Problems solved by technology

[0003] The introduction of digital map technology as the underlying support of network news will enable readers to have a more intuitive experience of geographical location information in news events. Using maps as guides and geographical locations as clues to classify and explain news events can greatly make up for the traditional The news is deficient in terms of unclear spatial description and orientation abstraction. However, when the existing technology analyzes the location of the news event, the accuracy and fine-grainedness of the existing location extraction algorithm are low.

Embodiment Construction

[0021] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] A geographical location analysis method based on multilingual news is characterized in that it comprises the following steps:

[0023] (1) Establish a geographic location database;

[0024] (1.1) Create a data package based on a single country / region;

[0025] (1.2) Set the data level according to the administrative division in the data package of each country / region;

[0026] (1.3) Store the corresponding geographic location name under each data level.

[0027] (1.4) Add a corresponding mark for each geographic location name, and the function of adding a mark is to facilitate the search in the database in the subsequent steps.

[0028] (2) Use the ICTCLAS word segmentation method to perform word segmentation processing on multilingual news, obtain multiple geographical location-related keywords, and store them in the word...

Abstract

The invention provides a geographical position analysis method based on multi-language news. The method comprises the steps that a geographical position database is established; word segmentation processing is conducted on multi-language news, and the multi-language news is stored in a word segmentation container; comparison between key words in the word segmentation container and key words in thegeographical position database is conducted to obtain matching key words; analysis is conducted on the matching key words according to a geological position analysis algorithm; the analyzed matchingkey words are adopted as the geological position where the news takes place. According to the method, the place where the news takes place can be automatically and accurately acquired, an extraction method of the place where the news takes place based on a factor association tree is achieved, and under the condition that manual intervention is not involved, the specific place where the news takesplace is automatically and accurately identified; a method in which a database of relationships between layered place names matches with an algorithm mode is established, and the problem of disorderedplace name levels is solved.

Description

technical field [0001] The present invention relates to positioning technology. Background technique [0002] In recent years, with the rapid development of Internet technology, various upper-layer application services based on geographic location information technology emerge in an endless stream, all of which provide people with a unique user experience based on geographic location information. Multilingual news geographic location analysis integrates digital map technology and Internet news, the most popular and popular communication carrier on the Internet, and focuses on the important role of multilingual network news geographic location information in news events. [0003] The introduction of digital map technology as the underlying support of network news will enable readers to have a more intuitive experience of geographical location information in news events. Using maps as guides and geographical locations as clues to classify and explain news events can greatly ma...
