International Classification:

C02N031/10

US Classification:

436 37, 422 80, 422 83, 422129, 422130, 436159, 436172, 436174, 436180

Abstract:

The present invention discloses an apparatus and method for rapid analysis of members of a combinatorial library. The apparatus includes a plurality of vessels for containing individual library members and a fluid handling system that apportions a test fluid about equally between each of the vessels. This allows for simultaneous screening of library members by detecting changes in test fluid following contact with individual library members. Fluid flow through each of the vessels is controlled using passive flow restrictors or active flow controllers to ensure that each library member contacts approximately the same amount of test fluid per unit time. The disclosed apparatus is especially useful for screening library members based on their ability to catalyze the conversion of fluid reactants.

International Classification:

G06Q 30/00

US Classification:

705 26

Abstract:

A method and apparatus for generating search results with higher relevancy. The present invention exploits the fact that users' choices on each given search term tend to converge to several products from several merchants, and all of the results are very relevant to the search term. In one embodiment, these results are used to decide the order of merchants for each search term. By learning the users' choices, especially from purchasing and/or clicking information, highly relevant and most popular products can be assigned a higher score or rank over text relevant only products.

US Classification:

707 3, 707 10, 709203

Abstract:

A method and apparatus for generating search results with higher relevancy. More specifically, the present invention provides a determination whether a search term belongs to a particular category. Namely, properly associating a search term with the correct category will greatly enhance the generation of search results with higher relevancy.

Abstract:

A method and apparatus for generating search results with higher relevancy. More specifically, the present invention provides a listing of narrowing or related search terms based upon the search term submitted by the user. The present invention effectively guides users to narrow their search by guiding users to select or click on highly related search terms. In one embodiment, the listing of the highly related search terms is generated in accordance with sales and/or click information, e. g. , via scoring of search terms that is premised on sales and/or click information.

International Classification:

G10L 15/00

US Classification:

704 2, 704 8, 707 4

Abstract:

A translation on demand (“TOD”), in one embodiment, receives a search request with a search term from a user in a native language across the Internet. The search term is translated into at least one foreign language using automatic translation software (“ATS”) according to specifications listed with the search request. After the search term is translated, a search with the search term in both native and foreign languages is performed. Once receipt of the outcome of the search, search results are displayed, wherein each entry or document of the search results also includes a brief description presented in the native language. The TOD system also generates multiple TOD price selections. The TOD price selections allow a user to place an order to translate a selected document. A translation job order for translating the selected document is then distributed for bidding over the network.

International Classification:

US Classification:

707706

Abstract:

A method and apparatus is provided for hosting within a search engine, large-scale heterogeneous repositories of searchable and navigable content. Customers of the hosting platform are customers wanting to outsource the management of their searchable content. Content domain experts from each customer independently define a taxonomy of categories and attributes for their structured content that form a hierarchical set of nodes (a directed graph) that are mapped to a common physical search engine infrastructure. The mapping algorithm that maps unique attributes across potentially very different subject domains onto the same physical infrastructure is introduced. Once the physical structure is created, the search engine can use it for searching or navigating just within one customer's domain or users can search across multiple customer domains. When a customer makes changes to the logical structure, each individual change is categorized as compatible and incompatible, and executed in different time frames based on the amount of disruption it will require to the operational system.
