A talk from 2018 RIGA COMM conference where I cover algorithms we developed to create recommendation system for Latvian e-index. The Latvian e-index is an e-environment rating (level/quality of e-services) in public administration institutions and municipalities. Created and calculated by Ministry of Environmental Protection and Regional Development of the Republic of Latvia (VARAM). In talk I give brief overview of recommendation systems and what approaches those can take, how to consider which ones work in your case and why none of typical approaches doesn't work in this case. Then I present the approach we developed.
