oncewasacreek: a words-eye view

Time now for something completely different.

This site has reached a point where I am starting to look back, usually with some degree of bemusement, at all that I have written and done over the last two years. For a while now I’ve been meaning to overhaul the site’s structure to better serve the unexpected array of topics that I have ended up covering. But invariably, something more interesting captures my attention. This post is a case in point.

Recently I have been playing with network graphs as a way of visualising concepts and data. Networks are used as an analytical tool across many branches of science, because just about any phenomenon can be understood at some level as a system of discrete but inter-related entities (or nodes, in network-speak). Perhaps the most obvious examples are social groups and computer networks, but a myriad of other things, from gene sequences to ecosystems to economies, have been modelled and explored with the help of network theory. (Check out this page for a some examples of network visualisations.)

Networks are also useful for analysing text, because they can show relationships among words, such as which words occur together most frequently. And the best bit is that we can get computers to do all the counting. We still need to tell the computer which words to look out for, but thankfully there are dictionaries and word-recognition tools that do much of this work as well.

I wanted to have a go at analysing some text, so I found some software1 and fed it a collection of eleven of my own essays from this website.2 The result, shown below, is a kind of word-map of the topics covered by the eleven articles. In this case, the topics are limited to the names of people and locations, simply because these are much easier to identify than other kinds of topics. In the future, I hope to bring other topics (floods, maps, roads, etc.) into the mix.

The network of all people and places mentioned in the eleven articles. Node size reflects term frequency, and line thickness reflects the strength of co-occurrence. Hover over the image to see the network with the labels removed.

  1. There are various packages out there, some free and some commercial, but the one that I used is called KNIME. It has an intuitive graphical interface, which means you don’t need to know any code.
  2. The essays were: A history of Gregory Park, John Olxey and the chain of ponds, Milton: Brisbane’s western frontier, The waters of Milton, Bottles and cans (an adventure in suburban archaeology), The broken lands of Toowong, Topography shock: postcards from the south, The history of the Coronation Drive Office Park, and the three installments of Uncovering Langsville Creek.

The history of the Coronation Drive Office Park

This post is all about the part of Milton bounded by the railway, Cribb Street, Coronation Drive and Boomerang Street. If you live in Brisbane, it’s a place that you have probably passed many times without really noticing. From Coronation Drive it presents as a row of office buildings and some Jacarandas; from the train, as a car park and some Moreton Bay figs. From within, the site feels like a secluded, shady village. Interspersed with the eight office buildings and fig trees are a tennis court, a childcare centre, a multi-level carpark, an open carpark, cafes, and various shops including a Flight Centre and a real estate office. This site is known (to those who know it as anything at all) as the Coronation Drive Office Park.

The Coronation Drive Office Park is bounded by Cribb Street, the railway line, Boomerang Street and Coronation Drive.

The Coronation Drive Office Park covers 4.5 hectares and is bounded by Cribb Street, the railway line, Boomerang Street and Coronation Drive.

AMP Capital, which manages of the majority of the site,1 are considering the next stage of its development. Before commencing this development, AMP Capital wanted to learn more about the site’s past. They asked me if I would like to do some research, and I jumped at the opportunity. After several weeks plumbing the depths of Trove, the Brisbane City Archives and various other sources, I produced a report documenting the history of the Coronation Drive Office Park.

You can download the report here (it’s about 13MB — apologies for the big download), but for a shorter, more web-friendly version of the story, read on below. Continue reading


  1. Except for half a hectare at the corner of Coronation Drive and Cribb Street, the site is owned by AMP and Sunsuper.
