RARe: Raising Ad Revenue Framework with Context-Aware Reranking

Modern recommender systems excel at optimizing search result relevance for e-commerce platforms. While maintaining this relevance, platforms seek opportunities to maximize revenue through search result adjustments. To address the trade-off between relevance and revenue, we propose the RARe (Raising Advertisement Revenue) framework. RARe stacks a click model and a reranking model. We train the RARe framework with a loss function to find revenue and relevance trade-offs. According to our experience, the click model is crucial in the RARe framework. We propose and compare two different click models that take into account the context of items in a search result. The first click model is a Gradient-Boosting Decision Tree with Concatenation (GBDT-C), which includes a context in the traditional GBDT model for click prediction. The second model, SAINT-Q, adapts the Sequential Attention model to capture influences between search results. Our experiments indicate that the proposed click models outperform baselines and improve the overall quality of our framework. Experiments on the industrial dataset, which will be released publicly, show RARe’s significant revenue improvements while preserving a high relevance.
