To build a key words database, you will need a set of key word lists. For a decent sized database, it is preferable to build it like this:
1. Make a batch of word lists.
2. Use this to make a batch of keyword lists. Set "faster minimal processing" on as in this shot, so as to not waste time computing plots etc.
3. Now, in KeyWords, choose New | KW Database.
This enables you to choose the whole set of key word files.
Note that making a database means that only positive key words will be retained.
In the Controller KeyWords settings you can make other choices:
minimum frequency for database
If you set this to 5 you will only use for the database any KWs which appear in 5 or more texts
min. KWs per text
If this is set to 10, any KW results files which ended up with very few positive KWs will be ignored.
