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.

Claims

1. An information processing apparatus comprising:

a link selection unit that selects one or more of at least one link destination which is a result of search based on key information;

a data prefetch unit that acquires, before the 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 link destination selected by the link selection unit;

a structure analysis unit that analyses the display control data and extracts structural units included in the display control data, in a case the link destination whose display control data has been acquired by the data prefetch unit is selected by the user operation;

a first structuring unit that generates, in a case the link destination whose display control data has been acquired by the data prefetch unit 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 unit;

a second structuring unit that generates, in a case the link destination whose display control data has been acquired by the data prefetch unit is selected by the user operation, second structured data for display control by mutually linking the structural units; and

a display control unit that displays a display screen by using the first structured data generated by the first structuring unit, and, at a stage the second structured data is generated by the second structuring unit, redisplays the display screen by using the second structured data.

2. The information processing apparatus according to claim 1, further comprising:

a connection establishment unit that establishes a connection to the link destination,

wherein the link selection unit further selects at least any of the link destination existing within a specific range of a display position of a position specifying object that is used for specifying a position on the display screen, the link destination currently displayed on the display screen and the link destination which has been selected specific times or more, and

wherein the connection establishment unit establishes a TCP connection to the link destination that the link selection unit further selected, before the link destination is selected by the user operation.

3. The information processing apparatus according to claim 2, wherein the link selection unit selects, as a link destination to which the TCP connection is to be established, a link destination whose round-trip time is a specific threshold or more, among the at least one link destination.

4. The information processing apparatus according to claim 3, wherein the link selection unit decides, according to a domain name or an IP address of the link destination, whether or not the link destination is to be selected as the link destination to which the TCP connection is to be established.

5. The information processing apparatus according to claim 1, further comprising:

a data acquisition unit that acquires the display control data and related data related to the display control data,

wherein the data acquisition unit handles a data acquisition request from the first structuring unit in priority to a data acquisition request from the second structuring unit.

6. The information processing apparatus according to claim 2, wherein the connection establishment unit acquires, when a host address of the link destination is decided, an IP address corresponding to the host address before prefetching of the display control data or establishment of the TCP connection.

7. The information processing apparatus according to claim 6, further comprising:

a cache memory in which the display control data and the related data acquired by the data acquisition unit upon requests from the first structuring unit and the second structuring unit are stored,

wherein the display control unit switches display based on data stored in the cache memory, at a time point of all the display control data required for display based on the second structured data having been stored in the cache memory.

8. The information processing apparatus according to claim 1, wherein the second structuring unit does not generate the second structured data in a case the structural unit in which the information relating to display control involving script processing is written is not present in the structural units extracted by the structure analysis unit.

9. The information processing apparatus according to claim 1, further comprising:

a display history storage unit that stores a history including a structural unit corresponding to content displayed on the display screen at a time of performing display based on the first structured data,

wherein the display control unit selects, at a time of switching to display based on the second structured data, a structural unit corresponding to content to be displayed on the display screen, based on display history stored in the display history storage unit.

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;

analysing 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, at a stage the second structured data is generated, the display screen by using the second structured data.

11. A program for causing a computer to realize:

a link selection function of selecting one or more of at least one link destination which is a result of search based on key information;

a data prefetch function of 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 by the link selection function;

a structure analysis function of analysing 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 prefetch function is selected by the user operation;

a first structuring function of generating, before the link destination whose display control data has been acquired by the data prefetch function 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 function;

a second structuring function of generating, in a case the link destination whose display control data has been acquired by the data prefetch function is selected by the user operation, second structured data for display control by mutually linking the structural units; and

a display control function of displaying a display screen by using the first structured data generated by the first structuring function, and redisplaying, at a stage the second structured data is generated by the second structuring function, the display screen by using the second structured data.
