I envision another big leap forward by automatically harvesting and organizing knowledge from the Web, represented in terms of explicit entities and relations as well as ontological concepts. This will be made possible by the confluence

Hence, this paper show how these protocols could be modelled and made accessible to partners involved in an IOW. More precisely, the paper proposes a coordination protocol ontology for IOW and explains how workflow partners can

Most traditional data mining methods only deal with a single table and discretize columns that contain continuous numbers into nominal values. In a relational database, multiple records with nume

If the size of data set is large, the sequential or binary search of NNs is inapplicable due to the increased computational costs. Therefore, indexing schemes are frequently use

As a result, these methods are ineffective on (a) very large datasets stored in databases or data warehouses, (b) data whose partitioning into classes cannot be captured by global models and is sensitive to local characteristics, and (c) data that arrives c

However, this is infeasible in many cases, e.g., if the system is to be generated ad hoc from a conceptual schema..This paper presents an iterative process that helps domain experts to create a conceptual schema without the need for a modelli
