Top-k Relevance Comparison
How do we rank tweets considering
trustworthiness and relevance?
Surface web uses hyperlink analysis
between the pages.
Twitter consider retweets as “links”
between the tweets for ranking.
Retweets are sparse, and often planted or
passively retweeted.
Build Implicit links
between the tweets
containing the same fact, and
analyze the link-structure.
Agreement-edge weights between
the tweets are computed using the
Soft TF-IDF with Jaro-Winkler
Ranking-score is equal to sum of
the edge weights.
