Introduction to the Special Issue on Linking Social Granularity and Functions
Qi He, Juanzi Li, Rong Yan, John Yen, Haizheng Zhang
Article No.: 22
DOI: 10.1145/2594452

Infer User Interests via Link Structure Regularization
Jinpeng Wang, Wayne Xin Zhao, Yulan He, Xiaoming Li
Article No.: 23
DOI: 10.1145/2499380

Learning user interests from online social networks helps to better understand user behaviors and provides useful guidance to design user-centric applications. Apart from analyzing users' online content, it is also important to consider users'...

Cluster-Based Collaborative Filtering for Sign Prediction in Social Networks with Positive and Negative Links
Amin Javari, Mahdi Jalili
Article No.: 24
DOI: 10.1145/2501977

Social network analysis and mining get ever-increasingly important in recent years, which is mainly due to the availability of large datasets and advances in computing systems. A class of social networks is those with positive and negative links....

CIM: Community-Based Influence Maximization in Social Networks
Yi-Cheng Chen, Wen-Yuan Zhu, Wen-Chih Peng, Wang-Chien Lee, Suh-Yin Lee
Article No.: 25
DOI: 10.1145/2532549

Given a social graph, the problem of influence maximization is to determine a set of nodes that maximizes the spread of influences. While some recent research has studied the problem of influence maximization, these works are generally too time...

Structure and Overlaps of Ground-Truth Communities in Networks
Jaewon Yang, Jure Leskovec
Article No.: 26
DOI: 10.1145/2594454

One of the main organizing principles in real-world networks is that of network communities, where sets of nodes organize into densely linked clusters. Even though detection of such communities is of great interest, understanding the...

Joint Link Prediction and Attribute Inference Using a Social-Attribute Network
Neil Zhenqiang Gong, Ameet Talwalkar, Lester Mackey, Ling Huang, Eui Chul Richard Shin, Emil Stefanov, Elaine (Runting) Shi, Dawn Song
Article No.: 27
DOI: 10.1145/2594455

The effects of social influence and homophily suggest that both network structure and node-attribute information should inform the tasks of link prediction and node-attribute inference. Recently, Yin et al. [2010a, 2010b] proposed an...

Description-Driven Community Detection
Simon Pool, Francesco Bonchi, Matthijs van Leeuwen
Article No.: 28
DOI: 10.1145/2517088

Traditional approaches to community detection, as studied by physicists, sociologists, and more recently computer scientists, aim at simply partitioning the social network graph. However, with the advent of online social networking sites, richer...

Learning Probabilistic Hierarchical Task Networks as Probabilistic Context-Free Grammars to Capture User Preferences
Nan Li, William Cushing, Subbarao Kambhampati, Sungwook Yoon
Article No.: 29
DOI: 10.1145/2589481

We introduce an algorithm to automatically learn probabilistic hierarchical task networks (pHTNs) that capture a user's preferences on plans by observing only the user's behavior. HTNs are a common choice of representation for a variety of...

A Framework for Effectively Choosing between Alternative Candidate Partners
Shulamit Reches, Meir Kalech, Philip Hendrix
Article No.: 30
DOI: 10.1145/2589482

Many multi-agent settings require that agents identify appropriate partners or teammates with whom to work on tasks. When selecting potential partners, agents may benefit from obtaining information about the alternatives, for instance, through...

Conveying Semantics through Visual Metaphor
Derrall Heath, David Norton, Dan Ventura
Article No.: 31
DOI: 10.1145/2589483

In the field of visual art, metaphor is a way to communicate meaning to the viewer. We present a computational system for communicating visual metaphor that can identify adjectives for describing an image based on a low-level visual feature...

Mining Check-In History for Personalized Location Naming
Defu Lian, Xing Xie
Article No.: 32
DOI: 10.1145/2490890

Many innovative location-based services have been established to offer users greater convenience in their everyday lives. These services usually cannot map user's physical locations into semantic names automatically. The semantic names of...

Exploiting User Preference for Online Learning in Web Content Optimization Systems
Jiang Bian, Bo Long, Lihong Li, Taesup Moon, Anlei Dong, Yi Chang
Article No.: 33
DOI: 10.1145/2493259

Web portal services have become an important medium to deliver digital content (e.g. news, advertisements, etc.) to Web users in a timely fashion. To attract more users to various content modules on the Web portal, it is necessary to design a...

AutoLCA: A Framework for Sustainable Redesign and Assessment of Products
M. Shahriar Hossain, Manish Marwah, Amip Shah, Naren Ramakrishnan, Layne T. Watson
Article No.: 34
DOI: 10.1145/2505270

With increasing public consciousness regarding sustainability, companies are ever more eager to introduce eco-friendly products and services. Assessing environmental footprints and designing sustainable products are challenging tasks since they...

Multi-Label Classification Based on Multi-Objective Optimization
