Modify the structure of the MRF graph. Only terms belonging to one concept, or terms belonging to two related concepts, are used as a retrieval unit.
The P@10 of independent MRF model is 0.4920 on CLEF2013 dataset; Adding concept, it's 0.4960; Adding two related concepts, it's 0.5060.
Plan for this Week:
Progress is seen in last week's work, but not significant.
Use a more accurate retrieval unit, combine the two related concepts, and their relation keyword, as a whole.
