We proposed a synonym search method to solveproblem over time with a query by an example in a known domain for information in an unknown domain. It seems a natural relation that “Bushin the2000s” is similar to “Reaganin the1980s” because “Bush” and “Reagan” are the president of theUSAin these decades. The abstraction is “AinB” which is similar to “CinD.” We solve theproblem over time by using transformation matrix word vectors over time in the Skip-gram model. The example of theproblem is as below. For instance, the sentence “Bushin the2000s” is similar to “Xin the1980s” is given. We search for the appropriate entity toXof the sentence. Therefore, we focus on the transitivity between the transformation matrix. Our approach is to convert the vector representation of “A” in the model of the word embedding model of the “B” to the vector representation of “X” in the model of the word embedding model of the “D” by getting the transformation matrix between word embedding models. We discuss the parameters of previous work and improve choosing words to make transformation matrix using co-occurrence cluster. Our aim is to search for synonyms in which there are more than the 1000 years of separation. However, there are a few common stable meaning words between the “2000s” and the “1000s.” Therefore, in the situation, there is difficulty to use co-occurrence cluster because the clusters of common words are more than 100,000. That is why, we use the transitive relation (2000s,X)(1500s,Y) , (1500s,Y)(1000s,Z)(2000s,X)(1000s,Z) (in the abstruction, the transitivity is) to solve theproblem over the 1000 years of separation. We had experiments as the demonstration to solve theproblem and evaluate nDCG and MRR.
