Embodiment 1

[0080] Such as figure 1 As described, the document recommendation method in this embodiment includes:

[0081] S110, acquiring the original document.

[0082] Among them, the original document includes a title and a text, and the topic information can be extracted from the title, that is, the field to which the original document belongs, such as science and technology, finance, military, etc., and the focus information can be extracted from the text, such as keywords, named entities, etc.

[0083] In one embodiment, the original document may include the document being clicked by the user, and may also include the document involved in the user's click log, wherein the user click log includes data of historically clicked documents within a set time. Wherein, the set time includes any time range before the current time, which can be selected according to the characteristics of different users or the requirements of actual application scenarios. For example, the document click r...

Embodiment 2

[0103] This embodiment provides a document recommendation method, which further includes before step S120 described in Embodiment 1:

[0104] Step S210, acquiring training corpus. Wherein, the training corpus includes a plurality of sample documents and classification data marked on the sample documents.

[0105] Step S220, based on the training corpus, perform supervised learning model training to obtain a pan-label classification model.

[0106] In an implementable manner, step S210, obtaining training corpus, may be performed based on a pan-label classification system, such as Figure 5 As shown, the acquisition of training corpus described in step S210 includes:

[0107]Step S211, establishing a pan-label classification system. Among them, the pan-label classification system can be established by receiving classification rules from outside. The external classification rules can be determined by the editor in combination with the field experience of each vertical catego...

Embodiment 3

[0121] An embodiment of the present invention provides a device for recommending documents, corresponding to the method for recommending documents in Embodiment 1. Such as Figure 8 mentioned, including:

[0122] The original document obtaining module 110 is used to obtain the original document, wherein the original document includes a title and a text, which are respectively used to extract topic information and focus information;

[0123] The pan-tag determining module 120 is configured to determine the pan-tag of the original document by using a pan-tag classification model, wherein the classification granularity of the pan-tag is between the classification granularity based on the topic class information and the classification granularity based on the focus information between the classification granularities of ; and

[0124] The recommended document determining module 130 is configured to determine a recommended document, wherein the recommended document has a matching...

Abstract

The invention provides a document recommending method, device and equipment and a computer readable medium. The document recommending method comprises the steps of obtaining an original document, wherein the original document comprises a title and a text which are used for extracting subject class information and attention focus information respectively; adopting an extensive label classificationmodel, and determining an extensive label of the original document, wherein the classification granularity of the extensive label is between the classification granularity based on the subject class information and the classification granularity based on the attention focus information; determining a recommended document, wherein the recommended document and the original document have matched extensive labels, and modeling of user interests can be better performed based on an extensive label classification model, and more precise document recommending is performed.

Description

technical field [0001] The present invention relates to information recommendation technology, in particular to a pan-tag-based document recommendation method, device, equipment and computer-readable medium. Background technique [0002] With the development of the Internet, information streaming services have gradually replaced traditional media as an important means for people to obtain information. At the same time, the information flow carries too much information, and it is easy for users to be submerged in the ocean of consultation. How to achieve more accurate information push by modeling user interests is an urgent problem to be solved. Contents of the invention [0003] Embodiments of the present invention provide a document recommendation method, device, device, and computer-readable medium, so as to at least solve one or more technical problems in the prior art. [0004] In a first aspect, an embodiment of the present invention provides a document recommendati...
