CIRCLE 2020 | Joint Conference of the Information Retrieval Communities in Europe
July 6-9, 2020, Samatan, Gers, France

Call for Contributions

CIRCLE 2020 arose from a twofold wish to gather three national Information Retrieval (IR) conferences and to offer young researchers the opportunity to meet and discuss with senior researchers.

CIRCLE is supported by the ARIA French conference (CORIA, COnférence en Recherche d’Information et Applications), the Spanish Conference on Information Retrieval (CERI, Congreso Español de Recuperación de Información), the Italian Information Retrieval Workshop, and the Swiss IR community.

The main objective of CIRCLE 2020 is to propose a unique place for stimulating and disseminating research in IR, where senior/industrial and early stage researchers (including MSc and PhD students) can network and discuss their research results in a friendly environment. CIRCLE 2020 will take place on July 6-9, 2020 at Samatan, Gers, south of France (50 minutes from Toulouse). More information at

Participation in CIRCLE 2020 will be low fare charged.

• 10 February 2020: Intention of submission (title and short abstract)
• 28 February 2020: Deadline for long paper submission
• 20 March 2020: Deadline for short papers and demos submissions
• 30 April 2020: Long paper, short paper, and demos notifications
• 29 May 2020: Deadline for camera-ready papers

CIRCLE 2020 offers an opportunity to present and discuss both theoretical and empirical research. Relevant topics include, but are not restricted to:
. Search and ranking
. Content analysis, recommendation and classification
. Domain-specific applications
. Artificial intelligence, semantics and dialog
. Human factors and interfaces
. Evaluation
. Future directions

For the common track, submissions must be in English and in PDF using the current ACM two-column conference format. The conference language for this track will be English. Submission will be peer reviewed by at least 3 reviewers in a double blind process by the CIRCLE common program committee. Submission will be through Easychair at The proceedings will be sent to for online publication. Papers may range from theoretical work, experimental research, to system and project descriptions.

Authors are invited to submit one of the following types of contributions:
. Long original papers (up to 8 pages + 1 page for references)
. Short original papers (up to 4 pages + 1 page for references)
. Extended abstracts containing descriptions of ongoing projects or presenting already published results (up to 2 pages)

While long papers (max. 8 pages plus up to 1 page for references) describe mature and original research results, short papers (max. 4 pages plus up to 1 page for references) typically discuss exciting new work that is not yet mature enough for a long paper, such as for example doctoral papers. In particular, novel but significant proposals will be considered for acceptance into this category despite not having gone through sufficient experimental validation or lacking strong theoretical foundation. Extended abstracts (max. 2 pages) may include a system demonstration, a project presentation, an already published piece of work (e.g. in a top level IR journal or conference). Applications of information retrieval to novel areas are especially welcome. Intention of submission (title and short abstract) will be used for reviewers to bid on papers. Each accepted paper will be included in the conference proceedings and orally presented.

There will be also CERI submissions: the Spanish Conference on Information Retrieval will organize sessions with oral presentations in Spanish for certain papers written in either Spanish or English. Special interest will be devoted to papers on applications with municipal, regional or national impact in Spain, collaborations from Spanish institutions and companies, or using corpuses in Spanish. Short original papers or extended abstracts are allowed. 
Note: as in previous editions of CERI (details will be given by the Spanish IR association defended thesis from June 2018 to May 2020 could qualify for the SERI Award to the best Spanish PhD dissertation in IR.
