  • providing access to a set of content items, each of the content items having associated metadata stored in an electronically readable medium that describes the corresponding content item;

    receiving at the processor a first input from a user, the first input including linguistic elements intended by the user to identify at least one desired content item;

    associating by the processor at least one linguistic element of the first input with a first conversation session;

    providing by the processor a first response based on the first input and based on the metadata associated with the content items;

    receiving at the processor a second input from the user;

    inferring by the processor whether or not the second input from the user is related to the at least one linguistic element associated with the first conversation session;

    upon a condition in which the second input is inferred to relate to the at least one linguistic element associated with the first conversation session, providing by the processor a second response based on the metadata associated with the content items, the second input, and the at least one linguistic element of the first input associated with the first conversation session; and

    upon a condition in which the second input is inferred to not relate to the at least one linguistic element associated with the first conversation session, providing by the processor a second response based on the metadata associated with the content items and the second input.
