We present a supervised machine learning AND system which tackles semantic similarity between publication titles by means of word embeddings. Word embeddings are integrated as external components, which keeps the model small and efficient, while allowing for easy extensibility and domain adaptation. Initial experiments show that word embeddings can improve the Recall and F score of the binary classification sub-task of AND. Results for the clustering sub-task are less clear, but also promising and overall show the feasibility of the approach.
The demo presents a minimalist, off-the-shelf AND tool which provides a fundamental AND operation, the comparison of two publications with ambiguous authors, as an easily accessible HTTP interface. The tool implements this operation using standard AND functionality, but puts particular emphasis on advanced methods from natural language processing (NLP) for comparing publication title semantics.
Dieser Beitrag widmet sich der Analyse des Zusammenspiels sprachlich-hörbarer und sichtbar-kinesischer Praktiken, die beim alltäglichen Erzählen eingesetzt werden. Im Rahmen einer konversationsanalytisch basierten Untersuchung von Videoaufnahmen deutscher Alltagsgespräche wird die Bandbreite alltäglicher narrativer Praktiken in der face-to-face-Kommunikation aufgezeigt. Dies erfolgt exemplarisch anhand zweier Beispiele, in denen Einstieg, Ausgestaltung sowie Beendigung der Erzählung unter unterschiedlichen sequentiellen und multimodalen Bedingungen vollzogen werden. Die Untersuchung unterstreicht einerseits die Indexikalität alltäglicher narrativer Praktiken, andererseits die Notwendigkeit einer interaktionalen Narratologie, die diese Praktiken als Produkt sprachlicher, verkörperter und räumlicher Ressourcen sowie der Zusammenarbeit mehrerer Teilnehmer analysiert und konzeptualisiert.
The use of digital resources and tools across humanities disciplines is steadily increasing, giving rise to new research paradigms and associated methods that are commonly subsumed under the term digital humanities. Digital humanities does not constitute a new discipline in itself, but rather a new approach to humanities research that cuts across different existing humanities disciplines. While digital humanities extends well beyond language-based research, textual resources and spoken language materials play a central role in most humanities disciplines.
The ISOcat registry reloaded
(2012)
The linguistics community is building a metadata-based infrastructure for the description of its research data and tools. At its core is the ISOcat registry, a collaborative platform to hold a (to be standardized) set of data categories (i.e., field descriptors). Descriptors have definitions in natural language and little explicit interrelations. With the registry growing to many hundred entries, authored by many, it is becoming increasingly apparent that the rather informal definitions and their glossary-like design make it hard for users to grasp, exploit and manage the registry’s content. In this paper, we take a large subset of the ISOcat term set and reconstruct from it a tree structure following the footsteps of schema.org. Our ontological re-engineering yields a representation that gives users a hierarchical view of linguistic, metadata-related terminology. The new representation adds to the precision of all definitions by making explicit information which is only implicitly given in the ISOcat registry. It also helps uncovering and addressing potential inconsistencies in term definitions as well as gaps and redundancies in the overall ISOcat term set. The new representation can serve as a complement to the existing ISOcat model, providing additional support for authors and users in browsing, (re-)using, maintaining, and further extending the community’s terminological metadata repertoire.
The transfer of research data management from one institution to another infrastructural partner is all but trivial, but can be required, for instance, when an institution faces reorganization or closure. In a case study, we describe the migration of all research data, identify the challenges we encountered, and discuss how we addressed them. It shows that the moving of research data management to another institution is a feasible, but potentially costly enterprise. Being able to demonstrate the feasibility of research data migration supports the stance of data archives that users can expect high levels of trust and reliability when it comes to data safety and sustainability.
Although there is a growing interest of policy makers in higher education issues (especially on an international scale), there is still a lack of theoretically well-grounded comparative analyses of higher education policy. Even broadly discussed topics in higher education research like the potential convergence of European higher education systems in the course of the Bologna Process suffer from a thin empirical and comparative basis. This paper aims to deal with these problems by addressing theoretical questions concerning the domestic impact of the Bologna Process and the role national factors play in determining its effects on cross-national policy convergence. It develops a distinct theoretical approach for the systematic and comparative analysis of cross-national policy convergence. In doing so, it relies upon insights from related research areas — namely literature on Europeanization as well as studies dealing with cross-national policy convergence.
Just like most varieties of West Germanic, virtually all varieties of German use a construction in which a cognate of the English verb 'do' (standard German 'tun') functions as an auxiliary and selects another verb in the bare infinitive, a construction known as 'do'-periphrasis or 'do'-support. The present paper provides an Optimality Theoretic (OT) analysis of this phenomenon. It builds on a previous analysis by Bader and Schmid (An OT-analysis of 'do'-support in Modern German, 2006) but (i) extends it from root clauses to subordinate clauses and (ii) aims to capture all of the major distributional patterns found across (mostly non-standard) varieties of German. In so doing, the data are used as a testing ground for different models of German clause structure. At first sight, the occurrence of 'do' in subordinate clauses, as found in many varieties, appears to support the standard CP-IP-VP analysis of German. In actual fact, however, the full range of data turn out to challenge, rather than support, this model. Instead, I propose an analysis within the IP-less model by Haider (Deutsche Syntax - generativ. Vorstudien zur Theorie einer projektiven Grammatik, Narr, Tübingen, 1993 et seq.). In sum, the 'do'-support data will be shown to have implications not only for the analysis of clause structure but also for the OT constraints commonly assumed to govern the distribution of 'do', for the theory of non-projecting words (Toivonen in Non-projecting words, Kluwer, Dordrecht, 2003) as well as research on grammaticalization.
Wir diskutieren in diesem Beitrag Implikationen, mit denen man zu tun bekommt, wenn man kleinste Formen situativer Vergesellschaftung – wir sprechen von kommunikativen Minimalformen – untersucht. Kommunikative Minimalformen sind kurzzeitige, nur wenige Sekunden dauernde, gemeinsam konstituierte Interaktionsereignisse. Ungeachtet ihrer Kürze weisen sie zum einen eine komplexe Interaktionsstruktur auf. Zum anderen besitzen sie auch eine klare soziale Implikation und eigene Wertigkeit. In dem hier untersuchten Fall, bei dem Passanten durch ein offenes Fenster in einen Privatraum blicken und dabei ertappt werden, zeigt sich diese soziale Implikativität als moralische Kommunikation im Sinne der interaktiven Bearbeitung eigenen Fehlverhaltens.
