Abstract: This paper introduces a system for visualization and analysis of geo-spatial and temporal data from call center and microblog sources. The system provides a streaming client for interacting with the data in real time. The system presents the data in a partitioned format using coordinated visualizations
that allows the analyst to view the data in multiple dimension
simultaneously. This allows the user to see patterns that occur in space and time. This project was developed in response to the VAST 2014 Mini-Challenge 3.

Trobades de Salut Pública: Les vacunes: Quines? Drets i deures. – 15 de desembre del 2016

Duncan McLaren- A Case for Truly Smart and Sustainable CitiesOuiShare
Based on research for our MIT book “Sharing Cities”, this presentation argues the case for cities to harness sharing for justice and sustainability. I will highlight the failings of economic framings of sharing and smartness, which position commercial intermediaries as the go-to experts on sharing; rather than the cities, charities and communities that have much longer and deeper experience in managing shared resources, spaces, infrastructures, facilities and services.
Such framings also underlie fruitless polarized public debate over the potential and role of commercial sharing platforms such as Uber and Airbnb. Genuine sharing cities need to both enable and regulate the collaborative economy. But they also have the power and opportunity to harness the potential of sharing to rebuild social capital and a shared urban commons. I will outline ways in which cities that open themselves to cultural and political disruption can flourish by engaging with the rich diversity of sharing practices and organisations that are enabled by modern technologies and collective values.

Slides: Safeguarding Abila through Multiple Data PerspectivesParang Saraf
Abstract: This paper introduces a system for visual analysis of news articles, emails, GPS tracking data, financial transactions and streaming micro-blog data. The system was developed in response to the 2014 VAST Grand Challenge and comprises of several interfaces for mining textual, network, spatio-temporal, financial, and streaming data.

EMBERS AutoGSR: Automated Coding of Civil Unrest EventsParang Saraf
Abstract: We describe the EMBERS AutoGSR system that conducts automated coding of civil unrest events from news articles published in multiple languages. The nuts and bolts of the AutoGSR system constitute an ecosystem of filtering, ranking, and recommendation models to determine if an article reports a civil unrest event and, if so, proceed to identify and encode specific characteristics of the civil unrest event such as the when, where, who, and why of the protest. AutoGSR is a deployed system for the past 6 months continually processing data 24x7 in languages such as Spanish, Portuguese, English and encoding civil unrest events in 10 countries of Latin America: Argentina, Brazil, Chile, Colombia, Ecuador, El Salvador, Mexico, Paraguay, Uruguay, and Venezuela. We demonstrate the superiority of AutoGSR over both manual approaches and other state-of-the-art en- coding systems for civil unrest.

The criticality of NGO role in India is felt when the figures of poverty, hunger, malnutrition and illiteracy glare at our face. The Akshaya Patra in Bangalore is one among the many NGOs playing a pivotal role.
从学术典藏库(IR)到当前科研信息系统(CRIS) [Moving from an IR to a CRIS (Current Research Info...David T Palmer
IRs collect, manage and display publications, and their metadata. However, an institution’s research, expertise and capacity is described by more than publications. The HKU Scholars Hub, hosted in DSpace, began as the IR of The University of Hong Kong (HKU) in 2005. Asking for voluntary deposit of publications from HKU academics, it received little notice, and more importantly, little support from University senior management. In 2009 a new HKU initiative, Knowledge Exchange, adopted the Hub as a key vehicle to share knowledge and skill with the community outside HKU. With funding support from the Office of KE, we extended the data model of DSpace to include relational tables on non-publication objects, including people, grants, and patents, holding attributes of these objects, such as co-investigators, co-inventors, co-prize winners, research interests, languages spoken, supervision of postgraduate theses, etc. The DSpace user interface now delivers an integrated search and display on these objects and attributes, as well as on ones newly derived, such as authority work on name disambiguation and synonymy in Roman and Hanzi (漢字), visualizations on networks of co-authors, co-investigators, etc, metrics extracted from external sources such as Scopus, WoS, PubMed, Google Scholar Citations, internal alt-metrics of view and download counts, and more. Beyond the functions of an IR, the Hub now performs as a system for reputation management, impact management, and research networking and profiling -- all of which are concepts included in the broad term, “Current Research Information System” (CRIS). These new objects and attributes curated from several trusted sources, and integrated into the present mashup, contextualize and highlight HKU research, and attract more hits, than an IR with only publications. The HKU Office of Knowledge Exchange has now funded the modularization of these new HKU features of DSpace. Together with our partner, CINECA of Italy, we are making this work available in open source for the DSpace community.
