  • Title: Vocabulary | UMBEL
    Descriptive info: The UMBEL Vocabulary defines three classes:.. RefConcept.. SuperType.. Qualifier.. and 38 properties (in addition to recommended use of.. external vocabularies.. , especially SKOS):.. correspondsTo.. isAbout.. isRelatedTo.. relatesToXXX.. (31 variants; see below).. isLike.. hasMapping.. hasCharacteristic.. isCharacteristicOf.. In addition, UMBEL re-uses certain properties from external vocabularies.. These classes and properties are used to instantiate the UMBEL Reference Concept ontology and are a Vocabulary in their own right for aiding the definition of other domain ontologies.. Classes.. Here are the specifications for the three UMBEL classes in the vocabulary.. Class name.. umbel:RefConcept.. Description.. Reference Concepts are a distinct subset of the more broadly understood concept such as used in the SKOS RDFS controlled vocabulary or formal concept analysis or the very general or abstract concepts common to some upper ontologies.. Reference Concepts are selected for their use as concrete, subject-related or commonly used notions for describing tangible ideas and referents in human experience and language.. Reference Concepts are classes, the members of which are nameable instances or named entities, which by definition are held as distinct from these concepts.. The UMBEL ontology is a coherently organized structure (or reference "backbone") of these Reference Concepts.. In-domain-of.. umbel:isRelatedTo, skos:prefLabel, skos:altLabel, skos:hiddenLabel, skos:definition.. In-range-of.. umbel:isAbout, umbel:correspondsTo.. Sub-class-of.. skos:Concept.. Status.. Stable.. Reference Concept Class.. umbel:SuperType.. SuperTypes are a collection of (mostly) similar Reference Concepts.. Most of the SuperType classes have been designed to be (mostly) disjoint from the other SuperType classes.. SuperTypes thus provide a higher-level of clustering and organization of Reference Concepts for use in user interfaces and for reasoning purposes.. skos:prefLabel, skos:altLabel, skos:hiddenLabel, skos:definition.. SuperType Class.. umbel:Qualifier.. The Qualifier class is a set of descriptions that indicate the method used in order to establish an isAbout or correspondsTo relationship between an UMBEL reference concept (RC) and an external entity.. This description should be complete enough to aid understanding of the nature and reliability of the "aboutness" assertion and to be usable for filtering or user interface information.. The descriptions may be literal strings or may refer to literal numeric values resulting from an automated alignment technique.. umbel:hasMapping.. Qualifier Class.. Properties.. The UMBEL predicates, and those used from external vocabularies, provide the mapping basis for the vocabulary.. Predicates (properties) are provided for all structural combinations of classes, individuals and properties.. Here are the specifications for the UMBEL properties in the vocabulary.. Property name.. umbel:correspondsTo.. The property umbel:correspondsTo is used to assert a close correspondence between an external class, named entity, individual or instance with a Reference Concept class.. umbel:correspondsTo relates the external class, named entity, individual or instance to the class through the basis of both its subject matter and intended scope.. This predicate should be used where the correspondence between the two entities is felt to be nearly equivalent to a sameAs assertion, and is reflexive, but without the full entailments of intensional class memberships.. In these cases, both entities are understood to have the same type and intended scope, but without asserting a full class-level or sameAs individual relationship.. This predicate is designed for the circumstance of aligning two different ontologies or knowledge bases based on node-level correspondences, but without entailing the actual ontological relationships and structure of the object source.. For example, the umbel:correspondsTo predicate is used to assert close correspondence between UMBEL Reference Concepts and Wikipedia categories or pages, yet without entailing the actual Wikipedia category structure.. This property asserts a different and stronger relationship than umbel:isAbout.. One practical use is to guide specific instance member determinations when, say, the native structure of the external ontology or knowledge base is to be analyzed and replaced with an UMBEL-based structure.. This property is therefore used to create a nearly equivalent assertion (however,  ...   assignments (.. umbel:relatesToOtherOrganism.. shares two SuperTypes, leading to 31 different predicates):.. Mapping Predicate.. Comments.. NaturalPhenomena.. relatesToPhenomenon.. This predicate relates an external entity to the SuperType (ST) shown.. It indicates there is a relationship to the ST of a verifiable nature, but which is undetermined as to strength or a full rdf:type relationship.. NaturalSubstances.. relatesToSubstance.. same as above.. Earthscape.. relatesToEarth.. Extraterrestrial.. relatesToHeavens.. Prokaryotes.. relatesToOtherOrganism.. ProtistsFungus.. Plants.. relatesToPlant.. Animals.. relatesToAnimal.. Diseases.. relatesToDisease.. PersonTypes.. relatesToPersonType.. Organizations.. relatesToOrganizationType..

Attributes.. relatesToAttribute.. Abstract.. relatesToAbstraction.. TopicsCategories.. relatesToTopic.. MarketsIndustries.. relatesToMarketIndustry.. Workplaces.. relatesToWorkplaces.. Listing of relatesToXXX Properties.. umbel:isLike.. The property umbel:isLike is used to assert an associative link between similar individuals who may or may not be identical, but are believed to be so.. This property is not intended as a general expression of similarity, but rather the likely but uncertain same identity of the two resources being related.. This property may be considered as an alternative to sameAs where there is not a certainty of sameness, and/or when it is desirable to assert a degree of overlap of sameness via the umbel:hasMapping reification predicate.. This property can and should be changed if the certainty of the sameness of identity is subsequently determined.. umbel:isLike has the semantics of likely identity, but where there is some uncertainty that the two resources indeed refer to the exact same individual with the same identity.. Such uncertainty can arise when, for example, common names may be used for different individuals (.. e.. g.. , John Smith).. It is appropriate to use this property when there is strong belief the two resources refer to the same individual with the same identity, but that association can not be asserted at the present time with full certitude.. Symmetric.. isLike Property.. This property is used to reify a umbel:isAbout, umbel:isRelatedTo or an umbel:isLike property assertion with a statement as to its degree of mapping or relationship between subject and object.. The hasMapping property may be expressed as a mapping percentage value, some quantitative metric value, or a qualitative descriptor characterizing the linkage degree or overlap between the two classes, predicates, individuals or datatypes.. This value might be calculated from some external utility, may be free form, or may be based on some defined listing of mapping values expressed as literals.. rdf:Statement.. hasMapping Property.. umbel:hasCharacteristic.. Type.. owl:AnnotationProperty.. The property umbel:hasCharacteristic is used to assert the relation between a Reference Concept and external properties that may be used in external ontologies to characterize, describe, or provide attributes for data records associated with that concept.. It is via this property or its inverse, umbel:isCharacteristicOf, that external data characterizations may be incorporated and modeled within a domain ontology based on the UMBEL vocabulary.. umbel:isCharacteristicOf.. hasCharacteristic Property.. The property umbel:isCharacteristicOf is used to assert the relation between a property and a Reference Concept (or its punned individual) to which it applies.. Such properties may be used in external ontologies to characterize, describe, or provide attributes for data records associated with that concept.. It is via this property or its inverse, umbel:hasCharacteristic, that external data characterizations may be incorporated and modeled within a domain ontology based on the UMBEL vocabulary.. isCharacteristicOf Property.. External Properties.. The UMBEL vocabulary re-uses several properties from external vocabularies.. Here is the list of such properties that are recommended for or used by the UMBEL Reference Concept ontology.. RDFS.. rdfs:subClassOf.. OWL.. owl:equivalentClass..

  • Title: UMBEL Graph | UMBEL
    Descriptive info: UMBEL Graph.. The core UMBEL ontology now contains about 26,000 reference concepts organized according to 33 super types.. There are more than 60,000 relationships amongst these concepts, resulting in a graph structure of very large size.. It is difficult to grasp this graph in the abstract.. Thus, using methods earlier described in our use of the.. visualization software [1], we present below a dynamic, navigable rendering of this graph of UMBEL core:.. Note.. : at standard resolution, if this graph were to be rendered in actual size, it would be larger than.. 34 feet by 34 feet square.. at full zoom !!!.. Hint:.. that is about  ...   labels, and with connections shown (though you must must zoom to see).. The color-coded relation of these nodes to the 33 or so major SuperTypes in UMBEL, as well as the relative position of these clusters with respect to one another, and.. When zooming (use scroll wheel or + icon) or panning (via mouse down moves), wait a couple of seconds to get the clearest image refresh:.. You may also want to inspect a static version of this big graph by.. downloading a PDF.. [1] See further, M.. K.. Bergman, 2011.. ".. A New Best Friend: Gephi for Large-scale Networks.. ,"..

  • Title: Web Services | UMBEL
    Descriptive info: UMBEL Web services are supported by the.. structWSF.. Web services framework.. The latest version of the UMBEL ontology has been indexed by the structWSF instance, and gets exposed to the generic public through these services.. This structWSF-UMBEL instance is made public for testing purposes only.. If you want to develop commercial applications around it, you will have to install structWSF and import UMBEL into your own instance since the performances and the up-time of this demo instance is not guaranteed.. All of the tools on this Web site are using one, or multiple, of these structWSF endpoints:.. Search.. structOntology.. Scones.. Access Information.. Here is the summary information you need to know in order to be able to query the latest version of the UMBEL ontology using the structWSF Web services endpoints.. Use this information as your parameter values when accessing the endpoints.. The permissions of the guest users are:.. Create:.. False.. Read:.. Update:.. Delete:.. These settings mean that only the Web service endpoints that require Read permissions will  ...   next, do pay special heed to the HTTP method used to query each specific endpoint:.. POST.. , or.. GET.. Web Service Endpoints.. Here is the list of the UMBEL Web service endpoints you may access.. The documentation pages for each service tells you how you to use and query each of these different structWSF endpoints:.. Ontology: Read.. Crud: Read.. SPARQL.. Note:.. the documentation for these resides on the Open Semantic Framework (OSF).. TechWiki.. Also note that not all structWSF services and endpoints are supported on this UMBEL site.. Query Examples.. Here are some example of queries you can send to these different endpoints.. These examples are using the.. cURL.. command line application to send the queries to the web service endpoints..
