Data Acquisition from HTML Sites
Komenda, Tomáš ; Šimek, Václav (referee) ; Straka, Martin (advisor)
This work describes scope of creating application for extraction and following data from HTML sites. This work engages in lexical analyze and parsing HTML. This work describes filtration of data from HTML sites. This work describes saving of data in database and XML documents, creating of dynamic HTMP pages, timer cron, GNU utility wget, sending of SMS, sending email and extraction of date from internet. Final chapters describe two web applications. These applications follow data from HTML sites and inform users about changes.

Compiler of State Diagram Language to CHILL Language
Goldmannová, Zuzana ; Matoušek, Petr (referee) ; Ryšavý, Ondřej (advisor)
This thesis deals with the grammar of an existing proprietary state diagram language, which is used to simulate state diagrams employed in telephone exchanges. The goal of this work is to analyze the grammar and existing compiler of this language to CHILL language and also to design and implement a new compiler. This new compiler will be easier to manage and will eliminate errors and imperfections of the current arrangement. Finally this compiler is tested using existing files, that were formerly created for the current compiler, and also using files I created for testing purposes.

Context-Dependent Scanner
Hatina, Peter ; Koutný, Jiří (referee) ; Čermák, Martin (advisor)
This paper is devoted to principles of a lexical analysis and to a means of context resolution of a lexeme type, depending on its source code position. The lexical analysis, process of a lexical analyzer creation and possible solution for context lexeme recognition, based on a multiple automata system, is described. Lexical analyzer functionality is extended to accept tokens in other languages code blocks.

Script Language for Image Processing
Crlík, Radek ; Španěl, Michal (referee) ; Zemčík, Pavel (advisor)
This bachelor thesis deals with capabilities of scripting languages and their types. Specifically with design of one such language suitable for image processing. The goal was to create a language small enough, but easy to use. One of the requirement was to utilize OpenCV library, for which the resulting code would be as short as possible. First part deals with descriptions of scripting languages, their main philosophy and options of language processing by the computer. Second part contains description of the designed language. Last part documents achieved goals and possible ways how to extend the language even further.

Parsing Based on Multigeneration
Kyjovská, Linda ; Přikryl, Zdeněk (referee) ; Lukáš, Roman (advisor)
This work deals with syntax analysis problems based on multi-generation. The basic idea is to create computer program, which transforms one input string to n -1 output strings. An Input of this program is some plain text file created by user, which contains n grammar rules. Just one grammar from the input file is marked as an input grammar and others n -1 grammars are output grammars. This program creates list of used input grammar rules for an input string and uses corresponding output grammar rules for the creation of n -1 output strings. The program is written in C++ and Bison

Multiple Document Type Diff
Zemko, Michal ; Mlích, Jozef (referee) ; Chmelař, Petr (advisor)
This thesis deals with comparing different types of files, especially source codes. It describes the problem of comparing source code and different ways of solving this problem, from simple line comparison, to AST comparison. Chosen method was comparison based on lexical analysis. This is also described in the work with instruments of its automation. The goal of this thesis is to design and implement modular application, which compares different types of files. The implemented module compares source code in programming languages C/C++, Java a Python. This module is easily extendable for comparisons with other languages.

Translation of ASP into ASP.NET
Vilímek, Jan ; Ryšavý, Ondřej (referee) ; Kašpárek, Tomáš (advisor)
The goal of this dissertation is to implement an application for ASP to ASPX conversion. The ASP pages should be written in the VBScript language, the target language for ASPX will be C#. The application is developed on the .NET platform. The conversion process should be automatic. There should be no need to alter the converted files by a programmer. The first part of this dissertation introduces the whole problematic. It shows also current solutions. The next part is the analysis and the design of the application itself. The main part of this dissertation is the VBScript grammar conversion, problems while conversion and its solving.

Resolution Method Visualisation
Smetka, Tomáš ; Orság, Filip (referee) ; Rozman, Jaroslav (advisor)
This bachelor’s thesis deals with problems in the area of automated reasoning in propositional and predicate logic. In the theoretical part the propositional and predicate logic is described in connection with the system of its automatic proving with help of resolution method. Further there is described draft and implementation of a program which consists of a terminal and server part. The program looks for a proof if the given formula is impossible to be solved and visualizes every single step which leads to finding of the solution. In conclusion the implementation of solution and the thesis as a whole is evaluated and there are also described additional possibilities of extension.

General System for Testing of Interprets
Drahošová, Michaela ; Koutný, Jiří (referee) ; Lukáš, Roman (advisor)
This work deals with concept and implementation of General system for testing of interprets. Testing of interprets is based on the principle of comparation of results of the interpretation carried out by the testing with reference results. The set of testing programmes is acquired by translating testing programmes, in the reference language to programmes in the language of tested interpret. The testing system enables generation of a testing set of programmes for an interpret according input and reference result after a preceding analysis of a file consisting of description of the syntax and semantics of the interpret's language. These actions result is translation of a more complex programming language to another.

Parsing Based on Several Methods
Dolíhal, Luděk ; Goldefus, Filip (referee) ; Meduna, Alexandr (advisor)
p, li { white-space: pre-wrap; } The main goal of this work is to analyze the creation of the composite compiler. Composite compiler is in this case a szstem, which consists of more cooperating parts. My compiler is special, because its syntactic analyser consists of two parts. The work is focused on the construction of the parsers parts, on its cooperation and comunication. I will trys to scatch the teoretical backgroun of this solution. This is to be done by gramatical systems. Then I~will try to justify whether or not it is neccesary and suitable to create such a kind of parser. Last but not least I~will analyse the language, whose syntactic analyser is to be implemented by the chosen method.
