Аннотация: Nowadays there is no common approach to summary. Manual evaluation is expensive and subjective and it is not applicable in real time or on a large corpus. Widely used approaches involve little human efforts and assume comparison with a set of reference summaries. We tried to overcome drawbacks of existing metrics such as ignoring redundant information, synonyms and sentence ordering. Our method combines edit distance, ROUGE-SU and trigrams similarity measure enriched by weights for different parts of speech and synonyms. Since nouns provide the most valuable information, each sentence is mapped into a set of nouns. If the normalized intersection of any pair is greater than a predefined threshold the sentences are penalized. Doing extracts there is no need to analyze sentence structure but sentence ordering is crucial. Sometimes it is impossible to compare sentence order with a gold standard. Therefore similarity between adjacent sentences may be used as a measure of text coherence. Chronological constraint violation should be penalized. Relevance score and readability assessment may be combined in the F-measure. In order to choose the best parameter values machine learning can be applied.
