IBM has bought Datacap Inc, a document capture software vendor it's partnered with for years. Terms were not disclosed. Companies use Datacap's widgetry to extract unstructured data from stuff like invoices, claim forms and tax returns, reducing paper costs, eliminating manual errors and meeting compliance regs. IBM means to use it to help organizations digitize their information, particularly paper-intensive industries such as healthcare, insurance, government and finance. The outfit claims 200 customers including BlueCross BlueShield of Arizona, Goodyear Tire & Rubber and the Dutch Tax Officer. IBM Software intends to integrate Datacap into its enterprise content management business.
