for each of the new comments, add, based on the analyzing, the new comment to one or more of a plurality of collections of comments;
identify active collections of the plurality of collections, active collections including at least one new comment;
calculate, for each active collection, a first measure of semantic similarity between the collection and the remaining active collections of the live chat stream;
calculate, for each active collection, a second measure of semantic similarity between the active collection and non-active collections of the live chat stream;
calculate, for each active collection, a third measure of semantic similarity between the active collection and historical collections of comments for one or more prior sessions of the live chat stream;
determine, for each active collection, a semantic-uniqueness score based on the first, second and third measures of semantic similarity;
determine, for each active collection, an activity score representing an activity level of the active collection for the current session of the live chat stream;
determine, for each active collection, a final importance score based on its semantic-uniqueness score and activity score; and
control the display of each active collection based on its final importance score.
