post-processing-library-llm 0.0.5

A brief description of package

Installation

You can install Post-processing-library-llm library using pip:

pip install Post-processing-library-llm

Named Entity Recognition (NER)

In this example, we’ll use the Post-processing-library-llm to perform NER on a set of documents and evaluate the results.

from post_processing_library_llm.ner import ner

# Define ground truth and prediction dictionaries
truth_dict = {
    'airplane': ["Boeing B-52 Stratofortress", "predator drone"]
}
prediction_dict = {
    'airplane': ["drone", "sparrow"]
}

# Perform NER and get results
ner_results = ner.named_entity_recognition(truth_dict, prediction_dict, fuzzy_threshold)

# Print the results
print(ner_results)

NER Output:

{‘Correct Entities’: 1, ‘Missed Entities’: 1, ‘False Positive Entities’: 1}

Text Matching Example

Here’s an example of how to perform Text Matching using the Post-processing-library-llm library:

Text Matching involves comparing two text strings and determining how similar or different they are. The post_processing_library_llm provides various text matching algorithms, including direct matching, token overlap, and cosine similarity, and gives all the metrics as output.

In this example, we’ll use the Text Matcher to compare a list of ground truth texts with predicted texts and calculate matching metrics.

from post_processing_library_llm.get_metrics import TextMatcher

# Define ground truth and prediction lists
truth_list = ["this is a ball", "cat", "Toyota Camry"]
pred_list = ["this is a ball", "Ford Mustang", "Toyota Corolla"]

# Perform text matching with cosine similarity
metrics = text_matcher.match_texts(truth_list, pred_list, match_type='cosine_similarity')

# Print the metrics
print(metrics)

Text Matching Output:

{‘Precision’: 1.0, ‘Recall’: 0.3333333333333333, ‘Specificity’: nan, ‘F1 Score’: 0.5, ‘Negative Predictive Value (NPV)’: 0.0, ‘False Positive Rate (FPR)’: nan, ‘False Negative Rate (FNR)’: 0.6666666666666666, ‘False Discovery Rate (FDR)’: 0.0, ‘Accuracy’: 0.3333333333333333, ‘True Positive Rate (TPR)’: 0.3333333333333333, ‘Positive Predictive Value (PPV)’: 1.0, ‘True Negative Rate (TNR)’: nan, ‘Macro Average Precision’: 0.5, ‘Macro Average Recall’: 0.16666666666666666, ‘Macro Average F1 Score’: 0.25, ‘Weighted Average Precision’: 1.0, ‘Weighted Average Recall’: 0.3333333333333333, ‘Weighted Average F1 Score’: 0.5}
