Semantic information from FrameNet and the possibility of its transfer to Czech data
Limburská, Adéla ; Lopatková, Markéta (advisor) ; Holub, Martin (referee)
The thesis focuses on transferring FrameNet annotation from English to Czech and the possibilities of using the resulting data for automatic frame prediction in Czech. The first part, annotation transfer, has been performed in two ways. First, a parallel corpus of English sentences and their human created Czech translations (PCEDT) was used. Second, a much larger parallel corpus was created using ma- chine translation of FrameNet example sentences. This corpus was then used to transfer the annotation as well. The resulting data were partially evaluated and some of the automatically detectable errors were filtered out. Subsequently, the data were used as an input for two machine learning methods, decision trees and support vector machines. Since neither of the machine learning experiments brought impressive results, further manual correction of the data annotation was performed, which helped increase the accuracy of the prediction. However, as the accuracy reported in related papers is notably higher, the thesis also discusses dif- ferent approaches to feature selection and the possibility of further improvement of the prediction results using these methods. 1

Charles Fillmore - from Case Grammar to Frame Semantics
Limburská, Adéla ; Lehečková, Eva (advisor) ; Synková, Pavlína (referee)
Charles Fillmore (1929-2014) was an American linguist who, at the beginning of his career, formulated the case grammar theory, which was based on the assumptions made by generative grammar. Subsequently, however, he started to criticize generativist account of semantics and accepted some premises of the cognitive approach. As a result of this progress, Fillmore proposed the frame semantics theory, which was later used to develop the FrameNet lexical database. This thesis follows the gradual change of Fillmore's linguistic approach, investigates its causes and illustrates the method on selected case studies. It also shows the practical application of Fillmore's current theory in the FrameNet database. Moreover, the thesis shows in which aspects Fillmore's linguistic model might enhance further linguistic research, and introduces several approaches and projects inspired by Fillmore's thoughts.
