Abstract: A computer implemented method detects suspicious domains. A computer system determines a homographic similarity between a target domain and a known domain. The compute system compares first registration information for the target domain and second registration information for the known domain to form a registration comparison in response the homographic similarity being sufficiently similar to be potentially suspicious. The computer system compares a set of first landing page images for the target domain and a set of second landing page images for the known domain to form an image comparison in response to a match between the first ownership information for the target domain and the second ownership information for the known domain being absent. The computer system determines a threat level for the target domain based on the image comparison.

Abstract: A method, computer system, and a computer program product for semantic matching is provided. The present invention may include pre-processing and normalizing a job title. The present invention may include deconstructing the job title based on at least one semantic element. The present invention may include training a machine learning model. The present invention may include creating a contextual word representation of the job title using the at least one semantic element of the job title. The present invention may include computing a similarity score for each of the at least one semantic element of the job title. The present invention may lastly include applying a weight to the computed similarity score before making a final match assessment.
