Alexandros Kontarinis, Claudia Marinica, Dan Vodislav, Karine Zeitouni, Anne Krebs, Dimitris Kotzinos – Towards a Better Understanding of Museum Visitors’ Behavior through Indoor Trajectory Analysis

Abstract. Nowadays, electronic museum guides have evolved to a point that can act as navigational and informational devices in the museum context; thus they also enable the collection of large volumes of spatiotemporal visitor movement data, from which individual visitor trajectories can be extracted and analyzed. These trajectories have individual characteristics expressed through unique semantics in each museum context (based on the museum, its exhibits and its visitors) and they are restricted in an indoor environment that provides additional constraints. This work presents the benefits, the challenges, and a direction for studying museum visitor movements through context-aware indoor trajectory modeling, mining and analysis.

Olga V. Kirillova – Scopus Database as a Source of Representing Bulgarian Science to the International Academic Community: The Present and Future Prospects

Abstract. The assessment of research performance using international abstract and citation databases, or so-called global citation indexes, is currently the key criterion against which the advance of science is measured practically in all countries. In 2004 the publishing company Elsevier launched a new database – Scopus, which became a major competitor with the reputable resource Web of Science operating since 1964. Developing very successfully, Scopus has become the leading and largest abstract and citation database in the world. The indicators and data provided by Scopus are used in international university rankings and, in general, in the performance assessment of researchers, scientific schools, organizations and countries all over the world. The sources of such information are publications coming from over 150 countries, both from leading international journals and publishing houses, as well as from regional titles indexed in international data-bases. This paper sets out to characterize the Scopus database as a whole, along with its categories and inclusion criteria. Bulgarian Scopus publications and titles are analyzed, with the information about 48 Bulgarian journals reviewed for inclusion and included in Scopus given. The number of Bulgarian journals included in Scopus is expected to rise, provided that international publication standards and Scopus requirements are met.

Еlena Pavlovska – Digital Object Identifier (DOI) – an Important Element in Scientific Communication

Abstract. Digital object identifier (DOI), which appeared in the late 1990s, allows users to immediately find on the Internet the digital object they are interested in – an article, book, journal, dissertation, etc. Nowadays the DOI technology is widely used by foreign publishers. The availability of DOI in scientific documents, as well as the inclusion of DOI in bibliographic references in the literature, has already become a mandatory requirement for journals indexed in the Web of Science and Scopus databases. Unfortunately, DOI is included only by some journals published in Bulgaria. The article presents some new opportunities which DOI opens not only to scientific journals, but also to authors

Feng Zhao, Soo Choon Loy – A Practical Approach to Ascertaining the Accuracy and Resolution of Post Rendered 3D Models Acquired Originally via 3D Digitization

Abstract. 3D digitization is becoming the norm in the preservation of tangible cultural properties be it movable or immovable. In the case of mobile cultural objects, 3D models are normally acquired through non-destructive methods such as photogrammetry or 3D scanning using structured light or laser. The continuing improvements in scanning equipment which result in higher accuracy and resolution can be translated to mean higher level of 3D data acquired. At times, the quantity of 3D data of a single model can get too large and beyond what a normal workstation can process. This is where optimization comes in. However, the level of optimization will vary to suit the final purpose or usage of the 3D model. During optimization, the resulting optimized 3D model is bound to suffer from some level of data loss when compared to the original 3D model acquired directly from laser scanning. This paper discusses a practical method devised by Amber Digital Solutions in maintaining a high level of accuracy of the final optimized model for national archival purposes which requires the highest form of quality.

Magdelena Stoyanova, Lilia Pavlova – Deep Belief Networks for Multimodal, Images-based Non Contact Material Characterization

Abstract. Our growing cognisance about the chemo-physical properties of electromagnetic waves and of their interaction with various materials provides expanding range of possibilities for quantification and non contact material characterization even in difficult to computation, « non-standard » domains as this of the cultural heritage. This review - thematically part of the IFIDA project dedicated to digitization of archaeometric and conservation-restoration praxis - deals with the possibilities latest neuroinformatic methods offer for a more efficient and fast interrogation, understanding and classification of multi-modal spectral records of paintings on various supports. The workflow followed during their routine non destructive (ND) analysis by human experts is described in terms of specific technical characteristics, research objectives and concrete application for the artworks' characterization as a prototype to simulate artificially. References to techniques for high semantic level information extraction from low-level features are suggested. The strengths and limitations in application of Deep Belief Networks (DBNs) for compression, visualization and data recognition are also considered. Examples of most appropriate architectures and topological maps of Deep Learning Networks for interpretation of UV, IR, XR, β, γ and CT records performing simple characterization and classification tasks - from single layer perceptron to multi-layer deep belief neural networks for unlabelled data - are presented and explained.

Darina Ilieva, Gabriela Vaptzarova – Research Project for the Preservation of the Cultural and Historical Heritage

Abstract. The exceptional contribution of Felix Kanitz to Bulgarian scientific and cultural development is an occasion to present to Bulgarian and European public his artistic and documentary heritage, to turn again our attention to the personality and the significant achievements of the great explorer of the Balkans in the 60s and 70s of the nineteenth century. Kanitz`s imagery and literary heritage belong to the most valuable elements of our material and spiritual culture. In the prospect of association of our society to the European community Kanitz`s works should be understandably promoted in the scientific space so as to point out Felix Kanitz`s cultural contributions to Bulgaria and to better identify his relationship with both the national Bulgarian identity and the Balkans and European nations. The artistic works and literary heritage of F. Kanitz which have been preserved until today are valuable elements of the common European material and spiritual culture. The time has come for them to be presented correctly in the scientific world and through the new communication technologies to become available for the public. The Scientific Archive and the Central Library of BAS have a mutual project for specifying and broadening the knowledge about the life and work of Kanitz, and for digitalizing and publishing pages of his private archives. This is a responsible researchers` task which has an important significance for affiliating the Bulgarian culture into European cultural environment.
