Award winning code
Me and
Yuwei had a fun day at
hhhmcr
(
#hhhmcr) and even managed to put
together a prototype that won the first prize \o/
We played with the
gmp24 dataset
kindly extracted from Twitter by
Michael Brunton-Spall
of the
Guardian into
a convenient JSON
dataset. The idea was to find ways of making it
easier to look at the data and making sense of it.
This is the story of what we did, including the code we wrote.
The original dataset has several JSON files, so the first task was to put them
all together:
#!/usr/bin/python
# Merge the JSON data

# License: WTFPL version 2 (http://sam.zoy.org/wtfpl/)
import simplejson
import os
res = []
for f in os.listdir("."):
if not f.startswith("gmp24"): continue
data = open(f).read().strip()
if data == "[]": continue
parsed = simplejson.loads(data)
res.extend(parsed)
print simplejson.dumps(res)
The results however were not ordered by date, as
GMP had to use several accounts to twit because
Twitter was putting Greather Manchester Police into
jail for generating
too much traffic. There would be quite a bit to write about that, but let's
stick to our work.
Here is code to sort the JSON data by time:
#!/usr/bin/python
# Sort the JSON data

# License: WTFPL version 2 (http://sam.zoy.org/wtfpl/)
import simplejson
import sys
import datetime as dt
all_recs = simplejson.load(sys.stdin)
all_recs.sort(key=lambda x: dt.datetime.strptime(x["created_at"], "%a %b %d %H:%M:%S +0000 %Y"))
simplejson.dump(all_recs, sys.stdout)
I then wanted to play with
Tf-idf for extracting the most
important words of every tweet:
#!/usr/bin/python
# tfifd - Annotate JSON elements with Tf-idf extracted keywords

import sys, math
import simplejson
import re
# Read all the twits
records = simplejson.load(sys.stdin)
# All the twits by ID
byid = dict(((x["id"], x) for x in records))
# Stopwords we ignore
stopwords = set(["by", "it", "and", "of", "in", "a", "to"])
# Tokenising engine
re_num = re.compile(r"^\d+$")
re_word = re.compile(r"(\w+)")
def tokenise(tweet):
"Extract tokens from a tweet"
for tok in tweet["text"].split():
tok = tok.strip().lower()
if re_num.match(tok): continue
mo = re_word.match(tok)
if not mo: continue
if mo.group(1) in stopwords: continue
yield mo.group(1)
# Extract tokens from tweets
tokenised = dict(((x["id"], list(tokenise(x))) for x in records))
# Aggregate token counts
aggregated =
for d in byid.iterkeys():
for t in tokenised[d]:
if t in aggregated:
aggregated[t] += 1
else:
aggregated[t] = 1
def tfidf(doc, tok):
"Compute TFIDF score of a token in a document"
return doc.count(tok) * math.log(float(len(byid)) / aggregated[tok])
# Annotate tweets with keywords
res = []
for name, tweet in byid.iteritems():
doc = tokenised[name]
keywords = sorted(set(doc), key=lambda tok: tfidf(doc, tok), reverse=True)[:5]
tweet["keywords"] = keywords
res.append(tweet)
simplejson.dump(res, sys.stdout)
I thought this was producing a nice summary of every tweet but nobody was
particularly interested, so we moved on to adding categories to tweet.
Thanks to
Yuwei who put together some useful keyword
sets, we managed to annotate each tweet with a place name (i.e. "Stockport"),
a social place name (i.e. "pub", "bank") and a social category (i.e. "man",
"woman", "landlord"...)
The code is simple; the biggest work in it was the dictionary of keywords:

All these scripts form a nice processing chain: each script takes a list of
JSON records, adds some bit and passes it on.
In order to see what we have so far, here is a simple script to convert the
JSON twits to CSV so they can be viewed in a spreadsheet:
#!/usr/bin/python
# Convert the JSON twits to CSV
# (C) 2010 Enrico Zini <enrico@enricozini.org>
# License: WTFPL version 2 (http://sam.zoy.org/wtfpl/)
import simplejson
import sys
import csv
rows = ["id", "created_at", "text", "keywords", "placename"]
writer = csv.writer(sys.stdout)
for rec in simplejson.load(sys.stdin):
rec["keywords"] = " ".join(rec["keywords"])
rec["placename"] = rec.get("placename", "")
writer.writerow([rec[row] for row in rows])
At this point we were coming up with lots of questions: "were there more
reports on women or men?", "which place had most incidents?", "what were the
incidents involving animals?"... Time to bring
Xapian
into play.
This script reads all the JSON tweets and builds a Xapian index with them:
#!/usr/bin/python
# toxapian - Index JSON tweets in Xapian

Neat! Now that we have a proper index that supports all sort of cool things,
like stemming, tag clouds, full text search with complex queries, lookup of
similar documents, suggest keywords and so on, it was just fair to put together
a web service to share it with other people at the event.
It helped that I had already written similar code for
apt-xapian-index and
dde before.
Here is the server, quickly built on
bottle. The very last line starts
the server and it is where you can configure the listening interface and port.
