Abstract: Systems and methods of generating and using a bitmap index are disclosed. The bitmap index stores bit strings. In a particular implementation, each bit string in the bitmap index corresponds to an attribute of an audience. Each location in each bit string corresponds to the same audience member. The bitmap index supports parallelized and distributed execution of queries with respect to data indexed by the bitmap index. For example, the described bitmap index can be used to index advertising data, healthcare data, financial data, etc.

Abstract: A method includes receiving, at a computing device comprising a processor, a request to determine bicliques in a graph, where the graph includes a first set of nodes, a second set of nodes, and a set of edges, each edge in the set of edges connecting a node in the first set of nodes to a node in the second set of nodes. The method also includes determining at least one biclique based on querying a bitmap index representing the graph, where the bitmap index includes a plurality of bit strings corresponding to the first set of nodes, and where a value stored in a particular location in each bit string indicates whether an edge connects a first node corresponding to the bit string to a second node corresponding to the particular location.

Abstract: A method includes receiving a query directed to a bitmap index. The bitmap index includes a plurality of bit strings, where a value stored in a particular location in each of the bit strings indicates whether a corresponding signal associated with a signal source has been received, and where the bitmap index includes at least a first metadata value associated with each of the bit strings, at least a second metadata value associated with each of a plurality of signal sources, or both. The method also includes generating a query execution plan for the query and generating query results based on the query execution plan. The query results identify at least one signal associated with at least one bit string of the plurality of bit strings, at least one signal source of the plurality of signal sources, and at least one of the first metadata value or the second metadata value.

Abstract: A particular method includes receiving, at a computing device including a processor, a first event signal that includes a first browser identifier and first information indicative of a first interaction with respect to a media property. The method also includes determining that the first browser identifier corresponds to a particular user and associating the first event signal with a user profile of the particular user. The method further includes receiving a second event signal that includes a second browser identifier that is different from the first browser identifier and second information indicative of a second interaction with respect to the media property. The method includes determining that the second browser identifier corresponds to the particular user and associating the second event signal with the user profile.
