Abstract:
A server system may include at least one non-transitory, processor-readable storage medium and at least one processor in communication with the at least one storage medium. The at least one storage medium may include at least one set of instructions for generating a value added in-stream contents (VAC) database for ad display. The at least one processor may be configured to execute the at least one set of instructions to receive an candidate article for display in a stream on a website; determine a sentiment of the candidate article towards a first subject matter associated with the article; classify the candidate article to a first type category based on the sentiment when the sentiment has a positive effect to a commercial success of a second subject matter; and generating a VAC database based on the first type category.
