“…Scharl's (2001) Extended World Wide Web Design Technique (eW3DT) categorizes a link based on the characteristics of the resource to which the link points. After harvesting links from a Web site, eW3DT classifies each one according to various properties of the target resource, for example, whether the target is on the same Web site as the source and if it shares a superordinate page with the source, whether the target is static or dynamic, and whether the content of the target is determined by external criteria (e.g., a subscription is required to view the target).…”

The number and variety of governmental agencies, businesses, and information providers actively seeking to establish a digital presence on the World Wide Web has underscored the need for "findability" in the design of Web sites. Findability, as defined by Morville (2005), is the ability of users to identify an appropriate Web site and navigate the pages of the site to discover and retrieve relevant information resources. Wurman (1996, p. 16) observes that "The ability to find something goes hand-in-hand with how well it's organized." But locating information resources in the digital environment depends on more than organization. As Morville observes, findability is an inherently interdisciplinary concept that integrates practices of design, engineering, and marketing: Findability encompasses not only issues of organization and representation-two central concerns in the construction of an effective information architecture-but also information seeking behavior, interaction design, branding, search engine optimization, and Web standards, to name but a few of the considerations that can affect findability. The focus of findability is on facilitating and enhancing the user's overall experience with an information resource; information architecture is just one facet of the complex of interactions that contributes to that experience. Information architecture (IA) is, at best, an ambiguous term that came into widespread use with publication of the first edition of Rosenfeld and Morville's (1998) Information Architecture for the World Wide Web. Rosenfeld and Morville describe the primary objective of IA as the provision of effective access to relevant information resources on a Web site. It is precisely this problem of access in digital collections that has propelled information architecture and information architects into the forefront of Web development. For Rosenfeld and Morville, however, the task of the information architect is not simply to provide access to relevant resources on a Web site but also to ensure that a user will have multiple means of access to those resources. To this end, they focus on the systems of navigation, labeling, organization, and searching as the primary elements an information architect uses to specify how users will be able to access information resources.Because of its strong association with Rosenfeld and Morville's book, IA is generally identified with the design of digital environments for the Web. There are those, however, who view IA more broadly. For example, Morrogh (2003, p. 6) describes IA as "the design of information environments and the management of an information environment design process" that finds its origins in a range of fields sharing a common interest in the communication, management, and preservation of information-fields such as computer science, library science, social informatics, and human-computer interaction. He conceives of IA as the summation of a long history of innovations in information and communication technology (ICT)-innovations that are directly ...

“…Observing and visualizing human behavior are common business activities, from tracking customers in retailing outlets to monitoring traffic in congested urban areas or analyzing the clickstreams of online shoppers [13]. Prior to the advent of the Global Positioning System (GPS) and Radio Frequency Identification (RFID), the lack of affordable technology to pinpoint a user's precise location restricted the functionality of many applications.…”

This paper presents the IDIOM Media Watch on Climate Change (www.ecoresearch.net/climate), a prototypical implementation of an environmental portal that emphasizes the importance of location data for advanced Web applications. The introductory section outlines the process of retrofitting existing knowledge repositories with geographical context information, a process also referred to as geotagging. The paper then describes the portal's functionality, which aggregates, annotates and visualizes environmental articles from 150 Anglo-American news media sites. From 300,000 news media articles gathered in weekly intervals, the system selects about 10,000 focusing on environmental issues. The crawled data is indexed and stored in a central repository. Geographic location represents a central aspect of the application, but not the only dimension used to organize and filter content. Applying the concepts of location and topography to semantic similarity, the paper concludes with discussing information landscapes as alternative interface metaphor for accessing large Web repositories.
