Description

method to automatically compare and rate search profiles For example, in. Search engines used on the internet to the individual from the search engines examined possible results on their Relevance to the to evaluate entered search terms and, where relevant, as relevant Display result. If several results are determined, then these become sorted with decreasing relevance and the user in the corresponding Order shown.

From the DE 100 34 694 A1 For example, a method for automatically comparing and evaluating information is known, with which a rating is possible which is very similar to the evaluation by a human and is achieved with a low computational effort. The procedure compares structured profiles in individual data fields. In the method different comparison functions are used for the different types of data fields, with which preliminary comparison values are calculated. As a result, the contents of the individual data fields can be compared and evaluated on a type-specific basis. The provisional comparative values are then used to calculate a final comparative value.

The Method aims to compare profiles, e.g. on the Internet from where a rating over the degree of agreement the profile is in the foreground. To what extent and in what way a Contacting or exchanging data between the back Profiles are available, remains open.

Out US 2002/0034292 A1 is a method for matching a request with an offer based on a geographical location known. The synchronization is done on a server. Further the location of the participants must be determined.

It It is therefore an object of the present invention to specify a method which can easily exchange data between two Participants, each of which has a profile assigned, allows.

These Task is through a procedure as well as a computer program with Program code means and a computer program product for exchanging data with the features according to the respective independent Claim solved.

The Computer program with program code means is set up to all Steps according to the method of the invention to perform, if the program is running on a computer.

The Computer program product stored on a machine-readable medium Program code means is arranged to perform all steps according to the method of the invention perform, if the program is running on a computer.

The Device and the computer program with program code means, set up around all steps according to the inventive Perform proceedings, when the program is run on a computer, as well as the computer program product with program code means stored on a machine-readable carrier, arranged around all steps according to the inventive method perform, if the program is run on a computer, are particularly suitable to carry out the method according to the invention or one of its further developments explained below.

preferred Further developments of the invention will become apparent from the dependent claims.

The further developments described relate both to the procedure as well as on software-technical implementations.

The Invention and the further developments described can both in software as well as in hardware, for example using a special electrical circuit can be realized.

Further is an implementation of the invention or one described below Continuing education possible by a computer-readable storage medium on which the computer program is stored with program code means, which is the invention or continuing education.

Also can the invention or any further development described be realized by a computer program product, which is a Storage medium on which the computer program with program code means is stored, which performs the invention or training.

In a method for exchanging data between a first subscriber, to whom a first profile is assigned, and at least one second subscriber, to whom a second profile is assigned, the subscribers use a data menu The interface provides the ability to form an adhoc network. Furthermore, there is a direct communication between the first participant and the second participant. The data exchange takes place if, after a comparison of the first and the second profile, a match or similarity has been established and the first and the second subscriber are in a certain location area.

to Use of the procedure, it is necessary that the location information of each participant Ideally, continuously, but at least regularly within certain time window is known.

The Invention allows a mobile comparing a first profile, for example a search profile is, with at least a second profile, for example an offer profile is. It is in particular a personalized one Compare and rate offers and demands in the local Environment of mobile devices. This also implies the meaning of the term location area. It is the current geographic location of the or the participant at the given time to which a data exchange he follows.

at the method according to the invention is especially intended for mobile applications. More precisely means this is because the participants are preferably mobile. At the participants For example, it may be a mobile terminal, such as a mobile terminal. a mobile phone, an organizer (PDA), a transportable Computer or similar act, thus to terminals with the possibility for wireless data exchange. In the application of the procedure However, it is not mandatory that all participants are mobile terminals represent. It is also conceivable that the first participant mobile and thus exchanges its data wirelessly, while the second participant is wired. This will be better from the description below become apparent.

The Method for comparing the first and second profile and the Evaluation in terms of their similarity or match is also referred to as matchmaking.

The Procedure instructs the participants on interesting, specific to him tailored offers or demands in its immediate Environment, and allows Thus, the participants in the local environment to exchange data and directly contact the mediated subscriber.

The Participants represent the nodes of an ad hoc network. Communication thus runs "peer-to-peer". The data transfer interface Can be used as wireless LAN, Bluetooth or infrared interface be educated.

In In a first variant, the location area is defined by the transmission radii the data transmission interfaces established. In one embodiment, it is provided that the participants by means of a data transmission interface the ability to Formation of an ad hoc network and the location area by the transmission radius of a Exchange is determined, over which a communication between a first and a second participant takes place. The Switching center may, for example, a base station or a so-called "Access Point " Participants, in turn, represent nodes of the ad hoc network the communication still takes place "peer-to-peer", that makes it possible Provide the switch an increase in range and a increased Bandwidth. Characteristic of this variant is the fact that the Exchange the location area of the marketplace, in which a Data exchange possible is, determines.

The Peer-to-peer communication has the following characteristics: It is the waiver of a given infrastructure possible. The inventive method takes place only with the participants, respectively the terminals. It follows that each participant manage his profile and save in yourself. He also has the ability have to recognize another participant in the location area and communicate with it. Immediate consequence of it is that the comparison of the first and the second profile by the first and / or the second participant has to be done. With In other words, this means that the matchmaking takes place respectively each participant carried out himself must become. It is still necessary to take into account that a notification with successful similarity or match also possible must be, if the respective participant again the location area leaves.

In In another variant, the participants make nodes of a network where communication is via the infrastructure of this network takes place. In this variant does not find any direct communication between the participants as described above. The network can be considered a client-server network the infrastructure of transmitting and receiving stations and the corresponding central processing units. It can be concrete In such a network, the infrastructure of a GSM, Act GPRS or UMTS mobile network.

In this variant, the profiles of the subscribers can be stored centrally in the network the. It is advantageous if the comparison of the first and the second profile by a device, for example, the said central unit, the infrastructure of the network takes place. To carry out the method, it is then only necessary for the participants to inform the central unit of the network at regular intervals or continuously of their position.

The matchmaking, ie the comparison and the evaluation of the first and the second profile is preferably carried out by the aforementioned method of DE 100 34 694 A1 ,

As already indicated at the beginning, it is not absolutely necessary that all Participants who perform the method according to the invention, mobile are. Thus, using peer-to-peer communication, the first profile about one Exchange or the infrastructure of the network in the location area be provided while the second profile is in the location area. This means, that first profile is representative of the first participant through the switch or infrastructure provided while the second profile in a mobile subscriber who is in the location area is stored.

It is also advantageous if assigned to a subscriber Profile is at least part of a data set, and within the framework of the data exchange will, while the other part of the data set remains unpublished. Especially It is advantageous if each participant assigned his profile Specifies data yourself. This means that those published in a profile Data from participant to participant or even one and the same Participants may be different in different situations.

Conveniently, The data contained in the profile or disclosed by Templates determined. A particularly simple handling results, if the templates are predefined. For example, a template be defined for one Search profile and another template for a proposal profile. templates can but also dependent on the chosen one domain be.

The Cascading the template allows one particularly easy administration of the same.

It It is also envisaged that the content of a template will be participant specific variable is. By means of a participant-specific defined template can for a certain Application the data to be published in a profile are selected. Independently from a chosen one Application, a template can also be used regularly again, so that the repeated selection of respective data fields, the in a profile for publication are provided, unnecessary.

It is also beneficial if the profile information about a domain includes. This makes the comparison and the evaluation in terms of similarity or match faster and easier.

The Invention will be further explained with reference to the figures. It demonstrate:

1 A first embodiment of a network for carrying out the method according to the invention,

2 A second embodiment of a network for carrying out the method according to the invention,

3 A third embodiment of a network for carrying out the method according to the invention,

4 A fourth embodiment of a network for carrying out the method according to the invention,

5 a table showing different data fields that can be published in a profile, and

6 a table showing different basic data fields.

1 shows a first embodiment of a network, with which the inventive method can be performed. This has a first participant 1 , a second participant 2 on. Both participants 1 . 2 , which may be, for example, mobile terminals, such as a mobile phone or an organizer, have a data transmission interface (not shown), by means of a direct communication with another subscriber is possible. The first participant 1 and the second participant 2 Thus, if they are each in the transmission radius of the other subscriber, exchange data via a data transmission interface. At the in 1 The network shown is an ad hoc network, where the first participant 1 and the second participant 2 Are nodes of the network.

The first participant 1 is a first profile and the second participant 2 is assigned a second profile. Each profile includes one of each The number of data fields defined by the participant is defined.

In 6 is a list of basic data fields specified. Column 1 indicates the variable names of the basic data fields τ1 to τ8. The middle column contains the names of the corresponding basic data fields and the right column gives a brief description of the contents.

5 shows a data set of an embodiment of the invention. The data set comprises by way of example twelve data fields, of which in 5 in the left column the name of the respective data field (identification number, domain, name, address data 1, address data 2, profile type, title, keywords, description, costs, duration and dates), in the middle column the variable character of the data field according to 6 and in the right column a short description of the data field is given.

The profile now only allows the disclosure of part of this data, ie some of the data fields. As a result, only the profile information disclosed by one participant is available from the other participants in the locality area 3 recorded and subjected to a matchmaking process.

Preferably has each participant over one List of profile templates. It is between predefined, not changeable and distinguished by the participant defined, changeable templates. A template describes one for other participants visible section of the profile of the participant. A defined profile can be used as a superimposition of the overall data and his templates are seen. The templates provide "templates" on the overall data and grant a view only on a section of the total data.

The predefined templates can be built cascadically. The top-level Template guaranteed the highest anonymity and allows For example, only the recognition of the unique identification number. The properties of a template of a level will be attached to such templates one next inherited from the lower level, which expand or constrict the "template" accordingly.

The Template of the highest Level which discloses the mentioned identification number is for example, enough for a message dispatch. The next underlying level could be next the identification number to publish the name of a participant, so that in addition to the messaging and a chat would be possible. The next one below lying level could about that out an e-mail address.

The Number of levels in which the templates are cascaded or hierarchical are arranged, is not limited and may depend on every domain be designed.

Back to 1 Next, the method of exchanging data between the first party will be described below 1 and the second participant 2 described. It should be noted that in the locality area 3 of the 1 Of course, a larger number of participants than the two shown are possible. The steps described below are then carried out simultaneously or successively by two participants.

As soon as the first participant 1 the presence of the second participant 2 within its transmission radius (this of course also applies the other way round) becomes the first profile of the first participant 1 to the second participant 2 sent the same time his profile (the second profile) to the first participant 1 sends. More precisely, in the context of the communication, it is first checked whether the first and the second participant each have profile types which match their profile structure. Only when a match has been found, the profiles are exchanged with the aim of "matching" them with each other 1 . 2 via a computing unit that is able to compare and evaluate its own and the received profile. For this purpose, for example, in the DE 100 34 694 A1 described method used.

First, it checks whether the domains specified in the respective profiles match. For example, human resources (HR) -evaluation, project staffing, purchase / rental / exchange markets, connections at trade fairs and events, cooperation applications, contact requests, finding like-minded people, etc. may be considered domains. If there is a matching domain, the comparison process takes place, ie the matchmaking is carried out by each of the communicating parties. If the profiles match, which also includes similarity, the participants will be informed accordingly. Since a rating of the profiles takes place only between those participants who are within the locality area 3 stop, is a direct contact between the first and second participants 1 . 2 possible. The contact, which can initially consist only in the exchange of eg a telephone number or an e-mail, then allows a personal contact because of the geographical proximity of both participants.

The inventive method considered with that spatially distanced profile matches usually much more unattractive than those in which one local proximity consists. Only this gives the chance, an offer or interest to convey a sustainable offer. In addition, with immediate, local contacts the information necessary for the decision, for example in an immediate conversation, exchanged become.

2 shows a second embodiment of a network for carrying out the method according to the invention. This network is different from that 1 in that in the location area 3 an exchange 4 is provided, over which the first participant 1 and the second participant 2 communicate. The exchange 4 , which may be, for example, an access point, serves on the one hand, the extent of the location area 3 on the other hand, to increase its bandwidth. This means within the location area 3 a larger number of participants can communicate with each other at the same time. This network is - as in 1 - a peer-to-peer communication.

The same applies to the network of 3 , This embodiment is characterized in that only one participant, namely the second participant 2 in the location area 3 is located while the first participant 1 spatially separated from it at another location. However, the profile associated with the first subscriber is by means of a switching station 4 , which are also in the location area 3 located, for communication purposes for the subscriber 2 available. The first profile of the first participant 1 is thus in the switching station within the location area 3 saved, leaving the second participant 2 can make a comparison and a rating with this. If there is a corresponding match, the result is sent to the physically separated participant via an appropriate infrastructure 1 transmit, which then also a contact is possible. This variant is suitable, for example, when the first participant 1 only briefly outside the location area 3 located.

The fourth embodiment, which is in 4 for communication purposes, a so-called client-server architecture is used. There is no direct communication between the participants 1 . 2 and 7 possible, even if these (participants 1 and 2 ) in the same location area 3 are located. The communication basically takes place via the infrastructure of the network, represented by the reference numeral 5 is marked. In addition, it is characteristic of this variant that a comparison of the profiles is not made by the participants themselves, but that this comparison, eg in a computing unit, the infrastructure takes place. The arithmetic unit 6 however, only returns the result of a matching comparison to the respective participants if these are within a location range 3 are located. In the present example these are the participants 1 and 2 , The one with the reference number 7 marked third participant receives, even with matching profile with one of the participants 1 or 2 , no notification, because this is not in the location area 3 located. The location area may have been previously defined in terms of its geographical extent or may correspond to the extents that apply to a peer-to-peer network. In this case, the subscribers would be the reference number 1 and 2 are characterized, in the presence of a corresponding data transmission interface, able to communicate directly with each other.

considered the acting of the participants on supply demand markets as a process chain, so the following basic processes are run through. An offer is going through defines a first participant. A demand is made by one second participant defined. The offer of the first participant is on a marketplace, which is the current geographical location of the participant at the given time, by disclosure of his Profiles announced. In a similar way, the demand the second participant by disclosing his profile also announced in this market place. The match between offer and demand is made by the first participant and / or the second Participant or through an independent intermediary and rated. This corresponds to matchmaking. The first participant finally takes Contact the second participant (or vice versa). The first and the second participant negotiates about the ones they have formed Supply-demand relationship. The. The end of the process chain is finally the - positive or negative agreement in the matter.

The Invention allows so that personalized comparing and rating profiles in the local environment of the equipment. For effective realization, the location information of each participant must ideally continuously, but at least regularly within certain time windows reported to the system.

The methods can be implemented using ad hoc networks, eg via Bluetooth, wireless LAN or infrared interfaces, or even client-server networks, such as the existing GSM, GPRS, UMTS networks.
