#####Description
jeopardy is a RESTful classification utility for automatic validation of free text answers in learning systems. It is build on the WEKA NaiveBayes algorithm implementation. The application also uses the Tartarus Snowball stemming algorithm for feature set reduction.
#####Prerequisites
#####Building and starting the application via Terminal
To build and run the application you need to excecute the following commands within the root directory of the project...
- Build the service:
mvn clean install -Dmaven.test.skip=true - Run the service:
java src/main/java/de/uni_koeln/info/Application
#####REST-Interface
The MVC controller containing the two methods bellow is defined in de.uni_koeln.info.controller.RESTfulController
GET http://localhost:8080/validate?questionId=<QUESTION_ID>&text=<ANSWER>
POST http://localhost:8080/train
The training routin of the POST method is build on the following scheme. Here a short excerpt:
"question": {
"id": 1455,
"text": "Erläutern Sie, wie es zur Einstellung des chemischen Gleichgewichtes kommt.",
...
},
"card_data": {
...,
"answer": { // THIS IS THE TOP ANSWER
...,
"text": "Gemäß dem Massenwirkungsgesetz und in Abhängigkeit von der Temperatur ...",
...
},
"scored_answers": [ // ARRAY OF SCORED ANSWERS, SCORED FROM 1 -3
{
...,
"text": "Im chemischen Gleichgewicht ist die Geschwindigkeit von Hin- und Rückreaktion ...",
"score": 3
},
{
...
}
]
