Automatic document summarization based on statistical information

Abstract

Actual problem in nowadays is to efficiently process the large amount of data that pass through
our mind everyday. The object of study of this paper is automatic summarization algorithms.
The main goal is to implement and make comparison of different summarization techniques
on corpora of news articles parsed from the web. This research work contains the description
of three summarization techniques based on TextRank algorithm: General TextRank, BM25,
LongestCommonSubstring. It is specially noted the languages of used corpora: Russian and Kazakh
languages. The results of summarization processes and their comparison are provided. It should
be emphasized that used algorithms are well-known, but the way of their evaluation on defined
corpora is different from those which usually used in summary evaluation. The method of summary
evaluation proposed use the special dictionary of extracted key-words on the topic of corpora. As
the title implies the article describes applying statistical information. The semantic and syntactic
features of text are not examined.
