Abstract

A method of generating content information that matches at least one stored keyword is described. At least one keyword associated with content information is stored. At least one previously searched keyword in a search record is matched with the at least one stored keyword associated with the content information. First-category mapping data is generated based on a first mapping between the matched at least one stored keyword and the at least one previously searched keyword. Second-category mapping data is generated based on the content information and the at least one stored keyword. A received target keyword is determined to be included in the first-category mapping data. In response to the received target keyword, which is included in the first-category mapping data, circuitry of a terminal searches for the content information associated with the target keyword in the second-category mapping data and displays the content information.

First claim

What is claimed is:

1. An information processing method, comprising:
matching at least one previously searched keyword of a plurality of previously searched keywords in a search record with a predetermined keyword based on determined degrees of similarity between the predetermined keyword and the plurality of previously searched keywords, the predetermined keyword being predetermined as associated with promotion content information in response to a request from a promotion user that is an advertisement promoter;
generating first-category mapping data that indicates a first mapping between the predetermined keyword and the at least one previously searched keyword determined based on the degrees of similarity between the predetermined keyword and the plurality of previously searched keywords;
storing second-category mapping data that indicates the association between the promotion content information and the predetermined keyword;
after the first-category mapping data is generated, determining whether a received target keyword entered by a search user is one of the at least one previously searched keyword that was mapped to the predetermined keyword in the first-category mapping data; and
in response to receiving the target keyword entered by the search user and the received target keyword being determined to be one of the at least one previously searched keyword mapped to the predetermined keyword in the first-category mapping data,
identifying, by circuitry of an information processing apparatus, the predetermined keyword mapped in the first-category mapping data to the one of the at least one previously searched keyword that is the same as the target keyword entered by the search user,
determining, by the circuitry of the information processing apparatus, the promotion content information associated with the predetermined keyword mapped to the one of the at least one previously searched keyword that is the target keyword based on the second-category mapping data,
obtaining a feedback evaluation value of the promotion content information and filtering the promotion content information based on the feedback evaluation value and a feedback threshold, the feedback evaluation value being obtained through calculation by using hits, an applause rate, and/or a poor rating rate, and
displaying the promotion content information based on the filtering,

wherein the matching the at least one previously searched keyword comprises
traversing the at least one previously searched keyword in the search record;
searching the predetermined keyword and the at least one previously searched keyword in a third-party search engine;
calculating, by using a document vector model, a degree of similarity between a search result corresponding to the predetermined keyword and a search result corresponding to each of the at least one previously searched keyword; and
when the degree of similarity between the search result corresponding to the predetermined keyword and the search result corresponding to a respective one of the at least one previously searched keyword is greater than a similarity threshold, determining that the respective one of the at least one previously searched keyword matches the predetermined keyword.

2. The information processing method according to claim 1 , wherein after the generating the first-category mapping data, the method further comprises:
grouping the predetermined keyword and one or more other predetermined keywords into a group based on at least one corresponding meaning of the predetermined keyword and the one or more other predetermined keywords, the one or more other predetermined keywords being predetermined as associated with other promotion content information;
establishing a second mapping between the at least one previously searched keyword and one of the one or more other predetermined keywords in the group; and
updating the first-category mapping data to further indicate the second mapping.

3. The information processing method according to claim 1 , wherein after the generating the first-category mapping data, the method further comprises:
grouping the at least one previously searched keyword and one or more other previously searched keywords in the search record into a group based on at least one corresponding meaning of the at least one previously searched keyword and the one or more other previously searched keywords;
establishing a second mapping between the predetermined keyword and one of the one or more other previously searched keywords in the group; and
updating the first-category mapping data to further indicate the second mapping.

4. The information processing method according to claim 1 , further comprising:
identifying target promotion content information that is included in the second-category mapping data;
searching for an extended keyword in an access record of associated information corresponding to the target promotion content information;
establishing a second mapping between the target promotion content information and the extended keyword; and
updating the second-category mapping data to further indicate the second mapping.

5. The information processing method according to claim 4 , wherein the searching for the extended keyword comprises:
obtaining the associated information corresponding to the target promotion content information based on a topic model or a document vector model; and
searching for a second previously searched keyword included in the access record of the associated information, and using the second previously searched keyword as the extended keyword corresponding to the target promotion content information.

6. The information processing method according to claim 1 , wherein
the first-category mapping data includes a first matching degree between the at least one previously searched keyword and the predetermined keyword;
the second-category mapping data includes a second matching degree between the predetermined keyword and the promotion content information; and
the method further includes calculating a similarity between the predetermined keyword and the promotion content information in the second-category mapping data by using a document vector model, and using the similarity as the second matching degree.

7. The information processing method according to claim 6 , wherein before the displaying the promotion content information, the method further comprises:
obtaining a content information matching degree between the target keyword and the promotion content information according to the first matching degree and the second matching degree; and
sorting and filtering the promotion content information according to the content information matching degree, and displaying the sorted and filtered promotion content information.

8. The information processing method according to claim 7 , further comprising:
searching the target keyword in a search engine to obtain a search result and a search matching degree between the search result and the target keyword; and
shuffling the search result and the promotion content information with reference to the search matching degree and the content information matching degree, and displaying the shuffled search result and the promotion content information.

9. The information processing method according to claim 8 , wherein the shuffling the search result and the promotion content information further comprises:
normalizing the search matching degree of the search result and the content information matching degree of the promotion content information to a corresponding threshold interval to obtain a normalized recommendation level value; and
sorting the search result and the promotion content information according
