Named Entity Disambiguation in Slovak
Križan, Samuel ; Otrusina, Lubomír (referee) ; Smrž, Pavel (advisor)
Thesis deals with the topic of named entity recognition and disambiguation. A basic system was created which includes all prequisitions necessary for named entity disambiguation in Slovak language. Part of the system is building of a knowledge base out of an export from Slovak Wikipedia. This was subsequently compared to knowledge base obtained from Wikidata, which revealed that the main contribution of Wikipedia knowledge base for Slovak language is greater coverage of entities with link to Slovak Wikipedia and better determination of entity classes. Apart from that, morfological dictionary of KNOT@FIT research group was updated, which yielded an improvement by 33-39 %. This work presumes possible utilization in relation to system extention by a disambiguation modul and enhancement of alternative names coverage.

Creating a knowledge base for insurance products
Pokorný, David ; Štrof, Jan (referee) ; Jirsík, Václav (advisor)
This bachelor thesis is about developing a knowledge base for an expert system. Knowledge base is a set of appropriately coded knowledge from the areas of human activities, which can be expressed with some uncertainty. This created knowledge base is used for qualified selection of appropriate risk life insurance. Base is being create in cooperation with financially – advisory company and will be deployed in regular service where it will help Sales representatives in their regular expert work. Theoretical part of the document describes problematics of creation and tuning of a knowledge base, there is also described a wide range of usage expert system aplications and illustration of NPS expert system and its syntax. Practical part then consists of description of development knowledge base, evaluation of the final results and proposals for another development.

Machine Comprehension Using Commonsense Knowledge
Daniš, Tomáš ; Landini, Federico Nicolás (referee) ; Fajčík, Martin (advisor)
V tejto práci je skumaná schopnosť používať zdravý rozum v moderných systémoch založených na neurónových sieťach. Zdravým rozumom je myslená schopnosť extrahovať z textu fakty, ktoré nie sú priamo spomenuté, ale implikuje ich situácia v texte. Cieľom práce je poskytnúť náhľad na súčasný stav výskumu v tejto oblasti a nájsť sľubné výskumné smery do budúcnosti. V práci je implementovaný jeden z najmodernejších modelov na odpovedanie na otázky a je ďalej použitý na experimenty v rôznych situáciách. Narozdiel od starších prístupov, tento model dosahuje porovnateľné výsledky s najlepšími známymi modelmi aj keď jeho architektúra neobsahuje žiadne prvky zamerané konkrétne na zlepšenie schopnosti zdravo uvažovať. Taktiež boli nájdené štatistické artefakty v populárnej sade dát s otázkami vyžadujúcimi zdravé uvažovanie. Tieto artefakty môžu byť použité štatistickými modelmi na nájdenie správnej odpovede aj v prípadoch, kedy by to nemalo byť možné. Na základe týchto zistení sú v práci poskytnuté odporúčania a návrhy pre výskum do budúcnosti.

Analysis of helpdesk system requirements in company dealing with development of information systems and outsourcing of payroll and human resources
PEROUTKA, David
The topic of this diploma thesis is focused on the analysis of the company's requirements for the selection of a system to support communication with customers - helpdesk. The beginning of the work is devoted to theoretical basics of helpdesk systems such as trouble ticket life cycle or knowledge base system. Furthermore, the use of the helpdesk system is described from the point of view of usage and then from the point of view of the roles that occur when using this system. At the end of the theoretical part are described ECS systems, which the helpdesk system is part of. The practical part describes the company for which this work is processed and its functional requirements for the selected system and systems directly related to it. In addition, 4 available solutions are selected, which include their pros and cons and then are evaluated based on seven criteria. The best solution is recommended to the company for selection. In the end of the work, the course of implementation of the solution chosen by the company is outlined.

Semantic Enrichment Component
Doležal, Jan ; Otrusina, Lubomír (referee) ; Dytrych, Jaroslav (advisor)
This master's thesis describes Semantic Enrichment Component (SEC), that searches entities (e.g., persons or places) in the input text document and returns information about them. The goals of this component are to create a single interface for named entity recognition tools, to enable parallel document processing, to save memory while using the knowledge base, and to speed up access to its content. To achieve these goals, the output of the named entity recognition tools in the text was specified, the tool for storing the preprocessed knowledge base into the shared memory was implemented, and the client-server scheme was used to create the component.

System for Update of Annotations in Corpora
Vrša, Štěpán ; Smrž, Pavel (referee) ; Dytrych, Jaroslav (advisor)
The goal of this thesis is the creation of a system that allows users to display and update the large corpus data annotations in the MG4J format. This thesis analyzes the current corpus data and annotation management solution and briefly describes the non-trivial SEC and MG4J tools used in the solution. The main element of the system is updating annotations in MG4J and subsequently updating the MG4J indexes. The system is capable of performing the above mentioned operations with an acceptable response time. This thesis also deals with updating entities in a knowledge base.
