It comes from the header of an ELF shared object...

...and is not necessarily the same as the real name, think of it
as an alias name that is used for recording dependencies and
that is typically only changed if the library's ABI changes in a
backwards-incompatible way. You can extract it e.g. via
"readelf -d libzlui.so | grep SONAME" or
"objdump -p libzlui.so | grep SONAME".
http://en.opensuse.org/openSUSE:Shared_library_packaging_policy
explains in detail how to translate the soname into a package
name.
