However, as the number of agricultural web pages continues to increase, the similarity and repetition of web page content have become more and more serious, bringing inconvenience to users. Therefore, this paper intends to study the technology of Chinese agricultural web page de-duplication and similarity judgment to improve the quality and readability of agricultural web pages.This paper first reviews and summarizes relevant research at home and abroad, analyzes the research status and existing problems of web page de-duplication and similarity judgment technology. Then, this paper proposes a new method, the web page similarity calculation method based on feature extraction and vector space model. This method analyzes the web page features, extracts keywords and related attribute information, constructs the feature vector of the web page, and calculates the similarity of the web page using cosine similarity.精品文档---下载后可任意编辑Finally, this paper proposes preliminary ideas and plans for research methods and experimental designs, including web page acquisition and preprocessing, feature extraction and vector space model construction, similarity calculation, and experimental verification. Through the implementation of this research, it can provide technical support and useful reference for agricultural informatization construction and web content management.Keywords: Agricultural web page; de-duplication; similarity judgment; feature extraction; vector space model.
