Geographical topic discovery and comparison

Zhijun Yin, Liangliang Cao, Jiawei Han, Chengxiang Zhai, Thomas Huang
2011 Proceedings of the 20th international conference on World wide web - WWW '11  
This paper studies the problem of discovering and comparing geographical topics from GPS-associated documents.  ...  To answer these questions, this paper proposes and compares three ways of modeling geographical topics: location-driven model, text-driven model, and a novel joint model called LGTA (Latent Geographical  ...  National Science Foundation under grants CCF-0905014, CNS-0931975, CNS-1027965, and IIS-0713581, by the Army Research Laboratory under Cooperative Agreement Number W911NF-09-2-0053 (NS-CTA), and Air Force  ...

2012 Proceedings of the 21st ACM international conference on Information and knowledge management - CIKM '12  
A novel framework G-WSTD that contains search session derivation, geographic information extraction and geographic search topic discovery is developed to support a variety of downstream web applications  ...  The second one is the Regional Search Topic Model (RSTM), which focuses on a specific region on the map and discovers web search topics that demonstrate geographic locality.  ...  In this paper, we propose a new framework named Geographic Web Search Topic Discovery (G-WSTD), which addresses the aforementioned challenges and conducts geographic web search topic discovery from two  ...

A Location-Sentiment-Aware Recommender System for Both Home-Town and Out-of-Town Users [article]

Hao Wang, Yanmei Fu, Qinyong Wang, Hongzhi Yin, Changying Du, Hui Xiong
2017 arXiv   pre-print
Finally, we deploy LSARS into two practical application scenes: spatial item recommendation and target user discovery.  ...  Some current researches are focusing on modelling individual and collective geographical preferences for spatial item recommendation based on users' check-in records, but they fail to explore the phenomenon  ...  As regions and topics are interdependent, LSARS combines geographical clustering and topic modelling (i.e., Latent Dirichlet allocation (LDA) [2] ) into a uni ed process.  ...

Enabling the Discovery of Thematically Related Research Objects with Systematic Spatializations

Sara Lafia, Christina Last, Werner Kuhn, Michael Wagner
2019 Conference On Spatial Information Theory  
We discuss and implement two distinct spaces for exploration: a field view of research topics and a network view of research objects.  ...  Its application to the design of library discovery tools offers two distinct and intuitive ways to gain insights into the thematic relatedness of research objects, regardless of the disciplinary terms  ...  Acknowledgements We gratefully acknowledge the contributions that André Bruggmann and Sara Fabrikant of University of Zurich's Geographic Information Visualization and Analysis Unit made during André's  ...

Towards Detecting Social Events by Mining Geographical Patterns with VGI Data

Zhewei Liu, Xiaolin Zhou, Wenzhong Shi, Anshu Zhang
2018 ISPRS International Journal of Geo-Information  
This workflow first uses data geographical topic modeling to detect the hashtag communities with VGI semantic data.  ...  This study examined the feasibility of detecting events by investigating the geographical patterns of social media data and can be applied to urban knowledge retrieval.  ...  Acknowledgments: We would like to thank the anonymous reviewers for their insightful comments and substantial help on improving this article.  ...
