Installation Procedure

To install CUE Semantic on an Ubuntu system, do the following:

Log in as root.
If necessary, add the CUE apt repository to your list of sources:
```
# echo "deb http://user:password@apt.escenic.com stable main non-free" >> /etc/apt/sources.list.d/escenic.list
```
where user and password are your CUE download credentials (the same ones you use to access the CUE Maven repository). If you do not have any download credentials, please contact CUE support.

Enter the following commands:

# apt-get update
# apt-get install cue-semantic-enrichment-service

If you intend to use the feedback service to return training data to the semantic analysis service, then you also need to enter:
```
# apt-get install cue-semantic-feedback-service
```

On RedHat / CentOS systems, enter the following command as root:

# rpm -Uvh https://user:password:yum.escenic.com/rpm/cue-semantic-enrichment-service-1.9.0-5.x86_64.rpm

to install the main service, and if required:

# rpm -Uvh https://user:password:yum.escenic.com/rpm/cue-semantic-feedback-service-1.9.0-5.x86_64.rpm

to install the feedback service.

Note that:

The feedback service can only be used together with an Atilika back end.
Even if you intend to use an Atilika back end, use of the feedback service is optional.
