Problems solved by technology

[0004] However, existing keyword recommendation methods only consider the semantic correlation between keywords and query words, and do not consider customers' consumption intentions. For example, although the semantic correlation between some recommended keywords and query words higher, but the attributes of these keywords do not meet the customer's willingness to consume, and these keywords will not be purchased by customers, which wastes recommendation resources. Recommended resources are reduced, and the success rate of recommendation is reduced

[0049] Step 101: Obtain the customer's query words.

[0050] The query word is usually the query word entered by the customer when logging into the keyword recommendation system.

[0051] Step 102: Search keywords whose semantic correlation with the query term meets the preset correlation requirement from the candidate keyword database, and select the top N keywords with semantic correlation, where N is a preset positive integer.

[0052] In this step, an existing semantic correlation calculation method may be used to calculate the semantic correlation between keywords in the candidate keyword database and the query word. For example, the following method can be selected: after word segmentation processing is performed on keywords and query words, respectively, based on the inverse document frequency (IDF) o...

Embodiment 2

[0087] figure 2 The device structure diagram provided for the second embodiment of the present invention, such as figure 2 As shown, the keyword recommendation device may include: a query word acquisition unit 200 , a willingness determination unit 210 and a keyword recommendation unit 220 .

[0088] The query term acquiring unit 200 acquires the customer's query term.

[0089] The query word is usually the query word entered by the customer when logging into the keyword recommendation system.

[0090] The willingness determining unit 210 classifies the customers by using a classifier trained in advance from the samples of the customers' willingness to consume, and determines the willingness to consume of the customers.

[0091] The sample of customer consumption intention can be selected from the customer consumption data of known consumption intention, and the customer's consumption intention can include but not limited to: bidding information of purchasing keywords, geo...
