CLAM allows you to quickly and transparently transform your Natural Language Processing application into a RESTful webservice, with which both human end-users as well as automated clients can interact. CLAM takes a description of your system and wraps itself around the system, allowing end-users or automated clients to upload input files to your application, start your application with specific parameters of their choice, and download and view the output of the application once it is completed.
CLAM is set up in a universal fashion, requiring minimal effort on the part of the service developer. Your actual NLP application is treated as a black box, of which only the parameters, input formats and output formats need to be described. Your application itself needs not be network aware in any way, nor aware of CLAM, and the handling and validation of input can be taken care of by CLAM.
CLAM is entirely written in Python, runs on UNIX-derived systems, and is available as open source under the GNU Public License (v3). It is set up in a modular fashion, and offers an API, and as such is easily extendable. CLAM communicates in a transparent XML format, and using XSL transformation offers a modern client-side generated web-interface for human end users.

Installation from the Python Package Index using the package manager pip it the recommended way to
intall CLAM. This is the easiest method
of installing CLAM, as it will automatically fetch and install any
dependencies. We recommend to use a virtual environment (virtualenv) if you
want to install CLAM locally as a user, if you want to install globally,
prepend the following commands with sudo:
CLAM can be installed from the Python Package Index using pip. Pip is usually
part of the python3-pip package (Debian/Ubuntu) or similar, note that
Python 2.7 is not supported anymore (you might need to call pip3 instead of pip on older system). It downloads CLAM and all dependencies
automatically::
$ pip install clam
If you already downloaded CLAM manually (from github), you can do:
$ pip install .
- If pip is not yet installed on your system, install it using:
on debian-based linux systems (including Ubuntu):
$ apt-get install python3-pip
on RPM-based linux systems:
$ yum install python3-pip
Note that sudo/root access is needed to install globally. Ask your system administrator to install it if you do not own the system. Alternatively, you can install it locally in a Python virtual environment:
$ virtualenv --python=python3 env
Or:
$ python3 -m venv env
Then activate it as follows:
$ . env/bin/activate
(env)$ pip install clam
CLAM also has some optional dependencies. For MySQL support, install
mysqlclient using pip. For FoLiA
support, install FoLiA-Tools using pip.
Note: CLAM is designed for Linux-like systems, although the client and data library work everywhere, hosting webservices via clamservice may not work on Windows.
If you installed CLAM using the above method, then you can launch a clam test webservice using the development server as follows:
$ clamservice -H localhost -p 8080 clam.config.textstats
Navigate your browser to http://localhost:8080 and verify everything works
Note: It is important to regularly keep CLAM up to date as fixes and improvements are implemented on a regular basis. Update CLAM using:
$ pip install -U clam
