- Abstract
- Eine der wesentlichen Aufgaben als Fachreferent*in ist die inhaltliche Erschließung der neuerworbenen Literatur, sowie die Begutachtung und Auswahl der neu erschienenen Werke in den jeweiligen Fachgebieten hinsichtlich der Relevanz für die eigenen Sammlungen gemäß dem Sammlungsprofil der TU Wien Bibliothek. Im Zuge der Corona-Krise wurde die herkömmliche Arbeitsweise in der Sacherschließung beeinträchtigt, und es haben sich neue Herausforderungen, aber auch Möglichkeiten ergeben. Neben der fehlenden Autopsie der Literatur leidet auch die Sichtung und Erwerbung neuer Literatur unter der physischen Abwesenheit vom Arbeitsplatz bzw. der entsprechenden technischen Infrastruktur. Auch der persönliche Austausch mit den Kolleg*innen wurde deutlich erschwert. Neben den Schwierigkeiten wurden aber auch die neuen Handlungsoptionen auf beruflicher und individueller Ebene positiv gesehen. In dem Artikel werden unsere individuellen Erfahrungen an der TU Wien Bibliothek sowie Ausblicke in die Zukunft wiedergegeben.

- Abstract
- On a scientific concept hierarchy, a parent concept may have a few attributes, each of which has multiple values being a group of child concepts. We call these attributes facets: classification has a few facets such as application (e.g., face recognition), model (e.g., svm, knn), and metric (e.g., precision). In this work, we aim at building faceted concept hierarchies from scientific literature. Hierarchy construction methods heavily rely on hypernym detection, however, the faceted relations are parent-to-child links but the hypernym relation is a multi-hop, i.e., ancestor-to-descendent link with a specific facet "type-of". We use information extraction techniques to find synonyms, sibling concepts, and ancestor-descendent relations from a data science corpus. And we propose a hierarchy growth algorithm to infer the parent-child links from the three types of relationships. It resolves conflicts by maintaining the acyclic structure of a hierarchy.

- Abstract
- Converting UDC numbers manually to a complex format such as the one mentioned above is an unrealistic expectation; supporting building these representations, as far as possible automatically, is a well-founded requirement. An additional advantage of this approach is that the existing records could also be processed and converted. In my dissertation I would like to prove also that it is possible to design and implement an algorithm that is able to convert pre-coordinated UDC numbers into the introduced format by identifying all their elements and revealing their whole syntactic structure as well. In my dissertation I will discuss a feasible way of building a UDC-specific XML schema for describing the most detailed and complicated UDC numbers (containing not only the common auxiliary signs and numbers, but also the different types of special auxiliaries). The schema definition is available online at: http://piros.udc-interpreter.hu#xsd. The primary goal of my research is to prove that it is possible to support building, retrieving, and analyzing UDC numbers without compromises, by taking the whole syntactic richness of the scheme by storing the UDC numbers reserving the meaning of pre-coordination. The research has also included the implementation of a software that parses UDC classmarks attended to prove that such solution can be applied automatically without any additional effort or even retrospectively on existing collections.

- Abstract
- The successes of information retrieval (IR) in recent decades were built upon bag-of-words representations. Effective as it is, bag-of-words is only a shallow text understanding; there is a limited amount of information for document ranking in the word space. This dissertation goes beyond words and builds knowledge based text representations, which embed the external and carefully curated information from knowledge bases, and provide richer and structured evidence for more advanced information retrieval systems. This thesis research first builds query representations with entities associated with the query. Entities' descriptions are used by query expansion techniques that enrich the query with explanation terms. Then we present a general framework that represents a query with entities that appear in the query, are retrieved by the query, or frequently show up in the top retrieved documents. A latent space model is developed to jointly learn the connections from query to entities and the ranking of documents, modeling the external evidence from knowledge bases and internal ranking features cooperatively. To further improve the quality of relevant entities, a defining factor of our query representations, we introduce learning to rank to entity search and retrieve better entities from knowledge bases. In the document representation part, this thesis research also moves one step forward with a bag-of-entities model, in which documents are represented by their automatic entity annotations, and the ranking is performed in the entity space.
This proposal includes plans to improve the quality of relevant entities with a co-learning framework that learns from both entity labels and document labels. We also plan to develop a hybrid ranking system that combines word based and entity based representations together with their uncertainties considered. At last, we plan to enrich the text representations with connections between entities. We propose several ways to infer entity graph representations for texts, and to rank documents using their structure representations. This dissertation overcomes the limitation of word based representations with external and carefully curated information from knowledge bases. We believe this thesis research is a solid start towards the new generation of intelligent, semantic, and structured information retrieval.

- Abstract
- While classifications are heavily used to categorize web content, the evolution of the web foresees a more formal structure - ontology - which can serve this purpose. Ontologies are core artifacts of the Semantic Web which enable machines to use inference rules to conduct automated reasoning on data. Lightweight ontologies bridge the gap between classifications and ontologies. A lightweight ontology (LO) is an ontology representing a backbone taxonomy where the concept of the child node is more specific than the concept of the parent node. Formal lightweight ontologies can be generated from their informal ones. The key applications of formal lightweight ontologies are document classification, semantic search, and data integration. However, these applications suffer from the following problems: the disambiguation accuracy of the state of the art NLP tools used in generating formal lightweight ontologies from their informal ones; the lack of background knowledge needed for the formal lightweight ontologies; and the limitation of ontology reuse. In this dissertation, we propose a novel solution to these problems in formal lightweight ontologies; namely, faceted lightweight ontology (FLO). FLO is a lightweight ontology in which terms, present in each node label, and their concepts, are available in the background knowledge (BK), which is organized as a set of facets. A facet can be defined as a distinctive property of the groups of concepts that can help in differentiating one group from another. Background knowledge can be defined as a subset of a knowledge base, such as WordNet, and often represents a specific domain.

- Abstract
- In this thesis we propose three new word association measures for multi-word term extraction. We combine these association measures with LocalMaxs algorithm in our extraction model and compare the results of different multi-word term extraction methods. Our approach is language and domain independent and requires no training data. It can be applied to such tasks as text summarization, information retrieval, and document classification. We further explore the potential of using multi-word terms as an effective representation for general web-page summarization. We extract multi-word terms from human written summaries in a large collection of web-pages, and generate the summaries by aligning document words with these multi-word terms. Our system applies machine translation technology to learn the aligning process from a training set and focuses on selecting high quality multi-word terms from human written summaries to generate suitable results for web-page summarization.

- Abstract
- Die IT-Industrie hat die Bildung als Geschäftsfeld seit vielen Jahren auf der Agenda. Wirtschaftsverbände und IT-Vertreter fordern unisono, Digitaltechnik und Programmiersprachen schon in der Grundschule zu unterrichten, damit die Schülerinnen und Schüler für die digitale Zukunft gerüstet seien. Dabei ist der Nutzen digitaler Medien im Unterricht nach wie vor fragwürdig. Ralf Lankau entlarvt in diesem Buch die wirtschaftlichen Interessen der IT-Branche und ihrer Lobbyisten. Dabei geht er sowohl auf die wissenschaftlichen Grundlagen (Kybernetik, Behaviorismus) als auch auf die technischen Rahmenbedingungen von Netzen und Cloud-Computing ein, bevor er konkrete Vorschläge für einen reflektierten und verantwortungsvollen Umgang mit Digitaltechnik im Unterricht skizziert. Die These des Autors lautet: Wir müssen uns auf unsere pädagogische Aufgabe besinnen und (digitale) Medien wieder zu dem machen, was sie im strukturierten Präsenzunterricht sind: didaktische Hilfsmittel.

- Abstract
- Wissen ist die zentrale Ressource von Unternehmen, welche Mitarbeiter benötigen, um innovative Produkte und Dienstleistungen entwickeln zu können. Dokumentiertes Wissen, wie Patente, Strategiemodelle, Best Practices oder Benchmark-Beschreibungen, lässt sich effizient in digitaler Form speichern und über digitale Netze austauschen. Derartige Wissenswerte können so innerhalb und zwischen Unternehmen über elektronische Märkte gehandelt werden. Wolfgang Maass entwickelt das Konzept eines digitalen Wissensgutes, integriert es in ein Referenzmodell für elektronische Wissensmärkte und stellt technische Umsetzungsmöglichkeiten vor.

- Abstract
- Das von der DFG geförderte Projekt LibRank erforscht neue Rankingverfahren für bibliothekarische Informationssysteme, die aufbauend auf Erkenntnissen aus dem Bereich Websuche qualitätsinduzierende Faktoren wie z. B. Aktualität, Popularität und Verfügbarkeit von einzelnen Medien berücksichtigen. Die konzipierten Verfahren werden im Kontext eines in den Wirtschaftswissenschaften häufig genutzten Rechercheportals (EconBiz) entwickelt und in einem Testsystem systematisch evaluiert. Es werden Rankingfaktoren, die für den Bibliotheksbereich von besonderem Interesse sind, vorgestellt und exemplarisch Probleme und Herausforderungen aufgezeigt.

- Abstract
- In seinem Kultbuch Eine kurze Geschichte der Menschheit erklärte Yuval Noah Harari, wie unsere Spezies die Erde erobern konnte. In "Homo Deus" stößt er vor in eine noch verborgene Welt: die Zukunft. Was wird mit uns und unserem Planeten passieren, wenn die neuen Technologien dem Menschen gottgleiche Fähigkeiten verleihen - schöpferische wie zerstörerische - und das Leben selbst auf eine völlig neue Stufe der Evolution heben? Wie wird es dem Homo Sapiens ergehen, wenn er einen technikverstärkten Homo Deus erschafft, der sich vom heutigen Menschen deutlicher unterscheidet als dieser vom Neandertaler? Was bleibt von uns und der modernen Religion des Humanismus, wenn wir Maschinen konstruieren, die alles besser können als wir? In unserer Gier nach Gesundheit, Glück und Macht könnten wir uns ganz allmählich so weit verändern, bis wir schließlich keine Menschen mehr sind.

- Rez. in Mitt. VÖB 63(2010) H.1/2, S.148-149 (M. Buzinkay): "Endlich wieder ein Buchtitel, der mich nicht nur gleich angesprochen, sondern auch das gehalten, was er versprochen hat. Eine vertiefende Lektüre in ein sehr aktuelles und sehr wichtiges Thema, dass sowohl Einzelpersonen wie auch Organisationen, Unternehmen und Vereine gleichermaßen beschäftigen muss: "Wie Social Media Wirtschaft und Gesellschaft verändern" heißt der Untertitel des Werkes von Erik Qualman. Der Autor liefert für seine Behauptungen ausgesuchte Beispiele, diese seine Argumentation untermauern. Schön ist, dass man diese Beispiele gleich als Hands-on Tipps für seine eigene Online Arbeit nutzen kann. Bei der schier unendlichen Anzahl von Beispielen muss man sich aber fragen, ob man je in der Lage sein wird, diese nützlichen Hinweise jemals nur annähernd im eigenen Unternehmen umzusetzen. Um es kurz zu fassen: man kann das Buch mit ins Bett nehmen und in einem durchlesen. Fad wird einem nicht, nur genug Post-its sollte man mitnehmen, um alles wichtige zu markieren und zu notieren. Am nächsten Morgen sollte man das Buch aber sein lassen, denn das Geheimnis von Socialnomics ist die Umsetzung im Web. Eine dringende Empfehlung an alle Marketing-Interessierten!"
