Some post their internal technical documentation, including documents that run many pages. Some companies strive to capture problems and solutions from their support call logs and post these as knowledge base articles. Some use databases engines of varying complexity to store the knowledge topics. Most simply create and post discreet HTML files. Web knowledge bases also exhibit extremes of quality in terms of information design and accessibility.
Some companies post documents that are excellently written, designed, and formatted.
Some also provide a hierarchical organization and table of contents . The figure illustrates this wide spectrum of web knowledge bases as they exist today, from simple one-page FAQs to the most complex knowledge engineering systems built with artificial intelligence. On this scale, low-end knowledge bases would be those containing only FAQs and perhaps existing documentation, placed on the web with little or no effort at organization. Mid-range knowledge bases might be considered those that have gone through a development process, including audience analysis, planning, and design. They would include more information than the low-end specimens, and would certainly provide a search engine as a means of access.
