Publication number: 20240168988Abstract: A method is presented for enhancing search results by segmenting documents into smaller passages and utilizing those passages as the search unit. This method integrates the passage rankings from two search models to produce a new document ranking and arranges the documents accordingly. The ranking of document is also rearranged based on the proportion of passages taken from the same document versus the total number of passages in that document. The final search ranking system combines document-level and passage-level search rankings to rank documents. This method ensures that when conducting a passage search, the search results consider the general relevance of the entire document, which leads to better performance compared to searching only by document-level or passage-level searches.Type: ApplicationFiled: December 4, 2023Publication date: May 23, 2024Inventors: Sung-Bum PARK, Suehyun CHANG

Publication number: 20240163466Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. Coding decision information of a representative channel of a target block is shared as coding decision information of a target channel of the target block, and decoding of the target block is performed using the coding decision information of the target channel. Since the coding decision information of the representative channel is shared with an additional channel, repeated signaling of identical coding decision information may be prevented. By means of this prevention, the efficiency of encoding and decoding of the target block or the like may be improved.Type: ApplicationFiled: December 27, 2023Publication date: May 16, 2024Applicants: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE, RESEARCH AND BUSINESS FOUNDATION SUNGKYUNKWAN UNIVERSITYInventors: Dong-San JUN, Jung-Won Kang, Hyunsuk Ko, Sung-Chang Lim, Jin-Ho Lee, Ha-Hyun Lee, Byeung-Woo Jeon, Hui-Yong Kim, Jee-Yoon Park

Patent number: 11985117Abstract: A multifunction peripheral (MFP) includes user selectable functions that call home applications on the device that direct it to work cooperatively with cloud service providers. To avoid requiring users to login to each cloud service each time they use it, they are registered with an authorization server to establish and grant identity and authorization tokens. When a user logs in to an MFP, they are redirected to login to the authorization server which then sends tokens to the MFP identifying the user and their permissions and licenses. Home applications associated by the tokens are displayed for selection. Each time a home application using a cloud service is selected, a background application sends the user's session tokens with a service request to an associated cloud service resource server. The resource servers processes authenticated requests and return the result to the MFP which completes the selected home application function.Type: GrantFiled: February 22, 2022Date of Patent: May 14, 2024Assignee: TOSHIBA TEC KABUSHIKI KAISHAInventors: Peter McLain, Christopher Nguyen, Louis Ormond, Marianne Kodimer Kodimer, Chang Park, Silvy Wilson
