A recommendation process includes the consideration of the compatibility of the items being recommended. An electronic processing system for generating a compatibility-aware recommendation output set to a is user based, at least in part, on a set of item compatibility rules. The system includes a processing system of one or more processors configured to receive applicable data, including i) user preference data, and ii) item compatibility rules, and to produce a compatibility-aware recommendation output set using the user preference data and the item compatibility rules. A method and computer-readable storage device containing the method are also presented.

System, method, and article of manufacture for making a compatibility-aware recommendations to a user

The invention includes an electronic processing system, a method and a computer readable storage device for generating a serendipity-weighted recommendation output set to a user based, at least in part, on a serendipity function. The system includes a processing system to receive user item preference data and community item popularity data. The processing system is also configured to produce an item recommendation set from the user item preference data, produce a set of item serendipity control values in response to the serendipity function and the community item popularity data, and combine the item recommendation set with the set of item serendipity control values to produce a serendipity-weighted and filtered recommendation output set. The method includes receiving item preference data and community item popularity data. The method further includes producing an item recommendation set from the user item preference data, using the processing system, and generating a set of item serendipity control values in response to the community item popularity data and a serendipity function, also using the processing system. The method also includes combining the item recommendation set and the set of item serendipity control values to produce a serendipity-weighted and filtered item recommendation output set, using the processing system. The computer readable storage device, has a set of program instructions physically embodied thereon, executable by a computer, to perform a method similar to that just described.

The method includes receiving applicable data by the processing system, including inputting item recommendation data and community item popularity data. The method further includes generating a set of item serendipity control values in response to the community item popularity data and a serendipity function, using the processing system, and combining the item recommendation data and the set of item serendipity control values to produce a serendipity-weighted and filtered item recommendation output set, also using the processing system. The invention also includes a computer readable medium having a having a set of program instructions physically embodied thereon, executable by a computer, to perform a method similar to the method described above.

System, method and article of manufacture for increasing the user value of recommendations

A disposable tubular pneumotachometer in which the air-resistive material covering over the air outlet is a fabric with multiple sub-miniature tubular apertures to provide capillary air flow and, in the preferred form, has a uniformly diverging air outlet formed by air outlet openings through the wall of the pneumotachometer tube and an imperforate proportionally tapered air-diverging surface facing the air outlet openings.
