Predicting Facial Indicators of Confusion with Hidden Markov Models
In Affective Computing and Intelligent Interaction (pp. 97–106).
TL;DR:
A predictive model of learner confusion during task-oriented human-human tutorial dialogue that leverages textual dialogue, task, and facial expression history to predict upcoming confusion within a hidden Markov modeling framework is created.

2011 chapter
Generalizing Models of Student Affect in Game-Based Learning Environments
In Affective Computing and Intelligent Interaction (pp. 588–597).
TL;DR:
The findings suggest that predictive models of affect that are learned from empirical data may have significant dependencies on the populations on which they are trained, even when the populations themselves are very similar.

2011 chapter
When Off-Task is On-Task: The Affective Role of Off-Task Behavior in Narrative-Centered Learning Environments
In Lecture Notes in Computer Science (pp. 534–536).
TL;DR:
Results from an empirical study of students interacting with the CRYSTAL ISLAND environment indicate that off-task behavior generally has negative impacts on learning, but analyses of students' affective transitions suggest that some students may be using off- task behavior as a strategy to regulate negative emotions.

Early Prediction of Cognitive Tool Use in Narrative-Centered Learning Environments
In Lecture Notes in Computer Science (pp. 320–327).
TL;DR:
An investigation into machine-learned models for making early predictions about students' use of a specific cognitive tool in the Crystal Island learning environment suggests that support vector machine and naive Bayes models offer considerable promise for generating useful predictive models of cognitive tool use in narrative-centered learning environments.

Defending against Sybil Nodes in BitTorrent
In NETWORKING 2011 (pp. 25–39).
TL;DR:
This paper presents defenses against threats from Sybil attackers in BitTorrent using a simple, direct reputation scheme called GOLF, which effectively detects and blocks potential attackers, despite false accusation.

On an identity of Gessel and Stanton and the new little Göllnitz identities
Advances in Applied Mathematics, 46(1-4), 563–575.
author keywords: Integer partitions; q-Series identities; q-Gauss summation; Little Gollnitz partition theorems; Gollnitz-Gordon partition theorem; Lebesgue identity
TL;DR:
It is shown that an identity of Gessel and Stanton can be viewed as a symmetric version of a recent analytic variation of the little Gollnitz identities, and a refinement of the Gessel-Stanton identity is derived that suggests a similar interpretation is possible.

A control system testbed to validate critical infrastructure protection concepts
International Journal of Critical Infrastructure Protection, 4(2), 88–103.
author keywords: Testbed; Industrial control system; SCADA; Smart grid; Cybersecurity
TL;DR:
The testbed enables a research process in which cybersecurity vulnerabilities are discovered, exploits are used to understand the implications of the vulnerability on controlled physical processes, identified problems are classified by criticality and similarities in type and effect, and finally cybersecurity mitigations are developed and validated against within the testbed.

In The Semanic Web: Research and Applications (pp. 123–138).
TL;DR:
This paper presents an approach for optimizing skyline queries over RDF data stored using a vertically partitioned schema model based on the concept of a "Header Point" which maintains a concise summary of the already visited regions of the data space.

Effectively Interpreting Keyword Queries on RDF Databases with a Rear View
In The Semantic Web – ISWC 2011 (pp. 193–208).
TL;DR:
This paper proposes a context-aware approach for keyword query interpretation that personalizes the interpretation process based on a user's query context and outperforms the state-of-the-art technique on both efficiency and effectiveness, particularly for ambiguous queries.

An Intermediate Algebra for Optimizing RDF Graph Pattern Matching on MapReduce
In The Semanic Web: Research and Applications (pp. 46–61).
TL;DR:
This paper proposes an approach for optimizing graph pattern matching by reinterpreting certain join tree structures as grouping operations which enables a greater degree of parallelism in join processing resulting in more "bushy" like query execution plans with fewer Map-Reduce cycles.

CoSi
Proceedings of the 20th international conference companion on World wide web - WWW '11.
TL;DR:
The demo will present CoSi, a system that enables context-sensitive interpretation of keyword queries on RDF databases that captures a user's querying context from their query history and shows how context is utilized to influence the interpretation of a new query.
