Recommendation Solutions

Context-aware recommender systems (CARS) can be built to adapt the list of item recommendations to different context situations (e.g., time, location, companion, budget, weather, etc.). Users can receive the appropriate recommendations tailored by their preferences in specific contexts.

The DeepCARSKit Library

The DeepCARSKit library is an open-source and deep learning based context-aware recommendation library, where it can be used, modified and distributed under the terms of the MIT License. CARSKit was built upon Recbole v1.0.0 with an environment of Python v3.7+, PyTorch v1.7+. It is specifically designed for context-aware recommendations. It implements context-aware recommendation models based on neural networks. The major components in DeepCARSKit can be viewed as follows.
