Summary

IntentTune is a novel framework designed to resolve ambiguous or under-specified query intents within e-commerce search systems. Many real-world queries, such as "watch" or "shirt," lack explicit attributes like gender or age group, posing a significant challenge for accurate intent detection. IntentTune addresses this by leveraging either user-specific behavioral signals, including search history, browsing activity, and profile attributes, or population-level demand patterns. Experiments on real-world e-commerce data demonstrate that population-level patterns alone are insufficient for reliable intent inference. Instead, user-specific behavioral signals, particularly prior search queries, significantly outperform both population statistics and static profile information for inferring gender, age group, product category, and size intent from underspecified queries.

Key takeaway

For e-commerce search engineers aiming to improve relevance for ambiguous user queries, you should prioritize integrating user-specific behavioral signals. Your systems will achieve more accurate intent detection by leveraging prior search queries and browsing activity over static user profiles or broad population trends. Focus on building models that dynamically adapt to individual user context to resolve under-specified intents like gender, age group, product category, and size.

Key insights

Resolving ambiguous e-commerce queries requires personalized behavioral signals, not just population-level demand data.

Principles

• Population-level demand is insufficient for ambiguous query intent.
• User-specific behavioral signals are superior for intent inference.
• Prior search queries are particularly effective signals.

Method

IntentTune leverages user-specific behavioral signals (search history, browsing, profile) or population-level demand patterns to infer latent user intent from under-specified e-commerce queries.

In practice

• Infer gender from underspecified queries.
• Determine age group from search history.
• Identify product category and size intent.
