Abstract: Methods and systems are provided for managing knowledge. Users of the knowledge management (KM) service or system may provide post questions, provide answers or search for answers via a user interface. For a given question, users may collectively construct and refine an answer hierarchy that may include multiple answer paths or solutions to the same question. To this end, users may add, remove and/or modify nodes of the answer hierarchy. The nodes may be of predefined types such as Step, Goto or Fork. In addition, users may provide or modify content specific to individual nodes of the answer hierarchy such as attachments, questions, references or comments. Given an answer hierarchy, users may preview alternate paths and compare different answer paths representing different solutions based on user-specific fact patterns or requirements before making their selections along a particular path to a solution.

To this end, users may add, remove and/or modify nodes of the answer hierarchy. The nodes may be of predefined types such as Step, Fork, and Goto. In addition, users may interact with a particular node and provide or modify content specific to individual nodes of the answer hierarchy such as attachments, questions, comments, or references. Given an answer hierarchy, users may select different answer paths or solutions comprising a subset of nodes in the answer hierarchy, for example, based on user-specific fact patterns or requirements.
