An Evaluation queue allows for people to submit Synapse Files, Docker images, etc. for evaluation. They are designed to support open-access data analysis and modeling challenges in Synapse. This framework provides tools for administrators to collect and analyze data models from Synapse users created for a specific goal or purpose.
Create an Evaluation Queue
To create a queue, you must first create a Synapse project. To learn how to do so, please follow instructions here. An Evaluation Queue can take several parameters that you can use to fine tune it to your preferences. The minimum requirements to create a queue are:
name – Unique name of the evaluation
description – A short description of the evaluation
contentSource – Synapse Project associated with the evaluation
submissionReceiptMessage – Message to display to users upon submission
submissionInstructionsMessage – Message to display to users detailing acceptable formatting for submissions.
Additionally, you can pass in an optional quota parameter using the R, Python, or web clients. It can be configured with the following terms:
firstRoundStart - The date/time at which the first round begins in UTC
roundDurationMillis - The duration of each round in milliseconds
numberOfRounds - The number of rounds, or null if there is no end
submissionLimit - The maximum number of submissions per team/participant per round. Please keep in mind that the system will prevent additional submissions by a user/team once they have hit this number of submissions.
Note: The name of your evaluation queue MUST be unique, otherwise the queue will not be created.
The example below shows how to create a queue using all of the parameters described:
You can create Evaluation queues on the web by navigating to your challenge site by adding /admin to the url (E.g. www.synapse.org/#!Synapse:syn12345/admin). Click Tools on the right corner and Add Evaluation Queue and follow the prompts.
In the web client, the quota can be modified under the Challenge tab by clicking Edit for the Evaluations that require a quota.
Configure an Evaluation Queue
An Evaluation Queue can have limits. Submission “rounds” (start date, round duration, and number of rounds) with an optional submission quota (maximum submissions per participant or team) can be defined for each queue. There is no way to configure the round or quota settings of an Evaluation Queue from the web. The Evaluation ID can be found under the Challenge tab of your project. Please note that a Challenge tab will not appear on your project until you have created a challenge (Tools > Run Challenge). In the case below, the evaluation queue id is 9610091.
Using this value, we can configure the quota parameters of this evaluation queue with the R or Python client.
Each Evaluation has its own sharing settings, which limit who can interact with the Evaluation and in what way:
“Administrator” sharing should be tightly restricted, as it includes authority to delete the entire Evaluation queue with all its contents. These users also have the ability to download all the submissions.
“Can score” allows for individuals to download all the submissions
“Can submit” allows for Teams or individuals to submit to the Evaluation, but doesn’t have access to any of the submissions.
“Can view” allows for Teams or individuals to view the submissions on a leaderboard.
To set the sharing setting, go to the Challenge tab and see your list of Evaluations. Click on the Share button per Evaluation and share it with the Teams or individuals you would like.
Important: When someone submits to an Evaluation, a copy of the submission is made, so a person with Administrator or Can score access will be able to download the submission even if the submitter deletes the entity.
Submitting to an Evaluation Queue
Any Synapse Entity may be submitted to an Evaluation Queue.
All submissions of an Evaluation queue can be views through the through the use of a leaderboard. To learn how to create a wiki page, please visit here. Below are instructions on how to set up a leaderboard. You must know the evaluation Id to do so; see the section on how to “Configure an Evaluation Queue” for instructions on finding the evaluation Id.
Adding Leaderboard Widget
Configuring Leaderboard Widget
Once you click on Leaderboard, you will have to input your own query statement such as select * from evaluation_9610091. Remember, 9610091 should be replaced with your own evaluation Id. To view all the columns available, click Refresh Columns.
Clicking Refresh Columns will add these default columns.
Saving Leaderboard Widget
If you are happy with your leaderboard configurations, save both the configurations and the wiki page to see the Leaderboard.
