  With ever-increasing complexity and dynamicity of communication networks,
intelligent network operation and maintenance has become more important to
network operators. With the fast development of artificial intelligence,
concepts such as "Zero Touch", "Intent-based", "Knowledge-defined" and
"Self-driving" networks have become well-known in networking community for a
great vision of making networks automatically manageable and responsive to user
demands. This article discusses how to achieve Zero Touch Networks from the
perspective of language-like systems. We propose a novel hierarchical
`language' framework dedicated for networks to enable the Zero Touch Network,
which covers from symbolizing network components, a unified framework for
understanding network systems, to the logical description with network
semantics. A case study based on the proposed language framework is provided.
Finally, we discuss the challenges and open issues of intelligence models for
zero touch networks.
