Method and system for calculating retrieval precision of internet keyword

InactiveCN106560808AReduce precisionRetrieval accuracy score is smallSpecial data processing applicationsThe InternetSecond hit
The invention discloses a method and system for calculating retrieval precision of an internet keyword, and relates to the field of internet keyword retrieval. The method comprises the first step of adding up clicks of each retrieval result corresponding to a keyword of which retrieval precision needs to calculated; the second step of selecting in order three retrieval result groups, namely, a first hit retrieval result group, a second hit retrieval result group and a third hit retrieval result group in the descending order of the clicks of all the retrieval results, wherein the number of the retrieval results of each retrieval result group is at least 10 and all the retrieval results which are not selected serve as a non-hit retrieval result group; the third step of calculating a grade S of the retrieval precision of a current keyword. According to the method and system for calculating the retrieval precision of the internet keyword, the grade of the calculated retrieval precision is identical with the practical retrieval precision, the result of the grade of the retrieval precision is very accurate, thus accurate data are provided for development of a secondary statistics of a search platform, and the applicability of the method and system is very strong.
