Guided word association based domain name detection

A computer-implemented method comprising:

• obtaining an original domain name;
• constructing a feature space from a corpus of text, wherein each word appearing in the corpus is represented as a vector in the feature space;
• detecting whether a domain name registration exists for each combination of the original domain name and each of a plurality of seed words from the feature space;
• determining, for each seed word included in an existing domain name registration, a plurality of nearest neighbor candidate words, based on vector distance in the feature space;
• and
• repeating, for at least one repetition, the detecting and the determining, wherein the plurality of nearest neighbor candidate words are utilized as the plurality of seed words.

An apparatus comprising:

• an obtaining section configured to obtain an original domain name;
• a constructing section configured to construct a feature space from a corpus of text, wherein each word appearing in the corpus is represented as a vector in the feature space;
• a detecting section configured to detect whether a domain name registration exists for each combination of the original domain name and each of a plurality of seed words from the feature space;
• a determining section configured to determine, for each seed word included in an existing domain name registration, a plurality of nearest neighbor candidate words, based on vector distance in the feature space;
• and
• a repeating section configured to cause the detecting section and the determining section to repeat, for at least one repetition, their respective functions utilizing the plurality of nearest neighbor candidate words as the plurality of seed words
• wherein the obtaining, constructing, detecting, determining, and repeating sections are implemented by a memory device for storing program code and a hardware processor for executing the program code.
