An Ontology-Supported Web Focused-Crawler for Java Programs

Abstract
This paper proposed an ontology-support web
focused-crawler: OntoCrawler III for Java programs,
in which only the user entered some keywords would
the system supported by the domain ontology actively
provide comparison and verification for those
keywords so as to up-rise the precision and recall
rates of webpage searching. This technique has
practically been installed in Google and Yahoo search
engines and furthermore searched and filt ....etc

Search Engine with Web Crawler

A web crawler (also known as a Web spider or Web robot) is a program or automated script which browses the World Wide Web in a methodical, automated manner.

This process is called Web crawling or spidering. Search engines use spidering as a means of providing up-to-date data. Web crawlers Download and will index web pages to provide fast searches.

A Web crawler starts with a list of URLs to visit, called the seeds. As the crawler visits these URLs, it identifies all the hyperlinks in the page and adds the ....etc

ABSTRACT

Context-dependent behavior is becoming increasingly important for a wide range of application domains, from pervasive computing to common business applications. Unfortunately, mainstream programming languages do not provide mechanisms that enable software entities to adapt their behavior dynamically to the current execution context. This leads developers to adopt convoluted designs to achieve the necessary runtime exibility. We propose a new programming technique called Context-oriented Programming (COP) which addresses this ....etc

Recent surveys have shown the WWW is still remaining undiscovered by Search Engines and through Human Intervention. This is primarily due to the lack of Infrastructure and cost factor of such hardware which required to carrying out such processes. My endeavour in finding a solution to this will be focusing on Idle Computer time available in Compute clusters. Deployed client applications will harvest the web and return the results to the Server Computer. Compute Clusters may create through Voluntary Computing or by using specific Infrastructure ....etc

It is a common experience while web searching that one gets to see pages that are not of interest. Partly these are due to a word or words in the search query having different contexts, the user obviously expecting to find pages related to the context of interest. This paper proposes a method for disambiguating contexts in web search results.

Geographically Distributed Web Crawler

Introduction
Web crawling is a resource intensive process, both in terms of processing and in terms of communication. Distributing the crawling activity among multiple machines can distribute processing, and spreading out the distribution geographically can significantly reduce the communication cost. The reduction in communication is because of the following reasons. ¢By choosing a crawler nearer to a web server being crawled, the http fetch of the content on the web server ....etc
