A data model-independent approach to big research data integration
Barralesi Lenzi V., Meghini C., Thanos C.
The paper addresses the data integration problem in the context of the scientific domain. The main characteristics of the big research data that make the traditional approach of data integration unfeasible are presented. Two new emerging practices, i.e. an exploratory approach to data seeking and an empiricist epistemological approach to knowledge creation, are discussed. Based on these considerations, we present a new paradigm of data integration and an application ontology that supports it. The ontology is based on five types of events and every event is extensionally modelled as an input/output operation on the involved data entity. The strong point of the ontology and of the whole approach to data integration is that no assumption is made on the data models in which the databases or the views are expressed. This provides a level of generality that successfully deals with the heterogeneity of the domain.Source: International journal of metadata, semantics and ontologies (Print) 13 (2019): 330–345. doi:10.1504/IJMSO.2019.102680

Big research data integration
Bartalesi Lenzi V., Meghini C., Thanos C.
The paper presents a vision about a new paradigm of data integration in the context of the scientific world, where data integration is instrumental in exploratory studies carried out by research teams. It briefly overviews the technological challenges to be faced in order to successfully carry out the traditional approach to data integration. Then, three important application scenarios are described in terms of their main characteristics that heavily influence the data integration process. The first application scenario is characterized by the need of large enterprises to combine information from a variety of heterogeneous data sets developed autonomously, managed and maintained independently from the others in the enterprises. The second application scenario is characterized by the need of many organizations to combine information from a large number of data sets dynamically created, distributed worldwide and available on the Web. The third application scenario is characterized by the need of scientists and researchers to connect each others research data as new insight is revealed by connections between diverse research data sets. The paper highlights the fact that the characteristics of the second and third application scenarios make unfeasible the traditional approach to data integration, i.e., the design of a global schema and mappings between the local schemata and the global schema. The focus of the paper is on the data integration problem in the context of the third application scenario. A new paradigm of data integration is proposed based on the emerging new empiricist scientific method, i.e., data driven research and the new data seeking paradigm, i.e., data exploration. Finally, a generic scientific application scenario is presented for the purpose of better illustrating the new data integration paradigm, and a concise list of actions that must be performed in order to successfully carry out the new paradigm of big research data integration is described.Source: International Workshop on Information Search, Integration, and Personalization, pp. 23–37, Fukuoka, Japan, 14/05/ 2018, 15/05/2018

White paper on research data service discoverability
Thanos C., Klan F., Kriticos K., Candela L.
This White Paper reports the outcome of a Workshop on "Research Data Service Discoverability" held in the island of Santorini (GR) on 21-22 April 2016 and organized in the context of the EU funded Project "RDA-E3". The Workshop addressed the main technical problems that hamper an efficient and effective discovery of Research Data Services (RDSs) based on appropriate semantic descriptions of their functional and non-functional aspects. In the context of this White Paper, by RDSs are meant those data services that manipulate/transform research datasets for the purpose of gaining insight into complicated issues. In this White Paper, the main concepts involved in the discovery process of RDSs are defined; the RDS discovery process is illustrated; the main technologies that enable the discovery of RDSs are described; and a number of recommendations are formulated for indicating future research directions and making an automatic RDS discovery feasible.Source: Publications 5 (2017). doi:10.3390/publications5010001

Research data reusability: conceptual foundations, barriers and enabling technologies
Thanos C.
High-throughput scientific instruments are generating massive amounts of data. Today, one of the main challenges faced by researchers is to make the best use of the world's growing wealth of data. Data (re)usability is becoming a distinct characteristic of modern scientific practice. By data (re)usability, we mean the ease of using data for legitimate scientific research by one or more communities of research (consumer communities) that is produced by other communities of research (producer communities). Data (re)usability allows the reanalysis of evidence, reproduction and verification of results, minimizing duplication of effort, and building on the work of others. It has four main dimensions: policy, legal, economic and technological. The paper addresses the technological dimension of data reusability. The conceptual foundations of data reuse as well as the barriers that hamper data reuse are presented and discussed. The data publication process is proposed as a bridge between the data author and user and the relevant technologies enabling this process are presented.Source: Publications 5 (2017). doi:10.3390/publications5010002

The Key Role of the DELOS Network of Excellence in Establishing Digital Libraries as a Research Field in Europe
Thanos C., Casarosa V.
It was only in the mid-1990s that Digital Libraries became a research topic in Europe. The European Union was then instrumental in supporting and promoting the subject. One key element of that support was the establishment of the DELOS Network of Excellence. Its central role in the development of digital libraries in the period 1997-2007 in Europe and its contributions areoutlined in this paper.Source: LIBER quarterly 26 (2017): 296–307. doi:10.18352/lq.10165

A vision for open cyber-scholarly infrastructures
Thanos C.
The characteristics of modern science, i.e., data-intensive, multidisciplinary, open, and heavily dependent on Internet technologies, entail the creation of a linked scholarly record that is online and open. Instrumental in making this vision happen is the development of the next generation of Open Cyber-Scholarly Infrastructures (OCIs), i.e., enablers of an open, evolvable, and extensible scholarly ecosystem. The paper delineates the evolving scenario of the modern scholarly record and describes the functionality of future OCIs as well as the radical changes in scholarly practices including new reading, learning, and information-seeking practices enabled by OCIs.Source: Publications 4 (2016). doi:10.3390/publications4020013

Mediation: The technological foundation of modern science
Thanos C.
Modern science is increasingly data-intensive, multidisciplinary, and network-centric. There is an emerging consensus among the members of the academic research community that the practices of this new science paradigm should be congruent with "open science". This entails that the bonanza of research data, the wide availability of algorithms, data tools, and data services produced by the members of the research community must be discoverable, understandable, and usable by overcoming all kinds of heterogeneity and logical inconsistencies. The main concept for coping with the many dimensions of heterogeneity and logical inconsistency is mediation. Mediation is achieved by mediators or brokers. These are software modules that exploit encoded knowledge about certain datasets, data services, and user needs in order to implement an intermediary service. A mediating environment is an environment that provides a core set of intermediary services. Mediation should be a distinct functionality of future research data infrastructures. This paper surveys the different levels of interoperability, i.e., exchangeability, compatibility, and usability, their properties and relationships, mediation concepts, functions, and intermediary services. The current interoperability landscape is also illustrated. Finally, the paper advocates the need for mediating environments to be supported by future research data infrastructures and envisions that one of the most important features of future research data infrastructures will be mediation software.Source: Data science journal 13 (2014): 88–105.

The future of digital scholarship
Thanos C.
This paper advocates that connectivity is the technological foundation of digital scholarship and argues that the characteristics of modern science, i.e. data-centric, multidisciplinary, open, network-centric and heavily dependent on internet technologies entail the creation of a linked, semantically enhanced scholarly record composed of interconnected discipline-specific literature and scientific, social, and humanities data spaces. The changing scenario of the scholarly record is illustrated by describing the principal transformations now being enabled by advanced linking and semantic technologies. The main functionality of a cyberscholarship infrastructure is described, i.e. the ability to effectively and efficiently support a linking environment. (C) 2014 The Authors.

A vision towards Scientific Communication Infrastructures
Castelli D., Manghi P., Thanos C.
The two pillars of the modern scientic communication are Data Centers and Research Digital Libraries, whose technologies and admin staff support researchers at storing, curating, sharing, and discovering the data and the publications they produce. Being realized to maintain and give access to the results of complementary phases of the scientificc research process, such systems are poorly integrated with one another and generally do not rely on the strengths of theother. Today, such a gap hampers achieving the objectives of the modern scientic communication, that is,publishing, interlinking, and discovery of all outcomesof the research process, from the experimental and observational datasets to the final paper. In this work, we envision that instrumental to bridge the gap is the construction of "Scientic Communication Infrastructures". The main goal of these infrastructures is to facilitate interoperability between Data Centers and Research Digital Libraries and to provide services that simplify the implementation of the large variety of modern scientific communication patterns.Source: International journal on digital libraries (Print) 13 (2013): 165–169. doi:10.1007/s00799-013-0106-7

A vision for global research data infrastructures
Thanos C.
New high-throughput scientific instruments, telescopes, satellites, accelerators, supercomputers, sensor networks, and running simulations are generating massive amounts of data. In order to be able to exploit these huge volumes of data, a new type of e-infrastructure, the Global Research Data Infrastructure (GRDI), must be developed for harnessing the accumulating data and knowledge produced by the communities of research. This paper identifies the main challenges faced by the future GRDIs, defines a conceptual framework for GRDIs based on the ecosystem metaphor, describes a core set of functionality that these GRDIs must provide, and gives a set of recommendations for building the future GRDIs.Source: Data science journal 12 (2013): 71–90. doi:10.2481/dsj.12-043

RDA EUROPE - First year report on Roadmap to achieve full interoperability of EU-US data infrastructures
Wittenburg P., Stehouwer H., Baxter R., Karayannis F., Castelli D., Thanos C., Genova F., Laaksonen L.
In this report we examine the state of current data infrastructures and repositories and conclude that the European landscape is very heterogeneous and that there is no reason to assume that this will change soon. There are stakeholders at European level, at national level and at research organisation level, some organized along scientific dsciplines, some cross-disciplinary. There are an increasing number of commercial services for which the question of trust will be very important for researchers. Improving interoperability and data sharig requires that we find ways of harmonisation which have the potential to overcome the barriers introduced by this diversity. Our conclusions on the state of the current RDA roadmap lead us to five recommendations.Source: Project report, RDA Europe, Deliverable D2.3, 2013

Comunicazione scientifica: la nuova frontiera
Castelli D., Manghi P., Thanos C.
The new Science paradigm, based on data-intensive computing, leads to a new data-centric way of carrying out research activities. The pioneer vision of Jim Gray on the need of unifying all scientific data with the related literature is emerging as a reality and revolutionizing scientific publishing as a whole. In fact, data is becoming a first class citizen of modern scientific communication. This new role of data in the scientific communication is made feasible by the definition of new formal publication models, where a publication is intended as a set of "information units", including text, datasets, images, videos, sound recordings, mathematical models, workflows, presentation materials, and software packages meaningfully connected by relationships. The two pillars of modern scientific communication are discipline-specific Data Centers and Research Digital Libraries. Being realized to implement complementary phases of scientific research and publication process, these are poorly integrated with one another. We envision that research efforts must be undertaken in order to bridge the gap between published ideas and the underlying data, and make the relationship between data and publication more dynamic.Source: Digitalia (Testo stamp.) 2 (2012): 29–39.

DL.org - Digital library technology and methodology cook book
Athanasopoulos G., Candela L., Castelli D., El Raheb K., Innocenti P., Ioannidis Y., Katifori A., Nika A., Ross S., Tani A., Thanos C., Toli E., Vullo G.
The demand for powerful and rich Digital Libraries able to support a large variety of interdisciplinary activities as well as the data deluge the information society is nowadays confronted with have increased the need for 'building by re-use' and 'sharing'. Interoperability at a technical, semantic and organisational level is a central issue to satisfy these needs. Despite its importance, and the many attempts to resolve this problem in the past, existing solutions are still very limited. The main reasons for this slow progress are lack of any systematic approach for addressing the issue and scarce knowledge of the adopted solutions. Too often these remain confined to the systems they have been designed for. In order to overcome this gap, DL.org promotes the production of this document with the goal to collect and describe a portfolio of best practices and pattern solutions to common issues faced when developing large-scale interoperable Digital Library systems. This document represents the final version of the Digital Library Technology and Methodology CookbookSource: Project report, DL.org, Deliverable D3.4, 2011
