Lava displays multiple levels of a corpus in a three-dimensional environment. Clicking on a document within the corpus expands the Lava visualization in a ring to further explore terms within their context.

Getting Started

When you first arrive to the Lava tool you will see one of two possible screens:

Lava without a pre-loaded corpus. See loading texts into Voyeur for help on how to proceed.

Lava with a pre-loaded corpus. You were probably given a URL that included the corpus, or you’re viewing a page that has an embedded Voyeur tool in it. If you prefer, you can also start without a corpus.

Interface Elements

Lava includes the standard set of interface elements (see image to the right). For more help with these see the Voyeur Tools Standard Interface Elements page.

Reading the tool

When you first launch Lava with a corpus of multiple documents, you will see what looks like a black pole. If you launch with a corpus of a single documents, Lava will look like a black disc. Hovering on sections of this pole will illuminate the names of different documents within the corpus.

Hovering over a document

Click on this illuminated section, Lava will expand as a coloured ring, each colour representing a high frequency term. Hovering over one of these sections will display the term that it represents.

Hovering over the ring

Clicking on the term will expand it as a coloured arm out from the centre. Hovering over different sections of this arm will show the term in the context of the document.

Hovering over the arm

Clicking other sections of the pole will expand other documents within the corpus displaying multiple visualizations at once.

Expanding other documents


Like all Voyeur tools, Lava can be reused in a variety of ways:

  • create a link that is specific to the corpus and options that are currently being used
  • embed the current corpus and options as a tool in an external page
