Textual information processed by an application may be used to access data from one or more on-line data source (e.g., Wikipedia) which may be used to enhance the user experience or to improve user productivity from using the application. One such application may be a search service that accesses such data based on input data provided to the application. For example, the application may parse instant messages sent and received by a user to extract keywords, phrases or links, which are then used to retrieve information from a repository of data obtained form various data sources. In this manner, data related to the subject matters of the user's communication may be readily accessed by the user, if desired, in a convenient manner To deliver real time performance, the repository of data may be pre-processed (e.g., indexed) to facilitate information retrieval.
