摘要：A computer converts a question received in a natural language format into a

string of text elements. The computer searches a corpus comprising unstructuredpassages with the string of the text elements as search terms to identify a selection ofunstructured passages from the corpus relevant to the text elements. The computerannotates the selection of relevant unstructured passages with one or more annotationsaccording to at least one natural language annotation type to generate an annotatedselection knowledge base. The computer modifies the string of text elements byannotating at least one of the text elements according to the at least one naturallanguage annotation type. The computer searches the annotated selection knowledgebase using the modified string of text elements to generate a selection of rankedpassages. The computer identifies an answer to the question based on the selection ofranked passages.
