+The gazetteer list collector, found in the Tools plugin, collects occurrences
of
+entities directly from a set of annotated training documents and populates
+gazetteer lists with the entities. The entity types and structure of the
+gazetteer lists are defined as necessary by the user. Once the lists have been
+collected, a semantic grammar can be used to find the same entities in new
+texts.

+The target gazetteer must contain a list corresponding exactly to each
+annotation type to be collection (for example, \texttt{Person.lst} for the
+\texttt{Person} annotations, \texttt{Organization.lst} for the
+\texttt{Organization} annotations, etc.). You can use the gazetteer editor to
+create new empty lists for types that are not already in your gazetteer. Note
+that if you do this, you will need to ``Save and Reinitialise'' the gazetteer
+later (the collector updates the \texttt{*.lst} files on disk, but not the
+\texttt{lists.def} file).
-An empty list must be created first for each annotation type, if no list exists
-already. The set of lists must be loaded into GATE before the PR can be run.
-If a list already exists, the list will simply be augmented with any
-new entries. The list collector will only collect one occurrence of each
entry: it
-first checks that the entry is not present already before adding a new one.
+If a list in the gazetteer already contains entries, the collector will add new
+entries, but it will only collect one occurrence of each new entry; it checks
