A framework for a question and answering (Q&A) system defines a mapping of recognized semantics of user questions, to a well structured query model that can be executed on arbitrary data warehouses. Embodiments may utilize a plugin-based architecture, with various elements responsible for: extracting information from a user's question, formulating and executing a structured query, and post-processing a result by rendering a chart. Plugins within a certain processing step may be executed independently of one another, imparting a significant degree of parallelism. The framework may build on top of natural language processing technologies, and in particular embodiments may be based upon established standards (e.g. RDF and SparQL) thereby allowing adaptation to a variety of domains and use cases.
