Services for Content Creation and Presentation in an Iconographical Digital Library

Title: Services for Content Creation and Presentation in an Iconographical Digital Library<br/><br/>Authors: Pavlov, Radoslav; Paneva-Marinova, Desislava; Goynov, Maxim; Pavlova-Draganova, Lilia<br/><br/>Abstract: Content creation and presentation are key activities in a multimedia digital library (MDL). The proper design and intelligent implementation of these services provide a stable base for overall MDL functionality. This paper presents the framework and the implementation of theseservices in the latest version of the “Virtual Encyclopaedia of BulgarianIconography” multimedia digital library. For the semantic description of theiconographical objects a tree-based annotation template is implemented. Itprovides options for autocompletion, reuse of values, bilingual entering ofdata, automated media watermarking, resizing and conversing. The paperdescribes in detail the algorithm for automated appearance of dependent values for different characteristics of an iconographical object. An algorithm for avoiding duplicate image objects is also included. The service for automatedappearance of new objects in a collection after their entering is included as an important part of the content presentation. The paper also presents theoverall service-based architecture of the library, covering its main servicepanels, repositories and their relationships. The presented vision is basedon a long-term observation of the users’ preferences, cognitive goals, andneeds, aiming to find an optimal functionality solution for the end users.Smartbook: Semantics Inside

Title: Smartbook: Semantics Inside<br/><br/>Authors: Koychev, Ivan; Dicheva, Darina; Nikolov, Roumen<br/><br/>Abstract: This paper presents a vision for the future of the e-books whichentails further development of technologies that will facilitate the creationand use of a new generation of "smart" books: e-books that are evolving,highly interactive, customisable, adaptable, intelligent, and furnished witha rich set of collaborative authoring and reading support services. Theproposed set of tools will be integrated into an intelligent framework for collaborative book authoring and experiencing called SmartBook. The paperpromotes the idea that the semantic technologies, intensively developed recently in connection with the Semantic Web initiative, can be incorporatedin the book and become the key factor of making it "smarter".Semantically Enhanced Software Documentation Processes

Title: Semantically Enhanced Software Documentation Processes<br/><br/>Authors: Klieber, Werner; Granitzer, Michael; Gaisbauer, Mansuet; Tochtermann, Klaus<br/><br/>Abstract: High-quality software documentation is a substantial issue forunderstanding software systems. Shorter time-to-market software cycles increase the importance of automatism for keeping the documentation up todate. In this paper, we describe the automatic support of the software documentation process using semantic technologies. We introduce a software documentation ontology as an underlying knowledge base. The defined ontology is populated automatically by analysing source code, software documentation and code execution. Through selected results we demonstrate that the use of such semantic systems can support software documentation processes efficiently.Cultural Knowledge for Named Entity Disambiguation: A Graph-Based Semantic Relatedness Approach

Title: Cultural Knowledge for Named Entity Disambiguation: A Graph-Based Semantic Relatedness Approach<br/><br/>Authors: Lisa Gentile, Anna; Zhang, Ziqi; Xia, Lei; Iria, José<br/><br/>Abstract: One of the ultimate aims of Natural Language Processing is toautomate the analysis of the meaning of text. A fundamental step in thatdirection consists in enabling effective ways to automatically link textualreferences to their referents, that is, real world objects. The work presentedin this paper addresses the problem of attributing a sense to proper namesin a given text, i.e., automatically associating words representing NamedEntities with their referents. The method for Named Entity Disambiguationproposed here is based on the concept of semantic relatedness, which in thiswork is obtained via a graph-based model over Wikipedia. We show that,without building the traditional bag of words representation of the text,but instead only considering named entities within the text, the proposedmethod achieves results competitive with the state-of-the-art on two differentdatasets.The Global Campus - ICT and the Future of Universities

Title: The Global Campus - ICT and the Future of Universities<br/><br/>Authors: Nikolov, Roumen<br/><br/>Abstract: This paper analyses the changes which the ICT causes on aglobal scale. The globalization of higher education triggered by e-Learning,the emergence of e-infrastructure for e-science, the Open Educational Resourcesmovement, e-libraries and the tendency of building global educationalalliances are analysed as well. Special emphasis is put on several wellknownuniversity models, e.g. Research University, Open University andEntrepreneurial University, as well as on some emerging university modelsfor the Knowledge Society, such as: Global University and InnovationUniversity. The paper puts in focus the influence of the ICTs and thenew organizational and business models they bring, such as Virtual University, eCampus, Enterprise 2.0, University 2.0. A new university modelis defined—the Global Campus Model. Some arguments that the ultimateresult of the ICTs driven transformations could turn the whole world into aGlobal Campus in the next few decades.Technology-Enhanced Learning: Review and Prospects

Title: Technology-Enhanced Learning: Review and Prospects<br/><br/>Authors: Westera, Wim<br/><br/>Abstract: This paper is a reflection on the history and future of technology-enhancedlearning. Over the last century various new technologies wereintroduced in education. Often, educational revolutions were proclaimed.Unfortunately, most of these new technologies failed to meet the high expectations.This paper reviews the rise and fall of various "revolutionary"learning technologies and analyses what went wrong. Three main drivingfactors are identified that influence the educational system: 1) educationalpractice, 2) educational research, and 3) educational technology. The roleand position of these factors is elaborated and critically reviewed. Today,again many promising new technologies are being put in place for learning:gaming, social web, and mobile technologies, for example. Inevitably, theseare once again proclaimed by its supporters to revolutionise teaching andlearning. The paper concludes with identifying a number of relevant factorsthat substantiate a favourable future outlook of technology-enhancedlearning.An Analysis and Forecast of Software and Services Research in Bulgaria

Title: An Analysis and Forecast of Software and Services Research in Bulgaria<br/><br/>Authors: Ilieva, S; Eskenazi, A; Dimov, A; Pavlova, I<br/><br/>Abstract: In the last 40 years much has been achieved in Software Engineering research and still more is to be done. Although significant progress isbeing made on several fronts in Service-Oriented Architecture (SOA), thereis still no set of clear, central themes to focus research activity on. A taskwithin the EU FP7 Sister project aimed at defining research priorities forthe Faculty of Mathematics and Informatics (Sofia University) in the area ofSoftware and Services. A dedicated methodology was proposed and developed, based on various sources of information. The information accumulatedwas systematised and processed according to this methodology. The finalresults obtained are described and discussed here.
