Option 1
Back Up and try rebuild the library: hold down the apple and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over – no slideshows, books or calendars, for instance – but it should get all your albums and keywords, faces and places back.
