Text API

API Service that Understands and Analyzes the Meaning of Sentences/Texts

Text API is a type of API that helps with the understanding and analysis of sentences and texts based on a pre-trained language model. With Summary API and TS(Semantic Textual Similarity) API being two of the first to be launched, more APIs are to be provided in the future. Summary API make a summary of a document, whereas STS API compares two texts and evaluates how similar they are in terms of meaning.

Overview

  • Korean Pre-Trained Language Model

    Text API service is based on Korean pre-trained language model. The Korean pre-trained language model studied written Korean texts from news articles and Korean Wikipedia to serve various business use cases. In addition, it uses a patented model compression architecture, differentiating itself from other Korean language models in the market. Therefore, it can be used for various business situations such as VOC systems and chatbots.

  • Text Summary

    Text API uses the abstractive summarization approach for text summaries. While the extractive summarization approach summarizes key sentences, abstractive summarization uses Natural Language Generation (NLG) technique to capture the entire context and create a new sentence. With text API, analysts generating business insights through texts can benefit greatly from time and cost savings.

  • Semantic Textual Similarity

    Semantic Textual Similarity(STS) helps evaluate two texts in terms of meaning or context. For this purpose, Siamese Neural Network(SNN) and Convolutional Neural Network(CNN) are used, reducing processing time. Capturing the contextual similarity can later be utilized for search features.
