13. The system of claim 7 , wherein the key word is a first key word, the key word base language semantic vector is a first key word base language semantic vector, the set of distance data is a first set of distance data, and the computer-executable instructions further cause the at least one processor to: determine a second key word base language semantic vector based on a second key word; and determine a second set of distance data including a third distance between the first base language semantic vector and the second key word base language semantic vector, and a fourth distance between the second base language semantic vector and the second key word base language semantic vector, the determining of the score of the electronic content including determining the score based at least in part on the second set of distance data.
7. A system, comprising: at least one memory that stores computer-executable instructions; and at least one processor to access the at least one memory, the computer-executable instructions, when executed, to cause the at least one processor to at least: in response to receiving electronic content to be delivered to a destination address, determine a first base language semantic vector corresponding to a first word in the electronic content; determine a second base language semantic vector corresponding to a second word in the electronic content; determine, for a key word, a key word base language semantic vector, the key word being a taboo word; determine a set of distance data including a first distance between the key word base language semantic vector and the first base language semantic vector, and a second distance between the key word base language semantic vector and the second base language semantic vector; determine whether the first distance and the second distance are less than a threshold distance; when the first and second distances are less than the threshold distance, add the first distance and the second distance to obtain a sum; determine a score of the electronic content based at least in part on the sum, wherein the score indicates a relevance of the electronic content to the key word; and determine that the electronic content is not to be delivered to the destination address based at least in part on the score of the electronic content; and prevent the electronic content from being delivered to the destination address.
