Abstract
A method for determining topic relevance of an email thread with an electronic device is described. The method includes removing redundancy from email messages in an email thread, grouping a number of email threads into a number of email clusters, identifying high information gain terms for each email cluster, identifying topic terms for each email cluster from the high information gain terms and determining a relevance of the number of email threads in an email cluster based on the topic terms for the email cluster and a threshold number of email messages in an email thread.
Claims15
A method for determining topic relevance of an email thread with an electronic device, comprising:
- removing redundancy from email messages in an email thread;
- grouping a number of email threads into a number of email clusters;
- identifying high information gain terms for each email cluster;
- identifying topic terms for each email duster from the high information gain terms;
- and
- determining a relevance of the number of email threads in an email cluster based on the topic terms for the email cluster and a threshold number of email messages in an email thread.
A system for determining topic relevance of an email thread, comprising:
- a de-duplicate engine to de-duplicate quoted text from email messages in an email thread;
- a cluster engine to cluster a number of email threads into email clusters;
- a terms engine to identify a number of topic terms for each of the email clusters;
- and
- a relevancy engine to determine a relevance of the number of email threads in the email clusters based on the number of topic terms and a threshold number of email messages in each email thread.
A computer program product for determining topic relevance of an email thread, the computer program product comprising:
- a computer readable storage medium comprising computer usable program code embodied therewith, the computer usable program code comprising computer usable program code to, when executed by a processor, to:
- remove quotations of a first number of email messages from a second number of email messages in an email thread;
- cluster a number of email threads into a number of email clusters;
- determine a number of high information gain terms in an email cluster;
- determine a number of topic terms from the high information gain terms;
- and
- determine the relevancy of a number of email threads within each email cluster based on the topic terms.
