Where have all the filters gone?

Mark Bennett at New Idea Engineering – Where have all the filters gone?:

„Through various mergers and acquisitions, the three main vendors for commercial document filters are now owned by companies who are already selling their own search products.

[…] The 3 top commercial filters being used now are:

  1. Stellent [Outside In Technology] – Now part of Oracle, who now sells „search“
  2. KeyView – Now part of Autonomy, a Tier-1 search vendor
  3. Microsoft IFilter Framework (part of some Microsoft products) – Microsoft is also pushing their own search technology.“

The IBM WebSphere Portal Document Conversion Services are building on Oracle Outside In Technology.
