a real-time system for gathering, analyzing and understanding what large groups of people think in their own words, enabled by advanced statistics and machine learning.
More specifically, Polis is a platform for a conversation, in which participants submit short text statements, or comments, (<140 characters) which are then sent out semi-randomly to other participants to vote on by clicking agree, disagree or pass. Polis allows conversation owners to create conversations which can seamlessly engage (currently) up to hundreds of thousands or (conceivably) millions of participants.
Polis provides automatic (real-time, web-based report) and CompDem, or your own data scientists, can produce manual (python Jupyter notebooks based) data science analysis of the resulting polis opinion matrix available in the data export. See: services.
