Network security database filtering tool

A method comprising:

• creating a word vector from a message, wherein:
• the word vector comprises an entry for each word of the message;
• each entry indicating a number of occurrences in the message of the word for that entry;
• and
• the word vector associates each word of the message with a weight;
• calculating cosine difference between the word vector and each group vector of a plurality of group vectors, wherein each group vector is associated with a network security issue;
• assigning the word vector to a group for a group vector of the plurality of group vectors based on the calculated cosine difference between the word vector and the group vector for the group, wherein the group indicates a subtype of network security issue associated with the group vector;
• identifying one or more words in the word vector associated with a weight greater than a weight threshold value;
• extracting the one or more words associated with a weight greater than the weight threshold value;
• creating a second message using the extracted one or more words;
• assigning the second message to the group assigned to the word vector;
• and
• sending a notification to a user associated with the message in response to assigning the word vector to the group.

A computer program comprising executable instructions stored in a non-transitory computer-readable storage medium that when executed by a processor causes the processor to:

• create a word vector from a message, wherein:
• the word vector comprises an entry for each word of the message;
• each entry indicating a number of occurrences in the message of the word for that entry;
• and
• the word vector associates each word of the message with a weight;
• calculate a cosine difference between the word vector and each group vector of a plurality of the group vectors, wherein each group vector is associated with a network security issue;
• assign the word vector to a group for a group vector of the plurality of group vectors based on the calculated cosine difference between the word vector and the group vector for the group, wherein the group indicates a subtype of network security issue associated with the group vector;
• identify one or more words in the word vector associated with a weight greater than a weight threshold value;
• extract the one or more words associated with a weight greater than the weight threshold value;
• create a second message using the extracted one or more words;
• assign the second message to the group assigned to the word vector;
• and
• send a notification to a user associated with the message in response to assigning the word vector to the group.
