I am trying to parse our training data, and unfortunately every now and then, an error breaks the parsing.

[Thread 1] pl-fli.c:2428: codeToAtom: Assertion failed: chrcode >= 0
Parser process 7070 has crashed on sentence 299. If you don't see swipl error message, try parsing sentence in single-processed mode

First of all, the parser is probably reporting a wrong sentence id, because the output file only has less sentences than 299. Using --process 1 does not prevent the error from occuring.

I am not really interested for the particular sentence causing the error, but I would appreciate it if the parser can go on with the next sentence of the given file, instead of crashing.

Hello, I'm on Yosemite. I installed everything and downloaded the latest model files. When I run ./parzu I get this error:

$ echo "Das ist ein Test." | ./parzu

Error: Cannot open transducer file ../zmorge-20150315-smor_newlemma.ca

But if I use a tagged file, it works fine:

/external/clevertagger/ contains clevertagger (folder), hdt_ab.zmorge-20140521-smor_newlemma.model and zmorge-20150315-smor_newlemma.ca.

in clevertagger/config.py, I have set SMOR_MODEL = '../zmorge-20140521-smor_newlemma.ca'.

in ParZu's config.ini, I have set smor_model = external/zmorge-20150315-smor_newlemma.ca.

Now, if you look at the error message above, you would think that it's the path in the clevertagger config.py causing the problem. But I can run clevertagger successfully on its own. So why can't ParZu seem to load clevertagger? Thanks for your help.

Hi again,

since the pre-installed version of swi-prolog is old, and our administrators are not willing to upgrade it with custom ways, I tried to compile version swi-prolog 7.1.27 myself. Unfortunately, although swi-prolog compiled fine, I cannot find which is the proper way to make parZu run with it.

In particular, I tried two ways:
(a) modify parzu.py lines 25 and 30, in order to point to the exact location of swipl, e.g. /project/folder/software/swipl/swip . After this, parsing only gave me empty output.
(b) modify $PATH variable of the system, so that 'swipl' command looks on the freshly compiled folder instead of /usr/bin/swipl (old version). This gives an error [FATAL ERROR: Could not find system resources] which I am unable to fix, although I set $SWI_HOME_DIR both from commandline and inside the python script

could you please advise on how to proceed?
cheers

I am using parzu to get features for documents that I first process with Spacy. For this reason, I am sending pre-tokenized input to Parzu. I noticed that some documents, even if the document or the longest sentence is not very big, need very long to parse.

Here is an example text, already preprocessed/tokenized, url-encoded and added as a parameter to the complete URL to process it:

http://localhost:5003/parse/?inputformat=tokenized&text=F%C3%BCr%0AEin-%0Aund%0AUmsteiger%0A%3C%0Atable%0Awidth%3D%2275%0A%25%0A%22%0Aborder%3D%220%0A%22%0A%3E%0A%3C%0Atr%0Abgcolor%3D%22%23000000%0A%22%0A%3E%0A%3C%0Atd%3E%3Cfont%0Acolor%3D%22%23FFFFFF%0A%22%0Asize%3D%222%0A%22%0Aface%3D%22Arial%0A%2C%0AHelvetica%0A%2C%0Asans-serif%22%3EEin%0ALeitfaden%0Adurch%0Aden%0ALinux-Dschungel%0A%3C%0A/font%3E%3C/td%0A%3E%0A%3C%0A/tr%0A%3E%0A%3C%0A/table%0A%3E%0ATOP-SITES%0Af%0Af%0Ahttp%3A//www.cs.Helsinki.FI/~torvalds/%0AOffizielle%0AHomepage%0Avon%0ALinus%0ATorvalds%0Ahttp%3A//www.zdnet.de/linux/%0AZDNet-Special%0Ahttp%3A//www.linux.com/%0ALinx.com%0A-%0ADie%0ALinux-Site%0Aim%0ANetz%0Ahttp%3A//www.heise.de/ix/linux/%0ADie%0ALinux-Seiten%0Ader%0AZeitschrift-IX%0Ahttp%3A//www.linux.de/%0ALinks%0A%2C%0ANews%0A%2C%0A....%0Ahttp%3A//www.it-nachrichten.de/news/98742119/html/t/links/index.html%0AUmfangreiche%0ALinkseite%0Ahttp%3A//li.luga.or.at/%0ALinux-International%0Ahttp%3A//www.linux.org/%0ALinux-User-Site%0Ahttp%3A//www.linux.at/%0ALinux%0Ain%0A%C3%96sterreich%0AKURSE%0Af%0Af%0Ahttp%3A//tux.isCool.net%0ALinux%0AAnf%C3%A4nger%0AForum%0Ahttp%3A//www.pro-linux.de/%0ANews%0Aund%0AWorksshops%0Ahttp%3A//linux-forum.notrix.de%0ALinux%0AForum%0Ahttp%3A//public.surfree.com/rimez/master.html%0AThe%0ALinux%0ANewbie%0Ahttp%3A//www.rennkuckuck.de/linux/%0ALinux-Einf%C3%BChrung%0A-%0AUmfangreiche%0AEinf%C3%BChrung%0Aund%0ANachschlagewerk%0Ahttp%3A//user.cs.tu-berlin.de/~milenium/index.html%0AN%C3%BCtzliches%0Af%C3%BCr%0AEinsteiger%0Ahttp%3A//www.guug.de/~winni/linux/%0ACrash-Kurs%0Ahttp%3A//www.zfescht.ch/pages/info/linux/linux.htm%0AWichtige%0ALinux-Befehle%0ASOFTWARE%0Af%0Af%0Ahttp%3A//univie.linuxberg.com/%0ALinuxberg%0A-%0ABei%0AWindows-UserInnen%0Aals%0ATUCOWS%0Abekannt%0Aftp.tuwien.ac.at/linux/%0AFTP-Server%0ATU-Wien%0ABENUTZEROBERFL%C3%84CHEN%0Af%0Af%0Ahttp%3A//www.kde.org%0AK%0ADesktop%0AEnvironment%0Ahttp%3A//www.gnome.org%0AGNOME%0AProject

At this moment, the parzu demo servers is not usable (I am getting a 504 gateway time-out) so I could not test this data there, but one it works again it should be testable using:

Online demo version of ParZu (https://pub.cl.uzh.ch/demo/parzu/) returns a parse of a random sentence instead of the input. Is it a bug or a feature?

The timeout values for reading from the swipl processes is hard-coded to 10 seconds in parzu_class.py. I found a large number of cases where this was not enough.

It would be very helpful if these values could get changed via the options map that gets passed to the Parser.__init__ method.

Hello together,

I tried some sentences with my local Parzu-Version ( TüBa Statistics included ).
The results are different to the Parzu Service on the WebPage.
Do you know the reason for that?

Thanks in advance.

Hello, I am with macOS Sierra and I already followed the instructions by tabidots:
#4

That means:

• I edited the install.sh: "sed -i" to "sed -e"
• after that the install.sh runs but the path to ".../ParZu/external/zmorge-20140521-smor_newlemma.ca" isn't touched in the config.ini and external/clevertagger/config.py, so I changed it manually

But still, I get this error message:

Starting tokenizer

Do you have any idea how I could fix this? What is the input model file?

Thank you!

Hello together,

I have the Tüba-D/Z corpus in the right format ( CONLL, UTF-8 ).
When I run create_statistics.sh on the Tüba File CONLL2006 I get:
"Illegal UTF-8 continuation" error.
If I run CONLL2011 there is another message saying:
''/1: Undefined procedure: w/7
Exception: (11) w(_4114, _4120, _4148, ne, _4152, _4126, _4132) ?

Thanks for your help in advance.

I tried to setup ParZu but I didn't find the required sfst library anywhere (the ftp server seems to be down). Can you provide me a working download link or do you have any solution to work without this library?

Hello,

i am pretty sure, that my config-file is right.

Is there a proper way to process multiple files without reinitialising the parser again and again? I need it to parse over 4k files to annotate a training set but this would take by far to long if I just use the command again and again for each file (~11h). I could just stick them togther and split them afterwards but thats kinda "dirty".

Hi @rsennrich

Using the sentence: "Das ist diese alte Tochter jener Frau und ihres hübschen Mannes" resulting a dependency between "und" (KON) and "ihres" (PPOSAT). Not correct so far I think ?

PPOSAT depends zu NN ("Mannes"), isn´t it?

thnx!
Florian

Hi @rsennrich,

we're playing around with ParZu, which is really fun and awesome work.

But we find a small but important differnce between the output of your docker image and your online tool https://pub.cl.uzh.ch/demo/parzu/.

sentence: Eigentlich ist der von Geburt an perfekte Mann in der Lage, alles zu machen.

1. is the output of your online tool
2. is the docker image output

Could you image how this difference could appear. Doesn't github has the current version?

Thank you for your feedback

Hi, i am really sorry if this issue is trivial, but I cannot seem to make this work.

I extracted the module in my python37/Lib/site-package folder and tried to run the provided lines

import parzu_class as parzu #line1
options = parzu.process_arguments() #line2
ParZu = parzu.Parser(options) #line3
sentences = ParZu.main('Das ist ein Test. Das auch.') #line4
for sentence in sentences: #line5
print sentence #line6

I had to change line 1 in "import parzu" because otherwise it would not find the module and line 6 which is missing the () for the print function.

I however still get the following error:

"module 'parzu' has no attribute 'process_arguments'"

Do you have any sugestion?

I am using python on Windows 10, x64

Hi 👋,

this is a feature request for an additional input format that also tackles the output format. I often have additional annotations like a document id or a sentence id for given sentences and I want to preserve the annotations in the parses.

An input could look like this:

documentId sentenceId sentence
0 0 first sentence, first document
0 1 second sentence, first document
1 0 first sentence, second document

For the output, I propose an one sentence per line format since this is easy to post process.

0 1 Der Arzt arbeitet im Krankenhaus . Der@@Art@@der@@def|Masc|Nom|Sg Arzt@@nn@@arzt@@masc|Nom|Sg arbeitet@@VVFIN@@arbeiten@@3|Sg|Pres|Ind im@@APPRART@@in@@dat Krankenhaus@@nn@@Krankenhaus@@neut|Dat|Sg .@@$.@@--@@_ DET(arzt-1,der-0) SUBJ(arbeiten-2,arzt-1) S(arbeiten-2,arbeiten-2) PP(arbeiten-2,in-3) PN(in-3,krankenhaus-4) ROOT(-5,-5)

I already tried to re-add the annotations after the parsing myself. However, this solution doesn't work since ParZu computes in a multi-threaded manner and doesn't preserve the input order in its output.

To overcome this issue, one could introduce some sort of buffer that stores finished sentences after parsing. In order to preserve the input order the buffer could flush sentences in the correct order once a sequence is computed. Do you see the problem when the output parses don't match the input?

Hello,
the parser works great and I would like to reproduce the dependency graph
that I saw in your example.

I am using the docker image and tried the option "conll" and "graphical" as an output.
"graphical" seems to include the svg file but I would like to understand how to find the hierarchical arrows between the different words based on the "conll" data (not just the final image, but in some kind of hierarchical structure.)

Running parzu_server.py with python3.1 I get the following error.

2022-04-20T08:32:54.677401533Z   File "parzu_server.py", line 64, in __init__

I believe this to be related to https://stackoverflow.com/questions/52663518/python-subprocess-popen-doesnt-take-text-argument

To run the code, I used the following Dockerfile

RUN apt-get update && apt-get -y install software-properties-common && add-apt-repository ppa:deadsnakes/ppa
RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get -y install \
    git \
    swi-prolog \
    sfst \
    unzip \
    wget \
    python3.1 \
    python3-pexpect \
    python3-flask

ADD https://api.github.com/repos/rsennrich/ParZu/git/refs/heads/master version.json
RUN git clone https://github.com/rsennrich/ParZu

RUN (cd ParZu; bash install.sh)

RUN apt-get update && apt-get -y install curl

EXPOSE 5003

WORKDIR /ParZu
CMD python3 parzu_server.py --host 0.0.0.0

To circumvent this error, I also tried using python3.7. However, this causes the server to respond with an empty list on the first request, with subsequent requests working fine.

This can be reproduced with the following Dockerfile

RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get -y install \
    git \
    swi-prolog \
    sfst \
    unzip \

RUN (cd ParZu; bash install.sh)

RUN apt-get update && apt-get -y install curl

EXPOSE 5003

WORKDIR /ParZu
CMD python3 parzu_server.py --host 0.0.0.0

Thank you for your help!

I cannot use sudo apt-get to download swi-prolog sfst. The other alternative is to clone the swi-prolog repo and build it. Does anyone have any other solution?

Hello Rico,
i have a naive question. How can I parse file in docker (windows 10)? I tried the following command line but it leads to error.
c:\user> docker run -i rsennrich/parzu python parzu.py -i tagged < sample_input
Then I got an error:

In Zeile:1 Zeichen:54

• docker run rsennrich/parzu python parzu.py -i tagged < sample_input

•                                                  ~
  

Der Operator "<" ist für zukünftige Versionen reserviert.

• CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
• FullyQualifiedErrorId : RedirectionNotSupported

Could you please tell me how to user it in the right way? Thanks a lot in advance!
Best, Tinghui

It is not possible for me to run ./statistics/create_statistics.sh conllfile because then the prolog files are not found.

So I cd into statistics and run ./create_statistics.sh ../conllfile

The first problem is in stats_creator/conll2prolog.py line 70 which uses a python 2 print statement which will not work with Python 3. This can be fixed by changing the line into

print("w({0}, {1}, '{2}', '{3}', '{4}', {5}, {6}).".format(i,pos,token,tag,label,head,morph))

for Python 3.

The second problem is that there is no guard for conll input lines which do not have at
least 11 fields. partA of my converted hamburg dependency treebank has only 10 fields in
line 1378186 so the python program crashes there. This can be fixed by replacing the line
with the split function by:

    fields = line.strip().split()
    if len(fields) < 11:
        print("Line {} has only {} fields, ignored".format(linenr, len(fields)), file=sys.stderr)
        continue
    pos, word, lemma, _, tag, _, morph, _, head, _, label = fields[:11]

(and also adding the linenr counter).

It would be very cool if the server would support processing already tokenised text. For get, a parameter could indicate that the string is whitespace-separated tokens, and for POST requests with JSON, an array of tokens could get passed ass well.

So ideally this would just be another REST parameter in addition to text and format, maybe "input" with possible values "tokenized" and "tokenized_lines" and maybe also "plain", "preprocessed" and "tagged" to support everything the class actually supports.

The page of the ParZu shows the Error 502. Is there any server problem or has the demo been closed?
I need it for an study work at the University of Bonn.

In the faq at line 149 the link to http://ilk.uvt.nl/conll/#dataformat seems to be broken (i get a 404). There is a snapshot of the site available at archive.org, but maybe one could also relocate the article somehow.

I use swipl 8.2.1 and pexpect 4.6.0 on a mac.

Do you have any idea?

Hello,

i am trying to use Parzu from my python programm. Unfortunately I cannot find an explanation how to use the python module. How does the method call look like? Is there anything special to do.
Thanks in advance.

Currently the scripts, like parzu_server.py or parzy.py use the shebang line
#!/usr/bin/python which will always invoke the system-installed python command (which depending on the system may be Python 2 or 3).
However, many users have a per-user python command e.g. to make "python" default to python3 instead of Python 2 or they their own Anaconda installation within their user space where all the python packages are installed and new ones can be installed without administrator access.

Using #!/usr/bin/env python would make use of those per-user python commands but would still use the default /usr/bin/python if no per-user python command exists (essentially just uses what is in the PATH).
