A spatial text query scheme based on semantic-aware
Hongbo Li, Hong Bo Zhu, Zongmin Cui · 2019
In some application scenarios, the strategy based on text similarity cannot accurately find the spatial text data that users need. Therefore, we propose a spatial text query scheme based on semantic-aware. We name this scheme as SSA. We study spatial text queries based on semantic-aware. We improve LDA algorithm to filter out some worthless candidate data. The experimental results show that our scheme has good basic attributes and query accuracy.
