    • An approach for allocation of shared resources in the rule-based business process simulation 

      Rusinaitė, Toma; Vasilecas, Olegas; Savickas, Titas; Vysockis, Tadas; Normantas, Kęstutis (CompSysTech '16 : proceedings of the 17th international conference on Computer Systems and Technologies 2016, Palermo, Italy, June 23-24, 2016, 2016)
      Simulation is an important business process (BP) analysis technique that allows modelling various process execution scenarios under different circumstances. One of the key factors that influence process execution is the ...

    • An overview of the knowledge discovery meta-model 

      Normantas, Kęstutis; Sosunovas, Sergejus; Vasilecas, Olegas (CompSysTech'12 : proceedings of the 13th international conference on Computer Systems and Technologies, Ruse, Bulgaria, June 22 - 23, 2012, 2012)
      Modernization of existing software systems is expensive and not always successive process that involves many challenging activities. In order to support these activities, the Object Management Group within the Architecture-Driven ...

    • Bayesian belief network application in process mining 

      Savickas, Titas; Vasilecas, Olegas (CompSysTech'14 : Proceedings of the 15th international conference on computer cystems and technologies, Ruse, Bulgaria, June 27, 2014, 2014)
      Business process mining gains more and more attention from both scientific and business communities. Its value has been recognized in information systems reverse engineering field as it allows discover knowledge about the ...

    • Evaluating the method of the transforming ontology axioms to application domain rules 

      Kalibatienė, Diana; Vasilecas, Olegas (Proceedings of the International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing "CompSysTech'09", Ruse, Bulgaria, 18-19 June 2009, 2009)
      Application domain knowledge presented by ontology is used mainly for conceptual modelling of information systems in the information systems development context. A number of methods are suggested for mapping of an ontology ...

    • Formal concept analysis and information systems modeling 

      Laukaitis, Algirdas; Vasilecas, Olegas (Proceedings of the International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing "CompSysTech'07", Rousse, Bulgaria, 14-15 June 2007, 2007)
      In this paper, we present the methodology based on formal concept analysis (FCA) for the information system model verification. We show that FCA can be useful for understanding conceptual model topology and it can be used ...

    • Monitoring of statistical data on GHG emissions using GIS: A review 

      Metrikaitytė-Gudelė, Gustė; Sužiedelytė Visockienė, Jūratė (ICGDA 2023 2023 6th International Conference on Geoinformatics and Data Analysis, April 13 -15, 2023 Marseille, France, 2023)
      The aim of this work is to analyse greenhouse gases (GHGs), their emissions in the agricultural sector, and the possibility of monitoring them through remote sensing (RS), and data-driven solutions. In this paper using GIS ...

    • Resource modelling for the rule- and context-based dynamic business process simulation 

      Kalibatienė, Diana; Vasilecas, Olegas; Bobrovs, Vjačeslavs (CompSysTech '16 : proceedings of the 17th international conference on Computer Systems and Technologies 2016, Palermo, Italy, June 23-24, 2016, 2016)
      Resource definition and allocation is a crucial task for improvement of a business process (BP) performance. Although some methods and recommendations have been proposed to resource models and resource allocation, there ...

    • Towards web-scale structured web data extraction 

      Grigalis, Tomas (Web Search and Data Mining (WSDM'13) : proceedings of the sixth ACM international conference, 2013)
      In this paper we present an ongoing PhD research on unsupervised and domain-independent structured data extraction from the Web. We propose a novel method to extract structured data records from template-generated Web ...
