Hi there, I am trying to use Pikes 

sudo apt-get install openjdk-8-jdk
sudo apt-get install maven

wget https://knowledgestore.fbk.eu/files/pikes/download/pikes-all.tar.gz # Download the full package
tar xzf pikes-all.tar.gz
cd pikes
bash run.sh

After that the server is running and responding 

import requests

endpoint = 'http://35.245.146.92:8011/text2naf?text='

# Make the request to a url
r = requests.get(endpoint)
c = r.content
print(c)

What is b` in from of XML?

b'<?xml version="1.0" encoding="UTF-8"?>\n<NAF xml:lang="en" version="v3">\n  <nafHeader>\n    <fileDesc creationtime="2020-02-24T08:39:46Z" />\n    <public uri="http://pikes.fbk.eu/" />\n    <linguisticProcessors layer="text">\n      <lp name="Stanford CoreNLP" beginTimestamp="2020-02-24T08:39:46.474+0000" endTimestamp="2020-02-24T08:39:46.774+0000" />\n    </linguisticProcessors>\n    <linguisticProcessors layer="naf-filter">\n      <lp name="NAF filter" beginTimestamp="2020-02-24T08:39:46.775+0000" endTimestamp="2020-02-24T08:39:46.775+0000" />\n    </linguisticProcessors>\n  </nafHeader>\n  <timeExpressions>\n    <timex3 id="tmx0" type="DATE" value="2020-02-24" />\n  </timeExpressions>\n</NAF>\n'

But in the server log I see this:

code: 503 for URL: http://api.dbpedia-spotlight.org/annotate

I tried to go to http://api.dbpedia-spotlight.org/annotate

So this seems to be an issue from fcw. In my Docker build, I worked around this by doing the following during build:

git clone https://github.com/fbk/fcw \
  && cd fcw \
  && grep -rl "http://model.dbpedia-spotlight.org/en" . | xargs sed -i 's/http:\/\/model.dbpedia-spotlight.org\/en/https:\/\/api.dbpedia-spotlight.org\/en/g' \
  && git checkout develop \
  && mvn versions:set -DnewVersion=1.0-SNAPSHOT \
  && mvn clean install -DskipTests -Dgpg.skip

Maybe this helps if someone stumbles upon this issue.
