Graphing else matters: exploiting aspect opinions and ratings in explainable graph-based recommendations [article]

Iván Cantador, Andrés Carvallo, Fernando Diez, Denis Parra
2022 arXiv   pre-print
Different from previous work, in this paper, we propose to exploit embeddings extracted from graphs that combine information from ratings and aspect-based opinions expressed in textual reviews.  ...  In particular, current recommendation methods based on graph embeddings have shown state-of-the-art performance. These methods commonly encode latent rating patterns and content features.  ...  Graph-based recommendations We can distinguish between three main types of approaches that use graphs for recommendation purposes: path-based, embedding-based, and unified.  ...
