2 | For detailed example and screenshots see RDF Export example 3 |
4 | 5 |6 | With the export functionality, you can determine the intended structure of the RDF data by drawing a template graph. The exporter iterates through the project rows, evaluate expressions in the template graph and produce an equivalent RDF subgraph per row. The final result is the merge of all the subgraphs. 7 |
8 |9 | The image below shows the main parts of a graph template. 10 |
11 |
12 | 
13 |
15 | Any applied filters on the data affect the exported RDF (i.e. RDF data exported corresponds to the current visible rows). This allows getting RDF data for any custom subset of the data or using different schemas for different parts of the data. 16 |
17 |18 | Notice that you can define multiple trees (i.e. multiple root nodes) as shown in the figure above. 19 |
20 |21 | Terms from existing vocabularies can be imported. The exporter attempts to retrieve and index the terms so that they can be included in the autocompletion available for classes and properties addition. Additionally, by using a dump from -our lovely friend- prefix.cc URIs for popular prefixes are automatically suggested. 22 | 23 |
24 |25 | Data can be exported in RDF/XML or Turtle using the "Export" menu. 26 |
-------------------------------------------------------------------------------- /website/content/rdf-export.html: -------------------------------------------------------------------------------- 1 | This is a simple example showing how RDF can be extracted from a sample CSV file (you can download the whole project and then directly import it in Google Refine) 2 | 3 |-

5 | Create a Google Refine project based on the highest-earning senior civil servants in UK as published by the Cabinet Office on 1 June 2010.
6 | The first few lines of the sample CSV file is shown in the figure below.
7 |
8 |
10 |
9 | 11 | The intended RDF we want to export should look like (for the first line): 12 |
13 |
26 | 27 |14 | <http://lab.linkeddata.deri.ie/person/0> 15 | a foaf:Person ; 16 | foaf:name "Stephan Wilcke" ; 17 | foaf:title "Chief Executive Officer"@en . 18 | <http://lab.linkeddata.deri.ie/annualPayRate> "150,000 - 154,999" . 19 | 20 | <http://lab.linkeddata.deri.ie/organization/asset-protection-agency> 21 | a foaf:Organization ; 22 | foaf:name "Asset Protection Agency"@en . 23 | foaf:member <http://lab.linkeddata.deri.ie/person/0> ; 24 |25 |

29 | Using Edit RDF Skeleton... command available under the RDF menu, we design the following skeleton:
30 |
31 |
33 |
32 | -
34 |
- we set the base URI at the top of the dialog to http://lab.linkeddata.deri.ie/test/
35 |
- Prefixs can be managed by the Add Prefix and Manage vocabularies
36 |
- We created the skeleton by repeatedly using add rdf:type and add property
37 |
- We created a new property annualPayRate which will be defined within the default namespace specified by the base URI
38 |
40 | The figure below shows an example of a node dialog (the organization URI node) 41 |
42 |44 | 45 |
43 | 46 | Notice the custom expression used to define the URI. The preview/edit shows sample values of the first 10 rows as shown below 47 |51 |48 |

53 | Saving the skeleton by clicking OK. Notice that a "Save RDF schema skeleton" operation is added to the history panel of Google Refine. As other operation, this can be undone/redone and exported/re-applied.

2 | Reconciliation is identifying multiple representations of the same real-world object. In the Semantic Web field, it is usually known as instance matching and refers to identifying equivalent resources in two RDF datasets. 3 |
4 |Reconciliation in Google Refine
5 |6 | Google Refine can reconcile values in a specific column to entities in Freebase. Reconciliation to Freebase is a very useful operation as it helps mapping ambiguous textual values to precisely identified Freebase entities. 7 |
8 | Upon reconciliation request, Google Refine starts by invoking the Freebase reconciliation service with a sample set of data values. It uses the result to guess a type for the values in the corresponding column. 9 |
10 |11 | The list of guessed types are presented to the user who can select a specific type or continue without choosing any. The user can also choose to include additional properties in the request to help enhancing the precision of the reconciliation process. Additional properties need to be clearly identified to the reconciliation service i.e. via IDs understandable by the service. To help the user in that a reconciliation service can support autocomplete for properties search. 12 |
13 |14 | Figure below shows a screenshot of the reconciliation interface resulting from reconciling a set of city names against Freebase. 15 |
16 |
17 | 18 |
19 | In the Figure we see that a set of types are suggested with City/Town/Village (with ID /location/citytown) at the top of the list. The right part of the figure shows property autocompletion in action. Proceeding with reconciliation as shown in the figure means that the set of values will be reconciled against Freebase
20 | for entities of type /location/citytown taken into account that the city is contained by a location matching the corresponding content of the state column in the data.
21 |
23 | After receiving the response, the top three matching candidates for each value are presented to the user. the user can then choose to accept one of them or refuse them all. To better inform the user decision, a resource preview is available per candidate where basic information about the candidate is provided. Additionally, a numeric facet is built based on the scores of results provided by the service, helping the 24 | user to find an acceptable threshold for the score and mass accept or reject certain results. 25 |
26 |27 | Figure below shows a screenshot where a preview for the candidate labeled "Cambridge" is presented. Results marked as an "exact match" will be automatically accepted by Google Refine without the need of 28 | user intervention. 29 |

4 |A server hosting a full installation of a Neologism site requires at least 80MB of disk space assuming that you will install Extjs-3.0.0 completely.
5 | 6 |Webservers

- Web server that can run PHP 5.2 or higher and supports Drupal Clean URLs (Apache with mod_rewrite recommended) 9 |
- Microsoft IIS
Drupal core will work using IIS 5, IIS 6, or IIS 7 if PHP is configured correctly. To achieve clean URLs you may need to use a third party product. For IIS7 you can use the Microsoft URL Rewrite Module or a third party solution.

20 |
- Neologism supports PostgreSQL 7.1 or higher. 21 |
- PHP 5.2.6 for Windows has a bug in its pgsql extension. You will need to replace it with the php_pgsql.dll from version 5.2.5. 22 |

SPARQL fulltext search extensions are provided by a number of vendors (e.g. LARQ and Virtuoso). Giving the absence of standardisation, each vendor uses its own proprietary syntax to express full-text search queries. Currently, we support LARQ, Virtuoso and BigOWLIM.
The example below shows a sample SPARQL query
LARQ query with labeling property is: rdfs:label
Input: label="Galway"
PREFIX rdfs:<http://www.w3.org/2000/01/rdf-schema#>
PREFIX pf:<http://jena.hpl.hp.com/ARQ/property#>
SELECT ?entity ?label (MAX(?score) AS ?score1)
WHERE{
?entity <http://www.w3.org/2000/01/rdf-schema#label> ?label.
(?label ?score) pf:textMatch 'Galway'.
}GROUP BY ?entity ?label
ORDER BY DESC(?score1) LIMIT 3
Virtuoso query with labeling property is: rdfs:label and skos:prefLabel
Input: label="Galway", type= {"<http://dbpedia.org/ontology/PopulatedPlace>","<http://dbpedia.org/class/yago/Locations>"}
SELECT DISTINCT ?entity ?label ?score1
WHERE{
?entity ?p ?label.
?label <bif:contains> "'Galway'" OPTION(score ?score1).
FILTER (?p=<http://www.w3.org/2000/01/rdf-schema#label> ||
?p=<http://www.w3.org/2004/02/skos/core#prefLabel>).
?entity a ?type.
FILTER (?type IN (<http://dbpedia.org/ontology/PopulatedPlace>,
<http://dbpedia.org/class/yago/Locations>)).
FILTER isIRI(?entity).
} ORDER BY desc(?score1) LIMIT 6
Property autocompletion using LARQ
Input: "nam"
PREFIX pf:
SELECT DISTINCT ?p ?label1 ?score1 ?label2 ?score2
WHERE{
[] ?p ?v.
{
OPTIONAL {
?p ?label1.
(?label1 ?score1) pf:textMatch 'nam*'.
}
OPTIONAL {
?p ?label2.
(?label2 ?score2) pf:textMatch 'nam*'.
}
FILTER (bound(?label1) || bound(?label2))
}
} ORDER BY desc(?score1) LIMIT 10

8 |
Identify related RDF datasets
9 |10 | Using Sindice Search API and Cache API, RDF Extension can suggest RDF datasets that contain related data to a column in a Google Refine project. The suggestion is based on examining the results returned by searching a sample set of the data via Sindice. 11 |12 |
13 | -
14 |
Reconcile datasets
15 |16 | You can define Sindice as a target for reconciliation. Most of the times, you will use a domain-restricted reconciliation service (i.e. restrict Sindice search to a particular domain) but you have the option to search the whole Sindice index. Sindice reconciliation service is defined by default once you install the extension (you can find it in the standard Google Refine list of defined reconciliation services labeled Sindice). Further domain-restricted Sindice reconciliation services can be defined through the RDF menu. 17 |18 |
19 |
2 | In this example, I will reconcile a list of people working at the Digital Enterprise Research Institute DERI with the help of Sindice. The CSV file can be downloaded. 3 |
4 |-
5 |
-
6 | Create a Google Refine project from the CSV file. A snippet is shown in the figure below.
7 |
8 |
10 |
9 |
11 | -
12 | From the "name" column drop down menu, select Discover related RDF datasets as shown in the figure below. This will query Sindice for datasets containing RDF data about the first ten rows.
13 |
14 |
16 |
15 |
17 | -
18 | Querying Sindice might take some time (up to 5 minutes). The result is a list of domains containing related data as shown below. Select www.deri.ie and then hit the Add domain-specific Sindice service button. This will define a reconciliation service that search Sindice for RDF data defined under www.deri.ie.
19 |
20 |
22 |
21 |
23 | -
24 | Choose start reconciling... from the column drop down menu of the "name" column. Select the Sindice (www.deri.ie) added to the list of defined reconciliation services. As shown below, type guessing will suggest a list of types with
foaf:Personat the top. 25 |26 |
28 |
27 |
29 | -
30 | Go ahead with the start reconciling button. After a while, google Refine presents reconciliation results with factes about reconciliation decision and top candidate score (see figure below).
31 |
32 |

36 |
37 | Unfortunately, RDFa data on deri.ie is not perfect (yet!). Thus, many of the URIs are broken. I already pinged our lovely web master and hope by the time you try, it will be fixed and you will get awesome results! 38 |
39 |40 | Alternatively, Sindice domain-specific services can be directly added through the RDF menu as shown below. This will directly add the service to the list of defined reconciliation services without going through the step of discovering related RDF datasets. 41 |
