The correct term is compare:

• to examine (two or more objects, ideas, people, etc.) in order to note similarities and differences (Dictionary.com)
• to examine the character or qualities of especially in order to discover resemblances or differences (Merriam-Webster)

Because you are working with data and performing a detailed analysis of one or more aspects of these data sets, you could also use the term analyze.

• to study or determine the nature and relationship of the parts of by analysis (Merriam-Webster)

However, this word lacks the specific meaning that you are looking at two things, not just one.

If you don't need a single word, you could state:

I am going to comprehensively identify the list of differences in context and structure...

That is precise, but at the cost of being quite verbose.
