We present the user-centered, iterative design of Mobile Facets, a mo-bile application for the faceted search and exploration of a large, multi-dimensional data set of social media on a touchscreen mobile phone. Mo-bile Facets provides retrieval of resources such as places, persons,...

The paper is devoted to solving the problem of assessing the quality of the medicalelectronic service. A variety of dimensions and factors of quality, methods and models applied indifferent scopes of activity for assessing quality of service is researched. The basic aspects,requirements and...

One of the key factors that hinders integration of distributed, heterogeneousinformation systems is the lack of a formal basis for modeling the complex, structuredknowledge that is to be exchanged. To alleviate this situation, we present anapproach based on core ontologies. Core ontologies are...

This paper describes the analysis of a neural network used to predict currencyexchange rates in comparison to technical analysis. The neural network structuresused are a multilayer perceptron and a Volterra network.[...]

The paper is devoted to solving a problem of the development of the website of Russianmunicipal policlinics and provides a selection of a set of elements which should be posted on awebsite. Such elements are necessary to provide citizens with correct and ergonomic e-services.The insufficient...

This paper describes parallel algorithms for training articial neural networks.Possible levels of parallelity are presented. Experiments for checking the efficiencyof algorithms are discussed.[...]

The estimation of various social objects is necessary in different fields of social life, science,education, etc. This estimation is usually used for forecasting, for evaluating of different propertiesand for other goals in complex man-machine systems.[...]

This paper has a twofold concern. First, to show that probabilitypropagation nets (PPNs) can be derived from formulae for conditionalprobabilities. Second, to show that PPNs are usable for (local)propagations of mass distributions, too, if the inscriptions are suitablyadapted.[...]

Knowledge compilation is a common technique for propositionallogic knowledge bases. A given knowledge base is transformedinto a normal form, for which queries can be answered efficiently. Thisprecompilation step is expensive, but it only has to be performed once.We apply this technique to...

In vielen Köpfen – sowohl bei Erwachsenen wie auch bei Schülern – geistert der Glaube, dassInformatik die Wissenschaft der „Computerlehre“ ist. Schon der berühmte Satz „In derInformatik geht es genauso wenig um Computer wie in der Astronomie um Teleskope“, derdem Informatiker...
