Some words about context

In the field of ecology and biodiversity, the increase in data acquisition frequencies (field observations, optical sensors, radar sensors, remote sensing, water quality monitoring systems, automatic or semi-automatic Taxa census, sequencing, genotyping, etc.) has resulted in a considerable accumulation of heterogeneous and dispersed data that need to be organized, documented and sorted for use in research and operational support to the expertise.

The Indexmed consortium, renamed IndexMEED for "Indexing for Mining Ecological and Environmental Data", develops data classification and qualification processes, heterogeneous and remote. These processes make it possible to construct graphs from data on biodiversity and to use them for purposes of indication, decision support and formulation of new scientific hypotheses. The graphs allow to represent and to explore interactions between observation or experimentation objects, measured variables, parameters taken into account.

Graphs are one of the flagship axes for the development of new approaches, integrative analyzes and the representation of complex data for ecological research:

• This integrated tool creates a virtuous circle over the entire data life cycle, since a preliminary qualification of data sets (cleaning, homogenization, information organization, improvement of descriptors) is necessary in order to obtain visual results that can be analyzed;
• It lets you browse the data links and formulate new assumptions, combine objects and explore their statistical relationships.

After two editions devoted to the indexing of data for the purpose of harmonizing information systems while respecting the objectives and the business constraints of the actors, the 3rd days in 2016 of the IndexMEED consortium highlighted this potential of the approaches based on the graphs - already tested in other areas of "big data" - for data mining as well as gaps in skills and experience of the ecology research community to adapt and use these approaches.

On the basis of this observation, the IndexMeed consortium organizes a series of transdisciplinary events in order to:

• Formulate needs in terms of complex analyzes by producers and users of data in the field of ecology and biodiversity;
• Stimulate research in Information and Communication Sciences and Technology (ICST) in order to propose more adequate solutions for the analysis and management of environmental data (spatial and temporal coverage, organizational levels, multi-scale data ...). 

Organisation of the SAGES days

The national Sciences and Algorithms around Graphs in Environment and Societies seminar IndexMeed 2017 is thought as a collaborative space between experts in ecology and biodiversity and experts in the field of ICST, and has the vocation of developing new research based on the approaches related to the graphs, and in particular to construct a project bearing i) on the theoretical aspects (ICST) of algorithms for digging graphs according to scientific questions; and (ii) on the theoretical aspects of integrating heterogeneous environmental data with a view to construct bio-scenarios and to assist in environmental decision-making. This SAGES seminar is open to all.

• The first day will be devoted to the results of the workshops and the exchanges between ecological researchers and researchers in ICST.
• The second day will be devoted to a reflection in the form of workshops concerning the theoretical locks to be lifted (ICST) concerning environmental data, and the elaboration of a response to a call for projects for a specific action on the graphs of environmental data (organised by GDR MaDICS action "GRAMINEES").
• A third day will bring together small group of researchers to structure the response to call for projects according to coherent Work Packages.

Rationales of the SAGES days

Following the successful workshops (2014, 2015 and 2016), this 4th seminar will present the contribution of recent developments about algorithms used to mine graphs for environmental research questions. It will promote exchanges between participants, the acquisition of practical methods and will explore new ways to develop algorithms to mine graphs constructed with heterogeneous environmental data.

The aims, after sharing scientific evidence and confronting experiences, are to develop collaborations using/based on graph approaches and new researches around the Mediterranean Sea and across Europe, and to respond to a European H2020 Call next year. The 3-days program will be extensive, including 4 plenary sessions with keynote speakers (international level), social events, a posters session and 2 workshop (1^st day everybody, 2^nd day only for future task leaders), during which participants will test their first graphs case studies with several algorithms and learn how to choose appropriate methods.
