Contextualization of topics - browsing through terms, authors, journals and cluster allocations
This paper builds on an innovative Information Retrieval tool, Ariadne. The
tool has been developed as an interactive network visualization and browsing
tool for large-scale bibliographic databases. It basically allows to gain
insights into a topic by contextualizing a search query (Koopman et al., 2015).
In this paper, we apply the Ariadne tool to a far smaller dataset of 111,616
documents in astronomy and astrophysics. Labeled as the Berlin dataset, this
data have been used by several research teams to apply and later compare
different clustering algorithms. The quest for this team effort is how to
delineate topics. This paper contributes to this challenge in two different
ways. First, we produce one of the different cluster solution and second, we
use Ariadne (the method behind it, and the interface - called LittleAriadne) to
display cluster solutions of the different group members. By providing a tool
that allows the visual inspection of the similarity of article clusters
produced by different algorithms, we present a complementary approach to other
possible means of comparison. More particular, we discuss how we can - with
LittleAriadne - browse through the network of topical terms, authors, journals
and cluster solutions in the Berlin dataset and compare cluster solutions as
well as see their context.Comment: proceedings of the ISSI 2015 conference (accepted

Full Report: Use and Users of Digital Resources: A Focus on Undergraduate Education in the Humanities and Social Sciences
A "build it and they will come" approach to many university digitization initiatives has precluded systematic investigations of the demand for these resources. Those who fund and develop digital resources have identified the general lack of knowledge about the level and quality of their use in educational settings as pressing concerns. This full report describes our research and the complete results of a large 2-year study. The purpose of our research was (1) to map the universe of digital resources available to a subset of undergraduate educators in the humanities and social sciences, and (2) to investigate how and if available digital resources are actually being used in undergraduate teaching environments. We employed multiple methods, including surveys and focus groups. Our definition of digital resources was intentionally broad and included rich media objects (e.g., maps, video, images, etc.) as well as text
Field Trials of Health Interventions: A Toolbox
Before new interventions can be used in disease control programmes, it is essential that they are carefully evaluated in âfield trialsâ, which may be complex and expensive undertakings. Descriptions of the detailed procedures and methods used in trials that have been conducted in the past have generally not been published. As a consequence, those planning such trials have few guidelines available and little access to previously accumulated knowledge. In this book the practical issues of trial design and conduct are discussed fully and in sufficient detail for the text to be used as a âtoolboxâ by field investigators. The toolbox has now been extensively tested through use of the first two editions and this third edition is a comprehensive revision, incorporating the many developments that have taken place with respect to trials since 1996 and involving more than 30 contributors. Most of the chapters have been extensively revised and 7 new chapters have been added
Managing Distributed Cloud Applications and Infrastructure
The emergence of the Internet of Things (IoT), combined with greater heterogeneity not only online in cloud computing architectures but across the cloud-to-edge continuum, is introducing new challenges for managing applications and infrastructure across this continuum. The scale and complexity is simply so complex that it is no longer realistic for IT teams to manually foresee the potential issues and manage the dynamism and dependencies across an increasing inter-dependent chain of service provision. This Open Access Pivot explores these challenges and offers a solution for the intelligent and reliable management of physical infrastructure and the optimal placement of applications for the provision of services on distributed clouds. This book provides a conceptual reference model for reliable capacity provisioning for distributed clouds and discusses how data analytics and machine learning, application and infrastructure optimization, and simulation can deliver quality of service requirements cost-efficiently in this complex feature space. These are illustrated through a series of case studies in cloud computing, telecommunications, big data analytics, and smart cities
Congress UPV Proceedings of the 21ST International Conference on Science and Technology Indicators
This is the book of proceedings of the 21st Science and Technology Indicators Conference that took place
in ValĂšncia (Spain) from 14th to 16th of September 2016.
The conference theme for this year, âPeripheries, frontiers and beyondâ aimed to study the development and
use of Science, Technology and Innovation indicators in spaces that have not been the focus of current indicator
development, for example, in the Global South, or the Social Sciences and Humanities.
The exploration to the margins and beyond proposed by the theme has brought to the STI Conference an
interesting array of new contributors from a variety of fields and geographies.
This yearâs conference had a record 382 registered participants from 40 different countries, including 23
European, 9 American, 4 Asia-Pacific, 4 Africa and Near East. About 26% of participants came from outside
of Europe.
There were also many participants (17%) from organisations outside academia including governments (8%),
businesses (5%), foundations (2%) and international organisations (2%). This is particularly important in a
field that is practice-oriented.
The chapters of the proceedings attest to the breadth of issues discussed. Infrastructure, benchmarking
and use of innovation indicators, societal impact and mission oriented-research, mobility and careers, social
sciences and the humanities, participation and culture, gender, and altmetrics, among others.
We hope that the diversity of this Conference has fostered productive dialogues and synergistic ideas and
made a contribution, small as it may be, to the development and use of indicators that, being more inclusive,
will foster a more inclusive and fair world
