The abstract is below:

A key challenge in contemporary ecology and conservation is the accurate tracking of the spatial distribution of various human impacts, such as fishing. While coastal fisheries in national waters are closely monitored in some countries, existing maps of fishing effort elsewhere are fraught with uncertainty, especially in remote areas and the High Seas. Better understanding of the behavior of the global fishing fleets is required in order to prioritize and enforce fisheries management and conservation measures worldwide. Satellite-based Automatic Information Systems (S-AIS) are now commonly installed on most ocean-going vessels and have been proposed as a novel tool to explore the movements of fishing fleets in near real time. Here we present approaches to identify fishing activity from S-AIS data for three dominant fishing gear types: trawl, longline and purse seine. Using a large dataset containing worldwide fishing vessel tracks from 2011–2015, we developed three methods to detect and map fishing activities: for trawlers we produced a Hidden Markov Model (HMM) using vessel speed as observation variable. For longliners we have designed a Data Mining (DM) approach using an algorithm inspired from studies on animal movement. For purse seiners a multi-layered filtering strategy based on vessel speed and operation time was implemented. Validation against expert-labeled datasets showed average detection accuracies of 83% for trawler and longliner, and 97% for purse seiner. Our study represents the first comprehensive approach to detect and identify potential fishing behavior for three major gear types operating on a global scale. We hope that this work will enable new efforts to assess the spatial and temporal distribution of global fishing effort and make global fisheries activities transparent to ocean scientists, managers and the public.

A team of 3 students from the Institute for Big Data Analytics have walked away with the prize of the "Most Innovative Use of Big Data", and a cheque for $800 from the Sports Hack 2015 competition, held Nov 27-29th in Vancouver, Toronto and Halifax and sponsored by a range of big name tech companies, universities and the CFL.  Forty-one teams competed in the challenge to produce an app to encourage fan engagement using datasets from the CFL.  Our team created an app that tracked the Tweets of CFL fans providing them with rankings of their activity levels and a points system to reward their activity and their participation in mini-games about the football matches, making use of both machine learning techniques and sentiment analysis.  The app could also provide CFL organizations with information about their fans activities and locations and provide the opportunity to advertize to fans, to convert fan points into merchandise of the organizations or their sponsors.  It would be fan-centric rather than team-centric .  The contest was a big challenge, given the hard work, the lack of sleep, and the tight competition.

Congratulation to Masters student Hossein Sarshar and Research Assistant Pedram Adibi from the Institute for Big Data Analytics, and their colleague, Dalhousie alumnus Mehran Zamani, who, as Team Sol-Ops, won first prize in the Smart Energy Apps Challenge sponsored by Innovacorp, HRM, NSCC, Shiftkey Labs and Dalhousie University.  The challenge was to create an app which made use of the data collected by Halifax Solar City on a number of parameters relating to installed solar hot water systems.  Team Sol-Ops created an app which made use of techniques of computer science, data science and engineering to provide customers with an analysis of their usage of hot water, and recommendations for changing that behaviour to maximize the environmental and economic benefits they could receive from their systems.  It took 6 weeks to create the winning app, beating 10 other teams and claiming the $6000 first prize.  Success in the competition may also be the stepping stone to other opportunities as the team finds themselves in conversations with investors and other organizations who are taking in interest in the commercial potential of their creation.

Rob Warren gave a talk on the Panel on Linked Open data at the Digital Humanities Conference, Sydney Australia, June 29 - July 3. 

His paper explored the notion of place, feature and geometry in the context of the Great War using Linked Open Data. In previous works, the translation of obsolete military coordinates through API’s (Application Program Interface) was previously covered. He reviewed their use as an efficient and effective means of indexing archival documents about the war. Most war diaries, operations orders and dispatches in British and Dominions records refer to locations using both named features and coordinates. This permits the geo-referencing of each statements within a document to find the current location in question while segmenting the document according to different spatial component.

Data-Driven Augmented Reality for Museum Exhibits and Lost Heritage Sites.
Museums on the Web 2015 (http://mw2015.museumsandtheweb.com/)
Palmer House Hilton, Chicago, IL, USA
April 8-11, 2015

We review the possibilities, pitfalls, and promises of recreating lost heritage sites and historical events using augmented reality and "Big Data" archival databases. We define augmented reality as any means of adding context or content, via audio/visual means, to the current  physical space of a visitor to a museum or outdoor site. Examples range from simple prerecorded audio to graphics rendered in real time and displayed using a smartphone.

Previous work has focused on complex multimedia museum guides, whose utility remains to be evaluated as enabling or distracting. We propose the use of a data­-driven approach where the exhibits' augmentation is not static but dynamically generated from the totality of the data known about the location, artifacts, or event. For example, at Bletchley Park, reenacted audio conversations are played within rooms as visitors walk through them. These can be called "virtual contents," as the audio recordings are manufactured. Given that a number of documentary sources, such as meeting minutes, are available concerning the events that occurred within the site, a dynamic computer-generated script could add to the exhibits.

Visitors' experiences can therefore react to their movements, provide a different experience each time, and be factually correct without requiring any expensive redesign. Furthermore, the use of a data-driven approach allows for the updating of exhibits on the fly as researchers create or curate new data sources within the museum. If artifacts need to be removed from an exhibit, pictures, descriptions, or three-dimensional printed copies can be substituted, and the augmented reality of visitor experience can adapt accordingly.
