摘要

Based inverse list indexing method and apparatus that processes spatiotemporal keyword queries, which are searches for space-time information and text-based keywords, in a cloud computing environment that integrates and stores heterogeneous spatial data and space-time data. The indexing method according to an exemplary embodiment of the present invention includes generating a cell-based reverse list for storing the separated spatial data and space-time data by separating spatial data and space-time data; Storing the spatial data and the space-time data in an inverse list based on the cell; And processing the query of the spatiotemporal data and the text-based space-time keyword by concatenating and combining the spatial data and the space-time data using the inverse list.
