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).

Tips To Help You Build A Money Making Website
Any of us who are interested in making money online are bombarded daily with information relative to achieving this objective. Along with this it seems that everyday there is a new technique and if you do not apply it you could be leaving thousands of dollars on the table. Many of these opportunities involve creating your own website. This way you can earn revenue using multiple techniques. And of course on the business opportunity sales pages they often say that this can be done within weeks of implementing their strategies. While in some cases this may be true it is often more the exception rather than the rule. I do not want to burst anyone's bubble. I have been marketing online for almost four years and honestly it takes grit and determination to build a successful business on the internet. The truth is it can be done but many factors have to be brought into consideration before you begin. The first being how many hours per day are you willing to spend to build your online business. By the way do not be fooled into thinking that an online business does not have to be taken as seriously as an offline business. If you do not take it seriously then you will not achieve serious results. The step to take is to outline on a piece of paper what your interests are. Then you will need to research the market online to see which way you can enter the market and make money. In terms of building a website you need to gather all this information first. Once you find what you are looking for and have determined that you are going to build a site relative to that subject you can then look for a site builder that will help you achieve the results you desire to achieve. The best site builders are the ones that have proven results. Secondly if you are not technically minded you want it to take care of all those details. Remember if you are busy building a site then you will not be marketing your website hence you will not be making money. To conclude apply due diligence. Research your market thoroughly and you will achieve results.
You Can Build Your Own Great Web Site
Last February, I received a call from a man in Wisconsin asking about my writing services. He was particularly interested in having me rewrite the copy on his Web site. I was very surprised and wondering how in the heck he got my name. Then he mentioned something about my being my Internet hosting service's "customer of the month." I was very pleasantly surprised. After I spoke with him, I logged onto my email and there was an e-newsletter from my host server. And, yes, I was the "customer of the month," and my Web site was the featured site for the month. Of course, I quickly hastened to my site and checked the traffic. I was up to over 300 visits to my home page for the morning, and the day was to end with 796 visits! I don't believe I'll ever see numbers like that again. I also received several other calls from people interested in my services. It wasn't a complete surprise that my site was featured. Last year, I had filled out a "success story" response form on the company's site. I was later interviewed and told that I would be used as a case study. But the case study never materialized so I had forgotten about it. Thus I was very pleased when my site landed in their e-newsletter as the featured site. My host is one of many companies where you can register domain names and get your business online. They will build a site for you; or, if you are cheap like me, you can build your own. When I began my business a few years ago, I waited a whole year for my brother who owns an ad agency in L.A. to professionally build my Web site for free. Now he's kind of successful, and he didn't get that way by doing a lot of free work for relatives. At the time, my server was doing a lot of radio advertising claiming you could "build your Web site in 20 minutes." One day after nagging my brother once more, he became exasperated and said, "Why don't you just build your own." So I did. I called the company and they provided templates and lots of help. I chose an animated template with a layout ideal for showcasing a portfolio. There was a bit of a learning curve. I had to play around and call for help a few times. It took me longer than 20 minutes; yet, technically, the commercial was accurate: you could really get a home page up with your contact info in 20 minutes. I believe I spent about 20 hours to get my Web site to the point where I was willing to "publish" it. One of the advantages I have found about building your own Web site is that you don't have to rely on an outside Web Master to update it. Sometimes those fellows are swamped and it can take awhile. If I want to put a new project in my online portfolio, I can do it in a few minutes. Or if I want to add something new to my list of services, I can quickly type it in and it's done. I found a huge difference in how I was perceived in the business community once I had a Web presence. Suddenly, I was taken seriously. These days when someone asks, "What's your Web address?" you should have it ready. And it should never be "under construction." Visitors find that very irritating. It's really not that hard to get a presentable Web site up. As I mentioned earlier, there are numerous places where you can go to build a Web site. Just Google "do it yourself Web site" and you will get numerous options. It is very inexpensive. My site costs me less than $100 a year for 20 pages. Some places are even cheaper. Compared to the thousands of dollars one can pay a Web designer, it's a sweet deal. That's not to say that I don't believe in professionally designed Web sites. I still want one with more bells and whistles. I'm just waiting on my brother. (Since initially writing this piece, my server has made the process even better. It's more professional, a lot more pages available ... and more bells and whistles.)
