You Li Lu · 2019
With the wide-spread usage of social media such as Facebook and Twitter, large amount of data with both spatial and temporal information has become available.Topic modelling has been a useful tool to uncover latent information from such data.This thesis considers a specific type of topic model computational problem called topic-range queries, to LDA Topic Models In View of Data Indexing Structures: Query 1-4 .K.2 Comparison of Bhattacharyya Distance from FSS and OLDA Topic Models to LDA Topic Models In View of Data Indexing Structures: Query 5-8 .K.3 Comparison of Bhattacharyya Distance from FSS and OLDA Topic Models to LDA Topic Models In View of Data Indexing Structures: Query 9-12 .K.4 Comparison of Bhattacharyya Distance from FSS and OLDA Topic Models to LDA Topic Models In View of Data Indexing Structures: Query 13-15 x Supported 3D (2D for Quadtree), can be extended to multidimensional data structure as a variant Supported Supported Supported Exact range query supported or not Supported
