Sometimes, it is practically or legally not possible to move corpus data to a local machine. This vignette explains the usage of CWB corpora that are hosted on an OpenCPU server.
The GermaParl corpus is hosted on an OpenCPU server with the IP
18.104.22.168 (subject to change). To use the corpus, use the
corpus()-method. The only difference is that you will need
to supply the IP address using the argument
<- corpus("GERMAPARL", server = "http://opencpu.politik.uni-due.de")gparl
gparl object is an object of class
The polmineR at this stage exposes a limited set of its functionality for remote corpora. Simple investigations in the remote corpus are possible.
<- subset(gparl, year == "2006")gparl2006
The returned object has the class
count(gparl, query = "Integration")
count()-method works for
remote_subcorpus objects, too.
count(gparl2006, query = "Integration")
kwic(gparl, query = "Islam", left = 15, right = 15, meta = c("speaker", "party", "date"))
Works for the
kwic(gparl2006, query = "Islam", left = 15, right = 15, meta = c("speaker", "party", "date"))
Create directory for registry file-style files with credentials
Create file with credentials for your corpus in this directory
Note: Filename is corpus id in lowercase
## ## registry entry for corpus GERMAPARLSAMPLE ## # long descriptive name for the corpus "GermaParlSample" NAME # corpus ID (must be lowercase in registry!) ID germaparlsample# path to binary data files ://localhost:8005 HOME http# optional info file (displayed by ",info;" command in CQP) ://zenodo.org/record/3823245#.XsrU-8ZCT_Q INFO https # corpus properties provide additional information about the corpus: ##:: user = "YOUR_USER_NAME" ##:: password = "YOUR_PASSWORD"
Set environment variable “OPENCPU_REGISTRY” in .Renviron to dir just mentioned
Get server whereabouts
<- corpus("MIGPRESS_FAZ", server = "YOURSERVER", restricted = TRUE)x
Upcoming versions of polmineR will expose further functionality. This is a simple proof-of-concept!
