This work constitutes progress toward the development of a knowledge base for braids, knots, and their colourings. The main result of this development is the creation of a logical model for storing data pertaining to braids, two-dimensional projections of three dimensional knots, finite quandles, and colorings of braids and knots by quandles. It uses the Entity Relationship data reference model as its starting point and makes the original design there. In addition, it includes a conversion of the Entity Relationship Diagram (ERD) to SQL queries that define tables corresponding to the ERD entity sets. Finally this work demonstrates how to …

Social media specifically has grown in prominence and become a forum for political debate. This project quantitatively analyzes political twitter data and leverages machine learning techniques such as Naive-Bayes to model election results. …
