Abstract
The Joint Conference of the Information Retrieval Communities in Europe (CIRCLE 2020) is the second
joint conference of the French, Italian, and Spanish information retrieval communities. The three days of
conference gathered interesting studies and re- search work on a wide range of topics on information
retrieval, such as topic and document modeling, web search, information retrieval in e-government,
social media, recommender systems, information retrieval evaluation, indexation and annotation, user
profiling and interaction, frameworks and systems, and semantic extraction.
It was hosted by Université de Toulouse, France in a holiday resort at Samatan and took place from
the 4th to the 7th of July 20221

1. Introduction
The Joint Conference of the Information Retrieval Communities in Europe (CIRCLE 2022,
https://www.irit.fr/CIRCLE) is the second joint conference of the French, Italian, and Spanish
information retrieval communities.
The second edition of CIRCLE taked place on July 2022 at Samatan, Gers, south of France (50
minutes from Toulouse). CIRCLE 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, COn-
férence 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 is to propose a
unique place for stimulating and disseminating research in IR, where senior/industrial and early

results in a friendly environment.
2. Conference Topics
CIRCLE 2022 includes both theoretical and experimental papers on core IR and papers on
connections between IR and close disciplines including but not limited to natural language
understanding and information extraction. Relevant topics include, but are not restricted to:
Search and ranking: Research on core IR algorithmic topics, including IR at scale, covering
topics such as:
• Queries and query analysis.
• Web search, including link analysis, sponsored search, search advertising, adversarial
search and spam, and vertical search.
• Retrieval models and ranking, including diversity and aggregated search.
• Efficiency and scalability.

• Efficient text representations, indexing and ranking.
Future directions: Research with theoretical or empirical contributions on new technical or
social aspects of IR, especially in more speculative directions or with emerging technolo-
gies, covering topics such as:

• Ethics, economics, and politics.
• Applications of search to social good.
• IR with new devices, including wearable computing, neuroinformatics, sensors,
Internet-of-Things, vehicles.
3. Submissions
For the CIRCLE common track, submissions were requested to be in English, the social language
of the conference. Submission were peer reviewed by at least two members of the conference
program committee in a double blind process. Authors were invited to submit one of the
following types of contributions:
• Long original papers (from 6 to 9 pages including references) describing mature and
original research results
• Short original papers (from 3 to 5 pages including references) which 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.
• Resource and demo papers (from 3 to 7 pages including references). A resource paper
describes IR test collections software tools made available to the IR research community.
Demo papers showcasing new technologies and prototypes in the cope of CIRCLE
• Extended abstracts (up to 3 pages including references) containing descriptions of ongoing
projects or presenting already published results
The Easychair system (https://easychair.org) was used for the paper submission and review
processes. The accepted papers ranged from theoretical work and experimental research to
system and project descriptions. Each accepted paper was included in the conference proceed-
ings and was orally presented. The proceedings are online published by CEUR Work- shop
Proceedings at https://www.irit.fr/CIRCLE/CIRCCLE2022Proceedings.pdf, as well as through
the editor’s web site.

5. Publications
In total, 13 long papers, 6 short papers, 2 demo papers and 15 extended abstracts were accepted
for publication and presentation, leading to 32 oral communications. These papers were grouped
into thematic sessions as follows (see https://www.irit.fr/CIRCLE/program/):
• Text classification
• Legal Domain and Social Media Analysis
• Recommendation and Search
• Medical information access
• Automatic Labelling and Relation Extraction
• My work in 120 seconds
• Poster and demo session
In addition, two invited speakers opened the two days of the conference:
• Géraldine Damnati, Orange Innovation, Lannion, France. Her talk was entitled "From
opinion mining to document search: an overview of applicative use-cases along with
practical implementation issues and open research questions". She presented several
applicative use-cases developed at Orange Innovation to feed operational services towards
customers and employees. She discussed the current bottlenecks for the deployment of
state-of-the art models in operational services. She presented how tasks that are studied
in research can yield new opportunities and, conversely, how feedbacks from operational
projects can yield new research directions.
• Evangelos Kanoulas, University of Amsterdam, The Netherlands. His talk was entitled "In-
formation Retrieval Is Going Conversational". Evangelos discussed how conversing with
the users has risen as a natural means to face complexity in search and recommendation.
He also reviewed some of the recent progress in conversational information retrieval and
focused on open issues such as evaluation and new abilities a search engine has to be
armed with.
6. Local Organization
Josiane Mothe, CIRCLE general chair warmly thanks the other local organizers without whom
the conference could not have happened:
• Max Chevalier, Université de Toulouse, UT3
• Alexandre Clausse, Université de Toulouse, UT3
• Fabienne Denuc, Université de Toulouse, UT2J
• Irène Figuerolas, Université de Toulouse, UT2J
• José Moreno, Université de Toulouse, UT3
• Nathalie Neptune, Université de Toulouse, UT2J
• Ludovic Tanguy, Université de Toulouse, UT2J
• Md Zia Ullah, Université de Toulouse, UT3
The conference was co-organised by the Université de Toulouse (UT2J, Toulouse, France) and
Universidad Nacional de Education a Distancia (UNED, Madrid, Spain). The conference was
hosted by Université de Toulouse Jean-Jaurès and took place in the country side nearby Toulouse
(Samatan, Gers) in an holiday resort. This choice was driven by the willing of providing a
friendly environment where young researchers and students could meet and discuss without
any barriers with senior researchers. COVID pandemia and remote attendance are not fertilizers
for networking, specifically for early career researchers and CIRCLE had the aim to contribute
to integrating young and early career researchers into the information retrieval community.
7. Sponsor and Student Grant
CIRCLE had many sponsors that the organizers would like to thank warmly. At the Diamond
level, UNED, Madrid helped CIRCLE specially for hiring conference rooms, coffee break, social
events, wifi connexion and travels and accommodation costs for UNED co-organizers. At
the Platinum ACM SIGIR contributed to welcome all the students at a very low rate of 250 €,
including the conference attendance, the accommodation, all the meals and social events. Also
at a platenium level, the Région Occitanie contributed to travels expanses (2€ to connect the
resort center from Toulouse) as well as social events. At the gold level, Université Jean Jaurès
(Toulouse) contributed with the accounting and secretariat as well as for general expenses. At the
silver level, both Université Paul Sabatier (Toulouse) and Institut de Recherche en Informatique
de Toulouse (UMR 5505 CNRS) contributed to invited speakers expanses and free registration
or low fees for students. Springer offered five books on Information Retrieval and Machine
Learning topics that were given as prices on social activities to students.
