          Cross-Language Question Answering (CLQA) Task
             in the Fifth NTCIR Workshop (2004-2005)

Introduction
The CLIR and QAC tasks have been conducted in a series of NTCIR Workshops
for 3 years.  It is right time to step forward to make an attempt to 
promote technologies of Cross-Language Question Answering (CLQA) based 
on a common test set, in addition to the CLIR and QAC tasks as continuing 
tasks. In the light of this, the NTCIR5 will initiate a pilot task, CLQA. 
>From the linguistic viewpoint, CLQA is a much more complicated challenge. 
As a result, we would like to make it much simpler in the question target. 
Only questions about Named Entities are provided in the NTCIR5 CLQA task.

CLQA Subtasks
C->C, E->C, C->E, E->J, J-> E subtasks will be provided in CLQA (J->J will 
be provided in QAC and K->K and E-K are under consideration). The score of
outputs of CLQA tasks is the fraction of responses judged correct.
