In the paper the method of collecting, processing and sharing information along food chain is presented. Innovative features of that method result from advantages of data engineering based on semantic technologies. The source to build ontology are standards and regulations related to food production, and data collected in databases owned by food chain participants. It allows food chain information resources can be represented in semantic languages RDF/RDFS/OWL and form semantic database where data are easily integrated according to various criteria using automatic inference algorithms. Feasibility of proposed method is achievable with Ontorion Knowledge Framework.

Evidence-based medicine can be effective only if constantly tested against errors in medical practice. Clinical record database summarization supported by a machine allows allow to detect anomalies and therefore help detect the errors in early phases of care. Summarization system is a part of Clinical Decision Support Systems however it cannot be used directly by the stakeholder as long as s/he is not able to query the clinical record database. Natural Query Languages allow opening access to data for clinical practitioners, that usually do not have knowledge about articial query languages. Results: We have developed general purpose reporting system called Ask Data Anything (ADA) that we applied to a particular CDSS implementation. As a result, we obtained summarization system that opens the access for these of clinical researchers that were excluded from the meaningful summary of clinical records stored in a given clinical database. The most significant part of the component - NQL parser - is a hybrid of Controlled Natural Language (CNL) and pattern matching with a prior error repair phase. Equipped with reasoning capabilities due to the intensive use of semantic technologies, our hybrid approach allows one to use very simple, keyword-based (even erroneous) queries as well as complex CNL ones with the support of a predictive editor. By using ADA sophisticated summarizations of clinical data are produced as a result of NQL query execution. In this paper, we will present the main ideas underlying ADA component in the context of CDSS.

This paper describes the approach to interface for OWL Knowledge Bases based on Controlled English that is transformed directly to OWL 2 expressions and back. Two possible modes enable usage of the interface to specify Terminology, World Description as well as Integrity Constrains. Knowledge Base then can be validated against the Integrity Constrains to enable its continuous validation.

W artykule przedstawiono interfejs dla baz wiedzy, stworzony na podstawie kontrolowanego języka angielskiego, który to jest przekształcany bezpośrednio do wyrażeń OWL 2 i z powrotem. Wskazano dwa tryby pracy, opierające się na tym interfejsie, umożliwiające zapisywanie terminologii bazy wiedzy oraz opisu świata, jak również na zapisie ograniczeń wewnętrznych bazy wiedzy. Taka baza wiedzy może być następnie automatycznie kontrolowana pod kątem ww. ograniczeń.

The knowledge stored in Ontology Management Systems (OMS) that originally has the form of expressions, can be seen as a user application specification or as knowledge provided by an expert. The generator of applications discussed in this paper is defined as a program that automatically generates an application that meets a certain specification stored in OMS. It is shown that it is possible to build a user interface for data management with an algorithm that crawls over taxonomy inferred by the description logic reasoner. Finally, an example prototype of a medical application will be discussed to prove the feasibility of the proposed approach.

Annual Hawaii International Conference on System Sciences (HICSS'04). W artykule przedstawiono generator aplikacji zbudowanych na bazie Systemu Zarządzania Ontologiami (ang. Ontology Management System - OMS). Jako że logika opisowa może służyć do zapisu schematu bazy danych, zawartości bazy danych, jak również ograniczeń w jednolity sposób, omawiany tu generator jest programem, który może automatycznie tworzyć aplikacje spełniające dane specyfikacje. Przedstawiono również algorytm, który tworzy interfejs użytkownika, używając architektury MVC (Model/Widok/Kontroler). W końcowej części omówiono przykład prototypu systemu medycznego wykorzystującego opisane tutaj podejście.
