【摘要】 针对传统关系数据库处理海量空间文本数据的不足,基于HBase数据库提出了一种结合Geohash编码与分词技术的空间文本索引方案,并基于该空间文本索引提出了一种多边形区域内的空间关键字查询算法。通过与传统经纬度索引方案的实验比较,验证了算法的高效性和可扩展性。更多还原

【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.更多还原
