Information processing apparatus, data acquisition method, and program
First Claim
1. An information processing apparatus comprising a computer processor and a memory for storing instructions that when executed by the processor perform a method, the method comprising:
- selecting for prefetching at least one link destination from a plurality of link destinations, wherein the plurality of link destinations are a result of a search based on key information;
prefetching, before the at least one link destination is selected by user operation, information relating to a layout of a display screen and display control data including at least a structural unit in which the information relating to a layout of a display screen is written, the display control data and the information relating to a layout of a display screen existing at the at least one link destination selected for prefetching;
analyzing the display control data and extracting structural units included in the display control data, when the at least one link destination whose display control data has been acquired by prefetching is selected by the user operation;
generating, when the at least one link destination whose display control data has been acquired is selected by the user operation, a display screen created from first structured data for display control by mutually linking, except for a structural unit in which information relating to display control involving script processing is written, the structural units including at least the structural unit in which the information relating to a layout of a display screen is written, among the structural units extracted;
generating, when the link destination whose display control data has been acquired is selected by the user operation, a display screen created from second structured data for display control by mutually linking the structural units; and
displaying the display screen created from the first structured data, which is generated at a first time, and, at a second time when the display screen created from the second structured data is generated, replacing the display screen created from the first structured data with the display screen created from the second structured data.

Abstract
Provided is a data acquisition method including the steps of selecting one or more of at least one link destination, acquiring, before the link destination is selected, display control data including at least a structural unit in which information relating to a layout of a display screen is written, the display control data existing at the link destination selected in the previous step, extracting structural units included in the display control data before the prefetched link destination is selected, generating, before the prefetched link destination is selected, first structured data for display control by linking the extracted structural units in which information involving script processing is not written, generating, in a case the prefetched link destination is selected, second structured data for display control by linking the structural units, displaying a display screen using the first structured data, and redisplaying the display screen using the second structured data.

selecting for prefetching at least one link destination from a plurality of link destinations, wherein the plurality of link destinations are a result of a search based on key information; prefetching, before the at least one link destination is selected by user operation, information relating to a layout of a display screen and display control data including at least a structural unit in which the information relating to a layout of a display screen is written, the display control data and the information relating to a layout of a display screen existing at the at least one link destination selected for prefetching; analyzing the display control data and extracting structural units included in the display control data, when the at least one link destination whose display control data has been acquired by prefetching is selected by the user operation; generating, when the at least one link destination whose display control data has been acquired is selected by the user operation, a display screen created from first structured data for display control by mutually linking, except for a structural unit in which information relating to display control involving script processing is written, the structural units including at least the structural unit in which the information relating to a layout of a display screen is written, among the structural units extracted; generating, when the link destination whose display control data has been acquired is selected by the user operation, a display screen created from second structured data for display control by mutually linking the structural units; and displaying the display screen created from the first structured data, which is generated at a first time, and, at a second time when the display screen created from the second structured data is generated, replacing the display screen created from the first structured data with the display screen created from the second structured data. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A data acquisition method comprising the steps of:
-
selecting one or more of at least one link destination which is a result of search based on key information; acquiring, before the link destination is selected by user operation, display control data including at least a structural unit in which information relating to a layout of a display screen is written, the display control data existing at the link destination selected in the step of selecting a part of at least one link selection destination; analyzing the display control data and extracting structural units included in the display control data before the link destination whose display control data has been acquired prior to the user operation is selected by the user operation; generating, before the link destination whose display control data has been acquired prior to the user operation is selected by the user operation, first structured data for display control by mutually linking, except for a structural unit in which information relating to display control involving script processing is written, the structural units including at least the structural unit in which the information relating to a layout of a display screen is written, among the structural units extracted in the step of extracting structural units; generating, in a case the link destination whose display control data has been acquired prior to the user operation is selected by the user operation, second structured data for display control by mutually linking the structural units; displaying a display screen by using the first structured data generated in the step of generating first structured data; and redisplaying, upon the generation of the second structured data, the display screen by using the second structured data.

11. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer, causes the computer to execute a method, the method comprising:
-
selecting one or more of at least one link destination which is a result of search based on key information; prefetching, before the link destination is selected by user operation, display control data including at least a structural unit in which information relating to a layout of a display screen is written, the display control data existing at the link destination selected; analyzing the display control data and extracting structural units included in the display control data, before the link destination whose display control data has been acquired by the data prefetching is selected by the user operation; generating, before the link destination whose display control data has been acquired by the data prefetching is selected by the user operation, first structured data for display control by mutually linking, except for a structural unit in which information relating to display control involving script processing is written, the structural units including at least the structural unit in which the information relating to a layout of a display screen is written, among the structural units extracted by the structure analysis; generating, in a case the link destination whose display control data has been acquired by the data prefetching is selected by the user operation, second structured data for display control by mutually linking the structural units; and displaying a display screen by using the first structured data, and redisplaying, upon the generation of the second structured data, the display screen by using the second structured data.
