Semantic representation and enrichment of information retrieval experimental data

Posté le par

Authors : Gianmaria Silvello, Georgeta Bordea, Nicola Ferro, Paul Buitelaar, Toine Bogers

Experimental evaluation carried out in international large-scale campaigns is a fundamental pillar of the scientific and technological advancement of information retrieval (IR) systems.

Such evaluation activities produce a large quantity of scientific and experimental data, which are the foundation for all the subsequent scientific production and development of new systems.

In this work, we discuss how to semantically annotate and interlink this data, with the goal of enhancing their interpretation, sharing, and reuse. We discuss the underlying evaluation workflow and propose a resource description framework model for those workflow parts.

We use expertise retrieval as a case study to demonstrate the benefits of our semantic representation approach. We employ this model as a means for exposing experimental data as linked open data (LOD) on the Web and as a basis for enriching and automatically connecting this data with expertise topics and expert profiles.

In this context, a topic-centric approach for expert search is proposed, addressing the extraction of expertise topics, their semantic grounding with the LOD cloud, and their connection to IR experimental data.

Several methods for expert profiling and expert finding are analysed and evaluated. Our results show that it is possible to construct expert profiles starting from automatically extracted expertise topics and that topic-centric approaches outperform state-of-the-art language modelling approaches for expert finding.

Penser les relations médiatiques du livre et de l’hypertexte à partir de 253 de Geoff Ryman et Luminous Airplanes de Paul La Farge

Posté le par

Auteur/Author : Gaëlle Debeaux

À travers deux exemples d’œuvres romanesques contemporaines à cheval sur deux médias, cet article vise à analyser les processus de remédiatisation et de transmédiatisation qui impliquent le développement narratif d’un récit à la fois dans un livre et dans un hypertexte.

Il s’agit de chercher à comprendre comment on peut transposer la logique hypertextuelle en logique livresque, et comment on raconte des histoires sur ces deux dispositifs, comment une même histoire peut être développée d’un dispositif à l’autre.

In the era of computation and data-driven research, traditional methods of disseminating research are no longer fit-for-purpose. New approaches for disseminating data, methods and results are required to maximize knowledge discovery.

The “long tail” of small, unstructured datasets is well catered for by a number of general-purpose repositories, but there has been less support for “big data”. Outlined here are our experiences in attempting to tackle the gaps in publishing large-scale, computationally intensive research.

GigaScience is an open-access, open-data journal aiming to revolutionize large-scale biological data dissemination, organization and re-use. Through use of the data handling infrastructure of the genomics centre BGI, GigaScience links standard manuscript publication with an integrated database (GigaDB) that hosts all associated data, and provides additional data analysis tools and computing resources.

Furthermore, the supporting workflows and methods are also integrated to make published articles more transparent and open. GigaDB has released many new and previously unpublished datasets and data types, including as urgently needed data to tackle infectious disease outbreaks, cancer and the growing food crisis.

Other “executable” research objects, such as workflows, virtual machines and software from several GigaScience articles have been archived and shared in reproducible, transparent and usable formats.

With data citation producing evidence of, and credit for, its use in the wider research community, GigaScience demonstrates a move towards more executable publications. Here data analyses can be reproduced and built upon by users without coding backgrounds or heavy computational infrastructure in a more democratized manner.

Advancing research data publishing practices for the social sciences: from archive activity to empowering researchers

Posté le par

Authors : Veerle Van den Eynden, Louise Corti

Sharing and publishing social science research data have a long history in the UK, through long-standing agreements with government agencies for sharing survey data and the data policy, infrastructure, and data services supported by the Economic and Social Research Council.

The UK Data Service and its predecessors developed data management, documentation, and publishing procedures and protocols that stand today as robust templates for data publishing.

As the ESRC research data policy requires grant holders to submit their research data to the UK Data Service after a grant ends, setting standards and promoting them has been essential in raising the quality of the resulting research data being published. In the past, received data were all processed, documented, and published for reuse in-house.

Recent investments have focused on guiding and training researchers in good data management practices and skills for creating shareable data, as well as a self-publishing repository system, ReShare. ReShare also receives data sets described in published data papers and achieves scientific quality assurance through peer review of submitted data sets before publication.

Social science data are reused for research, to inform policy, in teaching and for methods learning. Over a 10 years period, responsive developments in system workflows, access control options, persistent identifiers, templates, and checks, together with targeted guidance for researchers, have helped raise the standard of self-publishing social science data.

Lessons learned and developments in shifting publishing social science data from an archivist responsibility to a researcher process are showcased, as inspiration for institutions setting up a data repository.

Analyse sociologique et économique du financement participatif. Ressorts et critiques dans le cas du journalisme (2010-2015)

Posté le par

Auteur/Author : Guillaume Goasdoué

Le système du financement participatif met en relation des contributeurs individuels et des médias qui cherchent des fonds pour quatre raisons principales : le sauvetage, la diversification, la création, les projets ponctuels.

Comment le capital (symbolique, social) accumulé par les porteurs de projet favorise-t-il l’ampleur et l’issue des collectes ? De quelles manières la dimension sociale du mécanisme est-elle exploitée par ce type de procédé de collecte de fonds ?

D’abord, nous répondrons à ces questions en commençant par discuter des limites de la littérature internationale. Ensuite, nous présenterons nos données pour le secteur de l’information, puis nous traiterons plus spécifiquement des ressorts sociaux du phénomène.

Enfin, nous finirons par les aspects liés au travail de recherche de visibilité. Seront ainsi critiquées quelques idées reçues, puis exposées diverses formes d’inégalités entre les médias qui recourent à ce système.

TrueReview: A Platform for Post-Publication Peer Review

Posté le par

Authors : Luca de Alfaro, Marco Faella

In post-publication peer review, scientific contributions are first published in open-access forums, such as arXiv or other digital libraries, and are subsequently reviewed and possibly ranked and/or evaluated.

Compared to the classical process of scientific publishing, in which review precedes publication, post-publication peer review leads to faster dissemination of ideas, and publicly-available reviews. The chief concern in post-publication reviewing consists in eliciting high-quality, insightful reviews from participants.

We describe the mathematical foundations and structure of TrueReview, an open-source tool we propose to build in support of post-publication review.

In TrueReview, the motivation to review is provided via an incentive system that promotes reviews and evaluations that are both truthful (they turn out to be correct in the long run) and informative (they provide significant new information).

TrueReview organizes papers in venues, allowing different scientific communities to set their own submission and review policies. These venues can be manually set-up, or they can correspond to categories in well-known repositories such as arXiv.

The review incentives can be used to form a reviewer ranking that can be prominently displayed alongside papers in the various disciplines, thus offering a concrete benefit to reviewers. The paper evaluations, in turn, reward the authors of the most significant papers, both via an explicit paper ranking, and via increased visibility in search.

Understanding the Impact of Early Citers on Long-Term Scientific Impact

This paper explores an interesting new dimension to the challenging problem of predicting long-term scientific impact (LTSI) usually measured by the number of citations accumulated by a paper in the long-term.

It is well known that early citations (within 1-2 years after publication) acquired by a paper positively affects its LTSI. However, there is no work that investigates if the set of authors who bring in these early citations to a paper also affect its LTSI.

In this paper, we demonstrate for the first time, the impact of these authors whom we call early citers (EC) on the LTSI of a paper. Note that this study of the complex dynamics of EC introduces a brand new paradigm in citation behavior analysis.

Using a massive computer science bibliographic dataset we identify two distinct categories of EC – we call those authors who have high overall publication/citation count in the dataset as influential and the rest of the authors as non-influential.

We investigate three characteristic properties of EC and present an extensive analysis of how each category correlates with LTSI in terms of these properties. In contrast to popular perception, we find that influential EC negatively affects LTSI possibly owing to attention stealing.

To motivate this, we present several representative examples from the dataset. A closer inspection of the collaboration network reveals that this stealing effect is more profound if an EC is nearer to the authors of the paper being investigated.

As an intuitive use case, we show that incorporating EC properties in the state-of-the-art supervised citation prediction models leads to high performance margins.

At the closing, we present an online portal to visualize EC statistics along with the prediction results for a given query paper.
