Problems solved by technology

[0005] 1. The interaction between users is not considered, and the similarity is only calculated from the perspective of examples;
[0006] 2. It does not consider the variability of user interests and cannot track the latest needs of users

Embodiment 1

[0035] Example 1: Taking the real log data of Peking University Library from January 2008 to June 2008 as an example, combined with figure 1 The domain ontology schematic diagram describes the specific implementation of the present invention in detail.

[0036]This specific embodiment describes a method for providing personalized search services for library users. The goal is that different users can get the information that is closest to their needs for the retrieval request of the same keyword, so as to bring better user experience to users. In this specific embodiment, the system structure of the personalized search method based on book domain ontology is as follows: figure 2 shown.

[0037] The specific description is as follows:

[0038] The first part, the offline part. The offline part of the work is done offline, that is, before the user submits the keyword search. The specific steps are as follows:

[0039] Step 1. Establish domain ontology: use a specific doma...

Abstract

The invention provides an individuation searching method based on book domain ontology, belonging to an individuation network searching service. The individuation searching method comprises the following steps of: establishing the domain ontology, introducing a collaborative filtering idea, and adding semantic relationships which present influences among users; analyzing and processing logs and establishing a user model based on user interests and preferences; computing individuation scoring through spreading Activation (SA) based on the user model and the domain ontology; in addition, rearranging searched results, rearranging the results returned by a primary search engine according to an individuation scoring sequence from high to low, and returning to the users. Through introducing the collaborative filtering idea into the domain ontology, establishing the user model which presents user interest changes timely, and analyzing user requirements accurately by the SA, the invention effectively eradicates ambiguity of key words and greatly improves satisfaction degree of the users on the searched results.

Description

technical field [0001] The invention relates to personalized services of libraries, in particular to a method for providing personalized searches for libraries, and belongs to the technical field of computer application technology information management. Background technique [0002] In the information age, with the explosive increase in the amount of information, "information overload" has gradually become a problem that cannot be ignored. General search engines, such as Google and Baidu, can return thousands of search results, but this brings difficulty in information screening for users. Moreover, users often submit some ambiguous keywords. For example, user A who likes thrillers uses the keyword "Da Vinci" to search for Dan Brown's masterpiece "Da Vinci's Code", while user A who is keen on Renaissance art B also selects the keyword "Da Vinci" to search for Da Vinci's paintings. Obviously they have different information needs, but Google and Baidu will return them the s...
