Word/PDF CV importer library

We have a job portal and would like to allow users to import their existing CV into our system. We want to support .doc, .docx and pdf for start. Basically the user will upload their CV and the system will parse it, identify things like education & qualification, career history, technical skills and create them in the database. The site is in PHP but the library can be in java or similar as long as it can be called from PHP (we are running on Linux). An API will be ideal. In your bid please avoid please explain how you will implement and save me any marketing bias. Proposals without technical explanation and auto-bids will simply be ignored.
