Reflections on receiving the ASIS&T 2016 Award of Merit
No full textAt the ASIS&T Annual Meeting in Copenhagen, Peter Ingwersen expressed surprise and gratitude for being honored with the Association’s 2016 Award of Merit. The professor emeritus from Denmark’s Royal School of Library and Information Science thanked peers for recognizing him as a mentor and research originator. Ingwersen observed that his own areas of research in interactive information retrieval (IR) and scientometrics/webometrics have come together as converging lines of interest, though research and analysis are often restricted by system and feature limitations. Experimentation, Ingwersen stated, is too little focused on the effective workings of IR models and contexts, repeatability and negative research results, and is instead constrained by practicalities and pragmatics. Ingwersen expressed pleasure at the acceptance of web redundancy, citing his theory of polyrepresentation and noting the value of weighting term and search results underlying ranking of web search results. He credited the ASIS&T meetings and publications for developments stemming from original IR experimental studies. (Editor's Summary

A context-driven integrated framework for research on interactive IR
No full textThis paper discusses the Integrated Research Framework for Information Seeking and Retrieval (ISR) originating from (Ingwersen & Järvelin, 2005) by comparing it to the Laboratory Research Framework for IR and two nested models of contexts involved in ISR: that of Kekäläinen & Järvelin (2002), based on work task activities, and the model by Ingwersen (2007) focusing on contexts to information objects. In addition the relevance model by Cosijn (2004), also of nested nature, is discussed, leading forward to the nine dimensions of research variables, potentially influencing ISR processes and evaluation
A New Centrality Measure for Social Network Analysis Applicable to Bibliometric and Webometric Data
No full textIn the literature there are a large number of publications in sociology, in computer science or in information sciences, as well as in studies of collaboration in science describing the studies of social networks with unweighted ties because measures involving unweighted ties are easier to calculate. It is not surprising that there are few studies on networks with weighted ties since they not only need more complex formulas but need a process of quantification when quantitative empirical data are not directly available.
However quantitative empirical data are directly available under the condition of using bibliometric or webometric data.
In conclusion new complex measures of the degree centrality are introduced including weighted ties possible for use of the analysis of co-authorship or citation networks. Both co-authorship relations and citations are well quantified data (weighted ties).
These new measures are applied to a co-authorship network as an exampl
Moral Good, the Beatific Vision, and God’s Kingdom Writings by Germain Grisez and Peter Ryan, S.J.. Edited by Peter J. Weigel
No full textFor close to half a century, the work of Germain Grisez has been highly influential, and his writings continue to receive considerable attention from philosophers and theologians of diverse viewpoints. His co-author for this work is the professor and noted moral theologian Fr. Peter Ryan, S.J., currently the executive director of the Secretariat of Doctrine and Canonical Affairs of the United States Conference of Catholic Bishops (USCCB). These two eminent scholars explore fundamental questions about Christian eschatology, moral theory, the purpose of human life, and the promise of human fulfilment. The authors examine Christian teaching on the final destiny of persons, investigating the meaning of God's kingdom, the hope of the beatific vision, and the centrality of moral goodness and divine grace in one's final end. This work is an ideal source for students, scholars, ministers and lay persons interested in basic questions of Christian theology, the philosophy of religion, ethical theory, and Catholic doctrin

Scientometric Indicators and Webometrics - and the Polyrepresentation Principle in Information Retrieval
No full textThis book contains the text of three lectures from the 28th Sarada Ranganathan Endowment Lectures, held in Bangalore in December 2010. The lectures were delivered by Dr. Peter Ingwersen, Professor at the Danish School of Library and Information Science, Copenhagen. The first lecture on scientometric indicators presented two fundamental models of scientific communication: the classic one - mainly providing access to document records in library catalogues and bibliographic databases - and the digitized one - relying on open access and diversified document access potentials. The lecture contextualizes, characterizes, and exemplifies the concept of 'scientometrics.' The second lecture on the range of webometrics provided insights into the history of webometrics in context of other research evaluation methods. The lecture exemplified selected cases, both from traditional webometric analyses and new ones based on scientific dataset usage and comparisons of link and download/reading patterns for newspapers. The third lecture on poly-representation provides an integrated and explicitly cognitive framework for understanding the process involved in information retrieval. The lecture outlined the principle of poly-representation with a focus on the kinds of representations involved. The potentials, strengths, and problems of applying the principle are discussed in the light of recent studies. The challenges and opportunities for future research are identified along a poly-representation continuum <br/
Citations and references as keys to relevance ranking in interactive IR
No full textAccording to the principle of Polyrepresentation (Ingwersen & Järvelin, 2005; Ingwersen, 2012) bibliographic references in scientific documents as well as citations to documents have the potential of serving as useful features for re-ranking of retrieved documents. References (and thus citations) can be seen as footprints of information interaction, because of the behavioral conventions built in to the scientific communication and publication process. They are manifestations of degrees of utility of methods, results and ideas made earlier on by other scientists. The use of references in IR has been demonstrated to improve retrieval performance (Skov et al. 2008), whereas the number of citations has not provided similar improvements. The presentation will discuss the following phenomena and characteristics of references and citations as means for relevance re-ranking: 1) Are academic references (and thus citations) associated with relevance? 2) What are their potentials for IR? 3) What are their limitations? The presentation will propose a range of potentials and provide an initial research design. Selected cases are exemplified from the Web of Science database. <br/
