It tries to maximize the benefits for all parties. Argumentation-based negotiation has been proposed as an alternative to proposal-based approaches such as game theory and heuristic. The(More)
Encryption algorithms used in privacy preserving protocols can be affected on overall performance. In this paper we study several encryption algorithms with two methods of privacy preserving association rule mining on distributed horizontal database (PPARM4, and PPARM3). The first method PPARM4 computes association rules that hold globally while limiting(More)
Text Categorization is a technique for assigning documents based on their contents to one or more pre-defined categories. Achieving highest categorization accuracy remains one of the major challenges and it is also time consuming. We proposed approach to tackle these challenges. The proposed approach uses Frequency Ratio Accumulation Method (FRAM) as a(More)
