Abstract: Systems and methods are presented for performing natural language processing and reasoning. In some embodiments, a computer-implemented methods is presented. The method may include accessing a natural language query from a user, parsing the natural language query into a computer-interpretable semantic representation, converting the semantic representation into a computer-interpretable logical syntax, determining a solution to the computer-interpretable logical syntax using a reasoning engine and at least one data source, and outputting an answer to the natural language query using the solution to the computer-interpretable logical syntax.

Abstract: A writing instrument that provides a magnification lens to view a logo or visual image from inside the barrel of the pen. The writing instrument has a cartridge, printable sleeve, magnification member and a pen barrel. The pen barrel is capable of accepting the printable sleeve and cartridge therethrough. The pen barrel has a first end and a second end. On the surface of the pen barrel between the first and second ends there is a magnification member. The magnification member is capable of magnifying the visual image on the printable sleeve. The printable sleeve is movable between successive positions to successively display one or more visual images with respect to the magnification member. The magnification member can be a clear or tinted lens for magnifying visual images such as a logo or message.

Abstract: A writing instrument having a retractable writing tip and hollow pliable seal with a closure pinched by a metal spring clip to seal the instrument's writing tip from contact with open air. The instrument may use writing tips, such as roller ball, fountain and felt tips, which employ volatile inks.
