Polis Opinion Matrix

• comments * participants = a sparse matrix of votes
• Consider an excel table
  • comments are columns, each column represents a statement submitted by a participant
  • participants are rows, each row is the voting record of a participant.
  • Thus, the excel sheet fills with votes by participants on comments
• The resulting sparse matrix, and metadata, are available in the export
• The matrix is said to be sparse because it will (very likely) not be complete — ie., most participants will not vote on most comments.
• 👾 Algorithms and 🔬 Analysis are run on the matrix
• There is no natural language processing involved in the clustering
