Semantic Web
Introduction Semantic web as defined by the creator of the web Tim Berners-Lee is "a web of data, in some ways like a global database" (Berners-Lee, 1998). To elaborate further Mr. Berners-Lee explains in an interview held by IDG Now, data is expressed on computers as associated files with applications that deal specifically with information, an example would be, data in calendars, bank systems, spreadsheets, and database application. Looking at a web page, data is not clearly defined and not associated with any of the applications usually on computers. Semantic web will allow data to interact and connect together; it will bring on a common data format for all applications, for databases and web pages alike (Moon, 1999). Semantic web is not to build an artificial intelligence system which allows computers to understand what humans write on web pages; on the contrary, it is an attempt to make web pages more understandable and well-defined to support automatic extraction of data from within web content (Berners-Lee, 1998). Analysis The emergence of the web and the way HTML took off was driven by how society's needed to grew, from Internet chat to file transfer to high-end communities through blogs and wiki's. HTML was not limited to web content, knowledge base and help files adapted the language as a format to document software applications and provide training material. The revolution of technologies on the Internet allowed companies like Google to index pages; a thought that was very far away, says Tim Berners-Lee in his lecture at MIT. Web services have evolved to pave the road for distributed information and modular programming allowing interoperability among sites. Through XML, data in one site can be used by another using the common protocols and standards supported by both (Berners-Lee, 1998). XML defines schemas that deal with fields of data, what is required is a system that can tell the computer what sort of information (data) it can derive from within a page (Moon, 1999). With Web 3.0 a site will provide data that can be navigated through and extracted from multiple sites, this is a result of the fact that semantic web data model is closely related to a relational database where records of data share common fields that connect them together (Berners-Lee, 1998). The solution provided to support semantic web is in the form of metadata that describes the data contained on web pages. Resource Description Framework (RDF) is a base to manage metadata; it is the ground that computers can use to exchange and interact with applications on the Web (W3C RFC, 1999). The applications for RDF include digital libraries, online catalogs, and indexing systems that are usually associated with content and content relationships models deployed in most web pages. With RDF data within business portals will be analyzed and identified as resources, properties, or statements transparent to the domain, further more, the specifications will merge with other documents to comprise a framework of classes. Classes organized as a hierarchy comprises a schema that can be reusable as metadata definitions along side multiple platforms. Resources created in this hierarchy can be identified using a resource identifier (URI), which enables a document given to a machine with this identification to be recognized by the system and triggers it to dig and find similar data (Berners-Lee, 1998). Implications Semantic web can be the solution to overpower the limitations of current information management systems in finding and extracting data from unorganized resources. RDF is meant to describe any data regardless of its character, location, source, or type, the concept of URI is richer to uniquely identify any object on the web (Berners-Lee, 1998). The pillars of Semantic web are standards and common protocols that are the bases for knowledge representation; HTML, RDF, the data language resource description web ontology language (OWL) that describes to the machine what is going on, in addition to RDF1 which is a query language to make inquiries among machines much easer, will all emerge and collaborate to bring in more to the web and more intelligent programs that will bring the Internet more closer (Cleave, 2004). The current research and implementation of Abilene network and the Next Generation Internet (NGI) Internet 2 of high-performance backbone network linking major universities and research labs across the US, is a good foundation for what Semantic web can do, and represent the perfect platform for grid computing, digital libraries, virtual laboratories, and distance learning (Abilene, Internet2). Internet2 or I2 was developed by a group of universities in 1996 providing improved connectivity standards to reach 10gbps (gigabits per second). With more than 227 universities and libraries connected, network based applications and experimental programs can run on this network of high-bandwidth connection feeding on the latest technology of gigabit Ethernet and IP protocol version 6 (Reardon, 2004). Semantic web standards can be the base of material and data distributed on this network, providing the best test platform to explore the full potential and what can be achieved. Conclusion Tim Berners-Lee believes that with Web 3.0 we can succeed and fantastic things can happen, but the infrastructure need to be built, laws of privacy and security need to be revised and honored, further more, the web need to remain open for researchers to allow for continuous upgrade and development. Semantic web will kick off when individuals materialize the need to work on data processing, and think about collaborating their data, with company's information and that of the government (Moon, 1999).

Website Content - 5 Smart Ways To Create Content For Your Website
One should agree that content is the main thing that keeps visitors coming back for more to your website. Without content, your website is a dead duck in the water. Here are 5 smart ways you can create content for your website without breaking an arm and a leg: 1. Outsource Your Content You can hire a professional freelancer to create content for you.

Use RSS Feeds By installing RSS feeds on your site, you can have fresh new content generated practically on the fly. RSS Feeds can typically grab content from new blog posts around the web, news sites and other websites. You can also promote your content via RSS feeds using FeedBurner. 3. Use Blogs Create a blog and allow people to comment on your posts. The comments are also a way of creating content for your site, only you are not writing the content, your readers are. 4. Create A Forum A forum is one of the best ways to have tons of content created for you by others. If you have a popular forum, you'll have loads of fresh new information posted by the forum members. 5. Leverage Articles Take reprint rights articles from article directories and publish them on your own website. There's a whole world of articles out there on article directories that you can use as long as you include the resource box with them.
How To Create A Powerful Website
So you're considering building a website and you may be feeling a little overwhelmed by it all. While this can easily happen it is wise to whip out some note paper and write down exactly what you want to achieve and what steps you need to take in order to get there. So the first thing you are going to need to do is put the foundation in place. This will require extensive research. Now contrary to popular opinion I start this process a little bit differently than what is generally advised. Now while we all know that you need to find a hungry market doing this can be a little more difficult than explained in actual fact that is just like everything else when it comes to doing anything online. Actuality can be quite different from theory. So what I do is visit the article directories. I punch in a keyword that I am interested in and see what articles come up relative to that. Then I check the articles out to see how many page views they have received over a given period of time. If an article receives a lot of page views then I know that there are a number of people looking for information relative to this subject. I also know that if I write an article on this topic that it will receive a lot of page views and as a result get a lot of click throughs to my site which will help me get traffic quickly without having to worry about what Google and everyone else does. Next I visit the forums to see what solutions are being discussed then I go back to the articles and check what the writers are promoting and see if it is a valid good product to help people achieve the goals they desire. If so then I make note of it. Now I feel a little more confident about building a site around this theme. The next thing you have to consider is the domain. A keyword in the domain is helpful but not essential. Your next quest is hosting. You need a good host as this is your life line. Finally you want to be able to build the site effectively so as to achieve good search engine rankings. Keyword research relative to your overall theme will help you to do this plus you need to structure the pages properly so that you site can be understood by the search engines. Do not worry if you lack technical knowledge as there are site builders out there to help you overcome this challenge. Select any of the following links to watch some free videos.
