What is the difference between route aggregation and route summarization?

In my understanding of these terms they are essentially the same. Route aggregation and summarization is a method that is used to generate a more general route. Therefore if an ISP has several class C address ranges these can be advertised as one common route. This reduces the burden of upstream routers. To use aggregation you must use classless addressing and use a routing protocol such as OSPF. An in-depth explanation can be found on the Netcraftsmen Web site.
