Text Categorization

Configuration Setup

TC Java provides users choices of setting up different options through the configuration file. The default configuration file is ${TC_DIR}/data/config/tc.properties. The variables used in the configuration file are listed in the following table. "Relative path" refers to the path relative to TC top directory, ${ROOT_DIR}.
