Dear Dr. Fan, 

Please download the latest Wiki answer module V2.0 from the following link. In this release, I have modified these: 

[ https://www.dropbox.com/s/65ts8paj93no08o/WIKIQA_V2.0.tar.gz?dl=0 | https://www.dropbox.com/s/65ts8paj93no08o/WIKIQA_V2.0.tar.gz?dl=0 ] 

- Add 高度, 墓地 and custom 寿命, 成立或建立年份 attributes in parsing questions 
- Fix a bug of entity linking (regarding conversion between traditional chinese and simplified one) 

This version answers 50% more questions than the previous version and at the same time increase the precision from 90.9 to 94.1%. 

Previous (V1.0.3): 20/22 = 90.9% 
Current (V2.0): 33/35 = 94.1% 

Note that in this version, I have specifically looked at the errors of the overall system and focused on using information from Wikidata to solve them, i.e., 
(Q) 苏轼几岁时过世? (WikiQA) get_year(苏轼的死亡日期 - 苏轼的出生日期) = 62岁 

== gained corrects (15) ==
