1. A method comprising: categorizing, by a processor, a first set of attributes associated with a first list of objects, wherein each of the objects represents a video asset that is associated with one or more of the attributes of the first set; ranking, by the processor, the first set of attributes according to a criterion associated with one or more characteristics of the attributes, wherein the criterion specifies a frequency of occurrence of an attribute of the first set of attributes; presenting the first list of objects and associated attributes; receiving a first input indicating selection of at least one of the attributes of the first set; collapsing the first list of objects into a second list of objects consisting of a subset of the first list of objects, wherein the subset consists of the objects associated with the selected attributes; generating, by the processor, a second set of attributes based on the second list of objects, the second set of attributes comprising a non-selected attribute of the first set of attributes, wherein each of the attributes of the second set of attributes is associated with at least one object of the second list of objects; ranking, by the processor, the second set of attributes according to the criterion, wherein the criterion specifies a frequency of occurrence of an attribute of the second set of attributes; presenting the second list of objects and associated attributes in response to the first input; receiving a second input indicating selection of one of the objects in the second list; and retrieving the video asset corresponding to the one selected object, wherein the selection of the at least one of the attributes of the first set of attributes specifies a maximum and/or minimum value.
