Unusual events in life are often the events we
treasure, find interesting and consequently share
with friends. We present a behavioral method to
identify unusual blog entries within a blog by
evaluating comment senders’ behaviors. Reader
Feedback Vector (RFV) represents each blog entry
with a comment sender properties vector and
examines each vector for any indication of abnormal
comment sender behaviors. An Intimacy Score,
which measures the “friendship” level between each
comment sender and blogger, is used to weigh each
comment sender’s properties. This ensures that
comment senders who are deemed more “intimate”
with the blogger are evaluated more importantly.
RFV is subjected to a human-based analysis which
asks each test subject to compare the results from
RFV to the results from a text-based approach. A
second similar test evaluates the significance of
Intimacy Score by comparing RFV with and without
Intimacy Score (RFV-IS vs. RFV). RFV-IS performed
better, by returning more unusual blog entries than
its counterpart. |
