1. About The Project

Back to ToC

KeyCARE provides a common interface for extracting, categorizing and associating terms extracted from a text:

• Keywords extraction: KeyCARE implements several unsupervised term extraction techniques such as YAKE, RAKE, TextRank or KeyBERT to automatically extract key terms from a text.
• Term categorization: KeyCARE allows the application of term clustering techniques to group similar terms, as well as the training and application of supervised techniques to classify keywords into predefined categories, including SetFit.
• Semantic relation classification: Beyond the identification and categorization of terms, the library supports the use of neural classification models, such as the Transformer's AutoModelForSequenceClassification, to extract the semantic relation between two terms by means of EXACT, BROAD, NARROW and NO_RELATION relationships, which allows interconnecting the extracted terms and can be used for terminological enrichment, among other tasks.

2.1. Installation

Installation can be done using pypi:

   pip install keycare

You might also need to install spacy's es_core_news_sm:

   python3 -m spacy download es_core_news_sm

2.2. Usage

The library is built on 3 main processes: keyword extraction, term categorization and relations extraction. The two first processes have been implemented within a same pipeline in the class TermExtractor, which automatically extracts classified keywords frim pieces of text. The relations extraction process among term pairs or groups of terms is implemented in the other main class, RelExtractor.

TermExtractor

For the use of TermExtractor with default parameters, use the following code:

   from keycare.TermExtractor import TermExtractor
   extractor = TermExtractor()
   extractor("...") # Introduce your text here
   extractor.keywords

This code calls TermExtractor with default parameters on a piece of text and returns the extracted keywords with their assigned class.

RelExtractor

For the use of RelExtractor with default parameters, use the following code:

   from keycare.RelExtractor import RelExtractor
   relextractor = RelExtractor()
   relextractor("...", "...") # Introduce your term pairs here
   relextractor.relations

This code calls RelExtractor with default parameters on pairs of terms and returns the existing relation among them.

For further information on the functioning of the library and the available parameters refer to the tutorials in the nbs folder.
