Publication number: 20240112804Abstract: A computer-implemented method for matching unstructured text to ontology entities in a clinical ontology is described. The method includes receiving one or more clinical notes associated with a patient; for each of the one or more clinical notes: extracting, using a neural network, one or more text spans from unstructured text in each clinical note, each of the one or more text spans identifying a respective input phrase in the unstructured text; for each of the one or more text spans, matching, using a text matcher, the text span with a respective output ontology entity from an ontology, the respective output ontology entity relating to a clinical condition of the patient; and outputting data defining the one or more text spans and the respective output ontology entity for each of the one or more text spans.Type: ApplicationFiled: October 2, 2023Publication date: April 4, 2024Inventors: Itay Laish, Uri N. Lerner, Aviel Atias, Natan Potikha, Ayelet Benjamini

Patent number: 11847176Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for correcting entity names. One method includes receiving texts and deriving a plurality of name-context pairs from the texts. The method further includes calculating a context consistency measure for each name-context pair and storing context-entity name data representing the name-context pairs. Another method includes identifying an entity name and one or more context terms from a query and generating candidate names for the entity name. The method further includes determining a score for each of the candidate names, selecting a number of top scoring candidate names, and using the selected candidate names to respond to the query.Type: GrantFiled: December 20, 2018Date of Patent: December 19, 2023Assignee: GOOGLE LLCInventors: Lawrence J. Brunsman, Matthieu Devin, Uri N. Lerner, Simon Tong

Patent number: 9507858Abstract: One embodiment of the present invention provides a system that merges similar clusters of conceptually-related words in a probabilistic generative model for textual documents. During operation, the system receives a current model, which contains terminal nodes representing random variables for words and contains cluster nodes representing clusters of conceptually related words. Nodes in the current model are coupled together by weighted links, wherein if a node fires, a link from the node to another node causes the other node to fire with a probability proportionate to the weight of the link. Next, the system determines whether cluster nodes in the current model explain other cluster nodes in the current model. If two cluster nodes explain each other, the system merges the two cluster nodes to form a combined cluster node.Type: GrantFiled: November 27, 2012Date of Patent: November 29, 2016Assignee: Google Inc.Inventors: Uri N. Lerner, Michael E. Jahr

Patent number: 9418335Abstract: A method may include receiving, at one or more processors, a current model. The current model may include a group of nodes representing words, at least one cluster of nodes representing related words, and a group of links. Each link may connect two nodes of the group of nodes. Each link may include a corresponding weight. The method may further include applying, by one or more processors, a set of training documents to the model to produce new weights for the group of links to create a new model; and making, by one or more processors, the new model the current model.Type: GrantFiled: May 4, 2012Date of Patent: August 16, 2016Assignee: Google Inc.Inventors: Uri N. Lerner, Michael Jahr

Patent number: 8180725Abstract: Some embodiments of the present invention provide a system that selects links while updating a probabilistic generative model for textual documents. During operation, the system receives a current model, which contains terminal nodes representing words and cluster nodes representing clusters of conceptually related words, wherein nodes in the current model are coupled together by weighted links, wherein if a node fires, a link from the node to another node is activated and causes the other node to fire with a probability proportionate to the weight of the link. Next, the system applies a set of training documents containing words to the current model to produce a new model. While doing so, the system: determines expected counts for activations of links and prospective links; determines link-ratings for the links and the prospective links based on the expected counts, and selects links to be included in the new model based on the determined link-ratings.Type: GrantFiled: July 21, 2008Date of Patent: May 15, 2012Assignee: Google Inc.Inventors: Uri N.

Publication number: 20100211894Abstract: Among other disclosed subject matter, a computer-implemented method includes identifying a first object that belongs to a first domain. The method includes identifying, using the first object, at least a first cluster node in a generative model that includes a plurality of first cluster nodes having weighted relationships to respective ones of a plurality of second objects. The method includes identifying, in response to identifying the first object, at least one of the second objects, the second object belonging to the first domain and being identified using the first cluster node and its respective weighted relationship.Type: ApplicationFiled: February 18, 2009Publication date: August 19, 2010Applicant: GOOGLE INC.Inventors: Michael E.
