Since the Web is becoming the main means of disseminating information in private and public organizations, both at internal and external levels, several applications at Internet and intranet level need mechanisms supporting a selective access to data available over the Web. Through XML, the document exchange and acquisition processes, which can be very frequent in Web-based systems, are simplified and standardized. The development of suitable security policies for both access control and information release and distribution are relevant research topics in the security field, and XML compatibility is an important requirement for Web datasource protection. This chapter covers the issues related to the definition of security policies, models and mechanisms for access control and dissemination of Web data, and is organized in two parts. In the first part, we introduce the general issues and requirements related to the definition of different types of security policies for access control and for information release in Web datasources. Then, we present security policies and mechanisms specifically devoted to the protection of XML data. In the second part, we describe the use of XML for the specification of security relevant information, focusing on security policies, subject credentials, and content protection.

The language history questionnaire (LHQ) is an important tool for assessing the linguistic background of bilinguals or second language learners and for generating self-reported proficiency in multiple languages. Previously we developed a generic LHQ based on the most commonly asked questions in published studies (Li, Sepanski & Zhao, 2006). Here we report a new web-based interface (LHQ 2.0) that has more flexibility in functionality, more accuracy in data recording, and more privacy for users and data. LHQ 2.0 achieves flexibility, accuracy, and privacy by using dynamic web-design features for enhanced data collection. It allows investigators to dynamically construct individualized LHQs on the fly and allows participants to complete the LHQ online in multiple languages. Investigators can download and delete the LHQ results and update their user and experiment information on the web. Privacy issues are handled through the online assignment of a unique ID number for each study and password-protected access to data.

Facebook, like any other social networking site, troubles the traditional categories of private and public spheres. As it complicates (and transcends) the distinction, it can be called a different space, or a liminal space, which falls somewhere in-between private and public spheres. The author argues that this recognition of Facebook as a liminal sphere has important implications to the (re) definition of public and private spheres and to the ways rhetoric should work or be used in the Web 2.0 sites like Facebook. The author also proposes that Michael de Certeau's notions of “strategy” and “tactics” can be powerful rhetorical tools to deal with Facebook's liminality and to enhance the rhetorical performance of self in Facebook and other similar new media forums.

University portals are emerging all over the world. Portals have been perceived by many people as the technologies that are designed to enhance work and learning processes at university by making workflows simpler and information more readily available in a form in which it can be processed (Franklin, 2004). There are many benefits for having a portal in a university. First, the portal makes it easy for people to find university information targeted specifically at them. Instead of the user searching the Web for information, a person identifies himself or herself to the portal, and the portal brings all relevant information to that person. Secondly, the portal uses a single consistent Web-based front end to present information from a variety of back-end data sources. Although information about people is stored in many different databases at a university, the role of a portal is to put a consistent face to this information so that visitors do not have to deal with dozens of different Web interfaces to get their information. Usability is an important issue when designing the university portal. Principles from human computer interaction must be included in the design of portals.

The Web

Huge volume of information is available in the WWW. However, the demand is on relevant information rather than available information, which are often heterogeneous and distributed. Agriculture is one such domain, which includes information like soil, crops, weather, etc., under one roof. This information is in different representations and structures e.g. weather. This scenario leads to a challenge that how to integrate the available and heterogeneous agricultural information to deliver better production. The information on the web is syntactically structured but, the need is to provide semantic linkage. The semantic web supports the existing web to easily process and interpret information. In this paper, a semantic based Agricultural Information System (AIS) is proposed which addresses heterogeneity issues among weather systems and integrates information like soil, weather, crop and fertilizers. AIS helps the farmers regarding the type of crop/soil, crop/climate, fertilizer applications, diseases and prevention methods using effective retrieval of information from integrated systems.

Purpose – The purpose of this paper was to study users’ behaviour when using different search engine results pages (SERPs) to identify what types of scents (cues) were the most useful to find relevant information to complete tasks on the Web based on information foraging theory. Design/methodology/approach – This study has designed three interface prototypes and conducted a qualitative study using the protocol analysis methodology. The subjects were recorded and videotaped to identify patterns of searching behaviours on visualization interfaces of SERPs. Findings – The study found that users found titles of categories or websites, keywords of categories, orientation of results and animation are strong scents that users follow to help find information on SERPs. If certain scents are not used followed on an interface, then their strength will diminish. Furthermore, the study showed that simple scent trails are more important to users than complicated trails. Originality/value – This study uses a qualitative approach to explore how users behave with different SERP formats, particularity a visualization format, and identify which scents on the interface are important for users to follow to successfully complete tasks on the Web.

Security in web-based systems that handle confidential information can be considered a particularly sensitive subject that requires assuming some responsibilities about security. Achieving a secure web application involves tackling several issues such encryption of traffic and certain database information, strictly restricted access control, etc. In this work we focus on detecting misuse of the web application in order to gain unauthorised access. We introduce an Intrusion Detection component that by applying Text Categorisation is capable of learning the characteristics of both normal and malicious user behaviour from the regular, high-level log entries generated by web application through its application server. Therefore, the detection of misuse in the web application is achieved without the need of explicit programming or modification of the existing web application. We applied our Intrusion Detection component to a real web-based telemedicine system in order to offer some evaluation measurements. This articles offers an overview of the model, our experiences, and observations.

The Web

In recent years, the usage pattern of the Web has been undergoing dramatic changes. The traditional definition of the Web, “a system of interlinked hyper-text documents”, can no longer describe the situation accurately today. Instead, users want to interact with Web resources and even want to create their own Web resources that can interact with others. This is what we call “Web 2.0”, a new Web that is both read-able and write-able. However, considering Web-based services around us: the calendar services, the traveling services, and the messaging services, etc., one can draw a conclusion that what Web users nowadays expect from the Web are not only contents and interactions but also services. To meet this expectation, a read/write/execute-able Web is demanded. In this paper, new technologies for building such a Web are proposed. A virtual browsing environment is employed to transform existing Web resources into executable services. Furthermore, an HTML-to-XML annotation/transformation technology is integrated into the virtual browsing environment to form the data model part. With these technologies, the Web will be transformed into “a system of interlinked services.”
