Known-item information seeking is the easiest to understand. In a known-item task, the user:
- Knows what they want
- Knows what words to use to describe it
- May have a fairly good understanding of where to start
In addition, the user may be happy with the first answer they find (though not always) and the task may not change significantly during the process of finding the answer.
. . .2. Exploratory
In an exploratory task, people have some idea of what they need to know. However, they may or may not know how to articulate it and, if they can, may not yet know the right words to use. They may not know where to start to look. They will usually recognise when they have found the right answer, but may not know whether they have found enough information.
In this mode, the information need will almost certainly change as they discover information and learn, and the gap between their current knowledge and their target knowledge narrows.
. . .3. Don’t know what you need to know
The key concept behind this mode is that people often don’t know exactly what they need to know. They may think they need one thing but need another; or, they may be looking at a website without a specific goal in mind.
This mode of seeking information occurs in a number of situations:
- Complex domains such as legal, policy, or financial. For example, a staff member may want to know how many weeks maternity leave they are entitled to, but may need to know the conditions surrounding that leave. We should read the terms and conditions of new products and services as there maybe important restrictions, but they are too often buried in legal garble that we don’t read.
- Any time we wish to persuade the user. For example, we would love people to know more about information architecture and usability, but they often don’t know that the concepts even exist. They may think they want to know how to make an accessible nested fly-out menu; we think they need to know more about organising the content properly.
- Unknown domains. For example, when someone is told by friends that he or she should check out a new service, product or website, but does not yet know why he or she would want to know about it.
- Keeping up to date. People often want to make sure they keep up to date with what is happening within an industry or topic, but are not looking for a specific answer.
. . .4. Re-finding
This mode is relatively straightforward—people looking for things they have already seen. They may remember exactly where it is, remember what site it was on, or have little idea about where it was. A lot of my personal information seeking is hunting down information I have already seen. I don’t know how prevalent this is, but discussions with others indicate that I am not alone.
