1. A computer-implemented method for category based navigation for a primary user, the method comprising: determining a set of relevant users, the relevant users being users deemed, by a computer evaluation process, to be relevant to the primary user, wherein the set of relevant users is a subset of data representing a plurality of users; obtaining, at a server computer, user data related to the set of relevant users; storing the user data at the server computer in a user database, wherein the user data base includes user data of other users of the plurality of users; obtaining entity data from one or more data sources, wherein the entity data is associated with an entity in a plurality of entities, wherein the entity is associated with the target user; storing the entity data at the server computer, wherein the entity data associated with the plurality of entities is stored in an entity database; determining, at the server computer, a set of relevant entities comprising one or more entities relevant to the primary user based on the entity data and user data; categorizing the set of relevant entities with an initial categorization; displaying, on a user device, at least an indication of the initial categorization to the primary user; obtaining, via the user device, user feedback related to the initial categorization; adjusting the initial categorization based on the user feedback to form an adjusted categorization and an adjusted order of relevance; displaying the adjusted categorization and the adjusted order of relevance to the primary user; and obtaining, from the primary user, a response to the categorization of entities in the set of relevant entities via the user device.
