Example Embodiment

[0029] Such as figure 1 , The automatic summarization method of English text based on eye tracking includes the following modules: eye tracking device 10, user attention time sample collection 20, user interest degree prediction 30, traditional text automatic summarization method 40, user interest degree adjustment 50, text automatic summary result 60 ,Specific steps are as follows:

[0030] Step 1) Get the user's attention time for all words in the text when reading the electronic document, the specific method is:

[0031] (a) Initialize the user attention time of all words in the text to 0.

[0032] (b) At intervals of 0.1 seconds, the focus position (x, y) of the user's eyeball on the screen is obtained by the eye-tracking device. The eye tracking device is assembled with a common camera (Logitech QuickCam NotebookPro) and an open source eye tracking system opengazer.

[0033] (c) The position of each word wi in the text on the current screen is (xi, yi), then the increase AT(w...

Abstract

The invention relates to an English text automatic abstracting method based on eye tracking. Existing methods can not generate a personalized text abstract aiming at different readers. The method comprises the following steps of: obtaining the concerning time of a user to all words in a text when reading an electronic text by utilizing an eyeball tracking device or a camera; predicating the user interest in all sentences based on test similarity; and generating a personalized automatic abstracting result by utilizing the combination of user interest and text automatic abstracting algorithm. The method can effectively combine the user interest in an English text automatic abstracting process so as to lead the final test automatic abstracting result to be more similar to the abstract content expected by the user, thereby causing automatic abstracting software to provide better personalized service to the user.

Description

technical field [0001] The invention belongs to the field of computer information retrieval and man-machine interface, and relates to a method for automatic summarization of personalized English text based on eyeball tracking. Background technique [0002] At present, a lot of research work and achievements have been made on the automatic summarization of computer English text, including automatic summarization of general documents and documents in a specific knowledge field. For example: "Summarization in the Small" proposed by Richard Alterman et al. in "Advances in Cognitive Science" in 1986 , "Text Summarization" proposed in "Encyclopedia of Artificial Intelligence" ("Encyclopedia of Artificial Intelligence") in 1992; Klaus Zechner (Klaus Zechner) at the SIGIR2001 conference in 2001 "Automatic Generation of Concise Summaries of SpokenDialogues in Unrestricted Domains" proposed by L.Zuang et al. at the CIKM2006 conference in 2006 Movie Review Mining and Automatic Summar...
