This thesis aims to investigate the visualization approaches in the field of annotated discourse relations and to find a solution that meets the requirements best by comparing different programming tools. The subject of this research are coherence relations, which have several properties that can be challenging for many visualization methods. The thesis presents five different visualization options from both the application and the development perspective. The initially tested simple HTML approaches as well as the software package displaCy show the insufficient level for the visualization purposes of this work. The alternative implementation with D3 would optimally meet the requirements but goes beyond the scope of the project. The main method chosen in this thesis was implemented as a single web application and uses the brat annotation tool, which fulfills most of the defined requirements for the representation of the coherence relations. The application graphically displays the coherence relations annotated in the text and offers a filter function for different relation types.
It was not until the 1960s and 70s of the 20th century that researchers turned their special interest to colloquial Russian (hereafter CR) and its interaction with codified (normative) Russian. Colloquial Russian uses its grammatical constructions in deviation from the norms of the written language. Since codified language is the basis of colloquial language on the grammatical level, among others, the question arises, how the standard forms are used in oral speech. Lapteva (1976) has looked in particular at the syntax of CR and made a classification of CR constructions that differ from their standard forms. The present study deals with two constructions from this classification: an embedded temporal subordinate clause and a temporal subordinate clause with the meaningless conjunction kogda (as/if), which leaves its normative position in the sentence. In addition to the special forms of temporal adverbial clauses, the frequency of their standard implementation as preceding and the following constructions will be examined. Two hypotheses were formulated:
• The frequency of certain constructions classified by Lapteva (1976) as transitional constructions decreases over decades.
• The ratio between prefixed and suffixed temporal subordinate clauses will be in favor of the latter due to the spontaneity of oral speech. The corpus study was conducted with the oral language sub-corpus of the National'nyj Korpus Russkogo Jazyka (National Corpus of the Russian Language). No evidence of a correlation between the number of CR constructions and the year of recording was found either in the whole oral sub-corpus or in its largest section - the collection of private conversations. The proportion of prefixed temporal constructions was greatest in both public and non-public corpora compared to postfixed ones. The study did not provide evidence for the hypotheses put forward, due to the limitations of the corpus study, such as missing or incomplete context of the conversations, lack of punctuation and/or marking of intonation.
