The Web

At the present time, the Web is primarily designed for human consumption and not for computer consumption. This may seem like an unusual state of affairs, given that the web is vast and mature computerized information resource. However, we must recognize that the computer is presently used as the carrier of this information, and not as the consumer of the information. As a result, a great deal of the potential of the Web has yet to be realized. This book explores the challenges of automatic computer-based processing of information on the Web. In effect, we want to enable computers to use Web-based information in much the same way as humans presently do. Our motivation is that computers have a brute-force advantage over humans. Where we can gather and process information from a handful of Web-based sources, a computer may download and compare thousands of such sources in a matter of seconds. Nonetheless, despite the apparent simplicity of this task, there are a great many issues that must be addressed if we are to make effective use of this information. As a result, the automated processing of Web-based information is still in its infancy. In this book, we show how many different techniques can be used together to address this task. The automated processing of information on the Web is principally an issue of scale. There are many existing techniques in Computer Science and Artificial Intelligence (AI) that may be appropriate to the task. However, there are significant issues that must be addressed if we are to scale up these techniques for use on the Web. Therefore, we present a detailed overview of the current state of the art, with a particular emphasis on practical solutions. The methods and technologies that we present in this book are of importance to all computer practitioners, as they will shape the future evolution of the Web. To appreciate the challenges of computer-based consumption of Web-based information, we consider the following scenario. Suppose we are searching the Web for information on a specific ailment.

The Web

At the start of this book we outlined the challenges of automatic computer based processing of information on the Web. These numerous challenges are generally referred to as the ‘vision’ of the Semantic Web. From the outset, we have attempted to take a realistic and pragmatic view of this vision. Our opinion is that the vision may never be fully realized, but that it is a useful goal on which to focus. Each step towards the vision has provided new insights on classical problems in knowledge representation, MASs, and Web-based techniques. Thus, we are presently in a significantly better position as a result of these efforts. It is sometimes difficult to see the purpose of the Semantic Web vision behind all of the different technologies and acronyms. However, the fundamental purpose of the Semantic Web is essentially large scale and automated data integration. The Semantic Web is not just about providing a more intelligent kind of Web search, but also about taking the results of these searches and combining them in interesting and useful ways. As stated in Chapter 1, the possible applications for the Semantic Web include: automated data mining, e-science experiments, e-learning systems, personalized newspapers and journals, and intelligent devices. The current state of progress towards the Semantic Web vision is summarized in Figure 8.1. This figure shows a pyramid with the human-centric Web at the bottom, sometimes termed the Syntactic Web, and the envisioned Semantic Web at the top. Throughout this book, we have been moving upwards on this pyramid, and it should be clear that a great deal of progress that has been made towards the goal. This progress is indicated by the various stages of the pyramid, which can be summarized as follows: • The lowest stage on the pyramid is the basic Web that should be familiar to everyone. This Web of information is human-centric and contains very little automation. Nonetheless, the Web provides the basic protocols and technologies on which the Semantic Web is founded. Furthermore, the information which is represented on the Web will ultimately be the source of knowledge for the Semantic Web.

In this paper we present and discuss the results of the evaluation of an Intelligent Computer Assisted Language Learning (ICALL) system that operates over the Web. In particular, we aimed at evaluating the system along three dimensions: a) the effect of the intelligent features of the system on the learning outcome of students, b) the system's ability to provide individualized support to students that leads to more effective use of the system and c) the general usability and friendliness of the ICALL. To achieve this, we conducted an empirical study, where we compared the intelligent system with a non-intelligent version of it. The results of the study revealed that the students of the Web-based ICALL had gained more knowledge of the domain and had been able to interact with the system more effectively as compared to the students that had used the non-intelligent version of the system. However, the students of the intelligent version of the system found it more difficult and they needed more time to get acquainted with the system in comparison to the students of the non-intelligent system.

The development of mobile devices and the spread of wireless network help share and exchange information and resources more easily. Therefore users are able to use the information and service more free than previous wire network due to development of wireless network and device. In order to provide appropriate user services, it enables to recognize users current state, analyze the users profile like users tendency and preference, and draw the service answering the users request. Most existing frameworks, however, are not very suitable for mobile devices because they were proposed on the web-based. And other context information except location information among users context information is not much considered. Therefore, this paper proposed the context-aware framework, which provides more suitable services by using users context and profile.

We developed a program to estimate an examinee's ability in order to provide freely available access to a web-based computerized adaptive testing (CAT) program. We used PHP and Java Script as the program languages, PostgresSQL as the database management system on an Apache web server and Linux as the operating system. A system which allows for user input and searching within inputted items and creates tests was constructed. We performed an ability estimation on each test based on a Rasch model and 2- or 3-parametric logistic models. Our system provides an algorithm for a web-based CAT, replacing previous personal computer-based ones, and makes it possible to estimate an examinee?占퐏 ability immediately at the end of test.

In the last few years, Web-based surveys have received increased attention given their potential to cut the costs and time associated with paper-based surveys. In this exploratory study, we consider the feasibility of using the Web as a data collection medium in China, which has a current Internet population of 103 million. Following a review of the literature regarding the design, implementation, and application of Web surveys, and the current state of data collection in developing countries in general and China in particular, we describe how we developed a Web-based survey instrument focusing on the ethical values of IT professionals. We e-mailed 5,000 IT professionals in China, inviting them to participate in the survey. Thirty-seven percent of those contacted visited the Web site and 5.8% submitted the survey. The survey data, both qualitative and quantitative, is analysed and discussed with a view to drawing up instructive guidance for researchers interested to use the Web as a data collection tool in China, as well as developing countries more generally. The Web-based survey has great potential in these contexts, if sensitively designed and implemented. We consider the implications of this research and identify areas where future research is necessary.
