#nerpp --- Named Entity Recognition Using CRF++ and C++

Named Entity Recognition Using CRF++ and C++

To run this code, you should have

• CRF++ (latest version can be found in CRF++ github)

##Compile & Run

• Download CRF++

• Put CRF++-0.58folder into ```nerpp`` folder

• Install CRF++ by running:

cd CRF++-0.58
./configure 
make
sudo make install

• Compile by running:

cmake .
make

• Run:

./nerpp x

• where x is run mode:

  • 1: Train model (read file)
  • 2: Batch test (read file)
  • 3: Single sentence test (stdin)
  • 4: Split data file into 2 files, for training and testing

• Example: With the given data in ./dataset/, first split data into 2 parts by:

./nerpp 4
dataset/data 0.8

Then train a model using the 80% of data:

./nerpp 1
dataset/data_TR

Test model using the 20% of data (result will be automatically saved in data_TS_info.txt:

./nerpp 2
dataset/data_TS

Test single sentence from stdin:

./nerpp 3
