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.

Automatic Evaluation of e-Learning Tests
Hort, Jan ; Fapšo, Michal (referee) ; Smrž, Pavel (advisor)
The thesis is dealing with research of automatic evaluation of e-learning tests. That technology is useful for domain of computer aided learning and e-learning and intelligent tutoring systems. This is extending possibility of online testing the student's knowledge. This thesis is also dealing with norms for learning and intelligent tutoring systems. Briefly introduce some project of domain of intelligent tutoring systems.

Mobile personal assistants
Techl, Jan ; Sigmund, Tomáš (advisor) ; Labský, Martin (referee)
This thesis focuses on analysis, definition and description of mobile personal assistants as a phenomenon emerging in past few years. Mobile personal assistants are first mentioned in the context of computational linguistics and information needs, which is one of the motivations to use them. Main interest of this thesis is an introduction of the core technologies for the natural language communication between the assistant and its user, followed by an introduction of host environments and possible usage. The thesis also presents the limitations and risks resulting from using them, which are in some ways affecting their usability. Beside the analysis the main focus is on the design and implementation of the natural language understanding (NLU) system, which can be used in particular personal assistant application. This system is implemented as a web service and consists of an annotation scheme with a set of components. The results show that the system architecture and tools used are suitable solution for the construction of a basic NLU system, which has been created and which is in the compliance with the requested parameters. It is still difficult task to achieve high precision, which depends on many factors including the amount of training data, which was very small in this case. However, the resulting application is a solid starting point for its further development and extensions.
