Embodiment Construction

[0014] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0015] like figure 1 As shown, a knowledge-aware-based news recommendation method includes the following steps:

[0016] Step 1: Divide the dataset into training and test sets.

[0017] Among them, the training set is used to optimize the parameters, and the test set is used to test the effect.

[0018] For example, by implementing validation experiments on the BingNews dataset. Each record in the dataset contains information such as user ID, news headline, whether the user clicked, and a timestamp.

[0019] Step 2: Extract entity knowledge information in news text.

[0020] Specifically include the following steps:

[0021] Step 2.1: Use the entity linking technology to link and disambiguate the words in the news text with the entities in the knowledge graph to obtain a news entity set.

[0022] Step 2.2: Based on the news entity set, construct a...

Abstract

The invention discloses a news recommendation method based on knowledge perception, which belongs to the technical field of artificial intelligence and network information big data. Firstly, entities are identified from news texts, matched with entities in the knowledge graph, and vector representations of entities and relationships are obtained using the knowledge representation learning model. Then, a convolutional neural network is used to fuse word vectors and entity vectors of news, and learn comprehensive features of news from them. For each news candidate, based on the correlation between the user's browsing history and the news candidate, user features are dynamically constructed using an attention network. At the same time, considering the path between the entity in the clicked news and the entity in the candidate news, the long short-term memory network is used to generate path features from the path. Finally, with the candidate news features, user features and path features as input, the multi-layer perception mechanism is used to calculate the probability of the user clicking on the candidate news to achieve the purpose of recommendation. The invention can effectively excavate the knowledge association between news, which is significantly better than the traditional method.

Description

technical field [0001] The invention relates to a news recommendation method based on knowledge perception, belonging to the technical field of artificial intelligence and network information big data. Background technique [0002] With the popularity of the mobile Internet, more and more people choose to obtain news and information through the mobile Internet. For news content platforms, it is very important to build a personalized news recommendation system that can capture users' reading interests and push relevant information to them. [0003] Generally speaking, in the context of news recommendation, the following points need to be paid attention to: First, news has a strong timeliness and changes quickly, so traditional collaborative filtering methods are not applicable. Second, users are usually interested in news content of some specific topics. How to build an interest preference model for users according to the user's browsing history, and determine whether the ca...
