Patent number: 11977570Abstract: Content of different formats may be sourced from various data sources such as content servers and ingested into a data integration server by an ingestion broker embodied on a non-transitory computer readable medium. The ingestion broker may normalize the content of different formats into a uniform representation that can be indexed and delivered across multiple digital channels for a variety of applications. The normalized content may be analyzed and semantic metadata may be determined from the normalized content. The normalized content can be semantically enriched by associating the semantic metadata and the like with the content. The semantic metadata can be stored in a semantic index that can be used for searching via the data integration server. During search, the semantic metadata can be instantiated as facets for user navigation and refinement of search criteria and additional semantic relationships can be assigned to the words in the normalized content.Type: GrantFiled: May 16, 2022Date of Patent: May 7, 2024Assignee: OPEN TEXT SA ULCInventors: Pascal Dimassimo, Steve Pettigrew, Martin Brousseau, Charles-Olivier Simard, Eric Williams, Francis Lacroix, Alex Dowgailenko, Agostino Deligia, Jean-Michel Texier

Patent number: 11877958Abstract: The invention concerns an implant that comprises an anterior part and a posterior part extending along a longitudinal axis and having respectively an anterior (A) and a posterior pole (E) both located on axis. The anterior and posterior parts extend each radially relative to axis, on either side thereof, the anterior and posterior parts having each two portions located on both sides of axis respectively when viewed in a sagittal plane. Each portion of the anterior part has a radial extension that increases from anterior pole (A) to a point (B, B?) where the anterior part ends and the posterior part begins, each portion of the posterior part having a radial extension decreasing from point (B, B?) to the posterior pole (E). The outer outline of each portion of the anterior part forms a curve having a radius of curvature that is greater at anterior pole (A) than at point (B, B?).Type: GrantFiled: March 13, 2018Date of Patent: January 23, 2024Assignee: KEJAKO SAInventors: Gilles Bos, Aurélien Maurer, David Enfrun, Michael Assouline, Pierre-Francois Isard, Pierre-Yves Maitre, Gabriel Delage, Charles-Olivier Zuber, Mario Carta, Moïse Seguin, Quentin Guyot

Publication number: 20230315773Abstract: In an auto-classification system, example documents whose content exemplifies a content category or classification can be imported into a classification model. The classification model is tested to assess accuracy. Based on the testing, metrics or other information can be provided as feedback to a user. The user can iteratively refine the classification model and keep re-running the classifications to view how each change to the classification model improves accuracy. If no user refinement is desired, the auto-classification system classifies documents utilizing the classification model. This technology enhances the overall transparency and defensibility of the auto-classification process.Type: ApplicationFiled: June 7, 2023Publication date: October 5, 2023Inventors: Charles-Olivier Simard, Alex Bowyer, Daniel Leclerc, Steve Molloy

Publication number: 20230297602Abstract: Methods, systems and computer-readable media enable various techniques related to semantic navigation. One aspect is a technique for displaying semantically derived facets in the search engine interface. Each of the facets comprises faceted search results. Each of the faceted search results is displayed in association with user interface elements for including or excluding the faceted search result as additional search terms to subsequently refine the search query. Another aspect automatically infers new metadata from the content and from existing metadata and then automatically annotates the content with the new metadata to improve recall and navigation. Another aspect identifies semantic annotations by determining semantic connections between the semantic annotations and then dynamically generating a topic page based on the semantic connections.Type: ApplicationFiled: May 23, 2023Publication date: September 21, 2023Inventors: Pascal Dimassimo, Steve Pettigrew, Martin Brousseau, Charles-Olivier Simard, Eric Williams, Francis Lacroix, Alex Dowgailenko, Agostino Deligia, Jean-Michel Texier
