2. Defined _Annotation_ are used to add information to an _Annotated_ instance
(like a Span). For adding annotations the use of _Annotation_s is required to
ensure type safety. The following code snippet shows how to add an PosTag with
the probability 0.95.
- :::java
- PosTag tag = new PosTag("N"); //a simple POS tag
- Token token; //The Token we want to add the tag
- token.addAnnotations(POS_ANNOTATION,Value.value(tag),0.95);
-
+ :::java
+ PosTag tag = new PosTag("N"); //a simple POS tag
+ Token token; //The Token we want to add the tag
+ token.addAnnotations(POS_ANNOTATION,Value.value(tag),0.95);
3. For consuming annotations there are two options. First the possibility to
use the _Annotation_ object and second by directly using the key. While the 2nd
option is not as nicely to use (as it does not provide type safety) it allows
consuming annotations without the need to have the used _Annotation_ in the
classpath. The following examples show both options
- :::java
- Iterator<Token> tokens = sentence.getTokens();
- while(tokens.hasNext){
- Token token = tokens.next();
- //use the POS_ANNOTATION to get the PosTag
- PosTag tag = token.getAnnotation(POS_ANNOTATION);
- if(tag != null){
- log.info("{} has PosTag {}",token,tag.value());
- } else {
- log.infor("{} has no PosTag",token);
- }
- //(2) use the key to retrieve values
- String key = "urn:test-dummy";
- Value<?> value = token.getValue(key);
- //the programmer needs to know the type!
- if(v.probability() > 0.5){
- log.info("{}={}",key,value.value());
+ :::java
+ Iterator<Token> tokens = sentence.getTokens();
+ while(tokens.hasNext){
+ Token token = tokens.next();
+ //use the POS_ANNOTATION to get the PosTag
+ PosTag tag = token.getAnnotation(POS_ANNOTATION);

The _Annotated_ interface supports multi valued annotations. For that it
defines methods for adding/setting and getting multiple values. Values are
sorted first by the probability (unknown probability last) and secondly by the
insert order (first in first out). So calling the single value getAnnotation()
method on a multi valued field will return the first item (highest probability
and first added in case of multiple items with the same/no probabilities)
