Preferred embodiment describes in detail
The present invention is devoted to a kind of method and system that is used for choosing and upgrades the structured text arbitrary element automatically.The present invention preferably realizes by the network (for example the Internet or Intranet) that comprises two or many computing machines, but this is dispensable.In addition, the present invention also can realize on an independent computing machine, and the information on it in certain particular structured file will be upgraded by often (as manually) and the user wishes to browse by his designated time intervals the part of this document.And different, should be grasped by those of skill in the art by this point according to specific use executive routine for the type of structured text.
For the purpose that explains orally, the present invention will be described with reference to World Wide Web (hereinafter referred to as " network ") here, and structured text refers to " webpage ".But, be to be understood that the present invention is not only limited to network and webpage.Therefore, the structured document of the computer configuration of other type (preferred network) and other type also is operable.
The embodiment that carries out graphic extension among the present invention comprises a client or User Part and a server section.In this situation of network, the present invention allows the user to pick up and select interested element (fragment) from any webpage.And the present invention realizes with alternant way, and is configured to use known " cliping and pasting " editor example.In addition, the invention provides a kind ofly, can carry out formative enhancement mode " the webpage segment " that obtain.In addition, the present invention also provides to server one side and has safeguarded the needed support of up-to-date fragment.
Below will provide general explanation of the present invention, introduce notions more of the present invention and advantage to the reader.Subsequently, the detailed description of relevant various aspects of the present invention will provide.
The present invention allows the user to select different elements on the different web pages, is sent to the user again after the content that the user chooses is updated periodically.Selecting technology depends on specific realization mechanism and varies.
The present invention solves the geometry character that exists in the prior art and chooses problem with contents lost.For example, the present invention allows the user to choose stock quotation from certain one page, chooses nearest sports reports title from another page, and chooses weather forecast from another page or leaf again, or the like.The present invention upgrades the content in all these selected areas in the time interval that the user selects, then these selected areas are sent in user's the desktop computer.Different with the DIBS system, our system is not based on the selection district that geometric configuration is upgraded the user, but with user's the selection district and the fabric tight association of network text.Therefore, renewal process is more reliable, and As time goes on user's correlativity of selecting to distinguish still can be held.
Should be appreciated that the present invention can be applied in various forms of hardware, software, firmware, special purpose processors and their unitized construction.The present invention preferably is applied on the software, as being embodied in the program in the program storage device really.This class method can be loaded onto on the machine that has comprised any suitable structure, and performed by it.Preferably, this machine realizes that on computer platform this computer platform comprises hardware such as one or more central processing unit (CPU), random access memory (RAM) and input/output interface (I/O).Computer platform also comprises operating system and micro-instruction code.Here the part (perhaps both combinations) of the part of Shuo Ming various treatment progress and function or micro-instruction code or the program carried out by operating system.In addition, various other peripherals also will be connected on the computer platform, as additional data storage device and printing device.
It is to be further understood that because the parts and the method step of some composition systems that illustrate in the respective drawings are preferably realized in software, so the actual contact meeting between the system unit (or treatment step) varies according to the difference of programming mode of the present invention.
Fig. 1 is the diagram of critical piece in the system 100, and this system is used for choosing and automatically upgrades the arbitrary element of structured text by one embodiment of the present of invention.Three critical pieces among the present invention are: client's front-end edit instrument 102, database engine 104 and the webserver 106.These parts are divided into two groups: client portion (or customer) and server section (or server side).But the structure of other type also allows, and comprises at least one center section (deciding according to specific implementation).In the embodiment of this graphic extension of the present invention, client's front-end edit instrument 102 correspondences client portion, and database engine 104 and the webserver 106 correspondences server section.These parts correspondences three kinds of main tasks by the present invention's execution, and they are respectively to determine to select to distinguish, preserve these to select to distinguish, duplicate the selection district that these were saved from webpage.
Fig. 2 is a flowchart text about among Fig. 1 by the performed step of customer of the system of the embodiment of the invention.Edit page is loaded onto (step 202) in the web browser.The permission user selects some part in the webpage during edit page.In a preferred embodiment of the invention, edit page has the user interface controls of a floating toolbar form.
The URL of first page object (uniform resource address) is keyed in this user interface (step 204).The result is that page object is acquired.In case get this page object, customer's Topological Mapping (below be called t-mapping) just is created (step 206) for this page or leaf.T-is mapped in the step 206 and is created, so that be characteristic formation characteristic ID mapped in this page.T-mapping is a kind of mapping/data structure, it with the correspondence position informational linkage of the identifier of characteristic mapped in the structured text and these characteristics together, this positional information is corresponding to a text existence that provides.Certainly also may comprise the additional information relevant in the t-mapping with various characteristics.
Characteristic in the structured text may be, for example, and table, paragraph or the like.The identifier of mapped characteristic is called as " property identifier ".
Structured text is level normally, and its form of expression may include nested region.The T-mapping allows position and these the mapped characteristics of range index according to these characteristics.And the t-mapping allows nested region in the text presentation form and bottom text characteristics are associated.In the embodiment of this graphic extension of the present invention, to compare with the zone of limiting to, the zone that scope is bigger is presented at the more bottom of t-mapping.And in graphic embodiment, positional information is that the form with the fully-flattened coordinate exists.But, should be appreciated that other order relation also can be used to arrange the information in the t-mapping, for example, compare with zone in a big way, the narrow range zone appear at the t-mapping than bottom.And the information of other type also can be used to indicate the address of mapped information.
In other embodiments of the invention, the t-mapping is implemented as a kind of linking layer aggregated(particle) structure, has comprised the upper level node place of characteristic zone in structure in other characteristic zone in this structure.Each characteristic zone that is defined as being comprised in the zone of upper level node then occurs as the child node of this node.Got up by link flatly between blood brother's node, then got up between the node of Dai Yudai (father-son) by link vertically.Based on the explanation that provides here, a those of ordinary skill in the correlative technology field just can be associated t-and shine upon these and other similar implementation.
The user selects interesting areas (step 208a) in page object.Then, the user determines that its interested these zones will once refresh (step 208b) on what frequency.Next just determine whether also to exist other page object (the interested part that is selected is also arranged on it) (step 210).If exist, then return step 204.On the other hand, if there has not been other page object, these URL and property identifier of choosing the district just all are stored in the database engine 104 (step 212).
In case user's log-in, session just is activated.Then, cliping and pasting page or leaf will be created as described below.When the user withdraws from, perhaps pass through time-out period after, session just is closed.
Fig. 3 be flowchart text about among Fig. 1 by the performed step of server side in the system of embodiments of the invention.Server 106 reads property identifier/url list information (step 302) from database engine 104.Server 106 is looked ahead to create and is cliped and pasted the necessary target web of page or leaf then, and creates the t-mapping (step 304) of server side.In case when these webpages can utilize in the locality, utilize the text in the webpage that obtains of looking ahead just can be from wherein having won relevant content (step 306a).Then, these contents are adhered in the target html file that the final user can browse (step 306b).Next, the directed final objective html file of browser (step 308).Fig. 4 is the diagram that has illustrated by the execution result of those steps among Fig. 2 of embodiments of the invention and Fig. 3.
Front-end edit instrument 102 allows user's chosen content from different webpages.It provides a kind of simple mechanism to be used for choosing content from different webpages, as shown in Figure 4.The rectangle that can change size is used to draw a circle to approve selected zone.Specific when regional when having selected from certain one page, the characteristic of its bottom just is determined, and is stored in the database engine 104 as property identifier.The user also will specify him to wish how long to refresh content one time.
At server side, the page or leaf that is selected will be looked ahead.Then, the t-of server side mapping is generated from the HTML source of this page.Next, utilize in the editing process property identifier of determining, the relevant selection district in these pages can be created again, and is adhered to and can allows in the page object that the user browses.This process illustrates on the following demifacet of Fig. 4.
Introducing the mechanism of using context-sensitive below shines upon text and is mapped as some descriptions that the basis is carried out the selection of Web content and duplicated the advantage that is had with t-.At first, choice mechanism is independent of geometric configuration, browser or platform factor.Secondly, if the structure of webpage once changed sometimes, the t-mapping of client and server end may be asynchronous, and the user can be prompted to be necessary to update the content of this page.The 3rd, in case a part of text is chosen, no matter how this part changes, server can both retrieve the selected architectural characteristic of text, promptly allows the form of expression of the context-sensitive of information.The 4th, the process that generates the t-mapping will be followed the level attribute of text structure.Even it is incomplete selecting the district, because the scope of choosing is known, therefore, server total energy acquisition of information is rebuild the part that the text is lost, so that better show.
Although the embodiment of this graphic extension here describes with reference to corresponding accompanying drawing, be to be understood that, native system and method are not only limited to these definite embodiment, and under the condition that does not deviate from scope and spirit of the present invention, those of skill in the art can carry out various forms of variations and modification.All such changes and modifications all are included in the scope of the present invention as being intended that from illustrating the additional right descriptions.
