PerceptronTagger is not defined

[LarsWl]

I try do some pos tagging, but module PerceptronTagger is not defined. There is error:

julia> tagger = TextAnalysis.PerceptronTagger(true)
ERROR: UndefVarError: PerceptronTagger not defined
Stacktrace:
 [1] getproperty(x::Module, f::Symbol)
   @ Base ./Base.jl:35
 [2] top-level scope
   @ REPL[21]:1

I tried to find definition in code, there is only export in main module and usage in tag_pos! (also raise same error)

There is PerceptronTagger in TextModels.jl
