Initial Commit

This version is based on the prototype branch of helloqa. For helloqa, we made the following changes:

• Fixed dependency errors
• Fixed SQL errors
• Fixed platform errors

For DSO project, we convert the components developed in summer'10 to CSE's phases. More specifically, we have converted the following components:

• AnswerTypeExtractor (https://github.com/oaqa/helloqa/tree/prototype/src/main/java/edu/cmu/lti/oaqa/openqa/dso/phase/answertype)
• KeytermExtractor (https://github.com/oaqa/helloqa/tree/prototype/src/main/java/edu/cmu/lti/oaqa/openqa/dso/phase/keyterm)
• ICEventExtractor (https://github.com/oaqa/helloqa/tree/prototype/src/main/java/edu/cmu/lti/oaqa/openqa/dso/phase/icevent)
• PassageRetrieval (https://github.com/oaqa/helloqa/tree/prototype/src/main/java/edu/cmu/lti/oaqa/openqa/dso/phase/passage)
• InformationExtractor (https://github.com/oaqa/helloqa/tree/prototype/src/main/java/edu/cmu/lti/oaqa/openqa/dso/phase/ie)
• AnswerGenerator (https://github.com/oaqa/helloqa/tree/prototype/src/main/java/edu/cmu/lti/oaqa/openqa/dso/phase/answer)

Those components are extended from the following abstract classes：

• edu.cmu.lti.oaqa.openqa.dso.framework.base.AbstractAnswerTypeExtractor
• edu.cmu.lti.oaqa.openqa.dso.framework.base.AbstractICEventExtractor
• edu.cmu.lti.oaqa.openqa.dso.framework.base.AbstractKeytermExtractor
• edu.cmu.lti.oaqa.openqa.dso.framework.base.AbstractPassageRetrieval
• edu.cmu.lti.oaqa.openqa.dso.framework.base.AbstractInformationExtractor
• edu.cmu.lti.oaqa.openqa.dso.framework.base.AbstractAnswerGenerator

The JCas objects are handled by the following classes:

• edu.cmu.lti.oaqa.openqa.dso.framework.jcas.AnswerTypeJCasManipulator
• edu.cmu.lti.oaqa.openqa.dso.framework.jcas.ICEventJCasManipulator
• edu.cmu.lti.oaqa.openqa.dso.framework.jcas.KeytermJCasManipulator
• edu.cmu.lti.oaqa.openqa.dso.framework.jcas.DocumentJCasManipulator
• edu.cmu.lti.oaqa.openqa.dso.framework.jcas.AnsJCasManipulator

Converting Requirements system To run the system, we have to make sure that the following files exist under helloqa:

• conf folder with its property files (used by Ephyra)
• res folder with all its files
• install indri by following the instructions http://lemur.sourceforge.net/indri/
• copy the libindri_jni.so file generated to helloqa/lib/
• if the file libindr_jni.so cannot be found, try ./configure --prefix= --enable-java --with-javahome=$JAVA_HOME, and make, make install again
• We also employ the type system developed previously (summer '11) for DSO, the type system can be found here: https://github.com/oaqa/helloqa/blob/prototype/src/main/resources/edu/cmu/lti/oaqa/OAQATypes.xml
