Visual question answering in the medical domain
The ImageCLEF 2018 VQA-Med challenge has officially ended and we would like to thank everyone for their participation. The official results are already emailed to corresponding participants.
Post-challenge submissions and the leaderboard will remain enabled for a few weeks so you will still be able to submit result files and have them continuously evaluated during a limited period. Please consider that in order to see the version of the leaderboard with the post-challenge submissions integrated, you have to turn on the switch Show post-challenge submission right below the leaderboard.
At the same time we’d like to encourage you to submit a CLEF Working notes paper until the end of May.
Please also note that participants registering from now on will not be automatically registered with CLEF anymore.
Note: Do not forget to read the Rules section on this page
With the increasing interest in artificial intelligence (AI) to support clinical decision making and improve patient engagement, opportunities to generate and leverage algorithms for automated medical image interpretation are currently being explored. Since patients may now access structured and unstructured data related to their healthcare utilization via patient portals, such access also motivates the need to help them better understand their conditions in line their available data, including medical images.
Clinicians’ confidence in interpreting complex medical images can be significantly enhanced by “second opinion” provided by an automated system. In addition, patients may be interested in the morphology/physiology and disease-status of anatomical structures around a lesion that has been well characterized by their healthcare providers – and they may not necessarily be willing to pay significant amounts for a separate office- or hospital visit just to address such questions. Although patients often turn to search engines (e.g. Google) to disambiguate complex terms or obtain answers to confusing aspects of the medical image, results from search engines may be nonspecific, erroneous and misleading, or overwhelming in terms of the volume of information.
Visual Question Answering is a new and exciting problem that combines natural language processing and computer vision techniques. Inspired by the recent success of visual question answering in the general domain , we propose a pilot task this year to focus on visual question answering in the medical domain. Given a medical image accompanied with a set of clinically relevant questions, participating systems are tasked with answering the questions based on the visual image content.
The data will tentatively include a training set (5K) and a validation set (0.5K) with medical images accompanied with question-answer pairs, and a test set (0.5K) of images with questions only. To create the datasets for the proposed task, we would consider the medical domain images extracted from PubMed articles (essentially a subset of the ImageCLEF 2017 caption prediction task).
As soon as the submission is open, you will find a “Create Submission” button on this page (just next to the tabs)
-Each team is allowed to submit a maximum of 5 runs. -We expect the following format for the result submission file: <QA-ID><TAB><Image-ID><TAB><Answer>
1 rjv03401 answer of the first question in one single line 2 AIAN-14-313-g002 answer of the second question 3 wjem-11-76f3 answer of the third question
-You need to respect the following constraints:
• The separator between <QA-ID>, <Image-ID> and <Answer> has to be a tabular white space (tab). • Each <QA-ID> of the test set must be included in the run file exactly once. • You should not include special characters in the <Answer> field. • All 500 <QA-ID> and <Image-ID> pairs must be present in a participant’s run file in the same order as the VQAMed2018Test-QA.csv file.
-Participants are allowed to use other resources asides from the official training/validation datasets, however the use of the additional resources must have to be explicitly stated. For meaningful comparison, we will separately group systems who exclusively use the official training data and who incorporate additional sources.
Please provide the necessary information and select a submission file. As soon as a submission file is selected the form is submitted automatically. After the submission of the form the grading process will be initiated where an external grader validates/evaluates the submitted file and eventually returns the score back to CrowdAI. Depending on the file size, the evaluation algorithm and the total grading workload this could take a while. You can see the status of your submission in the “Submissions” tab of this challenge’s page, where you will redirected to automatically after having submitted. In case the evaluation failed, the “Status” field shows “failed” and an error message in the “Message” field is displayed.
Information will be posted soon.
Note: In order to participate in this challenge you have to sign an End User Agreement (EUA). You will find more information on the ‘Dataset’ tab.
ImageCLEF lab is part of the Conference and Labs of the Evaluation Forum: CLEF 2018. CLEF 2018 consists of independent peer-reviewed workshops on a broad range of challenges in the fields of multilingual and multimodal information access evaluation, and a set of benchmarking activities carried in various labs designed to test different aspects of mono and cross-language Information retrieval systems. More details about the conference can be found here .
Submitting a working note with the full description of the methods used in each run is mandatory. Any run that could not be reproduced thanks to its description in the working notes might be removed from the official publication of the results. Working notes are published within CEUR-WS proceedings, resulting in an assignment of an individual DOI (URN) and an indexing by many bibliography systems including DBLP. According to the CEUR-WS policies, a light review of the working notes will be conducted by ImageCLEF organizing committee to ensure quality. As an illustration, ImageCLEF 2017 working notes (task overviews and participant working notes) can be found within CLEF 2017 CEUR-WS proceedings.
Participants of this challenge will automatically be registered at CLEF 2018. In order to be compliant with the CLEF registration requirements, please edit your profile by providing the following additional information:
Regarding the username, please choose a name that represents your team.
This information will not be publicly visible and will be exclusively used to contact you and to send the registration data to CLEF, which is the main organizer of all CLEF labs
Participating as an individual (non affiliated) researcher
We welcome individual researchers, i.e. not affiliated to any institution, to participate. We kindly ask you to provide us with a motivation letter containing the following information:
the presentation of your most relevant research activities related to the task/tasks
your motivation for participating in the task/tasks and how you want to exploit the results
a list of the most relevant 5 publications (if applicable)
the link to your personal webpage
The motivation letter should be directly concatenated to the End User Agreement document or sent as a PDF file to bionescu at imag dot pub dot ro. The request will be analyzed by the ImageCLEF organizing committee. We reserve the right to refuse any applicants whose experience in the field is too narrow, and would therefore most likely prevent them from being able to finish the task/tasks.
ImageCLEF 2018 is an evaluation campaign that is being organized as part of the CLEF initiative labs. The campaign offers several research tasks that welcome participation from teams around the world. The results of the campaign appear in the working notes proceedings, published by CEUR Workshop Proceedings (CEUR-WS.org). Selected contributions among the participants, will be invited for publication in the following year in the Springer Lecture Notes in Computer Science (LNCS) together with the annual lab overviews.
