Journal of Quantitative Linguistics is an international forum for the publication and discussion of research on the quantitative characteristics of language and text in an exact mathematical form. This approach, which is of growing interest, opens up important and exciting theoretical perspectives, as well as solutions for a wide range of practical problems such as machine learning or statistical parsing, by introducing into linguistics the methods and models of advanced scientific disciplines such as the natural sciences, economics, and psychology. Specifically, JQL publishes on: Observations and descriptions of all aspects of language and text phenomena including the areas of psycholinguistics, sociolinguistics, dialectology, pragmatics, etc. as far as they use quantitative mathematical methods (probability theory, stochastic processes, differential and difference equations, fuzzy logics and set theory, function theory etc.), on all levels of linguistic analysis. Applications of methods, models, or findings from quantitative linguistics to problems of natural language processing, machine translation, language teaching, documentation and information retrieval. Methodological problems of linguistic measurement, model construction, sampling and test theory. Epistemological issues such as explanation of language and text phenomena, contributions to theory construction, systems theory, philosophy of science.
