Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
S18. Our little minions, part 3: small tools with major impact (Other)
No full textIn our daily work, small self-made scripts, home-grown small applications and small hardware devices significantly help us to get work done. These little helpers – “little minions” – often reduce our workload or optimise our workflows, although they are not often presented to the outside world and the research community. Instead, we generally focus on presenting the results of our research and silently use our small tools during our research, without even pointing to them, and especially not to the source code or building instructions.
This session will focus on these small helpers – “little minions” – and we invite researchers to share their tools, so that the scientific community may benefit and – perhaps – spontaneously create “special minion interest groups”.
As we have seen in previous year’s “minion talks” there are a wide range of tools to be shared. These may be perfect examples for your own minion creation. A constantly expanding list of little minions can be found at https://github.com/caa-minions/minions.
At CAA2018 in Tübingen, a normal session (see S6 [LH18]) spontaneously became a “Stand-up-Minion” lightning talk with a lot of nice pieces of source code, small tools and open/free software extensions for proprietary products. In 2018 we saw a tool for photogrammetric rectification of profile images of archaeological excavations, digital tools behind Bonify, and database solutions for excavations.
In Krakow at CAA2019, a lot of little minions of various research domains were published to the research community (see O29 [JUK19]). Martina Trognitz gave a deeper insight into Wikidata as a LOD minion addressing a “Linked and Open Bibliography for Aegean Glyptic in the Bronze Age”. In terms of text mining, Ronald Visser showed his “little text mining minion”. Florian Thiery and Allard Mees presented two small time minions to tame relative chronology and vague information in graph modelling using “Taming Time Tools: Alligator and Academic Meta Tool”. A minion to do “serial, fast and low cost 3D pottery on site documentation” was presented by Fanet Göttlich. Furthermore, Bart Vissers presented the minion “CpyPst3D: a tool for direct exchange of 3D features with attributes between GIS, 3D-modelling environment and CAD”. Spontaneous minions were additions to profileAAR by Moritz Mennenga, the use of Heurist for collecting minions by Ian Johnson, and a little minion by Gary Nobles to create a 3D volume object from point clouds of laser scans of excavation trenches.
This session invites short presentations, lightning talks – aka “minion talks” (max. 10 minutes including very short discussion) – of small coding pieces, software or hardware solutions, not only focusing on field work or excavation technology, associated evaluation or methodical approaches in data driven archaeology. Each “minion talk” should explain the innovative character and mode of operation of the digital tool. The only restriction is that the software, source code and/or building instructions are open and are or will be freely available (e.g. GitHub, GitLab, etc.). Proprietary products cannot be presented, but only open and freely available tools designed for them.
We invite speakers to submit a short abstract including an introduction into the tool, the link to the repository to get access to the source code and an explanation as to which group of researchers could benefit from the little minion and how. The tools may address the following issues, but are not limited to: data processing tools and algorithms, measuring tools, digital documentation tools, GIS-Plugins, hands-on digital inventions (for excavations), and data driven tools (e.g. Linked Data, CSV, Big Data). After previous years’ (pt.1 at CAA2017 Tübingen and pt.2 at CAA2018 Krakow) spontaneous success of “Stand-up-Science”, you will also have the opportunity to spontaneously participate and demonstrate what you have on your stick or laptop. If you want to participate without an abstract in the spontaneous section of the session, please send an email to us (even shortly before the conference). Please come and spontaneously introduce your little minion!
The minion session is designed for technically interested researchers of all domains who want to present their small minions with the focus on the technical domain and also for researchers who want to get ideas about what kinds of little minions are available to help in their own research questions, with the possibility to create spontaneously little minion special interest groups. All of us use minions in our daily work, and often tools for the same task are built multiple times. The reason for this reproduction is often that the focus in talks are on the projects, and not on the technical details. This session provides a slot for these tools that are considered too unimportant to be presented in the normal talks, but take important and extensive steps in our research.
As an outcome of the session, all presented tools and links to code repositories will be available for the CAA research community. We will also collect all little minions in a “CAA little minion catalogue” (http://littleminions.link) available for the public and extended in the future on a GitHub repository at https://github.com/caa-minions/minions.

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Zwischen Elbe und Ems: Die Siedlungen der Trichterbecherkultur in Nordwestdeutschland
Get PDFIm vorliegenden Band werden verschiedene trichterbecherzeitliche Fundplätze Nordwestdeutschlands aus siedlungsarchäologischer Perspektive vorgelegt. Moritz Mennenga kombiniert Fund- und Befundanalysen mit aktuellen naturwissenschaftlichen Datierungen. Dies ermöglicht eine veränderte Sicht auf die Trichterbecher-Westgruppe. Vor allem die Auseinandersetzung mit Architektur und Funktion der Westgruppen-Häuser hat ein neues Bild der Hausentwicklung erzeugt. Weitblickend gelingt es ihm, diese in einen europäischen Rahmen zu stellen und dabei Verbindungen zum nordwesteuropäischen Raum darzulegen. Während also einerseits großräumige Bezüge hergestellt werden können, ermöglicht die detaillierte Analyse der Fundverteilungen andererseits teils überraschende Rekonstruktionen von Aktivitäts- und Abfallzonen – z. B. in der Siedlung Lavenstedt. Auch ein neuer Blick auf Siedlungsbestattungen und „Kulthäuser“ trägt zum besseren Verständnis der mittelneolithischen Lebenssituation in Nordwestdeutschland bei.This volume presents various Funnel Beaker period sites in north-west Germany from a settlement archaeological perspective. Moritz Mennenga combines analyses of finds and features with current scientific dating. This enables a new perspective on the Western Funnel Beaker group. Above all, the analysis of the architecture and function of the west group houses has created a new picture of the development of the houses. With far-sightedness, he succeeds in placing them in a European context and demonstrating connections to north-west Europe. While, on the one hand, large-scale references can be established, the detailed analysis of the distribution of finds also enables the sometimes surprising reconstruction of activity and waste zones – e.g. in the Lavenstedt settlement. A new look at settlement burials and ‘cult houses’ also contributes to a better understanding of the Middle Neolithic living situation in north-west Germany
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
