A computer system for conducting electronic commerce. The system provides multiple electronic shopping carts for each user. Each electronic shopping cart has an indication of items currently within the electronic shopping cart and billing and shipment information. The system generates a display that identifies each of the electronic shopping carts and sends the generated display to a user computer system. The system then receives a selection of one of the identified electronic shopping carts from the user computer system and receives a selection of an item from the user computer system. In response to receiving the selection of the item, the system adds the item to the selected electronic shopping cart. The system then receives an indication to checkout the items in the selected electronic shopping cart from the user computer system. In response to receiving the indication to checkout, the system ships the items in the selected electronic shopping cart in accordance with the shipment information of the selected electronic shopping cart and bills for the items in the selected electronic shopping cart in accordance with the billing information for the selected electronic shopping cart. The system thus allows a user to select each of the electronic shopping carts for adding items to each electronic shopping cart.

A hot topic extraction apparatus for extracting a hot topic from information includes an information collection unit, an information storage unit, and a hot topic extraction unit. The information collection unit collects a document from an information source. The information storage unit stores collected information. The hot topic extraction unit extracts a document from the information storage unit while the information collection unit collects the document, and retrieves a document from the retrieved document, thereby extracting a hot topic from information contained in various information sources, not extracting a hot topic from a given document.

Hot topic extraction apparatus and method, storage medium therefor

A computer implemented method and system enable users to create a server-less shared space providing access to other users. By providing access to such spaces via a visual presentation, the system renders content available for access by other group members. Access is sometimes provided through propagation of metadata or other uniquely identifying indicia associated with the shared space to all group members.

Systems, methods, and computer products that efficiently determine useful dimensions associated with a database when employing OLAP processing techniques. The present invention enables a user to see at a glance in which queries certain columns and tables are used. The present invention may be implemented with a query miner module that may include a query browser module that improves browsing through queries and their components over the past. The preferred embodiment of the present invention provides an easy to use graphical interface showing the queries, tables, and columns in a tree structure. Further, the preferred embodiment of the present invention presents information about relationships and dimensions associated with a database and about columns, tables, and queries to the user without discernable lag time between the user's request and the generated information.

Only important portions in all of messages are extracted in the halfway or after the end of a discussion and are allowed to be referred to the user. The time for discussion is reduced, thereby smoothly proceeding a conference. An electronic conference system is constructed in an electronic conference system server in a manner such that a plurality of user clients are connected to the electronic conference system server through a network (not shown). The electronic conference system is made up of a message database, a message relation extracting unit, a message type setting unit, a message input and display unit, and an electronic conference summarizing system. The electronic conference summarizing system is constructed by a discussion path specifying unit, a message merging unit, a duplication message deleting unit, and a message summary file. All of the conclusions derived from a subject and its discussion tree are extracted, unnecessary portions such as quotations or the like are deleted, and the correspondence of questions and answers is arranged and is formed as a summary.

PROBLEM TO BE SOLVED: To classify articles for every unity of stories by storing the sets of articles, analyzing the reference relation, calculating the feature functions of the articles on the tree structure display screen of a link structure and cutting a link between nodes having a large change. SOLUTION: An article storage device 1001 stores articles, a reference relation analysis device 1008 analyzes the reference relation between plural articles 1002 and a tree structure display device 1009 displays this reference relation data 1007 on a tree structure display screen 1003. At this stage, the articles are displayed by a node and a reference relation is displayed by the link from an article to be referred to a referred article. A tree structure operation unit 1010 makes the descendant node of the node designated by a pointing device 1006 unseen from this tree structure display screen 1003. Further, when the difference of feature vector showing the contents of articles with each other between nodes which are in a parental relation is a prescribe value or more, a topic dividing device 1012 cuts the link between these nodes and makes a separate tree as an independent topic.

PROBLEM TO BE SOLVED: To provide a mail-order sale method which enables a customer to examine a commodity which was examined before without looking for commodities every time and informs the customer that the stock of the examined commodity is small and the commodity becomes a special-price commodity as to mail-order sale using a communication line. SOLUTION: On the mail-order sale side, a commodity selecting process part 1, a commodity information processing part 2, a commodity guiding process part 3, a customer information data base 4, and a commodity information data base 5 are provided, and commodities which are sold by mail are shown and seen by using the communication line, a commodity is picked up as a purchase candidate, and the picked-up commodity is stored in the data base 4 as customer information. When the commodity is examined again, picked-up commodity stored in the data base 4 are read out and shown to the customer. When the price of the picked-up commodity has been changed or runs out of stock, information on that is reported to the customer who picked up the commodity. COPYRIGHT: (C)1997,JPO

PROBLEM TO BE SOLVED: To enable staffs offer all necessary information to customers and to immediately give advice to them by judging automatically information which are necessary for the staffs and not acquired yet by them and then questioning the customers on such information. SOLUTION: When a task is known, the type of this task is inputted to a task designation means 1006. The means 1006 instructs a shared memory server 1003 to acquire the customer information on the relevant task. The server 1003 checks the customer information necessary for the task via a staff task question item definition data base 1009. If the necessary information is not contained in the data base 1009, the server 1003 instructs an information acquisition interaction means 1005 of a customer terminal 1001 to question a customer A. Then the acquired customer information are stored in a customer information data base 1010. Thus, a shared system of such a constitution automatically decides the information that are necessary and not acquired yet by the staffers 1 and 2 and then questions the customer A on such information. Thereby, the staffers can immediately give advice to the customer A. COPYRIGHT: (C)1997,JPO

Inter-staff information sharing system

PROBLEM TO BE SOLVED: To manage the learner's right of access to learning resource and to efficiently monitor the state of learning. SOLUTION: In the system for supporting cooperative learning, a plan of learning and conditions of monitoring learning are described in advance based on activity model data that can express the relation between a role and an action to the learning resource and learning process definition data for managing the level of learning. A cooperative learning server, when it receives a request from a learner client for the operation of the learning resource, specifies the present level of learning and the role of the learner by an access management means and judges whether or not the operation of the learning resource is permissible.
