--------------------------------------------
Summary: SentimentClassifier needs the PosTag when classifiering a
word
Key: STANBOL-1151
URL: https://issues.apache.org/jira/browse/STANBOL-1151
Project: Stanbol
Issue Type: Bug
Reporter: Rupert Westenthaler
Assignee: Rupert Westenthaler
The SentimentClassifier interface needs to be changed in a way that the PosTag
for the current word is also parsed to the
public double classifyWord(String word);
method. The reason for that is that the same word might have a different
meaning for different POS tags.
An example is the German word
* gefahren (past for to drive)
* Gefahren (plural for Danger)
While the verb does not have an sentiment assigned the Noun has the following
entry
Gefahr|NN -1.0 Gefahren
because of that the SentimentClassifier currently incorrectly assigns a
sentiment value of '-1' even if the word is used as verb in the text.
This will also require to adapt the implementation to support using the POS tag
when looking up the words in the vocabulary
