Bibliography Fetch¶

A couple of the notebooks use the 'CHI Papers' data set. This notebook creates that data set from the original sources.

Setup¶

Let's import libraries:

In [1]:

import pandas as pd

In [2]:

import re

In [3]:

import html5lib as html
import requests
from tqdm.notebook import tqdm

Fetching the Index¶

The full list of files in the HCI Bibliography is on the index page. We'll use that to get our file list:

In [4]:

hcibib_root = 'http://hcibib.org'
file_index = requests.get(f'{hcibib_root}/listdir.cgi')

In [5]:

idx_html = html.parse(file_index.text)

Parse the files out of the HTML content itself:

In [6]:

files = {}
bib_re = re.compile(r'^/bibdata/(.*\.bib)')
for link in idx_html.findall('*//{http://www.w3.org/1999/xhtml}a'):
    href = link.get('href')
    m = bib_re.match(href)
    if m:
        files[m.group(1)] = href
len(files)

Out[6]:

1988

Decoding Data¶

Let's get an example file to see what we're dealing with:

In [7]:

ex_path = files['CHI10-1.bib']
ex_file = requests.get(f'{hcibib_root}{ex_path}')
print(ex_file.text[:5000])

%X Both handwriting recognition systems and their users are error prone.
Handwriting recognizers make recognition errors, and users may miss those
errors when verifying output. As a result, it is common for recognized
documents to contain residual errors. Unfortunately, in some application
domains (e.g. health informatics), tolerance for residual errors in recognized
handwriting may be very low, and a desire might exist to maximize user accuracy
during verification. In this paper, we present a technique that allows us to
measure the performance of a user verifying recognizer output. We inject
artificial errors into a set of recognized handwritten forms and show that the
rate of injected errors and recognition errors caught is highly correlated in
real time. Systems supporting user verification can make use of this measure of
user accuracy in a variety of ways. For example, they can force users to slow
down or can highlight injected errors that were missed, thus encouraging users
to take more care.

%X Researchers have developed many models to predict and understand human
performance in text entry. Most of the models are specific to a technology or
fail to account for human factors and variations in system parameters, and the
relationship between them. Moreover, the process of fixing errors and its
effects on text entry performance has not been studied. Here, we first analyze
real-life text entry error correction behaviors. We then use our findings to
develop a new model to predict the cost of error correction for character-based
text entry technologies. We validate our model against quantities derived from
the literature, as well as with a user study. Our study shows that the
predicted and observed cost of error correction correspond well. At the end, we
discuss potential applications of our new model.

%X Dictionary-based disambiguation (DBD) is a very popular solution for text
entry on mobile phone keypads but suffers from two problems: 1. the resolution
of encoding collision (two or more words sharing the same numeric key sequence)
and 2. entering out-of-vocabulary (OOV) words. In this paper, we present
SHRIMP, a system and method that addresses these two problems by integrating
DBD with camera based motion sensing that enables the user to express
preference through a tilting or movement gesture. SHRIMP (Small Handheld Rapid
Input with Motion and Prediction) runs on camera phones equipped with a
standard 12-key keypad. SHRIMP maintains the speed advantage of DBD driven
predictive text input while enabling the user to overcome DBD collision and OOV
problems seamlessly without even a mode switch. An initial empirical study
demonstrates that SHRIMP can be learned very quickly, performed immediately
faster than MultiTap and handled OOV words more efficiently than DBD.

%X Information foraging models have predicted the navigation paths of people
browsing the web and (more recently) of programmers while debugging, but these
models do not explicitly model users' goals evolving over time. We present a
new information foraging model called PFIS2 that does model information seeking
with potentially evolving goals. We then evalua

These files have line prefixes that indicate different fields. Fields can continue across multiple lines. A blank line separates records. So we need to parse this.

We're going to write a function that processes a file to do exactly that. It is going to be a Python generator, so it can be used in a loop but doesn't build a whole list.

In [8]:

_c_re = re.compile(r'^%([A-Z*]) (.*)')
_blank_re = re.compile(r'^\s*$')
_bib_codes = {
    'T': 'title',

Now we have a file record extracted!

Extracting CHI Papers¶

Now we want to get all the CHI papers.

Let's define a regex to match a CHI paper file name, CHI followed by at least a digit:

In [10]:

chi_re = re.compile(r'^CHI\d')

And get the CHI files:

In [11]:

chi_files = [k for k in files.keys() if chi_re.match(k)]
chi_files

Out[11]:

['CHI16-2.bib',
 'CHI16-1.bib',
 'CHI15-1.bib',
 'CHI15-2.bib',
 'CHI02-1.bib',
 'CHI14-1.bib',
 'CHI14-2.bib',
 'CHI04-2.bib',

 'CHI98-2a.bib',
 'CHI98-2b.bib',
 'CHI98-2c.bib',
 'CHI98-2d.bib',
 'CHI99-1.bib']

Now we're going to a list of all the records in all the CHI files:

In [12]:

chi_records = []
for fk in tqdm(chi_files):
    path = files[fk]
    data = requests.get(f'{hcibib_root}{path}')
    for rec in parse_bib(data.text):
        chi_records.append(rec)
len(chi_records)

Out[12]:

13422

Now we're going to turn that all into a Pandas data series:
