Abstract: Systems, methods, and computer-readable storage media are provided for generating a taxonomic view from a standard taxonomy and generating audience segments for targeting using a formal grammar. A manually-tagged subset of categories of the standard taxonomy is provided to a server. Each category in the subset of categories is tagged based on an entity's own legacy taxonomy. A taxonomy slicer is applied to the subset of manually-tagged categories to determine parent/child relationships for each category in the subset, and to assemble the categories into the taxonomic view. The taxonomic view maintains interoperability with the standard taxonomy, and with other entities using views of the standard taxonomy. Further, a formal grammar is defined for specifying online behaviors for targeting, and is applied to extracted categories of the standard taxonomy and/or taxonomic view. The formal grammar may be programmatically applied during behavioral targeting.

Abstract: Performing an operation is disclosed. A first keyword is received. For the first keyword an associated semantic group of one or more keywords associated by a semantic relationship is identified. An electronic advertising operation is performed using a second keyword associated with the identified semantic group.

Abstract: An information extraction system that allows users to ask questions about documents in a database, and responds to queries by returning possibly relevant information which is extracted from the documents. The system is domain-independent, and automatically builds its own subject knowledge base. It can be applied to any new corpus of text with quick results, and no requirement for lengthy manual input. For this reason, it is also a dynamic system which can acquire new knowledge and add it to the knowledge base immediately by automatically identifying new names, events, or concepts.
