Proceedings of READIT-2009, Kalpakkam - 603 102, 29-30 Dec 2009 “Directories,” which maintain ordered lists of websites provide e.g. Yahoo similar services! www.liv.ac.uk/webteam/glossary/ A tool or program, which allows keyword searching for relevant sites or information on the Internet. General and topic-specific search engines are prevalent today, for example, Education World, WebCrawler, Info seek, Lycos, and Yahoo are examples of search engines. www.education-world.com/help/glossary.shtml HOW DOES SEARCH ENGINES WORK? Search engine databases are selected and built by computer robot programs called spiders. Although it is said they "Crawl" the web in their hunt for pages to include, in truth they stay in one place. They find the pages for potential inclusion by following the links in the pages they already have in their database (i.e., already "know about"). They cannot think or type a URL or use judgment to "decide" to go look something up and see what's on the web about it. (Computers are getting more sophisticated all the time, but they are still brainless.) After spiders find pages, they pass them on to another computer program for "indexing." This program identifies the text, links, and other content in the page and stores it in the search engine database's files so that the database can be searched by keyword and whatever more advanced approaches are offered, and the page will be found if your search matches its content. SEMANTIC WEB SEARCH ENGINES: Unlike traditional search engines, which crawl the Web gathering Web pages, Semantic Web search engines index RDF data stored on the Web and provide an interface to search through the crawled data. Below is a list of Semantic Web search engines that are currently under development. Semantic Search engines are: 1. SEMANTIC WEB SEARCH ENGINE (SWSE): is a search engine for the RDF Web on the Web, and provides the equivalent services a search engine currently provides for the HTML Web. The system explores and indexes the Semantic Web and provides an easy-to-use interface through which users can find the information they are looking for. Because of the inherent semantics of RDF and other Semantic Web languages, the search and information retrieval capabilities of SWSE are potentially much more powerful than those of current search engines. 109 2
Proceedings of READIT-2009, Kalpakkam - 603 102, 29-30 Dec 2009 2. SINDICE: is a lookup index for Semantic Web documents built on data intensive cluster computing techniques. Sindice indexes the Semantic Web and can tell which sources mention a resource URI, IFP, or keyword, but it does not answer triple queries. Sindice currently indexes over 20 million RDF documents. 3. WATSON : Allows you to search through ontologies and semantic documents using keywords. At the moment, you can enter a set of keywords (e.g. "cat dog old_lady"), and obtain a list of URIs of semantic documents in which the keywords appear as identifiers or in literals of classes, properties, and individuals. You can also use wildcards in the keywords (e.g., "ca? dog*"). Developed by KMi, UK. 4. YAHOO! MICROSEARCH : Microsearch is Yahoo!'s stab at Semantic Web search and provides a richer search experience by combining traditional search results with metadata extracted from Web pages. Indexes RDF, RDFa and Microformats crawled from the Web. Microsearch will soon be adding support for GRDDL. 5. FALCONS : Falcons is a keyword-based search engine for the Semantic Web, equipped with browsing capability. Falcons provides keyword-based search for URIs identifying objects and concepts (classes and properties) on the Semantic Web. Falcons also provides a summarization for each entity (object, class, property) for rapid understanding. Falcons currently indexes 7 million RDF documents and allows you to search through 34,566,728 objects. Developed by IWS China. 6. SEMANTIC WEB SEARCH : Powered by RDF Gateway, Intellidimension's proprietary platform for Semantic Web applications and agents. Developed by Intellidimension Inc. 7. ZITGIST SEARCH : The Zitgist Query Service simplifies the Semantic Data Web Query construction process with an end-user friendly interface. The user need not conceive of all relevant characteristics - appropriate options are presented based on the current shape of the query. Search results are displayed through an interface that enables further discovery of additional related data, information, and knowledge. Users describe characteristics of their search target, instead of relying entirely on content keywords. 1. SWOOGLE : Searches through over 10,000 ontologies. 2.3 million RDF documents indexed, currently including those written in RDF/XML, N-Triples, N3(RDF) and some documents that embed RDF/XML fragments. Currently, it allows you to search through ontologies, instance data, and terms (i.e., URIs that have been defined as classes and 110 3
