  • Publication number: 20080256059
    Abstract: A system is described for generating query suggestions using a network of users and advertisers. The system may include a memory, an interface, and a processor. The memory may store a data representing a network comprising query items linked to advertisement items via link items, wherein each link item comprises a weight representing the strength of the relationship between each query item and advertisement item, a search query item, and a relevance value for each query item. The processor may be operatively connected to the memory and the interface and may identify the data representing the network and receive a search query item. The processor may calculate a relevance value for each additional query item in the network based on its relationship to the received search query item. The processor may then suggest the query items with the highest relevance values to the user via the interface.
