Recommended Gateway Sites for the Deep Web Recommended Gateway Sites for the Deep Web And Specialized and Limited-Area Search Engines This portion of the Internet consists of information that requires interaction to display such as dynamically-created pages, real-time information and databases. Currently estimated to be over 100 times larger than the surface web, the Deep Web houses billions of documents in databases and other sources, over 95% of which are available to the public. As crawler-based search engines cannot access these documents, specialized sources such as these currently provide our only access.

The Ultimate Guide to the Invisible Web Search engines are, in a sense, the heartbeat of the internet; “Googling” has become a part of everyday speech and is even recognized by Merriam-Webster as a grammatically correct verb. It’s a common misconception, however, that Googling a search term will reveal every site out there that addresses your search. Typical search engines like Google, Yahoo, or Bing actually access only a tiny fraction — estimated at 0.03% — of the internet. The sites that traditional searches yield are part of what’s known as the Surface Web, which is comprised of indexed pages that a search engine’s web crawlers are programmed to retrieve. "As much as 90 percent of the internet is only accessible through deb web websites." So where’s the rest? So what is the Deep Web, exactly? Search Engines and the Surface Web Understanding how surface pages are indexed by search engines can help you understand what the Deep Web is all about.

What do we mean by “Semantic” Web? - Buzz’s Blog: On Web 3.0 and the Semantic Web Feb 27 2009 3:26AM GMT Posted by: Roger King Tags: Thanks! We'll email youwhen relevant content isadded and updated. Following Follow namespaces the Semantic Web Web 2.0 Web 3.0 Web development This is the third in a continuing series of blogs about the Semantic Web and Web 2.0/3.0. Let’s look carefully at that word. Even though it is very far from completely existing, the Semantic Web effort is a number of years old now. So, what do we mean when we use this word, in particular, with regard to the Semantic Web? Like a human or “natural” language, a programming language has two key aspects: syntax and semantics. Interestingly, a human statement can be syntactically correct, while its semantics might be ambiguous. There is a broader – and far more ill-defined – use of the word “semantics” in computing. Very important: when we look at the structure of the data, it includes all the terms used to describe the data. Yes, in fact. What about the rest of the definition of data on the Semantic Web? Wow.
Database search engine There are several categories of search engine software: Web search or full-text search (example: Lucene), database or structured data search (example: Dieselpoint), and mixed or enterprise search (example: Google Search Appliance). The largest web search engines such as Google and Yahoo! utilize tens or hundreds of thousands of computers to process billions of web pages and return results for thousands of searches per second. High volume of queries and text processing requires the software to run in highly distributed environment with high degree of redundancy. Modern search engines have the following main components: Searching for text-based content in databases or other structured data formats (XML, CSV, etc.) presents some special challenges and opportunities which a number of specialized search engines resolve. Database search engines were initially (and still usually are) included with major database software products. See also External links
