What is the difference between these crawled title properties?

Question

In SharePoint 2013, what is the difference between these title crawled properties when I am working with Word Documents?

• MetadataExtractorTitle
• Office:2
• ows_BaseName
• Title
• Basic:displaytitle
• Basic:10
• Basic:9

I can't find a single source online that gives a clear definition on how each of these items relate to a Word Document. I do see under Site Settings -> Search Schema in SharePoint 2013, that I can re-order these title items. But I would like to know what I am actually pushing to the top first with a clear understanding on what it does / pull.

Thanks

There is however a hidden mechanism present in SharePoint 2013 which is called title metadata extraction which overwrite the “Title” managed property with a value SharePoint extracts from parts of Word and PowerPoint documents.
