Technology is discussed herein for identifying comparatively trending topics between groups of posts. Groups of posts can be selected based on parameters such as author age, location, gender, etc., or based on information about content items such as when they were posted or what keywords they contain. Topics, as one or more groups of words, can each be given a rank score for each group based on the topic's frequency within each group. A difference score for selected topics can be computed based on a difference between the rank score for the selected topic in each of the groups. When the difference score for a selected topic is above a specified threshold, that selected topic can be identified as a comparatively trending topic. |

1. A method, performed by a computing system, for identifying comparatively trending topics, comprising:
receiving, as post parameters to a interface of the computing system, one or more parameters that distinguish social media postings; obtaining, over a network and based on the received post parameters, two groups of posts; generating a first ranked list of topics for a first group of the two groups of posts by:
identifying, as first group topics, topics from the first group of posts wherein members of the first group topics each comprise one or more words; andcomputing a first rank score for each of the topics of the first group topics; generating a second ranked list of topics for a second group of the two groups of posts by:
identifying, as second group topics, topics from the second group of posts wherein members of the second group topics each comprise one or more words; andcomputing a second rank score for each of the topics of the second group topics; associating, with a selected one of the first group topics from the first ranked list of topics, a difference score computed, by the computing system, as a difference between:
the rank score for the selected one of the first group topics, anda corresponding rank score determined based on the second ranked list of topics; comparing the difference score to a specified threshold; in response to determining that the difference score is above the specified threshold, identifying the selected one of the first group topics as a comparatively trending topic. |
