13. A computer program product for compressing domain-related data, the computer program product comprising: one or more computer-readable tangible storage devices; program instructions, stored on at least one of the one or more storage devices, to retrieve data pertaining to a subject matter domain, forming the domain-related data; program instructions, stored on at least one of the one or more storage devices, to receive, forming a set of seeds, a set of text strings, wherein a text string forms a seed, and wherein the seed is derived from a domain topology; program instructions, stored on at least one of the one or more storage devices, to receive a description of a linguistic structure present in a language of the domain-related data; program instructions, stored on at least one of the one or more storage devices, to receive a statistical model applicable to the domain-related data; program instructions, stored on at least one of the one or more storage devices, to extract, using a processor and a memory, a set of portions of the domain-related data, a portion in the set of portions forming a nugget, and the set of portions forming a set of nuggets, wherein a nugget matches the statistical model according to a criterion, and wherein the nugget conforms to the linguistic structure within a threshold degree; program instructions, stored on at least one of the one or more storage devices, to score a nugget in the set of nuggets according to a subset of a set of features found in the nuggets; program instructions, stored on at least one of the one or more storage devices, to select a subset of nuggets, the subset including the scored nugget, wherein a score of each nugget included in the subset of nuggets exceeds a score threshold; program instructions, stored on at least one of the one or more storage devices, to combine the subset of nuggets to form a pseudo-document; and program instructions, stored on at least one of the one or more storage devices, to submit the pseudo-document to an application for answering a question related to the domain.
19. The computer program product of claim 13 , wherein the statistical model provides a frequency of a lexical redundancy of a portion of the domain-related data.
