I tried in several browsers and I get similar errors as below:

502 Bad Gateway

Hi,

Is there any support for legacy sql systems like mysql and oracle

502 Gateway Error in all queries

While running quepy nltkdata /some/pathdownloads the resources "wordnet" and "maxent_treebank
_pos_tagger", trying to run the applicaion gives the following error:

Resource u'taggers/averaged_perceptron_tagger/averaged_perceptron_tagger.pickle' not found. Please use the NLTK Downloader to obtain the resource: >>> nltk.download()

I believe this is because of the perceptron tagger being made the default tagger in the nltk project, which is a dependency for quepy.

my conda env is python3,but it doesn't work,i can't import the quepy.when i create the env python2,it can work.it may not support the python3?

Please help me in resolving this error so that I can use this module in my project

I am facing some issues in understanding the api usage since I couldn't find enough examples. Besides the existing examples are unfortunately not very clear. It would be a great help if successful users of this framework could provide links to their projects.

A few files where renamed and the docs were not changed to reflect this.
In particular, the tutorial name a file parsing.py that does not exists because it was renamed to basic.py.
This error should be fixed and a review of the docs should be made.
Anybody is welcome to submit pull requests for this!

When I ask "What is the capital of Massachusetts?" it fails to find an answer because it thinks Massachusetts is a country.

After installing with pip,It doesn't found any module quepy,(on windows)->and on "quepy --version" it opens up the quepy file in text editor.
please help me,I tries different way,but not any work for me.

I just installed quepy to start working with some examples as shown in the tutorials. But I get the following errors while running main.py.

Also this is how i set he nltk_data variable in settings.py:

# NLTK config
NLTK_DATA_PATH = "/home/gurupad/nltk_data"  # List of paths with NLTK data

Can someone help me out?

How can I sort a query result set. similar to SELECT ... {...} ORDER BY ?var

I am constantly facing errors in this code, could anyone help me ?
I declared my ontology as filename in the settings.py folder,
what would be the best way to import ontology made in system to be used in quepy to generate queries ??

That, docopt is missing as a requirement

MQL will not be available in June 30, 2015.
It will be replaced with Wikidata.

See post here

In the example given on the Quepy README.rst, before

python examples/dbpedia/main.py "Who is Tom Cruise?"

, an instruction to configure settings.py (in examples/dbpedia) so that it points to the path where the nltkdata is placed, should be given.

MQL write API has been retired and freebase now exists as a data dump of 1.9 billion Freebase triples in N-Triples RDF format, available on the developers page. So is it preferable to remove the related code or keep it as legacy?

Hi folks, is there any chance there's a simple way to implement other languages support? Cheers

as there is no quepy.py file then how can we start a new project
I have tried with quepyapp.py file to start a new project but nothing happened

"$ quepy.py startapp dbpedia"
how to do this

Hi in the online demo given at http://quepy.machinalis.com/ I'm getting result for "what is the plot of Titanic?" but not for "what is the plot of titanic?"

Is this expected?

As of now there are only triples inside WHERE{}. Including this filtering can increase the semantics in the search.
eg) List the details of Actors other than Tom Cruise?
which filters Tom Cruise and displays the result of other actors.
Implementing this is a great achievement against keyword based which will only details of Tom Cruise which is opposite of what the user wants.

I am trying to create my own RDF module based on dbpedia in Chinese.

In my dsl.py, we created something like:

HasKeyword.relation = "rdfs:label"
HasKeyword.language = "zh"

However, when I created two RDF modules simultaneously in the constructor of main class:

self.dbpedia = quepy.install("dbpedia")
self.zhwiki = quepy.install("zhwiki") # Chinese version of dbpedia

I found that the latter module that I created will always override the first one.

In particular, the dsl.py for dbpedia look likes:

HasKeyword.language = "en"

And the variable "HasKeyword.language" will be overrided as "zh"

Is there any good way to resolve it?

I'd like to have support for key value store and document store storage backend:

• https://github.com/stephan-hof/pyrocksdb
• https://api.mongodb.org/python/current/
• https://pythonhosted.org/CouchDB/

This would be awesome for interconnected knowledge graphs retrieval of information in natural language.

I'm willing to help this happen.

Unmaintained? Last commit to master was more than 1 year ago.

The query "What is Pokémon?" silently drops the é and then tells me there is no result in the database for "Pokmon". "What is Tyranitar?", on the other hand, got me this gem from Freebase:

are one of the 493 fictional species of Pokￃﾩmon creatures from the multi-billion-dollar Pokￃﾩmon media franchise, designed by Ken Sugimori. The purpose of Tyranitar in the games, anime, and manga, as with all other Pokￃﾩmon, is to battle both wild Pokￃﾩmon￢ﾀﾔuntamed creatures that characters encounter while embarking on various adventures and tamed Pokￃﾩmon creatures owned by Pokￃﾩmon trainer.

In case Github eats them, the two middle characters are U+FFC3 HALFWIDTH HANGUL LETTER AE and U+FFA9 HALFWIDTH HANGUL LETTER RIEUL - how U+00E9 LATIN SMALL LETTER E WITH ACUTE ended up as that is beyond me. (It may be a bug in the database, because the query "What is Pikachu?" gets back a correctly formatted page.)

Quepy provides support for cypher query languages?

Quepy provides support for cypher query languages? do you some advices?
thank you in advance~

@j0hn @dmoisset I am trying to build SPARQL queries using QUEPY and was looking for any example where you guys have used FILTER clause. I did not find any. Could you please provide a sample code or a tutorial. This issue has also been reported by another user #44.
Moreover, I tried to build queries extracting multiple items but query is not being generated. For example, i was trying to generate query for "list proteins with symbols and chromosome where protein symbol is ACT" How can I build query like this?
3- To generate a federated query you have to join the query with SERVICE clause. Does quepy support for joining (SERVICE) clause.

I have been adding functions to, for example, ask the release date of a song. However, there are TWO other functions for this, except for different domains, movies and TV shows. How can we deal with this? Can you add some function that can determine whether the movies query yields no results, so try the TV show query, then the song query? Or is there a way to show all query results?

To work on Windows, you'll need a quepy.bat wrapper for the quepy Python script. All the other things in my Scripts directory have them, but I'm not sure what is needed to get the installer to create it (or if you have to do it yourself). I installed using pip, not easy_install, if it makes a difference.

Word.prob seems to be unused.
It should be checked that this is so and the "prob" attribute and related code removed.

Credit to @dmoisset for spotting it

I have installed as so:
pip install quepy

Then:

sivan@metal:~/icrav/code$ quepy
Traceback (most recent call last):
File "/home/sivan/icrav-venv/bin/quepy", line 27, in
from docopt import docopt
ImportError: No module named docopt

It appears that this fixes it:
pip install docopt

so docopt needs to be added to the requirements.txt

Hola, Todos los ejemplos tienen la siguiente sintaxis
SELECT DISTINCT {select} ....
por ejemplo:
SELECT DISTINCT ?x1 WHERE {
?x0 rdf:type foaf:Person.
?x0 rdfs:label "Tom Cruise"@en.
?x0 rdfs:comment ?x1.
}

Mi pregunta es, si es posible agregar mas variables en el SELECT
por ejemplo:
SELECT DISTINCT ?x0 ?x1 WHERE {
?x0 rdf:type foaf:Person.
?x0 rdfs:label "Tom Cruise"@en.
?x0 rdfs:comment ?x1.
}

Saludos
