在我的计划中，我使用json连接到网址以检索Jsoup。
以下是检索json [拥有subject = example]的方法：
private void result() throws IOException {
Properties props = new Properties();
props.setProperty("annotators", "tokenize,ssplit,pos,lemma,depparse,natlog,openie");
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
List<String> list = newsList.getSelectedValuesList();
for (String s : list) {
Annotation doc = new Annotation(s);
pipeline.annotate(doc);
for (CoreMap sentence : doc.get(CoreAnnotations.SentencesAnnotation.class)) {
// Get the OpenIE triples for the sentence
Collection<RelationTriple> triples =
sentence.get(NaturalLogicAnnotations.RelationTriplesAnnotation.class);
// Print the triples
for (RelationTriple triple : triples) {
/* replace space with "_" */
String subject = triple.subjectLemmaGloss().replace(" ", "_");
String object = triple.objectGloss().replace(" ", "_");
String kb = "http://api.conceptnet.io/c/en/" + subject;
Document docKb = Jsoup.connect(kb).get();
String json = docKb.body().text();
Gson gson = new Gson();
Map<String, Object> asMap = gson.fromJson(json.toString(), Map.class);
List<Map<String, Object>> edges = (List) asMap.get("edges");
for (Map<String, Object> edge : edges) {
if (edge.containsKey("surfaceText") && edge.containsKey("weight")) {
txtAreaNews.append(edge.get("surfaceText").toString() + "\n");
txtAreaNews.append("Weight: " + edge.get("weight").toString());
}
txtAreaNews.append("\n");
}
}
}
}
}
这是我从html的网址中检索到的txtAreaNews.append(docKb.text());：

我想问一下，如何从Jsoup或Gson的上述数据中获取"surfaceText"和"weight"？
答案 0 :(得分：2)
您可以使用Gson将JSON反序列化为Map，然后询问Map。
以下是一个例子：
String kb = "http://api.conceptnet.io/c/en/example";
Document docKb = Jsoup.connect(kb).get();
String json = docKb.body().text();
Gson gson = new Gson();
Map<String, Object> asMap = gson.fromJson(json, Map.class);
List<Map<String, Object>> edges = (List) asMap.get("edges");
for (Map<String, Object> edge : edges) {
// check that the response contains a surfaceText
if (edge.containsKey("surfaceText")) {
// check that the surfaceText value is non-null
String surfaceText = (String) edge.get("surfaceText");
if (surfaceText != null) {
System.out.println(edge.get("surfaceText"));
}
}
if (edge.containsKey("weight")) {
System.out.println(edge.get("weight"));
}
}
此代码将打印出来：
[[apology]] is a type of [[example]]
2.0
[[example]] is a type of [[admonition]]
2.0
[[example]] is a type of [[information]]
2.0
[[exception]] is a type of [[example]]
2.0
... etc
