Call For Papers

International Workshop on eXPErt RecommendaTion for Community Question Answering (XPERT4CQA)
Workshop website:

in conjunction with

with 23rd IEEE International Conference on Data Mining (IEEE ICDM 2023,

December 1-4, 2023
Shanghai, China

[(TBD) Due to the ongoing COVID-19 circumstances around the world, ICDM 2023 will be a hybird conference. Changes to a fully on-site or a fully virtual event will be evaluated considering the pandemic situation]

Community question answering is a fundamental knowledge sharing service, with a strong impact on society. Essentially, the askers of a community post questions and rely upon the wisdom and collective intelligence of the repliers in that community, for their questions to be timely and effectively answered. Unfortunately, because of the growing number of both unanswered and newly-posted questions, repliers cannot timely answer, while askers do not necessarily receive satisfactory answers even after a long time. Expert recommendation is the process aimed to the timely sharing of high-quality knowledge from answerers to askers, which allows for routing questions to the most trustworthy expert repliers. This workshop proposal aims to provide a premier international forum on all aspects of interest to expert recommendation for community question answering. In particular, the workshop will
- bring together practitioners and researchers from academia and industry, to discuss challenges, practices, principles and preliminary results, share ideas, develop innovative models, methods, techniques and tools;
- provide a venue, where participants form an interdisciplinary research community, promoting scientific cooperation and exchanges within and across areas, for unprecedented synergistic insights and approaches;
- advance research, through a focused analysis of open issues, emerging trends, unexplored directions and novel solutions.

Scope and Topics of Interest
Because of an increasing interest in academia and industry, expert recommendation for community question answering has grown into an active area of multidisciplinary research, with a vast body of contributions at the crossroads of Recommender Systems, Information Retrieval, Data Mining, Machine Learning, Data Science, Knowledge Representation, Knowledge Management, Social Computing and Natural Language Processing. The workshop will solicit contributions reporting original and unpublished results regarding theoretical developments, principled models, methods, techniques and algorithms, experimental results, empirical evaluations of state-of-the-art approaches, evaluation metrics, experiences with new systems and related challenges, new data sets and respective analytics, application-oriented studies, promising preliminary ideas, work in progress, demonstrations and tools. All submissions will be reviewed, by rigorously accounting for their appropriateness and relevance to the workshop as well as the novelty, importance, technical soundness and clarity of their contributions.

The topics of interest for the workshop include, but are not limited to, the following:

1. Topical interest, topical expertise, authority, centrality, relevance, social roles, trustworthiness, confidence.
2. (Advanced) Modeling of Users, Roles and Behaviors
3. Question routing/Expert finding
4. Exploitation of External non-CQA Data
5. Dynamicity
6. Answerer Motivation
7. Exposure to Questions
8. Recommendation of Newcomers and Lurkers
9. Recommendation of Expert Answerers using Knowledge Graphs
10. Recommendation of Expert Answerers for Context-dependent Questions
11. Recommendation of Collaborative Groups of Expert Answerers
