Title : Automatic Thematic Content Analysis: Finding Frames in News

Presenter Daan Odijk
Abstract In this talk I’ll be presenting our work that received the best paper award at the Social Informatics conference, a few months ago. The purpose of my talk is to receive feedback on this work and brainstorm about ideas for future work. Framing in news is the way in which journalists depict an issue in terms of a ‘central organizing idea.’ Frames can be a perspective on an issue. We explore the automatic classification of four generic news frames: conflict, human interest, economic consequences, and morality. Complex characteristics of messages such as frames have been studied using thematic content analysis. Indicator questions are formulated, which are then manually coded by humans after reading a text and combined into a characterization of the message. We operationalize this as a classification task and, inspired by the way-of-working of media analysts, we propose a two-stage approach, where we first rate a news article using indicator questions for a frame and then use the outcomes to predict whether a frame is present. We approach human accuracy on almost all indicator questions and frames. http://daan.odijk.me/post/60076455223/finding-frames-in-news

Title : Enabling Provenance-based Trust Assessment by Exposing Provenance of Content on the Web

Presenter Tom De Nies
Abstract In this presentation, I will give a brief overview of my research, with special focus on the assessment of trustworthiness of content on the Web. As is to be expected, provenance is an essential element in my proposed approach. However, for most Web resources, there is little to no provenance available, or at least not in a standard form. Therefore, I propose two ways to obtain this provenance: through reconstruction of missing provenance, and through mapping of non-standardized provenance. I'll conclude with a number of examples of experiments I've performed for these aspects of my research.
