To install elephant simply type
$ make ; make install
this will compile the external tools wapiti and elman and copy the
executables files in /usr/local/bin . To change the destination directory
the variable PREFIX in the Makefile has to be edited.
After installation, elephant is invoked like in these examples:
(PTB-style output)
$ echo 'Good morning Mr. President.' | elephant -m models/english
(IOB output format)
$ echo 'Good morning Mr. President.' | elephant -m models/english -f iob
It is also possible to run elephant from the source directory without need
to install it, by just typing
$ make
and invoking the executable from the current directory, e.g.
$ echo 'Good morning Mr. President.' | ./elephant -m models/english/
Included in the distribution there are the models for sentence and word boundary
detection of English, Dutch and Italian.
