Mapping of physiotherapy techniques terminology in scientific databases
Novák, Michal ; Kučerová, Helena (advisor) ; Jarolímková, Adéla (referee)
in English This Bachelors thesis is dedicated to the major bibliographic databases in physiotherapy and mapping concepts between them. Firstly, based on the amount of important scientific journals, the most important bibliographic databases were identified and then they were analysed. That brought basic information about individual databases and about system how there are documents organised. These knowledge organisation systems were examined further with increased emphasis on concepts related to physiotherapy, especially physiotherapy techniques. Each concept was mapped across the analysed bibliographic databases and presented in a scheme, which can help to make information retrieval in those databases more efficient or as a principle for further investigation of those concepts and their relationship in medical bibliographic databases.

Pilecká, Věra ; Papík, Richard (advisor) ; Sedláčková, Beáta (referee) ; Rankov, Pavel (referee)
Mgr. Věra Pilecká The interaction of information science and cognitive sciences with emphasis on information retrieval (dissertation thesis) (Vzájemné ovlivňování informační vědy a kognitivních věd s důrazem na vyhledávání informací) Abstract Focus of this thesis is on the description of the interaction of information science and cognitive sciences with emphasis on information retrieval which is influenced by some of the cognitive aspects. The introductory chapter deals with the definition of information science and paradigms inspired by a cognitive approach (cognitive and socio-cognitive paradigm). Then a cognitive science is defined including its basis, methods and application. In the third chapter, a comparison between information and cognitive science is included, and their interaction and common interests are described. Fourth chapter focuses on information retrieval and influencing factors, including search methods, user information behaviour, and user cognitive characteristics and mental models. The final chapter presents two surveys focused on the use of intuitive and analytical information retrieval styles during searching on Google, and the perception of the differences between traditional and online teaching of the effective reading techniques. Both surveys illustrate the influence of users'...

Matching Images to Texts
Hajič, Jan ; Pecina, Pavel (advisor) ; Průša, Daniel (referee)
We build a joint multimodal model of text and images for automatically assigning illustrative images to journalistic articles. We approach the task as an unsupervised representation learning problem of finding a common representation that abstracts from individual modalities, inspired by multimodal Deep Boltzmann Machine of Srivastava and Salakhutdinov. We use state-of-the-art image content classification features obtained from the Convolutional Neural Network of Krizhevsky et al. as input "images" and entire documents instead of keywords as input texts. A deep learning and experiment management library Safire has been developed. We have not been able to create a successful retrieval system because of difficulties with training neural networks on the very sparse word observation. However, we have gained substantial understanding of the nature of these difficulties and thus are confident that we will be able to improve in future work.

Verification of the Kuhlthau's Information Search Process Model in the Environment of the Czech Republic
Přibylová, Ludmila ; Landová, Hana (advisor) ; Němečková, Lenka (referee)
The thesis focuses on Kuhlthau's Information Search Process Model. Firstly, the author explains Kuhlthau's model of information retrieval and seeking meaning of information from user's perspective. Results of the model are the uncertainty principle and mediation - findings which change our view of library services. In the second part of the thesis, the author introduces other research texts and manuals about writing a scientific text. She pays special attention to Jadwiga Šanderová's comprehensive manual which is called How to read and write a scientific text in social sciences, and to stylistics research text by Světla Čmejrková et al. called How to write down a scientific text. Thirdly, the author evaluates the survey which verifies Kuhlthau's model in the environment of the Czech Republic. The survey has taken place among postgraduate students, teachers and scientists from chosen universities in the Czech Republic

Internet searchings trends
Bjačková, Barbora ; Papík, Richard (advisor) ; Pilecká, Věra (referee)
Internet search has changed significantly since its beginning and it has also changed the way of information retrieval. Firstly, network search tools were created. However, greater development of internet search tools came after the creation of the Web. One of the first internet search tools were the web directories, such as Yahoo! or content directory Open Directory Project. Nowadays, web search engines are the most commonly used. Apart from general web search engines, there are also specialized or web search engines for particular aim or function, such as DuckDuckGo aimed at privacy, Yandex or Seznam.cz aimed at specific region or computational search engine WolframAlpha. Multimedia search and search adapted for mobile devices is technology trend in the field of internet search. Personalization, localization and social search belong among the contemporary trends. Semantic search is another long-lasting trend.

Syntax in methods for information retrieval
Straková, Jana
Title: Information Retrieval Using Syntax Information Author: Bc. Jana Kravalová Department: Institute of Formal and Applied Linguistics Supervisor: Mgr. Pavel Pecina, Ph.D. Supervisor's e-mail address: pecina@ufal.mff.cuni.cz Abstract: In the last years, application of language modeling in infor- mation retrieval has been studied quite extensively. Although language models of any type can be used with this approach, only traditional n-gram models based on surface word order have been employed and described in published experiments (often only unigram language models). The goal of this thesis is to design, implement, and evaluate (on Czech data) a method which would extend a language model with syntactic information, automatically obtained from documents and queries. We attempt to incorporate syntactic information into language models and experimentally compare this approach with uni- gram and bigram model based on surface word order. We also empirically compare methods for smoothing, stemming and lemmatization, effectiveness of using stopwords and pseudo relevance feedback. We perform a detailed ana- lysis of these retrieval methods and describe their performance in detail. Keywords: information retrieval, language modelling, depenency syntax, smo- othing

(English) The thesis examines the influence of information and communication technologies on the automation of library management processes and services as well as their applications, with a key consideration of the environment of the District Scientific Library of the city of Liberec. The introductory chapters briefly describe the development of basic international standards for data processing and communication networks in the world. The following chapters deal with the implementation of automated library management systems and networks in the Czech Republic in the early '90s, including accompanying projects that formed an inseparable part of the development. The development of automated library management processes and services in the District Research Library of the city of Liberec from the 90s till the end of 2010 becomes the core subject hereby examined. This is closely related to the parameters of the selection and application of the library management system, including the specific features thereof, as well as its internal utilization by librarians and its utilization by external users. The external use of the library management system has been evaluated through a survey of the use of online information sources and services sought by and provided to registered users. Taking into account the...
