A system and method to facilitate importation of data taxonomies within a network are described. Advertiser entities access a data storage module within a network-based entity to retrieve content information from one or more content taxonomies stored within the data storage module. Subsequently, the advertiser entities select advertisements targeted to specific users based on the retrieved content information and further transmit the advertisements to the network-based entity. Furthermore, publisher entities and/or advertiser entities transmit data, such as, for example, associated taxonomy information, to the network-based entity. The entity receives the respective taxonomy information and parses the taxonomy information to extract node information and associated categories related to the received information. Finally, the entity integrates the node information and associated categories into one or more taxonomies stored within the data storage module. Alternatively, the entity maps the node information and associated categories into corresponding nodes within one or more taxonomies stored within the data storage module, and further stores the mapping information into a mapping database within the data storage module.
