+Loading this plugin adds a ``Populate from Twitter JSON files'' option to the
+GATE Corpus right-click menu. Selecting this option bringgs up a dialog that
+allows you to select one or more files of tweets in the Twitter API's JSON
+format and set the following options to populate the corpus.
+%%
+\begin{description}
+\item[Encoding] The default here is UTF-8 (regardless of your Java default) to
+ conform to Twitter JSON.
+\item[One document per tweet] If this box is ticked, each tweet will produce a
+ separate document. If not (the default), each input file will produce one
+ GATE document.
+\item[Content keys] The values of these JSON keys are converted into strings
and
+ concatenated into each tweet's document content. Colon-delimited strings
+ specify nested keys, e.g., ``\texttt{user:name}'' will yield the value of the
+ \texttt{name} key in the map that is the value of the \texttt{user} key.
+ Missing key sequences are ignored. Each span of text will be covered by an
+ annotation whose type is the key sequence.
+\item[Feature keys] The key sequences and values of these JSON keys (where
+ present) are turned into feature names and values on the tweet's main
+ \texttt{Tweet} annotation.
+\item[Save configuration] This button saves the current options in an XML file
+ for re-use later.
+\item[Load configuration] This button sets the options according to a saved XML
+ configuration.
+\end{description}
+%%
+Every tweet is covered by a \texttt{Tweet} annotation with features specified
by
+the ``feature keys'' option. Multiple tweets in the same GATE document are
+separated by a blank line (two newlines).
+
+Corpus population from Twitter JSON files is also accessible programmatically
+when this plugin is loaded, using the public static void method
+\texttt{gate.corpora.twitter.Population.populateCorpus(final Corpus corpus, URL
+ inputUrl, String encoding, List<String> contentKeys, List<String>
featureKeys,
+ int tweetsPerDoc)}.
