A system and a method for providing a context-based AD(ADvertisement) service, and a recording medium storing a program thereof are provided to offer AD about online contents by selecting the AD with context tendency suitable for the online contents. An unused word database(135) and a context/token score database(137) respectively store unused words, and context patterns and token scores. A token generator(110) receives the online contents and outputs a contracted token. A context pattern analyzer(130) processes and outputs the token received from the token generator to an AD selector. An AD detector(150) outputs the AD and pattern information of the AD by comparing the token stored in the token database with the contracted token. The AD selector selects the highest pattern among the context patterns received from the AD detector by comparing the patterns received from the AD detector with each context pattern score received from the context analyzer. |
