Patent number: 11676702Abstract: Presented herein are methods, systems, devices, and computer-readable media for image annotation for medical procedures. The system operates in a parallel manner. In one flow, the system starts from clinical terms and image and applies image detection module in order to get visual candidates for related radiological finding and provide them with semantic descriptors. In the second (parallel) flow, the system produces a list of prioritized semantic descriptors (with probabilities). The second flow is done by application of a reverse inference algorithm that uses clinical terms and expert clinical knowledge. The results of both flows combined by matching module for detection the best candidate and with limited user input images can be annotated. The clinical terms are extracted from clinical documents by textual analysis.Type: GrantFiled: December 16, 2019Date of Patent: June 13, 2023Assignee: International Business Machines CorporationInventors: Ella Barkan, Pavel Kisilev, Eugene Walach

Patent number: 10387454Abstract: This invention relates to a method and system for creating Big Data applications that can be executed on heterogeneous clusters. The applications can be executed on a particular platform, such as SPARK or UIMA-AS, but the method and system are able to translate the input to these targeted platforms without the developer needing to tailor the application specifically to the platform. The method and system are based on the use of an execution dependency graph, a cluster configuration, and a data size to create a stages table. The stages table is then optimized to increase the overall efficiency of the heterogeneous cluster. The stages table is then translated into a platform specific Big Data application.Type: GrantFiled: August 2, 2016Date of Patent: August 20, 2019Assignee: International Business Machines CorporationInventors: Flora Gilboa-Solomon, Eugene Walach, Simona Rabinovici-Cohen

Patent number: 9928450Abstract: A computer-implemented method for automating interaction with a computer system includes linking a control computer system to an input interface and to an output interface of a client computer system, which is operative for producing user interface images on a display device. The control computer system executes distinct software modules that include a virtual operator for simulating actions of a human operator. Execution of the software modules causes the control computer system to capture an image from the output interface, and to recognize information in the image. In response to the information, the virtual operator controls an input device to automatically execute predetermined operations on the client computer system via the input interface.Type: GrantFiled: June 2, 2014Date of Patent: March 27, 2018Assignee: International Business Machines CorporationInventors: Amir Geva, Eugene Walach
