Collection of tools for modifying PCFG Rulesets

merge_rules.py

PCFG Merge Rules is an open-source Python program that allows you to merge Probabilistic Context-Free Grammar (PCFG) rule sets based on the pcfg_cracker.

Description

PCFG Merge Rules simplifies the process of merging two PCFG rule sets, allowing you to create a new rule set by combining a generic set of rules with an input set. You can also adjust the weight of the input set when merging to control the influence of each set on the final rule set.

Requirements

🐍 Python 3.x

Usage

Run the script from the command line with the necessary arguments. Here is the basic syntax:

python merge_rules.py --rule [GENERIC_RULE_PATH] --input [INPUT_RULE_PATH] --output [OUTPUT_RULE_PATH] --weight [WEIGHT]

GENERIC_RULE_PATH: Path to the generic rule set.
INPUT_RULE_PATH: Path to the input rule set to be merged.
OUTPUT_RULE_PATH: Path where the merged rule set will be saved.
WEIGHT: Numerical weight (0-1) to balance the importance of the input rule set in the merge.

Optional arguments:

--replace_alphas_only: If set, only alpha structures from the input will be merged.
