SEOUL -- To help office workers quickly analyze and selectively collect information from word-processing documents using artificial intelligence, researchers have developed application programming interfaces that are capable of answering questions based on information included in digital documents and compare sentences to see if they both have the same meaning.

There are AI-based document-comparing solutions that analyze the text in multiple documents and compare to see if they have similar content or sentences. Such solutions are used mainly in the academic field to check the authenticity of papers and journals. The Electronics and Telecommunications Research Institute (ETRI) has developed two AI-based application programming interfaces (APIs) and released the software through its open API portal so that anyone can easily use them.

The Q&A API uses a deep learning model to understand paragraphs and tables. It can answer questions such as "How much travel expenses should I apply for if I am expecting to spend $200 on my business trip?" The API will look for company policies on business travel expenses and answer the question. Another API is capable of recognizing paraphrased texts. AI will read documents and see if sentences from separate documents have the same meaning.

ETRI said the API can be used for the development of other AIs designed to understand the Korean natural language. "We hope that this technology helps South Korean citizens gain quick and convenient access to information and vitalize the domestic AI service market dominated by foreign AI solutions," ETRI language intelligence lab researcher Lim Jun-ho said in a statement on September 7.

The APIs can only analyze and understand word-processing documents compatible with Hangul, an office program produced by South Korea's technology company to Hancom. ETRI said that it will upgrade the software's compatibility so that AI can also understand documents using Microsoft's word-processing software.
