Definitions

  • This invention relates to segmenting, transforming, and viewing electronic documents.
  • People often access electronic documents such as web pages, text files, email, and enterprise (proprietary corporate) data using desktop or laptop computers that have display screens that are larger than 10 inches diagonally and using connections to the Internet that have a communication rate of at least 28.8kbps.
  • Electronic documents are typically designed for transmission to and rendering on such devices.
  • Internet-enabled devices like mobile phones, hand-held devices (PDAs), pagers, set-top boxes, and dashboard-mounted microbrowsers often have smaller screen sizes, (e.g., as little as two or three inches diagonally across), relatively low communication rates on wireless networks, and small memories. Some of these devices cannot render any part of a document whose size exceeds a fixed limit, while others may truncate a document after a prescribed length. Accessing electronic documents (which often contain many paragraphs of text, complex images, and even rich media content) can be unwieldy or impossible using these devices. Automatic content transformation systems convert electronic documents originally designed for transmission to and rendering on large-screen devices into versions suitable for transmission to and rendering on small-display, less powerful devices such as mobile phones.
  • the invention features a method that includes altering portions of a text of an original version of a digital document to produce a revised version of the digital document in which the text is shorter than the text of the original document, receiving over a communication channel a request for the digital document from a device connected to the channel, and transmitting the revised version over the communication channel in response to the request.
  • Implementations of the invention include one or more of the following features.
  • the altering includes reducing the size of an image included in the original document, for example, by image compression, resampling, or conversion from color to black-and-white.
  • the altering of portions of the text includes applying more than one transformation selectively to the text. Transformations to be applied to the text as part of the altering step are selected based on preferences associated with the device.
  • the preferences are associated with the device based on a unique identifier of the device.
  • the preferences are stored in advance of the request for a document.
  • the preferences are stored in a database associated with a server.
  • the preferences are indicated by the user through the interface of the device.
  • the preferences are indicated by the user through the interface of a device other than the device from which the request for the digital document is made.
  • the preferences are indicated on a form provided from a server.
  • the preferences are stored for each device from which requests for documents may be received.
  • the preferences are stored for each type of device from which requests for documents may be received.
  • the preferences are stored on the device using a cookie mechanism.
  • the altering depends on the type of the device. Information is received from the device identifying the type of device.
  • the altering is performed at a proxy server or at an origin server.
  • the device includes a device that is not configured to display the entire document at one time.
  • the device includes a personal digital assistance, a hand-held device, or a mobile phone.
  • the altering includes date compression, word abbreviation, or image suppression of images included in the original document.
  • the digital document includes a web page.
  • the method includes segmenting the digital document into subdocuments, and transmitting fewer than all of the segments in response to the request.
  • the invention features a method that includes maintaining a database that defines preferences associated with different client devices with respect to preferred alterations to be performed on full web pages requested by client devices that are not configured to display full web pages, the alterations making the documents more suitable for display on the client devices.
  • the invention features a method that includes obtaining from a client device information about preferences with respect to preferred alterations to be performed on full documents requested by a client device that is not configured to display the full documents, and associating the preferences with the client device in a database.
  • the invention features a method that includes creating content for web pages to be served to types of client devices that are not configured to display full web pages, and storing information about transformations that are to be made to the full web pages to make them suitable for display on the client devices.
  • the stored information associating each of the types of devices with transformations to be made to full web pages requested by that type of device.

  • segmentation feature first and then the transformation feature.
  • an Internet-enabled device 10 a WAP- enabled mobile phone, for example
  • an electronic document 12 e.g., a web page, an email, a text file, or a document in a proprietary format or markup language
  • the proxy server requests the document from an origin server 16 using the URL.
  • the origin server is a computer on the Internet responsible for the document.
  • the proxy server breaks (segments) the document into subdocuments.
  • the proxy server transmits the first of these subdocuments 1 to the client as a web page.
  • the segmenting of the document need not be done in the proxy server but can be done in other places in the network, as described later.
  • each of the subdocuments 20 delivered by the proxy server to the client contains hyperlinks 22, 24 to the next and previous (each where applicable) subdocuments in the series.
  • the hyperlinks are displayed to the user. If the user selects a forward-pointing (or backward-pointing) hyperlink from a subdocument, that request is transmitted to the proxy server, which responds with the next (or previous) subdocument.
  • the first step of the segmentation process is to determine (30) the maximum document size permissible by the client device. If the client-server communication adheres to the HTTP protocol standards as described in RFC2616 (R. Fielding et al, RFC 2616: Hypertext Transfer Protocol - HTTP/1.1. June, 1999.
  • the client advertises information about itself to the proxy server within the header information sent in the HTTP request.
  • the server can use, for instance, the value of the USER- AGENT field to determine the type of microbrowser installed on the client device and, from this information, determine the maximum document size by consulting a table listing the maximum document size for all known devices.
  • the next step of the segmentation process is to convert the input document into XML (32), a markup language whose tags imply a hierarchical tree structure on the document.
  • XML a markup language whose tags imply a hierarchical tree structure on the document.
  • FIG 4. An example of such a tree structure is shown in figure 4. Conversion to XML from many different source formats, including HTML, can be done using existing software packages.
  • the third step is to apply a procedure to divide (34) the XML tree 40 into segments, each of whose length is not greater than M.
  • the leaves 42 of the tree represent elements of the original document — text blocks, images, and so on.
  • Internal nodes 44 of the tree represent structural and markup information — markers denoting paragraphs, tables, hyperlinked text, regions of bold text, and so on.
  • leaf- clustering approach begins by placing each leaf in its own segment (as shown in figure 4) and then iteratively merging segments until there exists no adjacent pair of segments that should be merged.
  • Figure 5 shows the same tree after two merges have occurred, leaving merged segments 50, 52.
  • Each merging operation generates a new, modified tree, with one fewer segments.
  • Each step considers all adjacent pairs of segments, and merges the pair that is optimal according to a scoring function defined on candidate merges. An example scoring function is described below.
  • a lower score represents a more desirable merge.
  • the score of merging segments x and y is related to the following quantities: 1.
  • 100,
  • 150, and
  • 25, then a good scoring function causes score(x,z) ⁇ score(y,z) ⁇ score(x,y). The effect of this criterion, in practice, is to balance the sizes of the resulting partitions. 2.
  • segments x and y have a common parent z, then they comprise a more desirable merge than if they are related only through a grandparent (or more remote ancestor) node. That two segments are related only through a distant ancestor is less compelling evidence that the segments belong together than if they are related through a less distant ancestor. 3.
  • the node replication required by the merge Internal nodes may have to be replicated when converting segments into well-formed documents. Of course, in partitioning an original document into subdocuments, one would like to minimize redundancy in the resulting subdocuments.
  • Algorithm 1 Agglomerative segmentation of an XML document Input: D: XML document
  • the next step is to convert the segments of the final tree into individual, well-formed XML documents (36). Doing so may require replication of nodes. For instance, in Figure 5, merging leaves B and F has the effect of separating the siblings F and G. This means that when converting the first and second segments of the tree on the right into well- formed documents, each document must contain an instance of node C. In other words, node C is duplicated in the set of resulting subdocuments. The duplication disadvantage would have been more severe if nodes F and G were related not by a common parent, but by a common grandparent, because then both the parent and grandparent nodes would have to be replicated in both segments.
  • the proxy server After having computed a segmentation for the source document, the proxy server stores the individual subdocuments in a cache or database (38) to expedite future interaction with the user.
  • the request is forwarded to the proxy server, which responds (39) with the appropriate subdocument, now stored in its cache. If the proxy server is responsible for handling requests from many different clients, the proxy server maintains state (41) for each client to track which document the client is traversing and the constituent subdocuments of that document.
  • the proxy server can use the HTTP header information — this time to determine a unique identification (IP address, for example, or a phone number for a mobile phone) for the client device, and use this code as a key in its internal database, which associates a state with each user.
  • IP address for example, or a phone number for a mobile phone
  • the agglomerative segmentation algorithm (Algorithm 1, above) is performed only once per source document, at the time the user first requests the document. As the user traverses the subdocuments comprising the source document, the computational burden for the proxy server is minimal; all that is required is to deliver the appropriate, already-stored subdocument.
  • the documented can be segmented into subdocuments 104, 106, and 108 that represent parts of the main body of the document and subdocuments 110, 112 that represent portions of the form 102.
  • One of the subdocuments 106 contains an icon 114 that represents a link 116 to the form.
  • Other links 118, 120, and 122 permit navigation among the subdocuments as described earlier.
  • the content of the subdocuments that are served to the user devices can be automatically transformed in ways that reduce the amount of data that must be communicated and displayed without rendering the information represented by the data unusable.
  • Users can customize this automatic transformation of electronic documents by expressing their preferences about desired results of the transformation. Their preferences are stored for later use in automatic customized transformation of requested documents. For example, a user may wish to have words in original documents abbreviated when viewing the documents on a size-constrained display. Other users may find the abbreviation of words distracting and may be willing to accept the longer documents that result when abbreviations are not used. These preferences can be expressed and stored and then used to control the later transformation of actual documents.
  • the proxy server receives the request (18) and fetches (20) the document from the origin server.
  • the proxy computer After receiving the document from the origin server, the proxy computer consults (24) a database 26 of client preferences to determine the appropriate parameters for the transformation process for the device 8 for the user who is making the request. The proxy computer then applies (28) the transformations to the document to tailor it for transmission to (30) and rendering (32) on the client device.
  • the HTTP header in which the client device advertises information to the proxy server about itself can include two relevant pieces of information:
  • a unique identifier for the device For example, for wireless Internet devices equipped with a microbrowser distributed by Phone.com, the HTTP header variable X-UP- SUBNO is bound to a unique identifier for the device.
  • the device type For example, the HTTP header variable USER-AGENT is bound to a string that describes the type of browser software installed on the device.
  • the proxy computer When document transformation occurs, the proxy computer has already obtained the unique ID and can use it as a key to look up, in the database, a set of preferences associated with the user.
  • Figure 7 shows an example of rows in a fictitious database 24.
  • Each row 40 identifies a device by the device's telephone number.
  • the row associates user preferences (four different ones in the case of figure 7) with the identified device.
  • the telephone number e.g., of a mobile phone
  • the unique ID that serves as the key for the records in the database.
  • the proxy computer can use these values to guide its transformation process.
  • the inputs to the transformation process are a source document (in HTML, for instance) and a set of user preference values (one row in the database from figure 6)
  • document transformation includes a sequence of operations, such as date compression 52, word abbreviation 54, and image suppression 55, in converting an original document to a form more suitable for rendering on a small-display device.
  • the preferences for the target device are used to configure the transformation operations.
  • the client-specific preferences could indicate that word abbreviation should be suppressed, or that image suppression 55 should only be applied to images exceeding a specified size.
  • images can be subjected to other kinds of transformations to reduce their size. For example, images may be compressed, downsampled, or converted from color to black and white.
  • words may be abbreviated.
  • There are many strategies for compressing words such as truncating long words, abbreviating common suffices ("national” becomes “nat'l”), removing vowels or using a somewhat more sophisticated procedure like the Soundex algorithm (Margaret K. Odell and Robert C. Russell, United States Patents 1,261,167 (1918) and 1,435,663 (1922).).
  • the corresponding user-configurable parameter would be a Boolean value indicating whether the user wishes to enable or disable abbreviations. Enabling abbreviations reduces the length of the resulting document, but may also obfuscate the meaning of the document. Suppression of images
  • bitmapped images are likely to degrade in quality when rendered on low-resolution screens. For these reasons, users may control whether and which kinds of bitmapped images are rendered on their devices.
  • the corresponding user-configurable parameter in this case could be, for instance, a Boolean value (render or do not render) or a maximum acceptable size in pixels for the source image.
  • a transformation system can employ a natural language parser to detect and rewrite certain classes of strings into shorter forms. For instance, a parser could detect and rewrite dates into a shorter form, so that, for instance, "December 12, 1984” becomes “12/12/84", “February 4" becomes “2/4", and "The seventh of August” becomes “8/7".
  • the corresponding user-selectable parameter value could be a Boolean value (compress or do not compress), or it could take on one of three values: do not compress, compress into month/day/year format, or compress into day/month/year format.
  • a transformation system could parse and compress numeric quantities, so that (for instance) "seventeen” becomes “17” and “ten gigabytes” becomes “10GB.”
  • a user can enter and maintain preferences by visiting the proxy computer using the same small-display device he uses for Internet access.
  • the proxy computer could store a hypertext form 60 that users of small-display devices retrieve and fill in according to their preferences.
  • the proxy computer Upon receiving an HTTP request 62 from a client device, the proxy computer will automatically (using the HTTP protocol) obtain the unique identifier for the client device.
  • the proxy computer then transmits to the user a form 64 that contains a set of preferences. If the client device already has an associated entry in the database, the current value for each parameter can be displayed in the form; otherwise, a default value will be displayed.
  • the user may change parameters on this form as he sees fit and then submit the form back 66 to the proxy computer, which stores the updated values in the database in the record associated with that client device.
  • the user can visit the same URL using a conventional web browser on a 5 desktop or laptop computer.
  • the proxy computer will be unable to determine automatically from the HTTP header information which device to associate the preferences with.
  • the user must explicitly specify the unique identifier — hone number, for instance — of the device for which the user wishes to set the preferences.
  • Figure 10 shows an example of the form appearing on a conventional HTML-based desktop LO web browser.

  • the previous section described a method for end users to specify and store preferences, to be associated with a single device.
  • This section described a method for content creators to configure the transformation of documents delivered from their origin server. These two scenarios are not incompatible. Imagine that an end user requests a document X from an origin server Y. Imagine further that the end user has registered a set of preferences for his transformations, and that there exists on the origin server a separate set of preferences for documents delivered from that origin server. The document will be transformed first according to the preferences in the origin server, and then according to the end user' s preferences. In this scenario, the end user's preferences sometimes cannot be honored.
  • a user of a small-display device submits a request to the proxy computer for the preferences form document.
  • the form document is transmitted from the proxy computer to the device.
  • the user fills in his preferences and submits the filled-in form back to the proxy computer.

  • the client device stores this cookie as persistent state.
  • the device When a user of the client device subsequently requests a document from the proxy computer, the device also transmits to the proxy computer the cookie containing the stored preferences:
  • the proxy computer applies these preferences in transforming the requested document. If the client device did not transmit a cookie, either because the cookie expired or was erased, the proxy computer applies a default transformation.
  • wireless devices 50 and the "wired" Internet 53 typically occur through a gateway 52, which mediates between the wired and wireless worlds. For instance, a request for a document by a user of a WAP-capable device is transmitted to the wireless gateway, which forwards the request to the origin server 54 (on the Internet) responsible (according to the DNS protocol) for the requested document. If the requested document has been designed specifically for the client device and written in the markup language accepted by the device—sometimes HTML, but more often another markup language such as WML, HDML, or a proprietary language—content transformation isn't necessary. Because different wireless data devices have different capabilities, a content creator would have to create a separate version not only for each target markup language but also for every possible target device.
  • an automatic content transformation system 70 can automatically compress and reformat documents 72 into formats that are optimal for display on specific target devices. This leaves content creators free to concentrate on writing content rather than on retargeting content for a variety of target devices.
  • the content transformation system intercepts requests from non-traditional client devices, customizes the requested documents for display on the target device 78, and transmits the transformed documents 74 to the client.
  • the content transformation system employs user preferences 76 and device specifications 64 to guide the document transformation process. If the requested page 72 has been designed specifically for the client device making the request, content transformation isn't necessary. But designing documents for wireless devices is no simple matter. The document must be written in the markup language accepted by the device-sometimes HTML, but more often another markup language such as WML, HDML, or a proprietary language. Because the hundreds of different wireless data devices each have different capabilities 64 , a content creator faces the prospect of creating a separate version not only for each target markup language, but for every possible target device. The content provider also needs to understand how to detect the type of client device and create a document optimally formatted for that client.

  • a content transformation system intercepts requests from non- traditional client devices, customizes the requested document for display on the target device, and transmits the transformed document to the client.

  • the core content transformation component 81 can include the segmentation process described earlier.
  • the XML cache object 84 is where the per-user subdocuments are stored for the segmentation process.
  • Content transformation is a server-side technology and can naturally be deployed at various locations in the client-origin server channel, anywhere from the wireless gateway to the origin server that holds the original content.

  • the bottom of each subdocument rendered on the target device can contain a graphical status bar showing where the subdocument lies in the set of subdocuments comprising the original document.
  • ooxoooo could mean "this is the third of seven subdocuments".
  • each of the o's in this status bar could be hyperlinked to that subdocument, enabling the user to randomly access different subdocuments in the document. This can be more efficient than proceeding subdocument by subdocument in order.
