## Training queries for NTCIR-15 Data Search |
|
|
|
- `data_search_j_train_topics.tsv` (Japanese subtask) |
|
- `data_search_e_train_topics.tsv` (English subtask) |
|
- Training queries, by which participants are expected to develop systems. |
|
- Each line contains an ID and a query string separated by TAB |
|
|
|
|
|
## Test queries for NTCIR-15 Data Search |
|
|
|
- `data_search_j_test_topics.tsv` (Japanese subtask) |
|
- `data_search_e_test_topics.tsv` (English subtask) |
|
|
|
|
|
## Training qrels for NTCIR-15 Data Search |
|
|
|
Relevance judgments for training queries. |
|
|
|
- `data_search_j_train_qrels.txt` (Japanese subtask) |
|
- `data_search_e_train_qrels.txt` (English subtask) |
|
- The same format as that used in the NTCIR WWW tasks |
|
- `[QUERY_ID] [DOC_ID] [REL_LEVEL]` |
|
- e.g. `DS1-J-0002 000031519435 L2`, meaning that dataset `000031519435` is highly relevant (`L2`) for query `DS1-J-0002`. |
|
|
|
|
|
## Test qrels for NTCIR-15 Data Search |
|
|
|
Relevance judgments for test queries. |
|
Documents from the official runs were judged. |
|
|
|
- `data_search_j_test_qrels.txt` (Japanese subtask) |
|
- `data_search_e_test_qrels.txt` (English subtask) |
|
|
|
|
|
## Extra Qrels for NTCIR-15 Data Search |
|
|
|
Relevance judgments for test queries. |
|
Documents from the extra runs were judged. |
|
|
|
- `data_search_j_extra_qrels.txt` (Japanese subtask) |
|
- `data_search_e_extra_qrels.txt` (English subtask) |
|
|
|
|
|
## All Qrels for NTCIR-15 Data Search |
|
|
|
These are sets of qrels including the test qrels and extra qrels. |

|
|
|
|
|
## Training queries for NTCIR-16 Data Search |

More precisely, `data_search_2_*_train_topics.tsv` is a union of |
|
`data_search_*_train_topics.tsv` and `data_search_*_test_topics.tsv`. |
