Abstract:

According to the shortcomings of traditional relational databases in handling massive spatial text data, we present a spatial keyword index scheme based on HBase, which  integrates Geohash codes and word segmentation. In addition, on the basis of the spatial keyword index, we also propose a spatial keyword query algorithm within polygon regions. Compared with traditional index schemes based on longitude and latitude coordinates, the proposed algorithm achieves better efficiency and scalability .
