Background Open Science Graphs (OSGs) are scientific knowledge graphs representing different entities of the research lifecycle (e.g. projects, people, research outcomes, institutions) and the relationships among them. They present a contextualized view of current research that supports discovery, re-use, reproducibility, monitoring, transparency a...

Classifying scientific publications according to Field-of-Science taxonomies is of crucial importance, powering a wealth of relevant applications including Search Engines, Tools for Scientific Literature, Recommendation Systems, and Science Monitoring. Furthermore, it allows funders, publishers, scholars, companies, and other stakeholders to organi...

Lack of reproducibility of research results has become a major theme in recent years. As we emerge from the COVID-19 pandemic, economic pressures and exposed consequences of lack of societal trust in science make addressing reproducibility of urgent importance. TIER2 is a new international project funded by the European Commission under their Horiz...

In recent years, assessing the performance of researchers has become a burden due to the extensive volume of the existing research output. As a result, evaluators often end up relying heavily on a selection of performance indicators like the h-index. However, over-reliance on such indicators may result in reinforcing dubious research practices, whi...

The growth rate of the number of scientific publications is constantly increasing, creating important challenges in the identification of valuable research and in various scholarly data management applications, in general. In this context, measures which can effectively quantify the scientific impact could be invaluable. In this work, we present BI...

Despite the hype, the effective implementation of Open Science is hindered by several cultural and technical barriers. Researchers embraced digital science, use “digital laboratories” (e.g. research infrastructures, thematic services) to conduct their research and publish research data, but practices and tools are still far from achieving the expec...

Open Access and Open Scholarship have revolutionized the way scholarly artefacts are evaluated and published, while the introduction of new technologies and media in scientific workflows has changed the "how" and to "whom" science is communicated, and how stakeholders interact with the scientific community and the broader public. The EU funded proj...

Authors of scientific publications and books use images to present a wide spectrum of information. Despite the richness of the visual content of scientific publications the figures are usually not taken into consideration in the context of text mining methodologies towards the automatic indexing and retrieval of scientific corpora. In this work, we...

The Information Inference Framework presented in this paper provides a general-purpose suite of tools enabling the definition and execution of flexible and reliable data processing workflows whose nodes offer application-specific processing capabilities. The IIF is designed for the purpose of processing big data, and it is implemented on top of Apa...

Text visualization is a rather important task related to scientific corpora, since it provides a way of representing these corpora in terms of content, leading to reinforcement of human cognition compared to abstract and unstructured text. In this paper, we focus on visualizing funding-specific scientific corpora in a supervised context and discove...

A method for supervised classification and visualization of collections of scientific publications is presented. By integrating a text classification module, which leads to class probability estimation, along with a dimensionality reduction technique, which represents each class in the 2-D space, any collection of unlabelled documents can be visual...

The aim of the ESPAS e-Infrastructure is to facilitate access to data from the near-Earth space environment enabling exploitation of multi-instrument, multi-point science data for analysis, model building, data assimilation into models, model-observation comparison, space environment nowcast and forecast, to name just a few. The ESPAS project, cur...

OpenAIRE is the European Union initiative for an Open Access Infrastructure for Research in support of open scholarly communication and access to the research output of European funded projects and open access content from a network of institutional and disciplinary repositories. This article outlines the curation activities conducted in the OpenAI...

A supervised approach to visualization of collections of scientific documents is presented. We have implemented a text classification module, which leads to class probability estimations, along with a dimensionality reduction technique which represents each class in the 2-D space. Integrating those two procedures, any collection of unlabelled docum...

OpenAIRE and OpenAIREplus (Open Access Infrastructure for Research in Europe) are EC funded projects (Dec 2009 - May 2014) whose goals are to realize, enhance, and operate the Open Access European scholarly communication data infrastructure. This paper describes the high-level architecture and functionalities of that infrastructure, including servi...

PAROS is a generic system under design whose goal is to offer personalization, recommendation, and other adaptation services to information providing systems. In its heart lies a rich user model able to capture several diverse aspects of user behavior, interests, preferences, and other attitudes. The user model is instantiated with profiles of user...

With the popularity of social media sites, digital content is increasingly stored and managed online. At the same time, the desktop and local storage continues to provide a personal environment in which users perform their daily tasks. Thus, to accomplish their tasks, users need to continuously switch between local and remote resources and applicat...

Digital Library (DL) interoperability, as it is being reported in the DL.org Digital Library Reference Model, is intimately related to function interoperability. A prerequisite for the later is an appropriate function description, publication and discovery mechanisms. The importance of a framework which accommodates the specification of key DL func...

Scholarly research involves a systematic study of information sources in order to establish facts and reach new conclusions. It encompasses survey, analysis, evaluation, and creation as distinct phases that are performed iteratively and often in parallel by accessing a range of local and remote resources. Throughout these activities scholars create...

Digital Library (DL) interoperability requires addressing a variety of issues associated with functionality. We report on the analysis and solutions identified by the Functionality Working Group of the DL.org project during its deliberations on DL interoperability. Ultimately, we hope that work based on our perspective will lead to improved archite...

The constant interaction of users with different Digital Libraries (DLs) and the subsequent scattering of user information across them raise the need not only for Digital Library interoperability but also for cross-Digital Library personalization. The latter calls for sharing and combining of user-information across different DL systems so that a D...

The OpenAIRE project aims at supporting the diffusion and adoption of the European Commission Open Access mandates among researchers in Europe. It will deliver an organizational/technological infrastructure "supporting mechanisms for the identification, deposition, access, and monitoring of FP7 and ERC funded articles". The organizational infrastru...

At the third workshop on Usage Statistics which took place in Berlin om 29-30 March 2010 a group of experts came together to describe a vision on the future of usage statistics. This resulted in the briefing paper which can be found below. In this paper they make a cause for collecting and exchanging usage statistics as this can provide valuable i...

Due to the wide diffusion of digital repositories, organizations responsible for large research communities, such as national or project consortia, research institutions, foundations, are increasingly tempted into setting up so-called repository infrastructure systems (e.g., OAIster (http://www.oaister.org), BASE (http://www.base-search.net), DAREn...
