Stop Word Filter

This Node Is Deprecated — This version of the node has been replaced with a new and improved version. The old version is kept for backwards-compatibility, but for all new workflows we suggest to use the version linked below.

Filters all terms of the input documents, which are contained in the specified stop word list. The node provides built-in stop word lists for various languages. Alternatively stop word can be loaded from a file. The path to that file can be specified in the node dialog. The stop words need to be written among each other, line by line in a way that each line contains only one stop word.

Case sensitive: If checked the stop words are matched case sensitive otherwise not.
Use built-in list: Specifies if built-in stop word list is used or not. If checked the specified path will be ignored.
Stopword lists: Available built-in stop word lists. If "Use built-in list" is checked, the built-in stop word list to use can be specified here.
Selected file: The location of the stop word file. Stop words need to be written below each other in one column, in a way that each line contains only one stop word.
