Relevance of a Set of Topical Texts to a Knowledge Unit and the Estimation of the Closeness of Linguistic Forms of Its Expression to a Semantic Pattern
Interrelated problems of completeness of knowledge extraction from a set (corpus) of subject-oriented texts are analyzed through the relevance to a source phrase and the search for the most rational linguistic...

The TF-IDF measure and analysis of links between words within N-grams in the formation of knowledge units for open tests
A method is proposed for searching in a text corpus for phrases that are the most similar to an original one in a described knowledge fragment (including linguistic forms of expression) based on a numerical ev...
