Integration of medical information systems
Kusák, David ; Nečaský, Martin (advisor) ; Dvořáková, Jana (referee)
This Bachelor thesis examines ways of integration of various Hospital Information Systems (HIS) in frame of heterogenous interoperable platform. Thanks to that, exchange of information from Electronic Health Record (EHR) between HISes is enabled. A Modern approach to integration of systems should put emphasis on standardization of communication. The solution of communication described in this thesis is based on HL7 standard, which is one of the most perspective standard for transfer medical informations. The bachelor thesis contains a part of integration of cardiological information system AdamekJ into the network of another HISes. Integration of these systems is based on HL7 standard and is being solved in frame of the project 1ET200300413AVR on Department of Medical informatics ICS ASCR.

Exploitation of Linked Data for sharing public agreements data
Hryzlík, Pavel ; Nečaský, Martin (advisor) ; Škoda, Petr (referee)
Title: Exploitation of Linked Data for sharing public agreements data Author: Bc. Pavel Hryzlík Department: Department of Software Engineering Supervisor: Doc. Mgr. Martin Nečaský, Ph.D., Department of Software Engineering Abstract: The objective of the thesis is to explore the possibilities of using Linked Data principles for publishing and sharing data on contracts of public institutions and their connections to related data in the public domain (eg. Business and trade register, register of contracts, etc.). Thesis presents the entire process of opening up contracts. Defines a data standard for open contracts and proposes an ontology for the publication of data on contracts and their interconnections. Furthermore, it designs and implements a platform for publishing contracts. The first part of the platform is a conversion module enabling the conversion of contracts stored in relational databases into RDF form. Employed are R2RML mapping techniques. The second part is a uniform repository that downloads data on contracts in Linked Data format. The third part is a web application that will make the data on contracts available to end users. Keywords: Contract, Open Data, Linked Data, RDF, JSON-LD, R2RML, SPARQL Powered by TCPDF (www.tcpdf.org)

Querying RDF graphs stored in a relational database using SPARQL and R2RML
Chaloupka, Miloš ; Nečaský, Martin (advisor) ; Kopecký, Michal (referee)
The RDF framework is becoming a popular framework for presenting data. It makes the data easily accessible and queryable. But the most common way how to store structured data is to use a relational database systems. The relational databases benefit from their long theoretical and practical history, however the relational database does not offer any convenient way how to publish the data. It is essential to create a mapping between these two worlds, to publish the data stored in a relational database in the RDF format. In the presented work we study the SPARQL algebra and create a transformation algorithm that enable us to create a virtual SPARQL endpoint over the relational data. We apply the acquired knowledge in implementation of a tool which uses the algorithm to proof the concept. Powered by TCPDF (www.tcpdf.org)

Správa knihovny
Marchenko, Maryna ; Nečaský, Martin (advisor) ; Klímek, Jakub (referee)
In the given thesis all the steps of studying and writing a program for the management of a library are worked out. In the rst chapter the requirements of the client ordering this software are analyzed. The possible solutions are o ered. In the next part a study about barcodes and barcode readers is given, as the books and users of the library will be given barcodes. The third chapter includes a precise user documentation, explaining how to use the program. Next there is a programmer documentation explaining some interesting parts of the code and introducing the programming language that was chosen. It is then that a conclusion is made and possible future improvements are proposed.

Products Catalogue Configuration Framework
Dzurenko, Miroslav ; Nečaský, Martin (advisor) ; Kopecký, Michal (referee)
Market segmentation is growing as customers become more and more demanding for individual products and exclusive services. Companies are introducing new applications and products across many industries , that can be tailored easily to specific customers and markets. To be successful, the organisations have to offer a high level of customisation and customer-centric processes. However, traditional companies in financial, telecommunication and insurance industry struggle with the technological challenges associated with becoming customer focused enterprises. The aim of this thesis is to define the products catalogue framework, that will provide products bundling and customisation capabilities with user-friendly GUI. Therefore, the most of the work can be designed by business users without additional intensive development efforts. Moreover, the viability of the framework was evaluated on the solution based on IBM technologies. Powered by TCPDF (www.tcpdf.org)

Structured Data Extraction from Unstructured Text
Kóša, Peter ; Nečaský, Martin (advisor) ; Kopecký, Michal (referee)
Title: Structured Data Extraction from Unstructured Text Author: Bc. Peter Kóša Department: Department of Software Engineering Supervisor: Mgr. Martin Nečaský, Ph.D., Department of Software Engineering Abstract: In the last 20 years, there has been an ever-growing amount of information present on the Internet and in published texts. However, this information is often in a non-structured format and this causes various problems such as the inability to efficiently search in diverse collections of texts (medical reports, ads, etc.). To overcome these problems, we need efficient tools capable of automatic processing, extracting the important information and storing of these results in some form for later reuse. The purpose of this thesis is to compare existing solutions as well as to compare them with our solution, which was created in the scope of software project SemJob. The SemJob project is introduced and the reader can therefore obtain knowledge about its inner structure and workings. Keywords: structured data extraction, extraction rules, ontologies, (semi)automatic wrapper induction

Comparison of commonly used SQL and NoSQL data storages
Čečil, Petr ; Nečaský, Martin (advisor) ; Holubová, Irena (referee)
Data storing is today very important topic. Because of Web 2.0 and software-as-a-service applications there is growing need for scalability and new types of data stores. The aim of this thesis is to help understand competing SQL and NoSQL data stores and their target use cases. Author mapped last trends in data storing and application architecture and tried to find how concrete data stores address them. There is also experimental part with benchmark and simple application that demonstrate data store's connectors and their speed.

Mapping of relational schema onto existing ontologies
Marko, Peter ; Tykal, Jaroslav (advisor) ; Nečaský, Martin (referee)
This master thesis concerns the problematics of mapping of relational schemas to existing ontologies, primarily written in RDFS. Its first part gives a view at already existing solutions and their principles. The solutions are divided into the manual and semiautomatic groups according to the level of a help given to users when mapping. Secondly the thesis presents an own solution - mDR. In its basics it does use ideas of the existing FDR2 system, however it generalises them. The mapping is done in three steps: creation of helping information about a database, mapping and instances transfer. The last third of the work involves JmDR, a (in JAVA) developed tool completely implementing the first two phases.

Špaňo, Martin ; Nečaský, Martin (advisor) ; Hoksza, David (referee)
Web application frameworks accelerate the development of web information systems. There are many frameworks available to developers these days. This work tries to find suitable criteria for their comparison. Three popular web frameworks based on Java programming language - Spring, Seam and Struts 2 were compared according to these criteria. The comparison includes the implementation of small information system in all three frameworks and performing measurements on these implementations. The results of comparisons and measurements were analyzed and recommendation for the deployments of compared frameworks in different conditions were given based on these results.
