-Identifying common species
Outcomes
VREVirtual Research Environment.
G. Coro demonstrated the current development version of the VREVirtual Research Environment..
The team was positive about progress made so far. Trends on the basis of absolute Nr of records will be one way but we now need to explore additional methods
T. Webb made suggestions to make it possible to select multiple areas, select by taxonomic group and upload a list of species.
Common species
We had some discussions on the definition of common species. Many factors play a role, such as coverage in time, abundance, geographic spread etc
T. Webb and OBIS are currently exploring alternative ways to identify common species
P. Pagano proposed to look at TF-IDF methods to rank species in datasets, but they need to check how much resources are required to develop this method before they decide to commit in this.
Ways Forward
OBIS will be asked to evaluate the VREVirtual Research Environment. once it is in production mode.
OBIS and T. Webb will continue testing their methods on selecting common species and see if they produce any meaningful results
If these additional methods prove to be a value the specifications will be shared with the development team to implement it in the VREVirtual Research Environment.
CNR will consider the suggestions from T. Webb to improve the VREVirtual Research Environment. functionalities.
