An approach is provided in which a knowledge manager creates a pattern set based on training data that includes paraphrases and a set of first syntactic patterns. The knowledge manager receives a user question and matches one of the first syntactic patterns to a second syntactic pattern generated from the user question. Based on the matching, the knowledge manager generates new questions using the paraphrases in the pattern set and utilizes the new questions to query a second set of data and generate candidate answers that correspond to the user question.

Information retrieval using structured resources for paraphrase resolution

An approach is provided in which a knowledge manager creates a pattern set that includes paraphrases and corresponding paraphrase scores. The paraphrase scores are based on a set of first candidate answers obtained from querying a first set of resource data. The knowledge manager performs a search, which is based on the paraphrases and a user question, on a second set of resource data and identifies a set of second candidate answers. In turn, the knowledge manager scores the set of second candidate answers based on the paraphrase scores corresponding to the paraphrases utilized to identify the set of second candidate answers.

Answer scoring by using structured resources to generate paraphrases

An approach is provided in which a number of sections from a sequence of characters included in a Portable Document Format (PDF) file are identified. Each of the identified sections includes a unique set of coordinate positions. The approach builds links between the sections based on a relative position of each of the sections in relation to the other sections along an axis. The approach repeatedly merges sections based on the links that were built to form increasingly larger sections until a final larger section is generated with the characters appearing in a manner consistent with human reading of the rendered PDF document rather than the placement of the characters found within the original PDF file.
