Our iU nit retrieval module first used inverted query frequency (iqf) to extract topic-related keywords, and then identify impor tant nuggets by measuring and sorting nf·iqf scores, where nf is nugget frequency. Summarization module is a greedy clustering system according to the lengths and sizes of com mon leading substrings among iUnits. Our iUnit Retrieval formal run did not perform well, where nDCG@10 score is 0.1426 and Q@10 is 0.0803. But our iUnit Summarization formal run was ranked at the first place, where M-measure score is 4.43 at the patience parameter L=280. |
