Straipsnis skirtas duomenų tyrybos, pagrįstos saityno paslaugomis, analizei. Apibrėžiamos pagrindinės su saityno paslaugomis susijusios sąvokos. Pristatomos paskirstytosios duomenų tyrybos galimybės bei jų įgyvendinimo priemonės – Grid, Hadoop. Atliekama duomenų tyrybos sistemų, pagrįstų saityno paslaugomis, analitinė apžvalga. Parenkami sistemų palyginimo kriterijai. Pagal šiuos kriterijus atliekama populiariausių duomenų tyrybos sistemų, pagrįstų saityno paslaugomis, lyginamoji analizė. Nustatoma, kurios sistemos įvertinamos geriausiai, o kurios neatitinka daugumos kriterijų.Data mining systems, based on Web services Olga Kurasova, Virginijus Marcinkevičius, Viktor Medvedev, Aurimas Rapečka
SummaryIn the paper, data mining systems, based on web services, are analysed. The main notation related with web services is described. The possibilities of distributed data mining and their implementation tools – Grid, Hadoop are introduced. An analytical review of the data mining systems, based on web services, is provided. Some comparison criteria are selected. According to the criteria, a comparative analysis of the popular data mining systems, based on web services, is made. The paper illustrates, which systems are best for evaluating and which do not satisfy most of the criteria.11pt; line-height: 115%; font-family: Calibri, sans-serif;">

The growing number of COVID-19 cases puts pressure on healthcare services and public institutions worldwide. The pandemic has brought much uncertainty to the global economy and the situation in general. Forecasting methods and modeling techniques are important tools for governments to manage critical situations caused by pandemics, which have negative impact on public health. The main purpose of this study is to obtain short-term forecasts of disease epidemiology that could be useful for policymakers and public institutions to make necessary short-term decisions. To evaluate the effectiveness of the proposed attention-based method combining certain data mining algorithms and the classical ARIMA model for short-term forecasts, data on the spread of the COVID-19 virus in Lithuania is used, the forecasts of epidemic dynamics were examined, and the results were presented in the study. Nevertheless, the approach presented might be applied to any country and other pandemic situations. The COVID-19 outbreak started at different times in different countries, hence some countries have a longer history of the disease with more historical data than others. The paper proposes a novel approach to data registration and machine learning-based analysis using data from attention-based countries for forecast validation to predict trends of the spread of COVID-19 and assess risks.
