Abstract

The embodiment of the invention provides a machine learning model and an establishing method thereof. The method comprises the following steps of: a1, acquiring a sample library of conventional target words; a2, performing positive and negative sample classification on the conventional target words for classifying the conventional target words into at least one positive sample and at least one negative sample; a3, performing feature extraction on the positive sample and the negative sample; and a4, forming the machine learning model according to the extracted features of the positive sample and the negative sample. In the method of the embodiment of the invention, the machine learning model is established by performing classified and graded statistics on conventional search keywords and advertising auction words, so as to automatically identify, analyze and evaluate new keywords or auction words by a machine; and therefore, a classified and graded method and a classified and graded system for the target words are realized.

Description

【Technical field】 [0001] The present invention relates to a machine learning model and its establishment method, in particular to a machine learning model such as keywords and / or advertisement words and its establishment method. 【Background technique】 [0002] In every corner of the online world and the real world, the popularity and importance of advertising is increasing day by day. A lot of advertisement words have thus been produced, and similar target words such as search words, keywords or auction words also appear on the Internet. However, for newly emerging advertising words, it is generally only possible to subjectively judge whether it has a positive effect and what level of effect it can achieve by relying on human resources. But for some inexperienced people, it is easy to make wrong judgments. Moreover, it is difficult to make large-scale judgments manually, and at the same time, it is difficult to guarantee the consistency of subjective judgments. How to aut...
