Abstract

The invention relates to a data processing system and a method for displaying information on a graphic user interface of a mobile terminal, wherein both reference to information of a first type (NTK) are displayed to the user, which information is to be displayed in any event on calling up an application, and references to information of a second type are displayed to the user, the display of which depends on an interest of a user, without the user explicitly and specifically needing to request the second information.

Description

Data processing system

The invention relates to a data processing system for the dynamic processing of data representing data sets in at least one database. The data processing system comprises at least one mobile terminal as a front-end with a graphical user interface for retrieving and presenting information. In addition, the data processing system comprises at least one server as a back-end with a data communication interface for data communication with the mobile terminal.

Data processing systems for processing information representing information are known in the art in various forms. EP 1 685 505 B1 shows a data processing system for the dynamic detection of weighted relationships between data representing information in at least one dataset. The data processing system has means to also detect a relationship as a link between an information-representing date of a data stock and another data-representing date of a data stock as a date representing an information. The data processing system independently determines and keeps the connections up-to-date. The relationships are dynamically detected as gain-weakenable modifiable n-to-n links (n is a natural number). The link is generated by a semantic comparison of the information representing data of a connection request and the information representing data of the database. In the context of the semantic comparison, a semantic network is generated from which correlations can be detected. Dynamic relationships are detected by semantic comparisons on the basis of or by means of the sequence of information representing data of databases and uses of information representing data of databases. The correlation is weighted. The relationship weighting of at least one relationship that has already been recorded in a dataset as an information-representing datum is changed by increasing or decreasing as a function of the context weighting of a subsequently recorded relationship. The data processing system logs the sequence of all data of a data that has been retrieved or used. If this sequence occurs several times and if two data representing a data stock follow one another and the link is strengthened, a latent link is created.

In a data processing system of the type mentioned above, there are some challenges and problems that need to be solved:

Mobile devices have limited data communication bandwidth and limited computing and storage capacity.

The limited size of the graphical display, as well as the requirement for finger operation, allows only a limited user interface for applications and limits the amount of information to be displayed, so that not all information basically available to a user can be offered to the user for selection.

Known approaches for machine-aided finding of relevant information, eg collaborative filtering, require a priori information in order to function, ie missing information in the initial use can impair such systems (cold start problem). Another problem is that the user does not know which of the information that may interest him exists. Therefore, no explicit query of this information is possible. The object is to provide a data processing system that makes it possible for a user to display relevant information on a mobile terminal.

For this purpose, a data processing system with at least one server and at least one mobile terminal with a graphic display is proposed. The server is designed to access information-representing data records and to provide the data records each with a data record identifier, as well as to allocate the respective data record identifier to one or more different indices on the basis of information contained in the data records.

Furthermore, the server is configured to form an inverted index data structure in which one or more record identifiers are respectively assigned to one or more indices if a respective record identified by the corresponding record identifier contains an information represented by a respective index.

Furthermore, the server is configured to manage a sequence of filters defined by one or more of the indices and configured to determine a selection of a respective data set in consideration of the information represented thereby. That The configuration of the respective filter determines which data record the server selects when the respective filter is called.

The server is further adapted to transmit, in response to a request message from a terminal, data indicative of information contained in a respective record determined by a respective one of the filters from the sequence of filters.

The mobile terminal is designed to establish a data communication connection to the server after calling a corresponding application, preferably installed on the mobile terminal, and to transmit to the server a request message, which preferably contains a user identifier.

Furthermore, the mobile terminal is configured to receive from the server data representing indications of information contained in a respective data record determined by means of a respective one of the filters from the sequence of the filters. Furthermore, the mobile terminal is designed to display information represented by the received data on the graphic display and to a corresponding input To call a user associated with a respective note information and bring to display, as well as to send a message indicating a respective call to the server.

Data representing indications of information should be understood here to mean that the data contains an indication of information represented by the respective selected data record.

Preferably, the sequence of filters comprises at least one dynamic filter configured by having associated with it both a user identifier and a plurality of record identifiers. The server is adapted to apply the dynamic filter such that it selects a data set upon receipt of a request message containing a user identifier from the terminal based on the indices associated with the records identified by their respective record identifier and data indicative of present information represented by a respective record selected in this way, to which the mobile terminal transmits, so that the indication can be displayed on the graphical display of the terminal.

Furthermore, it is advantageous, if the server is designed, after receiving a respective message indicating a call, a data record identifier which identifies the data record representing the called information, to be associated with the corresponding dynamic filter.

Advantageously, the server may be configured to determine further data records to which the corresponding indices are assigned on the basis of the indices to which the data record identified by the stored record identifier assigned to the dynamic filter is assigned, and the dynamic filter by means of the record identifications of these data records to configure. The configuration of the dynamic filter can thus follow the interests of a user without the need for a conventional user profile. Although the configuration of the dynamic filter is for example keyword-based, it is nevertheless purely speech-diagnostic, ie the system does not need any information about the meaning of the information represented by the data records, eg the words contained in the data records. This allows a simple technical realization for all conceivable languages. The latter may be assisted by the server in being adapted to receive, upon receipt of a further request message containing a user identifier, based on the configured dynamic filter - via the indices associated with the records identified by the record identifiers by which the dynamic filter is configured in each case - to determine and select a record and to transmit an indication of information contained in this record data representing the mobile terminal.

The dynamic filter may be configured by multiple sets of record identifiers, and the server may be configured to apply to such call of the dynamic filter those indexes for selecting a record associated with those records whose record identifiers each form a group. In this way, a user can be made aware of different information over time by means of a filter.

A dynamic filter implementing the aforementioned features, based on the record identifier in the inverted index data structure, retrieves the index or indexes to which the corresponding record is associated and identifies further records, the corresponding one, by means of the index or indices Indices are assigned. The server is configured to store the record identifications associated with the data records identified in this way and to select a record representing information when the user re-invokes the application on the basis of the indices to which the records identified by the stored record identifiers are assigned, and an indication of this selected information record presented on the mobile terminal to the latter to be transmitted, whereupon the corresponding reference to the information of the second type is displayed on the mobile terminal.

The data to be sent by the server to the mobile terminal, which represent an indication of information contained in a respective selected record, may advantageously contain, in addition to this indication, at least one URL that refers to the selected record, so that it may be requested by a user can be called. The record may be, for example, a web page.

The data representing data sets are preferably those containing at least one text information containing at least one word. The indications of data representing data records transferred from the server to the mobile terminal. gene, preferably contain at least one text information containing at least a summary of a record representing the respective information.

In a particularly preferred embodiment variant, the mobile terminal comprises an application backend, which is designed to effect on the touch-sensitive graphical display of the mobile terminal a reproduction of the information represented by the received data in the form of maps. Additionally, the application backend is configured to capture and process events that represent a swipe gesture and, upon detecting a swipe gesture, provide a next indication of a sequence of indications for display on the touch-sensitive graphical display. In this way, a sequence of hints can be brought to the attention of a user on a small-area graphic display, without the need for buttons or the like, so that the limited area of the graphic display can be completely available for displaying the clues. Status displays or the like of the mobile terminal remain unaffected.

In addition, the application backend is preferably configured to cause references to records and the information represented thereby to be sequentially displayed in two different ways, depending on what kind of records are or the information represented by them, or from which data source the data records or the information represented by them originate.

The two last-mentioned aspects, which are realized by the application backend, can also be implemented independently of the selection of the respective data records and represent in this sense an independent idea of the invention.

In this sense, a mobile terminal is also proposed, which is designed to cause references to data records and the information represented by them either as a stack of cards or as a sequence or sequence or band from edge to edge of successive cards on a graphic display of the mobile terminal, depending on the type of data records or the information represented by them, or on which data source the data records or the information represented by them originate. The application backend can furthermore be configured such that information of a second type to be displayed by means of a card stack can be called up at any time when viewing the cards in the form of a continuous band with information of a first type. The deck of cards can then appear above the ribbon of cards. For example, information such as mobile boarding passes, travel plans, or basic system information may be retrieved as second-order information at any point in time as a deck of cards, while other information, messages, or weather or system background information (workload, etc.) may be presented side by side as side-by-side maps become. In order to achieve the above object, a method for displaying information on a graphic user interface of a mobile terminal is also proposed, wherein the user firstly receives information on a first type of information (WTK) to be displayed when invoking an application in each case and secondly, references to information of a second type (NTK), the display of which depends on a user's interest, without the user having to explicitly and specifically request the second information.

It provides one or more servers and one or more mobile devices that can communicate with the server.

The server is connected to databases containing records representing the information. The datasets can be stored on the same server or the server can be connected to another server where the datasets are stored. The server allocates available information representing records to various indexes in an inverted index data structure. It is advantageous if the server first converts the data records representing the information into a sequential data structure in which information contained in a data record representing each information is assigned as values (values) to different keys (keys).

The inverted index data structure preferably includes indexes representing key information and associated therewith record identifiers of those (information representing) records containing respective key information. The mobile terminal establishes - after a user has invoked a corresponding application - a data communication connection to a server and transmits the server a user identifier.

Thereafter, the server transmits to the mobile terminal first data containing clues to the information of the first kind and second data containing clues to information of the second kind.

The references to the information of the first type and the references to the information of the second type are provided on the mobile terminal such that a user provides the references to the information of the first type and the references to the information of the second type successively on the graphical user interface can retrieve information associated with a particular note as needed.

The mobile terminal transmits a message indicating a respective call to the server in the event of a call of information. Thereafter, the server stores a data set identifier identifying the retrieved information and assigns it to a dynamic filter specific to a respective user identifier,

The dynamic filter, based on the record identifier in the inverted index data structure, retrieves the index or indexes to which the corresponding record is associated and identifies further records associated with corresponding indexes using the index or indices. The record identifiers associated with the records thus identified are stored and form a set of record identifiers associated with different indexes in the inverted index data structure. The dynamic filter is thus indirectly configured by several indices. The filter selects an information representative record when the user re-invokes the application based on the indices associated with the records identified by the stored record identifiers.

To the selected record, the server transmits to the mobile terminal an indication of the information represented by the selected record. This notification causes the mobile terminal to display a corresponding reference to the information of the second type on the mobile terminal. Through a sequence of filters, the server can thus determine a sequence of records and generate a sequence of indications of information contained in the records representing data and transmit it to the mobile terminal, where a user can retrieve the hints one after the other. The sequence of filters may include one or more dynamic filters (as described earlier) and static filters that are hard-coded.

An advantage of this method is that it can be dispensed with a semantic comparison.

The data representing data sets may be, for example, files that represent words containing words. An advantage of the method is that it is independent of the language of the text used.

The invention will now be explained in more detail by means of embodiments with reference to the figures. From the figures is

Figure 7: an illustration of the operation of the application front end in the

Display hints to a second type of information. A data processing system according to the invention comprises at least two components, namely a backend server 10 and a mobile terminal 12. In fact, however, the data processing system is designed to have a plurality of mobile terminals 12 associated with different users. Likewise, a plurality of servers 10 may be provided.

The backend server 10 itself provides additional resources of the data processing system and is also connected to other resources. The same applies to these mobile terminals 12.

In particular, the backend server 10 has the following features: It is connected to a mobile radio network for bi-directional transmission from and to the mobile terminals.

He has access to information representing records.

It manages an inverted index data structure based on indices and associated record identifiers that uniquely identify a record representing each information.

It manages and processes a sequence of filters, each filter being the basis for selecting a record by the server.

It transmits a sequence of indications of data representing the content of the selected data records to a respective mobile terminal 12. Some of the further resources of the data processing system are shown schematically in FIG. As can be seen from FIG. 2, the back-end server 10 comprises a content management system 14, which serves for the administration of data records and the information represented by the data records. In addition, the back-end server 10 includes an application backend 16, which has the function to select from the plurality of provided by the content management system 14 records some records and to generate clues to these records, which - represented by appropriate data - to be transmitted to the respective mobile terminal 12. For this purpose, the mobile terminal 12 has a corresponding application front-end 18 which processes received data with instructions and also the information contents of the selected data records in such a way that the instructions can be displayed successively on a graphic display 20 of the mobile terminal 12. A user may click on a respective displayed indication on the touch-sensitive graphical display 20 and thus call up the record associated with the reference. The call of the respective data record can, for example, be made using a URL which refers to the respective data record.

The application front end 18 may be installed as an application on the mobile terminal 12 so that it can be executed by the mobile terminal 12. As FIG. 3 shows, the mobile terminal 12 has, in addition to the touch-sensitive graphic display 20 with an associated driver and read-out unit 22, a processor 24 which is connected to the touch-sensitive graphic display 20 via the driver and readout unit 22. In addition, the processor 24 is connected to a memory 26 and a data modem 28. The data modem 28 serves for bidirectional data exchange via a mobile radio network and thus permits data exchange with the server 10.

The server 10 is also at least indirectly connected to a mobile network. In addition, the backend server 10 is connected to a data rendering system 30 (see FIG. 2), which in turn is connected to a plurality of data sources 32 typically over the Internet. The data processing system 30 is configured to query the various data sources 32 via a crawler 34 and to collect information obtained from the data sources 32. The information obtained from the data sources 32 is processed by the data processing system 30 and condensed into data records that can be supplied to the content management system 14.

From the data obtained from the data sources 32, the data preparation system 30 generates a sequential data structure in the JSON format, in which the information contained in the respective data record is assigned as values (values) to different keys (keys). In addition, the records are assigned individual record identifiers. Record identifier key: value

122 word: football, elections, stock market

1346 Word: stock market, elections fair

1600 Word: Fair, Stock Exchange

Word: population growth,

161 1

Hungry, stock market

By means of the sequential data structure and the data record identifications, the data processing system 30 generates an inverted index data structure in which the individual data record identifiers are respectively assigned to one or more indices. A respective index represents a key information.

A respective data record identifier is always assigned to a respective index if the associated data record contains the key information for which the respective index is located. This in turn results from the previously formed sequential data structure by the various indices (eg: population growth, hunger) are formed from a respective key (for example: word) associated values (eg: football, elections, stock market, fair, population growth, hunger) and a data record identifier is always assigned to these indices if the associated data record for the respective key (eg topic) contains a corresponding value (eg world population and / or hunger).

By means of the inverted index data structure and a list of filters, the application back end 16 selects one data set per filter in each case, and then selects the respective one Content representative note that can be processed by the application front-end 18 on the mobile device 12 and displayed on the graphic display 20.

A respective filter thus determines which data record the application back end 16 selects in each case. This selection is done using indexes that configure the filter. Such a configuration of a filter can be done directly by the indices directly defining the filter. However, a filter can also be indirectly configured by means of indices by assigning record identifiers to the filter, which in turn are assigned to different indices via the inverted index data structure. These indices, which are assigned the record identifiers assigned to the respective filter, configure the corresponding filter indirectly. A selection of a respective data record is carried out by filtering the available data records on the basis of the indices defining the filter. Another selection criterion may be, for example, the age of a data record. The filters form a sequence of filters which also determines the order in which the indications are displayed on the mobile terminal 12, which refer to the records selected by the respective filters.

Some of the filters can be dynamic filters. A dynamic filter is not configured by a single group of indexes or record identifiers, but by multiple groups of indexes or record identifiers. This allows the indices or record identifiers used in this call to be replaced by other indexes or record identifiers of a second group the next time the same filter is called after a single call to the filter. In this way, in spite of a predetermined sequence of filters, it can be effected that a user does not always receive more or less identical data records or references to data records, but rather has the opportunity to perceive further information from the multiplicity of information.

In addition, a dynamic filter can also replace a group's indexes or record IDs with other indexes or record IDs, creating a different, new set of indexes or record IDs. In particular, the filter may be designed such that indices or record identifiers of a group are then replaced by other indices or record identifiers, if the data record, by means of the respective filter and the corresponding group has been selected by indices or record identifiers, has actually been called by the user by the user having clicked on the corresponding note on the touch-sensitive graphical display 20 of the mobile terminal 12. A replacement of the indices or data record identifications of a group of indices or data record identifications of the corresponding filter can be carried out in such a way that a plurality of further data records which are assigned to the same or similar indexes as the called data record are determined on the basis of the record identifier of the called data record. The record identifiers associated with the records thus found replace the previous record record identifiers in the last accessed group of record identifiers to be modified and thus reconfigure the corresponding filter. Alternatively, the record identifiers as described may also be added to the filter as a new set of record identifiers. The most recently accessed group of record identifiers can then be kept latent, for example, and later reactivated or completely removed from the filter. Groups of record identifiers or indices may also be removed by a dynamic filter if the indication of the record selected by the respective group of indices or record identifiers has been displayed once or more to a user without the user having invoked the corresponding record. In this way, dynamic filters can be adapted to the needs of a user without having to create complex user profiles. In addition, since the filters are configured solely on the basis of indices that can represent, for example, natural-language words in data records, the filters can also operate entirely in terms of speech diagnostics and without consideration of semantic contexts. Therefore, the application back end 16 can be implemented comparatively easily and sparingly.

Figure 4 is a graphic illustration of the operation of a dynamic filter. For example, in the illustrated sequence 50, which in the illustrated example is formed by sixteen filters 52, the fourth filter and the twelfth filter are dynamic filters 54, which are illustrated in FIG. 4 in the manner of a wheel with spokes. The points at the ends of the spokes of the wheel represent groups 56 of indices or record identifiers. In the concrete exemplary embodiment, these groups are respectively groups of data set identifiers, so that the indices used to select a data set when the respective group is called are the indices to which the data set identifiers associated with the group belong inverted index data structure are assigned. With each call to the dynamic filter 54, the filter "rotates" one position further, so that when the filter 54 is recalled, the next group 56 of indexes or record identifiers is used to select a record. For example, additional sets of record identifiers may be added to the filter 54 or groups of record identifiers may be removed if, for example, a record selected by a respective set of record identifiers is not retrieved Record identifiers are replaced.

The described sequence of filters with the dynamic filters described may include, in addition to the dynamic filters 54, also static filters defined by a fixed group of indices or record identifiers, or directly configured by means of a record identifier, such that upon invocation of a corresponding static filter the record is generated to which the corresponding record identifier is assigned.

The sequence 50 of filters with the described static and dynamic filters is part of the application backend 16 in the backend server 10.

Calling and controlling the application backend 16 takes place in data exchange with a respective mobile terminal 12. Typically, the application backend 16 holds a separate sequence 50 of filters for each user of the data processing system, as a result of which user-dependent reconfiguration of the dynamic filters is user-specific is.

FIG. 5 illustrates the flow of data communication between mobile terminal 12 and back-end server 10 and an arbitrary content server 32. FIG. 5 also illustrates the response of back-end server 10 to messages from mobile terminal 12.

As previously mentioned and indicated graphically in FIG. 2, an application that provides an application front end 18 is installed on the mobile terminal 12. The application front-end is configured to generate data which, on the touch-sensitive graphical display 20 of the mobile terminal 12, causes the display of indications of information contained in data records and the display of buttons. The application front end 18 is also designed to handle events such as For example, detecting and processing the touch of the touch-sensitive graphic display 20 at specific locations.

It should be appreciated that an application forming the application front end 18 may be installed on the mobile terminal 12, but alternatively on another device, so that a web application may be invoked on the mobile terminal instead of a locally installed application.

Use of the data processing system according to the invention begins with a user calling the corresponding application on the mobile terminal 12 and thus starting the application front-end 18. This then causes the mobile terminal 12 to first direct a request message to the backend server 10. The request message in the preferred embodiment includes a user identifier and thus allows the application backend to invoke a sequence of filters that may be specific to the particular user.

On the basis of the called sequence 50 of filters, the application back end 16 then determines a sequence of data records by selecting a data set in the manner described above by means of a respective filter. To the sequence of records, the application back end 16 generates a sequence of hints and transmits the data representing the clues to the application front end 18. The clues representing clues include both clues to information represented by a respective record and a reference, such as a URL that leads to the respective record.

The application front-end 18 processes the data received from the application back-end 16 and generates signals that cause the indications on the touch-sensitive graphical display 20 of the mobile terminal 12 to be displayed. In this case, the references to the data sets determined by means of the sequence 50 of filters are displayed in the order in which they are predetermined by the sequence 50 of the filters. Specifically, the application front end 18 is configured to always display exactly one indication on the touch-sensitive graphical display 20 of the mobile terminal 12. A corresponding gesture can cause a user to hide a hint and display the next hint. The application frontend 18 is configured to process events triggered by corresponding gestures. As soon as a respective indication is displayed on the touch-sensitive graphical display 20 of the mobile terminal 12, the application front-end 18 generates a message indicating the display of the message and transmits it to the application back-end 16. As already mentioned, a user can make a corresponding gesture that a respective hint is hidden and replaced by a subsequent reference. Alternatively, however, the user can also call up the record associated with a respective reference, for example by a different gesture. A gesture for hiding a hint and calling a next hint may be, for example, a swipe gesture. A gesture to invoke the record associated with a note may be a click. Accordingly, the application front-end 18 is designed to process different events triggered by such gestures in a differentiated manner.

If a user invokes the associated dataset by clicking on the hint - more precisely: calls the information represented by the associated dataset - the application front-end 18 generates a message indicating a corresponding call and transmits it to the application back-end 16. As described above, causes the receipt of a message indicating a call to cause the application back end 16 to reconfigure a filter 52 of the sequence 50 of filters belonging to a respective hint, if this filter 52 is a dynamic filter that can be configured. Reconfiguring the corresponding dynamic filter means that the next time this filter is called, another group or a modified group of indices or data record identifiers is used to select a particular data record. Clicking on a hint by a user also causes the application front end 18 to follow a link associated with the particular hint and invoke a corresponding link or URL to retrieve the record associated therewith. Typically, the reference to a record refers to a content server, i. the link or URL leads to the content server that holds the corresponding record.

The data sent from the backend server to the mobile terminal upon receipt of a request message may represent a respective record in various ways. In one embodiment, a respective one contains, on the information to be displayed on the mobile terminal 12 in addition to text, for example an image. In this case, the data representative of the hints sent from the backend server to the mobile terminal need not include the image itself. Rather, the data representing hints may include a reference, such as a URL, that leads to the corresponding image. The application front end 18 may then download the corresponding map, preferably in a preconfigured form, from a corresponding mapping server 36; see FIG. 2.

In the following, some of the resources or messages of the data processing system are presented once more:

The backend server 10 has access to records representing information, e.g. Texts, news websites etc.

The backend server 10 uses record identifiers, each of which is an individual, unique identifier of a record representing information. The backend server 10 creates and maintains an inverted index data structure. This contains indices, each of which has one or more record identifiers associated with it, depending on whether a respective record (represented by its record identifier) contains information for which a respective index stands.

The backend server 10 includes an application back end 16 which uses filters to select information to be displayed. A respective filter is configured directly or indirectly by one or more indices and causes the backend server 10, based on the indices that configure the respective filter, to select a data record to which the server transmits information representing data to the mobile terminal 12. A respective filter may be configured by means of record identifiers, with the indices configuring the filter then being the indices to which the data records identified by the record identifiers are assigned.

Filters can be dynamic filters. A dynamic filter is reconfigured upon receipt of a call-indicating message by the server, by further identifying records based on the indexes associated with a called record whose record identifiers are then stored to (re-) configure the filter associated with it. A dynamic filter can be defined by several groups of record identifiers, with each (re-) calling of the respective filter serving another set of groups of record identifiers as the basis for the selection of a record by the server. In the case of a dynamic filter configured by more than one set of record identifiers, a respective set of record identifiers that resulted in the selection of a retrieved record is reconfigured in the manner described.

This allows a dynamic adaptation of the data processing system for displaying user-relevant data records completely speech -agnostic and with purely technical means. An explicit specification of user preferences or use of user profiles 40 of a conventional type can additionally be provided.

The filters form a sequence 50 of filters which are called in turn by the server so as to determine a series of records to which the server then transmits clues representative data to the mobile terminal where the indications represented by the data are Contents of the records are displayed in the appropriate order.

Data and messages exchanged between backend server 10 and mobile terminal 12 include: a user identifier that is a user's unique identifier and is dedicated to a user. A user can identify themselves by calling username and password when calling an application. a request message, which is a message from the mobile terminal 12 to the backend server 10 and which contains a user identifier and causes the server to transmit (indicia representative) data to the mobile terminal, each representing references to information in a sequence of Da - The rates are included, the server for a user based on a

Sequence of filters.

Hints representing data, each associated with a selected by the server record and transmitted from the server to the mobile terminal and containing the display on the graphical display of the mobile device information contained in the respective selected record information and a URL containing a call of the respective data record. a call-indicating message, which is a message transmitted from the mobile terminal to the server, when a user calls up a record represented by an indication by, for example, clicking on the indication on the touch-sensitive graphical display of the mobile terminal. Figures 6 and 7 illustrate the operation of the application frontend 18 in displaying indicia of a first or second type of information. The application front-end 18 is designed such that references to data records and the information represented by them are displayed sequentially in two different ways, depending on which type the data records or the information represented by them or of, are which data source the data sets or the information represented by them come from.

Such a different but nevertheless sequential presentation of references to data sets of different types allows an implicit differentiation of the data records that is implicit and easily recognizable by the user without any further additional information. This facilitates the information perception by the respective user.

The various representations of the clues depending on the nature or origin of the records to which the clues refer represent an aspect of the invention which is independent of the other aspects of the invention, in particular independent of the selection of the records by the application backend 16 by means of the filters 52 and 54, respectively.

The application front-end 18 is designed to display the notes as cards that can be called successively by swiping gestures.

In this case, references to records of the first type are displayed as a band from edge to edge successive cards. A swipe gesture corresponding to a shift-up of the map 60a indicative of the effect causes the band to advance one card at a time, one after the other, thereby indicating the next card 60b. The band of cards thus represents a sequence or sequence of clues that are displayed side by side.

Actuation of the button 62 - ie, touching the touch-sensitive graphic display within a designated area - causes a display of a stack of stacked cards 64, indicative of records represent the second kind. A swipe gesture corresponding to a removal of the topmost card is provided to display the underlying card. When the bottom-most card 64 of the stack is pushed away, the tape of the first-type records 60 again appears, with a respective card 60 being displayed as the record-hinting button 62 of the second Type was pressed.

In the exemplary embodiment, references to records derived from the data sources 32 are displayed as a band of cards 60, while references to records derived from another data source 38 (see FIG. 2) are represented as a stack of cards 64.

The call of references to the second type of data records is carried out in the exemplary embodiment by means of the button 62. However, such a call can also be implemented differently, e.g. by swiping gesture. The application front end 18 is configured to detect and process events representing corresponding inputs.

Also, a change between cards of the tape or the stack can be implemented differently than by swipe gestures, eg by means of corresponding buttons. Swipe gestures, however, are preferred because no display surface is lost for otherwise provided buttons.

Claims:

1. A data processing system comprising at least one server, at least one mobile terminal with a graphical display and wherein the server is adapted to access information representing data records to provide the records each with a record identifier and on the basis of information contained in the records the respective record identifier one or a plurality of indices to form an inverted index data structure in which one or more record identifiers are assigned to one or more indices, respectively, when a respective record identified by the corresponding record identifier contains an information represented by a respective index, a To manage a sequence of filters defined by one or more indices and configured to determine a selection of a respective data set for information represented thereby. in response to a request message from a terminal, transmitting data representing indications of information contained in a respective record determined by a respective one of the filters from the sequence of filters, and wherein the mobile terminal is adapted to upon invoking a corresponding application, establish a data communication link to the server and transmit to the server a request message from the server for receiving data indicative of information contained in a respective record determined by a respective one of the filters from the sequence of filters to display indications represented by the received data on the graphic display, and to call and display information linked to a corresponding input of a user with a respective notice and to transmit a message indicating a respective call to the server.

Data processing system according to claim 1, characterized in that the sequence of filters comprises at least one dynamic filter configured by having associated therewith both a user identifier and a plurality of record identifiers, the server being adapted to apply the dynamic filter such that upon receipt of a request message from the terminal containing a user identifier, it selects a record based on the indices associated with the records identified by their respective record record identifier, and assigns data indicative of information represented by a respective selected record the mobile terminal transmits, so that the reference to the graphical display of the terminal can be displayed.

A data processing system according to claim 2, characterized in that the server is adapted, upon receipt of a respective message indicating a call, a record identifier (Doc-ID) identifying the record containing the called information represents associated with the corresponding dynamic filter store.

Data processing system according to claim 3, characterized in that the server is adapted to determine on the basis of the indices to which the data set identified by the dynamic filter associated record set record, to determine further data sets, which are associated with the corresponding indices, and the dynamic filter using the record IDs of these records to configure.

Data processing system according to claim 4, characterized in that the server is adapted, after receiving another request message containing a user identifier based on the configured dynamic filter on the indices associated with the records identified by the record identifiers by which Each of the dynamic filters is configured to determine and select a record and to communicate data indicative of information contained in that record to the mobile terminal.

Data processing system according to at least one of claims 2 to 5, characterized in that the dynamic filter is configured by a plurality of sets of record identifiers and the server is adapted to apply in such a call of the dynamic filter such indexes for selecting a record to which those records are assigned whose record identifiers each form a group.

Data processing system according to at least one of claims 1 to 6, characterized in that the data to be sent by the server to the mobile terminal, which represent an indication of information contained in a respective selected record, contain, in addition to the hint, at least one URL referenced to the selected record.

Data processing system according to at least one of claims 1 to 7, characterized in that the mobile terminal comprises an application backend, which is adapted to effect on the touch-sensitive graphical display of the mobile terminal, a reproduction of the information represented by the received data in the form of maps and to record events and to process, which represent a swipe gesture, and to bring about a next clues from a sequence of clues for display on the touch-sensitive graphical display upon detection of a swipe gesture.

Data processing system according to claim 8, characterized in that the application backend is adapted to cause references to data sets and the information represented by them to be displayed sequentially in two different ways, depending on which type of data sets or by these or from which data source the data sets or the information represented by them originate.

Method for displaying information on a graphic user interface of a mobile terminal, wherein the information to be displayed comprises references to information of a first type (NTK), which are to be displayed in each case when calling an application and, on the other hand, references to information of a second type (WTK), which depend on the interests of a user and which are provided without the user having to explicitly request references to specific information of the second, and wherein the server is connected to databases containing data representing information sets, and wherein the Assigning servers available, information representing data sets different indexes in an inverted index data structure, characterized in that the mobile terminal after calling the application establishes a data communication connection to a server and the server a user ID over center whereupon the server transmits to the mobile terminal first data containing indications of the first type of information (identifying / representing the first information) and second data representing information of the second type, the references to the information of the first type and the references to the information of the second type are provided on the mobile terminal in such a way that in that a user can retrieve the indications of the first type of information and the indications of the second type of information one after the other on the graphical user interface and invoke information associated with a respective indication as needed, wherein the mobile terminal in case of a call a Information transmitted to the server a message indicating a respective call, whereupon the server stores a record identifier identifying the accessed information record and assigns it to a filter that is specific to a respective user identifier, wherein the filter is formed based on the record identifier in the inverted Index data structure to call the index or indices to which the corresponding record is associated and to identify, by means of the index or indices, further records associated with corresponding indices, and the records thus identified and, upon re-invocation of the application by the user, select from the indices associated with the records identified by the stored record identifiers an information representative record and an indication of the information represented by the selected record to be displayed on the mobile To transmit terminal to this, whereupon the corresponding reference to the information of the second kind is displayed on the mobile terminal.
