Merge base on a inconsistent string variable

I have two datasets. Dataset 1 has many more variables and has an unique ID for each observation (articles I found in a lit review). Dataset 2 does not have an ID variable but it has similar variables than dataset 1 such as Article_Name Year_Publications etc also dataset 2 has a variable that dataset 1 does not have. I would like to merge the two data sets base on the Article_Name variable. This is a string variable and the values can be slight different in the two datasets.
For example:
dataset 1
Article_Name Breast cancer and partity
dataset 2
Article_Name breast Cancer and Parit

Perhaps I can use the Article_Name variable and the year to merge my datasets.

Can any one help me with this, please? I would appreciate.

Please see attched my 2 datasets
