The limitations of learning offline from observed data are widely recognized, however, applying debiasing strategies like Inverse Propensity Weighting does not always solve the problem of making wrong estimates. This concept paper contributes a summary of debiasing strategies in recommender systems and the design of several toy examples demonstrating the limits of these commonly applied approaches. Therefore, we propose to map the causality frameworks of potential outcomes and structural causal models onto the recommender systems domain in order to foster future research and development. For instance, applying causal discovery strategies on offline data to learn the causal graph in order to compute counterfactuals or improve debiasing strategies.<\/jats:p>","DOI":"10.1145\/3629169","type":"journal-article","created":{"date-parts":[[2023,10,26]],"date-time":"2023-10-26T21:44:54Z","timestamp":1698356694000},"page":"1-34","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Towards a Causal Decision-Making Framework for Recommender Systems"],"prefix":"10.1145","volume":"2","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0235-0421","authenticated-orcid":false,"given":"Emanuele","family":"Cavenaghi","sequence":"first","affiliation":[{"name":"Free University of Bozen-Bolzano, Bolzano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4423-2121","authenticated-orcid":false,"given":"Alessio","family":"Zanga","sequence":"additional","affiliation":[{"name":"University of Milano-Bicocca, Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1394-0507","authenticated-orcid":false,"given":"Fabio","family":"Stella","sequence":"additional","affiliation":[{"name":"University of Milano-Bicocca, Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4805-5516","authenticated-orcid":false,"given":"Markus","family":"Zanker","sequence":"additional","affiliation":[{"name":"Free University of Bozen-Bolzano, Bolzano, Italy, University of Klagenfurt, Klagenfurt Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2024,5,14]]},"reference":[{"key":"e_1_3_1_2_2","series-title":"RecSys\u201917","doi-asserted-by":"crossref","first-page":"42","DOI":"10.1145\/3109859.3109912","volume-title":"Proceedings of the Eleventh ACM Conference on Recommender Systems","author":"Abdollahpouri Himan","year":"2017","unstructured":"Himan Abdollahpouri, Robin Burke, and Bamshad Mobasher. 2017.
