"Data Analysis" in the broadest sense is the general term for a field of activities of ever-increasing importance in a time called the information age. It covers new areas with such trendy labels as, e.g., data mining or web mining as well as traditional directions emphazising, e.g., classification or knowledge organization. Leading researchers in data analysis have contributed to this volume and delivered papers on aspects ranging from scientific modeling to practical application. They have devoted their latest contributions to a book edited to honor a colleague and friend, Hans-Hermann Bock, who has been active in this field for nearly thirty years

"Two developments in computational text analysis may change the way qualitative data analysis in social sciences is performed: 1. the availability of digital text worth to investigate is growing rapidly, and 2. the improvement of algorithmic information extraction approaches, also called text mining, allows for further bridging the gap between qualitative and quantitative text analysis. The key factor hereby is the inclusion of context into computational linguistic models which extends conventional computational content analysis towards the extraction of meaning. To clarify methodological differences of various computer-assisted text analysis approaches the article suggests a typology from the perspective of a qualitative researcher. This typology shows compatibilities between manual qualitative data analysis methods and computational, rather quantitative approaches for large scale mixed method text analysis designs."

With the rapid development of computer science and the expanding use of computers in all facets of American life, there has been made available a wide range of instructional and informational films on automation, data processing, and computer science. Here is the first annotated bibliography of these and related films, gathered from industrial, institutional, and other sources.This bibliography annotates 244 films, alphabetically arranged by title, with a detailed subject index. Information is also provided concerning the intended audience, rental-purchase data, ordering procedures, and such s

"Zwei jüngere Entwicklungen in der computergestützten Textanalyse bieten großes Veränderungspotenzial für die sozialwissenschaftliche Analyse qualitativer Daten: Erstens nimmt die Verfügbarkeit von digitalem Textmaterial rasant zu, und zweitens tragen Verbesserungen in den Verfahren algorithmischer Informationsextraktion, auch Text Mining genannt, dazu bei, die Spaltung zwischen qualitativen und quantitativen Textanalysen zu überwinden. Der entscheidende Fortschritt im Gegensatz zur computergestützten quantitativen Inhaltsanalyse besteht darin, dass neuere computerlinguistische Modelle Kontextinformationen in ihre Analysen einbeziehen. Ihre Kapazitäten erweitern sich so von der Auszählung von Begriffshäufigkeiten hin zur Extraktion von Bedeutung. Der Artikel stellt verschiedene Ansätze computergestützter Textanalysen vor und führt eine Typologie aus der Sicht qualitativer Sozialforschung ein, um methodologische Unterschiede zu verdeutlichen. Diese Typologie zeigt: Je besser die algorithmischen Verfahren in der Lage sind, komplexere semantische Strukturen über die Ebene einzelner Worte hinaus zu identifizieren, umso produktiver können sie mit manuellen Ansätzen qualitativer Datenanalyse in einem Mixed-Method-Forschungsdesign zur Analyse sehr großer Textmengen integriert werden."
