39. The computing device of claim 32 , wherein the list of queries is identified based on a predefined set of queries.
32. A computing device configured as an information-processing system for determining the likelihood that a source document is a duplicate of another document in a document corpus, the computing device comprising: a processor; and a memory; wherein the computing device is communicatively coupled to a document corpus and further communicatively coupled to a display device, and is configured to, in response to obtaining a source document for inclusion in the document corpus: execute a plurality of search queries on the document corpus, wherein the execution of each search query yields a corresponding results set identifying a set of documents in the document corpus ordered according to the relevance of each document to the executed query; for each document identified in each results set, generate a document score according to the breadth of the query and the position of the identified document in the ordered results set in which the identified document is found; select a subset of the identified documents of the results sets, wherein the generated scores for the documents of the selected subset are higher than a threshold score, and wherein selecting the subset of the identified documents of the results sets further comprises determining a minimum score for a potential duplicate document from the document corpus that is returned in more than one results set, and including the potential duplicate document in the subset of the identified documents of the results sets in a case where the minimum score is higher than the threshold score; and present the subset of the identified documents of the results sets to the display device for display to a user for evaluation as to whether the source document is a duplicate of another document in the document corpus.
