....the products and services they search for. This raises the following issue: how can a Web based system support these customers in finding the goods best fulfilling their needs To face this issue, several Web based systems offer one to one recommendation of items, given the customer s preferences [1, 2, 7, 10, 13, 15]. However, the recommendation techniques developed so far do not support the configuration of items, that is essential to comply with the customer s requirements when purchasing complex products, or registering for services. At the current stage, this type of activity can be performed by using ....

....with numerous dilemmas. Recommender Systems [1] can guide the user through these processes by recommending paths, solutions, alternatives and new ideas. Recommendation in most cases is regarded as an extension of the prediction process that frequently takes place in User Modeling Systems [2] [3] instead of predicting a single item of a user s profile based on other information, a whole set of items is predicted in a similar fashion. The predicted items will thus play the role of items to be recommended to the user. In the remainder of the article we will explore two key approaches to ....
....given the selections a particular user has made. In fact, recommender systems can be regarded as information agents who serve their users, trying to provide them with the information that best serves their needs. Personalization has been identified as a primary objective of many online systems [3]. 2.2 Existing Techniques There are a number of techniques used for the design of a recommender system. We can categorize these techniques as Content Based, Social or Collaborative, and Hybrid. Content Based Techniques In content based techniques, the user model includes information about the ....

.... for hypermedia in the automation of some tasks related to hypermedia creation and management [6] The research field of adaptive hypermedia is also relevant to our approach in that it studies the use of semantic relations for tailoring the hypermedia to a specific user; in particular, works by [3] and [2] have investigated many relevant issues. By the same token, our previous work done on Macronodes [5] provided an important stepping stone to our research in that it analyzes the structure and annotation of texts for a multimedia presentation. 5. ACKNOWLEDGMENTS This work has been ....

....(this is achieved with sensors in VRML) and (ii) assemble files of 3D content starting from parametric descriptions of 3D models (this is achieved with PROTOs in VRML) 2. 1 The Adaptation Problem and VRML In general, the problem of making a system adaptive can be broken down into three tasks [11]. The acquisition task is concerned with (i) identifying available information about the user, either by monitoring the system usage or by obtaining information from external sources, ii) making this information accessible to the adaptation component of the system, and (iii) building an initial ....
....3D e commerce has still to face major challenges (e.g. browser compatibility issues, navigation and usability issues, and needs to be provided with proper tools to develop effective Web sites and use them. For examp le, while for 2D e commerce both specific research about adaptivity (e.g. [1, 2, 9, 11, 12, 13]) and commercial developer tools for building adaptive Web sites (see [9] for a review of them) are available, the relevant issue of personalization in 3D e commerce has yet to be faced. From this point of view, providing the application developer with tools for personalization (as it is typical ....

.... used to attract the customer s attention to (new) information, products and services; it can be used to persuade customers to purchase a certain product directly or to live according to a certain lifestyle; and it can be used to o#er reassurance and service to keep the customer satisfied and loyal [5]. In order to automatically generate web based presentations which help users to fulfill their needs and to become loyal customers, a complex model is needed. This model should not only contain the information about the user, but also about the setting in which the presentation will be presented. ....

....attributes constitute the personal student characteristics. Directly asking students to provide information about themselves is one of the most obvious methods of acquiring information. However, self assessment is error prone, since users are often not correctly aware of their own capabilities [18, 19, 20]. Therefore, similarly with ELM ART II [21] Web EasyMath also uses a preliminary test in order to assess the knowledge level of the student conceming the domain of algebraic powers, as well as simple arithmetic operations. In particular, the preliminary test contains questions that are related to ....

Following Kobsa s classification [11], the adaptation production has been oriented to the generation of contents and structures adapted on the basis of a given user model Figure 1. A portion of the home page of the English version of E tool (http: www.e tool.it OfficeEng ) We divided our personalization process into these three ....

However, self assessment is errorprone, since users are often not correctly aware of their own capabilities [11, 12]. Therefore, similarly with ELMART II [13] Web PVT also uses a preliminary test in order to assess the knowledge level of the student in the domain of the passive voice of the English language. In particular, based on the student s performance on the preliminary test, Web PVT assigns the student ....

.... (like providing data about themselves) if they do not receive immediate benefits, even when they would profit in the long run [5] Privacy concerns of Internet users This current practice of data collection and processing in personalized hypermedia systems, specifically in personalized websites [23], seems to be in conflict with privacy concerns of Internet users. These became manifest in numerous recent consumer polls, where respondents reported: being (very) concerned about threats to their privacy when using the Internet: 81 [35] 87 [7] being extremely or very concerned about ....
