ICFHR 2020: Call for Competitions

Web page: http://icfhr2020.org/competitions
Contact: competitions@icfhr2020.org

PDF Version of this Call: CallForCompetition_ICFHR2020_v1.pdf

Important Dates

Dec 13, 2019  Submission of competition proposals
Dec 20, 2019  Notification of acceptance
Dec 24, 2019  Competitions open to participants
Jun 14, 2020  Submission of competition paper
Jun 26, 2020  Notification of acceptance

The ICFHR 2020 Organizing Committee invites proposals for competitions addressing current research challenges in handwriting recognition and related areas of pattern recognition and vision. Competitions should aim at evaluating the performance of individual methods and systems that fall within the context of the conference’s call for papers. Competitions should also participate in the sharing and standardization of handwriting recognition processes.

Proposals must contain the following information:

  1. A brief description of the competition, including which is the particular task under evaluation and why this competition could be of interest to the ICFHR community. If a similar competition has been held in a previous edition of ICFHR, the novel additions of the proposed one must be clearly explained.
  2. A draft of the outline of the competition describing which data is planned to be used, how will the submitted methods be evaluated and which performance measures will be used. Proposals should state explicitly whether data and annotations are already available or otherwise the timeframe to prepare them.
  3. How datasets and evaluation scripts will be made publicly available.
  4. The list of rules or best practices which will be imposed to participants (allowing multiple submissions or not, allowing external data or not, public ranking or not, etc.). Each competition relies on the academic integrity of the competitors.
  5. The names, contact information, and brief CVs of the competition organizers, outlining previous experience in performance evaluation and/or organizing competitions.

Submissions

Proposals should be submitted by electronic mail to the ICFHR2020 Competitions Chairs:
Harold Mouchère and Dimosthenis Karatzas (competitions@icfhr2020.org)

Rules

The following rules will apply to the accepted competitions:

  • All competitions must run well in advance of the conference.
  • Datasets used in the competitions must be made available through the TC10/TC11 Online Resources website after the end of the competitions (or equivalent arrangement by approval of the competition chairs).
  • Evaluation methodologies and metrics used must be described in detail so that results can be replicated later.
  • The name of the competition must be standardized by starting with “ICFHR2020” e.g. “ICFHR2020 Competition on …”;
  • Reports (full papers) on each competition will be reviewed and, if accepted (the competition run according to plan and is appropriately described), will be published in the ICFHR2020 conference proceedings.
  • The results of accepted competitions will be announced during a dedicated session of the conference. Competition organizers are expected to participate to this dedicated session during ICFHR 2020. Participants should be encouraged to present their algorithms (if not already done) in a conference paper at ICFHR 2020.
  • Participants should be encouraged to share their algorithms and code using one of the open-source licenses
  • Competitions must have sufficient number of participants (about 5, depending of the originality of the topic) to be able to draw meaningful conclusions.
  • Each competition will be allocated some time in parallel to the poster session, during which they can run a mini-workshop (e.g. presenting results and conclusions, inviting winning methods to present their methods, lessons learnt, etc).
  • Each competition accepted to present results in the conference, should prepare a poster presentation and present it during ICFHR 2020.

PhD Subject: use of graph attention networks for named entity extraction in scanned documents

Contact: Abdel Belaïd, LORIA lab, READ group, Nancy, France, abdel.belaid@loria.fr

Motivations

Since the entry into force of the RGPD (General Regulation on Data Protection) on May 25, 2018, European citizens have the legal basis necessary to control and reclaim their personal data. It is a question of providing the technical means that are simple and accessible to as many people as possible to administer their data, to share it, while allowing the organizations that use it to comply with the legislation in force. For this, we want to use massively artificial intelligence to provide a disruptive approach to the management of user data and especially their documents. It is a question of proposing a totally automatic management of the documents of the users, as well at the level of the classification as of the exploitation of the information which they contain. This information (metadata) will then be integrated into an ontology of personal data in order to interrogate these data in a structured way but above all to propose automated reasoning algorithms.

Subject

A first solution has been proposed for the extraction of named entities in personal documents of the “Invoice” type. Documents are scanned, and named entities are extracted from images after Optical Character Recognition (OCR) reading. These entities correspond to the information relating to the issuing company, the delivery and billing addresses, the products ordered as well as the different prices and totals. A deep learning technique based on convolutional network graphs (GCN) has been implemented for the extraction of these entities [4]. It consists in taking advantage of the contextual links in the neighborhoods of the words of the document. Each node of the graph represents a word of the document and its relations connect it to its four closest neighbors in the four cardinal directions. For the purposes of convolution, the graph in Euclidean space is replaced by the adjacency matrix describing the words in the spectral domain. Thus, the model learns to individually label the words of the document based on their neighborhood links. In this project, the READ team seeks to extend the extraction method to other types of documents in order to test its ability to extract named entities of different types and in different types of media. We want to test and compare graph attention networks (GAN) of [4, 5, 6, 7, 8] and see which is best suited to the problem. The aim is to better specialize neighborhood graphs to better represent semi-structured information, by retaining the nodes around the headers or information indicators, because it will be tedious to use all the words in the document. This was the case for invoices that are very structured, which is not the case for all documents.

Framework

The implementation will be done in Python using the Keras API based on the Tensorflow library.
