State-of-the-art learning management systems provide their stakeholders with many features coming from Web 2.0 paradigm, but often ignore the need for personalization and adaptation during the learning. More, learning activities are often fragmented – a student needs to make a decision whether he or she wants to take questions or read explanatory materials.(More)
In this paper we present an approach to sharing a user model among several adaptive hypermedia applications. Current adaptive hypermedia applications often realize the user model as the internal part of the system without any possibility to share this model with other applications. We introduce a Web service called UMoWS (user model Web service). The Web(More)
The information overloading is one of the biggest problems nowadays. We can see it in various domains, including business, especially in the news. This is more significant in connection to web and news portals, where the quality of the news portal is commonly measured by amount of news added to the site. Then the most renowned news portals add hundreds of(More)
The process of semantic web service composition arranges several web services into one composite service to realize complex workflows with an exploitation of semantics. This paper proposes a framework to automatic semantic web service composition. Its advantage is that a huge amount of computation is performed during preprocessing and the composition(More)
Web service composition is a topic bringing several issues to be resolved. Our work deals with the effectiveness and scalability of service composition. During composition we consider QoS and pre-/post-conditions of single services to create a composite service satisfying the user needs the best. Regarding pre-/post-conditions we propose an approach to fast(More)
Many of software engineering tools and systems are focused to monitoring source code quality and optimizing software development. Many of them use similar source code metrics to solve different kinds of problems. This inspired us to propose an environment for platform independent code monitoring, which supports employment of multiple software development(More)
The social aspects of the group members are usually omitted in today’s group recommenders. In this paper we propose novel approach for the intergroup processes modeling, while the friendship type, user’s personality and the group context is considered in order to reflect the group member influence. Moreover, the bi-directional emotional contagion is(More)
Personalization of web-based information systems based on specialized user models has become more important in order to preserve the effectiveness of their use as the amount of available content increases. We describe a user modeling approach based on automated acquisition of user behaviour and its successive rule-based evaluation and transformation into an(More)
The aim of Web service composition is to arrange multiple services into workflows supplying complex user needs. Due to the huge amount of Web services and the need to supply dynamically varying user goals, it is necessary to perform the composition automatically. The objective of this article is to overview the issues of automatic dynamic Web service(More)
