This disclosure provides examples of computer-implemented systems and processes for determining a user browsing session context, intent, or activity based on contextual information associated with a user's browsing session, and using this determined context as a basis to filter or improve selection of content items for the user. For example, if the user is building up a watch list (for example, discovering new titles), then it may be desirable to filter out items for recommendation which are already on that watch list. However, when the user is searching for something to watch in the current session (for example, consuming content), then it may be more appropriate to show items already added to the watch list as recommended content. Item recommendations can thus be improved or filtered based in part on parameters of the user's browsing activity with respect to content items.

Adaptive filtering to adjust automated selection of content using weightings based on contextual parameters of a browsing session

This disclosure describes systems and associated methods that can selectively filter seed behavior, e.g., user activity used to generate item recommendations. In some embodiments, seed behaviors and catalog items are associated with categories in an electronic catalog, and a particular seed behavior is used to generate user recommendations if it is more recent than a user's last purchase in the category of the seed behavior. For example, a user's activity in the TV category, e.g., viewing various TV models, may not be used to generate recommendations if the activity occurred prior to the user's purchase of a TV. As a result, in certain embodiments, additional TVs may not appear in the user's recommendations following her purchase, reflecting that the user has fulfilled her desire to purchase a TV.
