What is Text Summarization?

Text summarization is the process of condensing a text into a comprehensive synopsis. There are two main ways to summarize a text using machine learning. Extractive text summarization pulls keyphrases from a document and uses them to create a synopsis. Abstractive text summarization aims to understand the meaning behind a text and communicate it in newly generated sentences.

To accurately perform text summarization, machine learning algorithms need an understanding of both language and the central message behind each text. In order to develop these abilities, it’s vital that these algorithms are trained on cleaned, tokenized, and accurately summarized datasets.

Lionbridge has the platform, contributors, and project management team necessary to build these datasets in a huge range of global languages. Whether you’re looking to summarize financial reports or build a news aggregator, we can design a custom workflow to help you achieve your goals.
