Can I download the SHINRA2020-ML task data using my leaderboard account?

To download the SHINRA2020-ML task data, you need to create a SHINRA account apart from the leaderboard account and sign in using the SHINRA account. As for the leaderboard account, please check FAQ on Leaderboard.


The Participant paper due is stated as ’Oct 10, 2020’ in the email from task organizers, while NTCIR-15 site(Important Dates) says it is on ‘Sep 20, 2020’. Which is correct?

’Oct 10, 2020’ is correct. The SHINRA2020-ML Participant paper due has been extended along with the postponement of the SHINRA2020-ML Registration & Result submission deadline.

Target Languages

Do I have to classify all the 30 languages to be a participant?

No. You are expected to select one or more target languages. See CFP for further details.

Training Data

How should I handle the labels from different records sharing the same page ids?

There are cases where multiple records in the training data share the same pageid, which means that the page is linked from multiple Japanese pages.

{"pageid": 57330, "title": "Circulatory system", "ja_pageid": 108191, "ja_title": "循環器", "_stamp": "AUTO.TOHOKU.201906", "ENEs": [{"ENE_id": "0", "ENE_name": "Concept"}]}
{"pageid": 57330, "title": "Circulatory system", "ja_pageid": 569307, "ja_title": "循環系", "_stamp": "HAND.AIP.201910", "ENEs": [{"ENE_id": "", "ENE_name": "Animal_Part"}]}

In such cases, please get the ENE_ids of the page from all the records with the same pageid in the training data.
If you would like to see the relevant data to solve the problem, please refer to the following posts on SHINRA2020-ML slack.
We apologize for the inconvenience.


Can I submit the results after the deadline?

The official results should be submitted by Aug 31 (Timezone: Baker Island(USA), UTC-12).
If you miss the deadline, you can still submit your results. Please notice the followings.

  • The results submitted after the deadline are treated as unofficial. You will get unofficial scores instead of the official evaluation results.
  • We will publish the unofficial evaluation results, which will be clearly distinguished from the official ones.
  • The results will be used for building the knowledge base.
Some portion of the target data is overlapped with the training data. Should we submit the run results for the entire target data?

Yes. Please submit the outputs for the entire target data, though the portion of the target data corresponding to the training data is not used for the evaluation. See SHINRA2020-ML: Results Submission for further details on submission.


Do the official SHINRA2020-ML evaluation and SHINRA2020-ML leaderboard evaluation mean the same thing?

No. The official evaluation of SHINRA2020-ML task is independent of the evaluation of the leaderboard.
The former is based on the entire target data, as described in the SHINRA2020-ML CFP (Task Description), while the latter is based on a portion of the SHINRA2020-ML target data as described in the leaderboard site.
