PL Artykuł przedstawia koncepcję inteligentnego systemu poprawy błędów pisowni języka polskiego. System ma brać pod uwagę kontekst błędów, typ dokumentu oraz gramatykę i semantykę języka polskiego. Pewne elementy systemu bazują na rozwiązaniach wykorzystywanych w systemach już istniejących na Politechn[...]
EN The article presents a conception of an intelligent system for spelling correction in Polish language. The system should correct errors using the information of the document type and the context in terms of various aspects of grammar and semantics of Polish language. Certain elements of the system a[...]

EN Recent methods for learning word embeddings, like GloVe or Word2- Vec, succeeded in spatial representation of semantic and syntactic relations. We extend GloVe by introducing separate vectors for base form and grammatical form of a word, using morphosyntactic dictionary for this. This allows vectors[...]

EN In this paper, a novel neural network is proposed, which can automatically learn and recall contents from texts, and answer questions about the contents in either a large corpus or a short piece of text. The proposed neural network combines parse trees, semantic networks, and inference models. It co[...]

EN We present an efficient algorithm for scanning Huffman compressed texts. The algorithm parses the compressed text in O(n[(log2σ)/ b]) time, where n is the size of the compressed text in bytes, s is the size of the alphabet, and b is a user specified parameter. The method uses a variable size super-a[...]

PL W artykule przedstawiona została metoda automatycznej generacji listy skojarzeniowej dla danego wyrazu. Lista skojarzeniowa jest zbiorem wyrazów sematycznie związanych z wyrazem wejściowym. Podstawą metody jest wnioskowanie statystyczne. Dla generacji listy niezbędne są: słownik fleksyjny, korpus te[...]
EN In the paper we presents a method for automatic construction of an association list for a particular word. Association list is a set of word, each of which is in a semantic relation with the words, to define. To construct the association list we use statistic reasoning algorythm, which works on the [...]

EN The DCG rules are context-free rules with non-terminal symbols allowing arbitrary terms as parameters. Because of that the DCG-like formalisms are considered particularly well suited to encode NL grammars. This observation is however only partially true for languages withfree word and possibilities [...]
