Классификация и каталогизация информационных ресурсов сферы образования
For management of information resources (IR) the Russian educational system the uniform specification of metadata used for the description and classification of the information - and in educational portals, and in registration system, and in storehouses of data should be developed and accepted. In the present work specified concept of IR as object of cataloguing is given, requirements to the metadata describing educational IR are considered, qualifiers for use in metadata and at last are listed, conclusions are drawn on an accepted way of system engineering of the metadata allowing uniformly to describe and classify IR of education under their maintenance and the user characteristics.
The complex approach to the decision of a problem of systematization of information resources for education sphere is offered. The approach assumes creation of the multilevel national network infrastructure forming space for interaction of all participants of processes for creation, distribution and application of information resources. The generalized scheme of such infrastructure is developed, its structure and construction principles are defined. Models of the metadates information resources for an education sphere of Russia and open freely extended tool means supporting them are described.
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
