Abstract: AspectJ and several other AOP frameworks allow for aspects to be woven with classes at compile time or at load time. While load-time weaving offers some flexibility, once weaved classes stay that way until application restarts with new aspects to be loaded. Adaptive continuous monitoring built on these frameworks requires periodical restarting of application in order for the new aspect configuration to be loaded. This approach is often very uncomfortable, sometimes even unacceptable. There are applications and systems that are not allowed to be restarted, or are allowed to be restarted very rarely. For these systems, the use of another AOP platform that allows runtime weaving and re-weaving of aspects would be of great importance.

Abstract: Complexity of the software development process has greatly increased compared to early days of software development. Considering that new software development methodologies allow changes in each phase of the process the need for using a change management system is obvious. These systems enable the software development team to respond to customer’s change requirements and changes to the business process and business model while maximizing value and minimizing incidents, disruption and reworking. In this paper we describe the role of change management systems and our practical experience with the change management process in the Solutia s.r.o. company

Abstract: In this paper we present a formal specification of platform independent model (PIM) concepts of the Integrated Information Systems CASE Tool. PIM concepts are described by Graph-Object-Property-Port- Role-Relationship meta-modeling language used in MetaEdit+ meta-modeling environment. Through our previous research we have specified PIM concepts using Ecore implementation of Meta Object Facility 2.0 in Eclipse Modeling Framework. As our goal is to create a formal specification of PIM concepts that designers would later use to graphically specify the structure of an information system, MetaEdit+ was the obvious choice. MetaEdit+ provides an integrated environment for definition of abstract syntax as well as the definition of concrete syntax using graphical symbol editor. In this paper we give an example of information system modeling using specified PIM concepts.

Abstract: Web search has developed from simple information retrieval to complex tools. The same is not yet true for Web information management. Heterogeneous databases are still state of the art and make thorough understanding of content hard. However, small well curated locally focused servers of cultural collections emerge throughout Europe, offering a perfect basis for making a leap in Web information management. Therefore, we propose an innovative way of presenting and accessing the information on the Web. The central concept is that of a personalized storyline offering an organized “tour” through resources. Based on content metadata and on information about uses of a resource, a system would automatically generate storylines fitting users’ requests. But to capture attention story telling alone is not sufficient: humanity is starting to be unable to concentrate deeply onto any one single aspect for any length of time. In addition to the story telling issue we are going to use ideas to capture attention, like showing a cultural artefact with an error or asking a question after a video-clip. We also will tie in the Community deeply into building story lines

Abstract: The amount of data created annually is growing exponentially. Some of the newly created data is important enough to be kept for shorter or longer time, therefore the need for data archiving is growing proportionally to data growth. We designed an efficient and scalable archiving system that can easily be adapted to the needs of different archiving applications and scenarios. A Fast Hash-based File Existence Checking algorithm is the core of the system. It outperforms other algorithms for file uniqueness checking. The proposed archiving system is a distributed processing and storage system that works with metadata hashes and file hashes. We implemented the archiving system in a form of a backup-like application for files on personal computers in the laboratory. The application operational tests yielded very favourable results, for example, the need for archive storage almost halved just because of the elimination of files with exactly the same content. We expect the proposed archiving system will find many uses in the present and future data archiving efforts

Abstract: This paper proposes a novel method for anonymization of judgments, represented in XML format, according to the predefined anonymization rules. The method is based on the access control for XML documents enforced using the XXACF framework. AKOMA NTOSO was used as an electronic format for representation of judgments in order to enable efficient integration of the proposed solution with existing legal information systems.

This paper gives a specification of that web service used for exchange messages and files between BISIS system and Audio library system

Abstract: This paper presents an example for classification of bibliometric indicators. The basics of the CERIF model and one solution of bibliometric indicator mapping to CERIF model are presented. Mapping was accomplished by using the CERIF semantic layer and applying appropriate classification scheme.

Abstract: To be able to cope with all the challenges that are emerging with the rise of the Web of Data, linked data tools must find ways to deal with its heterogeneity with regard to the content being published and the languages that content is being published in. Adequate internationalization support is a must for distributing or consuming multilingual data, but providing it is not straightforward. In this paper, we analyze the problems semantic web tools are faced with when it comes to data being published in Western Balkan languages. We look at resource presentation mechanisms, show how IRIs can solve many of the common problems related to Serbian alphabets, but also that the Semantic Web is still not ready for full transition to internationalized identifiers. We also review different serialization options and explain why most XML-based formats are not suitable for the task of internationalization. To see how popular linked data tools deal with such data, we propose an evaluation methodology, and give an insight into the i18n-readiness of some popular semantic web tools.

Abstract: This paper presents an extension of the CERIF data model, necessary for storing information about scientific projects funded by state authorities in the Republic of Serbia. Based on the set of metadata identified in these projects, a CERIF compatible conceptual model is designed which will be deployed in the common research information system of the University Novi Sad – CRIS-UNS.

Abstract: In this paper we focus on several issues related to slow responsiveness of web sites. Page response time directly correlates to user abandonment, which consequently means a loss of profit. We analyze the whole round trip time (RTT) for each web page, excluding the factors that are not vital for optimization. We concentrate on the main factors behind slow response times and focus on the indicators that can be improved by web hosting providers running a shared hosting environment. In addition, we also describe a fresh approach to benchmarking. It is far better suited for a shared hosting environment using real log files that are already collected in the course of regular traffic. These log files are then used to recreate log traffic in order to perform various tests with different setups. The insights gained from these tests represent the basis for business decisions on infrastructure for the next 3-5 year period.

Abstract: The issues of protecting critical infrastructure, especially telecommunication and information critical infrastructure are in the focus of many governments, regulatory agencies and standardization bodies worldwide. Standardization bodies are trying to establish general model and standard for the protection of critical information infrastructure, but conditions differ from country to country and each one of them must provide its unique model based on general recommendations. In this paper, the possible approach for critical information infrastructure protection in Serbia is presented regarding EU and Serbian standards and regulations. The key stakeholders are identified, and their roles in this process are discussed.

Abstract: Cloud service providers (CSPs) offer a payper-use pricing model which charges the customers according to acquired resources. The quality assurance of such a model is negotiated between the customers and the CSPs via Service Level Agreements (SLAs). However, SLAs almost never guarantee sustainable performance. In this paper we propose a new CSP pricing model that aims towards performance charging, instead of rental. We believe that this model provides the customers maximum performance gain with minimum monetary costs. The methodology we developed is based on machine learning analysis that promise to provide accurate decisions when offering both performance and cost-effective configurations in the cloud.

Abstract: A comprehensive Register of institutions in the fields of culture, education and health is an essential tool for policy and decision making in those fields. Institution can be either completely or partially owned and financed by local, provincial or state government. Therefore, those governmental levels can have various responsibilities in the process of decision making regarding further development, financing and planning in those institutions. In order to successfully perform their duties and exercise their rights in governing those institutions, comprehensive and up-to-date information about those institutions must be available. Appropriate form for storing potentially large amounts of data about those institutions is to build a specialized registry. By opening parts of such a registry to public access, the level of e-government service that local, provincial and state government is providing to citizens can be largely improved. Such an open access can be beneficiary to both citizens as well as professionals in those fields. This paper presents a pilot project of such a registry, developed for Provincial Government of Autonomous Province of Vojvodina. This paper presents overall data model necessary to support such a registry, as well as an implementation of one specialized registry - Registry of health institutions. The presented implementation is entirely based on open source software systems.

Abstract: This paper deals with comparing the efficiency of guided and unguided learning using formal representation of an instructional strategy. Strategies were formally represented with ELIDL – an XML-based language specially designed for this purpose. Three instructional strategies were defined. Two of them, named worked-out examples and process-worksheets, represent guided learning, while the third one represents unguided learning. The efficiency of the strategies was evaluated on the course “Numerical algorithms and numerical software in engineering” held at the Faculty of Technical Sciences at University of Novi Sad. A sample of 81 students was divided into three groups, where each group was given the course created according to different instructional strategy. The results show that the most efficient instructional strategy is process-worksheets strategy.
