Choosing test cases for the optimization process of information systems testing is crucial, because it helps to eliminate unnecessary and redundant testing data. However, its use in systems that address complex domains (e.g. images) is still underexplored. This paper presents a new approach that uses Content-Based Image Retrieval (CBIR), similarity functions and clustering techniques to select ...

While learners’ ability to speak academic language develops over time in content-based programs, the development of their nonacademic language appears to lag behind. Students’ speaking in content-based (CB) classrooms is confined to an academic discourse style. In the researchers’ point of view, the gap of less amount of nonacademic speaking can be bridged by the application of the conceptual f...
