similar-sentences 3.0

Similar sentence prediction

Similar sentence Prediction with more accurate results with your dataset on top of BERT pertained model.

Setup

Install the package

pip install similar-sentences

Methods to know

SimilarSentences(FilePath,Type)

• FilePath: Reference to model.zip for prediction. Reference to sentences.txt for training.
• Type: predict or train

.train(PreTrainedModel)

• Used for training the setences. Which required (".txt", "train") as parameter in SimilarSentences
• PreTrainedModel (optional): Any of the below model can be passed for training,by default #1 will be applied

1. bert-base-nli-mean-tokens: BERT-base model with mean-tokens pooling. Performance: STSbenchmark: 77.12
2. bert-base-nli-max-tokens: BERT-base with max-tokens pooling. Performance: STSbenchmark: 77.21
3. bert-base-nli-cls-token: BERT-base with cls token pooling. Performance: STSbenchmark: 76.30
4. bert-large-nli-mean-tokens: BERT-large with mean-tokens pooling. Performance: STSbenchmark: 79.19
5. bert-large-nli-max-tokens: BERT-large with max-tokens pooling. Performance: STSbenchmark: 78.41
6. bert-large-nli-cls-token: BERT-large with CLS token pooling. Performance: STSbenchmark: 78.29
7. roberta-base-nli-mean-tokens: RoBERTa-base with mean-tokens pooling. Performance: STSbenchmark: 77.49
8. roberta-large-nli-mean-tokens: RoBERTa-base with mean-tokens pooling. Performance: STSbenchmark: 78.69

More details

.predict(InputSentences, NumberOfPrediction, DesiredJsonOutput)

• Used for predicting the setences. Which required (".zip", "predict") as parameter in SimilarSentences
• InputSentences: To find the similar sentence for.
• NumberOfPrediction: Number of results for the prediction
• DesiredJsonOutput: The output will be in JSON format. simple produces a plain output. detailed produces detailed output with score

.reload()

• Used for reloading (or) updating the model. Which required (".zip", "predict") as parameter in SimilarSentences

.batch_predict(BatchFile,NumberOfPrediction)

• This method will export the data with 3 columns in excel format. Columns ['Sentence','Suggestion','Score']
• BatchFile: Batch file with sentences to predict, has to be in .txt format.
• NumberOfPrediction: Number of results for the prediction

Getting Started

Train the model with your dataset

Prepare your dataset and save the content to sentences.txt

Glad I could help!

Supply the sentences to build the model.

from SimilarSentences import SimilarSentences
# Make sure the extension is .txt
model = SimilarSentences('sentences.txt',"train")
model.train()

The code snipet will produce model.zip.

Predicting from your model

Load the model.zip from the training.

from SimilarSentences import SimilarSentences
model = SimilarSentences('model.zip',"predict")
text = 'Hi.How are you doing?'
simple = model.predict(text, 2, "simple")
detailed = model.predict(text, 2, "detailed")
print(simple)
print(detailed)

Output looks like,

#simple output
[
  "Hello there! Did I get that right?",
  "Right Hi, how can I help?"
]

#detailed output
[
  [
    {
      "sentence": "Hello there!",
      "score": 0.938870553799856
    },
    {
      "sentence": "Did I get that right?",
      "score": 0.7910412586610753
    }
  ],
  [
    {
      "sentence": "Right",
      "score": 0.9161810654762793
    },
    {
      "sentence": "Hi, how can I help?",
      "score": 0.7824734658953297
    }
  ]
]
