- Abstract
- HistCite(TM) is a software tool for analyzing and visualizing direct citation linkages between scientific papers. Its inputs are bibliographic records (with cited references) from "Web of Knowledge" or other sources. Its outputs are various tables and graphs with informetric indicators about the knowledge domain under study. As an example we analyze informetrically the literature about Alexius Meinong, an Austrian philosopher and psychologist. The article shortly discusses the informetric functionality of "Web of Knowledge" and shows broadly the possibilities that HistCite offers to its users (e.g. scientists, scientometricans and science journalists).

- Abstract
- "Im 21. Jahrhundert ist die entscheidende Herausforderung an Informationsdienstleister nicht, Informationen zugänglich, sondern sie optimal nutzbar zu machen", sagt Sabine Brünger-Weilandt, Geschäftsführerin von FIZ Karlsruhe, das den Online-Dienst STN International in internationaler Kooperation betreibt. Informationsprofis, so Brünger-Weilandt weiter, bräuchten hockentwickelte Software für strategisches Informationsmanagement. Als "Antwort auf diesen Bedarf" hat STN International eine neue Software zur Analyse und Visualisierung (A&V) von Rechercheergebnissen aus STN-Datenbanken entwickelt. STN® AnaVistT(TM) wurde auf der DGI Online-Tagung Ende Mai in Frankfurt am Main und auf Benutzertreffen in Frankfurt am Main, München und Essen vorgestellt. Seit 18. Juli 2005 ist das neue A&V-Werkzeug für die öffentliche Nutzung freigegeben (www.stn-international.de).
Die wichtigsten Funktionen von STN AnaVist sind: - Inhalte aus mehreren Datenbanken sind gleichzeitig auswertbar - Nutzer können Daten aus unterschiedlichen Ouellen suchen, analysieren und visualisieren, u.a. aus der Chemiedatenbank CAplusSM, der Patentdatenbank PCTFULL, und US-amerikanischen Volltextdatenbanken. - Einzigartige Beziehungen zwischen Datenelementen-nur STN AnaVist bietet die Möglichkeit, Beziehungen zwischen sieben unterschiedlichen Feldern aus Datenbankdokumenten - z.B., Firmen, Erfindern, Veröffentlichungsjahren und Konzepten-darzustellen. - Gruppierung und Bereinigung von Daten - vor der Analyse werden Firmen und ihre unterschiedlichen Namensvarianten von einem "Company Name Thesaurus" zusammengefasst. - Konzept-Standardisierung - Durch das CAS-Vokabular werden Fachbegriffe datenbankübergreifend standardisiert, so dass weniger Streuung auftritt. - Interaktive Präsentation der Beziehungen zwischen Daten und Diagrammenwährend der Auswertung können Daten zum besseren Erkennen der Beziehungen farblich hervorgehoben werden. - Flexible Erstellung der auszuwertenden Rechercheergebnisse - Rechercheergebnisse, die als Ausgangsdatensatz für die Analyse verwendet werden sollen, können auf zwei Arten gewonnen werden: zum einen über die in STN® AnaVist(TM) integrierte Konzept-Suchfunktion, zum anderen durch problemlose Übernahme von Suchergebnissen aus der bewährten Software STN Express® with Discover! TM Analysis Edition, Version 8.0

- Abstract
- We explore the intellectual subject structure and research themes in software engineering through the identification and analysis of a core journal literature. We examine this literature via two expert perspectives: that of the author, who identified significant work by citing it (journal cocitation analysis), and that of the professional indexer, who tags published work with subject terms to facilitate retrieval from a bibliographic database (subject profile analysis). The data sources are SCISEARCH (the on-line version of Science Citation Index), and INSPEC (a database covering software engineering, computer science, and information systems). We use data visualization tools (cluster analysis, multidimensional scaling, and PFNets) to show the "intellectual maps" of software engineering. Cocitation and subject profile analyses demonstrate that software engineering is a distinct interdisciplinary field, valuing practical and applied aspects, and spanning a subject continuum from "programming-in-the-smalI" to "programming-in-the-large." This continuum mirrors the software development life cycle by taking the operating system or major application from initial programming through project management, implementation, and maintenance. Object orientation is an integral but distinct subject area in software engineering. Key differences are the importance of management and programming: (1) cocitation analysis emphasizes project management and systems development; (2) programming techniques/languages are more influential in subject profiles; (3) cocitation profiles place object-oriented journals separately and centrally while the subject profile analysis locates these journals with the programming/languages group

- Abstract
- Contributions of DRTC to informetric studies and research are discussed. A report on recent work - a quantitative country-wise analysis of software literature based on the data from two bibliographic databases i.e. COMPENDEX and INSPEC is presented. The number of countries involved in R & D activities in software in the most productive group is increasing. The research contribution on software is decreasing in developed countries as compared to that in developing and less developed countries. India 's contribution is only 1.1% and it has remained constant over the period of 12 years 1989-2001. The number of countries involved in R&D activities in software has been increasing in the 1990s. It is also noted that higher the budget for higher education, higher the number of publications; and that higher the number of publications, higher the export as well as the domestic consumption of software.

- Abstract
- In der Bibliometrie werden meist zwei Größen vermessen: die Anzahl von Publikationen und Zitationen. Publiziert und zitiert haben Menschen bereits sehr früh in der Geschichte. Schon in der Antike sind bei überlieferten Werken Zitationen zu finden. Der englische Begriff "Bibliometrics" selbst wurde aber erst 1969 definiert. In dem folgenden Artikel wird eine kleine Frühgeschichte der Bibliometrie, einer Unterdisziplin der Informationswissenschaft, bis zu diesem wichtigen Jahr anhand von beispielhaften Studien und Arbeiten dargestellt. Es wird auf die Anfänge von Publikationen und Zitationen und den fachlichen Rahmen der Bibliometrie eingegangen. Der Ursprung der Bibliometriegeschichte selbst wird von unterschiedlichen Autoren unterschiedlich früh angesetzt. Die verschiedenen Ansätze werden vorgestellt und diskutiert. Der Artikel schließt mit einer Beschreibung der wachsenden Bedeutung dieses Fachs im heutigen Informationszeitalter.

- Abstract
- This study examines whether there are some general trends across subject fields regarding the factors affecting the number of citations of articles, focusing especially on those factors that are not directly related to the quality or content of articles (extrinsic factors). For this purpose, from 6 selected subject fields (condensed matter physics, inorganic and nuclear chemistry, electric and electronic engineering, biochemistry and molecular biology, physiology, and gastroenterology), original articles published in the same year were sampled (n?=?230-240 for each field). Then, the citation counts received by the articles in relatively long citation windows (6 and 11 years after publication) were predicted by negative binomial multiple regression (NBMR) analysis for each field. Various article features about author collaboration, cited references, visibility, authors' achievements (measured by past publications and citedness), and publishing journals were considered as the explanatory variables of NBMR. Some generality across the fields was found with regard to the selected predicting factors and the degree of significance of these predictors. The Price index was the strongest predictor of citations, and number of references was the next. The effects of number of authors and authors' achievement measures were rather weak.

- Abstract
- Die Karte stellt für die deutschen Universitäten und einige zu Vergleichszwecken ausgewählte außeruniversitäre Forschungseinrichtungen vier bibliometrische Kennzahlen auf Grundlage von zbMATH-Daten dar: Die Zahl der 2010 publizierten Arbeiten (links oben) und ihre gesamten zugehörigen Zitationen (links unten) sowie die Zahl der 2014 publizierten Arbeiten (rechts oben) und ihre gesamten zugehörigen Zitationen (rechts unten). Die Zusammenfassung auf Universitätsebene begründet sich damit, dass mathematische Arbeiten an einer Universität ggf. von Mitgliedern verschiedener Einrichtungen und/oder Fakultäten geschrieben werden. Die unterschiedliche Struktur der einzelnen Universitäten macht einen Vergleich von Einzeleinrichtungen sehr aufwändig. Zu beachten ist auch, dass die inhärente Fehlerquote sowohl bei der Zuordnung von Referenzstrings zu Arbeiten als auch von Arbeiten zu Autoren und Institutionen sich bei den Gesamtzahlen zu einer Abweichung von bis zu 20 % kumulieren kann. Die Jahre 2010 und 2014 wurden gewählt, da zum einen nach vier Jahren ein signifikanter Anteil der Zitationen relativ zum Publikationswachstum verfügbar ist (vgl. Abb. 4 auf S. 211), zum anderen für 2014 zumindest die Publikationsdaten einschließlich gedruckter Konferenzbände weitgehend vollständig erfasst sind (s. Anmerkung 2 auf Seite S. 213).

- Abstract
- Science mapping aims to build bibliometric maps that describe how specific disciplines, scientific domains, or research fields are conceptually, intellectually, and socially structured. Different techniques and software tools have been proposed to carry out science mapping analysis. The aim of this article is to review, analyze, and compare some of these software tools, taking into account aspects such as the bibliometric techniques available and the different kinds of analysis.

- Abstract
- Unter kognitiver Mobilität verstehe ich im folgenden nicht die Mobilität von Information, sondern die Bewegung des Denkens, und zwar hier des wissenschaftlichen Denkens. Wissenschaftliches Denken vollzieht sich disziplinär sowie interdisziplinär, im informationellen Austausch von Disziplinen und Forschungsgebieten. Dieser Austausch unterliegt, wie die Wissenschaftsgeschichte lehrt, einer Entwicklungsdynamik, die als Abfolge von Wanderungen oder Übergängen zwischen Forschungsgebieten in folgendem Sinn verständen werden kann. Beschäftigt sich ein Forscher A zum Zeitpunkt t1 mit Forschungsgebiet X und zum Zeitpunkt t2 als nächstes mit Forschungsgebiet Y, so liegt ein Übergang von X nach Y vor. Gibt es für diese Art von Übergängen charakteristische Eigenschaften oder Regularitäten.> Ein wichtiges Merkmal solcher Übergänge ist der Grad der Verwandtschaft, der kognitiven Affinität zwischen Ausgangs- und Zielgebiet der Migration. Am Beispiel der rund 150.000 Migrationen zwischen den mathematischen Subdisziplinen, wie sie sich in den Zeitschriftenartikel-Nachweisen der Mathematical Reviews von 1959 bis 1975 widerspiegeln, wurde das Verhältnis von kognitiver Mobilität und Affinität empirisch systematisch untersucht. Es bestätigte sich George K. Zipfs "Principle of Least Effort". Zählreiche Mechanismen und Faustregeln der Wissensorganisation dürften der Wirksamkeit dieses Prinzips zugrundeliegen.

- Abstract
- This article presents a new open-source software tool, SciMAT, which performs science mapping analysis within a longitudinal framework. It provides different modules that help the analyst to carry out all the steps of the science mapping workflow. In addition, SciMAT presents three key features that are remarkable in respect to other science mapping software tools: (a) a powerful preprocessing module to clean the raw bibliographical data, (b) the use of bibliometric measures to study the impact of each studied element, and (c) a wizard to configure the analysis.

- Abstract
- Wissenschaftliche Institutionen und einzelne WissenschaftlerInnen werden zunehmend nach bibliometrischen Daten beurteilt. Jeder Mathematiker hat Vorbehalte gegenüber dieser Praxis. Über diese beiden Dinge waren sich alle TeilnemerInnen und Wortmeldungen des Panels zur Bibliometrie auf der DMV-Jahrestagung in Salzburg einig. Für einzelne WissenschaftlerInnen hat die IMU bereits 2014 (tinyurl.com/ycd7wvh7) die Vorbehalte gegenüber rein bibliometrischen Beurteilungen klar formuliert. Universitätsleitungen, Politik und andere bis hin zur öffentlichen Diskussion verlassen sich aber teilweise aif diese Art der Bewertung. Konkret kann das so aussehen: Zur Beurteilung von Departements zählt eine Universität Publikationen und gewichtet sie nach ihrer Güte. Die Güte entnimmt man einer Einteilung von Fachzeitschriften etwa in A, B und C. Liegt eine solche Einteilung nicht vor, sind alle Journale des Faches mit 1 gewichtet, d.h. 'junk'. Die Diskrepanz zwischen unserer Einschätzung und der allgemeinen Wirkmächtigkeit von Biblimetrie wirft für die DMV als Fachgegsellschaft die Frage auf, wie sie Einfluss nehmen kann und soll. Die 'Mitteilungen' versuchen an dieser Stelle zunächst, ein möglichst breites Meinungsbild zu sammeln. Wir haben sieben Fragen an eine Reihe von Kolleginnen und Kollegen gestellt, die am Panel teilgenmmen haben oder aus anderen Gründen mit dem Thema besfasst sind.

- Abstract
- Newby, Greenberg, and Jones analyze programming productivity of open source software by counting registered developers contributions found in the Linux Software Map and in Scourceforge. Using seven years of data from a subset of the Linux directory tree LSM data provided 4503 files with 3341 unique author names. The distribution follows Lotka's Law with an exponent of 2.82 as verified by the Kolmolgorov-Smirnov one sample goodness of fit test. Scourceforge data is broken into developers and administrators, but when both were used as authors the Lotka distribution exponent of 2.55 produces the lowest error. This would not be significant by the K-S test but the 3.54% maximum error would indicate a fit and calls into question the appropriateness of K-S for large populations of authors.
