Embodiment Construction

[0057] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0058] Internet public opinion events are composed of a series of event fragment information. These event fragment information have time tags, marking the development process of the entire event. Displaying the event puzzle according to the development context can give users a very clear understanding of the process. In addition, these event fragment information also has geographical location information, which represents the development process of the entire event according to the geographical region. Displaying the event according to the space in the collage can also provide users with the context of the...

Abstract

Provided is a time-space dimension based event graph splicing method used for an internet public-sentiment system. The method utilizes a HBase column storage oriented non-relational database to storelarge amounts of internet public-sentiment event fragment information in a (space, time and key word) mode, quick event graph splicing according to time-space attributes is completed by proposing a time-space index structure and designing a corresponding query method. Compared with the other inventions, all fragment information is comprehensively organized according to time and space so as to completely show a whole event, accordingly a user can comprehensively and systematically know the time-space cause and effect development of the event, technical support is provided for development prediction and disposal decision making of internet public-sentiment events, and powerful assistance is provided for achieving social management functions.

Description

technical field [0001] The invention relates to the technical field of information retrieval in the field of databases within the scope of computer science, in particular to an event mosaic method for the retrieval requirement of mosaic events according to time-space attributes in an Internet public opinion system. Background technique [0002] With the continuous promotion and improvement of Internet technology and applications, more and more organizations and individuals choose to release information, expound opinions, and express their wishes through the Internet. The important needs of various commercial organizations in the field of Internet information management. The Internet public opinion system collects, stores, retrieves, and analyzes all kinds of Internet information of concern, and then sorts out and analyzes the focus of public opinion of concern, grasps netizens' views and opinions on events, and provides information for situation judgment and public opinion g...
