Only 2904 questions were processed in our run on 20th November. Everything henceforth works on this, and nuffin else. FIX THAT!

Very interesting work and thanks for sharing the codes.
I wanna reproduce the experiments of paper "Learning to Rank Query Graphs for Complex Question Answering over Knowledge Graphs" , and wonder would you please provide guidance for reproduction.
Thank you again and waiting for your reply.

Hello,
Thanks for sharing your work. I am trying to set up the system for benchmarking purposes, however, I cannot run the SPARQL parsing server. I cannot find the file/lib used in your system. Any guides will be appreciated.
Thanks

Hello,

I am encountering the same problem mentioned in issue #16 but it is not clear what the solution is.
This is happening at step 5 in the Readme.md, python data_creation_step1.py.

Note that the Python environment krantikari is built according to the provided environment.yml but there is no file data_creation_step1.py. Therefore, running (with sysargs)

(krantikari) user@host:/KrantikariQA$python data_creator_step1.py 0 -1 lcquad

results in the following output

Traceback (most recent call last):
  File "data_creator_step1.py", line 160, in <module>
    _predicate_blacklist=pb, _relation_file={}, return_data=False, _qald=False)
  File "data_creator_step1.py", line 71, in run
    cd_node = cd.CreateDataNode(_predicate_blacklist=_predicate_blacklist, _relation_file=_relation_file, _qald=_qald)
  File "/app/KrantikariQA/datasetPreparation/create_dataset.py", line 27, in __init__
    self.create_subgraph = es.CreateSubgraph(self.dbp, self.predicate_blacklist, self.relation_file, qald=_qald)
AttributeError: module 'datasetPreparation.entity_subgraph' has no attribute 'CreateSubgraph'

Hopefully this description provides all the details requested in this comment

I would also point out that there is no CreateSubgraph class in entity_subgraph.py, although it is called in both datasetPreparation/create_dataset.py and server.py which both do

from datasetPreparation import entity_subgraph as es

and each will attempt the same pattern:

self.create_subgraph = es.CreateSubgraph(self.dbp, self.predicate_blacklist, self.relation_file, qald=_qald)

and

subgraph_maker = es.CreateSubgraph(dbp, predicate_blacklist, {}, qald=False)

, respectively.

Any advice?

Hi, sorry to trouble you again.
When I run : CUDA_VISIBLE_DEVICES=1 python corechain.py -model slotptr -device cuda -dataset lcquad -pointwise True

The error line: loss.backward()
My GPU memory : 10G.

Thank you for your help.

Lemmatize everything while converting it to IDs (nlutils).

Hi, Sorry to trouble you. I find a error:
AttributeError: module 'datasetPreparation.entity_subgraph' has no attribute 'CreateSubgraph'

Would you like to help me?

Does dot product in the network file at line 236,237 need to be normalized with the value of the vector?

• Only 2904 questions parsed (check why)
• False paths include weird/metadata predicates (debate whether to remove them or not)
• Y labels are 0/1 as of now. (find partially correct paths and rate them as such)
• Pick up False labels with partially correct paths too (as opposed to purely random)

Sorry, trouble you, again.
in corechain.py: every epoch, I find the maximum i_batch is 87.
Are there eror on my local ?

thank you.

So that it discounts all but the trailing zeros.

We don't handle ask queries whose answers depends upon whether this query will fetch any answer; only handle the ones which enquire whether THIS triple exists.

Eg. of queries we don't handle yet:

ASK WHERE {
        res:James_Bond dbo:spouse ?uri . 
}

Started Redis server and still the connection gets refused when running the file krantikari.py
