Data extraction from document scans
Macháč, Bohuslav ; Kolomazník, Jan (advisor) ; Krajíček, Václav (referee)
In this work I developed an application capable of extracting data from scanned documents. For optical character recognition, I used external OCR engine Tesseract, but it can be easily changed. I use document templates, which have informations about data areas and its data types. I tried to automatize most of the steps which are required to extract data or create new data template. User can improve or change results of these steps. For export from application I implemented components, which export data to XML, HTML or plain text. Another components can be easily added, to adapt application for various uses.

Alternative Plant Utilization for Obtaining of Significant Nature Substances: Can Weed Find a Utilization?
Wimmer, Zdeněk ; Sajfrtová, Marie ; Sovová, Helena ; Pavlík, Milan ; Svobodová, Hana ; Jurček, Ondřej ; Wimmerová, Martina
Numbers of compounds and their mixtures, which are produced by plants, can be obtained by extracting plant materials by supercritical fluids. Phytosterols and phytoecdysterotds represent an important family of these plant products. They can be used in a synthesis of supramolecular structures with possible importance for targeted effect of drugs or other biological(y active compounds. Target organisms for the compounds investigated are: (a) insects - pests and human food competitors, also important as model system in investigation of convenient application forms of biologically active compounds; (b) cell cultures used during basic pharmacological research. Supramolecular structures may form convenient matrices for practical application of the biologically active compounds. It has already been proved that numbers of medicinal or cultural plants produce important natural compounds. The present question has appeared to be answered, if so far inutile weeds may be turned into important sources of pro-drugs for disease treatments.

Stanovení vzorců selektivního chování rybářů ve statistikách českého rekreačního rybolovu
Jankovský, Martin ; Pivnička, Karel (advisor) ; Slavík, Ondřej (referee) ; Adámek, Martin (referee)
Methods for detecting patterns of angler selective fishing behaviour in the long term recreational fishery statistics are presented in this Ph.D. Thesis. The motivating idea is that mainly different anglers' fishing preferences or attitudes towards particular fish species obstruct applying anglers' catches data for ongoing use in ichthyology research. Better recognising angler selectivity is therefore judged to be the key point from the viewpoint of fish and fishery sciences. Methods affecting angler behaviour can be directly applied by other specialists, e.g. social scientists. The thesis consists of five papers two of which are published (paper 1, 2), other two of which are accepted for publishing (paper 3, 4) and the last of which (paper 5) is in the status of manuscript before submitting. In the first two papers the role of common carp catches is focused. By using multivariate techniques it is studied if the increased exploitation of carp increases also the exploitation of other fish species. Time series of carp catches serve as an explanatory variable, other species catches through the same time are processed as independent variables. According to expectations the positive effect of carp catches on those of the other species was approved at the river section with the highest expected density...

Revitalisating the city - interaction of the municipality and the citizens
Czastka, Sven ; Uherek, Zdeněk (advisor) ; Pargač, Jan (referee)
Current development in those European cities affected by its post-industrial history is designated as revitalisation. However, since many years this process has taken place in Western Europe and in the United States of America, in Czech towns has been this phenomenon quite new. Revitalisation or city revival is a complicated action encompassing different stakeholders, oscillating consecutively between construction of buildings and regeneration of citizens and their local identification. In this diploma thesis I focused on an interaction between main participants in the capital city o Usti Region - the City of Ústí nad Labem. I have identified the city administration, the city council and the civic associations and clubs as main city players. The aim of this diploma thesis was to determine the notion of revitalization and possible connotations of its usage related to cities and a concrete application in Ústí nad Labem. Furthermore to describe relations and acting of the city administration, the city council and the associations and clubs as stakeholders in the process of revitalisation. In the conclusion of this thesis I offered a few suggestions for possible more beneficent cooperation of both sides. In the course of participated observation and from the results of the inquiry has come out, that in Ústí nad...

Automated methods of textual content analysis and description of text structures
Chýla, Roman ; Smetáček, Vladimír (advisor) ; Rauch, Jan (referee) ; Uličný, Oldřich (referee)
Universal Semantic Language (USL) is a semi-formalized approach for the description of knowledge (a knowledge representation tool). The idea of USL was introduced by Vladimir Smetacek in the system called SEMAN which was used for keyword extraction tasks in the former Information centre of the Czechoslovak Republic. However due to the dissolution of the centre in early 90's, the system has been lost. This thesis reintroduces the idea of USL in a new context of quantitative content analysis. First we introduce the historical background and the problems of semantics and knowledge representation, semes, semantic fields, semantic primes and universals. The basic methodology of content analysis studies is illustrated on the example of three content analysis tools and we describe the architecture of a new system. The application was built specifically for USL discovery but it can work also in the context of classical content analysis. It contains Natural Language Processing (NLP) components and employs the algorithm for collocation discovery adapted for the case of cooccurences search between semantic annotations. The software is evaluated by comparing its pattern matching mechanism against another existing and established extractor. The semantic translation mechanism is evaluated in the task of...

Semantic Data Extractor
Beňo, Miloslav ; Eckhardt, Alan (referee) ; Zavoral, Filip (advisor)
The aim of this work is to implement a system designed to effectively extract big amounts of data from web pages. The system is able to extract data both from simple static pages as well as complicated web applications. Data extracted from the web can have all sorts of types and can be interconnected by relations having various cardinalities. Working with system is based on XML documents, into which the given task is described in a declarative way. The description of a task is based on using system components, which connected together are able to do desired functionality on general web page.

Compiling Planning Problems
Toropila, Daniel ; Chrpa, Lukáš (referee) ; Barták, Roman (advisor)
Constraint satisfaction techniques are used frequently for solving scheduling problems, but they are still seldom in AI planning. There exist several attempts to apply constraint satisfaction for solving AI planning problems, however, these techniques never became prevailing in planning and did not reach the success of, for example, SATbased planners. In this work we argue that the existing constraint models for classical AI planning are indeed not exploiting fully the power of constraint satisfaction and we propose their reformulation which significantly improves efficiency.

Web Analytics: Identification of new trends
Slavík, Michal ; Kliegr, Tomáš (advisor) ; Nekvasil, Marek (referee)
The goal of this thesis is to identify the main trends in the field of tools used to analyse web traffic. The necessary theoretical background is extracted from relevant literature and field research is chosen to gain knowledge of practitioners. Following trends have been identified: a growth in demand for Web Analytics software, an increasing interest in Web Analytics courses, an enlargment of measuring Web 2.0 and social networks, use of semantic information as the most fruitful section of academic research. The thesis also presents the main techniques of Web Usage Mining: association rules, sequential patterns, and clustering. A section about query categorization is also included. According to the field research, practitioners express most interest in clustering. The first two chapters present Web Analytics in general and introduce the main aspects of current applications. The third chapter covers theoretical research, the fifth one presents results of the field research. The fourth chapter raises the point that terminology of Web Analytics is not unified.

Set of model activities of pre-vocational rehabilitation for patients with disability
Čermáková, Michaela ; Svěcená, Kateřina (advisor) ; Rodová, Zuzana (referee)
OF THE BACHELOR THESIS Set of model activities of pre-vocational rehabilitation for patients with disability. Abstract: The thesis focuses on creating a set of model activities for patients with disability. This set was designed for practical use in the form of manual. The manual consists of seven model activities: manual work with tools, office work, activities with money, folding laundry, computer work, making a toast and washing up. I applied the set on six patients with disability and I evaluated their occupational potentional. The thesis is divided into two parts: theoretical and practical. The first part deals with the topic of the disabled, what occupation means to a person with disability and it probes into a problem with employment of the patients with disability. In the second part, I present the methodology and procedure I used in the set application on a sample of healthy population and on patients with disability. I state my observations and experience I have gained from the application of the set. It is followed by the discussion of achieved results. The final part of the thesis offers an answer to a question if it is possible to apply the set of model activities on patients with disability in order to help them find an appropriate job. Key words: disability occupational therapist...

The implementation process of operative procedures in NGO
Coufalová, Margita ; Vrzáček, Petr (advisor) ; Janouškovec, Pavel (referee)
The period we live in, is characterised by many changes - changes of economical, political and social life. These changes involve all the subjects of the national economy, including the non - governmental organisations. If these organisations want to work effectively, they have to learn, how the changes can be used for their own profit. At the same time, they have to notify own internal risk factors. There for they can learn management of changes, which has specific tools, above all the human-sources utilisation leading to the realisation of defined objectives. This thesis deals both, the theoretical issues of management of changes and its practical aspects. The practical work is based on describing the process of the formation and application new labour-procedures in NGO called Diecezni charita Plzeň. The process starts by identification of problems, determination of tools and aims. It goes on the initiation of the labor-procedures and finally concludes by the evaluation of the process.
