Vocabulary used by the doctors to describe the results of medical procedures changes alongside with the new standards. Text data, which is immediately understandable by the medical professional, is difficult to use in mass scale analysis. Extraction of data relevant to the given case, e.g. Bethesda class, means taking on the challenge of normalizing the freeform text and all the grammatical forms associated with it. This is particularly difficult in the Polish language where words change their form significantly according to their function in the sentence. We found common black-box methods for text mining inaccurate for this purpose. Here we described a word-frequency-based method for annotation of text data for Bethesda class extraction. We compared them with an algorithm based on a decision tree C4.5. We showed how important is the choice of the method and range of features to avoid conflicting classification. Proposed algorithms allowed to avoid the rule-base limitations.

This paper introduces the application possibilities of long-period waveguide gratings produced in gradient structures of planar waveguides and their possible usage as the detectors of changes in the refractive index.The inuence of technological processes and corrugation's parameters on the resonant characteristics and transmission spectrum (obtained by the numerical simulations) of such structures was presented.The inuence of changes in the refractive index of the environment on the transmission spectral characteristics was shown.The possibilities of sensor applications of such structures was presented as well.The calculations were performed for two types of gradient waveguides' structures: produced in BK7 glass with the use of K + ↔ Na + ion exchange and produced in soda-lime glass with the use of Ag + ↔ Na + ion exchange.

The paper presents an approach to designing complex IT systems based on the EAI architecture. Enterprise Application Integration (EAI) is an integration framework composed of a collection of technologies, methods, and tools aimed at modernizing, consolidating, and coordinating IT systems. The work also gives a description of the possibility of using Biztalk Server as the software platform to implement systems integration infrastructure. An example of a system that can provide an important part of complex integrated system is the GRANICE system. Although the GRANICE system is fully functional environment, using the integration platform which is an intermediary in the communication with other systems,we can significantly extend its functionality.Keywordsintegration of IT systemsservice-oriented architectureenterprise application integrationBiztalk servermessagepipelineorchestrationsystem GRANICE

Determining the current position of the flying platform is one of the key elements of the IT system developed for the project GRANICE (BORDERS). Enabling the operator to trace the flight route and current position allows to send a patrol to a precisely defined place and support its operation from the air. The developed system will be equipped with a WWW application for tracing the vehicle position, creating missions by defining checkpoints and specifying tasks for them. The application will support layers and will enable defining alarms and warnings associated with the layers. The layer management module will give the user full control over adding, editing, deleting and displaying layers. The operator controlling the unmanned flying platform should also be able to read basic parameters of the platform’s flight. A characteristic feature of the map application is a necessity for working with actual data received from the communication module and historical data stored in a central database. During daily operation the system will display data received directly from the flying platform, whereas data store in the central database will be used to create reports, summaries and restoring historical routes.
