The development of Internet resulted in an increasing number of online text re-positories. In many cases, documents are assigned to more than one class and automatic multi-label classification needs to be used. When the number of labels exceeds the number of the documents, effective label space dimension reduction may signifi-cantly improve classification accuracy, what is a major priority in the medical field. In the paper, we propose document clustering for label selection. We use semi-clustering method, by considering graph representation, where documents are represented by vertices and edge weights are calculated according to their mutual similarity. Assigning documents to semi-clusters helps in reducing number of labels, further used in multilabel classification process. The performance of the method is examined by experiments conducted on real medical datasets.

The aim of this work is to study the structure of information and telecommunications technologies (ICT) usage in Polish enterprises in 2015. In this paper the overrepresentation maps were considered as a tool of data mining. These maps are crated as the results of GCA algorithm. The analysis of data about ICT in Polish enterprises were shown as an example of GCA application. The advantage of the method is the visualization possibility and legibility of the obtained maps. In this ar-ticle we studied the level of usage of ICT in individual voivodeships, the expenditures for various sectors of ICT for small, medium-size and big enterprises.

After the introduction of the Energy Law in 1997, many enterprises started to operate in the power industry, which is translated into the electricity prices competitiveness. The further household tariff extension with more expensive rates at peak times, and favorable lower rates during the night and off-peak hours, did not result significantly change among users belonging to the most generic household tariff G11 with a single electricity rate per KWh (Kilowatt hour) regardless time of use. The article analyzes the electricity purchase and supply costs of the largest households group belonging to G11 tariff and simulates the effectiveness of moving from existing tariff group to the offered competitive tariff according to electricity suppliers.

Nowadays, the data are available in a variety of formats such as relational data-base tables, xml files, rdf files or simply text files. Database systems have their own query languages and tools for the manipulation of data. On the other hand, most of todays applications are created in languages based on the object-oriented paradigm. From the level of the programming language it is important to use different sources of data in a uniform manner. The paper discusses the elements of the various query languages such as SQL XQuery or SPARQL. And then shows the capabilities of LINQ and its role in the creation of abstract data access layer. Then the possibilities of LINQ extension are discussed. As the example, design and implementation of LINQ provider for Allegro is presented.

The paper presents selected results of research on the use of artificial intelligence methods, which are inspired by quantum computing solutions for modelling of electric power exchange systems. Methods used in the modelling of quantum data acquisition, quantization and dequantization of information as well as the methods of performing quantum computations were emphasized. Furthermore, we have analysed the results obtained for the neural model and for the evolutionary algorithm inspired by the quantum computer science. Eventually, the model was verified on the example of the neural model of the Electric Power Exchange (EPE).

Processing massive data amounts and Big Data became nowadays one of the most significant problems in computer science. The difficulties with education on this field arise, the appropriate teaching methods and tools are needed. The processing of vast amounts of data arriving quickly requires the choice and arrangement of extended hardware platforms.In the paper we will show an approach for teaching students in Big Data and also the choice and arrangement of an appropriate programming platform for Big Data laboratories. Usage of an e-learning platform Moodle, a dedicated platform for teaching, could allow the teaching staff and students an improved contact with by enhancing mutually communication possibilities. We will show the preparation of Hadoop platform tools and Big Data cluster based on Cloudera and Ambari. The both solutions together could enable to cope with the problems in education of students in the field of Big Data.

Accession of Poland to the European Union meant that its eastern border became the external frontier of the Community. The next step in the European integration was joining the Schengen Zone by Poland. Polish citizens may freely travel throughout the Schengen Zone and the state was obliged to tighten its eastern border. Under these circumstances conducting research on passenger traffic has become a vital issue, with particular focus on the eastern frontier. In the article an attempt is made at examining the possibility of forecasting passenger traffic on the example of border crossing points between the Subcarpathian Province and Ukraine using the ARIMA models. Confirmation of these possibilities seems to be crucial as the number of people crossing the border is characterized by high variability and sensitivity to the political situation. The study is based on the information provided by the Polish Border Guard. The conducted time series analysis is of a multi-purpose character. It may be used to support decision making processes of investment, organizational, as well as socio-political nature.

This article presents differences between Enterprise Resource Planning Systems and Warehouse Management Systems. Management of warehouse processes and hardware requires specialized functionality, not present in ERP, functionality that only WMS can provide. Using separate systems enforces their integration. Different approaches to integration and risks connected to implementation are discussed and summarized.
