Stop word analysis is performed by VoC Mine in two main ways:
- Automated language-specific removal of common stop words which removes frequently used words such a, an and the from the query. This process is automated and the list of these predefined stop words cannot be changed by end users.
- Custom stop word dictionary created by users. This article describes this second way of stop word editing further.
In certain cases you might want to exclude certain words from lemmata list on an ongoing basis. For example, you have 10 queries with certain shared lemmata which you want to exclude. In this case you can use stop word dictionary to add such lemmata just once and then use the dictionary to exclude it.
It is expected that you use lemmata and not individual text cases in stop word dictionaries. Each dictionary consists of simply a list of lemmata you want to be excluded from some query later. You can name the dictionaries to group certain stop words by their meaning and reuse the dictionaries across multiple queries.
Just like with synonym dictionaries, stop word dictionaries only affect the cloud, table and chart lemmata views within the query editor. They don't affect exports or lemmata in text cases themselves.
Please see "Scope of applicability" section to see how this functionality is integrated into the product.

Scope of applicability
When applied, the aforementioned dictionary will make all lemmata contained within the dictionary to be excluded from all lemmata views: cloud, table and chart.
Please note that stop word dictionaries don't affect actual lemmata count and lemmata list (if included) in the export files. Stop word dictionaries don't affect the lemmata displayed in the text case details.
