  • Patent number: 11487947
    Abstract: Techniques are provided for using machine learning techniques to analyze textual content. In one technique, a potential item is identified within a document. An analysis of the potential item is performed at multiple levels of granularity that includes two or more of a sentence level, a segment level, or a document level. The analysis produces multiple outputs, one for each level of granularity in the multiple levels of granularity. The outputs are input into a machine-learned model to generate a score for the potential item. Based on the score, the potential item is presented on a computing device. In response to user selection of the potential item, an association between the potential item and the document is created. The association may be used later to identify a set of users to which the document (or data thereof) is to be presented.

  • Patent number: 11481448
    Abstract: During operation, the system obtains a first embedding produced by an embedding model from an input string representing an entity and a hierarchy of clusters of embeddings generated by the embedding model from a set of standardized entities. Next, the system searches the hierarchy of clusters for a subset of the embeddings that are within a threshold proximity to the first embedding in a vector space. The system then calculates embedding match scores between the input string and a first subset of the standardized entities represented by the subset of the embeddings based on distances between the subset of the embeddings and the first embedding in the vector space. Finally, the system modifies, based on the embedding match scores, content outputted in response to the input string within a user interface of an online system.

  • Publication number: 20220317113
    Abstract: The invention discloses a method for screening a therapeutic target of acute radiation-induced gastrointestinal syndrome and use of TIGAR target in the preparation of a medicine for treating radiation-induced gastrointestinal syndrome. The CreERT-loxP transgenic mouse model is used, in which quiescent intestinal crypt stem cells are effectively promoted to proliferate after exposure to high-dose ionizing radiation, to screen a therapeutic target that still has a therapeutic effect for radiation-induced gastrointestinal syndrome 18-24 h after ionizing radiation. Gene splicing occurs in particular cells in the CreERT-loxP transgenic mice only after the injection of tamoxifen, thereby regulating gene expression. The actual situation of initial exposure and then treatment after a nuclear accident is well simulated, so the invention is of great practical significance.
