Apparatus and method for social area-of-interest estimation using spatio-textual information

摘要

The present invention provides an apparatus and method for estimating a social interest area using a data base space and text information collected from an SNS server, wherein the text collects all the space tagged records including the POI name A record classifier for expressing each point of interest (POI) together with geonames and then querying all related spatial tagged records including the point of interest (POI) name; Measure from the F-measure computed by the performance calculator, a performance calculation unit that calculates a performance measure including a precision, a recall, and an F-measure on the basis of a point of interest (POI) And a recalculating unit that applies a precision and a recall calculated in the performance calculator based on the optimal radius calculated by the optimizing unit to obtain a repetitive Estimating local social interest to estimate the social interest (AOI) through social AOI estimation algorithm to perform a date (AOI) can consists including parts.
