The number of themes of a document is determined from the number of clusters of the document. The specificity of the document is determined from the number of themes. ## Claims ### Claim 1 A method comprising: accessing a record stored in one or more tangible media, the record recording a plurality of clusters of a plurality of documents, a document comprising a plurality of words, a cluster comprising a plurality of satisfactorily affine words of the plurality of words, a cluster indicating a theme; establishing a number of themes of each document of at least a subset of the plurality of documents; determining a specificity of the each document according to the number of themes by: determining that the each document is more specific if the each document has a lower number of themes; and determining that the each document is less specific if the each document has a higher number of themes; receiving a search query comprising a document specificity request, the document specificity indicated using a slider; and retrieving one or more documents of the plurality of documents that satisfy the search query and the document specificity request. ### Claim 2 (depends on 1) The method of claim 1, the establishing the number of themes of the each document of at least the subset of the plurality of documents further comprising: determining a number of clusters of the each document; and calculating the number of themes of the each document from the number of clusters. ### Claim 3 (depends on 1) The method of claim 1, the establishing the number of themes of the each document of at least the subset of the plurality of documents further comprising: identifying a depth with respect to which the number of themes is to be established; and establishing the number of themes with respect to the identified depth. ### Claim 4 (depends on 1) The method of claim 1, the establishing the number of themes of the each document of at least the subset of the plurality of documents further comprising: selecting a plurality of keywords from the each document; identifying one or more candidate themes related to the keywords; and if the one or more candidate themes match the document, establishing the one or more candidate themes as the themes of the document. ### Claim 5 (depends on 1) The method of claim 1, further comprising performing a specificity analysis by: facilitating a graphical display of the specificity for the each document of the plurality of documents, the graphical display comprising an element selected from a set consisting of a graphical indicator, a graphical modification, and a graph. ### Claim 6 (depends on 1) The method of claim 1, further comprising: sorting the one or more retrieved documents according to the specificities of the documents of the set of documents. ### Claim 7 (depends on 1) The method of claim 1: the plurality of documents associated with one or more users; and the determining the specificity of the each document according to the number of themes further comprising determining a user specificity of the one or more users from the plurality of documents. ### Claim 8 (depends on 1) The method of claim 1: the plurality of documents associated with one or more users; the determining the specificity of the each document according to the number of themes further comprising determining a user specificity of the one or more users from the plurality of documents; and further comprising selecting one or more documents for the one or more users according to the user specificity. ### Claim 9 (depends on 1) The method of claim 1: the plurality of documents associated with one or more users; the determining the specificity of the each document according to the number of themes further comprising determining a user specificity of the one or more users from the plurality of documents; and further comprising monitoring the user specificity of the one or more users. ### Claim 10 (depends on 1) The method of claim 1: the plurality of documents associated with a corpus; and the determining the specificity of the each document according to the number of themes further comprising determining a corpus specificity of the corpus from the plurality of documents. ### Claim 11 One or more non-transitory computer-readable tangible media encoding software operable when executed to: access a record stored in one or more tangible media, the record recording a plurality of clusters of a plurality of documents, a document comprising a plurality of words, a cluster comprising a plurality of satisfactorily affine words of the plurality of words, a cluster indicating a theme; establish a number of themes of each document of at least a subset of the plurality of documents; determine a specificity of the each document according to the number of themes by: determining that the each document is more specific if the each document has a lower number of themes; and determining that the each document is less specific if the each document has a higher number of themes; receive a search query comprising a document specificity request, the document specificity indicated using a slider; and retrieve one or more documents of the plurality of documents that satisfy the search query and the document specificity request. ### Claim 12 (depends on 11) The computer-readable tangible media of claim 11, further operable to establish the number of themes of the each document of at least the subset of the plurality of documents by: determining a number of clusters of the each document; and calculating the number of themes of the each document from the number of clusters. ### Claim 13 (depends on 11) The computer-readable tangible media of claim 11, further operable to establish the number of themes of the each document of at least the subset of the plurality of documents by: identifying a depth with respect to which the number of themes is to be established; and establishing the number of themes with respect to the identified depth. ### Claim 14 (depends on 11) The computer-readable tangible media of claim 11, further operable to establish the number of themes of the each document of at least the subset of the plurality of documents by: selecting a plurality of keywords from the each document; identifying one or more candidate themes related to the keywords; and if the one or more candidate themes match the document, establishing the one or more candidate themes as the themes of the document. ### Claim 15 (depends on 11) The computer-readable tangible media of claim 11, further operable to perform a specificity analysis by: facilitating a graphical display of the specificity for the each document of the plurality of documents, the graphical display comprising an element selected from a set consisting of a graphical indicator, a graphical modification, and a graph. ### Claim 16 (depends on 11) The computer-readable tangible media of claim 11, further operable to: sorting the one or more retrieved documents according to the specificities of the documents of the set of documents. ### Claim 17 (depends on 11) The computer-readable tangible media of claim 11: the plurality of documents associated with one or more users; and the computer-readable tangible media further operable to determine the specificity of the each document according to the number of themes by determining a user specificity of the one or more users from the plurality of documents. ### Claim 18 (depends on 11) The computer-readable tangible media of claim 11: the plurality of documents associated with one or more users; and the computer-readable tangible media further operable to: determine the specificity of the each document according to the number of themes by determining a user specificity of the one or more users from the plurality of documents; and select one or more documents for the one or more users according to the user specificity. ### Claim 19 (depends on 11) The computer-readable tangible media of claim 11: the plurality of documents associated with one or more users; the computer-readable tangible media further operable to: determine the specificity of the each document according to the number of themes by determining a user specificity of the one or more users from the plurality of documents; and monitor the user specificity of the one or more users. ### Claim 20 (depends on 11) The computer-readable tangible media of claim 11: the plurality of documents associated with a corpus; and the computer-readable tangible media further operable to: determine the specificity of the each document according to the number of themes by determining a corpus specificity of the corpus from the plurality of documents.
