A Two-Phase Stock Trading System Using Distributional Differencese intervals of distinctive distribution may contribute to the prediction of future trend of stocks, so the rules for filtering stocks are induced using those intervals. We show the rates of returns by the proposed trading system, with the usefulness of the rule induction method using distributional

Issues in Monitoring Web Datastructured XMLformat augmented with mechanisms for providing semantics such as RDF. Also, we believe that the very passive vision of web sites promoted by the current HTTP will soon turn into a much more active one based on pub/sub and web services. Thus, the monitoring of the web is likely to raise

Controlled Caching of Dynamic WWW Pagesrver load dramatically, since each request results to code execution, which may involve processing and/or access to information repositories. In this paper we present a scheme for maintaining a server-side cache of dynamically generated pages, allowing for cache consistency maintenance, without plac

Deriving and Verifying Statistical Distribution of a Hyperlink-Based Web Page Quality Metricer needs. We focus on the problem of ascertaining the statistical distribution of some well-known hyperlink basedWebpage quality metrics. Based on empirical distributions ofWebpage degrees, we derived analytically the probability distribution for the Pagerank metric. We found out that it follows the

Ensuring Recovery for SACReD Web Transactions in the E-commerce Applicationsdes reliable recovery from failure in e-commerce applications. This protocol manages complex Web transactions upon multiple distributed Web services, and overcome limitations of two-phase commit protocols by applying correctness criteria based upon semantic atomicity. Further, it supports enhanced t

Transactional Workflows or Workflow Transactions?tness and clear semantics has generally been observed and has lead to the combination of workflow and transaction concepts. Many variations on this combination exist, leading to many approaches to transactional workflow support. No clear classification of these approaches has been developed, however
