#                                                                      #

#
# To build just the reranking parser run-time, execute:
#
# make                 # builds reranking parser programs
#
# To retrain the reranking parser, run the following steps:
#
# make reranker        # builds reranking parser and training programs
# make nbesttrain      # builds 20 folds of n-best training parses
# make eval-reranker   # extracts features, estimates weights, and evaluates
#
# The following high-level goals may also be useful:
#
# make nbestrain-clean # removes temporary files used in nbesttrain
# make nbest-oracle    # oracle evaluation of n-best results 
# make features        # extracts features from 20-fold parses
# make train-reranker  # trains reranker model
# make train-clean     # removes all temporary files used in training
# make sparseval       # download and install SParseval
# make world           # build everything currently supported
#
# I typically run nbesttrain to produce the n-best parses 

# To run 2 jobs in parallel (e.g. on a multiprocessor) run, e.g.,
#
# make -j 2 nbesttrain
#
# This really only helps with nbesttrain, since the other time consuming
# step (reranker feature weight estimation) isn't yet parallelized.

# The environment variable GCCFLAGS can be used to specify
# machine-dependent optimization flags, e.g.
#
# setenv GCCFLAGS "-march=pentium4"
#
# or
#
# setenv GCCFLAGS "-march=opteron -m64"
#
# The top-level make goal builds the reranking parser using a pre-trained
# model.  To build this parser, just run
#
# make 
#
# You may need to tweak the following variables to suit your environment

# GCCFLAGS is not set here, so we use the shell environment
# variable's value.  But you can set it here if you want.
# Version 4.1 and later gcc permit -march=native, but older
# versions will need -march=pentium4 or -march=opteron
#
# GCCFLAGS = -march=native -mfpmath=sse -msse2 -mmmx -m32

# Sample values for clang on Mac OS X
#
# GCCFLAGS="-Wno-deprecated-declarations"
# FOPENMP="-liomp5"
#
# NOTE: libiomp needs to be installed, install using homebrew: brew install libiomp

# CFLAGS is used for all C and C++ compilation
#
CFLAGS ?= -MMD -O3 -Wall -ffast-math -finline-functions -fomit-frame-pointer -fstrict-aliasing $(FOPENMP) $(GCCFLAGS)

# Building the 20-fold training data with nbesttrain 
# --------------------------------------------------

# For training the parser and reranker you will need your own copy of the
# Penn WSJ Treebank.
#
# PENNWSJTREEBANK must be set to the base directory of the Penn WSJ Treebank
#
PENNWSJTREEBANK=/usr/local/data/Penn3/parsed/mrg/wsj/

# NPARSES is the number of alternative parses to consider for each sentence
#
NPARSES=50

# NFOLDS is the number of folds to use, and FOLDS is a list of the numbers
# from 00 to NFOLDS-1 (I couldn't see how to program this in make).
#
NFOLDS=20
FOLDS=00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19

# SECTIONS is a list of sections from the treebank to n-best parse
# using Eugene's standard n-best parser (in addition to the folds).
#
SECTIONS=22 23 24

# NBESTPARSERBASEDIR is the base directory in which the n-best parser is
# located.  If you change this, change NBESTPARSERNICKNAME as well.
#
NBESTPARSERBASEDIR=first-stage

# NBESTPARSER is the n-best parser.  If you change this, please
# change NBESTPARSERNICKNAME below as well.
#
NBESTPARSER=$(NBESTPARSERBASEDIR)/PARSE/parseIt

# NBESTTRAINER is the program (probably a shell script) for training
# the n-best parser.  If you change this, please change
# NBESTPARSERNICKNAME below as well.
#
NBESTTRAINER=$(NBESTPARSERBASEDIR)/TRAIN/trainParser

# NBESTPARSERNICKNAME is a nickname for the n-best parser.  If you 
# experiment with several n-best parsers, give each one a different
# nickname.
#
NBESTPARSERNICKNAME=ec

# TMP specifies a temporary directory used while constructing the
# folds while producing the training parses for the reranker.  You can
# delete this directory after nbesttrain has finished.  On an NFS
# system you may want to change this to a local directory.
#
TMP=tmp

# Extracting features from 20-fold n-best parses
# ----------------------------------------------

# VERSION should be either "final" or "nonfinal".  If VERSION is
# "nonfinal" then we train on folds 00-19, folds 20-21 are used as
# dev, and sections 22 and 24 are used as test1 and test2
# respectively.  If VERSION is "final" then we train on folds 00-21,
# section 24 is used as dev and sections 22 and 23 are used as test1
# and test2 respectively.
#
# VERSION=nonfinal
VERSION=final

# FEATUREEXTRACTOR is the program that used to extract features from
# the 20-fold n-best parses.  If you change this, please pick a new 
# FEATURESNICKNAME below.
#
FEATUREEXTRACTOR=second-stage/programs/features/extract-spfeatures

# FEATUREEXTRACTORFLAGS are flags you want to give to the feature extractor
#
FEATUREEXTRACTORFLAGS=-l -c -i -s 5

# FEATURESNICKNAME is an arbitrary string used to identify a
# particular set of extracted features for training the reranker.  You
# can keep several different sets of feature counts and corresponding
# models around by giving each a unique FEATURESNICKNAME.  If you
# develop a new set of features, give them a new FEATURESNICKNAME so
# they doesn't over-write the existing features.
#
FEATURESNICKNAME=sp

# Estimating weights for features
# -------------------------------

# ESTIMATOR is the program used to estimate feature weights from the
# feature counts. This is the feature weight estimator that gives best
# performance.  There are others in the same directory (e.g., weighted
# perceptron).  If you decide to use a different feature weight
# estimator you should also change ESTIMATORNICKNAME below.  Other sets
# of these variable values can be found in the train-eval-reranker.sh
# script.
#
