It has been insufficiently explored how to perform density-based clustering by exploiting textual attributes on social media. In this paper, we aim at discovering a social point-of…
Clustering-Based Collaborative Filtering Using an Incentivized/Penalized User Model
Cong Tran, Jang-Young Kim, Won-Yong Shin +1
Giving or recommending appropriate content based on the quality of experience is the most important and challenging issue in recommender systems. As collaborative filtering (CF) is…
A Personalized Preference Learning Framework for Caching in Mobile Networks
Adeel Malik, Joongheon Kim, Kwang Soon Kim +1
This paper comprehensively studies a content-centric mobile network based on a preference learning framework, where each mobile user is equipped with a finite-size cache. We consid…
Multi-Stream Opportunistic Network Decoupling: Relay Selection and Interference Management
Huifa Lin, Won-Yong Shin, Bang Chul Jung
We study multi-stream transmission in the channel with interfering relay nodes, consisting of multi-antenna source--destination (S--D) pairs and singl…
Network-Decomposed Hierarchical Cooperation in Ad Hoc Networks With Social Relationships
Cheol Jeong, Won-Yong Shin
In this paper, we introduce a network-decomposed hierarchical cooperation (HC) protocol and completely characterize the corresponding throughput--delay trade-off for a large wirele…
Improved Density-Based Spatio--Textual Clustering on Social Media
Minh D. Nguyen, Won-Yong Shin
DBSCAN may not be sufficient when the input data type is heterogeneous in terms of textual description. When we aim to discover clusters of geo-tagged records relevant to a particu…
DIR-ST: Delineation of Imprecise Regions Using Spatio--Temporal--Textual Information
Cong Tran, Won-Yong Shin, Sang-Il Choi
An imprecise region is referred to as a geographical area without a clearly-defined boundary in the literature. Previous clustering-based approaches exploit spatial information to…
On the Effects of Subpacketization in Content-Centric Mobile Networks
