Vector spaces for historical linguistics : using distributional semantics to study syntactic productivity in diachrony

This paper describes an application of dis- tributional semantics to the study of syn- tactic productivity in diachrony, i.e., the property of grammatical constructions to attract new lexical items over time. By providing an empirical measure of seman- tic similarity between words derived from lexical co-occurrences, distributional se- mantics not only reliably captures how the verbs in the distribution of a construc- tion are related, but also enables the use of visualization techniques and statistical modeling to analyze the semantic develop- ment of a construction over time and iden- tify the semantic determinants of syntactic productivity in naturally occurring data

Grigori Kuzmin and Stellar Dynamics

Grigori Kuzmin was a very gifted dynamicist and one of the towering figures in the distinguished history of the Tartu Observatory. He obtained a number of important results in relative isolation which were later rediscovered in the West. This work laid the foundation for further advances in the theory of stellar systems in dynamical equilibrium, thereby substantially increasing our understanding of galaxy dynamics.Comment: 10 pages, 1 figure, to appear in Baltic Astronomy, proceedings of the conference "Expanding the Universe" held in Tartu, Estonia, 27-29 April, 201
