Abstract: A collaborative bargaining system receives expressions of interest from potential buyers of an item. The collaborative bargaining system receives bids from sellers of the item. Each bid consists of a price per item based on a minimum quantity of items. A time limited exclusive opportunity is awarded to one seller of the item to obtain from the interest group a commitment to buy the minimum quantity of items at the price per item as bid by the one seller. Sales of the item are closed when the interest group commits to buy the minimum quantity of items.

Advertisements with high relativity are displayed in web page showing results of data search at the same time to attract the attention of user who initiates the search.

Abstract: An automatic knowledge management system, includes a knowledge base management module; an automatic search engine to execute the searching instructions of users to search searchable information in a knowledge base; an information filter module to identify information resulting from searching of said automatic search engine, to exclude information that does not satisfy a group of filtering conditions and to store information or its addresses that satisfy said group of filtering conditions into said knowledge base memory; and a searching condition connection module to compare the search conditions as input by one user for one search and/or the corresponding filtering conditions, with the respective groups of search conditions and/or their corresponding filtering conditions previously stored, and to provide to said one user information files and/or addresses of information files resulting from previous searching operations corresponding to such search conditions and/or filtering conditions if the current and pri

Abstract: A dynamic database index and management system essentially involving a multiple of user-defined data attributes used to depict the nature and type of stored data. The user defines attributes, defines subordinate relationships between attributes and determines which attributes are assigned to which data lots. Attributes may then be used for retrieval of the data.

Abstract: An automatic knowledge management system comprising: a knowledge base management module to accessibly store knowledge information in particular file formats or related file addresses into an adjustable knowledge tree structure in its knowledge base memory means; an automatic search engine to execute the searching instructions of users periodically or non-periodically to search searchable information in a wide filed knowledge base according to certain search conditions and to store results of such search into its information buffer memory means; an information filter module to identify information resulted from the searching of the automatic search engine, to exclude information that does not satisfy a group of filtering conditions and to store information or its addresses that satisfy said group of filtering conditions into said knowledge base memory means; and a searching condition connection module to compare the search conditions as input by one user for one search and/or the corresponding filtering condit

Abstract: The process of dividing sentences into phrases is automated. The sentence is divided into sub-sentences using statistical analysis. Then, the sub-sentences are into phrases, using statistical analysis. For example, for each pair of adjacent words in the sentence a metric is calculated which represents a strength of disconnection between the adjacent words. The sentence is divided into sub-sentences at locations in the sentence where the metric exceeds a first threshold.

Abstract: A method and system for providing an advertisement for a product or service on a personal electronic document accessible over a data network. A carrier provides the product or service to a user. The carrier also provides a document design application to the user. A server in communication with the data network receives the personal electronic document from a first computer in communication with the data network. The personal electronic document is constructed using the document design application. The personal electronic document is associated with the user. The personal electronic document is stored as data on a storage medium in communication with the data network. Advertisement information provided by the carrier is inserted in the personal electronic document. A second computer in communication with the data network is provided access over the data network to the personal electronic document stored on the storage medium. The second computer is associated with a visitor of the personal electronic document.
