Knowledge-based management of research results in process sciences on the basis of ontologies with a focus on model development
No full textDie Verfügbarkeit von Ergebnissen aus Forschung und Entwicklung stellt große Anforderungen an die betreffenden Institutionen, sowohl in organisatorischer als auch in technischer Hinsicht. Die Vielzahl wissenschaftlicher Untersuchungen, der teilweise hohe Grad an Spezialisierung und die Tatsache, dass gerade grundlagenorientierter Arbeiten über einen längeren Zeitraum relevant sein können, führen zu der Notwendigkeit einer effektiven Verwaltung anfallender Ergebnisse. Im Rahmen dieser Arbeit wurde ein Ansatz entwickelt, der die nachhaltige Verwaltung von For-schungsergebnissen aus den Prozesswissenschaften (Verfahrenstechnik, Chemieingenieurwesen und verwandte Gebiete) mit Hilfe von Wissensmodellen, sog. Ontologien, ermöglicht. Den zentralen Ansatz für die formale Beschreibung von Aussagen über wissenschaftliche Ergeb-nisse bildet die Betrachtung mathematischer Modelle. Letztere sind Ziel, Mittel und/oder Aus-gangspunkt vieler wissenschaftlicher Untersuchungen gerade im Bereich der Prozesswissenschaf-ten. Neben der fachlich-inhaltlichen Beschreibung von relevanten Konzepten wie mathematischen Modellen, Messdaten, Dokumenten, etc. steht das Erfassen von Bezügen zwischen unterschiedli-chen Ansätzen im Vordergrund. Zu diesem Zweck wurde der sog. SchoolOnto-Ansatz (vgl. Bu-ckingham et al., 2000) zur formalen Repräsentation von Aussagen im Sinne eines wissenschaftli-chen Diskurses übernommen und auf die gegebene Problemstellung übertragen. Als softwaretechnische Umsetzung dieses Ansatzes wurde das System SCIFORG entworfen. Es wurde auf der Grundlage des Ontologie-Editors Protégé implementiert. SCIFORG bietet An-wendern verschiedene Schnittstellen für das Editieren von Daten und die Suche in der Wissens-basis sowie eine Reihe von fachspezifischen Funktionen wie etwa die Einheiten-Verwaltung. Das System unterstützt die Verwaltung großer Datenmengen. Das SCIFORG System in Verbindung mit dem zugrunde liegenden Ansatz erlaubt es Anwen-dern, wissenschaftliche Ergebnisse durch semantische Informationen anzureichern. Damit lassen sich Zusammenhänge nachvollziehen und Forschungsergebnisse gezielt recherchieren.The availability of resources resulting from scientific work and development activities poses a great challenge to the respective institutions. This concerns technical as well as organizational aspects. The high number of research activities, the high degree of specialism as well as the fact that results can be relevant for a long period of time demand for the efficient management of scientific resources. This thesis presents an approach for the sustainable management of results in the field of process sciences (chemical engineering and related areas). The approach is based on knowledge models, so called ontologies, whereas the focus in respect of content is on mathematical models. The latter form the goal, the starting point and/or the means of many scientific analyses – especially in the area of process sciences. Apart from the domain-specific description of relevant concepts such as mathematical models, experimental data sets, documents, etc. this work focuses on formal statements about how scien-tific approaches are related. To achieve this, the so called SchoolOnto-approach (vgl. Bucking-ham et al., 2000) was adopted and modified. The approach was implemented as the SCIFORG software system, which is based on the ontol-ogy-editor Protégé. SCIFORG provides a couple of interface to edit data and search the knowl-edge base. The system offers several domain-specific interfaces such as for the management of physical units. The system is suited for large amounts of data. SCIFORG enables users to enrich scientific results by semantic information. Thus relations be-tween different scientific results can be retraced. The results themselves can be retrieved with high precision
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Full text linkWe 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
Semantic Technologies in the SIMDAT Grid Project
Full text linkThe SIMDAT project aims at developing generic grid technology for the solution of complex application problems and using this new technology in several industrial application sectors. Semantic technologies are expected to offer a significant added value to other technologies with respect to the management of resources on the process level and on the data level. The strategic objectives of SIMDAT are (i) to test and enhance data grid technology for product development and production process design, (ii) to develop federated versions of problem-solving environments (PSEs) by leveraging enhanced grid services, (iii) to exploit data grids as a basis for distributed knowledge discovery, (iv) to promote de facto standards for these enhanced grid technologies across a range of disciplines and sectors as well as (v) to raise awareness for the advantages of data grids in important industrial sectors
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
