Web Based Information System and NavigationStructure of the Website • Website structure is the process of defining the look and feel and the navigation of CM websites. • A site structure is normally the role of an information architect, the reality is that everybody from designers to website owners find themselves working on it. • The website structure consists of three components: Layout Templates, URL patterns, and Linkage Structure. www.ThesisScientist.comLayout Template • Most web pages consist of HTML elements like table, menu, button, image, and input box. • The layout of a web page describes what HTML elements are included in the page, as well as how these elements are visually distributed in page rendering. • In a website, pages are generated based on distinguishable templates according to their functions. • Visually similar pages usually have same function. In this way, user can easily identify a page’s function at a glance. www.ThesisScientist.comLayout of Site www.ThesisScientist.comURL Pattern • A URL pattern is a generalization of a group of URLs sharing similar syntactic format. • Some example URL patterns discovered, again, from the ASP.NET Forums. – List-of-thread pages • http://forums\.asp\.net/\d+\.aspx • http://forums\.asp\.net/\d+\.aspx\?PageIndex=\d+&forumoptions=\d+:\d+:\d+:: – List-of-post pages • http://forums\.asp\.net/t/\d+\.aspx • http://forums\.asp\.net/t/\d+\.aspx\?PageIndex=\d+ • http://forums\.asp\.net/p/\d+/\d+\.aspx • http://forums\.asp\.net/ThreadNavigation\.aspx\?PostID=\d+&NavType=(PreviousNext) – User profile pages • http://forums\.asp\.net/user/Profile\.aspx\?UserID=\d+ • http://forums\.asp\.net/members//? • It is noticed that one layout templates can have more than one related URL pattern. For example, a bookseller website usually designs one template to show a list of books, and provides different query parameters to generate such a list. • Various query parameters in this scenario will lead to different URL patterns, but the search results are shown with the same template. • Another common case is duplicate pages, i.e., pages with the same content (and very likely the same layout) but different URLs. www.ThesisScientist.comLink Structure • Based on the layout templates and URL patterns, we can construct a directed graph to represent the website organization structure. • Each layout template is considered as a node in a graph, and two nodes are linked if there are hyperlinks between the pages belonging to the two nodes. • The link direction is the same as the related hyperlinks. And each link is characterized with the URL pattern of the corresponding hyperlink URLs. • It should be noticed that there could be multiple links from one node to another if the corresponding hyperlinks have more than one URL pattern. www.ThesisScientist.comWeb Structure • WEB STRUCTURE is a pioneer in "fusion engineering"; fusing design sensitivity with cost consciousness to develop the most cost effective structures in which the traditional separation between architectural design and structures is erased in a seamless harmony of design intent. • In the completed work, architecture and structure resonate to create a single entity; an essential symbiotic interaction, a fusion that presents itself in works of beauty. www.ThesisScientist.comSite Structure • When confronted with a new and complex information system, users build mental model. • They use these models to assess relations among topics and to guess where to find things they haven’t seen before. • The success of the organization of web site will be determined largely by how well site’s information architecture matches users’ expectations. • A logical, consistently named site organization allows users to make successful predictions about where to find things. • Consistent methods of organizing and displaying information permit users to extend their knowledge from familiar pages to unfamiliar ones. • If you mislead users with a structure that is neither logical nor predictable, or constantly uses different or ambiguous terms to describe site features, users will be frustrated by the difficulties of getting around and understanding what you have to offer. • Don’t want user’s mental model of web site to look like figure1. www.ThesisScientist.comFigure 1 — Don’t make a confusing web of links. Designers aren’t the only ones who make models of sites. Users try to imagine the site structure as well, and a successful information architecture will help the user build a firm and predictable mental model of site. www.ThesisScientist.comWeb Page Structure • A web page constructed using HTML has a basic and essential structure. The page always begins with the start tag of the html element and always terminates with the end tag of the html element as follows: Example 1 html ...web page... /html • All other element tags are 'nested' within the start and end html tags. The web page is then further subdivided into two main sections which are the 'head' and the 'body'. www.ThesisScientist.comWeb Page Structure • The head section begins with the head start tag and terminates with the/head end tag. • Immediately following this comes the body start tag and just before the html end tag comes the /body end tag. • There is only one set of html.../html tags, • one set of head.../head tags and • one set of body.../body tags. www.ThesisScientist.comHow do Web Pages Change • Most pages do not change much. • Larger pages change more often. • Commercial pages change more often. • Past change to a web page is a good indicator of future change. • About 30% of pages are very similar to other pages, and being a near-duplicate is fairly stable. www.ThesisScientist.comLink Analysis • Link analysis is a data-analysis technique used to evaluate connections between nodes. Relationships may be identified among various types of nodes (objects), including organization, people and transactions. • The analysis of hyperlinks and the graph structure of the Web has been instrumental in the development of web search. • Link analysis for web search has intellectual antecedents in the field of citation analysis, aspects of which overlap with an area known as Bibliometrics. www.ThesisScientist.comLink Analysis • Link analysis is an important part of site assessment, either your own or competitor’s. • Outbound links are links on your site which refer to other sites, they go beyond the borders of your site. • Internal links are links which point to another page of your site, i.e. they refer to some place within your site. www.ThesisScientist.comWebsite Navigation Website navigation is important to the success of website visitor’s experience to website. The website’s navigation system is like a road map to all the different areas and information contained within the website. Types of Website Navigation • Hierarchical website navigation The structure of the website navigation is built from general to specific. This provides a clear, simple path to all the web pages from anywhere on the website. • Global website navigation Global website navigation shows the top level sections/pages of the website. It is available on each page and lists the main content sections/pages of the website. • Local website navigation Local navigation would the links with the text of your web pages, linking to other pages within the website. www.ThesisScientist.comWebsite Navigation Use • To be consistent throughout the website. The website visitors will learn, through repetition, how to get around the website. • The main navigation links kept together. This makes it easier for the visitor to get to the main areas of the website. • Reduced clutter by grouping links into sections. If the list of website navigation links are grouped into sections and each section has only 5-7 links, this will make it easier to read the navigation scheme. • Minimal clicking to get to where the visitor wants to get to. If the number of clicks to the web page the visitor wishes to visit is minimal, this leads to a better experience. www.ThesisScientist.comWebsite Navigation Use • Some visitors can become confused or impatient when clicking a bunch of links to get to where they want to be. • In large websites, this can be difficult to reduce. Using breadcrumbs is one way to help the visitor see where they are within the website and the path back up the navigation path they took. • Creating the website navigation system at the planning stage of the website will effect the overall design of the web page layout and help develop the overall plan for the website. www.ThesisScientist.comWeb Mining • Web mining can be broadly defined as discovery and analysis of useful information from the World Wide Web. • Based on the different emphasis and different ways to obtain information, web mining can be divided into two major parts: Web Contents Mining and Web Usage Mining. • Web Contents Mining can be described as the automatic search and retrieval of information and resources available from millions of sites and on-line databases though search engines / web spiders. • Web Usage Mining can be described as the discovery and analysis of user access patterns, through the mining of log files and associated data from a particular Web site. www.ThesisScientist.comWeb Usage Mining • The automatic discovery of patterns in clickstreams and associated data collected or generated as a result of user interactions with one or more Web sites. Goals – To analyze the behavioral patterns and profiles of users interacting with a Web site. – The discovered patterns are usually represented as collections of pages, objects, or resources that are frequently accessed by groups of users with common interests. www.ThesisScientist.comHow to perform Web Usage Mining? • Web usage mining is achieved first by reporting visitors traffic information based on Web server log files and other source of traffic data. • Web server log files were used initially by the webmasters and system administrators for the purposes of “how much traffic they are getting, how many requests fail, and what kind of errors are being generated”, etc. However, Web server log files can also record and trace thevisitors’ on- line behaviors. • Web log file is one way to collect Web traffic data. The other way is to “sniff” TCP/IP packets as they cross the network, and to “plug in” to each Web server.
