Hi!
Using the code below, I can get spotlight results as a list of
DBpediaResource. Using the method getFullUri() from the class DBpedia
Resource, I can get the uri of the results. I'd like to get a description
to each result, is it possible in Spotlight?
*The code is below:*
/**
* Simple web service-based annotation client for DBpedia Spotlight.
*
* @author pablomendes, Joachim Daiber
*/
public class EnglishDBpediaSpotlightClient extends AnnotationClient {
private final static String API_URL = "http://spotlight.dbpedia.org/";;
//in english
private static final double CONFIDENCE = 0.0;
private static final int SUPPORT = 0;
@Override
public List<DBpediaResource> extract(Text text) throws
AnnotationException {
LOG.info("Querying API.");
String spotlightResponse;
try {
GetMethod getMethod = new GetMethod(API_URL + "rest/annotate/?"
+
"confidence=" + CONFIDENCE
+ "&support=" + SUPPORT
+ "&text=" + URLEncoder.encode(text.text(), "utf-8"));
getMethod.addRequestHeader(new Header("Accept",
"application/json"));
spotlightResponse = request(getMethod);
} catch (UnsupportedEncodingException e) {
throw new AnnotationException("Could not encode text.", e);
}
assert spotlightResponse != null;
JSONObject resultJSON = null;
JSONArray entities = null;
try {
resultJSON = new JSONObject(spotlightResponse);
entities = resultJSON.getJSONArray("Resources");
} catch (JSONException e) {
throw new AnnotationException("Received invalid response from
DBpedia Spotlight API.");
}
LinkedList<DBpediaResource> resources = new
LinkedList<DBpediaResource>();
for(int i = 0; i < entities.length(); i++) {
try {
JSONObject entity = entities.getJSONObject(i);
resources.add(
new DBpediaResource(entity.getString("@URI"),
Integer.parseInt(entity.getString("@support"))));
} catch (JSONException e) {
LOG.error("JSON exception "+e);
}
}
return resources;
}
public static void main(String[] args) throws Exception {
EnglishDBpediaSpotlightClient c = new
EnglishDBpediaSpotlightClient();
Text text = new Text("Google Inc. is an American multinational
public corporation " +
"invested in Internet search, cloud computing, and
advertising " +
"technologies. Google hosts and develops a number of
Internet-based " +
"services and products, and generates profit primarily
from advertising " +
"through its AdWords program.");
System.out.println(text.toString());
List<DBpediaResource> response = c.extract(text);
PrintWriter out = new
PrintWriter("AnnotationText-Spotlight.txt.set");
for( DBpediaResource dbResource : response ) {
* System.out.println( dbResource.getFullUri())*;
*//here, I can get the Uri for each result.
*
}
}
}
*Thank you!!!
