Problems solved by technology

[0004] It is necessary to analyze the webpage, extract the text of the webpage, analyze the webpage, and extract the text of the webpage. The algorithm is complex and the calculation is large
And because the webpages on the Internet are extremely irregular, the effect of extracting the text of the webpage is only good for a specific type of webpage, such as the productized Chinese Academy of Sciences, Massive, etc. webpage theme extraction components, but they are all only for specific types webpage, and webpage text extraction is closely related to keyword extraction. If the extracted webpage text contains other information such as advertisements and copyrights, the advertisements, copyrights and other information may not be extracted as the text; or some important content has not been extracted. Extracted, the accuracy of keyword extraction will be greatly reduced
Therefore, the existing web page analysis method has a large amount of calculation, and the accuracy of keyword extraction is not high.

Abstract

The embodiment of the invention discloses a webpage keywords extracting method, comprising the following steps: crawling an internet webpage; extracting an anchor text of the crawled webpage and extracting a URL (uniform resource locator) of the anchor text and the surrounding text of the anchor text; extracting keywords from the anchor text and the surrounding text of the anchor text according to the pre-formulated rules; and correlating the keywords with the URL of the anchor text, so as to use the keywords as the webpage keywords of the webpage directed by the URL of the anchor text. The embodiment of the invention also discloses a webpage keywords extracting device and a system. By adopting the technical scheme, the calculation amount for extraction of the webpage keywords can be reduced, and the accuracy for the keywords extraction is improved.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method, device and system for extracting web page keywords. Background technique [0002] The extraction of web page keywords is a hot issue in Internet applications under the background of massive data. Extract appropriate keywords for web pages, which can be used to prompt and summarize the content of web pages. Webpage keyword extraction is widely used in keyword-based precise advertising, webpage summarization, webpage retrieval, and user behavior analysis. [0003] Traditional approaches (eg, KEA keyword extraction method) tend to extract keywords from web page text. First crawl the webpage, then analyze the webpage, extract the title, metadata (webpage metadata) information and text of the webpage. Then segment the words, remove the stop-word (stop words) to get the candidate keywords, then extract the characteristics of the candidate keywords, and score the candidate keywo...
