Designed and developed a Web Prediction Tool (WebPT) in JDK1.2 environment.
WebPT is a tool that predicts the expected delay for Web query based on learning
query feedback from WebSources.
Integrated WebPT, WebSource (HTML/XML) Extractor and Wrapper Statistics
into Wrapper Cost Model (WCM) via a Java RMI server. Extended current wrapper
mediator architectures to build Web Query Processor and Web Query Optimizer for
heterogeneous WebSource data.
