As the importance of information sharing and linking is highlighted, web services using ontology as a knowledge expression model are increasing. Recently, data model using ontology has been attracting attention in connection with research of semantic web.
Applications using the semantic web include automated communication between agents, web service automation, semantic-based search services in ubiquitous environments, and information retrieval from heterogeneous multimedia databases. However, these applications basically assume that all agents reference a common ontology. If these agents do not refer to a common ontology, such an application would be impossible. That is, since the semantic web is distributed and heterogeneous like the existing web, it is difficult to assume that all agents refer to a common ontology.
For example, if one agent refers to an ontology that describes the address of a person's home as "address", the other agent refers to an ontology that describes it as a "postal_address". Communication between them becomes impossible.
In addition, existing studies to ensure the uniformity of URI (Uniform Resource Identifier) required for linkage and utilization of semantic web data have limited types of entity identification, and do not effectively support real-time entity identification of ontology, which is gradually added. It has limitations such as using the error included in the entity identification relationship as it is.

The foregoing and other objects, features, and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.
First, the terms used in the present invention will be described.
Linked Data is a movement and code of conduct for the data network at the heart of the next generation of the Web. The goal is to open and connect data freely on the web, and to enable these data to collaborate again to realize a true data web. Therefore, HTTP (hypertext transfer protocol) is used for data distribution on the web, and Resource Description Framework (RDF) and Simple Protocol and RDF Query Language (SPARQL) are used to ensure connectivity and accessibility, which is included in the ontology. This is a standard query language used for querying collected information. It performs functions similar to the structured query language (SQL) of the database management system (DBMS).
In addition, Linked Data names specific concepts as Uniform Resource Identifiers (URIs), allows access to resources named as URIs over HTTP, and provides detailed information contained by RDF-based URIs when accessed. It provides access to other relevant concepts contained in RDF.
URIs are identifiers of classes, properties, and entities that are mapped to unique addresses on the Web to share information resources over the Web. In other words, it is an internet address and identifier used to access information of a class, property, or object through a URL. The URI is used in the term entity identifier.
Ontology is constructed by defining concepts and attributes and establishing the relationship between concepts and concepts by obtaining knowledge about the components of ontology that is to be constructed in ontology from related documents of specific field, namely concept, property of concept, connection relation between concepts. In the semantic web, concepts are represented by URIs. For example, the "Person" class is represented in the ontology as a URI such as "http://www.etri.re.kr/example#Person".
The "Person" class has properties such as name, age, birthplace, and so on. The "name" attribute can have a string as its value, the "age" attribute can have an integer as its value, and the "birthplace" attribute can have an instance of "Location" as its value. have.
Entity identification refers to the explicit establishment of a relationship to a URI in order to ensure that the classes, properties, and entities that make up the ontology are interrelated. For example, if the A-1 entity of ontology A is the same as the B-1 entity of ontology B, you can merge A-1 and B-1 related properties by specifying that the A-1 and B-1 entities have the same relationship.

The
4 is a flowchart illustrating a method of searching for and providing an object identification result by an object identification result search apparatus according to the present invention, and FIG. 6 is an exemplary view showing an object identification result search screen according to the present invention.
Referring to FIG. 4, when the query by the entity name or the entity identifier (URI) is input (S402), the apparatus for recognizing the entity identification result determines whether an identification result for the input query word exists in the triple storage module. (S404). The triple storage module stores the entity identification result expressed in ontology, and the entity identification result retrieval apparatus uses a new entity name or a new entity identifier (ID) based on whether an identification result of the query word exists in the triple storage module. Determine whether or not URI) is input.
As a result of the determination in S404, when the identification result for the query word exists in the triple storage module, the entity identification result retrieval device obtains the identification result for the query word from the multiple ontology database (S406). That is, the individual identification result retrieval apparatus obtains the identification result for the query using Sindice.com, sameAs.org, and the like. The identification result for the query word refers to a list of entity identifiers of entities related to the query word.
After performing S406, the object identification result retrieval apparatus compares the identification result of the query word obtained from the triple storage module with the identification result of the query word obtained from the multiple ontology database (S408). It is determined whether the list of identifiers is the same (S410). That is, the entity identification result retrieval apparatus compares the entity identifier list according to the identification result from the triple storage module with the entity identifier list based on the identification result from the multiple ontology database, and compares the entity identifier list to the entity identifier list from the multiple ontology database. Determine whether a new entity identifier is included.
If the two lists are the same as the determination result of S410, the entity identification result search apparatus visualizes the identification result for the query word obtained from the triple storage module (S412). The identification result of the query word is entity identifier group summary information indicating summary information of all groups in which the query word is used, and the entity identifier group summary information includes the number of entity identifiers, entity types, representative entity names and representative entity identifiers of the group. Include. That is, the entity identification result retrieval apparatus includes at least one of a query input region, an external database association command, an entity identifier group summary list, an entity identifier group summary graph, a detailed entity identifier list for each group, an identification command, and an editing command. Outputs the screen for providing the object identification result.
When the user edits the visualized entity identification result (S414), the entity identification result search apparatus stores the edit result in the triple storage module (S416). That is, when the user edits at least one of the modification, deletion, and movement of the entity identification result, the entity identification result search apparatus stores and updates the edit result as the entity identification result in the triple storage module. do.
Referring to FIG. 6 for the entity identification result providing screen, the entity identification result providing screen includes a query entry area for inputting an entity identifier or a query name of an entity, an entity in which entity identifier group summary information for the query is displayed in a list and a graph. An identifier group summary information providing area, and a detailed entity identifier list providing area where a detailed entity identifier list for each entity identifier group is provided.
There is a command for linking with an external service in the query input region.
The entity identifier group summary information providing area includes an identification command selected when the entity identification using the updated information is desired in the triple storage module and an editing command for editing the entity identifier group information.
Select the edit command to edit the representative entity name or representative entity identifier of the entity identifier group, merge different groups or divide one group into different groups, and move entity identifiers belonging to a specific group to another group. Can be performed. When the user modifies the representative entity name and the representative entity identifier of the entity identifier group, the entity identification result retrieval apparatus maintains the representative entity identifier and the representative entity name modified by the user even if the statistics of the group are subsequently adjusted. This adjusted result is also used later in the identification process.
In addition, the user may move or delete an object identifier belonging to a specific group to another group by using an editing command. The edited result as described above is stored in the triple storage module again and later reflected in the entity identification process.
When a specific object identifier list is selected in the detailed object identifier list providing area, the object identification result retrieving device outputs a verification result for the object identification to a predetermined area of the object identification result providing screen. That is, the verification result shows a correlation between the various attributes used to identify the object in a graph, and the user can confirm the object identification result through the graph.
In addition, when the individual entity identifier is selected in the detailed entity identifier list providing area, the entity identification result retrieval device also provides a function of identifying related attributes through the SPARQL endpoint service provided by the ontology.
If the two lists are not the same as the result of the determination in S410, the entity identification result retrieval apparatus identifies the entity by acquiring and comparing the attribute information of the entity identifier with the new entity identifier as an object of identification, and by the entity identification, An entity identifier group for the query is generated (S418). That is, when a new entity name or a new entity identifier exists, the entity identification apparatus acquires attribute information of the new entity identifier for the multiple ontology database, and identifies the entity using the acquired attribute information. When an entity is identified as above, entity identifier groups containing new entity identifiers are created. The above object identification process is not performed on every object identifier every time, but on an object identifier that contains an updated object identifier from the list of object identifiers collected through a user's query or does not go through the object identification process. do. A detailed description of how the entity identification result retrieval apparatus identifies the entity will be described with reference to FIG. 5.
When S418 is performed, the entity identification result search apparatus updates the triple storage module by selecting a representative entity identifier or a representative entity name for each entity identifier group generated through the entity identification (S420). That is, the entity identification result retrieval apparatus selects a representative entity identifier and a representative entity name of each group by using an entity identifier belonging to each group and a statistical value of the entity name for the entity identifier group on which the entity identification is completed.
After performing the S420, the object identification result search apparatus obtains and visualizes the information on the updated object identification result from the triple storage module (S422), and performs the S414.
If the identification result of the query word does not exist in the triple storage module as a result of the determination in S404, the entity identification result retrieval apparatus obtains and visualizes the identification result of the query word from the multiple ontology database (S424). .
5 is a flowchart illustrating a method for identifying an entity by the entity identification result retrieval apparatus according to the present invention.
Referring to FIG. 5, the apparatus for recognizing an entity identification result acquires attribute information of a new entity identifier to be identified from a multiple ontology database (S502), and uses the attribute representing a type in the acquired attribute information according to the entity type. A group is assigned to the entity identifier (S504). That is, the object identification result retrieval apparatus checks the property that can distinguish the type of the object through the parent-child relationship between the rdf: type or the explicit type class among the property information of the new object identifier, and checks the identified object type. Assign the new entity identifier.
For example, referring to Table 1, if a subclass of foaf: person exists, the subclass can be determined to be a class meaning a lifespan. That is, if kisti: person, class 1 belonging to Ontology A, is a subclass of foaf: person, the object identification result retrieval device determines the type of the object later by identifying and storing that kisti: person is the object type corresponding to the person. Used for
When the S504 is performed, the entity identification result retrieval apparatus loads the same attribute mapping information and the representative attribute for each group grouped according to the entity type in the attribute information table (S506). That is, the object identification result retrieval apparatus may use the same attribute mapping information (e.g., kisti: hasCreator and foaf: maker are the same attribute) and representative attributes (e.g. human The representative attribute of is loaded with “foaf: name” attribute in foaf ontology.
When S506 is performed, the entity identification result retrieval apparatus regroups the groups grouped by the entity type based on the representative attribute (S508). That is, the entity identification result retrieval device calculates the similarity of the string corresponding to the attribute value based on the representative attribute name of the entity identifier for each entity type, and groups the entity identifiers having the predetermined similarity greater than or equal to a predetermined threshold value into the same group. .
For example, in the case of people, the similarity is calculated for the human name and in the case of the company, and grouped using the calculated result. In this case, we use the Jaro Winkler Distance string comparison method, which is suitable for short string comparisons.
In addition, the entity identification result retrieval apparatus forms the representative attribute names in a predetermined format according to a predetermined rule, and then groups them through similarity calculation. For example, in the case of human names, the similarity is calculated through string comparison considering the First Name, Middle Name, and Last Name.
In addition, in the case of the institution name, similarity is calculated through string comparisons considering notation names such as ".inc", "co", and "INC".
After performing the step S508, the entity identification result retrieval apparatus obtains and compares the associated attribute values of the entity identifiers belonging to each group from the multiple ontology database and divides each group into subgroups based on the comparison result. The entity identifier group for the is determined (S510).
That is, the entity identification result retrieval apparatus obtains an association attribute value for an entity identifier belonging to each group from the multiple ontology database and checks whether entity identifiers having the same association attribute value exist. If there are entity identifiers having the same attribute value as the result of the checking, the entity identification result retrieval apparatus determines the entity identifier group for the query by dividing the entity identifiers having the same attribute value into subgroups.
Through this process, the entity identification result retrieval device may identify entity identifiers classified into different groups or entity identifiers classified into different groups or entity identifiers having the same group but no mapping property in the process of grouping the entity identifiers based on the previous entity type or entity name. .
That is, when the representative attributes are mapped to the same association attribute value A of the entity identifiers 1 and 2 belonging to different groups, the entity identification result retrieval device obtains the association attribute value of A so that the entity identifiers 1 and 2 are both Check if it is included as an association property.
For example, if the individual identifiers 1 and 2 are different author names, but all have the author relationship of the A paper, the individual identification result retrieval apparatus collects the association attributes of the A paper, and the individual identifiers 1 and 2 are all the author relationship. Check that it is connected.
When the S510 is performed, the object identification result retrieval apparatus repeats the steps S502 to S510 to verify the object identification result and finalizes the object identifier group (S512).
Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the embodiments described above are to be considered in all respects only as illustrative and not restrictive.
