A Generalized Topic Modeling Approach for Maven Search [chapter]

Ali Daud, Juanzi Li, Lizhu Zhou, Faqir Muhammad
2009 Lecture Notes in Computer Science  
In this paper, we propose a novel semantics and temporal information based maven search (STMS) approach to discover latent topics (semantically related soft clusters of words) between the authors, venues  ...  In the proposed approach, each author in a venue is represented as a probability distribution over topics, and each topic is represented as a probability distribution over words and year of the venue for  ...  In general semantics-based maven finding process, main task is to probabilistically rank discovered mavens for a given query, i.e. p (m/q) where a query is usually comprised of several words or terms.  ...

CheckInside

Moustafa Elhamshary, Moustafa Youssef
2014 Proceedings of the 2014 ACM International Joint Conference on Pervasive and Ubiquitous Computing - UbiComp '14 Adjunct  
This limits the accuracy of current LBSNs in indoor environments, where people spend 89% of their time.  ...  This in turn affects the user experience, in terms of the accuracy of the ranked list of venues, especially for the smallscreens of mobile devices; misses business opportunities; and leads to reduced venues  ...  We thank Moustafa Alzantot for suggesting the CheckInside name. This work is supported in part by a Google Research Award.  ...

Learning to rank for spatiotemporal search

Blake Shaw, Jon Shea, Siddhartha Sinha, Andrew Hogue
2013 Proceedings of the sixth ACM international conference on Web search and data mining - WSDM '13  
In this article we consider the problem of mapping a noisy estimate of a user's current location to a semantically meaningful point of interest, such as a home, restaurant, or store.  ...  Despite the poor accuracy of GPS on current mobile devices and the relatively high density of places in urban areas, it is possible to predict a user's location with considerable precision by explicitly  ...  Retrieval The first step in our spatial search process is to retrieve a set of candidate venues for a given query.  ...
