Многоаспектная онтология электронных документов как основа функционирования информационной системы
An approach to designing and organization of information systems operation based on the processing of unstructured information presented in the electronic documents is proposed. Documents processing relies on its semantic indexing and inclusion in its additional metainformation. The paper presents a model of the document, allowing to formalize algorithms of intelligent processing documents and providing opportunities for integration document with ontological resources. Semantic indexing is based on a multidimensional ontology, which describes the structure and semantics of the document. Semantic index of document allows to apply agent-based approach for document processing, that allows to solve the problem of including business logic to documents. The system becomes more flexible, intelligent, adaptable to dynamic environments. The proposed approach allows to solve a wide range of tasks associated with the use of electronic documents in the information system at all stages of their life cycle. That makes possible to use term suggesting that the “document-oriented paradigm” to support the whole life cycle of information system.
In this paper authors wish to present an approach to information modeling and software design suitable for developing evolvable semantic applications in the domain of research team formation. The novel proposals include specialization of generic paradigm of ontological engineering, specific types of machine-readable RDF ontologies and application of temporal look at information relevant for team formation. In order to validate theoretical approach a software prototype of the evolvable web-based semantic platform InfoPort was developed.
It turns out, however, that in spite of one basic difference there runs between these two systems a deep and striking parallelism. This parallelism is so close indeed that it makes possible the construction of a vocabulary which would transform characteristic propositions of Wittgenstein's ontology into Aristotelian ones, and conversely. To show in some detail the workings of that transformation will be the subject of this paper.
We describe a novel method for the analysis of research activities of an organization by mapping that to a taxonomy tree of the field. The method constructs fuzzy membership profiles of the organizationmembers or teams in terms of the taxonomy’s leaves (research topics), and then it generalizes them in two steps. These steps are: (i) fuzzy clustering research topics according to their thematic similarities in the department, ignoring the topology of the taxonomy, and (ii) optimally lifting clusters mapped to the taxonomy tree to higher ranked categories by ignoring “small” discrepancies. We illustrate the method by applying it to data collected by using an in-house e-survey tool from a university department and from a university research center. The method can be considered for knowledge generalization over any taxonomy tree.

The article considers the conceptual approach of creating a set of development tools for active learning methods in a form of competency-based business-game studio. Competence-based business game is an information system, which aims to give a certain level of professional competence while implementing scenarios that are determined by business-process models of the domain. The structure of the gaming studio, suggests a set-theoretic representation of business-game design process. Business game can be represented as a cybernetic system with feedback, which contains both the object of management and the management system. The game is implemented as control and operating machines accordingly. For the construction of the operational machine it is proposed to use a knowledge model in the form of ontology. To represent the automate model it is proposed to use a model of managing business processes of an enterprise. A block diagram of the business-game design process is provided.
In the paper integrated information systems for corporate planning and budgeting are considered. Four groups of practical tasks exceeding the bounds of typical functionality of special-purpose planning and budgeting information systems are allocated. Several classes of information systems (simulation, statistical analysis, financial analysis and modeling, group decision making, business intelligence), which may provide the completeness of corporate planning and budgeting are denoted as solutions complementary to special-purpose planning and budgeting systems.
In this work the problem of learning and development of creativity with a view to the position of reflexive psychology, akmeology and pedagogics in the context of the human capital analysis in the conditions of modern society globalization is raised. The theme is urgent from the practical point of view in demand of a creative personality under conditions of the economic crisis and at the same time it is actual, because it interprets creativity in a new way according to interdisciplinary approach. The author emphasizes that a reflexively-creative potential is considered to be the backbone factor of professional and innovative activity in modern social space. On basis of philosophical foundations' analysis of psychology of creativity we theoretically build the conceptual model of reflexive creativity and we also examine the precedents of its psychology-pedagogical development in the secondary and high education (in case of reflexive-psycological support).
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
