Products & Technology

The company’s most visible NLP product to date is Embla, a voice-based assistant app for smartphones that answers a wide range of questions in natural language. Embla has been nominated for awards such as UT-sprotinn 2019 at UTmessan and a place on The P&P Startup List 2020. Embla is built on Greynir, Miðeind’s core technology stack. Greynir includes a tokenizer and a fast deep constituency parser, guided by a wide-coverage context-free grammar for Icelandic.

Miðeind has developed Yfirlestur, a spelling and grammar checker for Icelandic text that uses the deep parser, among other methods, to provide much more detailed linguistic advice than has been possible to date.

Miðeind has also developed Vélþýðing, machine translation to and from Icelandic based on state-of-the-art deep neural network technology.

In addition to this, Miðeind has developed a very popular web-based version of a popular crossword game for Icelandic with its good share of hardcore followers.

In order to accomplish all this, Miðeind uses the most powerful supercomputer used for language technology in Iceland. It is built on HPE servers and powered by the latest generation of nVidia Graphic Processor Units, nVidia A100.
