2) ICDAR2023 Call for Competitions

The ICDAR2023 Organizing Committee invites proposals for competitions that aim at evaluating the performance of algorithms and methods related to areas of document analysis and recognition.

You are cordially invited to submit a proposal, that should contain the following information:

  • Contest title and abstract
  • A brief description of the competition, including what the particular task under evaluation is, why this competition is of interest to the ICDAR community, and the expected number of participants
  • An outline of the competition schedule
  • Description of the dataset to be used, and the evaluation process and metrics for submitted methods
  • The names, contact information, and brief CVs of the competition organizers, outlining previous experience in performance evaluation and/or organizing competitions

The following rules shall apply to the accepted Competitions:

  • The name of competition must be standardized by starting with “ICDAR 2023” e.g. “ICDAR 2023 Competition on …” or “ICDAR 2023 … Competition.”
  • Datasets used in the competitions must be made available after the end of the competitions.  Specifically, the training data and ground truth must be publicly released and there must be a way to evaluate performance on a test set. This could take the form of an evaluation server, or the test data, ground truth, and evaluation script could be made publicly available. In principle, the organizers should submit the dataset to IAPR TC10 or TC11.
  • Evaluation methodologies and metrics used must be described in detail so that results can be replicated later.  Evaluation scripts must be released afterwards.
  • Each competition has to be presented with a poster at a prominent place at the conference venue, and selected competitions will get the chance to be presented orally in the dedicated session mentioned above.
  • Competitions must have a sufficient number of participants to be able to draw meaningful conclusions.
  • Reports (full papers) on each competition will be reviewed and, if accepted (the competition ran according to plan, attracted a minimum level of participation and is appropriately described), will be published in the ICDAR 2023 conference proceedings.
  • Participants should not have access to the ground-truthed test dataset until the end of the competition. The evaluation should be done by the organizers.

Submission Guidelines & Inquiries

All proposals should be submitted by electronic mail to the Competition Chairs (Kenny Davila, Dimosthenis Karatzas, and Chris Tensmeyer) via:


We encourage competitions proposals with a solid plan to remain active and challenging for the community over and above ICDAR 2023

3) ICDAR-IJDAR Journal Track

ICDAR-IJDAR Journal Track Call For Papers of the 17th International Conference on Document Analysis and Recognition August 21-26, 2023 – San José, California, USA

Following a tradition established at ICDAR 2019 and 2021, ICDAR 2023 will include a journal paper track that offers the rapid turnaround and dissemination times of a conference, while providing the paper length, scientific rigor, and careful review process of an archival journal.

The ICDAR-IJDAR journal track invites high-quality submissions presenting original research in Document Analysis and Recognition. Journal versions of previously published conference papers or survey papers will not be considered for this special issue; such submissions can be submitted as journal-only papers via the regular IJDAR process.

Accepted papers will be published in a special issue of IJDAR, and will receive an oral presentation slot at ICDAR 2023. Authors who submit their work to the journal track commit themselves to present their results at the ICDAR conference if their paper is accepted. IJDAR’s publisher, Springer-Nature, will make accepted papers freely available for four weeks around the conference. After this, accepted papers will be available from the archival journal.

Format: Journal track papers submissions should follow the format of IJDAR submissions and the standard guidelines for the journal.

Procedure and Deadlines: While we permit a second round of submissions for the ICDAR-IJDAR journal track for both new submissions and revised papers from the 1st round of submissions, it must be understood by all authors that the full journal review process will be required for all ICDAR-IJDAR track submissions — there is no “short cut.” Papers submitted late in the second round run a risk of the review process not completing in time. In such cases, authors should know that: (1) The submitted paper can still continue under review as an IJDAR paper. (2) The authors always have the option of preparing a shorter version of the paper to submit as a regular ICDAR conference paper.

Questions regarding the status of a paper that is under review for the IJDAR- ICDAR journal track should be directed to Ms. Katherine Moretti @Springer (katherine.moretti@springer.com). The guest editors have full authority to determine that the journal review process will not complete in time, and to decline submissions that arrive too late. In which case they will immediately notify the authors who can decide to leave the paper in the standard journal reviewing system or withdraw their manuscript from the journal.

EXO-POPP project

Optical Extraction of Handwritten Named Entities for Marriage
Certificates for the Population of Paris (1880–1940)
Thanks to a collaboration between specialists in machine learning and historians, the EXO-POPP
project will develop a database of 300,000 marriage certificates from Paris and its suburbs
between 1880 and 1940. These marriage certificates provide a wealth of information about the
bride and groom, their parents, and their marriage witnesses, that will be analyzed from a host of
new angles made possible by the new dataset. These studies of marriage, divorce, kinship, and
social networks covering a span 60 years will also intersect with transversal issues such as gender,
class, and origin. The geolocation of data will provide a rare opportunity to work on places and
relocations within the city, and linkage with two other databases will make it possible to follow
people from birth to death.
Building such a database by hand would take at least 50,000 hours of work. But, thanks to the
recent developments in deep learning and machine learning, it is now possible to build huge
databases with automated reading systems including handwriting recognition and natural
language understanding. Indeed, because of these recent advances, optical printed named entity
recognition (OP-NER) is now performing very well. On the other hand, while handwriting
recognition by machine has become a reality, also thanks to deep learning, optical handwritten
named entity recognition (OH-NER) has not received much attention. OH-NER is expected to
achieve promising results on handwritten marriage certificates dating from 1880 to 1923. This
project research questions will focus on the best strategies for word disambiguation for
handwritten named entity recognition. We will explore end-to-end deep learning architectures for
OH-NER, writer adaptation of the recognition system, and named entity disambiguation by
exploiting the French mortality database (INSEE) and the French POPP database. An additional
benefit of this study is that a unique and very large dataset of handwritten material for named
entity recognition will be built.Laboratoire LITIS, EA 4108, Université de Rouen, 76 800 Saint-Etienne du Rouvray, FRANCE

The research engineer will be in charge of the development of a processing pipeline dedicated
to optical printed named entity recognition (OP-NER).
He will closely collaborate with a Ph.D.
student in charge of Handwritten Named Entity Recognition (OH-NER).
OP-NER is the project’s easiest task and will benefit from the latest results achieved by the LITIS
team on similar problems on financial yearbooks. Images are first processed to extract every text
information. This will be achieved with the DAN architecture designed by LITIS which is a deep-
learning-based OCR (https://arxiv.org/abs/2203.12273). The research engineer will be in charge of
this OCR task. A benchmark of DAN against available OCR software such as Tesseract and EasyOCR
will also be conducted. Then the textual transcriptions will be processed for named entity
extraction and recognition. Named entity recognition is a well-defined task in the natural language
processing community. In the EXO-POPP context however, we need to define each entity to be
extracted more precisely to make a clear distinction between the different people occurring in the
text. For example, we need to distinguish between wife and husband names, and similarly for the
parents of the husband and of the wife, and so on for the witnesses, children, etc. An estimation
of around 135 categories has been established. The TAG definition was made by LITIS as well as a
first training dataset. Manually tagging the transcriptions has been made possible through the
PIVAN web-based collaborative interface (https://litis-exopopp.univ-rouen.fr/collection/12 ). This
platform provides in one single web interface a document image viewer, viewing and editing of
OCR results and text tagging facilities for NER. PIVAN eases the annotation efforts of the H&SS
trainees and allows for building the large, annotated datasets required for machine learning
algorithms to run optimally. The research engineer will oversee datasets generation and curation
as per the requirement of the EXO-POPP NER task, including the handwritten datasets.
The named entity recognition task will be based on a state-of-the-art machine learning approach.
We have started some experimentations with the well-known FLAIR NER library
(https://github.com/flairNLP/flair). We plan to continue developing and tuning the EXO-POPP
named entity recognition module using this library. The research engineer will oversee this task
