3. For ambiguous meaning taxonomy terms, you need to create respective filter condition for each meaning with different weight value. The one has greater weight value will overwrite those have lesser weight value. For instance, taxonomy term of 'CMS' has different meaning in different pages or content types or fields. You can create a filter condition with a less weight applied to all pages across whole site that has a general meaning, for example CMS means 'Content Management System' in most of pages. But in certain pages or content types or even fields, CMS means something else.

You can go to the text format setting UI to check and update them. For example, you can to go '/admin/config/content/formats/manage/basic_html' and add following into the 'Allowed HTML tag' settings.
