My working experiences in the mapping between thesauri

It was an amazing experience to work with large agriculture datasets in order to publish it into the Linked Open Data. It can be used as a background knowledge in the future since there is no universal background knowledge dataset in the world. Recently, I was refreshing my mind with mapping techniques and results after my PhD. I run my matcher between AGROVOC-EUROVOC and got a good number of exact matches (1,200). Again, I run the matcher between AGROVOC-GEMET and found 1,150 exact matches. But, I was extremely happy when I got 13,000 matches between AGROVOC and NAL. The idea is to put everything in one file which can provide services as an online shop for agriculture information in the world and connect all people in one platform of learning and browsing infromation. Today, I am writing just an abstract view of my personal opinion. Soon, I will post matching techniques and difficulties. -:).
