The Semantic Web (SW) and Geospatial Semantic Web (GSW) are considered the next step in the evolution of the Web. For most non-Web specialists, geospatial information professionals, and non-computer-science students these concepts and their impacts on the way we use the Web are not clearly understood. The purpose of this chapter is to provide this broad audience of non-specialists with a basic understanding of: the needs and visions driving the evolution toward the SW and GSW; the principles and technologies involved in their implementation; the state of the art in the efforts to create the GSW; the impacts of the GSW on the way we use the Web to discover, evaluate, and integrate geospatial data and services; and the needs for future research and development to make the GSW a reality. A background on the SW is first presented to serve as a basis for more specific discussions on the GSW.

Due to the continuous research and development activities taking place in almost all the disciplines, information overload and information explosion has occurred, which in turn poses a challenge to the user community to keep up with the knowledge in their discipline. The dynamic nature of information has forced the users to change the way of seeking information. Hence, there is an immediate need for the information professionals to update the services and facilities of the library. He/she should act as a ultimate search engine and satisfy the information needs of the users. This chapter highlights the changing approach to information by the user community in the present scenario and also provides the solutions to information professionals to tackle the information expectations of the users. This chapter has been written based on the observation of library users and the way they seek information for their business requirements and research and development activities.

The evolution of the web has transformed the way persons communicate and interact with each other, and has reformed institutional operations in various sectors. Examining these changes through the theoretical framework Connectivism, provides a detailed analysis of how the web impacts individuals' context within communities as well as the larger society. This chapter examines the evolution of the web and the characteristics of various iterations of the web. A discussion on the emergence of participatory media and other participatory processes provides insight as to how the web influences personal and professional interactions. Research on how the web has changed cultural contexts as well as systems such as education, governments and businesses is shared and analyzed to identify gaps and provide direction for future research.

In this chapter, we describe the motivations for, and development of, a rule-based policy management system that can be deployed in the open and distributed milieu of the World Wide Web. We discuss the necessary features of such a system in creating a “Policy Aware” infrastructure for the Web and argue for the necessity of such infrastructure. We then show how the integration of a Semantic Web rules language (N3) with a theorem prover designed for the Web (Cwm) makes it possible to use the Hypertext Transport Protocol (http) to provide a scalable mechanismfor the exchange of rules and, eventually, proofs for access control on the Web. We also discuss which aspects of the Policy Aware Web are enabled by the current mechanism and describe future research needed to make the widespread deployment of rules and proofs on the Web a reality.

The rate of growth in the amount of information available in the World Wide Web has not been followed by similar advances in the way this information is organized and exploited. Web adaptation seeks to address this issue by transforming the topology of a Web site to help users in their browsing tasks. In this sense, Web usage mining techniques have been employed for years to study how the Web is used in order to make Web sites more user-friendly. The Semantic Web is an ambitious initiative aiming to transform the Web to a well-organized source of information. In particular, apart from the unstructured information of today’s Web, the Semantic Web will contain machine-processable metadata organized in ontologies. This will enhance the way we search the Web and can even allow for automatic reasoning on Web data with the use of software agents. Semantic Web adaptation brings traditional Web adaptation techniques into the new era of the Semantic Web. The idea is to enable the Semantic Web to be constantly aligned to the users’ preferences. In order to achieve this, Web usage mining and text mining methodologies are employed for the semi-automatic construction and evolution of Web ontologies. This usage-driven evolution of Web ontologies, in parallel with Web topologies evolution, can bring the Semantic Web closer to the users’ expectations.

The last decade has shown the e-business community and computer science researchers that there can be serious problems and pitfalls when e-companies are created. One of the problems is related to the necessity for the management of knowledge (data, information, or other electronic resources) from different companies. This chapter will focus on two important research fields that are currently working to solve this problem — Information Gathering (IG) techniques and Web-enabled Agent technologies. IG techniques are related to the problem of retrieval, extraction and integration of data from different (usually heterogeneous) sources into new forms. Agent and Multi-Agent technologies have been successfully applied in domains such as the Web. This chapter will show, using a specific IG Multi-Agent system called MAPWeb, how information gathering techniques have been successfully combined with agent technologies to build new Web agent-based systems. These systems can be migrated into Business- to-Consumer (B2C) scenarios using several technologies related to the Semantic Web, such as SOAP, UDDI or Web services.

Abstract We present a systematization of usable security principles, guidelines and patterns to facilitate the transfer of existing knowledge to researchers and practitioners. Based on a literature review, we extracted 23 principles, 11 guidelines and 47 patterns for usable security and identified their interconnection. The results indicate that current research tends to focus on only a subset of important principles. The fact that some principles are not yet addressed by any design patterns suggests that further work on refining these patterns is needed. We developed an online repository, which stores the harmonized principles, guidelines and patterns. The tool enables users to search for relevant guidance and explore it in an interactive and programmatic manner. We argue that both the insights presented in this article and the web-based repository will be highly valuable for students to get a good overview, practitioners to implement usable security and researchers to identify areas of future research.

Abstract Flood protection is one of several disciplines where geospatial data is very important and is a crucial component. Its management, processing and sharing form the foundation for their efficient use; therefore, special attention is required in the development of effective, precise, standardized, and interoperable models for the discovery and publishing of data on the Web. This paper describes the design of a methodology to discover Open Geospatial Consortium (OGC) services on the Web and collect descriptive information, i.e., metadata in a geocatalogue. A pilot implementation of the proposed methodology - Geocatalogue of geospatial information provided by OGC services discovered on Google (hereinafter “Geocatalogue”) - was used to search for available resources relevant to the area of flood protection. The result is an analysis of the availability of resources discovered through their metadata collected from the OGC services (WMS, WFS, etc.) and the resources they provide (WMS layers, WFS objects, etc.) within the domain of flood protection.

Although the majority of Augmented Reality (AR) scholarship is based in Computer Science disciplines, it is nevertheless important to consider emergent trends in AR discourses as research and development shifts from technology labs to media markets. While technical understandings of AR are necessary, they are insufficient to understand how networked spatial computing is augmenting everyday life. In response, this paper maps and compares two specific AR discourses for nodes of power and authority. First, it systematically reviews how AR research citations are shifting from science and technical foci to applied uses of AR via a systematic scientometric review. That work allows, among other insights, consideration of the extent disciplinary boundaries shaped how AR is understood and innovated. Second is contrasting these evolving patterns with current consumer exposure to AR via a critical technocultural discourse analysis (CTDA) of the presentation of phone-based AR apps available on the iOS App Store and Google Play. Comparative discussion of these inquiries adds to understandings of how AR is conceptualised in research and commercial discourses, and how these data might inform future research and practice in the socialisation of AR systems, media, and experience.

The Semantic Web (SW; Berners-Lee, Hendler, & Lassila, 2001) is already in its implementation phase and an indication of this is the intense research and development activity in the area of SW tools and languages. SW is based on metadata, which describe the semantics of the Web content. SW envisages the enrichment of data with semantics in order to be machine understandable and enable knowledge reasoning. The core element for achieving such Web evolution is ontology: “Ontology is an explicit specification of a conceptualization” (Gruber).

The nature of the enterprise and the way people work is changing rapidly. The enabling power and competitive advantage of new social and participative technologies will benefit those that recognize the way work is changing. Web 2.0, the “second phase” of the Web, is the foundation of a new and improved Enterprise 2.0. Enterprise 2.0 provides, through a web of interconnected applications, services, and devices, the capabilities for enterprise employees and vendors to be more competitive and productive and for enterprise customers to be more engaged and loyal by accessing the right information from the right people at the right time. This paper describes Enterprise 2.0 management challenges and issues identified by Chief Information Officers, which include the unauthorized use of services and technologies, the integration of a myriad of technologies and capabilities, and the potential compliance and security implications. The authors have proposed a conceptual framework that explores the relationships of three Enterprise 2.0 dimensions – technology, its use, and how resulting user-generated content may lead to business value – with management implications affecting IT culture and policies within the enterprise. This paper provides observations and suggestions for future research.
