REFOCUS: Current & Future Search Interface Requirements for German-speaking Users

When looking at current research, there is plenty of existing work inquiring into how users use search engines1 and how future search interfaces could look like2. Yet, an investigation of users' perceptions of and expectations towards current and future search interfaces is still missing. Therefore, at this year's International Conference on WWW/Internet (ICWI '16) my co-author Martin Gaedke… Continue reading REFOCUS: Current & Future Search Interface Requirements for German-speaking Users

Usability-based Split Testing or How to infer web interface usability from user interactions

The continuous evaluation of an e-commerce company's web applications is crucial for ensuring customer satisfaction and loyalty. Such evaluations are usually performed as split tests, i.e., the comparison of two slightly different versions of the same webpage with respect to a target metric. Usually, metrics that stakeholders are interested in include completed checkout processes, submitted… Continue reading Usability-based Split Testing or How to infer web interface usability from user interactions

StreamMyRelevance! Predicting Search Result Relevance from Streams of Interactions
