The present invention aims to effectively restrict access of a general user to an inappropriate information piece at the judgment of an information manager. In order to pick up a desired information from an information storage medium or an information communication network while excluding inappropriate information, an information manager inputs suitability of information (a teacher signal) to an information presented at a user terminalto a group profile learning unitand prepares a group profile reflecting suitability of the information as specified by the information manager using the teacher signal. At a score calculating unit, a score signal indicating suitability of information is calculated for each information using the group profile, and access of an information user in a group to inappropriate information is restricted.

Information filtering system and information filtering method

In an e-commerce system which rearranges merchandise information pieces distributed to a consumer to match preferences of the consumer based on a personal profile with which various keywords contained in the merchandise information pieces and evaluation values corresponding to the keywords are registered where the evaluation values are learned in advance based on preferences of the consumer, while withdrawing a charge of merchandise from an account designated by the consumer to pay to the seller when receiving an order from the rearranged merchandise information pieces, an order for merchandise from the merchandise information pieces distributed to one consumer is placed using the personal profile of another consumer.

E-commerce system and method

A method and an apparatus for retrieving images which allows easy retrieval of a desired image from an image database stored in an electronic or optical recording medium or a communication network. As the first step of searching, through the menu entry section, the user enters multi-leveled retrieval requests for the keywords associated with an image. Received the requests, the retrieval section evaluates the user's necessity for the image based on at least the entered requests and the number of the requests. Then the retrieved image is displayed on the screen, according to the calculated necessity. The method and apparatus thus provide the user with a much-needed image in order of precedence by qualifying the user's necessity for the image.

Method and apparatus for image retrieval

An information inquiry support apparatus including means for creating a profile, that is, an evaluation table about each one of plural key words expressing the information content, relating to the user's concern, on the basis of the evaluation about plural pieces of information by the user evaluating presence or absence of concern about presented plural pieces of information, means for entering the specific information for inquiry, information evaluation means for calculating the need signal quantitatively expressing the degree of concern about the specific information for each user by using the profile, and means for quantitatively evaluating the fitness for inquiry, by the magnitude of the value of the need signal, and issuing each name of the plural individual and/or group users.

Method for manufacturing zinc oxide whiskers

A photoconductive cell comprises a photodetector section which consists of an aggregate of tetrapod-like zinc oxide whiskers. Each whisker consists of a core and needle-shaped crystals extending in four different directions from the core. Since this novel tetrapod-like zinc oxide whisker consists of single crystal zinc oxide, it suffers less deterioration. In addition, since the single crystals are transparent and an aggregate thereof has a high porosity, light tends to enter deep portions of the cell so that it exhibits high sensitivity.

Photoconductive cell with zinc oxide tetrapod crystals

Whiskers of zinc oxide whose crystal structure includes a central body and four needle crystal projections radially extending from said central body are described. The whiskers are so unique a structure that they are applicable to various materials such as metals, resins, ceramics and the like as a reinforcing material. The whiskers may be in the form of a mixture of whiskers of zinc oxide having crystal structures including two, three, four and/or five needle crystal projections. A method for preparing such whiskers is also described.

A metal composition comprising zinc oxide whiskers dispersed in a metal matrix. The whiskers comprise at least one needle crystal having a basal part whose diameter is from 0.7 to 14 micrometers and a length from the basal part to its tip of from 3 to 200 micrometers. The metal composition is isotropically reinforced with respect to mechanical strength and is significantly improved in free cuttability.
