Corpus Processing for Foreign Language Learning
Khudiakov, Daniil ; Dytrych, Jaroslav (referee) ; Smrž, Pavel (advisor)
V Této práci se zkoumá problematika studování cizích jazyků pomocí moderních informačních technologií. Zvláštní pozornost je věnovaná především studovaní jazyků s použitím korpusu. V práci je popsán postup vývoje rozšíření pro internetový prohlížeč s účelem studování cizích jazyků. Specifikem rozšíření je možnost studenta využívat personalizované příklady použitých slov. Personalizace se opírá o slovní zásobu studenta a preferované sféře použití. Příklady použití sebraný ze zpravodajských portálů.

Implement Security Service for Preventing Internet Attacks
Fajkus, Karel ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
The main purpose of this work is to design and implement a system, that would allow to ban users based on their actions. Currently, cyber attacks have become very common, which leads to a necessity to develop great application and system protections. This project offers a solution, that could decrease a number of cyber attacks, and also prevent banning common users because of the same public IP address as attacker.

Semantic Similarity of Articles
Veselovský, Martin ; Otrusina, Lubomír (referee) ; Kouřil, Jan (advisor)
This bachelor's thesis deals with modelling of structure of semantic relationships among articles in English language. There are introduced existing methods of articles representation and computation of similarity. The base method is vector space model, which represents document as vector of words. There are given weights of importance to these words using TF-IDF method. Next, there are described advanced methods of modelling, Latent semantic analysis (LSA) and Latent Dirichlet allocation (LDA). This thesis also deals with articles, which are semantically annotated, while weights of annotation words are computed by Stochastic Gradient Descent method. Evaluation of results takes place on the prepared test corpus of documents to which there is reference similarity evaluation.

Multiword Expression Search on Android Mobile Devices
Babič, Vojtěch ; Kouřil, Jan (referee) ; Smrž, Pavel (advisor)
This thesis explores current mobile dictionary user interfaces focusing on multiword expression search support. The goal of this thesis is to design a system which can index large dictionaries and then search in them effectively. An Android application which allows user to search in multiword expressions containing inflected forms quickly was developed to demonstrate the system. A second part describes dictionary formats, their usage and features. The first dictionary format is Lexical Markup Framework, in which source dictionaries are stored and which are used to create indexed dictionaries from. Another format explained is StarDict, which was meant to be a main storage format for the implemented Android application, but an own database dictionary format supporting full-text indexes was developed instead.

Automatically Updated Bibliography
Valo, Boris ; Škoda, Petr (referee) ; Smrž, Pavel (advisor)
This paper describes the development of application for automatically updated bibliography. Nowadays, many Internet users search informations they need, this is important especially in sets of scientific publications and articles. The aim of this thesis is convenient tool for users to create their own portal. This is achieved by storing documents and their subsequent search using ElasticSearch. Retrieval is made by Boolean queries and additional search using similarity search tool MoreLikeThis. At the end of this thesis is described the way of testing and evaluation of retrieval.

Semantic Similarity of Texts
Bradáč, Václav ; Otrusina, Lubomír (referee) ; Smrž, Pavel (advisor)
This paper deals with the determination of semantic similarity texts, focusing on scalability. Part of treatment is a theoretical overview of the tools to implement the system on test data. Tested corpus contains expert articles in the English language. The aim is to analyze these articles, modified to facilitate the analysis of their semantic analogues. One of the most utilized tools is a representation of data in a vector space model.

Příprava a provedení analýzy poštovních konferencí Debianu
Buriánek, Jan ; Bruckner, Tomáš (advisor) ; Jelínek, Ivan (referee)
This bachelor thesis is devoted to techniques and technologies within area of unstructured data processing. This processing includes building an infrastructure to make it feasible and obtaining data of all Debian mailing lists contents. In order to fullfil the main goal of this thesis, there has been downloaded entire content of Debian mailing lists. Debian mailing lists are a valuable source containing information about the Debian operating system and its software components. It proves that its software components are well-made reliable open-source tools. It is expected that this source of data is able to unveil plenty of unexpected relations. Used data and technologies as the Elasticsearch search and analysis engine are excelent tools and resources to conduct research over such type of comparism of mind and computer outputs as in case of Searle's axioms from article "Is Brain's mind a computer program?". This thesis is attempting to prove that such analysis is feasible.

e-Word Of Mouth Evaluation of Czech banks on Facebook and web comments
Škola, Petr ; Novotný, Ota (advisor) ; Jelínek, Ivan (referee)
The diploma thesis analyzes internet discussions and Facebook sites that relate to banks and banking products. This analysis has been prepared for the potential value for marketing purposes, but also for other users outside the field of marketing. The main objective is to propose a regularly administered overview containing metrics and characteristics, which would provide information about the current status of the topics that were discussed at the monitored data sources. At first are described the methods of marketing research regarding to the possibility of obtaining data based from Internet discussions. Next are described the intermediate objectives. The base is description of downloading data from the mentioned sources. There have been identified two web pages and Facebook profiles of five banks, which are the data sources. Another objective is to create Java programs for downloading data and storing them in Elasticsearch. This data is enriched by sentiment analysis of users' comments. The main objective is based on defined metrics and characteristics that will be displayed. Subsequently, the data are analyzed using the proposed visualization in the application Kibana. The resulting data are interpreted, and there is designed a form of their distribution, which is the main objective of this work. The contribution of this work is the description of the processing of data that can be obtained from the website and public Facebook profiles with emphasis on their content, and their further enrichment and finally data visualization designed for wide range of audience.
