Problems solved by technology

[0004] Existing research often finds users' reading interest through users' browsing, clicking and downloading, etc., and some only use the indicators of users' gaze and gaze time during reading to calculate users' reading interest, which cannot dig out users' interests and needs well. A general approach to efficiently and accurately identify user reading interest regions

Embodiment Construction

[0050] The technical solutions of the present invention will be described in further detail below in conjunction with specific embodiments.

[0051] Taking patent documents as an example, experiments were conducted on 30 teachers and graduate students engaged in scientific research in the three disciplines of agricultural engineering, computer science and fluid machinery in Jiangsu University to automatically identify areas of interest for scientific research users to read patent documents.

[0052] Data were collected using a Tobii T60XL widescreen eye tracker.

[0053] The computer automatically divides the patent documents into the following 12 reading areas according to the metadata items of the patent documents, as shown in Table 1.

[0054] Table 1 Comparison Table of Reading Areas and Contents of Metadata Items of Patent Documents

[0055]

[0056] Reading range x or y takes values ​​from 1 to 12.

[0057] Step 1: Collect the eye movement data of users in the proce...

Abstract

The invention discloses a method for automatically identifying a user's reading interest area. The eye tracker captures the user's access time, fixation times, pupil diameter and other indicators in real time when reading, and combines the use of the relationship matrix of the number of return times to automatically mine the user's reading interest area. Reading concerns and interests. The invention improves the accuracy and pertinence of identifying the reading interest of the user, and can be applied to identifying the reading interest of the user, so as to more accurately push the reading content that the user is interested in.

Description

technical field [0001] The invention belongs to the fields of user psychology and informatics, and in particular relates to a user interest discovery technology based on user reading psychology and reading behavior analysis. Background technique [0002] The user's focus or interest in the content is reflected in a certain aspect of their needs. The information demand radar model proposed by Cho-Wei Shih et al. quantifies the degree of content demand. In order to help users distinguish points of interest and facilitate reading, the State Intellectual Property Office has used the functions of highlighting, high density, and focusing on the patent document viewing page; for the expression of user interests, Miao Hanqin has developed a patent information retrieval system that integrates ontology and user interests , and design ontology representations of patent retrieval field ontology, international patent classification table and user interest model. [0003] Eye-tracking t...
