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).

Page Titles and Meta Tags
Page titles To help obtain high page rankings with search engines, the contents of your page title are one of the most important things that need to be dealt with. The page title is the first amount of information provided to a search engine describing the contents of the page. You should also be aware that the page title provides information about the contents not only to search engines, but to visitors as well. The page title will show up at the top of the browser window. Your page title should include your keywords and should be no longer than 60 characters long. If it is too long, your visitor will only see the first part. An easy way to figure out the length of a page title is to type it into a word processor that contains a word count feature. Since your page title needs to be a certain length, it is important to make the best use of the space, and although some words that are not key, will use up that valuable space, the title itself still needs to make sense. A keyword in your title can be repeated, but having the same words more than two times is not recommended. Compare your page title to others and see what makes their content look appealing enough to catch a potential visitor's eyes. Your page title needs to stand out between the other nine titles on the search engine results page. As you design your site, remember the fact that visitors may be directed to somewhere other than the homepage because the search engine believes it is the best match for a keyword. With this in mind, all pages of your website should be considered unique and have their own title. Meta tags For your site to be effective, you need to develop Meta tags. These tags are a site description and a keyword list. It is important to note that not all search engines use these Meta tags. Starting with your home page, you will need to insert two Meta tags. The first is a Meta description sentence and the second is a Meta keyword list. The information you put here is for search engines to use when they review your site. This review process is known as crawling and is done with a program called a spider or robot. The description tag serves two purposes. The spiders search it for keywords and it is also displayed to a surfer as they view search engine results. The information obtained by the spiders is kept in a database that is used when a person types in a query to a search engine. When you create your Meta keyword list, order them from the most relevant to the least. The first part of your list should contain the keywords that best describe your site and are unique enough that when someone does a search, there is not a large amount of competition to go up against. Make sure that all the keywords used in the description tags are again listed. The words at the end of your list are known as wildcards and include synonyms and words that could have been spelled wrong when someone was doing a search. During your Meta tag creation process, do not be afraid to go to other people's websites and see what they have used. Type in the same words you would like to include in your lists and see what the search engines display. This is a very good way to help determine your competition.
Creating Your Small Business Website - The Simple Truth
Your Small Business Website doesn't have to be a challenge. You'll be able to get it up and running without a professional web-designer, you'll be able to describe you're unique value proposition, and you'll have an offer waiting to bring in business that already believes your solution is the correct one for them. One of the biggest myths about creating a website is that you have to use a web-designer. Designers can bring a great service, but your goal is to make information available and to interest clients in your products and services. To leverage this, you should look for a templated site. Simply put, that means you pick out a predesigned website and make a few customizations that are appropriate for your business. Usually you have hundreds of choices from which to choose. Then you add your images, upload your logo; and more importantly use your voice to communicate. Quick and dirty in the world of websites can be worth more than you ever thought. Give them a reason to pick your business over the competition. Price isn't the only comparison people are looking for. And sometimes you don't want to compete on price-it limits your audience. Do some research on your clients. How do they search for your product or service? Are you saving people time and stress? Could your value be in the way you integrate with something they are already doing? Formulate your 'sweet spot' in the industry and broadcast it. This is the one piece of information that you can't afford to not include on your website. Make it the central message and use your features and benefits to back it up. State your offer! You've got their attention now make them an offer. So often a company puts so much energy and effort into their website, but they forget to ask for the sale. Whether you are selling products or services, you must give them explicit instructions about their next step. Should they sign up for a newsletter? Download a report? Call for an appointment? Customers love simple directions for the next step. Present your features and benefits and then drive them into a sale. Otherwise you're leaving money on the table. So you've made the offer. They identify with the features and benefits, but how do they know that this is really for them? You need to offer proof. This could be a video on youtube demonstrating the actual benefit or perhaps testimonials from your customers. This is big because you've led them down the path of searching and research. Make sure they know that they have chosen correctly. You ease their mind and add third-party credibility to your site's visitors by including statements from like-minded customers. Many times small business owners are fearful of their website. They don't know what it requires to set up a website or what it needs to include. Taking action can be as simple as finding an easily editable templated site that you can quickly customize, broadcasting your unique value statement, asking for the sale, and providing credibility from others. Erase the fear and profit from your small business website.
