Finding Academic Experts on a MultiSensor Approach using Shannon's Entropy
Expert finding is an information retrieval task concerned with the search for
the most knowledgeable people, in some topic, with basis on documents
describing peoples activities. The task involves taking a user query as input
and returning a list of people sorted by their level of expertise regarding the
user query. This paper introduces a novel approach for combining multiple
estimators of expertise based on a multisensor data fusion framework together
with the Dempster-Shafer theory of evidence and Shannon's entropy. More
specifically, we defined three sensors which detect heterogeneous information
derived from the textual contents, from the graph structure of the citation
patterns for the community of experts, and from profile information about the
academic experts. Given the evidences collected, each sensor may define
different candidates as experts and consequently do not agree in a final
ranking decision. To deal with these conflicts, we applied the Dempster-Shafer
theory of evidence combined with Shannon's Entropy formula to fuse this
information and come up with a more accurate and reliable final ranking list.
Experiments made over two datasets of academic publications from the Computer
Science domain attest for the adequacy of the proposed approach over the
traditional state of the art approaches. We also made experiments against
representative supervised state of the art algorithms. Results revealed that
the proposed method achieved a similar performance when compared to these
supervised techniques, confirming the capabilities of the proposed framework
ProcessPageRank - A Network-based Approach to Process Prioritization Decisions
Deciding which business processes to improve first is a challenge most corporate decision-makers face. The literature offers many approaches, techniques, and tools that support such process prioritization decisions. Despite the broad knowledge about measuring the performance of individual processes and determining related need for improvement, the interconnectedness of processes has not been considered in process prioritization decisions yet. So far, the interconnectedness of business processes is captured for descriptive purposes only, for example in business process architectures. This drawback systematically biases process prioritization decisions. As a first step to address this gap, we propose the ProcessPageRank (PPR), an algorithm based on the Google PageRank that ranks processes according to their network-adjusted need for improvement. The PPR is grounded in the literature related to process improvement, process performance measurement, and network analysis. For demonstration purposes, we created a software prototype and applied the PPR to five process network archetypes to illustrate how the interconnectedness of business processes affects process prioritization decisions
Comparison of USA and UK rankings of LIS journals
Purpose – The purpose of this paper is to investigate UK academics’ views of the importance and prestige of
journals relevant to library and information science (LIS) teaching and research.
Design/methodology/approach – A questionnaire, based on one used previously in the USA, was sent to
UK academics involved in LIS teaching and research. The questionnaire asked respondents to rate the
importance of 87 LIS journals, to suggest others that were of importance to them but that were not amongst
the 87, and to identify the five most prestigious journals for promotion purposes. In addition, those journals
were identified that had figured in institutional submissions to the LIS Unit of Assessment in Research
Excellence Framework (REF).
Findings – While there was a fair measure of overall agreement between US and UK rankings of the
87 journals, with both highlighting the standing of the Journal of the Association for Information Science and
Technology and of the Journal of Documentation, some substantial differences were also noted. Evidence is
presented for a strong locational component to academics’ assessments of journal prestige, and analysis of the
REF2014 submissions demonstrates the highly inter-disciplinary nature of LIS research in the UK.
Research limitations/implications – The sample size is small, comprising 30 completed responses.
Originality/value – This is the first study to report UK academics’ rankings of LIS journals, and to compare
those with comparable data for US academics
Quantifying Success in Science: An Overview
Quantifying success in science plays a key role in guiding funding
allocations, recruitment decisions, and rewards. Recently, a significant amount
of progresses have been made towards quantifying success in science. This lack
of detailed analysis and summary continues a practical issue. The literature
reports the factors influencing scholarly impact and evaluation methods and
indices aimed at overcoming this crucial weakness. We focus on categorizing and
reviewing the current development on evaluation indices of scholarly impact,
including paper impact, scholar impact, and journal impact. Besides, we
summarize the issues of existing evaluation methods and indices, investigate
the open issues and challenges, and provide possible solutions, including the
pattern of collaboration impact, unified evaluation standards, implicit success
factor mining, dynamic academic network embedding, and scholarly impact
inflation. This paper should help the researchers obtaining a broader
understanding of quantifying success in science, and identifying some potential
research directions

A review of the characteristics of 108 author-level bibliometric indicators
An increasing demand for bibliometric assessment of individuals has led to a
growth of new bibliometric indicators as well as new variants or combinations
of established ones. The aim of this review is to contribute with objective
facts about the usefulness of bibliometric indicators of the effects of
publication activity at the individual level. This paper reviews 108 indicators
that can potentially be used to measure performance on the individual author
level, and examines the complexity of their calculations in relation to what
they are supposed to reflect and ease of end-user application.Comment: to be published in Scientometrics, 201
