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).

Getting your website done up for your online marketing business? What are your expectations for a good website? What are the important factors that you are emphasizing on to get the desired results from your website? How do you plan to achieve such desired results that will project your website favorably with visitors and customers alike? Designing a good website and making it work for you and your online business requires tremendous effort in meticulous planning, serious consideration and purposeful fine-tuning. Without all these factors, the vast amount of time, money and effort spent on starting up the website can all be wasted easily. To achieve website success, it is imperative to consider the following points: (1) Planning Draft the plan for your website. What is the exact purpose for the website? This is important because it will set the direction that should be taken for the whole process of designing your website. (2) Content consideration Content is the meat and forms an integral part of the website. It is important to think about what content should be included on the website. Another aspect will be how often the content should be updated and how to get reoccurring content. (3) Designing the website This plays an important role in keeping your visitors for the first four seconds. The design of your website must speak its intention and desirability very clearly. What it has to show to the visitors must be made known in that very short time span. No beating around the bush whatsoever. It must be distinctly clear in sending its message across. (4) Encouraging visitor participation The website for whatever reason it is being designed must attempt to bring in visitors not only for the sake of traffic but also getting them involved by participating in the signing up of the free articles and newsletters that you are offering. The whole process must one of interaction, not just a one-way communication. (5) Setting up the website This poses no problems simply because there are professional web designers that you can approach for a certain fee, or alternatively, there are nowadays user-friendly software that you can purchase to design and build your own website, bearing in mind that the design has to be somewhat agreeable within limits to the intention of the website. (6) Execution of follow-up It will be extremely damaging if some visitor poses you a question but it is not being followed up within the same day. This reflects poorly on the efficiency on your part. It tarnishes the image of your online customer service. (7) Promoting your website In any marketing campaign, there is the element of promotion. After having posted your new website, it is crucial to spend some time in promoting it. It is new and therefore it has not garnered recognition or publicity withing this short period of time. It must be given some push through promoting it. There would be teething problems initially, so the website must be given close attention and nurturing, at least in this initial phase of being hosted. (8) Executing maintenance of the website Having set up the website on the internet, it is very important to maintain it. Enliven it with new and fresh content. Make it appealing as each day passes by and visitors returning looking forward to reading new information. Put a warm smile on your website everyday. It will be like what honey is to bees. The path to website success is being subtly laid ahead. The prerogative after the website is being hosted is obviously getting visitors to know and come to your website. Without visitors to your website, the whole purpose of designing and hosting it will be defeated. How do you plan to attract visitors to your website? There are several ways of realizing this plan: (1) Submission of your website to various search engines Submitting your site to various search engines will help in some way. Of course, it would be advisable not to place full reliance on them as they can be inconsistent. If budget permits, bidding for a spot on the search engine would be a more viable alternative simply because an extra bit of control can be exercised. Overture.com is one good choice. (2) Put up various free offers Who would not want to accept free offers if given? This can be best executed by explaining why the visitors in accepting the free offers would understand more about their problems on hand. "Grab free information relating to your backaches. You'll receive more of such information if your just sign in and allow me to mail you these free related information on a weekly basis". (3) Put up ads online It is a good opportunity to put up ads online. Run your paid ads in e-zines. Put your ad buried in another person's e-zine, or you can choose to buy a full page ad. The whole process will induce the source of incoming traffic to your website. (4) Use word-of-mouth This method is viral and is usually effective. Let the world know about your website by inserting your personal signature file on your name cards, brochures, leaflets, just to name a few. Inevitably, as this usually turns viral, it will lead to more website visibility. The internet provides the opportunities for online success. All that is needed to be done is to leverage ourselves with technology. It is equally crucial to understand that website success needs good effort in planning, designing, hosting, promotion and maintenance of the website. Nothing is further from the truth that a well-maintained website is one guaranteed of success in the long run.
