RECURSIVE AGGLOMERATIVE CLUSTERING OF TIME-STRUCTURED COMMUNICATIONS

1 . A method of document cluster labeling, the method comprising:

selecting, by a processing device, a current document cluster of a plurality of document clusters;

initializing a label associated with the current document cluster;

selecting a term from a list of terms comprised by the document cluster;

appending the term to the label associated with the current document cluster;

responsive to determining that the label is found in a label dictionary, iteratively selecting a next term from the list of terms comprised by the document cluster and appending the next term to the label associated with the current document cluster;

responsive to failing to locate the label in the label dictionary, inserting the label into the label dictionary; and

associating the label with the current document cluster.

2 . The method of claim 1 , further comprising:

sorting the plurality of document clusters by a number of documents comprised by a respective document cluster.

3 . The method of claim 1 , further comprising:

sorting the list of terms by a respective term weight.

4 . The method of claim 1 , further comprising:

excluding, from the list of terms, a term comprising at least part of an entity name.

5 . The method of claim 1 , further comprising:

visually representing, via a graphical user interface, one or more clusters of the plurality of document clusters in a visual association with respective labels.

6 . The method of claim 1 , wherein the plurality of document clusters comprise a plurality of electronic mail messages.

7 . The method of claim 1 , wherein the plurality of document clusters comprise a plurality of documents represented by respective vectors in a hyperspace of document features.

8 . A system, comprising:

a memory; and

a processor coupled to the memory, wherein the processor is configured to:

select a current document cluster of a plurality of document clusters;

initialize a label associated with the current document cluster;

select a term from a list of terms comprised by the document cluster;

append the term to the label associated with the current document cluster;

responsive to determining that the label is found in a label dictionary, iteratively select a next term from the list of terms comprised by the document cluster and appending the next term to the label associated with the current document cluster;

responsive to failing to locate the label in the label dictionary, insert the label into the label dictionary; and

associate the label with the current document cluster.

9 . The system of claim 8 , wherein the processor is further configured to:

sort the plurality of document clusters by a number of documents comprised by a respective document cluster.

10 . The system of claim 8 , wherein the processor is further configured to:

sort the list of terms by a respective term weight.

11 . The system of claim 8 , wherein the processor is further configured to:

exclude, from the list of terms, a term comprising at least part of an entity name.

12 . The system of claim 8 , wherein the processor is further configured to:

visually represent, via a graphical user interface, one or more clusters of the plurality of document clusters in a visual association with respective labels.

13 . The system of claim 8 , wherein the plurality of document clusters comprise a plurality of electronic mail messages.

14 . The system of claim 8 , wherein the plurality of document clusters comprise a plurality of documents represented by respective vectors in a hyperspace of document features.

15 . A non-transitory computer-readable storage medium comprising executable instructions that, when executed by a computer system, cause the computer system to:

select a current document cluster of a plurality of document clusters;

initialize a label associated with the current document cluster;

select a term from a list of terms comprised by the document cluster;

append the term to the label associated with the current document cluster;

responsive to determining that the label is found in a label dictionary, iteratively select a next term from the list of terms comprised by the document cluster and appending the next term to the label associated with the current document cluster;

responsive to failing to locate the label in the label dictionary, insert the label into the label dictionary; and

associate the label with the current document cluster.

16 . The non-transitory computer-readable storage medium of claim 15 , further comprising executable instructions that, when executed by the computer system, cause the computer system to:

sort the plurality of document clusters by a number of documents comprised by a respective document cluster.

17 . The non-transitory computer-readable storage medium of claim 15 , further comprising executable instructions that, when executed by the computer system, cause the computer system to:

sort the list of terms by a respective term weight.

18 . The non-transitory computer-readable storage medium of claim 15 , further comprising executable instructions that, when executed by the computer system, cause the computer system to:

exclude, from the list of terms, a term comprising at least part of an entity name.

19 . The non-transitory computer-readable storage medium of claim 15 , further comprising executable instructions that, when executed by the computer system, cause the computer system to:

visually represent, via a graphical user interface, one or more clusters of the plurality of document clusters in a visual association with respective labels.

20 . The non-transitory computer-readable storage medium of claim 15 , wherein the plurality of document clusters comprise a plurality of electronic mail messages.
