Web Search Experiments Using OASIS

Vitaliy Kluev
2002 NTCIR Conference on Evaluation of Information Access Technologies  
The major aim of participating in the Web Retrieval Task was to test OASIS to see how well the system supports Japanese Web search. The 10-gigabyte data set was used in our experiments.  ...  We can compare retrieval results for CLIR [4] and Web task obtained by our system. See Figure 5 . They have to be close to each other because the same indexing technique has been used.  ...  But the outcome of the Web task is worse compared to this one of the CLIR task.  ...
