Abstract: Systems and methods for classifying job skills based on a job skill taxonomy built using artificial intelligence are described. The method may include identifying a set of job skill terms from a corpus of job description documents, generating a synonym file by associating each of the job skill terms with a canonical job skill, extracting a set of job skills from the corpus of job description documents using the synonym file, generating job skill relationship information based on the extracted set of job skills, and creating a job skill taxonomy based on the job skill relationship information, wherein the job skill taxonomy comprises a hierarchy of job skills.
