Our goal is to enable AI-application developers and researchers with:
- set of pre-trained NLP models, pre-defined dialog system components (ML/DL/Rule-based) and pipeline templates;
- a framework for implementing and testing their own dialog models;
- tools for application integration with adjacent infrastructure (messengers, helpdesk software etc.);
- benchmarking environment for conversational models and uniform access to relevant datasets.
Agentis a conversational agent communicating with users in natural language (text).
Skillfulfills user’s goal in some domain. Typically, this is accomplished by presenting information or completing transaction (e.g. answer question by FAQ, booking tickets etc.). However, for some tasks a success of interaction is defined as continuous engagement (e.g. chit-chat).

Chainerbuilds an agent/component pipeline from heterogeneous components (Rule-based/ML/DL). It allows to train and infer models in a pipeline as a whole.
The smallest building block of the library is
Component stands for any kind of function in an NLP pipeline. It can
be implemented as a neural network, a non-neural ML model or a
rule-based system. Besides that,
Component can have nested
