We present SentText, a web-based tool to perform and explore lexicon-based sentiment analysis on texts, specifically developed for the Digital Humanities (DH) community. The tool was developed integrating ideas of the user-centered design process and we gathered requirements via semi-structured interviews. The tool offers the functionality to perform sentiment analysis with predefined sentiment lexicons or self-adjusted lexicons. Users can explore results of sentiment analysis via various visualizations like bar or pie charts and word clouds. It is also possible to analyze and compare collections of documents. Furthermore, we have added a close reading function enabling researchers to examine the applicability of sentiment lexicons for specific text sorts. We report upon the first usability tests with positive results. We argue that the tool is beneficial to explore lexicon-based sentiment analysis in the DH but can also be integrated in DHteaching.

No existing evaluation infrastructure for shared tasks currently supports both reproducible onand offline experiments. In this work, we present an architecture that ties together both types of experiments with a focus on reproducibility. The readers are provided with a technical description of the infrastructure and details of how to contribute their own experiments to upcoming evaluation tasks.

This paper examines the educational datasets of Open Government Portals (OGPs) in Germany. While OGPs has become an important player in making public data available, the quality and coverage are increasingly problematized. This study analyzes the quality of 28 OGPs, 18 on the city-level, seven on the state-level (the city-states of Berlin, Hamburg, and Bremen were counted as states), and three at the national level. The focus of this study is on identifying the gap in open educational data. The results show that the total number of datasets and the educational data varies very much between the portals. While the portals contain 94% ‘open’ datasets, most of the portals do not provide comprehensive usage metrics like the data download, evidence of usage in research or applications. Finally, the paper highlights the main shortcomings of the existing open data portals regarding the quality of datasets and the lack of findability and granularity.

In this paper, we present a survey study with 119 participants conducted in German, which investigates respondents’ Facebook behavior. In particular, the survey provides insight into how the individual factors gender, user type and trust in social media influence information behavior with respect to false information on Facebook. Our participants’ Facebook use is predominantly passive, the trust in social media is mediocre and most users claim to encounter false information on a weekly basis. If the truthfulness of information is verified it is mostly done by checking alternative sources and for the most part, users do not react actively to false information on Facebook. Of the different categories of Facebook users studied, more active and intensive users of Facebook (posters and heavy users) encounter false information the most. These users are the only user group to report posts with false information to Facebook or interact with the post. Participants with higher trust in social media tend to check the comments of a post to verify information.

Open Educational Resources (OER) werden durch ihre offene Lizenzierung und den damit verbundenen Möglichkeiten zur Nachnutzung Potenziale zur Verbesserung von Lern-/Lehrsituationen zugeschrieben. In unserer Mixed-MethodsStudie erheben wir die Einschätzung zum Nutzen von OER für die Lehrpraxis von Lehrenden der deutschsprachigen Informationswissenschaft. Außerdem fragen wir nach Umsetzungsmöglichkeiten eines gemeinsamen OER-Pools und den Einstellungen zu gemeinschaftlichen Erstellungsprozessen von Lern-/Lehrmaterial. Im folgenden Posterbeitrag werden erste Ergebnisse einer qualitativen Befragung ausgewählter Lehrender vorgestellt, die Basis für eine darauf aufbauende quantitative Befragung unter Lehrenden der deutschsprachigen Informationswissenschaft ist.
