Abstract: Mechanisms are provided in a question answering (QA) system comprising a QA system pipeline that analyzes an input question and generates an answer to the input question, for pre-processing the input question. The mechanisms receive an input question and input the input question to a pre-processor flow path having one or more pre-processors. The one or more pre-processors transform the input question into a transformed question by correcting errors in a formulation of the input question that are determined to be detrimental to efficient and accurate processing of the input question by a QA system pipeline of the QA system. The transformed question is then input to the QA system pipeline of the QA system which processes the transformed question to generate and output an answer to the input question.

Abstract: Embodiments of the present invention address deficiencies of the art in respect to tab control presentation and provide a method, system and computer program product for tab control management with type-ahead and thumbnail imagery. In an embodiment of the invention, a tab control navigation method can be provided. The method can include arranging thumbnail images for corresponding tabs in a tab control within a tab navigation view, and, in response to a selection of one of the thumbnail images, activating a corresponding one of the tabs in the tab control. The method further can include receiving text in a type-ahead filter, and filtering the tab navigation view to include only thumbnail images corresponding to tabs associated with the text.
