Temporal Spatial-Keyword Top-k publish/subscribe

Lisi Chen, Gao Cong, Xin Cao, Kian-Lee Tan
2015 2015 IEEE 31st International Conference on Data Engineering  
Given a TaSK query, we continuously maintain up-to-date top-k most relevant results over a stream of geo-textual objects (e.g., geo-tagged Tweets) for the query.  ...  Massive amount of data that are geo-tagged and associated with text information are being generated at an unprecedented scale. These geo-textual data cover a wide range of topics.  ...  These geo-textual objects can be modeled as continuously arriving streams, and many real-world applications can benefit from a publish/subscribe system for streams of such geo textual objects.  ...

EFTG: Efficient and Flexible Top-K Geo-textual Publish/Subscribe

2018 KSII Transactions on Internet and Information Systems  
However, most of the existing Top-k geo-textual publish/subscribe schemes have the following deficiencies: (1) All publications have to be scored for each subscription, which is not efficient enough. (  ...  Different from the traditional publish/subscribe format, geo-textual data is published and subscribed in the form of dynamic data flow in the mobile network.  ...  Unlike traditional publish/subscribe systems, geo-textual data includes a geographic description and a textual description that are continuously generated and propagated in the form of a dynamic data stream  ...

Distributed Publish/Subscribe Query Processing on the Spatio-Textual Data Stream [article]

Zhida Chen, Gao Cong, Zhenjie Zhang, Tom Z.J. Fu, Lisi Chen
2017 arXiv   pre-print
However, the explosive growth of data scale and user base has posed challenges to the existing centralized publish/subscribe systems for spatio-textual data streams.  ...  In this paper, we propose our distributed publish/subscribe system, called PS2Stream, which digests a massive spatio-textual data stream and directs the stream to target users with registered interests  ...  We also acknowledge the "AWS Cloud Credits for Research" program for its support of this work.  ...

Efficient processing of continuous spatial-textual queries over geo-textual data stream

Kalpana Vivek Metre, Madan Kharat
2022 Indonesian Journal of Electrical Engineering and Computer Science  
The various continuous geo-keyword query processing methods normally lack the support for fuzzy keyword matching when processing the objects from the geo-textual data stream.  ...  For the spatialkeyword data stream, the performance plays a vital role as the geo information and keyword description matching is needed for every incoming streaming object.  ...  However, it is proposed a time-based publish/subscribe system while taking into account both textual and spatial factors and semantic-based top-k search is performed [31] .  ...
