Complex Networks-based Approach to Russian Rhyme History Description: Linguostatistics and Database
Fundamental and Computational Linguistics
The paper is devoted to the graph analysis for Russian rhyme research. The aim of the paper was to apply this method to the investigation of rhyme diachrony and to the information search using graph metrics and visualization. In order to achieve the aim the following tasks were set: extract and classify rhymes from the poetic corpus of the Russian national corpus, build a graph database, prove the consistency of the method using statistical database analysis and the previous rhyme research, discover new features using mathematical and visual techniques of the graph analysis. The work resulted in tables of rhymes from the 18th century till the first third of the 20th century, including detailed classification; graph database, convenient for advanced search; five dynamic network visualizations; detailed analysis of various quantitative network features. Network analysis of the Russian rhymes revealed non-trivial results, among which is similarity in some respects between the networks of the 18th century and the first third of the 20th century, peak values of some numerical features in the network of the first third of the 19th century. These results can be interpreted as a sign of instability of the rhyme systems in the first two epochs listed, and consistency, intensity of the classic tradition of the last epoch described.
