The algorithm for the detection of positive and negative text
Musil, David ; Harár, Pavol (referee) ; Povoda, Lukáš (advisor)
As information and communication technology develops swiftly, amount of information produced by various sources grows as well. Sorting and obtaining knowledge from this data requires significant effort which is not ensured easily by a human, meaning machine processing is taking place. Acquiring emotion from text data is an interesting area of research and it’s going through considerable expansion while being used widely. Purpose of this thesis is to create a system for positive and negative emotion detection from text along with evaluation of its performance. System was created with Java programming language and it allows training with use of large amount of data (known as Big Data), exploiting Spark library. Thesis describes structure and handling text from database used as source of input data. Classificator model was created with use of Support Vector Machines and optimized by the n-grams method.

Advanced analysis of spontaneous spoken dialogues
Musil, David ; Burget, Radim (referee) ; Atassi, Hicham (advisor)
First part of this thesis contains information about call centers. This chapter focuses at their origin and history and basic division of software call centers use. Second chapter contains ways of processing speech and methods for call quality evaluation. Next chapter provides a description of basic dialogue features such as reaction, hesitation and interruption. Following chapters contain desing and description of graphic environment designed in Matlab programming language for previously mentioned basic dialogue features from data provided by thesis supervisor and their use for conversation analysis. Second part of thesis describes the process of creation a call assessment. It includes gathering necessary data for this part of thesis, their subsequent modification, usage and discussion of results and foundings.

Makroekonomický vývoj a produkce osobních automobilů v České republice
Musil, David
The automotive industry is one of the most important industries in the Czech Republic. It represents a very significant part of all major macroeconomic aggregates. This work will be focused on the factors which influence the export of cars manufactured in the Czech Republic. A huge amount of Czech cars is exported to the European Union. Therefore, the influence of macroeconomic aggregates in the European Union will be examined. These macroeconomic aggregates are gross domestic product per capita, inflation, unemployment, exchange rate and interest rate of consumer loans. The work will be focused on individual carmakers and will include three models of amount of cars produced by Škoda, TPCA and Hyundai.

Algorithm for Detection of Positive and Negative Text
Musil, David
In the present, obtaining and sorting knowledge from data produced by various sources requires significant effort which is not ensured easily by a human, meaning machine processing is taking place. Purpose of this work was to create a system capable of positive and negative emotion detection from text along with evaluation of its performance. System allows training with use of large amount of data (known as Big Data), exploiting Spark library. Classificator model was created with use of Support Vector Machines. Highest achieved accuracy is 78,05% for Czech, 79,73% for German and 91,88% for English.
