Constrained Question Recommendation in MOOCs via Submodularity

Diyi Yang, Jingbo Shang, Carolyn Penstein Rosé
2014 Proceedings of the 23rd ACM International Conference on Conference on Information and Knowledge Management - CIKM '14  
We present experiments conducted on two Massive Open Online Course (MOOC) discussion forum datasets, and demonstrate the effectiveness and efficiency of our submodular method in solving constrained question  ...  In this work, we propose such a constrained question recommendation problem with load balance constraints in discussion forums and use flow based model to generate the optimal solution.  ...  ACKNOWLEDGEMENT This research was funded in part by NSF grants IIS-1320064 and OMA-0836012.  ...

The question that arises is how these recommendations may be produced. The recommendation method using matrix factorization is quite effective, as demonstrated by the Netflix competition.  ...  At the same time, the introduction of many MOOC providers in the market has led individuals to a variety of possible options.  ...  [25] proposed a constrained-based recommender system for providing forum questions to students.  ...

Hinge-Loss Markov Random Fields and Probabilistic Soft Logic [article]

Stephen H. Bach, Matthias Broecheler, Bert Huang, Lise Getoor
2017 arXiv   pre-print
In this paper, we introduce two new formalisms for modeling structured data, and show that they can both capture rich structure and scale to big data.  ...  A fundamental challenge in developing high-impact machine learning technologies is balancing the need to model rich, structured domains with the ability to scale to big data.  ...  This work was supported by NSF grants CCF0937094 and IIS1218488, and IARPA via DoI/NBC contract number D12PC00337.

In this thesis, we propose approaches for solving some common standardized teststaken by students such as reading comprehensions, elementary science exams, geometry questions in the SAT exam and mechanics  ...  questions in the AP physics exam.Answering these test problems requires deep linguistic (and sometimes visual) understanding and reasoning capabilities which is challenging for modern AI systems.  ...  Diagram and Question Parsing P2P parses geometry problems via a multi-stage approach.  ...

The goal is to answer queries in terms of the target ontology in a federated manner. From a practical point of view, this begs the question: where does the target ontology and the mappings come from?  ...  This raises the question how the WoD can (i) maintain its success when government subsidies disappear and (ii) convince commercial entities to share their wealth of data.  ...  We investigate this question via two models for studying robust estimation, learning, and optimization.  ...

We have investigated the interplay of temporal and multi-way interactions in [3] and found effects, that differ from their projections.  ...  In my talk, I outline two ways of extending higher-order model research, motivated by my previous work on the interplay of dynamics and multi-body topology [1, 2].  ...  Recommendations To bridge the gaps in the I/O community construction, we propose the following recommendations.  ...
