Reliability and correctness of a web application are crucial factors to its success. Errors occurring in non-deterministic moments do not attract the target audience of the application. It is quite impossible to deliver 100% reliable application. Hidden errors are discovered when target users are using the application. With proper tooling and support the time between the error discovery or report and the error elimination can be reduced. In this paper we are proposing formal model for a model based improvement of a testing process of the web application. Our goal is to create a formal model and design a testing framework based on the direct guidance of a tester through the testing process, verifying his steps and providing better feedback.

Peer-to-Peer (P2P) approach in information retrieval systems has drawn significant attention recently. P2P networks provide obvious advantages like scalability, reliability and, therefore, recent researchers are looking for a way to adapt these techniques to Information Retrieval fashion of nodes with heterogeneous documents. The greatest attention is paid to different semantic-based searching such as Gnutella Efficient Search (GES) proposed by Zhu Y et al., which derives from Vector Space Model. This paper proposes conceptual design of P2P unstructured information retrieval (IR) with heterogeneous documents on independent nodes. [ABSTRACT FROM PUBLISHER]

The proposal is focusing on situation in web-based application development lifecycle, where potential errors and non-optimalities can be efficiently detected and corrected during the phase of analysis and design. The proposal is based on general formal model, compatible with common UML-based analytical and design models. Based on this model, we propose several verification techniques discovering either design errors or non-optimalities related to real usage of the implemented application. The verification process is constructed to be performed systematically, time efficiently and in an automated way. [ABSTRACT FROM AUTHOR]

Adaptive hypermedia system stores information about user and adapts its behavior due to this information. We can adapt user interface of the system or the documents provided by the system. The major drawback of this promising technology is a low reusability of adapted content. Attempts to improve the reusability of the content are often based on the design of some standard, which is difficult to implement in existing systems, because a change of the system is needed. Our aim is to design a solution, which allows transformation of content between the systems without necessity to change them. Technically, it is special application, which is connected to the content repositories of the integrated systems and performs the transfers of the content driven by the mapping rules.

The fundamental standards for semantic web (RDF and OWL) and tools that work with them, were deployed recently as a result of strong effort of the semantic web community. Today, applications and metadata should be produced to enable the semantic web vision of a universal medium of data exchange. A large number of current web resources that should be semantically annotated are dynamic websites generated from databases. A successful mass production of metadata to extend these web resources, requires tools that will make RDF publishing as simple as HTML publishing. As an answer to this challenge we propose the two-layer mapping model of a database schema to an ontology structure for dynamic RDF metadata production. The main goal of our approach is to propose a flexible, but still simple programming interface that should simplify the work of semantic web presentation developers. [ABSTRACT FROM AUTHOR]

The idea of the Semantic Web is to add computer-readable meaning to the data on the web to extend its possibilities. Large part of data on the Web is stored in relational databases, so it is logical to generate content of Semantic Web directly from these data sources. In this paper we present METAmorphoses - two layer model of ontology based mapping of SQL to RDF. Our mapping model is designed to be an easy-to-use tool for common programmers of Web presentations.

This article deals with formal description of the adaptive web system. Adaptive web system monitors particular user's behavior and characteristics. Based on them, the system compiles resultant, adapted, document. This document corresponds to user's qualification, capability, preferences and his specific needs. Formal description of adaptive web system is needful for exact description of adaptive document behavior, automated implementation of adaptive web systems and next research (e.g. levels of adaptivity which is suitable for users).

"Adaptivity" is a feature of hypermedia that enables to adapt the page contents to the user's needs. In particular, adaptive hypermedia may be applied to computer-based learning environments. In this paper we discuss the problems of developing educational adaptive hypermedia based on XML and RDF. In particular XML is used in order to define two different markup languages to describe the structure of the domain model and the user model. [ABSTRACT FROM AUTHOR]

An adaptive web application (also known by term adaptive hypermedia system) changes dynamically its output in correspondence to specific information of particular user, stored in his profile. This information in profile can be altered via feedback functionality during the run of the system. The technology of adaptive web is one of the promising future Internet technologies. However, this technology has also its drawbacks. One of them is possible user confusion connected with changes in system interface. When working environment changes too much, user is confused and reacts negatively. In this paper, we propose a solution to this problem by defining an automated algorithm to change calibration in adaptive hypermedia system. [ABSTRACT FROM AUTHOR]

Adaptive hypermedia systems can be used in E-learning to improve efficiency and ergonomic quality of producing information. E-learning adaptive hypermedia system stores information about particular user in his profile and adapt its output in correspondence to user's state of knowledge, preferences or specific needs. In contemporary state of area, the most experimental adaptive systems are closed and possibility of e-learning content interchange between systems is not solved satisfactory. For that reason, this paper deals with problem of creating of reusable adaptive hypermedia content using two established e-learning standards, AICC and SCORM. Principles of e-learning standards usage in adaptive hypermedia systems are presented and pilot project implementation introduced. [ABSTRACT FROM AUTHOR]
