SMOTL—A System to Construct Samples for Data Processing Program Debugging

The possibility of automatic construction of a complete set of program tests is considered. A test set system is said to be complete if every feasible program branch (segment) is executed by it. The complete test set construction algorithm for commercially oriented data processing programs is outlined, and the results of its functioning on real programs are analyzed.

Automatic Construction of Test Sets: Practical Approach

The problem of symbolic execution and test generation is considered both for sequential and concurrent programs. Practical methods for test construction for the given program path are presented.

A Light Insight into Latvian and Lithuanian ICT Terminology: Whether Kindred Language Imply Kindred Terminology?

Lithuanian and Latvian are two closely related languages, the only two of the Baltic branch of Indo-European languages. They are quite similar and share a great deal of vocabulary and grammar features, but not close enough to make conversation possible. The paper reveals that commonalities between Latvian and Lithuanian information and communication technologies (ICT) terms are mostly due internationalisms, there are only small proportion of terms with common Baltic word-roots; influence of English language in Latvian and Lithuanian ICT terminology is moderate, if not minor; deliberately or unawares, Lithuanian terminologists follow the same rules as their Latvian counterparts.

An Approach for iOS Applications' Testing

The mobile conquers the world. The need in a comprehensive and systemized multiedge testing approach is rising along with mobile apps becoming even more complex. As a leader in enterprise market, Apple iOS has been chosen as a target mobile platform for the study. The authors have investigated aspects that influence functional testing of iOS apps in particular, and mobile – in general. The study also exposes the security capabilities and risks that often are not mitigated in favor of time to market rush. Investigation and clustering of mobile UI test automation tools is performed. The capabilities and limitations of Apple UIAutomation are discovered. Solutions aimed at overcoming the limitations of out of the box UIAutomation are united in tTap framework developed by the authors. In conclusion an ideal cross-platform mobile UI test automation tool is proposed.

Can SQ and EQ Values and Their Difference Indicate Programming Aptitude to Reduce Dropout Rate

A crucial problem that we are currently facing at the Faculty of Computing of the University of Latvia is that during the first study semester on average 30% of the first-year students drop out, whereas after the first year of studies the number of dropouts increases up to nearly 50%. Thus, our overall goal is to determine in advance applicants that most likely will not finish the first study year successfully. A hypothesis formulated in another research study was that programming aptitude could be predicted based on the results of two personality self-report questionnaires − Systemizing Quotient (SQ) and Empathy Quotient (EQ) − taken by students. The difference between the SQ and EQ scores had a strong correlation with grades received for programming test. We reproduced the circumstances of mentioned empirical study with our first-year students using similar tests to calculate SQ and EQ, and semester grades in introductory programming course as a quantitative measure to evaluate programming ability. In this paper, we elaborate on the empirical setting, measures, and estimation methods of our study, which produced the results that made us call the stated hypothesis into question and disprove it.

Databases and Information Systems

Ontologies are one of the core foundations of the Semantic Web. To participate in Semantic Web projects, domain experts need to be able to understand the ontologies involved. Visual notations can provide an overview of the ontology and help users to understand the connections among entities. However, the users first need to learn the visual notation before they can interpret it correctly. Controlled natural language representation would be readable right away and might be preferred in case of complex axioms, however, the structure of the ontology would remain less apparent. We propose to combine ontology visualizations with contextual ontology verbalizations of selected ontology (diagram) elements, displaying controlled natural language (CNL) explanations of OWL axioms corresponding to the selected visual notation elements. Thus, the domain experts will benefit from both the high-level overview provided by the graphical notation and the detailed textual explanations of particular elements in the diagram.

Heuristic Method to Improve Systematic Collection of Terminology

In this paper, we propose an experimental tool for analysis and graphical representation of glossaries. The original heuristic algorithms and analysis methods incorporated into the tool appeared to be useful to improve the quality of the glossaries. The tool was used for analysis of ISTQB Standard Glossary of Terms Used in Software Testing. There are instances of problems found in ISTQB glossary related to its consistency, completeness, and correctness described in the paper.

Research Directions Profile in the Computing Museum of the Institute of Mathematics and Computer Science, University of Latvia (IMCS)

The article describes the development of information technology in Latvia, in IMCS, to the middle of the 1990s. The history of IMCS represents the usage of computers in typical computing centers in the former Soviet Union and the transformation from computing center to research institution. It also represents Latvian collaboration with the Nordic countries that provided political, scientific, and technological support. Historical documents, computer parts, and photos are collected in the Computer Museum of IMCS.

An Approach to Cadastral Map Quality Evaluation in the Republic of Latvia

An approach to cadastral map quality evaluation is proposed, which is elaborated and implemented by State Land Service of the Republic of Latvia. The approach is based on opinion of Land Service experts about cadastral map quality that depends on its usage points. Quality parameters of cadastral map objects identified by experts and its limit values are used for evaluation. The assessment matrix is used, which allow to define cadastral map quality that depends on its usage purpose. The matrix is used to find out, of what quality a cadastral map should be in order to be used for the chosen purpose. The given approach is flexible, it gives a possibility to change sets of quality parameters and their limit values as well as to use the approach for other type data quality evaluation.
