DM2 Lab: Data Mining towards Decision Making

"Build trustworthy intelligent systems to support decision-making process with rich knowledge in massive behavior data." -- dm_square

Data-driven User Behavior Modeling: Understand behavior intention, model social and spatio-temporal context, represent unstructured behavior content, and consolidate into real use such as recommender systems, anti-fraud systems, and event monitoring systems.

Text mining: Concept hierarchy construction
Q: Given all data science papers, can we automatically construct multifaceted concept hierarchy and design syllabus for the Data Science class? The methodology would be extended to any research field besides Data Science.
Xueying Wang: PhD student (2016)
Email: xwang41@nd.edu
Text mining: Conditional/temporal fact extraction
Q: Given text documents (news, papers), can we extract (entity, attribute, value)-tuples, called EAV-tuples, and their conditions (e.g., from when to when, under what temperature)?
Daheng Wang: PhD student (2016)

Representation learning: Mining dynamic heterogeneous social media data
Q: Given heterogeneous signals/structures such as social networks, topics/events, spatio-temporal dimensions, and sentiments, can we learn low-dimensional representations for efficient social media mining?
Qi Li: PhD student (2017)
Email: qli8@nd.edu
Representation learning: Bio-network construction and knowledge discovery
Q: Given heterogeneous data signals (e.g., gene expression, function hierarchy, profile, time series), can we learn to preserve the structures, construct correlation networks, and discover interesting patterns from the networks?
