Researcher / AI Company

求人概要 / Role and Responsibility
At LINE, we are actively developing and operating an AI business to become Asia's number one tech company. Positioning AI as a strategic business, we use natural language processing, text, image, face, and voice recognition, voice synthesis, and other proprietary technologies to build a wide selection of AI solutions and products including chatbots, OCR, LINE AiCall, and LINE eKYC for businesses and local governments.
The future is AI. LINE is striving to build a "new normal" wherein AI technologies make up a natural part of life, providing convenience and resolving pain points for businesses and people. LINE envisions a future in which hospitable and helpful AI technologies work for the people.

LINE's AI research and development is reaching a turning point, and we are looking for skilled engineers to boost our research performance.
After launching the LINE CLOVA AI platform and related smart speakers in 2017, and the LINE CLOVA AI solution business in 2019, we are eager to build new AI solutions and are looking for forward-thinking researchers capable of innovative ideation and research on machine learning.
The AI Researcher will be placed in LINE's R&D department and research to build innovative features for LINE's AI platform. We are especially looking for candidates with experience in fields such as image processing, natural language processing, speech processing, machine learning, and AI ethics.

Image processing
The CV-related technologies we currently offer include face recognition, video action recognition, and optical character recognition (OCR). In the future, we will strengthen our research and development on multi, cross-modal, and multi-camera network-based recognition and understanding, virtual character and human animation, and automatic generation and evaluation of ads. In particular, we will promote R&D that is unique to LINE, such as connecting image and video data with our world-leading large-scale language models for speech processing and language understanding.

Natural language processing
In addition to basic analysis techniques such as morphological and syntactic analysis, we develop algorithms for BERT and other pre-trained language models. We are also building a large-scale generic language model called HyperCLOVA, and focused on researching effective prompting to direct tasks to it. Furthermore, we promote R&D on applied natural language processing techniques such as information retrieval, sentiment analysis, document summarization, and document generation.

Speech processing
Voice recognition and voice synthesis are some of LINE's proprietary AI technologies used in many products. In addition to these technologies, we are working to build new applications using voice. Over the years, LINE has released a variety of AI-based products and solutions, including the LINE CLOVA AI platform and a range of smart speakers in 2017, and LINE AiCall in 2019. Part of the LINE CLOVA AI solution business line-up, LINE AiCall is an AI-based phone service with natural conversation capabilities. The AI Researcher can take part in such exciting projects and build commercial products that use end-to-end speech recognition and other cutting-edge speech recognition technologies as well as expressive speech synthesis technology.

AI Ethics
At LINE, we believe that AI should be explainable, safe, robust, resilient, fair, ethical, and protect privacy in order to be trustworthy, and we strive to research and develop such AI technologies to ensure that our users will be able to enjoy our AI-based products and services with confidence. Other areas of research include "AI filters" that suppress harmful language in large-scale language models, proactive risk assessment of AI that uses adversarial machine learning, and explainable and traceable AI for business domains that must be highly reliable such as healthcare.
