 ### 3.Calculate similarity matrix (inference)
 ```
 Example: 
-python cal_column_similarity.py -p Test\ Data/self -m model/2022-04-11-17-10-11 -s one-to-one
-python cal_column_similarity.py -p Test\ Data/authors -m model/2022-04-11-17-10-11 -t 0.9
+python cal_column_similarity.py -p Test\ Data/self -m /model/2022-04-12-12-06-32 -s one-to-one
+python cal_column_similarity.py -p Test\ Data/authors -m /model/2022-04-12-12-06-32-11 -t 0.9
 ```
 Parameters:
 - -p: Path to test data folder, must contain **"Table1.csv" and "Table2.csv" or "Table1.json" and "Table2.json"**.
@@ -50,42 +50,43 @@ Parameters:
 - -s: Strategy, there are two options: "one-to-one" and "one-to-many". "one-to-one" means that one column can only be matched to one column. "one-to-many" means that there is no restrictions. Default is "one-to-many".

-- tsm_cosine: cosine similarity computed by sentence-transformers using "paraphrase-multilingual-mpnet-base-v2". Support multi-language column names matching.
+- tsm_cosine: Cosine similarity of column names computed by sentence-transformers using "paraphrase-multilingual-mpnet-base-v2". Support multi-language column names matching.
+- instance_similarity:cosine: Select 20 instances each string column and compute its mean embedding using sentence-transformers. Cosine similarity is computed by each pairs.
