Detecting dominant locations from search queries

Lee Wang, Chuang Wang, Xing Xie, Josh Forman, Yansheng Lu, Wei-Ying Ma, Ying Li
2005 Proceedings of the 28th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '05  
QDL is a subjective and collective attribute of search queries and we are able to detect QDLs from both queries containing geographical location names and queries not containing them.  ...  In this paper, we define a search query's dominant location (QDL) and propose a solution to correctly detect it.  ...  CONCLUSIONS AND FUTURE WORK In this paper, we presented a novel solution for detecting dominant locations from search queries.  ...

Spatial-Aware Local Community Detection Guided by Dominance Relation [article]

Li Ni, Hefei Xu, Yiwen Zhang, Wenjian Luo
2022 arXiv   pre-print
Specifically, to address the SLCD problem, we design a novel spatial aware local community detection algorithm based on dominance relation, but this algorithm incurs high cost.  ...  However, existing studies suffer from two limitations: a) the criteria of defining communities are determined by parameters, which are difficult to set; b) algorithms may require global information and  ...  Local community detection is similar to community search; both detect the community that contains the given/query node. The two are not identical, however.  ...

In-Network Processing of Nearest Neighbor Queries for Wireless Sensor Networks [chapter]

Yuxia Yao, Xueyan Tang, Ee-Peng Lim
2006 Lecture Notes in Computer Science  
To enable object tracking applications, spatial queries such as nearest neighbor queries are to be supported in these networks. The queries can be injected by the user at any sensor node.  ...  Due to the limited power supply for sensor nodes, energy efficiency is the major concern in query processing. Centralized data storage and query processing schemes do not favor energy efficiency.  ...  This is different from our objective to locate the nearest objects to the query point because the nearest object may not be detected by the nearest sensor node.  ...

Compact Features for Birdcall Retrieval from Environmental Acoustic Recordings

Xueyan Dong, Michael Towsey, Jinglan Zhang, Paul Roe
2015 2015 IEEE International Conference on Data Mining Workshop (ICDMW)  
In the algorithm, an event-based searching scheme and compact features are developed. In detail, ridge events are detected from audio files using event detection on spectral ridges.  ...  Then event alignment is used to search through audio files to locate candidate instances. A similarity measure is then applied to dimension-reduced spectral ridge feature vectors.  ...  Searching for candidates Given a query birdcall, the procedure here searches through a one-minute spectrogram to locate matching candidates.  ...
