Publication number: 20250086685Abstract: An online concierge system assists users in identifying additional information about items in an image. Image regions are identified in the image that may correspond to unknown items and an item search space is determined for detecting items in the image regions based on a context of the image, such as items in a warehouse or a list of items delivered to a customer. The identified items are used to retrieve relevant item information that is included in a prompt for a language model to extract relevant information for the item. As such, the process may automatically process the image into relevant textual information about the pictured items. Applications may be used to assist vision-impaired users in distinguishing delivered items or quickly identifying and evaluating relevant information about items.Type: ApplicationFiled: September 7, 2023Publication date: March 13, 2025Inventors: Shubhanshu Mishra, Gia Young, Jennie Morgan Burger, Joseph Olivier, Brent Luna, Yuanzheng Zhu, Mackenzie Cala, Armand Raquel-Santos, David Zandman, Mia Martinez Barnett, Callie Bleckner, Mohammad Abdul-Rahim

Publication number: 20250061277Abstract: The disclosure herein describes using a deep learning model to identify topic segments of a communication transcript. A communication transcript including a set of utterances is obtained. The set of utterances is divided into a plurality of utterance windows, wherein each utterance window of the plurality of utterance windows includes a different subset of utterances of the set of utterances, and wherein each utterance of the set of utterances is included in at least one utterance window of the plurality of utterance windows. For each utterance window of the plurality of utterance windows, each utterance in the utterance window is classified as a topic boundary or a non-boundary using a deep learning model. Topic segments of the communication transcript are identified based on utterances of the set of utterances that are classified as topic boundaries. A communication transcript summary is generated using the communication transcript and the identified topic segments.Type: ApplicationFiled: December 15, 2021Publication date: February 20, 2025Inventors: Chenguang ZHU, Yang LIU, David Peace HUNG, Nanshan ZENG
