Effective Website Development
Internet is the new media that has been creating a buzz everywhere lately. Be it an aspiring musician or model or a successful organization, everyone now wants to make their presence felt on the new media, the much hyped and talked about internet. And this online presence is often done by creating a website or webpage containing useful information along with media files that help to highlight the USP of the individual or organization. The main idea is to get an edge over competition by venturing into a newly and still largely untapped region. But this "untapped region" is not so untapped after all. It's a common trend for businesses and individuals to go online in the present day and this has again effectively introduced a new area of competition. There are millions of websites and webpages scattered all over the World Wide Web and the numbers are growing every single second. So how does a particular site stand out from its competitors, attract more clients and exert the maximum influence? In order to answer this question, we need to understand the source of visitors to any website. There can be many sources like hyperlinks from a particular page, word of mouth and viral procedures. However, the primary source of visitor to any website is through the search engines. Search engines list websites on the basis of a number of parameters and the ones listed on the first page, especially towards the top, gets more visitors than the others. In order to get a website listed on the top of any search engine result index, a whole lot of technical issues need to be taken care of. These are known as search engine optimization techniques. However, it's not just these techniques that would help a website to gain advantage over its competitions. The SEO techniques require support from the design aspects too. For example a particular website with very good search engine listing would attract a lot of visitors but if it does not have a proper navigation facility, the visitors would not be able to find what they are looking for and would eventually abandon the site. It is definitely not possible by any one person to handle all the aspects of an effective website. So the best possible option is to go for professional help. One good thing is, presently there are several companies that offer professional website development service at an affordable rate. However, it's best to have an overview of the services they offer before entrusting one with the job. A firm that offers a whole bunch of services right from the development of the site, the designing aspects and search engine optimization techniques to support each other would surely be the best choice. Thus it could be concluded that website development services are quite essential in order to have an effective website developed, for individuals or organizations interested in making their presence felt on the internet and gain advantage over competitions.
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 Navigation
Importance of a navigation scheme One of the most important tasks when developing your website is creating a navigation system that is effective and easy to use. People have a tendency to try to include everything in the navigation tree all at once. Instead they should follow the same process as setting up the structure for the site and break it down in levels. This would be information relevant to the homepage that directs visitors to the main sections of the site. From the main sections of the site, the user gains access to the sub sections containing content pertinent to that section only. Remember to always include links back to the main sections and your homepage on every page in your site. While you are creating your navigation setup, try to look through your user's eyes. Remember, you are the one creating the structure, so you are biased in your opinions. If you think about what someone else might say or do, then you are one step ahead of the game. As you create you website navigation, make sure that links can be added in the future with no difficulty. You must always keep in mind that your site must be flexible and open to change because it is never completed. All links should be clear and to the point. It makes no sense to have your visitor try to figure out where they are going. They should be able to quickly look for what they want and then access it in a timely and efficient method. There is a better chance of a visitor going somewhere else if it takes too long for them to find the information they are looking for. Your navigation scheme should stick out and be located in a common spot on every page of your site. Consistency allows your visitors to focus on the content instead of trying to figure another navigation system for the same site. Linear navigation Linear navigation provides the same capabilities as your forward and back button on your browser. With this navigation style, you cannot jump around and skip pages. Reading a book or viewing a PowerPoint presentations are also examples of linear navigation. As you read through the pages, it makes no sense to jump around or you might miss an important piece of information. People who create sites with this style often are directing the visitor from a starting point to a predetermined end in a step by step fashion. Your links will not allow the user to anywhere other than where you want. Hierarchical navigation Hierarchical navigation allows the visitor to go from a homepage to the main sections of your site and then to the subsections. Visitors can travel through your site without any restrictions. This type of navigation ties all the areas of your site together so any page can be accessed from another in as few clicks as possible. Hierarchical navigation is best used on sites that are filled with information and to be utilized like a library. Sitemaps for navigating through your website Sitemaps provide a list of organized links to the content of your website. The same way a table of contents tells you what is inside a book, a sitemap does the same for your website. Your visitors are given a one page view of the information structure that your site is based on. Sitemaps are not meant to be your websites primary navigation but more as a compliment to it. Navigation bars A navigation bar gives your visitors the ability to move between the different sections of your website. It should be placed on every page of your site and should be consistent as well. Placement of the navigation bar is entirely up to you. The navigation bar can go on the left side of your page because most people read from left to right. It can also be placed on the top of your page so it is the first thing your visitors see. Some people place it on the right hand side of the page intentionally making a visitor browse through content to then be able to navigate the rest of the site. Theme and navigation links The theme for a website is created with the way you use color, fonts and images. During the theme creation process, remember to not clutter your pages with unnecessary content that will draw your visitor's attention from the main content. There are many ways to create a theme. One example might be a newspaper look consisting of black and white colors with a plain font. Themes give a website character and often leave a strong visual impression on the visitor. Your website theme needs to be used on all your pages which helps tie your site together. Navigation Navigation of a website should be an easy process and not require the visitor to take much time in figuring out how to move through your site. Visitors have come to your site looking for information and should be able to find it easily. If a visitor has to waste time figuring out how to get what they want, they will go to another site. Navigation is not just for people, but search engines as well. Set up the navigation to allow search engines to follow the links to index your entire website. Your navigation scheme should appear in the same place on all pages. When a visitor navigates through your site, make sure they can flow through it. Do not set it up so a visitor has to use the back button of the browser to access another page. Through navigation, your visitor will have access to pages in your site, to other sites and to different sections of the pages on your site. You will need to place navigation menus in more than one area on your pages. There are many good ways to help the visitor move through your site. The most simple is a text link. The next is a navigation bar placed on the top or sides. Another is the use of graphic buttons created to help compliment the overall look of your site. It is always good idea is to include links at the bottom of your page in case someone does not feel like scrolling back to the top. Through navigation, your visitor should be able to get where they want quickly, know where they currently are on your site and be able to access other pages on your site for additional information.
