DH 2015 Chairs’ Welcome
Welcome to the 5th International Conference on Digital Health (www.acm-digitalhealth.org),
held in conjunction with the 24th International World Wide Web Conference (WWW 2015) and
in-cooperation with ACM Special Interest Group on Management of Data (SIGMOD) and Special
Interest Group on Knowledge Discovery and Data Mining (SIGKDD) in Florence, Italy from 18th
May 2015 until 20th May 2015.
The 5th International Conference on Digital health 2015 is building on the great success of the 14th International conference on eHealth series (http://www.electronic-health.org/) featuring
events in London in 2008, Istanbul in 2009, Casablanca in 2010 and the 4th eHealth 2011 taking
place in Malaga with high profile presence from WHO and ECDC. It further follows on the
International Workshop on Public Health in the Digital Age (1st PHDA 2013 and 2nd PHDA
2014) building a community of public health informatics professionals. With ACM support,
collocation with WWW 2015 and expanded programme, the rebranded 5th DH 2015 promises to
deliver a prime international interdisciplinary event bringing together frontline public health
professionals and computer science researches in data mining, crowdsourcing and Big Data
analysis for public health surveillance. To better embrace the growing digital health domain, the
5th DH 2015 is organized into more independent Tracks with proceedings printed by ACM Digital
Library.
Collocation with WWW 2015 promises to attract computer scientists to public health data
management and analytics challenges, we are also inviting a wider industry, start-ups and medical
audience. Keynote speakers include Alberto Sanna, the Director of eServices for Life and Health,
Scientific Institute San Raffaele, Italy will deliver a talk on “Engineering Awareness: Health &
Wellbeing Services in Socio-technological Ecosystems”. We have a great academic programme
including 16 full papers, 14 extended medical abstracts, and 24 posters and a lineup of industry
and healthcare speakers confirmed.
The DH 2015 conference is following its predecessors on social media. You can follow our
Twitter account (@eHealthconf) for the latest updates. We welcome online discussion and
feedback – the official hashtag for the conference is #DH2015. We also have a Facebook page at
http://www.facebook.com/eHealthConf. And please take a look at our Flickr page for the poster
presentations at http://www.flickr.com/groups/digitalhealth2015/.
This year we are repeating a very popular evening – the “Speed Networking” event to bring
together the academic, industry, start up and medical audiences in an effective and enjoyable way.
Finally, we would like to thank to everyone who contributed to the 5th International Conference in
Digital Health 2015 ensuring the event will be a success: authors of the submitted papers, posters
and demos, speakers, the Track Chairs and programme committee members, reviewers and session
chairs and above all the WWW Chairs for offering us to collocate the event. In particular, we are
grateful to Stefano Leonardi, the WWW 2015 & DH 2015 Liaison Chair, for his support and
collaboration, the OIC for sponsoring the conference and ACM for printing the proceedings.
