Publication number: 20220248066Abstract: Live broadcast interaction method, apparatus, device, and storage medium are provided. The method is applied in a live broadcast cooperative server connected to multiple live broadcast ends and multiple live broadcast service providers, and includes: receiving a live broadcast request sent by a first live broadcast end; providing a list of one or more connectable second live broadcast ends to the first live broadcast end; receiving a confirmation result from the first live broadcast end or a second live broadcast end; receiving original live broadcast data of the first live broadcast end and at least one second live broadcast end according to the confirmation result; processing the original live broadcast data to generate final live broadcast data; and sending the final live broadcast data to one or more live broadcast service providers. A connection across live broadcast service providers can be realized, and the scalability of live broadcast is improved.Type: ApplicationFiled: January 26, 2022Publication date: August 4, 2022Inventors: Shibo Liu, Jiandong Ding, Yongji He

Publication number: 20220101474Abstract: The present disclosure provides a method and system for analyzing and managing transportation. The method may include generating, for each of a plurality of geographic regions, a first graph representation based on transportation data relating to transport activities within the geographic region. The method may also include obtaining, for any two of the plurality of geographic regions, via a graph kernel based algorithm, a first similarity indicator measuring a similarity between the first graph representations of the any two of the plurality of geographic regions. The method may further include grouping, based on the first similarity indicators, the plurality of geographic regions into a plurality of groups. The method may also include, for each of the plurality of groups, identifying at least one featured transportation type of the group and associating a strategy to the group to promote or restrict transport activities of the at least one featured transportation type of the group.Type: ApplicationFiled: December 10, 2021Publication date: March 31, 2022Applicant: BEIJING DIDI INFINITY TECHNOLOGY AND DEVELOPMENT CO., LTD.Inventors: Weiming LIU, Jiandong Ding

Patent number: 11151680Abstract: Systems and methods for recommending transportation means are provided. The method may include obtaining current travel information of a target user and historical travel information and social information of the target user, respectively. The method may further include determining a user type based on the historical travel information, the user type being a first type or a second type. The method may further include, in response to determining that the target user is a user of the first type, determining a first clustering model based on the historical travel information; or in response to determining that the target user is a user of the second type, determining a second clustering model based on the social information. The method may further include recommending a transportation means to the target user based on the clustering model and the current travel information of the target user.Type: GrantFiled: April 18, 2019Date of Patent: October 19, 2021Assignee: BEIJING DIDI INFINITY TECHNOLOGY AND DEVELOPMENT CO., LTD.Inventors: Jiandong Ding, Xiaofei Zhou

Publication number: 20070196425Abstract: The present invention provides a thermosensitive and biodegradable microgel and a method of synthesizing such microgels. The thermosensitive and biodegradable microgel is synthesized from a macromer comprising a thermosensitive block polymer co-polymerized with a biodegradable moiety encapped with a cross-linkable or polymerizable moiety at either end. The microgels of the present invention are synthesized by inverse suspension polymerization of the macromers. The microgels are biodegradable into components that are non-toxic and easily removed from the body. The microgel of the present invention is temperature sensitive and is “intelligent” as well as biodegradable. The microgels are preferably used for the controlled release of a drug or in tissue engineering. Most preferably, the microgels are suitable for the control release of biologically active substances such as proteins.Type: ApplicationFiled: April 27, 2007Publication date: August 23, 2007Inventors: Jiandong DING, Wen Zhu, Biaobing Wang, Ying Zhang
