چکیده
Elena BORISSOVA Institut Russkogo yazyka imP~shkina Moscow Abstract This paper presents a computer-tool teaching system supplied by a language processor. Its aim is to correct mistakes in texts written by foreign students learning Russian as a second language. Since a text may include grammar mistakes, the system cannot use morphological analysis to fool extent. So one must compile a programm capable of finding and correcting mistakes without traditional means of analysis. To solve this problem we prepone a system that includes a vocabalary and rules of finding and re-writing words. So the process consists of finding word stems and than correcting word endings . Semantic and syntactic information("a model of ruling"/Mel'~uk 1974/~ necessary for that is written in the vocabulary of verbs as a frame. The slots of this frame contain semantic and morphological information about words that depend on this vord~. The vocabulary containing now approximately 200 lexemes is enough for beginners

متن کاملDemonstration of interactive teaching for end-to-end dialog control with hybrid code networks
This is a demonstration of interactive teaching for practical end-to-end dialog systems driven by a recurrent neural network. In this approach, a developer teaches the network by interacting with the system and providing on-the-spot corrections. Once a system is deployed, a developer can also correct mistakes in logged dialogs. This demonstration shows both of these teaching methods applied to ...
