Sidestepping the IT Artifact, Scrapping the IS Silo, and Laying Claim to "Systems in Organizations"

Steven Alter
2003 Communications of the Association for Information Systems  
This paper starts by examining the meaning of "IT artifact" and concluding that this term is too unclear to serve as a basic concept for delineating the field.  ...  The "IT artifact" and debates about the core of the IS field received a lot of attention in the last several years.  ...  IT artifact example: The inconsistency was an artifact of the coding scheme used in the previous information system.  ...

Evaluation of the Ontological Knowledge Model/ Ontoloģiskā zināšanu modeļa novērtēšana/ Оценка качества онтологической модели знаний

Darya Plinere, Arkady Borisov
2014 Information Technology and Management Science  
The common ontology is used for agent cooperation; the quality of ontology is measured with ontology evaluation techniques.  ...  An ontology is an explicit formal conceptualization of some domain of interest. Ontology application is widely used in multi-agent systems.  ...  The overlap between the domain-specific terms and the terms appearing in ontology used to measure lexical keyword coverage by ontology labels. We used the precision and recall method.  ...

Which Variables Should I Log?

Zhongxin Liu, Xin Xia, David Lo, Zhenchang Xing, Ahmed E. Hassan, Shanping Li
2019 IEEE Transactions on Software Engineering  
Developers usually depend on inserting logging statements into the source code to collect system runtime information. Such logged information is valuable for software maintenance.  ...  However, due to the lack of rigorous logging guidance and the requirement of domain-specific knowledge, it is not easy for developers to make proper decisions about which variables to log.  ...  For each project, first, we download its source code from its official website or git repository and extract all the Java methods from the source code using the Eclipse Java development tools (JDT) [39  ...
