What is the difference between contextual relevance and topical relevance?

When discussing the difference between contextual relevance and topical relevance, it's essential to understand that contextual relevance pertains specifically to the user's current situation and needs. This concept focuses on how well the content aligns with the user's intent, circumstances, and the context in which they are searching. For instance, if a user is looking for information on "best restaurants" while in a specific city, the results that provide nearby dining options would be considered contextually relevant.

On the other hand, topical relevance generally refers to how well content matches the broader subject matter or topic of the search query, rather than the specific circumstances of the user at that moment. While topical relevance may consider overall content quality, it does not account for situational factors that can significantly influence what is relevant to a user at a particular time.

This distinction makes it clear that contextual relevance is about understanding the nuances of a user's situation, while topical relevance is focused on the adequacy of the subject matter itself in relation to a query.
