Deep Neural Networks Used for Customer Support Cases Analysis
Marušic, Marek ; Ryšavý, Ondřej (referee) ; Pluskal, Jan (advisor)
Umelá inteligencia je pozoruhodne populárna v dnešnej dobe, pretože si dokáže poradiť s rôznymi veľmi komplexnými úlohami v odvetviach ako napr. spracovanie obrazu, spracovanie zvuku, spracovanie prirodzeného jazyka a podobne. Keďže Red Hat doteraz už vyriešil obrovksé množstvo zákazníckych požiadavkov počas podpory rôznych produktov. Preto bola navrhnutá myšlienka použiť umelú inteligenciu práve na tieto dáta a docieliť tak zlepšenie a zrýchlenie procesu riešenia zákaznícky požiadavkov. V tejto práci sú popísané použité techniky na spracovanie týchto dát a úlohy, ktoré je možné riešiť pomocou hlbokých neurónových sietí. Taktiež sú v tejto práci popísane rôzne modely, ktoré boli vytvorené počas riešenia tejto práce a snažia sa adresovať rôzne úlohy. Ich výkony sú porovnané na spomínaných úlohách.

Natural language communication with Robots
Pišl, Bedřich ; Mareček, David (advisor) ; Variš, Dušan (referee)
Interpreting natural language actions in a simulated world is the first step towards robots controlled by natural language commands. In this work we present several models for interpreting unrestricted natural language commands in a simple block world. We present and compare rule-based models and recurrent neural network models of various architectures. We also discuss strategies to deal with errors in natural language data and compare them. On the Language Grounding dataset, our models outperform the previous state-of-the-art results in both source and location prediction reaching source accuracy 98.8% and average distance 0.71 between the correct and predicted location.

Unsupervised and Semi-Supervised Multilingual Learning for Resource-Poor Languages
Tran, Manh-Ke ; Zeman, Daniel (advisor) ; Vidová Hladká, Barbora (referee)
This thesis focuses on unsupervised morphological seg- mentation, the fundamental task in NLP which aims to break words into morphemes. I describe and re-implement a model proposed in Lee et al. (2011) and evaluate it on 4 languages. Moreover, I present a generative model that could use word representation as extra fea- tures. The word representations are leant in unsupervised manner using neural language model. The experiment shows that using extra features improves the performance of the unsupervised model.

Multilingualism in sound film
Hamerlová, Dana ; Mareš, Petr (advisor) ; Bozděchová, Ivana (referee)
This thesis deals with issues of multilingualism, i. e. appearance of two or more different languages, in a film. The first part of the thesis provides an introduction to the theory of communication, then follows a brief look at the character of film communication, i. e. its primary and secondary stucture. The second part concerns with multilingualism on both levels of communication in film discourse. The author discusses filmmaker's intentions related to comprehension or incomprehension of a foreign-language text and establishes the functions of multilingualism. The following parts research three separate film categories whose classification is based on types of languages that appear in film. The first category embraces films in that several different real spoken languages figure, the second one includes films where real spoken language and fictional language appear, films of the third category present spoken language and means of communication used by deaf people. Keywords sound film, communication, multilingualism, natural language, sign language, fictional language

XMPP Robot with Natural Language Interface
Krygielová, Magdaléna ; Fapšo, Michal (referee) ; Schmidt, Marek (advisor)
This bachelors thesis describes an XMPP robot which communicates using natural language. It works as an interface for various services, especially for providing information about train and bus connections. This robot allows people using Jabber network to get the information about implemented services the way which is natural for them, without the need of filling forms or remembering command formats.

Encyclopedia Expert
Krč, Martin ; Schmidt, Marek (referee) ; Smrž, Pavel (advisor)
This project focuses on a system that answers questions formulated in natural language. Firstly, the report discusses problems associated with question answering systems and some commonly employed approaches. Emphasis is laid on shallow methods, which do not require many linguistic resources. The second part describes our work on a system that answers factoid questions, utilizing Czech Wikipedia as a source of information. Answer extraction is partly based on specific features of Wikipedia and partly on pre-defined patterns. Results show that for answering simple questions, the system provides significant improvements in comparison with a standard search engine.

An Automatic Configuration of Services of Operating System
Schiffer, Peter ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
This Master thesis describes the configuration of operating systems and their capabilities. It introduces differences between configuration of different operating systems according to their specialization, and it introduces advanced configuration of operating systems with third-party applications. The practical part of the thesis is a design of a new computer language aimed at describing a configuration of an operating system and its services. Such a description is used to automatically configure system services by translating it to a sequence of configuration commands. An advantage of the language is its readability by a human, but its similarity with natural languages introduces a certain level of ambiguity. The proposed method of automatic generation of commands deals with the ambiguity by searching and selecting as least as possible destructive commands.
