Problems solved by technology

In recent years, with the emergence of the ESA (Explicit semantic analysis) algorithm, words can be mapped to a high-dimensional semantic concept space through this method, so the impact of the diversification of the form of the word itself will be less when performing semantic comparisons , although ESA has been successfully applied in semantic comparison, there are still not many studies on text semantic segmentation combined with ESA algorithm

Embodiment Construction

[0069] Take an encyclopedia article describing the entry of "Hong Kong" as an example to further describe the present invention. Each module of the system is used in turn for processing, as follows:

[0070] (one) text input module, Used to enter text describing the term.

[0071] (two) Region of interest calibration module, The user manually specifies the semantic content of interest to the user by setting the beginning sentence and the end sentence. The specific settings are as follows: figure 2 shown (in the dotted box).

[0072] (three) Semantic feature calculation module, Semantic feature calculation based on the ESA method:

[0073] (1) The calculation basis comes from the Wikipedia knowledge base;

[0074] (2) Firstly, word segmentation is performed on all the articles in the knowledge base, and the corresponding matrix between words and concepts is calculated, and the element values ​​in the matrix are the TF-IDF calculated by the corresponding words in the da...

Abstract

The invention belongs to the technical field of electronic reading, and particularly relates to an automatic navigating method and system for interested semantic range of electronic reading. The system mainly comprises a primary navigation module and a precise navigation module which are in cascade connection. The method includes firstly performing target tracking on a few selected content of readers by means of CamShift in video tracking, determining boundary of the semantic range according to a target boundary in instant of loss of inspected target, and obtaining a primary navigation result; then precisely navigating according to semantic skip between inspected adjacent sentences, and submitting the final result to the readers. The automatic navigating method and system are capable of providing the readers with really interested content, and limited reading time and effort of the readers are consequently saved.

Description

technical field [0001] The invention belongs to the technical field of electronic reading, and in particular relates to a method and system for automatic navigation of an interested semantic range of electronic reading. Background technique [0002] With the development of computer technology and information technology, in addition to the traditional paper reading method, electronic reading has become an important way for people to obtain scientific and cultural knowledge, such information includes Internet news, entry introduction articles on encyclopedia websites, Mobile newsletters on smartphones, etc., for users to read. However, due to the characteristics of compact form, diverse content, and large amount of information, these information can sometimes cover multiple topics or fields within the length of an article. At the same time, the update speed of this information is also slow Very quickly, based on the above characteristics, readers are required to quickly locat...
