Embodiment Construction
[0020] A search engine hot word analysis algorithm described in this patent application consists of two parts: horizontal and vertical. The horizontal part processes the number of occurrences of words, expressed as where x 1 ≥1,x 2 ≥0, a>0, x 1 is the number of times a word appears in the closest period between two adjacent periods, x 2 is the number of times the word appears in the earlier period, a is the cardinality. The graph of this function is monotonically increasing.
[0021] for satisfies the condition x 1 ≥1, x2≥0, a>0, regardless of x 1 and x 2 How to change, the horizontal part can calculate the result. If the word did not appear in an earlier cycle, it is a new word that appeared in a more recent cycle, by There will be no situation where the calculation result cannot be obtained because the denominator is 0, so that the situation that the effective word has no calculation result can be avoided.

The invention discloses a search engine hot word analytical algorithm which is composed of a transverse part and a longitudinal part. The transverse part is used for processing the number of search times of words in two adjacent cycles and is shown as (x1+a) / (x1+x2+2a), wherein x1 is the number of times of the words occurring in the recent cycle, x2 is the number of times of the words occurring in the early cycle, and a is a cardinality number larger than 0. The longitudinal part selects a function to process a balance factor M, wherein the function has the monotone increasing character, and the function value of the function in a zone larger than 0 is larger than 0. M can be the number of unrepeated IPs or the number of unrepeated radiuses or the number of user identification cards of internet users who search the words. The result of the horizontal part is multiplied by the result of the longitudinal part, and a final hot word analyzing result can be obtained. By means of the search engine hot word analytical algorithm, the validity and reliability of the search engine hot word scoring algorithm can be obviously improved, the anti-interference capability of the algorithm is improved, and therefore the rational result high in availability is obtained.
Description
technical field [0001] The application belongs to the field of information technology, and relates to a search engine hot word analysis algorithm. Background technique [0002] Hot words refer to words that have been searched by a large number of Internet users through search engines within a certain period of time. Compared with non-hot words, hot words have a higher number of searches. Generally, hot words can be obtained by processing the number of occurrences of words in two adjacent periods through a series of methods, and filtering the processing results. The processed result is called keyword score, and the processing method is called keyword score algorithm. [0003] The existing keyword scoring algorithm is to subtract the number of times the term was searched in the earlier period from the number of times the term was searched in the recent period, and then divide it by a base number, which can be the number of times the term was searched in the recent period The...
