Abstract: A system and methods for evaluating whether a public review matches another review is disclosed. The method includes obtaining a private review and a public review of a business. A likelihood the public review matches the private review is evaluated. The evaluation includes evaluating a match distance between text bodies, reviewer names, review dates and ratings in the public review and the private review. Evaluation rules are applied to determine the likelihood of a match.

Abstract: A system and methods for correcting domain names in invalid email addresses are described herein. The method includes receiving email failure information including a bad domain name. The bad domain name is compared to valid domain names in a valid domain name database and a match distance of the bad domain name to valid domain names in the valid domain name database is evaluated. Confidence scores for the valid domain names are prepared based on the match distance. Valid domain names having confidence scores exceeding a domain match threshold are identified. A valid domain name with a confidence score exceeding the domain match threshold is selected. The method involves heuristics and machine learning. System administrator intervention may be received to assist in the selecting. An email note is sent to the corrected domain name.

Abstract: A water torque converter for extracting energy from the reciprocal motion of water beneath waves in a body of water comprising an open frame on which is mounted a rigid sail. The rigid sail is guidingly moved from one end of the frame to the opposite end of the frame by the reciprocal motion of the water. An elongated driving member is connected through a multi-clutch mechanism to the sail. This elongated driving member is also connected to an output shaft. The reciprocal movement of the sail results in the output shaft to be rotationally driven in one direction.
