AUTOMATED MODELING OF ROMANIAN LITERARY TRENDS IN HISTORY USING TOPICS OVER TIME AND CO-OCCURENCES Authors: Neagu Laurentiu-Marian, Trausan-Matu Stefan, Dascalu Mihai, Simion Eugen, CHISU Lucian Volume 1 | DOI: 10.12753/2066-026X-20-019 | Pages: 151-158 | Download PDF | Abstract
The Chronology of Romanian Literary Life (also referred to as CVLR) is an ambitious effort conducted by the "G. C?linescu" Institute of Literary History and Theory to present the most important literature-related events from Romania, covering a period of 50 years, starting with World War II up until the beginning of the 3rd century. Our work aims to capture the evolution of trends in the Romanian literary space using a custom LDA topic model, focused also on the changes in the structure of topics across time, as well as the relations between the topics. In the Trends Over Time approach, the discovery of topics is related not only to the co-occurrences of words, but also to the timestamps associated to events (temporal information). Our results depicting the dynamics of trends over time are interesting both from an e-learning perspective, but also from literary and historical perspectives. Patterns of co-occurrences are discovered and visualizations of the topics' evolution in time are introduced to provide valuable insights from CVLR. Moreover, topic entropy is used to assess the diversity of ideas covered by a topic. The obtained results are promising, reflecting the most important historical periods and the evolution of trends in a coherent manner in relation to the historical events. By showing trends dynamics over time is interesting both from an eLearning perspective and from Literary and Historical perspective. Our study represents a solid foundation for further analyses on Romanian literary events by relying on automated models grounded in advanced Natural Language Processing techniques. | Keywords
