Embodiments of the invention relate to identification of material that contains linguistically related content. Key phrases are filtered through a content store to ascertain the linguistically related content and to move the identified content to a target corpus. At least two iterations of the filtering process are employed. Each subsequent iteration of the filtering process identifies at least one new key phrase within the filtered material. In addition, each subsequent iteration takes place with a union of each previously employed key phrase and each new key phrase. As new content is identified, the content is populated to the target corpus.

(canceled) 15. The system of claim 14, wherein the second set of related documents populated to the target corpus is linguistically related to documents previously added to the target corpus. 16. The system of claim 13, wherein the automatic expansion further comprises an iterative expansion of the target corpus for linguistically related documents. 17. The system of claim 16, further comprising the extraction manager to limit the expansion of documents being added to the target corpus to new content within the second subset. 18. The system of claim 16, further comprising the extraction manager to identify a threshold associated with the criteria and wherein conclude the automatic expansion includes the criteria to meet the threshold. 19. A computer program product for automatically identifying linguistically related material within a computing environment, the computer program product comprising: a computer readable storage medium readable by a processing unit and having stored instructions for execution by the processing unit for performing a method comprising: initializing a target corpus; identifying initial key phrases from a domain corpus related to the target corpus wherein each initial key phrase comprises string, the identification is based on a statistical analysis of the domain corpus; extracting the identified initial key phrases; and storing the extracted initial key phrases in a master list at a first memory location; ranking the master list; identifying a target corpus criteria; employing an application to automatically expand the target corpus, the automatic expansion including: selectively populating the target corpus with one or more documents from a source corpus based on the ranking and a first linguistic relationship between each key phrase in the master list and the one or more documents; and identifying one or more new key phrases from the selectively populated target corpus; assigning a first value to the identified one or more new key phrases based on a second linguistic relationship to the target corpus; and adding the identified new key phrases to the master list, and applying a union of the new key phrases to extract a second set of related documents for populating to the selectively populated target corpus; learning from the selective population comprising: identifying one or more secondary documents present in the filtered list and absent from the target corpus; identifying one or more secondary key phrases associated with the secondary documents; assigning a second value to the identified secondary key phrases based on a third linguistic relationship to the target domain; and updating the master list for subsequent iterations, wherein the master list update discounts the second value assigned to at least one secondary key phrase; and concluding the automatic expansion when the identified target corpus criteria meets a threshold. 20.
