Vocabulary for Search Results

Hi, I am looking for an RDF vocabulary to represent result lists of search requests. It should be able to represent an ordered list of result items, optionally with a score, where each result item points to a separate RDF resource. So far I didn't manage to find a suitable vocabulary, so I'd be

SPARQL: restricting DESCRIBE queries

Hi, is there any way to limit the number of triples returned by a DESCRIBE query? The LIMIT clause of sparql obviously applies to the number of result bindings, but each result binding may lead to an arbitrary number of triples. Consider the following queries against dbpedia: SELECT ?con

Hi, Unfortunately, I want to employ an RDFS reasoner AND use the foaf:holdsAccount to point to /non/Online Accounts. I can't use it because my /non/online Accounts WILL be interpreted as foaf:OnlineAccounts, which I want to be satisfiably false (but is provably true). Clearly. To fix th

Re: Visualization of domain and range

Dan, Yeah, my [4] is at my threshold of tolerance for chaos in a diagram. I wanted a way to show the core of the FOAF spec in a picture, so tried (despite similar concerns to those mentioned in this thread) the style of putting domain/range directly in an instance-like style. I think this

Mark, And everyone knows at least one way to publish HTML, don't they? I disagree. Most people know how to enter text into a form, but they have no clue what HTML is all about, how it comes that one line of text is bigger while the other is smaller, how backlinks and permalinks are creat

Re: Visualization of domain and range

Toby, http://buzzword.org.uk/2009/domain-range-illustration.png It would be even better to flip it so that the ontology level is on top of the instance level, so to be in line with MOF. You're right, it's much clearer this way: http://buzzword.org.uk/2009/domain-range-illustration-flipped.p

Re: Visualization of domain and range

However many "newbies" to RDF and ontologies are confused by this, because the triple foaf:Agent foaf:holdsAccount foaf:OnlineAccount . is actually not contained in the ontology. What needs to be communicated is that: [ a foaf:Agent ] foaf:holdsAccount [ a foaf:OnlineAccount ] . instead. Tho

Brian, I think you're "better" graphic has an extra rdf:domain where an rdf:range should be. many thanks, fixed that. This shows again how careful one has to be when it comes to visualization ;-) Best, Bernhard

Visualization of domain and range

Hi, a couple of times now I ran into misunderstandings by students regarding a common visualization style of property domain/range relationships in ontologies. Actually, it is quite common to draw diagrams of ontologies in a style similar to ER diagrams, where classes are represented as e

Re: Granular dereferencing ( prop by prop ) using REST + LinkedData; Ideas?

Hi Yves, Indeed, that's a bad example - replace it by "find here persons born in NYC and their birth date". It is easy enough to find examples that involve more than just one property in the target document, e.g. "Find here female scientists born in NYC", "Find here the phone numbers of the Tab

existing skos:prefLabel for this? Also, the SKOS extension for labelling (XL) may be a good starting point for this; this vocabulary already allows one to define different labels and also model relationships between them. <http://www.w3.org/TR/skos-reference/#L4945> Best, Bernhard -- Be
