![]() One can say “Alice ‘married to’ John”, and add a “‘as of’ Dec 17, 1994” property to the ‘married to’ component. Property graph databases allow the property part to be referenced directly to attach other properties. ![]() RDF graphs cannot add information directly to the predicate part of a triple, they can only add information to a triple as a whole. ” ‘ left lung‘ ‘ in_left_side_of‘ some ‘ pair of lungs‘”).Ī note for those reusing ontology content in a “Property Graph Database” like Neo4j: these have different and powerful but relatively non-standardized technical framework (in other words, different querying languages) in comparison to the RDF standard. ” ‘ left lung‘ subClassOf lung“) and other relations that can exist between terms (e.g. These triples enable descriptions of term hierarchies, (e.g. Technically, this is achieved by describing each piece of information as a subject-predicate-object triple, where the subject is some entity, and the object is some other entity or piece of information like text or a number. The RDF format is used to detail the hierarchy and attributes of ontology terms. IntroductionĪn OWL ontology is often provided in the Resource Description Format ( RDF) which can be queried as an RDF graph using the SPARQL query language. This use case is detailed below, and culminates in the new foodon_synonyms.tsv file which is updated regularly on the FoodOn github repository. For reuse in tabular databases, the easiest way to extract the hierarchic ontology terms is to convert them into a flat table indicating term id, its parent, and associate info. ![]() To learn more, see the privacy policy.Ontologies can provide the standardized vocabulary to populate both graph databases and traditional tabular database content fields containing categorical selections (e.g. Please note that Urban Thesaurus uses third party scripts (such as Google Analytics and advertisements) which use cookies. Special thanks to the contributors of the open-source code that was used in this project: and you might like to check out the growing collection of curated slang words for different topics over at Slangpedia. There is still lots of work to be done to get this slang thesaurus to give consistently good results, but I think it's at the stage where it could be useful to people, which is why I released it. Please also note that due to the nature of the internet (and especially UD), there will often be many terrible and offensive terms in the results. Or you might try boyfriend or girlfriend to get words that can mean either one of these (e.g. ![]() The search algorithm handles phrases and strings of words quite well, so for example if you want words that are related to lol and rofl you can type in lol rofl and it should give you a pile of related slang terms. The higher the terms are in the list, the more likely that they're relevant to the word or phrase that you searched for. Note that this thesaurus is not in any way affiliated with Urban Dictionary.ĭue to the way the algorithm works, the thesaurus gives you mostly related slang words, rather than exact synonyms. The official Urban Dictionary API is used to show the hover-definitions. These indexes are then used to find usage correlations between slang terms. The Urban Thesaurus was created by indexing millions of different slang terms which are defined on sites like Urban Dictionary.
