US-Japan Workshop: June 5 – 6 2017

1st US-Japan Workshop Enabling Global Collaborations in Big Data Research

J.W. Marriott Hotel, Buckhead, Atlanta, GA, USA June 5 – 6, 2017 


Workshop Objective

This workshop will bring together researchers from around the world to discuss experiences, challenges, and opportunities in transnational and international collaborative research on information technology (IT) and IT-supported applications, with focus on active collaborations between the United States (U.S.) and Japan. The workshop will provide opportunities for participants to interact directly and promote collaborative research activities. The collaboration is expected to achieve scientific knowledge that would be difficult to obtain individually.

Workshop attendance will be by invitation only, following response to this call as outlined below. Prospective attendees are expected to be investigators on funded research projects, and should submit papers or whitepaper for consideration by the program committee. Workshop organizers are requesting funding from NSF and JST to support partially the travel costs and registration fees of invited attendees from the U.S. and Japan. Principal Investigators of projects in relevant NSF and JST programs are strongly encouraged to apply. Additionally, early career researchers and underrepresented minorities are encouraged to apply.

Priority Research Topics

Topics of interest for collaboration include, but are not limited to:

  • Big Data Fundamental Technologies and Applications: novel techniques, methodologies, and technologies in computer science, statistics, computational science, and mathematics, together with innovative applications in domain science, which may include, for example, disaster management.
  • Smart and Connected Communities (SCC): strongly interdisciplinary, integrative research that will improve understanding of smart and connected communities and lead to discoveries that enable sustainable change to enhance community functioning.
  • Cyber-Physical Systems (CPS) and Internet of Things (IoT): system science needed to engineer complex, reliable cyber-physical systems that people can use, interact with, and depend upon, namely the cross-cutting fundamental scientific and engineering principles that underpin the integration of cyber and physical elements across all application sectors.
  • Artificial Intelligence and Machine Learning: research enabling computational understanding and modeling of intelligence in complex, realistic contexts, or more generally, processing and functionality to address data of unprecedented scale, complexity, heterogeneity, etc.

April 2016 Kumamoto Earthquakes

There was a more powerful earthquake in Kumamoto at 01:25 on Saturday April 16, 2016, a day after an earlier tremor killed nine people.

Our tool collected the data about this event from social networks, such as Twitter, YouTube, and Instagram. The following videos, images, links, and events are from the data collected by the tool.

Landslide blocks Batote – Kishtwar highway

Mar 13 2016

“The Batote- Kishtwar Highway, connecting twin districts of Doda and Kishtwar with rest of the state, was closed again on Sunday morning when a huge landslide blocked the road at Ragi-Nullah – 21 km from Doda.

After remaining closed for 18 hours due to landslide and shooting stones at half-a-dozen places, the road was opened for traffic yesterday afternoon.

Today morning, a massive landslide and a huge boulder blocked the road near Ragi-Nullah on Batote-Doda stretch.

More than 150 passenger vehicles and those carrying essential commodities were stranded on both sides of the highway.”

A new publication by GRAIT-DM team has been added

We added a new book chapter “Multi-hazard Detection by Integrating Social Media and Physical Sensors” developed by the GRAIT-DM team and published by Springer: see the Publications section of the portal.

Here is the abstract from the book chapter:
Disaster Management is one of the most important functions of the government. FEMA and CDC are two examples of government agencies directly charged with handling disasters, whereas USGS is a scientific agency oriented towards disaster research. But regardless of the type or purpose, each of the mentioned agencies utilizes Social Media as part of its activities. One of the uses of Social Media is in detection of disasters, such as earthquakes. But disasters may lead to other kinds of disasters, forming multi-hazards such as landslides. Effective detection and management of multi-hazards cannot rely only on one information source. In this chapter, we describe and evaluate a prototype implementation of a landslide detection system LITMUS, which combines multiple physical sensors and Social Media to handle the inherent varied origins and composition of multi-hazards. Our results demonstrate that LITMUS detects more landslides than the ones reported by an authoritative source.

LITMUS: Landslide Detection by Integrating Multiple Sources

A new paper has been added to the Publications page: “LITMUS: Landslide Detection by Integrating Multiple Sources” by our team of Aibek Musaev, De Wang and Calton Pu. We will be presenting it at the ISCRAM conference later this year. In this paper, we evaluate a landslide detection system LITMUS, which combines multiple physical sensors and social media to handle the inherent varied origins and composition of multi-hazards. LITMUS integrates near real-time data from USGS seismic network, NASA TRMM rainfall network, Twitter, YouTube, and Instagram. The landslide detection process consists of several stages of social media filtering and integration with physical sensor data, with a final ranking of relevance by integrated signal strength.
