Report on the EuDML external cooperation model

One of the main tasks of the European Digital Mathematics Library project was to define a cooperation model with a variety of stakeholders that would allow building a reliable and durable global reference library, aiming to be eventually exhaustive. In this paper we present the EuDML external cooperation model and the business plan as the basis for its sustainability and further development.Comment: Small edits for publication.

Escaping the Trap of too Precise Topic Queries

At the very center of digital mathematics libraries lie controlled vocabularies which qualify the {\it topic} of the documents. These topics are used when submitting a document to a digital mathematics library and to perform searches in a library. The latter are refined by the use of these topics as they allow a precise classification of the mathematics area this document addresses. However, there is a major risk that users employ too precise topics to specify their queries: they may be employing a topic that is only "close-by" but missing to match the right resource. We call this the {\it topic trap}. Indeed, since 2009, this issue has appeared frequently on the i2geo.net platform. Other mathematics portals experience the same phenomenon. An approach to solve this issue is to introduce tolerance in the way queries are understood by the user. In particular, the approach of including fuzzy matches but this introduces noise which may prevent the user of understanding the function of the search engine. In this paper, we propose a way to escape the topic trap by employing the navigation between related topics and the count of search results for each topic. This supports the user in that search for close-by topics is a click away from a previous search. This approach was realized with the i2geo search engine and is described in detail where the relation of being {\it related} is computed by employing textual analysis of the definitions of the concepts fetched from the Wikipedia encyclopedia.Comment: 12 pages, Conference on Intelligent Computer Mathematics 2013 Bath, U

Challenges to the Support of Bulgarian Open Institutional Repositories

Open access academic archives are the proper instrument to make visible the majority of the works done during the years and to propagate the results of already paid research activities, thus raising their value. This is the way to achieve an improved management of intellectual assets of the whole university and research community. This paper examines the indicators of the success as well as the challenges in the support of Bulgarian institutional repositories. The findings are based on a comparative case study of the six repositories in research institutes and universities and the local repository of the Department of Informatics at New Bulgarian University

LIBER 41st Annual Conference : Mobilising the Knowledge Economy for Europe

Conference Programme. 27–30 June 2012, Tart

A Knowledge Base of Mathematical Results

International audienceThe basic unit of information of use by researchers in theoretical fields are the mathematical results. We aim to build a knowledge base of these results, using information extraction techniques on scholarly documents. We present an algorithm which extracts mathematical results and references to mathematical results from scientific papers, using their PDF or LATEX sources. We analyse the results of our algorithm on the whole arXiv database of scientific papers and explore the resulting graph of mathematical results, which contains more than 6 million results and 4.5 million edges. We present attempts to link theorems of different papers using a TFIDF vectorizer or an autoencoder

ERAWATCH Country Reports 2013: Bulgaria

The Analytical Country Reports analyse and assess in a structured manner the evolution of the national policy research and innovation in the perspective of the wider EU strategy and goals, with a particular focus on the performance of the national research and innovation (R&I) system, their broader policy mix and governance. The 2013 edition of the Country Reports highlight national policy and system developments occurring since late 2012 and assess, through dedicated sections: -National progress in addressing Research and Innovation system challenges; -National progress in addressing the 5 ERA priorities; -The progress at Member State level towards achieving the Innovation Union; -The status and relevant features of Regional and/or National Research and Innovation Strategies on Smart Specialisation (RIS3); -As far relevant, country Specific Research and Innovation (R&I) Recommendations. Detailed annexes in tabular form provide access to country information in a concise and synthetic manner. The reports were originally produced in December 2013, focusing on policy developments occurring over the preceding twelve months.JRC.J.2-Knowledge for Growt

Products and Services

Today’s global economy offers more opportunities, but is also more complex and competitive than ever before. This fact leads to a wide range of research activity in different fields of interest, especially in the so-called high-tech sectors. This book is a result of widespread research and development activity from many researchers worldwide, covering the aspects of development activities in general, as well as various aspects of the practical application of knowledge
