Abstract

Elements existing in data are detected, among which an existing context reference detects elements. A piece of resource information is assigned to one or more of the detected elements on the basis of a detected context reference and linked to at least one of the detected elements. A selection of data is made. Elements existing in the selection are detected.

Description

The presented invention relates to methods and systems for linking Resource information with elements in data to facilitate and improve navigation and research in computer-based data, data networks and network-based data banks, especially data networks and database systems with a graphical user interface and especially navigating and researching on the Internet or the World Wide Web in documents, databases, catalogs and information services accessible there.

Furthermore, the invention relates to methods and systems for analysis and modification cation of documents with the aim of closer linking of the content resources.

In particular, this concerns the identification of words / word groups in documents and creating hyperlinks. More particularly, this concerns the identification of Words / word groups using a locally stored, expandable database and that Creation of hyperlinks, which information about contextual connections of the contain identified words and / or phrases.

Due to the storage capacities of storage media for data processing available today but also due to the now widespread computer network works it is possible for users of electronic data processing systems, both on large local databases as well as on almost unlimited resources in computers access networks.

Local networks can range from 2 to several 1000 data processing systems sen. High bandwidth, low error rate and the usual exclusion local networks make useful tools such. B. for education and Industry. The connection of such local networks and the possibility for single, d. H. also create private computer systems to join this network  the seemingly unlimited possibilities, such as those that exist today are known under the name Internet.

With the increasing amount of accessible information arises increasingly the problem of making them quickly and reliably available. This is ins A problem that should not be underestimated, especially on the Internet, since information is there today predominantly in the form of text documents, the majority of which are hyper Use text markup language (HTML). For this reason, the example of Internet briefly the problems that are currently with the information procurement in large databases, especially when the information is connected predominantly in the form of text documents.

HTML is the key to so-called hypermedia, i.e. H. linking anywhere a document with any resources in the entire network using hyperlinks. Nice Before the invention of hyperlinks, cross references in documents were e.g. B. in the form of Known as footnotes, annotations or as a source. In contrast to e.g. B. A source link in a book allows a hyperlink to be a much more direct one Access to information associated with the appropriate place in the text. On Hyperlink is usually in one place on an optical display dium representable document arranged from which after activation, z. B. by a Mouse click, jump to another representation of this or any other Document or even to non-representable resources. Res not shown sources can e.g. B. Requires a download files. The concept of hyper On the left, authors and users can find further topic-related information mations to offer. The disadvantage of the current concept of hyperlinks is that the The quantity and quality of the inserted hyperlinks is the sole responsibility of the Web author. If the author of a document or a document-producing Program does not consider links necessary or does not provide them, for example because they are created links appears to be time-consuming, no links are set.

To give the user, the "surfer", access the information they want on the Internet facilitate, exist on the one hand so-called catalogs such as z. B. offered by Yahoo become so-called search engines.  

Web catalogs arrange and organize the web pages according to thematic areas. The Topics are arranged alphabetically and hierarchically. Most offer kata log in to an integrated search engine.

For the web catalogs, so-called catalog editors on the World Wide Web (WWW) existing documents viewed and, provided they meet the internal criteria of the respective Web catalog provider correspond to one of the categories available at the provider taken. The documents that can be accessed via a web catalog are organized, on the other hand, it is obvious that they by no means have a complete overview of enable the offer of information on a subject, since it is the catalog editors it is impossible to sift through all the documents available on a topic on the WWW. There is also the risk that documents from the catalog should not be underestimated editors are misclassified. In addition, the navigation or that costs Browsing through the time catalog categories and classifying a document into one certain category and the structure of the catalog as a whole is often only cumbersome understand.

Another way to help surfers find the information they want facilitate, are so-called search engines, as currently z. B. from AltaVista, Excite or Lycos are offered. Search engines are programs that have a Database, e.g. B. from the WWW, build an index and allow a surfer, to look in this index. The index is built up automatically using so-called Robots, also called "spiders" or "crawlers". Explore these programs the WWW to find a document and the associated hyperlinks. This information is then cataloged and used by the search engines made accessible.

In search engines, the abundance of so-called hits often makes the answer to one Search query useless. Many of the documents found contain those with the request certain words, but have nothing else to do with the desired topic. again Limiting the search terms suddenly takes time and carries the risk of moving away from the remove the desired term.  

Meta search engines allow simultaneous searches with multiple search engines. In principle, however, they exacerbate the problem of the unmanageable for the user Number of hits, since they are partly due to the imperfection of the search engines queried add.

Compared to a web catalog, a robotic search engine contains through the Automation of information gathering a much larger number - for that topic searched but often irrelevant - documents. On the research page, the lower number of documents on a specific topic, via a web catalog are available, the advantage that the quality of the existing documents as a rule is significantly better than the one that is found via automated search engines the. On the other hand, there is a risk with web catalogs that relevant information not to be offered at all, since corresponding documents are not or wrong are cataloged.

Both approaches also have the disadvantage of being more human because of their ambiguity Expressions, the different languages and incorrect page descriptions are often erroneous deliver vante results.

In order to improve the possibilities of finding information on the WWW, various approaches are proposed or offered:

• - Combining the search engine and catalog approaches, d. H. additional offer one Search engine for web catalogs;
• - attempt to classify documents using linguistic program algorithms, to be statistically evaluated and classified in the Universal Decimal Classification (UDK) to make them accessible in an automatically generated web catalog;
• - Standardization of the document content description, e.g. B. by the Dublin Core Metadata element set. The use of standardized meta information for The content description of documents is the sole responsibility of the respective author and is likely to take hold slowly;  
• - Automatic index creation via a local offer enables local and thus contextual search engines. A typical application is the search function within a homepage.
• - Finally, modern Internet browsers offer the option of entering in the address bar which usually just entered the URL (Uniform Resource Locator) of a homepage will enter any word. If a string complete If the result is a valid web address, this is jumped to, otherwise the search engine preset by the manufacturer of the browser. This procedure however, only makes it easier for inexperienced surfers to find information, But does not change the disadvantages of automated search engines described above NEN.

Finding information on the WWW currently has the disadvantage that it is sometimes difficult to get information on a particular topic through the user web catalogs and / or search engines. You have a document found that contains information on a topic you are looking for is "continue surfing" in generally severely restricted if not impossible, that only quantitatively or insufficient quality hyperlinks are present in the document found. The The number and quality of the hyperlinks in a document is, as already mentioned above described, currently depends on the web author of each HTML document. comparison But there are also real problems if you look in other databases certain information or other content.

The object of the present invention is therefore a better method and a better one To provide a device for researching databases. In particular is it object of the present invention, a better system for navigation and research to be made available in data networks.

In terms of process engineering, these objects of the invention are achieved by claims 1 and 20, device technology by claims 23 and 3, by the computer pro Gram product according to claim 21 and by the data carrier according to claim 22.  

According to the inventive method for linking resource information with Elements in data that are in a form that can be processed by data processing systems, existing elements are determined in the data, existing between the elements whose context reference is determined, a resource specification for at least one of the determined Elements are assigned based on the determined context reference and the resource c linked with at least one of the determined elements.

The invention also provides a method for linking resources provided with items in data that were processed in data processing systems editable form, with a selection selected from the data in the selection existing elements are determined, a resource specification for at least one of the ascertains assigned elements and the resource specification with the at least one of the elements are linked.

The device according to the invention for linking resource information with elements in data that are available in a form that can be processed by data processing systems a device for determining elements present in the data, a device to determine the contextual relation between the elements, an on direction for assigning a resource specification to at least one of the determined el elements based on the determined context reference and a facility for ver link the resource information with the at least one of the determined elements.

According to the invention, a device for linking resource information with Elements can be provided in data that are processable for data processing systems Form present, which is a device for selecting a selection from the data, a Means for determining elements present in the selection, a facility to assign a resource specification to at least one of the determined elements and a device for linking the resource information with the at least one of the contains determined elements.

The invention is explained in more detail below using an exemplary embodiment. Even if here - mainly for the sake of illustration - mainly the application the invention is described in the field of the Internet, it is the average subject But it is readily apparent that the invention applies to all data in for data processing plants are available in a form that can be processed.

The word information service used above does not adequately describe the total of what is available on the WWW. On the one hand, the WWW is different their information, but on the other hand also provides the entry gate in most cases to the offers of the other services outlined above.

Through the method according to the invention presented here, the device according to the invention device and the computer program product according to the invention, it is possible to link automatically create documents and thus the range of such links Extensions in any documents significantly and thus the navigation in the net easier, more dynamic and more effective. By adding additional ver Links in documents make the offer of such links essential expands and can better the existing information and service offer can be achieved.

Almost every conceivable piece of information reaches countless users on the Internet around the world and is gradually replacing conventional modes of information transmission like mail, phone and even television. New opportunities and types of information offers  and information access opportunities are created by the new and next Development of network-compatible devices such as cell phones, eBooks. In the future but z. B. even household appliances, such as refrigerators, with network skills are offered.

The offer of the WWW is no longer limited to pure information. So Interactive websites enable the publication of reactions to the content various providers, without the need for news groups. Through use and that Offering webcams and animations as well as using all possibilities of the A wide range of entertainment is available in multimedia.

Any network that uses the Internet protocol suite (IP, TCP, UDAP, ICMP). The data transfer protocol of the Internet is missing Delivery guarantee or flow control of the data packets marked. This lack At the same time, the reliability of the Internet also enables its tremendous flexibility lity, which is one of the reasons for its popularity.

The following services are essentially offered on the Internet:

• - FTP (File Transfer Protocol): FTP is a data transfer protocol that is used for the Trans port of files over the Internet without their graphical representation. FTP is not really an information system.
• - Telnet: With this Internet service you can work on computers in the network as if your own keyboard and monitor connected directly to the remote computer would be. At the same time, Telnet is the name of the data transfer used for this transfer protocol.
• - Usenet Newsgroups: Newsgroups are discussion forums on the Internet. With special Software anyone can participate in the newsgroups, i. H. even articles in the Publish news groups and get answers to your own questions here. The here The hierarchical order of this service makes it possible to find a group.
• - IRC (Internet Relay Chat): A multi-user communication system by means of which users chat in so-called "channels" in groups or individually  can. Similar to Usenet newsgroups, the channels are often in thematic conferences divided up.
• - Email: This is the electronic mail on the Internet. This allows data of all types, such as z. B. Text files, language information and computer programs are transmitted.
• - Gopher: This is a worldwide information system on the Internet with a hierarchy structure. Loses because of the proliferation of the World Wide Web (WWW) Gopher is currently becoming more and more important.
• - World Wide Web (WWW): Worldwide, locally distributed and hypertext-based Information service on the Internet. The HTTP protocol is used on the WWW enables information to be sent as HTML documents (HTML = HyperText Markup Language). The exact specification is from the WWW Consortium in the RFC 2616 (Hypertext Transfer Protocol - HTTP / 1.1., R. Fielding / UC Irvine, J. Gettys / Compaq / W3C, J. Mogul / Compaq, H. Frystyk / W3C / MIT, L. Masinter / Xerox, P. Leach / Microsoft, T. Berners-Lee, W3C / MIT, June 1999). As part of the Designing HTTP documents can make these documents particularly clear and often presented graphically.

The following is the manufacturer of the HTML documents, associated resource cen and the links called "web author". The reader or recipient of this Documents is referred to as a "surfer". These terms for users of the World Wide web has become generally accepted.

The WWW can be understood as a subnet of the Internet. The WWW service In addition to retrieving documents from the Internet, it also enables access on databases with their own parameters. To use the WWW To use the service, you need special software, the Internet browser or web browser. The standards valid for the web are from World Wide Web Consortium (W3C) created.

The HTTP protocol is fully described in RFC 2616, so that it is only briefly shown how a client receives a hypertext document:
If a surfer wants to request a hypertext document, a client establishes the connection to the server (e.g. using the TCP / IP protocol). The host name and port number are used. If no specific port number is specified, port number 80 is always accepted and used for http. The client's request to the server consists of at least one line of ASCII characters, starting with the string "GET", followed by a space and the address (URI) of the document. The answer to a "GET" request consists of an ASCII-coded byte stream, the lines of which are terminated at least with LF characters (line feeds). This ASCII text describes the hypertext document in HTML format. After the server has transferred the entire document, the server closes the connection.

If the client does not make a request, but is to transfer data to the server, instead of "GET" the method "PUT" if a document is changed on the server or "POST" if a document is saved on the server again should be used.

The document addresses are from W3C in RFC 2396 ("Uniform Resource Identi fiers (URI): Generic Syntax "by T. Berners-Lee / MIT / LC, R. Fielding / U. C. Irvine, L. Masinter / Xerox Corporation, August 1998). URI's are divided into Uniform Resource Locators (URL, RFC 1736; "Functional Recommendations for Internet Resource Locators ", J. Kunze / IS, U. C. Berkeley, February 1995) and Uni form Resource Names (URN, RFC 1737, "Functional Requirements for Uniform Resource Names ", K. Sollins / MIT / LCS, L. Masinter / Xerox Corporation, December 1994).

URLs are formed for the http protocol according to the following syntax:
http: // hostname [: port] / path [? search]
where the square brackets stand for optional components.

The "path" element can also contain the name of a file. Is not this the case, a standard file name is assumed. One specified in this element The file can also be a program that can be executed on the web server then the actual HTML response is generated. The "search" element can have several Terms separated by plus signs. These terms can also be term pairs separated by equal signs. With the inven described here URLs that appear in the "path" part are preferably used name the executable program and the meh in the "search" part contain more pairs of terms.

As already described, the http protocol enables the transmission of documents elements as hypertext / hypermedia in HTML format. HTML documents contain in addition to the actual text further information, which is inserted in tags are closed.

The first group of tags, which characterize the HTML format, determines the reason structure of the document. These tags indicate the beginning and end of the HTML code and divide the document into head ("head"; the title and other information) and body (the content of the document).

Example of an HTML framework:
<Html <
<Head << title <Three points Document </ title << / head <
<body <. , , </ Body <
</ Html <

A group of tags, called meta tags, are usually found at the top of the Document. They contain information about the respective document itself. This can be, for example, information about the author, copyright and so on. Also Information about the use of the document can be included here, for example  Synopsis in the form of keywords.

Example for a meta tag:
<meta name = "keywords" content = "Internet, HTML"<

Another group of tags contains information about additional content to be displayed, such as graphics and multimedia. These are not directly in the document saved. Only a URL to the corresponding file is given. It can a completely different place on the net serve as a source than for the actual documentary ment.

Examples of tags for inserting an image:
<img src = "/meinbild.gif"<
<img src = "http://www.andererserver.de/bilder/bild001.gif"<

The largest group of tags are formatting tags. These refer to the Dar position and positioning of the content. This affects both text and the other elements of the document that are not stored in the file.

Example of a formatting tag:
<center <. , , </ Center <

The anchor tags represent a special group of tags. Here is an element of the document, usually text or a graphic, with a resource on the web or one linked elsewhere (anchor) in the same or another document.

Example of a tag that defines an anchor:
<a name = "anchor1"<1) HTML </ a <
and the anchor tag that points to it
<a href = "# anchor1"<to 1 .: HTML </ a <

Example of an anchor tag to another URL:
<a href = http: //www.hyperjoint.com/ <. , , </ A <

Such an anchor tag represents a hyperlink. A hyperlink can do so in the document be formatted so that it is visible to the surfer when viewing the document.

Hyperlinks can be created manually with an editor. Before any Text section in the body of an HTML document becomes <a href =. , , <inserted after the section </ a <. This process is simplified with an HTML editor: The Text section is marked and after a command, such as "<Insert In a dialog box, only the URL and possibly other ones will be displayed Attributes specified. The HTML editor then creates <a href = independently. , , <and </ A <. Hyperlinks can be in a hypertext document at any time point, i.e. also after creation, can be created and inserted. This can be done like any editor or HTML editor can be used.

An automated program process can also include the insertion of hyperlinks carry out certain sections of text to be determined by the process itself. The latter is used in the invention presented here.

A user of the program system based on the invention uses, for example a computer program called a "web browser" or "browser" to display hypertext To look at documents. Web browsers exist as computer programs for the ver various operating systems. They are used to present data in different formats put. You can transfer this data both via a network connection and from loka len media received. Their main feature is the ability to translate documents into HTML Display format. It is not necessary that all elements of a document from the come from the same source. Darstel excludes the ability to display HTML documents and use of hyperlinks. A hyperlink can lead to a document which in turn contains hyperlinks. Continued use of hyperlinks to Jump from one place in a document to another place in the same or  another document or any resource is referred to as "surfing" net.

Web browsers can localize and display data from various Internet services. These include FTP, Telnet, Gopher, Usenet, email and the World Wide Web. The The concept of hypertext, which is fundamental to the invention, currently mainly comes from WWW for use. This concept is also used by modern email programs supports, so that the invention in addition to the other uses also on this use of the internet.

It is conceivable that a different display method comparable to a web browser dium is used, for example a braille display or an acoustic output. at In the presence of HTML files, these output media take advantage of the fact that the HTML format is just a description of the document, the exact order setting is left to the medium of representation.

With the aid of the method and program system according to the invention, it is possible to do any edit this document as a file regardless of its format File - u. U. after a possible temporary storage - to be presented in a format, that supports the concept of hypertext. So it would be possible, for example, to clean To process ASCII text using the method and program system according to the invention prepare to convert into an HTML file and display it through a browser to let.

If text is in a format that doesn't support the concept of hypertext, which is suitable for generating a jump target can deviate from the one described here Embodiment of the invention out of this format by the program system a jump to a network resource can be initiated. The user marks z. B. Text displayed on a screen and resolves in a suitable manner, e.g. B. by a Context menu or a hotkey from a program process using a web browser starts.

It is also a great advantage if a search engine or other data source Infor receives information about the context from which a request is made. this makes possible  in any case a better choice among the possible hits. The limitation of The number of keywords is balanced by their representation in the respective context.

The final behavior of the program process is from the user, from web authors and / or providers of a corresponding service using the invention largely controllable, in particular the elements, the context assignment and / or the el resource assignments can be individually set. This has the advantage that the user or a third party the inventive method and the fiction can adapt the device to specific needs or developments. So can For example, the user can also prevent the process if the inventor benefits according to the invention do not want to make use of.

Through program processes that preferably run locally at the user, at for example documents from the Internet using a locally stored keyword, Categories and rules database analyzed and from the respective analyzed text context during the transmission of hyperlinks in the web documents generated. These are used for contextual navigation or research.

The user of the computer program product according to the invention typically requests this usually use any web resource with a web browser. He can do this in the Browser address line a document end address in the form of a URL (Uniform Resource Locators) or an IP address (IP = Internet Protocol), it can be a Hyper Use link or use already saved URL or IP addresses. Finally there is a possibility that when starting the internet browser a preset web page is called automatically.

If the requested resource is a webpage, the web browser directs this request to a local web server belonging to the program system. If it is a different resource, for example an FTP download, the Web browser the request to the web server of the user's provider.

A local web server is also called a proxy server. The proxy server routes the Request to the web server of the user's provider, which res requests resources on the Internet.  

The proxy server receives the content of the requested resources sequentially. Case it is HTML files, the proxy server transfers them sequentially to the Pro Analysis module belonging to the gram system. All other files, for example one Image files belonging to the website are forwarded directly to the browser for display passes.

The analysis module determines all the words in the HTML file that are necessary for the automatic Conversion into hyperlinks is an option. These words are the database mo dul, which they match according to words / phrases in one checked local database and in case of a match assigned to the term Returns information. The database belongs to the program system and is operated by the database management module created and maintained. Text areas by the Bear processing are excluded or already contain hyperlinks, will be analyzed by the analysis dul ignored. The parts of the file that have already been analyzed are also checked during the check and possibly previously analyzed data are used to find the matching data Words / groups of words to create a contextual reference.

All matching words / phrases are converted to hyperlinks. To they are enclosed in HTML anchor tags. They contain a URL for reference from a provider that provides further information on the words / groups of words found offers catalogs or services, as well as information about the respective word and Information about the contextual reference. Alternatively, direct links can also be created those that are directly related to the words / groups of words found refer to the resource that exists in the URL of the database.

The analysis module returns the changed HTML code to the proxy server, which forwards it to the browser for display. The user faces one of the requested resource identical page, which ent a strongly increased number of links holds.

The user can influence the method according to the invention with a control module sen.  

In the event that the method according to the invention is used to automatically generate hyperlinks from the respective analyzed text context during the transmission in web documents, a system of computer programs or program modules is required which does the following:
It must be able to switch to the normal transmission path of a web document and it must be able to analyze the document and change it accordingly, ie automatically insert hyperlinks.

To switch to the normal transmission path of a web document, you have to a program or module first learns that a document has been requested, and which it is. For this, in the embodiment described here, the Invention of the web browser or the requesting display medium with the Send a request to this program instead of making a request to a web server. This is achieved by installing a local virtual web server. This will then the browser / display medium as the (http) proxy server to be sent ben.

A server must have or be able to create something that the client does not have or can do something the client cannot (e.g. do a certain calculation), and he must be able to serve the client. The client must be able to access the server to the desired information or the desired result receive. To do this, the client and server must use a common protocol.

There can be a direct data transmission connection between the client and the server, such as via a so-called null modem cable, via a network connection work cards and network cables or via a modem connection via a Telephone line.

For the user of the Internet there is only a direct data transmission connection its internet access provider. This runs a web server, which the requests of the Forwards the browser of the internet user to the web server that requested the Provides information / resources.  

A proxy server is a combination of a server and a client, with the Ser ver the main component for the requesting program (hereinafter "the original Client "). Its server component takes over from the original client Request a specific resource. He acts for this original one Client as a full server. However, he is not able to do the requested res to provide source. He only forwards the request to his own client Component further, which now appears as a client to the actual web server and makes the request. The client component of the proxy server now receives the answer to the request from the web server. It can, but does not have to, edit the answer before it forwards them to the server component of the proxy server, which in turn sends them to the original client in response to their request.

According to the local virtual server, the proxy server, is realized by Sockets are defined and implemented which are the server and client components of the Describe proxy servers. Sockets describe the end points of the data transmission network bond between programs. Sockets are in higher programming languages than Defines objects that contain properties and methods that are suitable for data initiate or accept transmission links between programs and to be carried out after it has come about. They can be found under most operating systems men can be implemented.

For example, in the Java package java.net, the objects are java.net.Socket and java.net.ServerSocket contain the object TAbstractSocket in the Delphi unit Scktcomp and the Tclient Socket and TserverSocket objects are derived from this. According to the invention regardless of the programming language used, both a server socket as well as a client socket to use. It is important that the server Socket must be able to accept and accept multiple connections simultaneously to edit. This happens normally and also according to the invention, by pro akzep connection, a separate program process, a so-called thread, is started.

This procedure enables the user to have multiple instances of his Web browser or display medium can start at the same time without this  hinder each other. For example, Delphi must have the ServerType property from TserverSocket to stThreadBlocking.

The ServerSocket must also have a local IP address and a port number which the web browser or the display medium is to be used Use proxy address, the server is located on this port of this local address verSocket at program start or after activation in "Listen" mode, that is, it accepts all requests requested by the web browser / presentation medium.

A request contains various information about the requested resource, the expected one Answer, the inquiring medium, the language, the operating system and more. The used ServerSocket, which, for example, a descendant con when implemented in Delphi TserverSocket is, in Java it would be java.net.ServerSocket, for example Request in a suitable data type. This is similar to Delphi's TwebRequest, or derived from TwebRequest (e.g. TEinWebRe quest). Every request from an original client causes the ServerSocket to starts a new thread that processes this request (if ServerType on stThreadBloc king is set). In this thread, a socket is now initiated for a client ized, for example, a descendant of TclientSocket (in Java from java.net.Socket). Corresponding objects exist in all higher programming languages chen.

The request is then transferred to the client socket (e.g. as TEinWebRequest), then it connects to the server of the provider specified by the operating system or, if this was already established, it uses the specified connection to the Forward the request to the web server. When implemented in Delphi, for example a stream is initiated in the thread environment of the client socket, via its write Method the request (TEinWebRequest) is passed. The client then expects Socket the response from the web server, which it sequentially in blocks of z. B. a kilo accepts byte. This is done using the read method of the stream.

According to the http protocol, the answer consists of two sections, one Header and a body section. These are in the client's appropriate fields Socket taken over.  

The header is immediately passed on to the higher-level ServerSocket.

The body section is sequentially sent in blocks to the program module passed on. The size of the blocks depends on the speed of the data transmission connection to the web server dependent. The faster this connection is the larger blocks can be transferred to the analysis module. Aim of handover in Blocks is the processing of the document at the same time as its transmission.

It must be ensured that at the interfaces of the blocks passed no connections are lost. The analysis module does not start until the second passed block with the analysis and includes the previous block. It returns the changed data sequentially. The returned from the analysis module The client socket immediately transfers data to the server socket.

The server socket immediately transfers all data received from the client socket to the original clients, that is, usually to the web browser for display.

The document received and displayed by the web browser corresponds to the original Requested, with the exception of the hyperlinks inserted by the analysis module.

The analysis module determines the words / word groups and to be converted into hyperlinks includes these in anchor tags.

As already described, the analysis module receives the data to be processed from the proxy server in the form of blocks of a byte stream. It is a very small one Document, or a very fast connection to the server, can also be a single block contain the entire document.

The text described by the bytes of the transmission stream is used by the analysis module examined for the beginning of the <body <area of the document. Only within the tags <body <. , , , </ body <further examinations are carried out. Even existing hyperlinks, i.e. text areas within <a href. , , <. , , </ a <tags ignored.

According to the invention, certain elements can be assigned and linked with Resource details are excluded. On the one hand, this has the advantage that the number  the links are reduced and secondly unwanted links be avoided. Control which elements are excluded from an assignment can either be by controls within the data or by controls elements outside of the data. Controls within the data can For example, certain control characters can be a control outside of the data for example, a blacklist that contains the elements to be excluded from an assignment contains.

For example, since the markup language HTML also defines your own meta According to the invention, tags can allow areas of can be excluded from editing by inserting them into such own meta tags be closed. For this, the provider or providers of the Ver driving and agreeing the web authors on a specific meta tag.

For example, a tag pair to control or suppress automatic hyperlink generation within the <body <area could be:
<noautolinks <. , , </ Noautolinks <

It would also be possible to define a new attribute for existing tags
<p autolinks = no <. , , </ P <
to influence an area or by means of

In the areas not excluded from the analysis are described in one here NEN embodiment of the invention then searched for words and / or groups of words. A "word" here is a sequence of "characters" that belong to the group of letters ("a... Z", "A... Z") or belong to the group of digits ("0... 9") and those of limitation charac ters are included (e.g. spaces, punctuation marks). Others of limitation scha Character strings that are included are not considered a "word" in the present case.

The term "element of data" encompasses any form of data, through any Predeterminable criteria can be distinguished from other data. In the top Example described are words and / or groups of words by Limiting characters are included and can thus be recognized as an element. On  Elements from a graphics file can be determined by their shape, for example. Should for example a word and / or a group of words from a graphic file as an element can be recorded by selecting the graphic file or a section thereof and subsequent optical character recognition.

For each recognizable word, a comparison is made as to whether it is in a pro database belonging to the gram system is included. This database that the requests processing module ("database module") and the module organizing the database ("Database management") are described below.

If the word is contained in the database, the database module provides this information (as a Boolean "true") back.

If the word was identified as the beginning of a phrase in the database, the database module also returns this phrase, so that the following word or according to the length of the phrase contained in the database, the following Words can be checked for belonging to the phrase.

For each word / phrase identified in this way, the database mo dul Information about possible context assignments of the relevant word / s returned relevant phrase. On the processing and application of the Context information is discussed in more detail below.

The analysis module now adds an anchor tag in front of the identified word / phrase a, consisting of the characters <a href =. , , <. The anchor tag is identified after the th word / phrase by inserting the characters </ a <.

In one embodiment of the invention, the specified reference URL contains the Address of a provider of information, resources or services, which together stand with the identified word / phrase.

The reference also includes pairs of terms with information about the word / the Phrase, about the context assignment of this word, as well as about so far in the document context assignments. Optionally, further information can be programmed scher kind, for example about the program / database version used and / or  legal type, for example registration status may be included. Can also be optional Information about the user, for example the exact location may be included.

Typically, on the server of the provider, the inventive method uses a program that evaluates the transmitted information generated an answer page.

Furthermore, the anchor tag can have attributes for the display of the generated hyperlink included, for example regarding the color. The values of these attributes will correspond corresponding local settings that are created in the control module of the program system Users can be made. The control module is described below.

An example of an inserted anchor tag:
The phrase "RFC 1736" was found in an article about the http protocol and is to be converted into a hyperlink.
<a href = "http://www.einträger.com/cgi-bin/
speciallinks.cgi? group = rfc% 201736 +
context = url + global context = http + ver = 01004 + reg = 12345678 "
style = "font: bold italic; font-size: 24pt; color: black"<

Information about the context can also be encoded. At the provider "einanbie ter.com "would use a program called" speciallinks.cgi "after using this link started, which creates an HTML document. This document can in turn Contain hyperlinks, for example to the W3C, to the start of the RFC tree and to the RFC's 1736-1738.

In a further embodiment of the invention, the reference URL of the generated Hyperlinks directly to a resource anywhere in the network point. This URL would then be provided by the database engine. As answer of the database module would in this case give every possible context assignment a URL String added. The analysis module would be the best possible as described below Select the assignment and the associated URL and the formatting attributes in the Insert anchor tag.

Example of an inserted anchor tag with a direct link:
<a href = "http://www.ietf.org/rfc/rfc1736.txt"
style = "font: bold italic; font-size: 24pt; color: black"<

Both types of hyperlinks, those serving the request and the direct links, can can be created side by side within a document.

Each processed block is sent to the proxy server, or more precisely to its client socket returned.

In one embodiment of the invention, all modules of the program system are on stored in the user's computer system and also run there. So it is possible without a connection to a computer network, e.g. B. an HTML document to edit.

In this embodiment of the invention, the content of the user of the control module selected document described below from the control module passed directly to the analysis module. In this case there is no processing in blocks necessary. After processing, the analysis module sends the document to the control module dul back, which save this directly or as a copy or on a display medium can be made visible.

In a further embodiment of the invention, the method can be carried out in one Web browser integrated program or tool can be started. Such a work Stuff is called a plug-in. This plug-in could already be in the web browser displayed but not edited document using the "PUT" method and a tem pass the local local URL to the proxy server, which processes it from the analysis module can be processed and the modified document sent back to the browser.

Hyperlinks can not only be created in HTML documents, but also in other documents, provided they support the hypertext concept. In this case no anchor tags are inserted, but those for the respective document format specified commands. For some formats, an entry in an anchor List necessary. In any case, the specification of a reference and formatting tanga ben made.  

After linking at least one element to the Resource specification the data is reproduced, the at least one element, that is linked to the resource specification is reproduced differently than the rest Elements. If, for example, the reproduction is optical, this can be at least one affected element z. B. shown in a different color or font than is the case with the other elements.

In a further possible embodiment of the invention, the invention Procedures can be started by a tool that is in a suitable one, the Hyper text concept supporting application is integrated. Such a tool is called Plug-in, referred to as add-on in some applications. Ver come into question here various applications, especially word processing programs. The plug-in or add One could send the content of a document already loaded in the application to the Ana Pass lysis module, which it processes and with automatically generated hyperlinks returns. The plug-in / add-on either of the loaded document creates a copy or replaces the content of the already loaded document.

According to a further embodiment of the invention, a jump can also be made a web resource can be triggered by a web browser through the program system is started. This requires data that can be recorded as text in any application be marked. It is not only the selection z. B. by a suitable to understand netes pointing device, but it can also "marking" z. B. even then occur when the cursor of a pointing device during a predetermined period of time the optically reproduced data lingers. With a suitable command, for example game using the operating system's context menu or with the help of a preset ten key combination (hotkey), the user can cause the control module to read out marked data and the analysis module to create a hyperlink reference to hand over to renz. If the marked data is e.g. B. from a section a graphic file, the "reading" of the data takes place with the help of OCR (optical character recognition, optical character recognition).

If, for example, due to the shortness of a screen output that can be recorded as text Contextual reference between elements cannot be established, can be based on the context previously edited  Data can be accessed. Under certain circumstances, however, this can lead to the out of several possible context assignments is not the right one can be determined. In this case, the standard assignment must be made. The The control module then starts the web browser and transfers it to the analysis module identified resource (s). It can advantageously also be provided that the user from several resource information that, for example, to an element are available that can select the most sensible for him at the moment.

The determination of contextual references represents a not insignificant advantage of the Erfin compared to the prior art. However, it is possible to the Determination of contextual references either on a case-by-case basis or not at all if a context reference cannot be determined or cannot be determined with certainty.

The context mapping information returned by the database engine is in a temporary list that is only valid for one data record at a time. there this list already is, possibly from several possible context assignments For a word, it best matches the assignments already in the list send selected. As the size of the list grows, there are more and more precise ones Assignments. If this selection is not possible, the standard assignment is made men. This is either context-neutral or corresponds to the most common in language use Assignment.

At the end of editing a record, the list of context assignments summarized. To do this, it is determined which assignment occurs most frequently. Different assignments occur in the same or at least comparable high frequency, the summary can also contain several terms include. These summarized assignment terms are in a permanent List saved. This makes it possible, especially when using the inventive Processes the assignments earlier on the first elements of new data data used as a guide for better allocation selection. this The approach is based on the idea that, for example, very often larger ones on the WWW Documents (documents in the traditional sense, writings) in several web documents elements are divided, which then allow the same context assignments. Also a  Users rarely switch from one document to the next abruptly. is if this is the case, new context assignments will also appear in principle. Becomes If this is recognized in the comparison, the permanent list is not used.

The mappings returned by the database engine to each entry found consist of a category code. They indicate the classification (or meh such classifications) of the entry in a classification system. This system in the embodiment described here is based on category structure, preferably a strictly hierarchical hexadecimal category structure.

Is used for the determination according to the embodiment of the invention described here of a contextual reference uses a hexadecimal category system, this has the advantage that an optimal use of the available memory is possible.

For example, all possible contexts are assigned to one of 16 categories orders, which in turn are divided into 16 subcategories and so on. Doing so When subdividing, the order of the subcategories should be as similar as possible placed. For each hierarchy level of the classification, half a byte is allocated needed. With a six-level hierarchy that could be represented with a code number of 3 bytes more than 16 million categories can already be created. If the most significant Category (in a conceivable implementation) the language of the term to be classified in the remaining five-level hierarchy, you can still use 1 Form a million different categories.

The Universal Decimal Classification (UDC), a comparable classification system for the entirety of all recorded knowledge currently includes (1997 version) only approx. 220,000 categories, whereby a medium edition uses only 60,000 categories.

Each term can be a category of any level or several different Categories can be assigned at any level. The latter is for example with one Term like "Note" is the case that both the category "Art" or the subcategory "Music" can also be assigned to the category "Politics" or the subcategory "Diplomacy", as well as other assignments ("Education, rating systems",...).  

A context assignment within an existing document is provided by a simple Chen subtractive comparison of the classification code achieved: Are in one document the terms "piano" or "Bach" have already been identified Category "Art" and here even the subcategory "Music" is assigned for the Term "grade" also adopted this classification. The classi fiction code of the term to be examined digit by digit with those in a list stored codes of the terms previously examined in the document compared. ever later in the code there is a deviation, the more similar the terms are. lower Similarity exists even if an occurring deviation is small, because the Order of categories based on similarity has been set.

The same procedure can be used to assign a context within a group of documents if the individual code lists of these documents are whole or are available as a summary.

As can be seen from the above example of the term "note", it only has to be in one Depth of the hierarchy are examined, in which the different allocation possibilities differentiate the terms of the term from each other. Here it would already be in the top one Level of the category, that is the case in the first digit of the classification code.

The database module replies to those made by the analysis module to the database Requests. The return takes the form of a Boolean answer as to whether the word / the Phrase is included at all, as well as a suitable data record in this Case (a "true" of the answer) contains additional information.

To carry out the query, the query passed by the analysis module is first Word standardized. As described above, such a word consists of a sequence of Characters belonging to the group of letters ("a.. .Z", "A.. .Z") or to the group of Zif far ("0. .. .9") belong. Since this is multiple spellings for a word (for "http" for example, too "Http" and "HTTP"), the entire word is converted to lowercase.

According to one embodiment of the invention, it is possible to transform into a carry out your own character set, for example only lowercase letters and numbers contains. If the terms in the database are also encoded in this character set,  this enables a significant reduction in the storage space requirements of the database. Four characters would only need one byte.

A database query is now carried out for the word thus transformed. Doing so the position of the determined element within the category structure of the database determined and the resource corresponding to the position with the respective Ele ment linked.

For this purpose, in one embodiment, the word is called in a first step Searched for the negative list, which contains words that are very common in web documents come, but under no circumstances for the automatic hyperlink generation in question come. In the German language, for example, there are many articles and pronouns and other non-keyword function words. A negative list from example up to a thousand words can be the number of running word forms of a text reduce about half. It becomes storage space and above all processing time saved, because the list can be kept in memory, to the Powers of ten faster than current external storage can be accessed.

The main method of database query in this implementation is a very quick ver drive, in which the search term is converted into a number using a suitable algorithm is calculated, which then serves to determine the index of the search term in the database. you calls this process "hashing". Especially the calculation algorithms used there are countless approaches to hashing. In the simplest In this case, the standardized search word is simply a number based on 256 (if used the ASCII character encoding) or to base 64 (when using the above described own character set) and used as an index for the database. In the In this case, the search term itself would not appear in the database because of the index is identical to the search term. The disadvantage of this simple procedure is that required large number of data records, the majority of which are not would be used. The advantage is the speed of the search, the better would be described as a calculation process.

A more practical approach, which also applies to the invention described here can find, is to limit the calculated indices to an arbitrarily determined  Size, which is an arbitrary order of magnitude the number of in the Database entries to be managed exceeds. The problem arises that differs search terms generate the same indexes. The search terms must therefore be in the Database.

If a calculated index falls on an unused rate of the Database, this index is used, otherwise the next one is not yet ver turned index. The search for a database entry then again consists of two Steps. First the index is calculated and then from this point in the database searched for the search term.

For example, if the size of the database is the number of database entries exceeds the factor two, when entering the terms is on average every second Free space. The result is that the term is very close to the calculated neten Index can be entered, which in turn very ver the search from this index shortens.

Since the number of database entries is known before the database is created, the The database management module described below is always an appropriate size according to the number of terms to be entered.

Hashing methods are state of the art. Further explanations are in the Computer science literature widely available. The procedure is based on the to be achieved The aim of processing parallel to the transfer and the resulting claim the speed best suited. However, other implementations are possible can also be expected in the future using faster hardware.

The database consists, for example, of the hash index, which contains the terms as well as references to a file, more precisely to an offset in a file where the Information associated with terms. This allows the index to be sufficient available memory can be kept in this what the processing speed increased. The file with the associated information is only accessed in the event of a "hit", therefore access to it is not the same Dimensions are time-critical.  

The assigned information is stored in the following fields:
"Actual word group": true or false if "Actual word group" is true, "Word group": as a string (without first word)
"Assignment": possible context assignments as a list of 3-digit byte values, sorted by frequency in common usage
"IstDirektlink": true or false if "IstDirektlink" is true, "DirektlinkURL": URL of the direct link as a string

Accordingly, the database module gives the query in the event of a positive result in addition to the answer "true" return a data record that contains the fields "actual word group", Contains "phrase", "assignment", "actual direct link" and "direct link URL". These fields are used by the analysis module according to their content to generate the anchor tags or other hyperlinks.

The database administration creates the database, manages updates, own extensions and blacklists.

To adapt the program system to the needs of the user as much as possible to enable this is preferably not included in the invention described here a static database. There should be the possibility of the scope as well as to control the content of the keyword list, if necessary your own Add words and phrases, and keep the keyword list up to date hold. Reducing the number may also be desirable, what is achieved by a blacklist, which the no longer include in the database contains the terms.

This is achieved through a management module belonging to the program system, wel ches during installation and each time changes are made from one or more source files Assignment file and the keyword list according to the hashing procedure described above generated. These source files can come from any source and in any formats are available as long as the administration module imports these formats supports.  

Possible sources for the implementation of the invention described here are the download the program system from the web and subsequent installation, or installation of a disk. For example, updates are available as downloads. For example, users can create their own favorite collection from their web browser integrate the desired keywords into the list or your own source file create. These are only possible sources, in principle, depending on the embodiment Source freely definable.

The final behavior of the program process is from the user, from web authors and / or providers of a corresponding service using the invention largely controllable, especially regarding the content and presentation. A tax moor For example, dul enables the user to customize the method according to the invention duel by changing the elements, the category structure and / or the elements adjust assigned resource information.

According to the invention, the control module is used by the user in particular to

• - to start the adaptation of the database or to define the adaptation rules for the database:
  The terms contained in the database and, in particular, any direct links assigned to them can be updated if the user explicitly requests this, or after a period of time to be determined by the user since the last update, or if the provider of the program system sends them a corresponding message about the expiry of the validity of the information.
• - to provide additional information for the automatic creation of hyperlinks if required:
  In order to enable the provider of an information service based on the invention to select the best possible results, the automatically generated hyperlinks can also be used to transmit additional information about the user at the express request of the user, for example about the local context or personal interests concerning.
• - to adapt the display of the automatically generated hyperlinks to his needs:
  In the embodiment described here, the user should be able to choose between different levels of attention generated by the automatically generated hyperlinks. For example, any visible highlighting could be dispensed with, in order not to influence the visual appearance and printout of documents in particular, without having to do without the automatically generated hyperlinks. A highlighting analogous to the representation of conventional hyperlinks generated by the web author could also be selected, or one that was only minimally different (e.g. a slight color difference). If the automatically generated hyperlinks are to attract more attention, a special display can be selected (e.g. colored background and / or special fonts).
• - to temporarily switch off the program system without permanently uninstalling it:
  This could be desired, for example, if a web browser is used alternately by several users who differ in their wishes with regard to automatically generated hyperlinks, or for other personal reasons of the user. In any case, it appears in the user's interest to allow the temporary deactivation.
• - To edit locally saved and / or not in HTML format present documents. The user can determine whether changed documents can be overwritten or saved as a copy.

The method according to the invention can be carried out on a single data processing device location, as well as on several interconnectable data processing systems It is conceivable that the method according to the invention is based on data processing system without any connection to a computer network. Likewise but it is also conceivable that the data, the elements of which are to be determined, from a Data processing system in a network is requested and the invention  Method steps then on one, possibly one from the computer network separate data processing system can be carried out again. Is further conceivable that the method steps according to the invention on different data processing systems on a computer network and the outcome of these steps another data processing system displayed or saved in the computer network is saved. The examples shown here are for illustrative purposes only but do not limit the possible variants. The term should also Data processing system should not be limited to computers, but all system and Include devices that can be used to process data, in particular the The term also encompasses systems and devices that connect to data processing work systems are suitable and have a graphical user interface.

According to the embodiment of the invention described here, the mapping and Linking the resource information with the at least one determined element already before the data is completely loaded into the memory of the at least one data processor processing system. This is particularly advantageous if, as with the WWW is the case, requested data can be divided into data packets and these Data packets reach the recipient in chronological order. If according to the invention already before the complete receipt of a requested file and thus before the full started loading the requested data into a data processing system the user will get results faster than if the full "Download which "a file should be waited for.

Inserting the resource specification in data in the form of a hyperlink has the advantage that the resource information stored in a hyperlink when the hyper is activated can be activated on the left by a suitable means and after activation a connection to the resource defined by the resource specification can be produced. This enables fast and flexible navigation and, especially in computer networks Do research. But it is also conceivable that the link between elements and Resource is specified, for example, in the form of a separate list that can be displayed and in which the resource can be activated by a suitable means and after activation  a connection to the resource defined by the resource specification is posed.

A particular advantage of the present invention arises when, as in the above case, a connection to a resource is established and then to the resource again the method according to the invention is used. So it becomes possible, for example from a file element contained in a file via a linked res source to go to another file and from there to a third u. s. w. Just here it becomes clear what advantage the method according to the invention has over Today's known and available options for navigation and research in size database is possible.

Another significant advantage of the present invention compared to the prior art Technology, which can be dispensed with either on a case-by-case basis or entirely can, is that the context reference for elements in new data as the basis for determining and assigning the resource information to the in elements determined based on the new data is used.

This embodiment is based on the idea that from one user to one Data processing system data is often related to each other content. Furthermore, z. B. Long, related text is often divided into different files. Requests For example, users enter a certain text from a computer network, so then, for example, only a first part of the text is transmitted in the form of a file. The user also wants the other parts of the text from the computer network received, he must request the files in which the remaining text is stored. Becomes now the context reference already determined for the first data for further data as the basis for the Determination and assignment of the resource information to that determined in the further file Elements, this is used - especially for the first elements of the others File - more likely to assign resources more "appropriately" c information lead than this without the use of already determined context assignments it is possible.  

The method according to the invention is of course not only more precise here described application limited in the area of the WWW. It can easily be on any files are applied, provided the files are in a format that enables the linking of file elements with resource information.

It is also conceivable that a file can be saved regardless of the original file format the inventive method is converted into a file format that the link enables file elements with resource information.

Finally, the method according to the invention can advantageously be used for who to select a selection from data, the items available in the selection determine to assign a resource specification to at least one of the determined elements and verifying the resource information with the at least one of the determined elements socialize.

The elements and links determined in this way can, for example, be separated from the Playback of the data are displayed optically and there is still the possibility that the resource information reproduced in this way can be activated by a suitable means and after activation a connection to the resource is established. It's one of those Established connection to a resource, in turn, can invent the resource procedures are applied. In this embodiment, the format plays in that the original data is available, does not matter.

The selection from the data and the activation of the resources can, for example by the known marking or clicking on a screen with a pointing device respectively. It is also conceivable that the selection by pressing certain buttons or key combinations on an input device. It is also possible for Selection of a touch-sensitive playback medium, such as a touch use sensitive screen. After all, it is conceivable that the end choose timed, that for example a selection is made when the Cursor (the sight mark) stays near data for a predeterminable time.  

The computer program product according to the invention and / or the data carrier on which the computer program product according to the invention is stored, is used for implementation of the method according to the invention.

Because of the description of the method according to the present invention, it is that One skilled in the art can readily produce the device according to the invention.
