Patent number: 11972424Abstract: Systems and techniques are generally described for detecting evasive terms in item listings. In some examples, a list of keywords associated with a first category of specified items may be received. In some examples, text data associated with a first item may be received. A first plurality of tokens representing a corrected version of the text data may be generated using spell correction techniques. In some cases, first flag data indicating that the text data constitutes evasive text may be generated based at least in part on the generation of the first plurality of tokens. The first flag data and a numerical representation of the first plurality of tokens may be input into a binary classifier trained to generate label data indicating whether text data associated with a given item is evasive or non-evasive. The binary classifier may generate label data indicating that the text data associated with the first item is evasive.Type: GrantFiled: August 31, 2021Date of Patent: April 30, 2024Assignee: Amazon Technologies, Inc.Inventors: Igor Grudetskyi, Masafumi Yamaguchi, Yi Ren

Patent number: 5997382Abstract: In a method of processing a sealing surface of a casting to eliminate casting defects on or in the vicinity of the sealing surface, each of abrasive grains constituting a grindstone has a flat face formed on its distal end. The sealing surface of the casting is ground by the grindstone while the flat face of each abrasive grain is held parallel to the sealing surface of the casting. Consequently, a plastic flow layer is formed on the sealing surface of the casting. Blowholes present within a predetermined range of depth of the casting from the sealing surface are collapsed as the result of formation of the plastic flow layer.Type: GrantFiled: January 2, 1998Date of Patent: December 7, 1999Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takefusa Sasamori, Motoshi Nakamura, Morihiro Sawada, Kazuya Nakata, Masafumi Yamaguchi
