Thanks to
          for the data and ROUGE =p
Effect of Sentence Filtering
    choosing the top 10 sentences

                D0701A        D0720E

#Event before
                 3320          1435
   Filtering
 #Event after
                  67            37
   Filtering


How can we represent 3320 events
         on a timeline?
Time-Event Anchoring
                D0701A        D0720E

#Event before
                 3320          1435
  Filtering
   #Failure      3085          1129

 #Event after     67            37
   Filtering
   #Failure       49            29


This shows that my approach is a failure
TARSQI only support
  single document



                        WHY?
e.g. 50 tagged events,     Unable to deduce the
only 50 pairs of          relationships for all pair
relation are tagged               of events
should be 50C2 = 1225

                OR EVEN
          The limit of temporal
                 analysis
cannot get enough information from the documents
cosine similarity with tf-idf
weighting is computational
         expensive
    2.5 hrs for 867 sentences
DUC2007 Documents are
          hard to parse
       different documents have different
                   format........

no standard date format...

                         contains some special
                      characters that cause troubles
                            to XML parsers...
