Determining location-based contextual hashtags

A computer-implemented method to generate a database of hashtags relevant to a place of interest, the computer-implemented method comprising:

• receiving information to identify a physical location for a place of interest and a category of the place of interest;
• determining an automatic hashtag based on the category, wherein the automatic hashtag describes a time-sensitive event;
• determining one or more manual hashtags based on a social post in a social network from a first user that provided the social post when a first user device associated with the first user is within a first threshold distance from the physical location;
• determining one or more query hashtags based on a user query from a second user when a second user device associated with the second user is within a second threshold distance from the physical location;
• storing in a database information about the place of interest, the category, the automatic hashtag, the one or more manual hashtags, and the one or more query hashtags;
• and
• generating a ranked set of hashtags from the database, wherein the ranked set is organized based on the time-sensitive event.

A system to generate a social post that includes hashtags, the system comprising:

• one or more processors;
• a location module stored on a memory and executable by the one or more processors, the location module configured to receive information indicative of a physical location of a first user device associated with a first user, identify a place of interest based on the information indicative of the physical location of the first user device, and determine a category associated with the place of interest;
• a ranking module stored on the memory and executable by the one or more processors, the ranking module configured to generate a ranked set of hashtags, wherein one or more hashtags in the ranked set of hashtags describe one or more events that are time sensitive and the hashtags in the ranked set of hashtags are organized based on the one or more events that are time sensitive;
• and
• a user interface module stored on the memory and executable by the one or more processors, the user interface module configured to provide the ranked set of hashtags and to generate a social post for a social network, the social post including the ranked set of hashtags and information about the place of interest.
