Design of an Enhanced Rule Based Focused Crawler
2008 First International Conference on Emerging Trends in Engineering and Technology, 2008The rapid growth of World Wide Web has urged the development of retrieval tools like search engines. Topical crawlers have gained large momentum in recent years. In this paper, a parallel web spider model, based on multi-agent system for cooperative information gathering is presented. The system collects Web pages that are on topic.

CRAWLER-LD: A Multilevel Metadata Focused Crawler Framework for Linked Data
2015The Linked Data best practices recommend to publish a new tripleset using well-known ontologies and to interlink the new tripleset with other triplesets. However, both are difficult tasks. This paper describes CRAWLER-LD, a metadata crawler that helps selecting ontologies and triplesets to be used, respectively, in the publication and the interlinking ...

A Novel Focused Crawler Based on Breadcrumb Navigation
2012In this paper, a novel focused crawler based on Breadcrumb Navigation (BN) is proposed. It mainly leverages Breadcrumb Navigation in the webpages to reconstruct the website structures and resolve focused crawling problems. Different from some previous focused crawlers which use prediction models, the BN crawler firstly samples the web to construct the ...

Developing of an Ontological Focused-Crawler for Ubiquitous Services
22nd International Conference on Advanced Information Networking and Applications - Workshops (aina workshops 2008), 2008This paper proposes the use of several ontological techniques to provide a semantic level solution for a search agent so that it can provide fast, precise, and stable search results in ubiquitous information environments. An ontological focused-crawler had been developed according to these techniques, which can benefit both user requests and domain ...
