency. Although not much attention has been payed by paraconsistentists, Hallden's logic can be nicely connected to LFIs. The main result of the paper is a reformulation of an expansion of logic of nonsense studied by Lennart...
