Abstract: An online system provides content based on context of host content. The online system allows content providers to define specific context for providing their content for display to users, including specifying categories, format, popularity, and visual appearance of host content eligible for hosting their content. To determine which content a specific content item is eligible for hosting, the online system categories host content items according to specific criteria defined by different content providers for hosting various content. Each content is indexed by classification groups into which the host content items are classified. If a particular content item includes an opportunity for presenting content, the online system identifies content which the particular content item is eligible for hosting. The online system selects one or more identified content for presentation via the opportunity.

Abstract: In one embodiment, a method includes accessing a first feature vector representing a video-content object corresponding to a node in a social graph, wherein the video-content object comprises frames and audio and is associated with text, the first feature vector is based on one or more of the frames; accessing a second feature vector representing the video-content object, wherein the second feature vector is based on at least some of the text; accessing a third feature vector representing the video-content object, wherein the third feature vector is based on one or more portions of the audio; determining a fourth feature vector representing the video-content object, wherein the fourth feature vector is based on a combination of the first, second, and third feature vectors; and determining a context of the video-content object based on the fourth feature vector and social-graph information.

Abstract: In one embodiment, a method includes accessing a video-content object, determining a first feature vector representing the video-content object using a first recognition module of a first type based on an object in the video-content object, and determining a second feature vector representing the video-content object using a second recognition module of a second type based on the first feature vector. The first type is different from the second type. The method also includes determining a context of the video-content object based on the second feature vector.
