SemaGrow 2nd Hackathon - Introductory Course

It seems like it has been ages since I last participated in an event; in fact it has been only one month since my participation in the "Agriculture for Life, Life for Agriculture" International Conference. This time I was invited to give a presentation on Agricultural and Food Safety Data in the context of the 2nd SemaGrow Hackathon. The Hackathon was organized by Agro-Know, a partner of the SemaGrow project, and hosted by the Institute of Informatics and Telecommunications (also a partner of the SemaGrow project) of NCSR Demokritos, and took place between 4-7/7/2014 (the full program is available here). There is also some information about the Hackathon at the Agro-Know wiki.

The Hackathon was conveniently collocated with the International Research-Centered Summer School in Cognitive Systems and Interactive Robotics, Data and Content Analysis (IRSS 2014), a fact that allowed the participation of a high number of people with technical background and skills. It was attended by about 40 people from various countries all over the world. My involvement was focused only on the first, introductory day of the event but I am sure that there will be a number of interesting outcomes coming out of the hackathon.

Introduction to Agriculture & Food Safety Data from Vassilis Protonotarios

My presentation was mostly based on existing material, reusing slides from presentations prepared by Nikos and Giannis for related purposes; I just had to update some parts and slightly adapt it in order to meet the requirements of the specific audience. Despite the fact that I know the subject pretty well (I have been working with agricultural data and data sources for the last 4-5 years), it did not make sense to me to leave these nice slides aside and prepare something from scratch. It seems that the presentation was well-accepted by the participants, as I received some nice feedback and it managed to raise some interest, leading to interesting discussions with some of them.

Intro Course to Big Data / "Introduction to Data Science for Agriculture"

The course "Introduction to Data Science for Agriculture", was held on Friday, November 29th, 2013 at the Institute of Informatics & Telecommunications (IIT) of the National Center for Scientific Research (N.C.S.R.) Demokritos, in Athens, Greece. It was the first part of a modular event which also consists of the following parts:

• a Training Day which will be held on Thursday, December 12th, 2013 at the same venue, during which the participants will be trained on the tools and technologies to be used during the Athens Green Hackathon 2013 and
• Athens Green Hackathon 2013, which will take place from Saturday, December 14th, 2013 to Sunday, December 15th, 2013 at the coLab Workspace in Athens, Greece.

You can find more information about the events at the Agro-Know wiki page.

Dr. Vangelis Karkaletsis (NCSR Demokritos)

The course started with an introduction by Dr. Vangelis Karkaletsis, Research Director of IIT of NCSR Demokritos, who provided an overview of the event and the background of IIT, followed by Angeliki Papageorgiou (Agro-Know Technologies, the organizer and contact person for the event) who explained the structure of the modular event and explained all necessary practicalities. The participants (about 35 people) had the opportunity to introduce themselves and explained why they chose to apply for the specific course. I was amazed by the fact that people with so different educational backgrounds were interested in the specific course; starting with agronomists, there were also mathematicians,statisticians, chemists and biologists, as well as web and software developers, ICT specialists and managers. This is exactly the audience that was needed for providing a trans-disciplinary dimension to the issue that we need to address during the hackathon; combining people with expertise in so different domains will surely provide really interesting ideas and outcomes for the hacking!

Antonis Koukourikos (NCSR Demokritos)

The first presentation came from Antonis Koukourikos (Research Associate of NCSR Demokritos), who provided an interesting introduction to big data and their connection to linked data / semantic web. The case of the POWDER (Protocol for Web Description Resources), a protocol for publishing descriptions of (e.g. metadata about) Web resources using RDF, OWL, and HTTP developed by the IIT team and currently used in the SemaGrow project was also discussed.

Me, presenting the Drivetrain approach

The next presentation was delivered by me and discussed about data products and how they can be designed using a specific approach called "Drivetrain approach", also including a number of application case studies (outside the agricultural sector). My presentation was heavily based on an excellent report titled "Big Data Now" (2012) by O' Reilly, which as an amateur in the field of Big Data found excellent for providing an introduction. Related information can also be found in the O'Reilly web site, in the form of an easy-to-read article.

Designing Data Products from Vassilis Protonotarios

Dr. Charalampos Thanopoulos (AK)

The last presentation of the first day was delivered by my colleague in Agro-Know, Dr. Charalampos Thanopoulos, who discussed the issue of big and open data in agriculture. In addition, he provided a number of cases where data problems in agriculture were addressed with the use of the Drivetrain aproach. His presentation included really interesting data coming from various sources, as well as some nice case-studies of Greek companies activated in the agricultural sector.

After a short lunch break, it was time for the Creativity Workshop (an interactive session) on the development of (big) data products: Using the cases of Apivita and Stevia Hellas (two Greek companies) as a basis, participants were divided in two groups led by Angeliki and Babis respectively and were asked to provide ideas on the development of added value data services for the two companies, focusing on their websites. The session consisted of three parts:

1. Identification of data types and formats which might be useful for each case;
2. Discussion of current issues or ideas for improvement, in the form additional services for the customers of the two companies;
3. Development of one idea per team (each group was divided in teams of 2-3 people), based on the ones already discussed. Design was depicted in A4 papers (initially) and flipchart sheets (at a later stage);
4. Presentation of each team's idea to the participants of the event.

Participants of the Intro Course

During the Creativity Workshop 

Overall, I found it to be a really interesting experience, especially taking into consideration that this was my first presentation on big data. I really enjoyed discussions with participants, who brought fresh ideas and different approaches to the event. It was also really nice to see my colleagues Andreas Drakos (facilitating the interactive session) and Elena Kokoliou (documenting the process and supporting the organization) during the course, as their help and contributions were really valuable. I would also like to highlight the participation of Anne Bruinsma from the Netherlands who made this long trip in order to participate and explore opportunities for affiliation and future collaboration.

VOA3R 7th project meeting - Joint session with SemaGrow

Just 15 days before its official end, VOA3R held its 7th and last project meeting at the FAO Headquarters in Rome, Italy between 14 & 15 of May 2013. As usually, all Work Packages were discussed in terms of their status (including each one of the individual pending deliverables) and actions to be taken by the end of the project were also defined and discussed. Everything should be ready before the 2nd (and last) Review Meeting of the project, which will be held on July 18th, 2013 at Brussels, Belgium.

Not only has VOA3R a revised website, but there have been revisions in the VOA3R portal as well, including a change in the URL. The new one is much easier to remember: http://www.voa3r.org!
Among the revisions in the portal the major ones are related to the improvement / refinement of the search mechanisms, as well as bug fixes and usability issues.

I also had the opportunity to participate in the first day of the SemaGrow project meeting on Monday morning, which took place at the premises of Tor Vergata University, quite far from the center of Rome - it was expensive reaching that and tricky reaching the center of Rome after the end of the meeting. I had the opportunity to meet colleagues from UAH (Miguel-Angel and Jaakko), NCSR (Pythagoras) and of course meet new people as always, like Vangelis and Caterina. I was mainly interested in the data sources for this project, as this is a task that I am closely following and contributing to.

SemaGrow held a joint session with VOA3R partners, during which both presentations and interactive sessions took place. During this interactive session we had the chance to provide some ideas for enhancing the tools and services provided by VOA3R. This session also provided me with a unique opportunity to get to meet +Stefano Anibaldi for the first time, after spending hours in Flash and Skype meetings and exchanging numerous emails about various topics - he is always an excellent source of useful information and always willing to help!

This was my first time in Rome (3rd time in Italy though, after my participation in project related events at Teramo and Pollenzo) and I really enjoyed that. I stayed at a lovely B&B near Termini station, so I was only 3 stops away from the meeting place. We also enjoyed a nice traditional Italian pizza at a nice traditional place and had the opportunity to discuss informally with the project partners.
