- Abstract
- Detecting science-technology hierarchical linkages is beneficial for understanding deep interactions between science and technology (S&T). Previous studies have mainly focused on linear linkages between S&T but ignored their structural linkages. In this paper, we propose a network coupling approach to inspect hierarchical interactions of S&T by integrating their knowledge linkages and structural linkages. S&T knowledge networks are first enhanced with bidirectional encoder representation from transformers (BERT) knowledge alignment, and then their hierarchical structures are identified based on K-core decomposition. Hierarchical coupling preferences and strengths of the S&T networks over time are further calculated based on similarities of coupling nodes' degree distribution and similarities of coupling edges' weight distribution. Extensive experimental results indicate that our approach is feasible and robust in identifying the coupling hierarchy with superior performance compared to other isomorphism and dissimilarity algorithms. Our research extends the mindset of S&T linkage measurement by identifying patterns and paths of the interaction of S&T hierarchical knowledge.

- Abstract
- Der Fachinformationsdienst (FID) Pharmazie verfolgt das Ziel, die Informationsinfrastruktur und die Literaturversorgung für die pharmazeutische Hochschulforschung nachhaltig zu verbessern. Das Projekt wird seit dem 1. Januar 2015 von der Deutschen Forschungsgemeinschaft gefördert. Eine Besonderheit stellt die Kooperation zwischen der Universitätsbibliothek Braunschweig und dem Institut für Informationssysteme (IfIS) der TU Braunschweig dar, wodurch aktuelle Forschung auf dem Gebiet der Informatik in die Implementierung innovativer FID-Dienste mündet. Im Zentrum des Projektes steht der nutzerzentrierte Aufbau einer erweiterbaren und personalisierbaren Informationsinfrastruktur. Das vom FID entwickelte Discovery System "PubPharm" zur pharmaziespezifischen Recherche basiert, als Weiterentwicklung des beluga-Systems der SUB Hamburg, auf der Open Source Software VuFind. Als Datengrundlage enthält es u.a. die Medline Daten, erweitert durch Normdaten, die unter anderem die Suche nach chemischen Strukturen erlauben. Gleichzeitig werden vom Institut für Informationssysteme innovative Suchmöglichkeiten basierend auf Narrativer Intelligenz untersucht und perspektivisch in das Retrieval des Discovery Systems eingebunden. Im Rahmen von sog. FID-Lizenzen bietet der FID Pharmazie Wissenschaftlern/innen Volltextzugriff auf pharmazeutische Fachzeitschriften. Bestandteil der Lizenzen ist das Recht zur Langzeitarchivierung. Bei deren technischer Umsetzung kooperiert der FID mit der TIB Hannover. Der FID Pharmazie koppelt seine Aktivitäten eng an die pharmazeutische Fachcommunity: unter anderem begleitet ein Fachbeirat die Entwicklungen. Im Rahmen der Öffentlichkeitsarbeit werden Nutzer/innen umfassend über die Angebote informiert, u.a. in Webcasts und im PubPharm Blog.

- Abstract
- PageRank is defined as the stationary state of a Markov chain. The chain is obtained by perturbing the transition matrix induced by a web graph with a damping factor alpha that spreads uniformly part of the rank. The choice of alpha is eminently empirical, and in most cases the original suggestion alpha=0.85 by Brin and Page is still used. Recently, however, the behaviour of PageRank with respect to changes in alpha was discovered to be useful in link-spam detection. Moreover, an analytical justification of the value chosen for alpha is still missing. In this paper, we give the first mathematical analysis of PageRank when alpha changes. In particular, we show that, contrarily to popular belief, for real-world graphs values of alpha close to 1 do not give a more meaningful ranking. Then, we give closed-form formulae for PageRank derivatives of any order, and an extension of the Power Method that approximates them with convergence O(t**k*alpha**t) for the k-th derivative. Finally, we show a tight connection between iterated computation and analytical behaviour by proving that the k-th iteration of the Power Method gives exactly the PageRank value obtained using a Maclaurin polynomial of degree k. The latter result paves the way towards the application of analytical methods to the study of PageRank.

- Abstract
- Künstliche Intelligenz kann lernen anhand von Erfahrungen und Vorgaben. Das Problem ist aber, dass sich maschinelles Lernen zwar in eine bestimmte Richtung steuern lässt, um bestimmte Probleme zu lösen, dass aber der Programmierer mitunter nicht mehr weiß, was in dem "künstlichen Gehirn" bzw. dem neuronalen Netzwerk vor sich geht, das mit zunehmender Komplexität und Lernerfahrung für den Menschen zur Black Box wird, wo man nur sehen kann, was an Daten einfließt und was herauskommt.
