The OWLGrEd ontology editor allows graphical visualization and authoring of OWL 2.0 ontologies using a compact yet intuitive presentation that combines UML class diagram notation with textual Manchester syntax for expressions. For the full use of the graphical ontology tool, it is important to be able to export the ontology in one of OWL textual standards. We describe the OWLGrEd ontology export implementation using patterns that are ascribed to editor diagram abstract syntax elements. The OWLGrEd export patterns show the relationship between editor visual constructions and ontology textual form elements. The pattern-based method allows a tool end-user to define a custom field semantics in OWLGrEd extensions, and it can be generalized also for the model-to-text transformation within other similarly structured tools.

Nowadays open data is entering the mainstream - it is free available for every stakeholder and is often used in business decision-making. It is important to be sure data is trustable and error-free as its quality problems can lead to huge losses. The research discusses how (open) data quality could be assessed. It also covers main points which should be considered developing a data quality management solution. One specific approach is applied to several Latvian open data sets. The research provides a step-by-step open data sets analysis guide and summarizes its results. It is also shown there could exist differences in data quality depending on data supplier (centralized and decentralized data releases) and, unfortunately, trustable data supplier cannot guarantee data quality problems absence. There are also underlined common data quality problems detected not only in Latvian open data but also in open data of 3 European countries.

The aim of effective management of manufacturing processes requires special methods of knowledge management integrated in multi-layered architecture of components of enterprise recourse planning system. Our research work is devoted for extension of knowledge-based management system by integration of specific business management rules for adaptable control of manufacturing processes of woven fabrics. The proposed framework can help for manufacturing process realization of woven fabrics by solving key issues related to rules and data for product design and process planning. This could help knowledge-based system self-learn and change in order to cope with ever-changing business requirements. With this study, we are trying to fill the gap related with knowledge-based methods for effective manufacturing process of woven fabrics.

. Earley parser is a well-known parsing method used to analyse context-free grammars. While being less efficient in practical contexts than other generalized context-free parsing algorithms, such as GLR, it is also more general. As such it can be used as a foundation to build more complex parsing algorithms. We present a new, virtual machine based approach to parsing, heavily based on the original Earley parser. We show how to translate grammars into virtual machine instruction sequences that are then used by the parsing algorithm. Additionally, we introduce an optimization that merges shared rule prefixes to increase parsing performance. Finally, we present and evaluate an implementation of Scannerless Earley Virtual Machine called north .

The paper deals with the spatial relations of containment and support in the Baltic languages in a geometric framework. The geometric framework in our research is based on Region Connection Calculus representing different combinations of two circles depending on primitive topological relation of connectedness and extended with the distance, size, orientation and partial occlusion primitives. The research summarises results of two experiments conducted with 105 Latvian and 106 Lithuanian native speakers, provides the interpretation of 8 support and 5 containment stimuli, and gives a preliminary overview of correlation between different independent variables and the granularity and length of the spatial descriptions. Our results indicate a great variation in interpreting the given stimuli in each language, but the contrastive empirical analysis reveals that heterogeneity of interpretation in both languages is similar. For perception of support and containment relations, axial information and connectedness are the determining primitives.

As a branch of network science, social network analysis widely uses graph techniques. Only in rare cases are results obtained from the graph models validated against “ground truth” and are directly applicable to objects in the investigated domain. Like extraneous solutions in mathematics, ungrounded mechanistic analogies, incorrect interpretation of indirect ties for intransitive relations and use of the “path” concept for social networks may lead to noninvertible results with no evidence outside the used graph model. The author investigates unimodal networks with dyadic ties, provides several examples of correct and incorrect applications and recovers the roots of incorrectness.

Real estate monitoring is very important aspect of country economics, but old manual methods of land survey are time and resources consuming processes as geodata actualization tasks. Actual, precise, multidimensional and detailed information is the main instrument of geospatial intelligence to understand current economic situation and to make effective decision. Actualization of geoinformation using remote sensing is the modern approach of the computer age to complete Earth observation and human environment monitoring. This article describes multi-stage classification model, which detects man-made constructions in LiDAR point cloud. Proposed classification model applies decision tree and geometrical features of shape to remove noises. The goal of study is to experimentally compare decision trees with crisp and fuzzy logic (ID3 algorithms) to select the more suitable algorithm for noise reduction task. Algorithms are compared using total accuracy and Cohen’s Kappa coefficient.

INTRODUCTION Assessing the sustainability of dynamic, open and complex systems with many stakeholders, interrelated components and interactions and forecasting with traditional study methods is complicated and has its limitations. Therefore, often researchers, when forecasting the sustainability of a dynamic system, rely on subjective judgment without references to assessment standards. The aim of the paper is to create an imitation model for the sustainability of a dynamic system in order to assess and forecast the sustainability of the system under alternative development scenarios. It includes 3 main aspects - how sustainable is the dynamic system, what is the level of sustainability of a dynamic system under alternative development scenarios and what additions are needed to improve the functioning of the imitation model. The research question of the paper is: what imitation model can effectively analyse and forecast a dynamic system in the case of the tourism object Cesis Palace. Sustainable development researchers offer to build on traditional principles and interlinked dimensions of sustainable development: environment, economic and social, and adapt them to the dynamic system, which is characterized by the interactions between components (Tanguay et.al., 2011; Mai, Smith, 2018). One type of study that helps explain such systems is simulation modelling, which is often used when researching the interaction of dynamic systems (Johnson, 2011). MATERIALS AND METHODS The Cesis Palace complex as a tourism site was used in the paper for an example of a dynamic system, since tourism is both a dynamic system with many interlinked components and equally important are the three dimensions of sustainability for its long-term development. During the study, multiple data acquisition methods were used: a structured interview, analysis of statistics, case study analysis and an expert interview on the created imitation model. To achieve the goal of the research, a model of a tourism sustainability imitation model was created using the STELLA dynamic system modelling environment. The model and the selection of indicators were based on the three key sustainability dimensions: economy, environment and society/culture. RESULTS The result of the work is a computer model that helps to assess the sustainability of a real-life system and its dimensions by entering data generated during the study. It concludes that the tourism object under consideration is potentially sustainable. Simulating alternative development scenarios, it can be concluded that the elements of one group of indicators can affect both the sustainability level of their own dimension, as well as the indicators of other dimensions and their sustainability level, as well the sustainability of the system overall. Significant changes in the system take place in a situation where a number of indicator groups are affected by the changes. DISCUSION AND CONCLUSIONS In order to use this model
