Abstract: A method and analytics tools for locating experts with specific sets of expertise are disclosed, the method including providing a collection of documents P0; generating categories representing fields of expertise derived from the collection of documents P0; refining the taxonomy of the categories by applying user domain knowledge; extracting structured fields from the collection of documents P0; constructing a contingency table having a first axis defined by the extracted structured fields and a second axis defined by the categories; and using the contingency table to identify a set of experts having a related expertise. The method may also include a network graph analysis that aids visualization of the relationship between people and expertise.

Abstract: A method is disclosed for conducting a query to transform data in a pre-existing database, the method comprising: collecting database information from the pre-existing database, the database information including inconsistent dimensional tables and fact tables; running an entity discovery process on the inconsistent dimensional tables and the fact tables to produce entity mapping tables; using the entity mapping tables to resolve the inconsistent dimensional tables into resolved dimensional tables; and running the query on a resolved database to obtain a query result, the resolved database including the resolved dimensional table.

Abstract: A system, method, and computer program product enabling individual user devices to authenticate and validate a digital message sent by a distribution center, without requiring transmissions to the distribution center. The center transmits the message with an appended modulus that is the product of two specially selected primes. The transmission also includes an appended authentication value that is based on an original message hash value, a new message hash value, and the modulus. The new message hash value is designed to be the center's public RSA key; a corresponding private RSA key is also computed. Individual user devices combine a digital signet, a public modulus, preferably unique hardware-based numbers, and an original message hash to compute a unique integrity value K. Subsequent messages are similarly processed to determine new integrity values K?, which equal K if and only if new messages originated from the center and have not been corrupted.

Abstract: Methods, systems, and computer program products are provided for the online convex optimization problem, in which the decision maker has knowledge of the all past states and resulting cost functions for his previous choices and attempts to make a new choice that results in minimum regret. The method does not rely upon the structure of the cost function or the characterization of the states and takes advantage of the similarity between successive states to enable the method to converge to a reasonably optimal result.

Abstract: A magnetic data track used in a magnetic shift register memory system may be fabricated by forming a multilayered stack of alternating dielectric and/or silicon layers. A trench is etched in the multi-layer stack structure. A selective etching process is used to corrugate the walls of trench. A seed layer is applied to the walls and bottom of the trench; the seed layer is covered with a magnetic layer. The trench is filled with an insulating material. A patterned layer is applied and portions of insulating material exposed by the pattern are removed, forming holes. Magnetic material and seed layer exposed in holes is selectively removed. The holes are filled with insulating material and connecting leads are attached to data tracks.
