# Introduction - To sense user interests, MOCA uses *Tags*. - Tags are small items of information with well defined semantics. - Each tag is associated with a ***counter***. The counter is used to track how many times the user was tagged or to sum points associated with the tag. - Tags are defined in MOCA Console or by the app. - For example: `Restaurant` `Video Store` `Woman` `Parking` `Gym` - Tags can be attached to specific locations by using beacons or programmatically by API. - Tag counters are used to rank the tags. - MOCA provides the following methods to manipulate Tags.
