15.15 – 17.15. Th. Risse. Approaches for large scale digital library infrastructures (2 h. // Vol. 1, p. ).

Abstract. Current plans for next generation DL architectures are aiming for a transition from the DL as an integrated, centrally controlled system to a large scale federation of DL services and information collections. The transition is driven by DL "market" needs and inspired by new technology trends that promise to solve at least part of these market needs. With the uptake of DLs in a wider community there is a need for better and adaptive tailoring of the content and service offer of a DL to the needs of the respective community as well as to the current service and content offer. Furthermore, there is a need for more systematic exploitation of existing resources like information collections, metadata collections, and services for making DLs more cost-effective as well as a need for opening up of DL technology to a wider. New technologies and paradigms like Peer-to-Peer networking and Service-oriented Architectures (SOA) suggest digital libraries that operate on more demand-oriented and flexible distributed or decentralized infrastructures. The tutorial aims to introduce to the audience various central aspects of bringing digital libraries to large scale infrastructures by discussing core ideas and related architectural options. Furthermore, it introduces the underlying technologies as a foundation for the understanding of the concrete solutions. The main part of the tutorial revolves around the following selected DL topics:

  • Content and Metadata Management
  • Navigation through the information space

For each of the topics the key challenges are discussed together with possible solutions for the challenges and the lessons learned in implementing these solutions. The solutions are illustrated with concrete examples and small system demos from the BRICKS project.

Abstract. The Socionet system is the first Russian professional social network for education and research areas. It is also a platform to build e-Social Sciences infrastructure at national level. Socionet information resources are integrated into national Common Scientific Information Space of Russian Academy of Sciences and have relations with international e-Science online infrastructure. The Socionet system used some ideas, methods and tools of RePEc (Research Papers in Economics) project and OAI (Open Archives Initiative). An added value of the Socionet is advanced architecture of relations among different types of information objects, which allows better navigation, research performance indexes, scientometric analysis and metadata quality indicators. The proposed article describes general features of the Socionet and its methods of information resources integration. The article also discusses possible implementations of scientometrics based on Socionet statistics and a problem of metadata quality measurements.

Abstract. The interrelationship between the objects of astronomical catalogs in the different ranges of electromagnetic spectrum and their association into the real astrophysical source has obvious scientific interest. Astronomical community actively uses the Internet for the access to the scientific information, but the heterogeneity of data and their constantly growing volumes are the certain difficulty. The gathering of information even about one celestial object is time-taking work because of a large quantity of resources, data access, formats of the obtained results and formats of input data of the program applications, used for further analysis. The community activity on the creation of the architecture of information interaction, standards, format specifications, data models and services, which increase the efficiency of work with the data, coordinates International Virtual Observatory Alliance (IVOA). Within the framework of this activity are created systems, which make it possible to realize the distributed computing and data access. We decided to analyze the usage of existing software tools for investigation the radio sources list. .

Abstract. The central question of image navigation system construction is to build the projection of the collection into the two-dimensional space of navigation. The kernel of the method proposed is to build the projection in two steps. At the first step the hierarchical system of clusters is constructed. At the second step the initial space of image descriptions is projected into two-dimensional navigation space.

A survey of methods used for navigation system construction is given. The results of experimental analysis are present. The proposed method is compared to known methods. The results of this work allow to draw a conclusion of ability to successfully apply the method developed.

Abstract. It is a common way in CBIR to process different image features independently to estimate image similarity. Color and texture are common features which are used for searching in natural images. This paper proposes the hypothesis that it is possible to mark out optimal weights for fusing color and texture-based estimations in accordance with query image features. Linear combination of color and texture metrics is considered as a mixed-metrics. Clusters of images with common features and optimal weights for them are presented based on experimental results. The results of the paper can be used to determine the best weights for particular query and thus improve image retrieval.

Abstract. The paper is continuing the investigation line of application of type refinement for heterogeneous ontological descriptions of a subject area. Most typical task of ontological specification manipulations are considered. They are: verification of ontological definition for internal consistency, mapping and integration of ontological contexts, ontology development, information contextualization and personalization, conceptual model development on the base of ontology, querying and messaging in terms of ontology. The claim of the paper is to show ability of application of refinement relation in tasks that are usual in ontology modeling.

Abstract. In the paper we consider ontological characteristics of such concepts as roles and show their distinctions from type concepts. We argue that the difference between types and roles is necessary to account in ontological and linguistic resources intended for automatic text processing if the automatic inference procedure is planned.

We show that information about concepts and entities obtained from text definitions often leads to incorrect descriptions of type-role relations, and it is necessary to make special efforts to describe this information appropriate for the logical inference.

We discuss possible means for description of the type-role relations used in the Thesaurus of Russian Language RuThes.

Abstract. Our article covers various terms and development technologies for Scalable Vector Graphic using in digital libraries of handwritten historical documents.

Full-text nature of the initial information and natural hierarchical structure of the documents define XML-technology as a choice and a basis for texts storing. But, if we use XML for allocation of logic elements in the texts of our library, it looks logically to apply the same technology to other purposes - for example, for building of queries to a collection of the documents or for visualization of the information at different stages of our work with the texts.

In this article, the basic attention is given to four variants of SVG using. We talk about making dependencies between XML-markup and images of initial documents. We describe special vector fonts definition for adequate representing of original texts. We demonstrate different forms of visualization as results of analytical queries to a collection of the documents. We also offer to use SVG-based editor for graphs models creating.

The considered approach is used in practice in development of special toolkit for information system "Istochnik" ("Source") intended for network community of the researchers.

Abstract. The basic facilities and features of most popular DSpace and EPrints open source systems for construction of scientific digital libraries are considered in the work. And also experience in creation of multilingual digital libraries on these basis is described. Comparative analysis of DSpace 1.4.1 and EPrints 3.1 is presented. Special attention is given to problems of localization, external formats compatibility and usability.

16.00 – 16.20. O. Bartunov, T. Sigaev. Specialized data types for digital libraries (20 m. // Vol. 2, p. 90-96).

Abstract. Complex modern informational systems require specialized data types, optimized for fast access and tasks of informational retrieval. Rapid changes in patterns of access to information require extensibility of database engine to allow experts in the data domain to develop custom data type, optimized for data domain. We describe several data types, developed for the open-source ORDBMS PostgreSQL, which facilitate operations with sets, hierarchical data, semistructured data and full-text search. Also, we describe PostgreSQL infrastructure for developing extensions.

16.20 – 16.40. C. Becker, S. Strodl, R. Neumayer, A. Rauber, E. Nicchiarelli, M. Kaiser. Long-Term Preservation of Electronic Theses and Dissertations: A Case Study in Preservation (20 m. // Vol. 2, p. 97-103).

Abstract. An increasing number of institutions throughout the world face legal obligations to collect and preserve digital objects over years. A range of tools exist today to support the variety of preservation strategies such as migration or emulation. Yet, different preservation requirements across institutions and settings make the decision on which solution to implement very difficult. The Austrian National Library will have to preserve electronic theses and dissertations provided in PDF. It is thus investigating potential preservation solutions. The preservation planning approach taken in the PLANETS project is used to evaluate various alternatives with respect to specific requirements. It provides an approach to make informed and accountable decisions on which solution to implement in order to preserve digital objects for a given purpose. We analyse the performance of various preservation strategies with respect to the specified requirements for the preservation of master's theses and dissertations and present the results.

9.30 – 10.00. D. Briukhov, L. Kalinichenko, D. Martynov. Source Registration and Query Rewriting Applying LAV/GLAV Techniques in a Typed Subject Mediator (30 m. // Vol. 1, p. 253-262).

Abstract. New methods and tools for application development in collaborative scientific enterprises (like Virtual Observatories (VO)) over multiple distributed sources of data and programs are required. In this paper we focus on results of research and experimental work oriented on problem-driven subject mediation emphasizing aspects of LAV/GLAV information sources integration in the mediator. The approach considered has the following distinguishing features: typed, object canonical model is used instead of usually applied relational one; a technique of refining mapping of source information models into extensible canonical one is provided; registration in a mediator of a relevant source is done so that a mediator type should be provably refined by a relevant source type or by a composition of such types (the conflict resolving functions are to be specified, if required); rewriting of non-recursive logical programs containing strongly typed rules is applied. These features provide methodological context for the current paper that is focused on description of the role the LAV/GLAV approach plays in the mediator. Using astronomical example taken from the Russian VO context, we show the technique of information source registration at the mediator and query rewriting technique in a typed specification environment applying LAV/GLAV approach.

10.00 – 10.30. A. Zhuchkov, A. Kravchenko, N. Tverdokhlebov. Service-oriented GRID-approach to maintain data spaces of virtual organizations (30 m. // Vol. 1, p. 263-272).

Abstract. This article covers the adaptation of some facilities of Grid-technology in order to form the Data Spaces support platform. It shows also an example of the constructing of a high-level service which operates in the subject-oriented Data Space of a medical Virtual Organization.

11.15 – 11.35. A. Fedotov, V. Barakhnin, A. Guskov, J. Leonova. Developing information system for scientific society based on the integration of heterogeneous heterogenius heterogenius collections of resources (20 m. // Vol. 2, p. 111-117).

Abstract. In this paper the technology for information system ``Organizations and employees of SB RAS directory'' creation is described. This technology based on the principle of decentralized information storage with an integrated resource catalogue. Such approach provides the possibility of automatic actualization of information and system's interoperability - the possibility of heterogeneous resource integration within the system and between external systems.

11.35 – 11.55. O. Klimenko, V. Philippov, M. Philippova. Digital Library of Mathematicle Resources MathTree (20 m. // Vol. 2, p. 118-121).

Abstract. MathTree library represents a set of integrated links to Internet resources. The links are stored with some metadata in a tree catalogue where different branches correspond to various aspects of mathematics. Moving along the branches allows one to get information related to a specific aspect of mathematics: research laboratories, scientific schools, departments, specialists in the given field, theses and other digital resources, links to magazines where articles on the subject are published, and conferences on related topics.

11.55 – 12.15. I. Smirnov, O. Pugachev, A. Lobanov, A. Alimov, E. Voronina. Digital marine animals collections of the Zoological Institute RAS and their metadata (20 m. // Vol. 2, p. 122-127).

Abstract. One of the ways to make easier and accelerate the search of necessary information on the Internet is the integration and standardization of databases on the biodiversity and their metadata. Presently in the information retrieval systems some standards of data input, description and presentation are being used, among them Darwin Core, RDF, Dublin Core Metadata Elements etc.

12.15 – 12.35. S. Chernov, E. Minack, P. Serdyukov. Converting Desktop into a Personal Activity Dataset (20 m. // Vol. 1, p. 280-283).

Abstract. The current experiments on personalization in information retrieval are limited to the available collections of the real world data. While a number of publications exploited user interaction with Desktop, often these experiments are neither repeatable nor comparable. In this paper we elaborate on the need for logging the Desktop activity data and creating a common collection for Desktop search evaluation. We describe the design of such a dataset and necessary logging tools. We also outline the current state of our Personal Activity Track initiative towards creation of the Desktop search dataset. While this effort is currently targeting English-speaking users, it is also applicable to Russian and other languages.

Access Control and Exceptions

13.35 (Top floor ) Russian Information Retrieval Evaluation Seminar.

13.35 – 14.05. A. Berztiss, B. Thalheim. Exceptions in Information Systems (30 m. // Vol. 1, p. 284-295).

Abstract. The concept of exception has been defined in diverse ways. We relate exceptions to computational transactions and to control constructs. Our view of a transaction is very broad, and we consider transactional exceptions to be instances of undefined function values. By giving different interpretations to ``undefined'' we arrive at a classification of transactional exceptions. Our primary interest is in information systems, i.e., in database transactions, and in processes that consist of such transactions. In the database context we show that liberal treatment of exceptions is simpler than total quality management for consistency based on a set of constraints. We refer to control operations that link transactions into processes as actions. Actions tend to be time-related, and time Petri nets provide actions with semantics. The time Petri net representation indicates where exceptions can arise. We also consider high-level monitors for the detection of exceptions. Although our emphasis is on detection of exceptions, their handling is also discussed.

14.05 – 14.35. O. Zhizhimov, A. Fedotov. Models of management of access to the distributed information resources (30 m. // Vol. 1, p. 296-299).

Abstract. On the basis of the analysis of typical scenarios of work of information servers (WWW, FTP, Z39.50, etc.) problems which should dare at the organization of the monitoring system of access to the distributed information resources are formulated. Possibilities of technology LDAP as similar system most suitable to construction are considered. Within the limits of this technology by the access, differing degree of integration of functions of information servers three models of management are discussed with technology LDAP.

14.35 – 14.55. E. Ivashko. The defensive system against unauthorized documents-copying of the digital libraries development (20 m. // Vol. 1, p. 300-306).

Abstract. In this article we consider problems of applying statistical anomaly detection algorithm to preserve digital libraries from unauthorized full-scale documents copying. We propose modernized intrusion detection technique based on Markov chains for creating classifiers and patterns of normal behavior.
