Embodiment 1

[0035] The method provided by the present invention mainly has the following steps:

[0036] The first step is to filter unnecessary links and summarize them on a user basis. In this step, some unnecessary links such as open source js library resource access requests and external image resource access requests are filtered out, and the links that users actually want to access are obtained. Then save each user's link and access time in chronological order.

[0037] The second step is to write a web crawler tool to grab the title and content of all linked pages of the user. Since there are many pages visited by users, in order to avoid crawling a certain page repeatedly, it is necessary to establish a hash table to store the links of the pages that have been crawled, so as to avoid repeated crawling.

[0038] In the crawling process, in order to avoid the anti-crawler mechanism of some websites, several strategies need to be used, namely: disguising UserAgent, using agents and avoidi...

Abstract

The invention provides a user portrait forming method based on user access data. Contents in a webpage are obtained and automatically processed by using a crawler tool, an extraction algorithm and a Chinese word segmentation method, the intelligence level and the automation degree are high, and the defects in the prior art are well solved. Moreover, according to the method provided by the invention, user features are learnt by using a machine learning method so as to characterize life, shopping and other behavior preference of a user.

Description

Technical field [0001] The present invention relates to the field of computer technology, and more specifically, to a method for forming a user portrait based on user access data. Background technique [0002] Big data generally refers to a collection of data that cannot be captured, managed, and processed with conventional software tools within a certain time frame. It requires a new processing model to have stronger decision-making power, insight and discovery, and process optimization capabilities to adapt to mass, high Growth rates and diverse information assets. [0003] User portraits are an important technical application generated in the era of big data. Its goal is to establish multi-dimensional descriptive label attributes for users, so that these label attributes can be used to outline the real personal characteristics of users in many aspects. Portraits explore user needs, analyze user preferences, and provide users with more efficient and targeted information delivery...
