Definitions
- the present invention relates to a system and method for data adaptation in the context of a data transmission between a transmitter and a receiver that do not share the same syntactical definition of these data.
- the invention applies in particular in the context of communicating systems consisting of software applications that exchange messages between them.
- a software application connected to a heterogeneous communication network communicates in most cases with another remote application via messages containing data.
- These messages can have the same semantic nature, that is to say convey the same content, but present a syntax or schema of the different data structure.
- a message that defines a mailing address can be generated by a first application in the form of a single data structure containing the following fields: an integer specifying a street number, an enumerator specifying a street type, a string of characters specifying a street name, an integer specifying a postal code, a string of characters specifying a city and a string of characters specifying a country.
- This same message defining the same postal address can be generated by a second application with a different syntax, for example a first data structure indicating the city and containing the postal code, the name of the city and the name of the country in the form of chains. of characters and a second data structure indicating the street and containing its number, type and name specified as strings.
- a first data structure indicating the city and containing the postal code
- a second data structure indicating the street and containing its number, type and name specified as strings.
- the semantic contents of the two messages are identical but their syntax is different which causes problems of interoperability between applications.
- the problem that the present invention seeks to solve is notably to allow the exchange of data between several applications without, however, sharing the same data schema or the same syntax.
- the invention proposes, in order to solve the problem previously introduced, a data adaptation method for dynamically transforming an original non-hierarchical data format into a structured data format used by a target with which one seeks to communicate.
- the non-hierarchical data format expression refers to a set of data of various types put end to end to form a message without a particular structure.
- the method and the system according to the invention are based on the use of a knowledge base or ontology in which a set of semantic concepts is defined.
- the invention has the following advantages: the use of an ontology as a basis for common knowledge makes it possible to be more complete than a lexicon, thanks in particular to the relations that exist between two semantic concepts such as, for example, the relationship of 'equivalence.
- the abandonment of the pivot format makes it possible to significantly reduce the calculation time.
- the invention relates to a data adaptation system comprising at least one transmitter executing at least one calling application and a receiver executing at least one called application, the transmitters and receivers being interconnected via a communication network, said calling application generating messages intended for said called application, said messages being structured according to a first syntax SA, said called application being adapted to receive messages structured according to a second syntax S B , said system being characterized in that it comprises a knowledge base ontological and a directory of common services to transmitters and receivers, said adaptation system further comprising a translation module connected to said database and said directory adapted to carry out a direct translation of said messages according to the second syntax SB-
- said ontological knowledge base defines a set of semantic specifications of the data exchanged between the transmitters and the receivers. of said system, said specifications being formalized by semantic concepts linked together by dependency relations, said translation module being adapted to exploit the content of said database in order to match the semantic specifications of the structured message according to the syntax SA with those of the structured message according to the syntax S B so that said messages have the same semantic content.
- the translation module is, in addition, adapted to exploit the relationships between semantic concepts defined in the ontological knowledge base to widen the correspondence searches between the semantic specifications of messages structured according to two syntaxes S A , SB different.
- the service directory contains all the syntaxes S A , S B associated with the applications executed by the transmitters and receivers of said system.
- the syntax S A of the calling application is defined as the sequence of a set of data without a particular structure or specific order.
- the semantic specifications contained in the ontological knowledge base are defined using the definition language "Resource Description Framework” or the definition language “Web Ontology Language”
- the syntaxes S A , S B contained in the service directory are defined using the description language IDL "Interface Description Language” or the description language XSD "XML Schema Description” or by a diagram defined in the LJML language "Unified Modeling Language”.
- said translation module is specific to each transmitter or is common to all the applications executed by the transmitters and receivers of said system and centralized in a software bus.
- the invention also relates to a data adaptation method in a system comprising at least one transmitter executing at least one calling application and a receiver executing at least one called application, the transmitters and receivers being interconnected via a communication network, said calling application generating at least one message destined for said called application, said message being structured according to a first syntax S A , said called application being adapted to receive at least one structured message according to a second syntax S B , said method being characterized in it includes at least the following steps:
- a step of determining the syntax S B associated with the application called from its identifier a step of direct translation of said message in a format adapted to the syntax S B but having the same semantic content as the initial message, from the correspondence between the semantic specifications of the syntax S A and those of the syntax S B ,> a step of transmitting said transformed message to the called application via said communication network.
- FIG. 1 is a diagram illustrating an embodiment of the data adaptation system according to the invention
- FIG. 2 is a diagram illustrating the steps implemented during the transmission of a source data message to a target having a data structure schema of its own
- FIG. 1 represents an exemplary embodiment of the data adaptation system according to the invention.
- Data transmitters 101, 102 and data receivers 11 1, 12.1 13 are connected together through a communication network 150. These transmitters and receivers are, for example, computer terminals which can support both the transmitter and receiver function or only one of them.
- Each transmitter 101, 102 executes at least one calling application 131, 132 which exchanges messages 181, 182 with a called application 141, 142, 143 executed on data receiving terminals 11.1, 112.1 13.
- These messages comprise a set of data represented according to a particular syntax S A , that is to say a structure for presenting their content as well as a type associated with each of the data. This syntax is specific to each calling application 131, 132.
- an application called 141, 142, 143 also has a particular syntax S B for representing the data messages it uses.
- the two calling syntaxes S A and called S B may be different, which raises the problem of interoperability when exchanging messages between two applications.
- each sending terminal 101, 102 also executes a translation module 120 whose function is translate the message to be sent in the syntax S B of the called application.
- This translation module 120 is, for example, a local library and specific to each application 131, 132 but can also be shared by several applications, in the latter case, the translation module 120 is centralized in a software bus that is used, in particular, to communicate several systems that are not interoperable, for example because they do not use the same communication protocols.
- the translation module 120 is furthermore connected to an ontological knowledge base 160 as well as to a service directory 170.
- the service directory 170 encompasses the set of syntax definitions, also called interfaces, of messages used. by all applications or services 131, 132,141, 142,143 participants. For this purpose, each new application that registers in the system according to the invention must communicate to the service directory 170 the syntax that it uses.
- the syntax can be defined using known description languages such as IDL ("Interface Description Language”), XSD ("XML Schema Description”) or a UML (Unified Modeling Language) diagram.
- the ontological knowledge base or ontology 160 contains all the semantic specifications necessary for the explanation of a domain of knowledge. Examples of such areas of knowledge are health, security applications or e-government.
- Ontology 160 includes, for each domain of knowledge that it processes, a data model comprising a set of concepts related to each other by semantic relations. These relationships are defined, for example, using a semantic specification language such as RDF ("Resource Description Framework") or OWL ("Web Ontology Language").
- RDF Resource Description Framework
- OWL Web Ontology Language
- Each concept corresponds to a semantic specification and can also include one or more instances, that is, elements belonging to this concept.
- the term semantic specification defines the set of information associated with a datum that makes it possible to specify its meaning in the contours of a particular domain.
- the ontology 160 is, for example, developed by experts working in the fields concerned by the applications 131, 132, 141, 142, 143, then standardized so that it can be shared by all the participating applications.
- An ontology 160 differs in particular from a conventional database in that it makes it possible to reasoning about concepts.
- An ontology associated for example with an inference engine, allows to automate the creation of new relations between the concepts by deduction on the definitions of the initial relations between concepts.
- the ontology 160 and the service directory 170 are preferably centralized and accessible by the transmitting and receiving terminals 101, 102.1, 112.1 through the network 150.
- the ontology 160 and the service directory 170 can be duplicated on each terminal if it has sufficient resources in terms of available memory for storing the two 160,170 bases.
- This embodiment has the advantage of avoiding data exchanges across the network 150 between the applications, the ontological base 160 and the service directory 170. This then involves setting up a system for synchronizing the databases. knowledge 160 between them as well as directories of services 170 between them.
- FIG. 2 illustrates the steps implemented by the invention for adapting the syntax of the messages transmitted from a calling application 131 to a called application.
- the application 131 executed on the terminal 101 tries to transmit a data message 202a to a user.
- remote application 141 with which it communicates via the network 150.
- the transmission of a message 202a is, for example, during the call by the application 131 of a function executed by the application 141 called remote .
- the calling application 131 transmits the message 202a with a syntax S A specific to the translation module 120 or in a non-hierarchical format directly.
- This syntax S A is for example defined using the Extensible Markup Language (XML). It also transmits a means 203 for identifying the called application 141.
- XML Extensible Markup Language
- This means 203 is, for example, the address of the receiver terminal 11 on the network 150 associated with a service identifier provided by the called application 141.
- the calling application 131 transmits to the software bus an identifier of the service with which it wishes to communicate and the software bus is responsible determine the address of the receiver terminal 1 1 1 that hosts this service.
- the translation module 120 transforms the message 202a in order to give it a simple structure with a single level of depth, that is to say that all the elements composing this message are put end to end without specific order in order to obtain a non-hierarchical data structure.
- This transformation is optional in the sense that the calling application 131 can directly transmit the message 202a in a non-hierarchical format.
- the translation module 120 sends a request 210a to interrogate the service directory 170 by communicating the identifier 203 to know the syntax S B that uses the called application 141.
- the service directory 170 transmits it 210b then the SB syntax required to generate the skeleton of the 202b message format adapted to be interpreted by the called application 141.
- This syntax S B uses, for example, different levels of depth and various types of data to structure the elements of a message. All the elements defined by the syntaxes used by the participating applications 101, 1 1 1 are semantically specified and all the semantic concepts come from the ontology 160 which is shared by all the applications 101, 1 1 1.
- the calling application 131 communicates directly with the service directory 170 in order to retrieve the syntax SB of the called application 141 and then communicates this syntax to the translation module 120.
- the translation module 120 sends a request 220a to the ontological knowledge base 160 so that it transmits to it 220b the semantic concepts associated with the elements that form the content of the data message 202a. From these semantic concepts, the translation module 120 establishes a correspondence between the semantic specifications of the data of the initial message 202a and those associated with the syntax S B. The translation module then generates the elements of the message 202b which have the same interpretation. semantics but which are structured according to the syntax S B which allows the called application 141 to process this message. Once generated, the message 202b is transmitted to a transmission infrastructure 201 which transmits the message to the remote application 141 via a reception infrastructure 21 1.
- the translation module 120 uses the relations between semantic concepts in the knowledge base 160 to expand matching searches.
- FIG. 3 schematizes the operation of an ontology comprising several concepts related by relations during the adaptation according to the invention of data structured in a first format to a second format.
- the ontology under consideration contains several concepts used to semantically specify a client from several attributes.
- the ontology includes in particular the concepts of person 301 and client 302 interconnected by the relation "is a" 311.
- the concepts of person 301 or client 302 are related by composition or aggregation relationships to the concepts of name. of family 303, first name 304, age 305 and sport 306.
- the input message 321 of the adaptation method according to the invention is for example written in XML and contains a certain amount of data enabling identification. a particular customer.
- the semantic content of this message 321 corresponds to the person Martin Dupont whose age is 18 years old and the sport practiced is swimming.
- This message 321 has a non-hierarchical data format, that is to say that the subjects name, surname, age and sport are listed successively without any particular structure, they are also specified in French.
- the format of the output message 323 of the method is different on the one hand because the fields specified in this message are written in English and a structural separation is performed between the fields "firstname” (English first name translation) and "surname” (translation) English name) that define a first level of semantic specification of the content of this message and other fields such as the age of the client that are stored in a structure labeled "other_info".
- the overall structure of the message relates to the concept of client 303 while that of the input message 321 relates to the concept of person 301.
- the method according to the invention makes a transformation 322 of the input message 321 to the message of output 323 whose semantic contents are identical by exploiting the relations between concepts of the ontology.
- the data is rearranged in the correct order and respecting the target structure.
- the method exploits the semantic relationship "is a" 31 1 between the concepts 301 and 303 to match the data fields of the same semantic content of the two messages 321, 323.
- Finally the unused data, for example those corresponding to the sport 306 are not taken into account in the output message 323.
- FIG. 4 schematizes a second example illustrating the method according to the invention.
- the same ontology is considered by adding the concept of full name 401 which is related to the concepts of last name 308 and first name 304 through the semantic relation "is composed of" 41 1.
- the input message 421 includes the surname 303 of the person, in the example Dupont and his first name 304 Martin.
- the structure of the output message 423 presents a single data field associated with the concept 401 full name which groups the first and last name into a single data item.
- the transformation 422 operated exploits both the relation 31 1 "is one" and the relation 411 "is composed of” to generate the composite data Martin Dupont in the output message 423.
- FIG. 5 schematizes a third example illustrating the method according to the invention.
- the input message 521 contains the semantic definition of several people 301, namely Martin Dupont and Jean Dubois.
- the method according to the invention makes it possible to define a set of non-ordered elements which will not be dissociated during the adaptation of data. This notion is particularly necessary for the management of types such as a list, a table, a collection. This notion makes it possible, while exploiting the semantic relations 311, 41 1 between concepts of the ontology, not to dissociate two initially associated data such as the name and the first name of a person.
- the method according to the invention generates 522 an output message 523 containing the composite names Jean Dubois and Martin Dupont and not Jean Dupont and Martin Dubois as would be possible if no notion of set ordered was specified.
