Patent number: 8583641Abstract: A method of and apparatus for constructing a user profile using a content tag, a method of recommending digital content by using a user profile including a tag included in the digital content and a preference value for the tag. According to the methods and apparatus, a user profile is generated by using a content tag, and thus the taste of the user according to digital content consumption can be expressed in more varied ways. Also, by suggesting a method of generating a tag from web content, construction of a user profile for digital content having no tag is enabled. Furthermore, a tag extracted from digital content used by a user is included in a profile and it can be used for a variety of purposes, such as expansion of a comparison scope, use of preference keywords, providing of content links, and expansion of search scope.Type: GrantFiled: June 12, 2012Date of Patent: November 12, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Yun-ju Choe, Cheol-ju Hwang, Min-ho Lee, Sung-hwan Choi, Won-dong Yun, Soo-hong Park, Jeong-rok Jang, Sang-wook Cho

Patent number: 8520558Abstract: A quality of service (QoS) securing apparatus and method using a communication protocol is provided. The QoS securing method is performed by a reception side that is receiving data from a transmission side. The method includes generating information about a changed communication environment according to a change in a communication environment of the reception side, and transmitting the information to the transmission side. An exchange of information about a communication environment using the communication protocol between the reception side and the transmission side can inform the transmission side about resources of the reception side, link characteristics, characteristics of a link on a transmission path, etc., thereby securing a QoS of data communication between the reception side and the transmission side.Type: GrantFiled: December 21, 2006Date of Patent: August 27, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Yun-ju Choe, Cheol-ju Hwang, Soo-hong Park, Young-keun Kim, Han-sung Kim, Won-dong Yun, Min-ho Lee, Jeong-rok Jang

Patent number: 8463640Abstract: A method of adaptively updating a first recommended user group list of a first user connected to a network, in which a predetermined number of second users are selected from the first recommend user group list that is a list of users having a high similarity to the first user in consuming contents. A predetermined number of third users having a high similarity to the first user is selected from second recommend user group lists respectively of the selected second users possess. The first recommend user group list is updated to include the selected third users. As the preference of a user changes, the recommend user group may be reconfigured with updated recommend users by reflecting a corresponding preference. Also, quality contents can be provided by recommending a user of a corresponding terminal with the contents preferred by other users in the updated recommend user group list.Type: GrantFiled: January 6, 2009Date of Patent: June 11, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Jeong-rok Jang, Cheol-ju Hwang, Jae-hwang Lee, Min-ho Lee, Sung-hwan Choi, Sang-wook Cho, Yun-ju Choe

Patent number: 8379595Abstract: A method and apparatus for securing a quality of service (QoS) of data communication is provided. The method of securing the QoS of data being received by a mobile terminal at a reception side that performs a handover from a first network to a second network comprises generating a packet including information about the second network, transmitting the packet to a transmission side, and selectively performing the handover according to whether a packet including information in response to the packet is received. When a reception side performs a handover, a transmission side can be informed of information about the second network via the exchange of packets between the reception side and the transmission side, thereby securing a QoS of the data transmission.Type: GrantFiled: November 16, 2006Date of Patent: February 19, 2013Assignee: Samsung Electronics Co., Ltd.Inventor: Yun-ju Choe
