Research in Business Information Systems includes empirical as well as design related activities. For gaining access to domain knowledge for building an Information System, we have developed a method guiding researchers from qualitative, empirical research to the identification of requirements for Software features. The method builds on expert interviews, communicative validation, concept mappi...

We present the MOLTKE workbench for technical diagnosis, a fully implemented knowledge acquisition environment which has been tested on several real world applications (e.g. fault diagnosis of CNC machining centers). MOLTKE combines different techniques of second generation expert systems (qualitative, case-based, inductive reasoning). Thus, it is able, to process knowledge from the three main ...

Nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. Copper oxide nano materials are of interest on account of their potential uses in many technological fields. In this study  CuO nanoparticles were synthesized via simple sol gel method using basic CuSO4<...

insurance industry experts believe that fraud is a destructive disaster in the insurance industry. over the years, many methods have been used in the literature for fraud detection, one of which is expert systems. fraud detection expert systems are based on the knowledge of experts in the field of insurance identify fraud. judgment of experts is mostly based on evidence, documents, qualitative ...

Purpose – A good recommender system helps users find items of interest on the web and can provide recommendations based on user preferences. In contrast to automatic technology-generated recommender systems, this paper aims to use dynamic expert groups that are automatically formed to recommend domain-specific documents for general users. In addition, it aims to test several effectiveness measu...

in this paper, we present the step by step knowledge acquisition process by choosing a structured method through using a questionnaire as a knowledge acquisition tool. Here we want to depict the problem domain as, “how to evaluate teacher’s performance in higher education through the use of expert system technology”. The problem is how to acquire the specific knowledge for a selected problem ef...
