TL;DR: In this paper, the superimposed sum of a replacement weight index W and similarity S is calculated by referring to a substitute weight index database 29 and a replacement candidate database 28 with similarity about each retrieval expression to evaluate the validity of replacement, and to execute information retrieval in order of the high evaluation result.
Abstract: PROBLEM TO BE SOLVED: To provide an information retrieval device for retrieving information by extending input conditions to a retrieval keyword close to the request of a user SOLUTION: When condition data are input by a user, all the combinations including an original keyword and a similar keyword are generated as the list of retrieval expressions from an individual retrieval keyword Then, the superimposed sum of a replacement weight index W and similarity S is calculated by referring to a replacement weight index database 29 and a replacement candidate database 28 with similarity about each retrieval expression to evaluate the validity of replacement, and to execute information retrieval in the order of the high evaluation result The replacement weight index W is defined as an index showing how far the keyword can be replaced with another keyword, and the similarity S is defined as an index showing the scale of the semantic similarity of the keywords The replacement weight index W or the similarity S are set by statistically deriving a value following the request of the user COPYRIGHT: (C)2009,JPO&INPIT

TL;DR: In this paper, a navigation device shows a map by a perspective drawing method (a bird's-eye drawing method) on a display, and indicates an own vehicle as an icon 100.
Abstract: PROBLEM TO BE SOLVED: To provide an image display method by which a menu display that facilitates an operator's view is displayed in a navigation device which performs a guidance by displaying a map screen.SOLUTION: The navigation device shows a map by a perspective drawing method (a bird's-eye drawing method) on a display, and indicates an own vehicle as an icon 100. If the operator chooses an icon 110from an upper-level menu 110, the menu 110 moves to the background of the screen with its size reduced, and the selected icon 110is placed to a vanishing point 130 in the map display. A lower-level menu 120 is displayed instead of the menu 110 near the approximate center of the screen. At this time, the menu 110 is displayed with an accent expression to show a different status from the menu 120.

TL;DR: In this paper, the authors present an electronic apparatus that includes an image providing sections 11, 14, 22 that provide image information; a display section 13 that displays image information, a display control section 21 that controls display of the image information and display operation sections 12, 13 P that instructs the display control Section 21 to display the information.
Abstract: PROBLEM TO BE SOLVED: To provide an electronic apparatus having good operability and a display method thereof.SOLUTION: An electronic apparatus 10 of the invention includes: image providing sections 11, 14, 22 that provide image information; a display section 13 that displays the image information; a display control section 21 that controls display of the image information that is input from the image providing sections 11, 14, 22 on the display section 13; and display operation sections 12, 13 P that instruct the display control section 21 to display the image information. The image control section 21 displays a first image on a first area 31 of a display screen 30 in the display section 13 in response to a display instruction from the display control sections 12, 13 P, displays a second image on the first area 31 in response to a display instruction from the display control section to display the second image, and also displays the first image on a second area 32 that is smaller in area than the first area 31 and is adjacent to the first area 31 with either one of the sides being in contact with one side of the first area 31.
