Latest Patents

Cai’s patent, “Query-Dependent Generative Descriptions for Videos Provided via a Search Result,” describes a method for creating descriptions of video resources in response to search queries. The system receives a video resource and generates a query for which that resource is relevant. It then processes a prompt containing the query and descriptive content related to the video through a generative model.

The query and generated description are stored when a groundedness score meets a specified threshold. This score measures how well the description aligns with the prompt. The description can then appear alongside the video resource in a search result.

Career Highlights

Cai’s patent reflects work at the intersection of generative models, video content, and search. The disclosed approach uses a groundedness check to help ensure that generated descriptions align with the information provided to the model.

Collaborations

Cai’s listed coworkers include Bhaskar Srinivas Gurram and Anurag Vyas. The available information identifies them as colleagues but does not specify their roles in the patent.

Conclusion

Chen Cai’s patent presents a query-aware approach to describing video resources in search results, combining generative models with a groundedness threshold to assess alignment.
