Title / Titel COSA - Software Framework for Content Analysis
PDF Abstract (PDF, 14 KB)
Summary / Zusammenfassung To gather the data for the supply side in the Project "National political change in a globalizing world" (Institute of Political Science, University of Zurich), a new open-source technology, COSA (Core Sentence Annotation), is being developed. It is methodologically based on the flexible content analysis method of "core sentences", which captures the content of a text through a network of relationships between relevant entities (in a newspaper analysis these are, for instance, political actors and issues). The application framework consists, on the one hand, of a pipeline which imports and selects newspaper articles from common databases. On the other hand, additional software components extract metadata and detect relevant entities. Further development steps comprise the implementation of a database and coding clients for multiple users. The software tool can be adapted to accomplish different research challenges for content analysis.

COSA (in particular, its language processing module) is developed in collaboration with Alexandra Bünzli and Simon Clematide of the Intitute of Computational Linguistics.
