Két egészségügyi vonatkozású adatvédelmi peres eljárás eddigi eredményeit mutatom be írásomban. Magyarországon adatvédelemmel kapcsolatos pereket általában nehéz indítani, mert az adatkezelésekre minden esetben jogi kötelezettségként, azaz állami kényszerintézkedés alkalmazásával kerül sor. Ez a jogtechnikai megoldás eleve kizárja a lehetőségét, ho...

Az anonimizálás célja az, hogy a személyes adatokat átalakítsa olyan módon, hogy azok már nem kapcsolathatók össze természetes személyekkel. Az anonimizálás megfelelő validálás nélkül magában hordozhatja azt a kockázatot, hogy az adatokat később mégis természetes személyekhez lehessen kapcsolni. Amikor ez kiderül, rendszerint jóvátehetetlen kár köv...

Full-text available
Anonymization is viewed as an instrument by which personal data can be rendered so that it can be processed further without harming data subjects' private lives, for purposes that are beneficial to the public good. The anonymization is fair if the possibility of re-identification can be practically excluded. The data processor does all that he or s...
Conference Paper
Full-text available
The language of patent claims differs from ordinary language to a great extent, which results in the fact that tools especially adapted to patent lan-guage are needed in patent processing. In order to evaluate these tools, manually annotated patent corpora are necessary. Thus, we constructed a corpus of English language pharmaceutical patents belon...

Conference Paper
From the point of view of computational linguistics, Hungarian is a diffcult language due to its complex grammar and rich morphology. This means that even a common task such as part-of-speech tagging presents a new challenge for learning when looked at for the Hungarian language, especially given the fact that this language has fairly free word ord...
Article
In this paper a model is proposed for the parallel execution of OFL programs on MIMD architecture. OFL can be considered as a target language for object-oriented query compilers or a convenient source language for object-oriented query interpreters. The proposed OFL executor model uses the pipelined evaluation strategy to process queries.
Article
The IDT (Interactive Diagnosis and Testing) system is presented which extends Shapiro’s Interactive Diagnosis Algorithms with Category Partition Testing method. Shapiro’s original system demands a lot of user interaction during the debugging; the user has to answer a large number of queries. The results of the debugging are the buggy clause and one...
