Iris.ai specializes in researching and developing machine learning technologies in the field of Natural Language Processing, Text Understanding and Knowledge Extraction. The company does its own research and pushes the state-of-the art on document similarity metrics, which is one of the core tech components, together with the analysis of word vector spaces and their applications for similarity and compositionality tasks on several information layers. The approach is mainly unsupervised but we have utilized an evaluated annotation set from our community of AI Trainers for benchmarking and improving our tools. Besides that, Iris.ai utilizes external open source NLP algorithms and fuses them together with the in-house built components into a consolidated platform for serving its clients needs.
