Lecture
The tasks of text analysis are formulated (stages of text analysis,
medium text processing, task text mining). The stages of analysis are considered.
texts, such as extracting key concepts from the text (general description of the process
extraction of concepts from the text, the stage of local analysis, the stage of integration and
notion of concepts), the classification of text documents (description of the tasks of the classification
texts, methods for classifying text documents), clustering methods
text documents (text document guidance, hierarchical
text clustering methods, binary text clustering methods),
texts (performing annotation of texts, methods for extracting fragments for
annotations). Various text analysis tools are compared.
