Recommender systems

Abstract

Recommender systems assist and augment a natural social process. In a typical recommender system people, provide recommendations as inputs, which tile system then aggregates and directs to appropriate recipients. In some cases, the primary transformation is in the aggregation; in others, the system's value lies in its ability to make good matches between recommenders and those seeking recommendations. This special section includes descriptions of five recommender systems. A sixth article analyzes incentives for provision of recommendations. Recommender systems introduce two interesting incentive problems. First, once one has established a profile of interests, it is easy to free ride by consuming evaluations provided by others. Second, if anyone can provide recommendations, content owners may generate mountains of positive recommendations for their own materials and negative recommendations for their competitors. Recommender systems also raise concerns about personal privacy.

  • Based on some kind of input, recommender systems select a set of items from a large pool of available items and recommend a list of information links for users to choose.

    “Based on some kind of input, recommender systems select a set of items from a large pool of available items and recommend a list of information links for users to choose (Resnick & Varian, 1997).”

    The Recommender Systems section says systems take recommendations as inputs, aggregate them, and direct them to recipients; it also describes recommending interesting items. But it does not characterize recommender systems generally as selecting from a large pool and presenting users with a list of information links. It describes links as one possible type of recommendation alongside books, movies, and other items. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
