Abstract

The invention discloses a spatial theme query method based on social media. According to the method, position and semantic information of the text are considered, and topic indices and corresponding query algorithms are designed. To obtain topics of text, the present invention uses a topic model for short text to train social media data. The spatial theme indices combining positions and themes isintroduced. Effective query can be carried out according to the position and the themes. Ranking is carried out on the user according to the correlations between evaluation results and queries, including the theme correlation and the spatial distance, and therefore the query result is more accurate.

Description

technical field [0001] The invention relates to the technical field of spatial theme query, in particular to a social media-based spatial theme query method. Background technique [0002] With the rapid development of social media such as Twitter, the scale of user-generated content (UGC) is getting bigger and bigger. For example, there are about 300 million monthly active users on Twitter, of which 100 million tweet every day. At present, many researchers have proposed various techniques to help users obtain useful information from these large-scale social media data. [0003] In addition, GPS-enabled mobile devices such as cell phones are also widely used, so social media can support location-based services. For example, when a user tweets, he can choose to tag the location of the tweet. So when there is something happening nearby that the user is interested in, the user may discuss it on social media. Also, new users may wish to find some friends nearby with similar h...
