Patent number: 7333769Abstract: A client machine receives Web data including a learning material part from a learning server in an e-Learning center to display it as an Web page. The Web page includes a circle graph that represents the intelligibility of all learners who studied the learning material and a pair of bar graphs that represent the ratio of the achievers in the finishers who could not understand the learning material. A learner can make use of the status information represented by the graphs to his or her learning. After attending the learning material part, a learner clicks an “Understood” button or a “Not Understood” button to inform one's intelligibility to the learning server.Type: GrantFiled: October 29, 2002Date of Patent: February 19, 2008Assignee: Fujitsu LimitedInventors: Shunichi Kamikawa, Hiroshi Kuzumaki, Keiko Chida, Ryusuke Momose

Patent number: 7171155Abstract: A learner clicks “Understood” button when he or she could understand a learning material or clicks “Not Understood” button when he or she could not understand. When the “Not Understood” button is clicked, the learning server machine transmits an explanation choice information to display a Web page including a knowledge tree that shows a structure of the learning material. The Web page contains headings of explanations and choosing ratios as end-nodes of the knowledge tree. The explanation describes the learning material in detail. The choosing ratio is a ratio of each of the explanations chosen by learners who attended the same lecture using the same learning material.Type: GrantFiled: September 30, 2002Date of Patent: January 30, 2007Assignee: Fujitsu LimitedInventors: Shunichi Kamikawa, Hiroshi Kuzumaki, Keiko Chida, Ryusuke Momose

Patent number: 6932612Abstract: Learning materials each of which consists of learning material units are stored in a learning material DB. Keywords corresponding to the respective learning materials are stored in the learning material evaluating table. A keyword-unit table defines which learning material units include the respective keywords. A learner clicks an Understood button when the learner understand the current unit. After the learner finishes to attend the current learning material, the keywords corresponding to the units in which the Understood button was clicked are specified based on the keyword-unit table. A learning material whose keywords are in the best agreement with the keywords specified is selected as a learning material to improve ability of the learner in the strong field based on the learning material evaluating table. In the same manner, a learning material to supplement the weak field is selected based on a history of clicks of a Not Understood button.Type: GrantFiled: September 30, 2002Date of Patent: August 23, 2005Assignee: Fujitsu LimitedInventors: Shunichi Kamikawa, Hiroshi Kuzumaki, Keiko Chida, Ryusuke Momose

Patent number: 6801752Abstract: When a client computer informs that a learner cannot understand the current learning material unit, a server computer specifies keywords linked with the current learning material unit that is attended by the learner as a first keyword set and specifies keywords linked with one of the learning material units that are already attended by the learner as a second keyword set. The server computer extracts keywords that are common between the first and second keyword sets as a selectable keyword set and transmits a list of keywords within the selectable keyword set to the client computer. When the client computer informs the keyword chosen by the learner, the server computer specifies the learning material unit that corresponds to the keyword chosen by the learner based on the keyword information and resends the specified learning material unit to the client computer.Type: GrantFiled: September 30, 2002Date of Patent: October 5, 2004Assignee: Fujitsu LimitedInventors: Shunichi Kamikawa, Hiroshi Kuzumaki, Keiko Chida, Ryusuke Momose

Patent number: 6769917Abstract: In an education system using a network, a method for automatically detecting a defective part in an education material and for indicating the defective part is provided. A defective information storing means for storing a defect point correlation with a portion of an education material is provided. When the system receives a question from a student's terminal PC, a defect point of a corresponding portion of an educational material, in the defective information storing means, is updated, based on the received question. By this update, whenever a question is sent from a student's terminal, a defect point stored correlation to a portion of an educational material is accumulated. It is judged whether the defect point reaches a predetermined threshold value, and the corresponding portion of the educational material is transmitted to a terminal of a system administrator, based on the result of the judgement.Type: GrantFiled: November 6, 2002Date of Patent: August 3, 2004Assignee: Fujitsu LimitedInventors: Akio Fujino, Hiroshi Kuzumaki, Shunichi Kamikawa, Norio Takeda, Hitoshi Ozawa

Patent number: 6755662Abstract: In a method for presenting questions by a host computer receiving questions from users, a question most suitable to an user can be presented. In an education system wherein plurality of students' personal computers PC are connected to an education center through a network, at the time of the FAQ search from a student, a plurality of FAQ questions are presented in the order appropriate to the student, by matching the FAQ level and FAQ keywords to the student's level and the keywords learned by the student. The student can easily select a question compatible with his/her own question, from the presented questions.Type: GrantFiled: November 6, 2002Date of Patent: June 29, 2004Assignee: Fujitsu LimitedInventors: Akio Fujino, Hiroshi Kuzumaki, Shunichi Kamikawa, Norio Takeda, Hitoshi Ozawa
