Document/Abstract Pairs to Document/Extract Pairs

• For efficiency and comparisons, for each abstract sentence, select 3 document sentences that probably correspond

• Use Marcu '99 technique:

  • Greedily select three sentences by looking at overlap in vector space model
    • Evaluated in this context, each of 20 were assigned a score of 0 (no connection), 1 (document sentences contain most of the information) or 2 (document sentences contain all of the information)
    • Mean = 1.75 (zero 0s, five 1s, fifteen 2s)
