Furthermore, following the proposed approach, we implement an automated learning tool, which can automatically construct fuzzy ontologies from FOOD models. Case studies show that

Uncertain conditions bring to infer more than one situation with different certainty degrees: these degrees are used to assign a rank to concu

Source Selection in Large Scale Data Contexts: An Optimization Approachel to distinguish the sets of sources that maximize benefits and minimize the number of sources to contact to while satisfying resource constraints. The precision and recall of source selection is highly improved as demonstrated by the tests performed with the OptiSource prototype.

Efficient Incremental Near Duplicate Detection Based on Locality Sensitive Hashing the existing point set which are found when they are inserted into the data set, and use them to prune LSH candidate sets for the newly arrived point. Extensive experiments based on three real-world data sets show that our method consistently outperforms the original LSH approach: to reach the same

Efficient Fuzzy Top-, Query Processing over Uncertain Objectsning method is proposed to safely prune some objects before querying. The effectiveness and efficiency of our algorithms is demonstrated by the theoretical analysis and experiments with synthetic and real datasets.

A Disk-Based, Adaptive Approach to Memory-Limited Computation of Windowed Stream Joinse allocated memory within the stream windows. The problem of managing the window blocks in memory—similar in nature to the caching issue—captures both the temporal and frequency related properties of the stream arrivals. The algorithm adapts memory allocation both at a window level and a partition l
