Embodiment 1

[0045] figure 1 It is a flow chart of a method for constructing a book knowledge map provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of constructing a book knowledge map for recommending books to users. The knowledge map construction device can be implemented, and the device can be implemented by software and / or hardware, and can generally be integrated in a device with certain computing capabilities, such as a terminal or a server. Such as figure 1 As shown, the method specifically includes the following operations:

[0046] S110. Obtain abstract corpus corresponding to at least two books respectively.

[0047] Among them, the abstract corpus is a semantically coherent essay that concisely and accurately describes the main content of the book. Generally speaking, when the Internet collects an electronic book, it will correspondingly include the abstract corpus corresponding to the book, and the abstract corpus is used for users ...

Embodiment 2

[0071] figure 2 It is a flow chart of a method for constructing a book knowledge map in Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. In this embodiment, entity recognition will be performed based on the abstract corpus corresponding to the book , specifically: input the abstract corpus corresponding to the book into at least one entity recognition model for entity recognition, and obtain an entity matching the entity recognition model; and,

[0072] After inputting the abstract corpus corresponding to the book into at least one entity recognition model for entity recognition, and obtaining an entity matching the entity recognition model, it also specifically includes: if the recognized entity includes at least two data forms, then According to the mapping relationship between entities of different data forms, the obtained entities of at least two data forms are converted into entities of the same data form...

Embodiment 3

[0099] image 3 It is a flow chart of a method for constructing a book knowledge graph in Embodiment 3 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. In this embodiment, entities and books will be established based on the identified entities.

Abstract

The embodiment of the invention discloses a book knowledge graph construction method and device, a book recommendation method and device, computer equipment and a storage medium. The book recommendation method comprises the steps that abstract corpora corresponding to at least two books are acquired; entity identification is carried out according to abstract corpora corresponding to the books; anentity and book association table is established according to the identified entities; according to the entity and book association table, the book knowledge graph is constructed. According to the technical scheme provided by the embodiment of the invention, a new mode of constructing the book knowledge map according to the association degree between each entity and each book and recommending thebooks based on the book knowledge map is provided, the existing book recommendation technology is optimized, and the increasing personalized and convenient book reading requirements of people are met.

Description

technical field [0001] Embodiments of the present invention relate to data processing technology, and in particular to a construction of a book knowledge map, a book recommendation method, device, computer equipment, and storage medium. Background technique [0002] At present, with the popularity of mobile terminals such as mobile phones and the development of e-book readers, e-books are becoming more and more popular among readers. Today's reading apps (applications) will recommend some best-selling books or books with high praise rates on the main interface for users to choose to read. However, best-selling books or books with higher praise rates are not necessarily the ones that users like. [0003] With the continuous improvement of technology, people's requirements for book recommendation technology are also constantly improving, and the existing book recommendation technology can no longer meet people's growing demand for personalized and convenient book reading. C...
