Call for Papers

Important note: Due to concerns about COVID-19, RecSys 2020 will be a fully virtual conference. ORSUM will coordinate closely with RecSys organizers to ensure a suitable format and calendar for authors and participants.

Modern online web-based systems continuously generate data at very fast rates. This continuous flow of data encompasses web content - e.g. posts, news, products, comments -, but also user feedback - such as ratings, views, reads, clicks, thumbs up -, as well as context information - user device, geographic info, social network, current user activity, weather. This is potentially overwhelming for systems and algorithms design to train in offline batches, given the continuous and potentially fast change of content, context and user preferences. Therefore it is important to investigate online methods to be able to transparently adapt to the inherent dynamics of online systems. Incremental models that learn from data streams are gaining attention in the recommender systems community, given their natural ability to deal with data generated in dynamic, complex environments. User modeling and personalization can particularly benefit from algorithms capable of maintaining models incrementally and online, as data is generated.

The objective of this workshop is to foster contributions and bring together a growing community of researchers and practitioners interested in online, adaptive approaches to user modeling, recommendation and personalization, as well as other related tasks, such as evaluation, reproducibility, privacy and explainability.

Relevant topics include, but are not limited to:

Submission instructions

We welcome original, unpublished work in the form of either long or short paper submissions via EasyChair at: https://easychair.org/conferences/?conf=orsum2020. Long papers must not exceed 16 pages (excluding references), and should report research at a mature stage. We also welcome the submission of preliminary results of ongoing research in the form of short papers with a maximum length of 8 pages, (excluding references). Papers must be formatted in LaTeX and follow the workshop template (available soon).

The review process is double-blind, so authors are required to remove any content that allows author identification.
