My next mistake - focussing entirely on the data provider

Linked Open Data by example

Asking a question of the British Museum’s Linked Open Data interface

The RDF triple

subject(uri)

object(uri, literal)

More complex SPARQL

SELECT ?s { ?s bmo:PX_object_type ?objecttype. ?objecttype skos:prefLabel "sarcophagus". ?s ecrm:P45_consists_of ?material. ?material skos:prefLabel "granodiorite"} LIMIT 100

1. What does it mean to be a researcher in the new Big Data archaeological research environment?

2. What tools are we now to use and are these radically different to those used by our forebears?

3. Are the types of questions that we are now asking in some way different?

4. How much creative and/or intellectual authority will we cede to the control of machines out of necessity or choice?

5. All of these questions combine to ultimately ask whether we need to be talking in terms of new epistemological environments when considering Big Data research or not?

Parting questions
