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.

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.

The digital recording of Cultural Heritage (CH) and its metadata relates to the concept for data warehousing systems and their lifecycle. It uses models and development tools of ETL packages. The tasks used to extract metadata from raw digitized CH data often include hard computing problems, including NP-complete problems. This paper describes the current state of digital preservation of Cultural Heritage with an accent on data integration and performance optimization of processes. We show our vision for further solutions for automated optimization of resource utilization in ETL jobs cutting development cost. In parallel, we describe our experiment that uses quantum computation (in simulation mode) to solve hard combinatorial problems as multiple query optimization.

The reported evaluation of the problematic encountered by non-contact characterization of natural dyestuffs demonstrates that practically no one analytical method alone – destructive, less, or non – can warrant absolute reliability of the results. The main obstacles are due, in general, to our limited knowledge on reactivity of natural compounds, their sources, methods of proceeding and application; to the complexing role of the ambient/medium on the photo reactions, as well as to the actual possibilities of analytical techniques; to the lack of commonly accepted standards among different scientific traditions, etc. For to overwhelm these drawbacks and optimize accuracy of NDs characterization, we propose the integration of chemio-physical with computational assessment. The proposed approach consists in calculation the probability of a hypothesis comparing new results with already stored interdisciplinary data using the high performance ensemble techniques Random Forest and Random Subspace based on the genetic approach termed EV-Ensemble approach. Its role is to render more accurate the analytical results, to avoid sampling and simplify the identification analysis, to facilitate interdisciplinary applications of NDs in high technologies, and to share generated experience between the research community.

The priceless knowledge from the scientific periodicals, published by Bulgarian museums, has fallen into oblivion over the years. In the era of electronic information, the opportunity arises this once lost knowledge to be made Open Access - free of all restrictions on access. Upon digitilization and correct annotation of the museum paper editions followed by providing them on the Internet for free access, there will be offered scope for a more comprehensive study of the Bulgarian cultural heritage, an integral part of which are the works of its researchers. Registering content in platforms such as Europeana / Bulgariana and setting common standards to facilitate finding the information will be the next challenge for the followers of the idea of cultural heritage digital repositories.

Over the last thirty years, the art enters into a new era of artistic mass production caused by two major developments. The first is the raise of the digital technologies for production of images and objects, while the second is a change in the understanding of what is art, changing the rules by which something is recognized as art or not. Digital technology reshaped completely the way we design and perceive artistic works.

While websites are of great interest for digital archives, the digital long term preservation of websites is a huge problem. The reason is that websites consist of a large number of file formats and require today’s hardware and software environment to work properly. PABLO is a software tool that processes websites and transforms them into a dramatically simplified form that is simple enough for digital archiving and exhaustive enough to preserve the websites content and appearance and allows users to browse the entire site like the original.

The huge amount of digital cultural heritage data is growing every day thanks to the digitisation programmes carried out by cultural institutions. These data should continue to be available in the future to anyone who wishes or needs to access them. This is a very important challenge memory institutions have to face nowadays, and several questions need to be answered to this regard: How will we ensure the long-term preservation and access to our digital information? Who should select which digital data should be saved? How will we successfully store and migrate data as technology evolves? Understanding of digital preservation requires consideration of two main aspects: organisation and technology. Several projects have been funded in the last years to work on these topics by the European Commission. This paper presents the work that is being carried out in two of these projects: DCH-RP and PREFORMA.

In this paper, we give an overview on the emerging trend of the digitized self, focusing on visual lifelogging through wearable cameras. This is about continuously recording our life from a first-person view by wearing a camera that passively captures images. On one hand, visual lifelogging has opened the door to a large number of applications, including health. On the other, it has also boosted new challenges in the field of data analysis as well as new ethical concerns. While currently increasing efforts are being devoted to exploit lifelogging data for the improvement of personal well-being, we believe there are still many interesting applications to explore, ranging from tourism to the digitization of human behavior.

The paper presents the newest developments in integrating Bulgarian Iconographical Digital Library (BIDL) and the tourist mobile application family named as (GUIDE@HAND). The integration made it possible for collections to be created by the user at the BIDL Web page and then downloaded to the GUIDE@HAND Veliko Tarnovo application by using QR codes. This year, a new standalone offline mobile application (BOOK@HAND) was created providing information on icons available in BIDL where the collection presentation functionality of the former system was enhanced with new features. The main novelty of the application is the option to present collections in a virtual exhibition room by using panorama pictures in off-line mode.

Information and multimedia technologies that have been developed during the past couple of years provided new e-tools to memory institutions (viz. museum, libraries, galleries, etc.), reviving the valuable treasure made by generation of people. Digital libraries (DLs) are such powerful contemporary tools for cultural heritage presentation, preservation and archiving. However, DLs power will increase significantly if they use mechanisms for ubiquitous sharing of their e-artefacts and they distribute attractive content in the social networks, reflecting community demands and needs. This paper presents a service for automatic sharing of iconographical artefacts and full collections from the Bulgarian Iconographical Digital Library to selected Facebook communities. In this case the service will be used for widely promotion of knowledge about East-Christian Iconographical Art and Culture, but I could be used not only for this and not only in this domain.

In easel painting (icons) mapping the status of conservation (MCS) is a complex process of prospecting in various spectral, graphic, and spatial techniques, integral analysis and “technical” visualizations of the data whose function is to lay out detected damages or symptoms, not directly perceivable from the VIS, UV, IR or X-r imaging. In this work, the results of a multi-methodological survey applied to the end of detecting sharp discontinuities (boundary of cavities, wrinkles and fractures in the host medium) are illustrated. As, due to the microscopic size and depth of a crackle/wrinkle fragment or net, it may be rather difficult to single out its position and extent because of the generally low signal-to-noise (S/N) ratio, binary image segmentation and high-resolution data acquisition has been adopted for improving the visibility of the studied area.

This paper discusses an implementation of a multimedia projection system with two synchronized video sources, based on the Raspberry Pi singleboard computer systems. The system is primarily intended for various projections in presentation of historical and cultural heritage, although it can be used for many other related purposes. The considered multimedia system has two projection surfaces - a horizontal projection plane and a 45° inclined special glass projection plane which creates the hologram-like Pepper’s Ghost effect. Each plane displays a separate high-definition video obtained from the corresponding Raspberry Pi. Synchronization of presentations is achieved using custom connection through the general purpose input/output (GPIO) connector of the Raspberry Pi and the wiringPi interface library. As valuable aspects of the system, we can point out the following. From the practical point of view, the system has low cost due to the use of Raspberry Pis. Generation of a holographic effect, as well as larger flexibility in creating the contents of the presentations due to the two projection surfaces, are additional attractive features.

This paper considers problems related to the development of knitting software for manual knitting. The support of error handling in knitting software is important for the users. The paper introduces an XML-based approach which allows recreating limitations due to the knitting technology. Each of them represents a Rule which contains certain conditions. One condition describes, allows or doesn’t allow combinations of stitches. The XML-based limitation scheme is developed for building on CAD systems for manual knitting. The users of such software applications could be: people who are interested in knitting as a hobby; editors of knitting hobby magazines; ethnographers who deal with the area of old traditional costumes and manual knitting.

Technical visualizations (TV) of easel painting, both partial or extended, are typically concerned with prospecting its structure, technique, material composition and eventual posterior interventions in order to facilitate the mapping of its characteristics being identical to those of other similar objects. For both types the main challenge is being able to integrate and compare the significant increase in the quantity and quality of image-based data resulting from rapid technological advancement in recent years. Their second critical component matches the algorithm of logical processes that, in principle, should be followed by analysis of a specific artistic technique on a unique artefact. The third crucial point is the translation of interdisciplinary to schematic or imagebased data and the standardization of dictionaries used to enable their sharing. TVs are functional to the understanding of complex cases and, although the reliability of their issues is not absolute but only a nulla osta, they represent an important step towards the drastic reduction of errors produced by discontinued, fragmentary experiments in dating and authentication of easel painting.

PRELIDA (PREserving LInked DAta) is an FP7 Coordination Action funded by the European Commission under the Digital Preservation Theme. PRELIDA targets the particular stakeholders of the Linked Data community, including data providers, service providers, technology providers and end user communities. These stakeholders have not been traditionally targeted by the Digital Preservation community, and are typically not aware of the digital preservation solutions already available. So an important task of PRELIDA is to raise awareness of existing preservation solutions and to facilitate their uptake. At the same time, the Linked Data cloud has specific characteristics in terms of structuring, interlinkage, dynamicity and distribution that pose new challenges to the preservation community. PRELIDA organises in-depth discussions among the two communities to identify which of these characteristics require novel solutions, and to develop road maps for addressing the new challenges. PRELIDA will complete its lifecycle at the end of this year, and the talk will report about the major findings.

In this paper, we consider the task of recognizing epigraphs in images such as photos taken using mobile devices. Given a set of 17,155 photos related to 14,560 epigraphs, we used a k-NearestNeighbor approach in order to perform the recognition. The contribution of this work is in evaluating state-of-the-art visual object recognition techniques in this specific context. The experimental results conducted show that Vector of Locally Aggregated Descriptors obtained aggregating SIFT descriptors is the best choice for this task.

Holography enables capture and reconstruction of the optical field scattered from three-dimensional (3D) objects. The hologram encodes both amplitude and phase of the field under coherent illumination, whereas photography records only the amplitude by incoherent light. 3D visualization feature of holography motivates expansion of research efforts dedicated to digital holographic imaging methods as a holographic display or a holographic printer. The paper presents two holographic 3D printing techniques which combine digital 3D representation of an object with analog holographic recording. Generation of digital contents is considered for a holographic stereogram printer and a recently proposed wavefront printer. These imaging methods could be applied to specific artifacts which are difficult to be recorded by conventional analog holography.

This paper views the problems related to the development of knitting software for hand-made knitting. It presents an XML approach for digital representation of knitting patterns. Its purpose is to develop a uniform and platform independent description of simple graphics primitives corresponding to different types of stitches. The XML language can be built on CAD systems for handmade knit-ting. The users of these software applications could be: people, who are interested in knitting as a hobby; editors of knitting hobby magazines; ethnographers, who invest in the area of old traditional costumes and hand-made knitting.

Information and multimedia technologies that have been developed during the past couple of years provided new e-tools to memory institutions (viz. museum, libraries, galleries, etc.), reviving the valuable treasure made by generation of people. Digital libraries (DLs) are such powerful contemporary tools for cultural heritage presentation, preservation and archiving. However, DLs power will increase significantly if they use mechanisms for ubiquitous sharing of their e-artefacts and they distribute attractive content in the social networks, reflecting community demands and needs. This paper presents a service for automatic sharing of iconographical artefacts and full collections from the Bulgarian Iconographical Digital Library to selected Facebook communities. In this case the service will be used for widely promotion of knowledge about East-Christian Iconographical Art and Culture, but I could be used not only for this and not only in this domain.

Digitalizing archives and data happens more and more often. There are many obvious advantages of digital data- it won’t change over time, it is much more com-pact compared to any analogue representation and it lasts over time. However there are risks concerning digital archives, too. Each media eventually wears out, which may cause errors when accessing the data. In this paper we propose an approach relying on a combination of virtual hard disks and checksums for data preservation.

In the framework of the Belgian BELSPO AGORA 3D and DIGIT03 programs, we have evaluated 3D digitising technologies with regards to the quality of the acquisition, the capacities and limitations of each technique and also the direct cost of the different 3D digitisation processes. It is on this latest topic that the paper is focused. In order to evaluate the cost of 3D digitisation, we considered the time for the digitisation, cost of the equipment and cost of the staff. Our preliminary results show that the real cost by specimen depends on the amount of specimens to digitise. Techniques that appear to be low-cost can be the most expensive in the framework of massive digitization programs, whilst more expensive equipment can be more efficient in the long term. Therefore low-cost equipment is mainly recommended for occasional digitisation or small series of digitisations.

Hungarian libraries have formed a consortium that led by the National Széchényi Library (NSZL). This consortium is maintaining a project called ELDORADO that provides a new service model and infrastructure environment in digital library field. Our company Cultware is the main system developer partner, focusing on the building of the whole hardware and software architecture and infrastructure of the project. The main scope of the project can be set by some major objectives: Providing digital access for library holdings regardless of their copyright or digitization status. It occurs a large set of on-demand digitisation activities, the registration of digital documents that have digitized already in different libraries in a common single service environment. These activities have coordinated by a library consortium in partnership with all the relevant stakeholders on the related fields. Offering equal and remote access to digital information to all Hungarian spoken people regardless their geographical location is an ultimate goal of the project. Digital access must include a large set of copyrighted materials, orphan works and public domain documents.A major goal (through new collaboration forms with publishers) is to re-publish out-of commerce works in digital format. The project includes collection, preservation and publication activities together in a single service environment.

There has been a huge growth of social network in the recent years. This trend does not only allow us to get connected and share the information in an efficient way, but also reveals some potential beneficial in dealing with several social issues, such as earthquake detection, social spam detection, flu pandemic tracking, media monitoring, etc. In this paper, we propose a new way of utilizing social network. By implementing what is called a Virtual Celebrator Machine (VCM), we are able to let everyone who has connection with this machine in term of social networking be able to share their cultural experience and points of view about certain social events locally or globally. In that way, we provide a way to reinforce the relationship and connection between people virtually, which, we believe, would help to flourish cultural heritage preservation.

Encyclopaedia slavica sanctorum (eslavsanct.net) is designed as a complex heterogenous multimedia product. It is part of the project Encyclopaedia Slavica Sanctorum: Saints and Holy Places in Bulgaria (in electronic and Guthenberg versions). Until 2013, its web-based platform for online management and presentation of structured digital content has been prepared and numerous materials have been input. The platform is developed using the server technologies PHP, MySQL and HTML, JavaScript, CSS on the client side. The search in the e-ESS can be made by different parameters (12, or combinations of parameters), such as saints’ or feasts’ names, type of sainthood, types of texts dedicated to the saints, dates of saints’ commemorations, and several others. Both guests and registered users can search in the e-ESS but the latter have access to much more information including the publications of original sources. The e-platform allows for making statistics of what have been searched and read. The software used for content and access analysis is BI tool QlikView. As an analysis services provider, it is connected to the e-ESS objects repository and tracking services by a preliminary created data warehouse. The data warehouse is updated automatically, achieving real time analytics solution. The paper discusses some of the statistics results of the use of the e-ESS: the activities of the editors, users, and guests, the types of searches, the most often viewed object, such as the date of January 1 and the article on St. Basil the Great which is one of the richest encyclopaedia articles and includes both matadata and original sources published, both from medieval Slavonic manuscripts and popular culture records.

One of the major strategic tasks in Russia’s northwest of the past centuries was the defense of the country’s territories from enemy incursions coming from the West. In order to solve this task, a robust shield in the form of a system of fortresses was created between the 13th and 15th centuries. The system included such fortresses as Koporye, Yam, Korela, Oreshek, and others. In our age, these monuments have become an essential part of Russia’s historic and cultural heritage and an important element of the tourism cluster “The Silver Ring of Russia.” The Centre of Design and Multimedia at St. Petersburg National Research University of Information Technologies, Mechanics and Optics, jointly with the Department of History and the Faculty of Arts at St. Petersburg State University, working under a three-year grant from the Russian Foundation for Humanities Research (#12-01-12041), is implementing a multimedia information system “Ancient Fortresses of Russia’s Northwest”. Historically accurate virtual reconstruction of several fortresses as they existed during certain historic periods, done in such a way as to allow the future creation of virtual tours of these sites, has become the focus of this project’s research. In the present paper, we describe the main phases and results of virtual reconstruction of the best-preserved fortress, Koporye.

The report presents the film 10th century. The South of the Royal Palace in Great Preslav. It consists of two parts – 10th century. The Royal Palace in Great Prelsav. The Square with the Pinnacle and The Ruler’s Lodgings. 3D and virtual reconstructions of an architectural ensemble – part of the Preslav Royal Court unearthed during archaeological researches are used in the film. 3D documentaries have already gained popularity around the world and are well received by both scholars and the public at large. One of the distinguished tourist destinations in Bulgaria is Great Preslav – capital of the mediaeval Bulgarian state and a significant cultural center of the European Southeast in 9th–10th centuries, too. The first part of the film is created with the financial support of America for Bulgaria Foundation and the second – with the funding of Bulgarian National Science Fund at the Ministry of Education, Youth and Science. A team of almost 20 members worked on the film, including computer specialists, professional actors, and translators in the four main European languages – English, German, French and Russian, Trima Sound Recording Studio. In the first part of the 3D film are shown a segment of the Royal Palace, the square with the water pinnacle and the adjacent buildings – an important structural element of the town-planning of the Preslav Court center in the 10th century. In the second part the accent is the southern part of the Royal Palace in Great Preslav, where the personal residence of the Preslav ruler’s dynasty is situated. The work on the virtual reconstruction was done by Virtual Archaeology club at the Mathematical School, Shumen. Due to the efforts of its members it is now clear how the square in front of the southern gate looked like.
