We present noWorkflow, an open-source tool that systematically and transparently collects provenance from Python scripts, including data about the script execution and how the script evolves over time. During the demo, we will show how noWorkflow collects and manages provenance, as well as how it supports the analysis of computational experiments. We will also encourage attendees to use noWorkf...

We present the SPIN system, a computational tool to detect linguistic and dialog structure patterns in a social interaction that reveal the underlying power relations between its participants. The SPIN system labels sentences in an interaction with their dialog acts (i.e., communicative intents), detects instances of overt display of power, and predicts social power relations between its partic...

Citizen sensing, with a billion plus active users and billion plus tweets/week, is complemented by shared information from contextually relevant Web of Data (blogs, news, and media objects) and background knowledge. How can these enable us in informing, understanding and managing a broad variety of activities and events locally and around the world? Twitris, currently in version 3, is a scalabl...

Background Although there has been a favorable trend in the Infant Mortality Rate in India in the last decade, the country is still unlikely to meet the Millennium Development Goal #4. Of significance, there has been minimal improvement in the early neonatal mortality rate, which is an indicator of quality of perinatal care. In the efforts to address this aspect, a range of efforts and interven...

While individual components for semantic data integration are commonly available, end-to-end solutions are rare. We demonstrate DataOps, a seamless Anything-to-RDF semantic data integration toolkit. DataOps supports the integration of both semantic and non-semantic data from an extensible host of different formats. Setting up data sources end-to-end works in three steps: (1) accessing the data ...

In this paper, we present the system design and the key techniques of our mobile robot platform called KeJia-LC, who won the first place in the demo challenge on Benchmarkinng Service Robots in RoboCup 2015. Given the fact that KeJia-LC is a low-cost version of our KeJia robot without shoulder and arm, several new technical demands comparing to RoboCup@Home are highlighted for better understand...

In two previous essays (Perron, 2006 and Arsenault & Perron 2008), I have conceptualized the partaking in a game as a cognitive frame, as an ongoing process. To explain the gamer's immersion and progression through a game, I have resorted to the figure of the cycle, of the spiral instead of talking about Huizinga's " magic circle ". In this model, three interconnected spirals are represented: t...

This work introduces a smart cross-layer architecture composed of a battery-less smart solar power system, a simple configurable power-aware MAC protocol, and an intelligent fuzzy-logic based autonomous configuration protocol. The design of the proposed protocols is derived from the fundamental principles of complementary areas, namely: electronics, protocol engineering, and artificial intellig...

OLAP servers based on relational backends typically exploit materialized aggregate tables to improve response times of complex analytical queries. One of the key problems in this context is the view selection problem: choosing the optimal set of aggregation tables (called configuration) for a given workload. In this paper, we present a system that continuously monitors the workload and raises a...
