Email and World Wide Web have great attractions - but the sheer volume
of information can become intimidating.
A text database will index every word in every one of thousands-to-millions of documents making each one instantly retrievable simply by typing in combinations of words it contains. Suddenly information which was safely out of reach in places like libraries is available directly from the desktop.
The drawback is that searches can either swamp users with much too much
information, or completely miss what the user is looking for. To avoid this
use free text retrieval combined with traditional classification schemes
and controlled description vocabularies.
Computer conferencing enables geographically dispersed groups of people
to carry on written conversations 'threaded' by topic. People can contribute
to these electronic conversations at any time of their convenience ('asynchronous'
unlike 'synchronous' videoconferencing, for example, where everyone must
be there at the same time) either by starting topics of their own, or replying
to an already existing conversational thread.
The benefit is that people can communicate with each other in their own
time in a consistent and focused way. Results should be more useful information
exchange, more informed decisions and better aligned actions.
The danger is that the signal to noise ratio is very low as chat, confusion
and repetition take over from focused collaborative thinking and discussion.
In order to avoid this problem groups need to agree some structural
elements to their conversations. e.g. major topics and sub-topics. Moderators
need to be appointed to stimulate conversation through effective questioning
and to make sure people stick to agreed topics. Topics must be periodically
summarised in order to give existing members overviews of what they said
and to update new members.
Filters select and screen out items from email and text databases such
as the World Wide Web by comparing document text with user-defined word
combinations.
They can reduce the number of items to look at - however filters can screen
out items for which the user never thought to ask. Agents can bring simply
bring in more unwanted material ironically causing greater expense in both
time and money.
These tools should be used, if possible, in conjunction with classified
information bases, as well as being amended to take into account new vocabularies
and information types -- a process which takes a lot of expert human work.
Also, steps must be taken so that serendipity is not screened out of the
information acquisition process.
