Title: Advanced Approach for Effective Verification of Component Based Software Systems Authors: Pavlova, Irena; Dimov, Aleksandar Abstract: The development of complex systems based on reusable components has many advantages such as lower costs and shortened development lifecycles. At the same time this innovative approach continues to place significant challenges towards integration and testing of such systems. The paper analyses the difficulties of components testing and proposes a combination of Built-In-Testing, Aspect Oriented Software Development, Test Driven Development and Test Governance to realize a method for effective verification in component based systems.

Title: Storyboard Design for Adaptive E-learning Based on Learning Styles Authors: Vassileva, Dessislava Abstract: The article discusses the methodology taken for instructional design of adaptive courses based on learner character such as learner goals and preferences, learner style and, as well, learner performance and satisfaction level. The adaptive course is presented by storyboard graph, whose nodes are pages with learning content, but paths in it represent different pedagogical strategies set by the instructor. This approach was used in ADOPTA - adaptive technology enhanced platform for edutainment, in order to develop a course on XML. It is consistent with a new conceptual model for adaptive hypermedia and uses a family of Honey and Mumford learning styles.

Title: Query-Based Summarization: A survey Authors: Damova, Mariana; Koychev, Ivan Abstract: This paper presents a survey of recent extractive query-based summarization techniques. We explore approaches for single document and multi-document summarization. Knowledge-based and machine learning methods for choosing the most relevant sentences from documents with respect to a given query are considered. Further, we expose tailored summarization techniques for particular domains like medical texts. The most recent developments in the field are presented with opinion summarization of blog entries.

Title: SesameTM: Building Topic Maps on RDF Authors: Bleier, Arnim; Bock, Benjamin; Maicher, Lutz Abstract: Over the past decade RDF has developed to become the dominant standard for representation and interchange of structured data on the web. In portal development, widely unrecognized by Semantic Web research, subject-centric topic maps are actively used and have evolved from an ancient SGML and intermittent XML-based standard to a pure data model. This data model can be represented as a graph and served various integration strategies, put forward over the past years, as a starting point. However, none of these strategies really appreciates the way in which the technologies are used resulting in a poor tool interoperability. To overcome this state we propose a Topic Maps engine acting as congurable wrapper for Sesame. The software library we develop and describe in this paper implements the Topic Maps Application Programming Interface (TMAPI) enabling the usage of Topic Maps infrastructure instead of working at the level of RDF triples.
