Problems solved by technology

[0004] Manual custom modeling is a modeling method that is input or selected by the user, so the disadvantage of this method is that it is completely dependent on the user and cannot accurately reflect the user's interest
The example modeling is to build a model by providing examples related or irrelevant to the user's interest. The disadvantage of this method is that the user needs to mark the page to get the example during the browsing process, which interferes with the user's normal browsing.
For automatic modeling, the model is automatically built according to the user's browsing behavior, and the example modeling technology is improved without causing interference to the user. However, the automatic modeling program implementation process is very complicated and is still far from perfect

Embodiment Construction

[0017] The specific implementation of the search method and device for the meta search engine provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Firstly, the specific implementation of the search method for a meta search engine in the present invention will be described in conjunction with the accompanying drawings.

[0019] attached figure 1 Shown is a schematic diagram of the implementation steps of this method, including: step S11, establishing a user interest model according to the pages browsed by the user; step S12, scheduling member search engines according to the user's query requirements and the user's interest model; step S13, according to The results are fused and sorted based on the relevance of the query results to the user's interests.

[0020] Wherein, step S11 further includes: analyzing the contents of the pages browsed by the user; and clustering the pages according to the analysis result...

Abstract

The invention discloses a search method for a meta search engine, comprising the following steps: building a user interest model according to a webpage browsed by the user; dispatching a member search engine according to the query requirement of the user and an interest model of the user; and according to the correlation degree of a query result and the user interest, fusing and sorting the result. The invention also provides a search device for a meta search engine. The method is a query result fusion method based on the user interest. By considering the user interest and the correlation degree of the user interest and the member search engine, the accuracy of the search engine can be improved without affecting the normal browsing process of the user.

Description

【Technical field】 [0001] The invention relates to the field of computer software, in particular to a search method and device for a meta search engine. 【Background technique】 [0002] How to let search engines actively understand user intentions, grasp user personalized information, and provide personalized services has become a research hotspot for many scholars in the field of information retrieval. In personalized information service, the analysis of user behavior, and then the establishment of user model has become the key technology of personalized service research. [0003] In the personalized meta search engine, there are mainly three ways to express the user model: topic representation, which expresses the user model with topics that the user is interested in; keyword representation, which represents the user model with keywords that the user is interested in, such as Web Watcher ; Based on the representation of the space vector model, the method of representing the...
