Koru search engine

Koru is part of an ongoing research project to investigate how Wikipedia can be utilized to provide intelligent, intuitive information retrieval. Koru is the Māori word for the newborn, unfurling fern frond- it symbolizes growth and evolution[1]

The Koru search engine is part of David Milne's PhD and is still under development.

Operation

Koru

  • expands queries automatically
  • helps guide the user evolve their queries interactively

Interface


Koru search engine with all three panels visible.

The interface is illustrated in the screenshot above. Implementation is based on the AJAX framework, which provides a reactive interface in a web page.

Configurations

There are three possible configurations, which relate to three stages of expected user behavior:

  1. Building an appropriate query. This involves adding and removing phrases until the query and corresponding list of query results satisfies the user’s information need. At this stage two panels are visible: query topics and query results (the leftmost two panels in the screenshot).
  2. Browsing the document list. Once a suitable list of documents is returned, the user must determine the most relevant ones and judge whether they warrant further study. At this point the panels in Figure 1 slide across so that only the rightmost two (query results and document tray) are visible.
  3. In-depth reading of a chosen document. Having located a worthy document, the user then devotes time to actually reading the relevant sections. Here only the documents tray is needed. Anything else would be a distraction.
gollark: > `howsmall`, `howbig`
gollark: It isn't. *All* browsers just say that in the user agent due to poor design of websites back in the day.
gollark: Did you mlock it?
gollark: How do you know it isn't using swap?
gollark: Perhaps just hash the whole thing every 5 minutes, or use an actual error correcting code to detect where errors are.
