Online Evaluation of Clustered Search Engine Results Design, Implementation and Results

Nowadays, XML is the document model in favour for both documentand data-centric web applications. Its influence in other, more traditional projects and applications grows as the web and associated techniques become the de-facto standard in user interfaces in such systems. We present an XML-sensitive search engine (Xircus) suited for processing semi-structured queries over large collections of X...

This article describes the rationale behind the PHASAR system (Phrase-based Accurate Search And Retrieval), a professional Information Retrieval and Text Mining system under development for the collection of information about metabolites from the biological literature. The system is generic in nature and applicable (given suitable linguistic resources and thesauri) to many other forms of profes...

Searching online has become part of the everyday lives of most people. Whether to look for information about the latest gadget to getting directions to a popular trend, most people have made search engines part of their daily routine. Beyond trivial applications, search engines are increasingly becoming the sole or primary source directing people to essential information. For this reason, searc...

We have to reconsider whether the current structure of search engines provides us with useful results. A modular approach to constructing spiders will facilitate more development, hopefully resulting in new information retrieval techniques. A layered architecture will improve our access to data on the Internet, which is crucial in our information driven society. q 1999 Elsevier Science B.V. All...

In a remote or local environment in which a sensor network always collects data produced by sensors attached to physical objects, the engine presented here saves the data sent through the Internet and searches for data segments that correspond to real-world events by using natural language (NL) words in a query that are input in an web browser. The engine translates each query into a physical q...

Web crawlers have been used for nearly a decade as a search engine component to create and update large collections of documents. Typically the crawler and the rest of the search engine are not closely integrated. If the purpose of a search engine is to have as large a collection as possible to serve the general Web community, a close integration may not be necessary. However, if the search eng...

We present a new approach in web search engines. The web creates new challenges for information retrieval. The vast improvement in information access is not the only advantage resulting from the keyword search. Additionally, much potential exists for analyzing interests and relationships within the structure of the web. The creation of a hyperlink by the author of a web page explicitly represen...
