Effects of part of speech, word category and word frequency on difficulty and reaction time of Chinese Words Reasoning Test;

To design a text-filter experiment, first, the dualistic relevancy of word coexistence frequency should be mined by the word frequency Stat.

Combining with algorithms of statistical word frequency and channels,forgetting algorithm and documents attention algorithm,it can obtain the changes of users interests dynamically and satisfy the regquirement of personalized search.

Points out the limitations of general text feature extraction method based on TfIdf in problems of text classification,and presents the standpoint that combines the term distribution characteristic,term frequency and document frequency to extract the text feature,thus giving a new method to compute term s weight,and a new way of text classification.

The techniques used in the method are discussed,which include selecting the characters of text doc-uments,the constructing the character lexicons as well as the computation of the weights of the term frequency(TF).

They ignore that the term frequency results in the classifier\'s capacity of classification down.

The Affects of Category Size and Frequency on Subliminal Semantic Activation;

There is a significant correlation between frequency and word gain in the multiple - choice test, but not in the blank - filling test.

What role do word frequency and predictability play in the process of words recognition? Do word frequency and predictability affect the same stage of words recognition? Do word frequency and predictability have an interaction relationship? Many studies have been carried out to explore these questions in alphabetic languages.
