freebase

I am new to Freebase and I have been trying to find relationships between 2 nodes without success. For example, I want to find if there is link between Lewis Hamilton(/en/lewis_hamilton) and Formula One(/en/formula_one), which there is in real life, but I can't seem to find it. I have tried the following MQL codes, alternating IDs as well : 1) [{ "type" : "/type/link", "source" : { "id" : "/en/lewis_hamilton" }, "master_property" : null, "target" : { "id" : "/en/formula_one" }, "target_value" : null }] 2) { "id":"/en/lewis_hamilton", "/type/reflect/any_master":[{ "link":null, "name":null }], "

Freebase WEX dumps contain a wpid column corresponding to the page_id from the source MediaWiki database in the freebase_wpid table. This table provides a mapping between Wikipedia numeric article/redirect IDs and Freebase GUIDs (Global Unique IDs). guid use as foreign keys is deprecated by mid for lots of good reasons , but that doesn't change the fact that guids are still used at a system level so I'm going to call mid an accessor from here on. Using the mid accessor is flexible in MQL. One can query using "mid": null and using "mid":[] depending on whether one needs the current mid or every

I just want to get from Freebase the different aliases a person can have. My PHP query is : $query = array( array( 'id' => NULL, 'alias' => NULL, 'name' => "Barack Obama", 'type' => "/people/person" ) ); The result is: Array ( [code] => /api/status/error [messages] => Array ( [0] => Array ( [code] => /api/status/error/mql/type [info] => Array ( [expected_type] => /people/person [property] => alias ) [message] => Type /people/person does not have property alias [path] => [query] => Array ( [0] => Array ( [alias] => [error_inside] => . [id] => [name] => Barack Obama [type] => /people/person ) )

Does anyone know the best way of getting Actor Ids from Freebase data dumps, and later on getting the IMDB ids and biographies from the Freebase API? Actors will have the type /film/actor and look like this in the dump: ns:m.010q36 rdf:type ns:film.actor. You can find them all in a few minutes from the compressed dump with a simple grep: zgrep $'rdf:type\tns:film.actor.' freebase-rdf-<date of dump>.gz | cut -f 1 | cut -d ':' -f 2 > actor-mids.txt This will generate a list of MIDs in the form m.010q36 which represents the MID /m/010q36 . Using the list of MIDs, look for all lines which have

I am trying to get a list of results from Freebase. I have an array of MIDs. Can someone explain how I would structure the query and pass it to the API in PHP? I'm new to MQL - I can't even seem to get the example to work: $simplequery = array('id'=>'/topic/en/philip_k_dick', '/film/writer/film'=>array()); $jsonquerystr = json_encode($simplequery); // The Freebase API requires a query envelope (which allows you to run multiple queries simultaneously) so we need to wrap our original, simplequery structure in two more arrays before we can pass it to the API: $queryarray = array('q1'=>array(
