Studying Bibliometrics-Based Heuristics (BBHs): A New Research Program on the use of Bibliometrics in Research Evaluation

Lutz Bornmann
2020 Scholarly Assessment Reports  
Bornmann and Marewski (2019) suggest that these and similar questions can be empirically answered by studying the evaluative use of bibliometrics within the heuristics research program conceptualized by  ...  How do decision makers in science use bibliometric indicators and how do they rely on the indicators? Could bibliometric indicators replace the decision makers' judgments (partly or completely)?  ...  The authors conceptualize the use of bibliometrics in research evaluation based on the heuristics research program and introduce the term BBH.  ...

Bibliometrics-based decision trees (BBDTs) based on bibliometrics-based heuristics (BBHs): Visualized guidelines for the use of bibliometrics in research evaluation

Lutz Bornmann
2019 Quantitative Science Studies  
In so doing, heuristics can not only reduce complexity, but also boost the accuracy of decisions, their speed, and transparency.  ...  The BBDT exemplarily presented in this paper can be used as a guidance to find an answer on the question in which situations simple indicators such as mean citation rates are reasonable and in which situations  ...  The use of simple citation rates for research evaluation might lead to distorted world views if units are active in multiple fields.  ...

Natural frequencies improve Bayesian reasoning in simple and complex inference tasks

Ulrich Hoffrage, Stefan Krauss, Laura Martignon, Gerd Gigerenzer
2015 Frontiers in Psychology  
In Study 2, we show that teaching natural frequencies for simple tasks with one dichotomous cue and two hypotheses leads to a transfer of learning to complex tasks with three cue values and two cues, with  ...  Yet all the research and applications so far have been limited to situations where one dichotomous cue is used to infer which of two hypotheses is true.  ...  That is, it is largely sufficient to instruct people in using natural frequencies in the basic task in order to ensure a generalization to and solution of complex tasks, as long as the information in both  ...

AFSCN scheduling: How the problem and solution have evolved

Laura Barbulescu, Adele Howe, Darrell Whitley
2006 Mathematical and computer modelling  
Our evaluation of solutions focus on three algorithms: local search, Gooley's algorithm from AFIT, and the Genitor genetic algorithm.  ...  We compared data sets from 1992 and from 2002/2003 and found significant differences in the problems.  ...  The task requests in the current data interact in more complex ways, and the simple heuristic cannot always find the best solution.  ...

Confidence in heuristic solutions?

Kenneth Carling, Xiangli Meng
2015 Journal of Global Optimization  
The optimum is sought iteratively and pre-setting the number of iterations dominates in operations research applications, which implies that the quality of the solution cannot be ascertained.  ...  Deterministic bounds offer a mean of ascertaining the quality, but such bounds are available for only a limited number of heuristics and the length of the interval may be difficult to control in an application  ...  Acknowledgement We are grateful to Mengjie Han, Johan Håkansson and Daniel Wikström for comments on an earlier draft of the paper.  ...

The Optimality of Satisficing Solutions [article]

Othar Hansson, Andy Mayer
2013 arXiv   pre-print
This paper addresses a prevailing assumption in single-agent heuristic search theory- that problem-solving algorithms should guarantee shortest-path solutions, which are typically called optimal.  ...  Optimality implies a metric for judging solution quality, where the optimal solution is the solution with the highest quality.  ...  In addition, we would like to thank Rich Korf, Beth Mayer, and Risto Miikkulainen who commented on earlier drafts of this paper.  ...
