Context: A key issue when dealing with the generalization threat of software engineering experiments is to use different subject types. Objective: In this paper, we aim to investigate which subject types are used in experiments and their impact on results. Method: We have performed a systematic mapping study by manually searching experiments published from January 2014 to June 2016 in six leading...
Knowledge plays a central role in intelligent systems. Manual knowledge acquisition is very inefficient and expensive. In this paper, we present (1) an automatic method to acquire a large amount of lexical-dependency knowledge, and (2) an innovative knowledge representation model to effectively minimize the impact of noise and improve knowledge quality. We also propose a new type of knowledge base...
Detecting design patterns from object-oriented program source-code can help maintainers understand the design of the program. However, the detection precision of conventional approaches based on the structural aspects of patterns is low due to the fact that there are several patterns with the same structure. To solve this problem, we propose an approach of design pattern detection using source-code...
