Chomsky cannot help wondering at the fact that we, despite so vast evidence, have little knowledge about the obvious evidence. A good example, I think, is the child’s way of first language acquisition. A great many researchers have studied various aspects of child language acquisition at different stages of the child’ life and have brought to light many details of language development. However,...

We present a critique of language-based modelling for text input research, and propose an alternative inputbased approach. Current language-based statistical models are derived from large samples of text (corpora). However, this text reflects only the output, or final result, of the text input task. We argue that this weakens the utility of the model, because, (1) users’ language is typically q...

We investigate regular realizability (RR) problems, which are the problems of verifying whether intersection of a regular language – the input of the problem – and fixed language called filter is non-empty. We consider two kind of problems depending on representation of regular language. If a regular language on input is represented by a DFA, then we obtain (deterministic) regular realizability...
