A number of approaches in traceability link recovery and other software engineering tasks incorporate topic models, such as Latent Dirichlet Allocation (LDA). Although in theory these topic models can produce very good results if they are configured properly, in reality their potential may be undermined by improper calibration of their parameters (e.g., number of topics, hyper-parameters), which could...
Information Retrieval (IR) methods, and in particular topic models, have recently been used to support essential software engineering (SE) tasks, by enabling software textual retrieval and analysis. In all these approaches, topic models have been used on software artifacts in a similar manner as they were used on natural language documents (e.g., using the same settings and parameters) because the...
Coupling is a fundamental property of software systems, and numerous coupling measures have been proposed to support various development and maintenance activities. However, little is known about how developers actually perceive coupling, what mechanisms constitute coupling, and if existing measures align with this perception. In this paper we bridge this gap, by empirically investigating how class...
