Requirements acquisition is widely recognized as a hard problem, requiring significant investments in time and effort. Given the availability of large volumes of data and of relatively cheap instrumentation for data acquisition, this paper explores the prospect of data-driven model extraction in the context of i* models. The paper presents techniques for extracting dependencies from message log...

To acquire one's native phonological system, language-specific phonological categories and relationships must be extracted from the input. The acquisition of the categories and relationships have each in their own right been the focus of intense research. However, it is remarkable that research on the acquisition of categories and the relations between them has proceeded, for the most part, ind...

Load Frequency Control (LFC) has received considerable attention during last decades. This paper proposes a new method for designing decentralized interaction estimators for interconnected large-scale systems and utilizes it to multi-area power systems. For each local area, a local estimator is designed to estimate the interactions of this area using only the local output measurements. In fact,...

In the last decades, numerous developments and legal changes moved the utility industry towards a liberalized market. Utility enterprises have to stay competitive and reduce costs while managing more complex IT systems. The authors of this work see special demand for aligning business and IT for small and medium-sized enterprises (SME) in this industry and identify the development of a referenc...

This meta-analysis investigated whether animation is beneficial overall for learning compared to static graphics, while also identifying moderator factors affecting the global effect. A systematic search was conducted for experimental studies comparing the impact of animated vs. static graphics displays in the context of knowledge acquisition. A total of 50 papers were considered, and consecuti...

Acquiring knowledge from experts has been a challenge within several research fields. There is no difference in the scope of Biomedicine, mainly because of the large amount of data. In this paper, we present an underway research being conducted in the domain of hematology, which investigates problems of the knowledge acquisition activity. A list of topics to carry out the knowledge acquisition ...

Knowledge workers often deal with multiple sources of data when acquiring information for decision making. Multiple data sources are valuable for knowledge creation, but deciding how to integrate and analyze these different data sources is difficult. The data acquisition process and the task of correctly combining and manipulating data these data in the “information supply chain” have challenge...
