Embodiment Construction

[0035] The digital book search method based on user click behavior includes the following steps:

[0036] 1. Extract the book reading records in the log to construct the correlation graph between the books, and use the correlation graph to calculate the correlation ranking score of the books

[0037] Suppose the set of readers is: U={u i : 0≤ij : 0≤ji，j :u i ∈U∧b j ∈B, 0≤ii，j is a bool value, if the reader u i read the book b j More than 20% of the pages, it is regarded as an effective reading behavior, t i，j Equal to True, otherwise it is considered that the reading behavior has not occurred, t i，j Equal to False:

[0038]

[0039] There is an association relationship between books, and the present invention associates the two books through readers who have read the two books at the same time. definition U i , j ⊆ U , It is a subset of U, indicating that the bo...

Abstract

The invention discloses a method for digital book searching based on the clicking behavior of the user. Firstly, the book reading records in a Web log are extracted to construct an association diagram between the books, and the relativity ordering of the books is calculated with the association diagram; secondly, the searched reading records in the log are extracted, to classify the inquiry wordsaccording to the hidden feedback of readers on the search results; finally, based on the classification of the inquiry words, for each type of inquiry words, the hidden feedback of the readers on thesearch results is used to form the final book search result ordering by integrating with through information sources, namely obtaining the book relativity ordering from the association diagram, book comments from the internet and test similarity. The method can obtain objective book relativity ordering and good word category inquiry effect; the rich book comment data on the internet is integratedinto a relatively closed and static digital library, so as to effectively improve the book searching quality.

Description

technical field [0001] The invention relates to the fields of digital library, information retrieval and Web usage mining, in particular to a digital book search method based on user click behavior. Background technique [0002] The 21st century is the era of digitization. With the rapid development of computer technology, mass storage technology and network technology, the digitization of information carriers and the networking of information dissemination have been deepened unprecedentedly, and the digitization of libraries has become an inevitable trend. Digital library has received high attention in many countries in the world and has achieved rapid development. It has become an important way for people to obtain information and knowledge. [0003] Digital libraries usually have a large number of digital book resources, how to effectively use these rich and valuable resources, so that digital library readers can make full use of them is very important. Digital book sear...
