Based on the Web of Science, InCites database, this article will analyze the publication output of the Transcaucasia and Baltic states in computer science research field, their citations, as well as international collaboration in the field of computer science. The obtained results demonstrate that publications on computer science from the Baltic states are nearly 4 times higher than publications from Transcaucasia. Among the Baltic states, Lithuania holds a primary position followed by Estonia and Latvia; while in the Transcaucasia, the leading position is held by Azerbaijan, and followed by Armenia and Georgia. The same picture can be seen in the case of citations on the works on computer science of the studied states. In the international collaboration framework, the European states are the most frequent collaboration countries of the Baltic States. The same tendency can be seen in the case of Georgia and Armenia, while Azerbaijan shows a dramatically different vector of scientific internationalization.
