  • Publication number: 20260093898
    Abstract: Examples relate to a system including a processor that can perform certain operations. The operations can include obtaining input text. The operations also can include generating a set of vectors from an ensemble of machine-learning models based on the input text. The ensemble of machine-learning models can include a pre-trained language model configured to determine capitalization for mixed cases and acronyms, a pre-trained named entity recognition (NER) model configured to determine capitalization for general proper nouns, and a question-answer NER (QA-NER) model configured to determine capitalization for brand names. The QA-NER model can include a transformer language model and a linear layer. The operations additionally can include generating corrected sentence-case text by modifying capitalization of the input text based on the set of vectors and outputting the corrected sentence-case text on a draft advertisement user interface. Other embodiments are described.

  • Publication number: 20260064764
    Abstract: Systems and methods for retrieving and providing images are disclosed. An example system receives, from a user device, a request for an image. The system determines, using a machine-learning model, search embeddings based on the request; filters image data based on the request to identify a filtered set of the image data; and obtains a subset of the image embeddings corresponding to the filtered set of the image data. The system further determines based on a comparison of the search embeddings and the subset of the image embeddings, recommended image data, and causes presentation of the recommended image data at the user device. In response to selection of the recommended image data, the system provides the recommended image data to the user device.

  • Patent number: 12561354
    Abstract: Systems and methods of item-specific keyword recommendation are disclosed. An item data structure including an item title is received and at least one item embedding is generated by applying a first trained semantic mapping model to the item title. The first trained semantic mapping model includes a first semantic mapping framework. The at least one item embedding is compared to a set of keyword embeddings representative of a set of platform-relevant keywords and a set of item-specific recommended keywords is selected from the set of platform-relevant keywords based on a similarity between the at least one item embedding and each embedding in the set of keyword embeddings. The item title is modified to include at least one of the set of item-specific recommended keywords and an interface including the modified item title is generated.

  • Patent number: 12099540
    Abstract: Systems and methods of generating keyword-specific content are disclosed. A request for including a keyword is received and the keyword is classified as one of catalog related or unrelated. When the keyword is catalog related, the keyword is categorized in a category associated with the catalog and at least one term in the keyword is categorized in a facet category associated with the catalog. A content template is obtained. The content template is a category specific template when the keyword is catalog related and a generic template when the keyword is catalog unrelated. The category specific template is populated with the at least one term at a position associated with the one of the plurality of facet categories. Responsive content including the category specific template populated with the at least one term when the keyword is catalog related and the generic template when the keyword is catalog unrelated, is transmitted.
