Help Center: bug or user error?

2008-12-02T23:15:27.0005Z

I haven't seen this happen with the bases I've created, so I think this may be user error, but can you point us to the base in question so we can have a look?

Domains and Types: . in TLD

2008-12-02T22:57:54.0017Z

Should the TLD names really contain a dot (‘.’)? It seems to me that the TLD for the Netherlands is ‘nl’, and the dot is a separator character but not part of the TLD.

This is the first time since the new Base focus update that I've created a new base. in the Add Data area, I added all the recommended topcis/types. But now there's two of everything. Did I accidentally add things twice? Or is this a bug?

Help Center: Can I implement multiple topics with a type??

2008-11-27T03:58:07.0029Z

Yes, I did it, I've not read MQL write, but I want to add multiple topics to a type by using a MQL query. Is it possible?

Topics can be list imported to types using the import tool links that display after clicking "Add it" or "Add more" on a view. Data can be list imported to topic properties by clicking on the "Import list" button next to the property.

Hi my friends,

I want to create some new types after that I will add a group of topics or a base, for example:

I'll make type "Abstract"

so any topic adds this type then it is considered that it has the abstraction (an idea, feeling or quality, not as a material object) such as: software, human, and there are many terms have meaning like that, but I can't add each keyword manually; thus, how I can add all the topics (keywords) as I mentioned before.

Thanks u.

Help Center: Converting freebase dump to RDF

2008-11-24T20:42:44.0020Z

Rajeevpra -

Narphorium's direction with the Link Export is the easiest way to proceed.

More specifically, think of the rows in the Link Export as N-Triples (http://www.w3.org/2001/sw/RDFCore/ntriples/) where the first column is the subject, the second column is the predicate and the third column is the object (when the object is a resource, otherwise the fourth column is the literal with type info in the third column.)

Its easy to construct Freebase RDF URIs from the Link Export data. The URIs take the form http://rdf.freebase.com/ns/FREEBASE_IDENTIFIER - where the FREEBASE_IDENTIFIER is a valid Freebase ID with the slashes replaced by dots.

/guid/9202a8c04000641f8000000001100826 becomes
http://rdf.freebase.com/ns/guid.9202a8c04000641f8000000001100826

and /film/performance/actor becomes
http://rdf.freebase.com/ns/film.performance.actor

So the row in the Link Export that reads:
/guid/9202a8c04000641f8000000001100826    /film/performance/actor    /guid/9202a8c04000641f80000000000afc87

becomes the N-Triple:

<http://rdf.freebase.com/guid.9202a8c04000641f8000000001100826>    <http://rdf.freebase.com/film.performance.actor>    <http://rdf.freebase.com/guid.9202a8c04000641f80000000000afc87> .

and

/guid/9202a8c04000641f80000000000afc87    /type/object/name    /lang/fr    Steve Martin

becomes

<http://rdf.freebase.com/guid.9202a8c04000641f80000000000afc87>    <http://rdf.freebase.com/type.object.name>    "Steve Martin"@fr .

I was thinking a good Hack Day hack would have been to write a sed script to do this....but I couldn't find any collaborators. If your interested, I'd also be up for collaborator to help create/test an open source script that would do the conversion and add in some additional bells like vocabulary mapping, etc.

There is a "To" property on the "Company/Division Relationship" CVT, which was intended for this purpose.

Help Center: Is every tables in Freebase has name and id field?

2008-11-24T03:12:18.0012Z

Every Object in Freebase has an ID and a name and as far as I know all the data commons and user-generated types are objects. Compound Value Types are objects so they have IDs and names but most people don't use the name property since its not displayed in the UI.

Primitive data types like Date/Time and URI are not objects so they don't have names or IDs.

2008-11-24T01:50:56.0017Z

Hi friends,

I'm sorry if I ask you this question although I know name and id are the basic properties in Freebase. However, I want to have the certain confirmation abou that.

I forgot about the full link export. Freebase is built as a collection of links just as RDF datastores are built as a collection triples. So the link export is like a complete copy of the underlying Freebase graph.

I don't have any experience converting between Freebase links and RDF triples but you can get a good idea of how they map to one another by comparing the sample data provided on the download page with the RDF of the same topic as it appears in Freebase.

I'd also like to put in a shameless plug for my ontologies base which provides some mappings from Freebase types to common web ontologies.

This is description i found on download page:

Link Export - A full dump of Freebase assertions in a simple utf8 text format. This is a complete "low level" dump of data which is suitable for post processing into RDF or XML datasets.

So i beleive it is suitable for coversion into RDF. I have also seen some threads on different discussion boards where people has done it but i couldn't find any direct reccomendation on how to do it.

Could a property noting the year a company division was terminated (became defunct) be added? Of type Date/Time.

I don't think the data dumps are available as RDF. The data dumps that are available right now are formated as TSV files and as far as I know there is no direct relationship between those files and the linked data that Freebase provides.

Hi Guys,

I looked through data dump available from Freebase site but couldn't figure it out how to convert this into RDF. I need help in form of tool or just simple description of this format and how it relates to rdf.
