The dependency tree’s score is higher than that from binary tree, while it slightly decrease after 3-th level. In the first four cases that we could see the results by changing the word vectors and tree structures. We conclude that almost at every case our approach consistently outperformed uSIF and ParaMNT and Dependency Tree is the best combination. In STS-Benchmark test set, ROTS outperformed uSIF about 1.4 in average of those four different cases. Without any of those, the results is much worse than uSIF.
