New network visualizations in 3D

Everything is better in 3D! Network visualizations provide powerful ways to convey a lot of information at once, but even with a small set of nodes they can become confusing quickly. To make it easier to explore the associations between words in a network, a new three-dimensional visualization method is now available. You can try it out yourself by clicking the visualize menu at the top of this page and selecting the 3D Network method under the options button ().

An example for the forward association network of word is shown on the right. The new visualizations are interactive. You can zoom and pan to change the view but also click on each word to center them. Similar to other visualizations you're able to search for multiple words at once by adding a comma between them in the search box. There's also an option shown for each network to animate it similar to the illustration.
The different colors correspond to clusters of words that are related in some way. The clusters (aka communities) are calculated for each network visualization and will thus depend on the search terms used. In the example, we see words with similar meaning like game, games, and play clustered together.

Feedback is always welcome but note that some of the features are still experimental and might not work on every browser. Interacting with the graph should work on a computer but might be less ideal on phones, tablets, or other touch devices. The functionality might be extended in the future to explore the networks in VR if I get a hand on a headset.
Credit goes to Vasco Asturiano for developing the 3d-force-graph library that's making this possible and to Corneliu Sugar for making the jLouvain community detection library available.

Small World of Words at MoD Hedonism Exhibition

The Small World of Words project will be featured in the "Its my pleasure" digital installation by Owen Churches as part of the Hedonism Exhibition at the brand new Museum of Discovery (Mod) in Adelaide, Australia.

This installation explores the how recommendation engines affect our lives. Whether we are using them to navigate the news, find friends or digest dinner, there is a sense in which we are always asking for the algorithm to deliver us the same thing: our greatest pleasures.
To find out more, check out Owen's blog post or try out the digital installation online.

Entry to the exhibition is free and runs from May 2019 to November 2019. Check out the museum website for more information if you'd like to visit.

English Small World of Words study published

It is my pleasure to announce that the English Small World of Words (SWOWEN-2018) study is now published in Behavior Research Methods. It consists of 3.6 million word association responses to over 12,000 cue words. Nearly 90,000 volunteers have contributed to what is now the largest publicly available resource about the mental lexicon in English. It covers over 80% of the words we use in daily language, and hopefully we can increase that number in the coming years.
In the Behavior Research methods paper we explain how these data can be used to accurately predict how we process words and their meaning through a mechanism of spreading activation, in which meaning is derived by direct and indirect connections a word has with other words in networks similar to those you can visualize on this website.

Thanks again to all volunteers and colleagues who helped making this possible.

Rioplatense project in the news

In the last few months, the Rio Platense project has been growing steadily. So far nearly 20,000 people have contributed to the first linguistic resource of this kind for Spanish speakers in Uruguay and Argentine.
If you speak Spanish you might want to learn more about the Rio Platense Small World of Words project by checking a new El Pais news article or listening to a broadcast from Sarandi Radio where you hear more from the lead investigator Álvaro Cabana.

The Small World of Words in Bahasa Indonesia

Halo! Apa kabar? Yes, that’s Indonesian language! Maybe some of you have never heard about Indonesian language or Bahasa Indonesia, but this language is spoken by the fourth most populated country in the world, making it as the seventh most spoken language in the world after French (according to Ethnologue, 2017, 20th edition).

Indonesia as an archipelago country has hundreds or even thousands of spoken languages. Bahasa Indonesia has been used as lingua franca, not only among multilingual Indonesians from different islands and provinces, but centuries ago it was used as a trading language between the locals and the traders.

This rich history makes Bahasa Indonesia is a unique language composed of words coming from different languages all over the world, such as Dutch, Arabic, and Portuguese. With these unique features, it will be interesting to compare the association network of Bahasa Indonesia with other languages.

The lead investigator on this project is Farah Djalal. Farah is an Indonesian lecturer and researcher from Bina Nusantara University, who is interested in her own native language and on how people use language to categorize objects. If you want to know more or have any questions (either in Indonesian or in English) please do not hesitate to get in touch: [email protected].

Selamat mencoba!

Network visualizations

The network visualizations have been updated and now include bubble plots and various way to represent the word assocation data as a network. It's now possible to specify a forward, backward or related network. In each case, they give you a slightly different perspective. For forward networks, the links indicate the responses to a cue word. For the backward network, the links indicate the opposite relations, namely the cue words for the responses. The related networks takes into account how similar two words are by calculating how similar their responses are. To change the visualization type, simple press on the option icon .

Example of a forward network visualization searching for the words man, woman, girl and boy.

You can now also look for multiple key words by entering words in the search box divided by commas. The figure shows an example. You'll also notice different colors in this network. These colors correspond to tightly connected regions in the network. These clusters or "communities" of words, are obtained using the Louvain community detection algorithm and are determined in an automatic (unsupervised) fashion. The nice thing about this style of visualization is that it automatically shows how multiple words are related and what links contribute to this relatedness.

You can also explore these networks interactively, by clicking their label and drag the nodes by holding down the left mouse-button. Another fun way to explore the mental dictionary and you don't feel inspired is by choosing a random word. Just press the icon.

New version of Small World of Words now online

After 6 years, the Small World of Words project is moving to a new home and an entirely new website. Most pages from are now available at the new domain If you link to the project, please update the URL.

The new website aims to make things more accessible for everyone who's interested in words and language by providing easy lookup and visualization tools. While still a work in progress, you can now lookup words in different languages and access most parts of the website in your own language. Moreover, the dictionary will now reflect an up-to-date snapshot of the lexicon. Besides getting to play with the data collected in this project, the word association game has also been improved to work better on mobile devices and a couple of languages have been added to the project (Chinese, Italian, Portuguese and Russian), so give it a go.

In the coming months the visualization tools will be further improved and the research page will be updated as well.
In the mean time, access to the data and some additional visualizations remain accessible at the research page. Suggestions or feedback are always much appreciated, just mail [email protected].

Detailed images of the mental lexicon

A new visualization shows the entire mental lexicon in English (or at least the 7,000 words collected so far). Node size indicates how important a node is in terms of incoming links (in-strenght). The transparancy of the edges is indicated by edge-betweenness.

Notice the emergence of a handfull of hubs in the lexicon. The hubs are visible as large red nodes and indicate which nodes are central in the network: work, love, food (...almost matching the Maslow's hierarchy of needs). A more detailed image is available here.
