Hálek, Ondřej ; Šebesta, Michal (advisor) ; Vojíř, Stanislav (referee)
The thesis is focused on creation of B2B market place design to support small and medium size enterprises. It is based on research of issues of small and medium size enterprises and system complexity. Study of logistics, logistic distribution and contemporary supply chains in the Czech Republic from the point of view of small and medium size enterprises is another part of the thesis. The design is based on research of semantic web and is created according to MMSP methodology. The design is created to eliminate pressure points of studied areas such as small ability of semantic web to become a communication system used in exchange of enterprises' offers and demands, limited cooperation of small and medium enterprises, prices which do not depend on logistics costs and door to door deliveries which supports the prominent position of large retail companies.

Music scores notation support system
Rejthar, Edvard ; Vojíř, Stanislav (advisor) ; Smutný, Zdeněk (referee)
Musicians need to notate their melody into music scores. If they use paper (which is highly comfortable), they lose the digitalizing advantages -- easy sharing and computer playback. On the other side, computer user interface has not been adjusted for music notation and the control of music editors is not trivial. So musicians tend to notate the music in plain text. The innumerable count of internet songbook can serve us as an example where the music is in a minimalistic way indicated by chord marks, positioned above the lyrics. Nevertheless, this plain text can not by easily played. Our work concerns program Mordent that tends to serve as a connecting link between plain text and music score. It is an application for musicians; it is written in object-oriented PHP and uses typesetting processor Lilypond to create PDF, PNG, and MIDI files from user input. First version of the application was limited and not much user-friendly. The user testing brought some new improving suggestions. This work documents the course of the testing and significant changes that extended the application: new editor behaviour, mobile-devices compatible redesign, and eventually the set of games, suitable for practising of musical hearing ability and music theory.

Knowledge management system in the form of knowledge network
Vojíř, Stanislav ; Chocholatý, Drahomír (advisor) ; Chlapek, Dušan (referee)
Knowledge is one of the most important values of companies, work-teams and other organizations. It is one of competitive advantages and so it is important to share the knowledge among individuals in the organization. The discipline of knowledge management deals with the issue of systematic work with knowledge and sharing for several decades. The sharing and finding of knowledge should be supported via suitable software tools, currently using the Internet network. This work deals with problematic of knowledge management from the viewpoint of different methods of software support. The text approaches the problem of sharing of knowledge in a hypertext form. The problem is solved not only on theoretical base, but also from the viewpoint of system design and implementation. The knowledge is saved in the form of "knowledge network" based on text contents, authors and keywords. The data are saved in the form of RDF graph using PHP and ARC2 Framework. The developed system will be used not only for support of dealing with knowledge in the courses of project management at University of Economics in Prague.

Mapping of PMML and BKEF documents using PHP in the SEWEBAR CMS
Vojíř, Stanislav ; Kliegr, Tomáš (advisor) ; Zamazal, Ondřej (referee)
In the data mining process, it is necessary to prepare the source dataset - for example, to select the cutting or grouping of continuous data attributes etc. and use the knowledge from the problem area. Such a preparation process can be guided by background (domain) knowledge obtained from experts. In the SEWEBAR project, we collect the knowledge from experts in a rich XML-based representation language, called BKEF, using a dedicated editor, and save into the database of our custom-tailored (Joomla!-based) CMS system. Data mining tools are then able to generate, from this dataset, mining models represented in the standardized PMML format. It is then necessary to map a particular column (attribute) from the dataset (in PMML) to a relevant 'metaattribute' of the BKEF representation. This specific type of schema mapping problem is addressed in my thesis in terms of algorithms for automatic suggestion of mapping of columns to metaattributes and from values of these columns to BKEF 'metafields'. Manual corrections of this mapping by the user are also supported. The implementation is based on the PHP language and then it was tested on datasets with information about courses taught in 5 universities in the U.S.A. from Illinois Semantic Integration Archive. On this datasets, the auto-mapping suggestion process archieved the precision about 70% and recall about 77% on unknown columns, but when mapping the previously user-mapped data (using implemented learning module), the recall is between 90% and 100%.

Extension development for CMS Joomla!
Vojíř, Stanislav ; Nemrava, Jan (advisor) ; Kliegr, Tomáš (referee)
Writing of analytical reports in natural language is important, but not very simple. At this time, most of analytical reports are written in Microsoft Word and saved as classical files. The object of this bachelor thesis is the change to simpler writing of analytical reports in online application CMS Joomla!. To this functionality, we use some extensions of CMS Joomla!. After demands definition, we use an exitor-xtd plug-in and a component for CMS Joomla! 1.5. Using extensions, which were written in this thesis, authors of analytical reports are able to select part of dates from data mining application and insert this part to edited analytical report. The data source for including is xHTML presentation of data from data mining application. In this bachelor thesis, there are described information about dividing of xHTML document, part selection and including to the edited text. The secondary functionality of build extensions is updating of included blocks in selected analytical report. Users can select finished analytical report and update the included blocks with newer data. At the University of Economics, Prague, all students of informatics learn about fundamental data mining in the subject 4iz210 - Information and Knowledge Processing. In this subject, the students will use CMS Joomla! with extensions from this bachelor thesis. The start-up mounting will be at the end of summer semester in academically year 2008-2009. This bachelor thesis could be used as inspiration for extension development for CMS Joomla!, too.
