The paper considers bibliometric indicators NLP and ML. Dynamic indicators are evaluated and areas of research with the highest...
Article
Full-text available
Исследуется возможность установления смысловой близости научных текстов методом их автоматической классификации, основанным на сжатии аннотаций. Идея метода состоит в том, что алгоритмы компрессии типа PPM (prediction by partial matching) сжимают терминологически близкие тексты существенно лучше, чем далекие. Если для каждой классифицируемой темати...
