Abstract: The invention constructs Chinese readability model with data reduction and smart/advanced artificial intelligence algorithm. The model contains 1) a word segmentation which segments words and tags the part of speech of the words. 2) a readability indicator unit which analyzes readability features based the segmented words segmentation and part of speech tagging; and 3) an evolution algorithm unit, which construct a Chinese text readability model using data reduction approach and smart/advanced artificial intelligence algorithm. The present invention assesses the readability of Chinese texts, based on a small amount of Chinese text, and identifies the adequate readers.
