How to understand the result returned by "nm" command

I used nm command to inspect the function names in a .so library. And the result I got is like this: 00009634 T _Z24ICTCLAS_ParagraphProcessPKciPc9eCodeTypeb 00009764 T _Z25ICTCLAS_ParagraphProcessAPKciRi9eCodeTypeb 00009b24 T _Z26ICTCLAS_ParagraphProcessAWPKcP17tagICTCLAS_Result9eCodeTypeb Actually there are functions called ParagraphProcess and ParagraphProcessA. But how to interpret the prefix(_Z24ICTCLAS_) and suffix(PKciPc9eCodeTypeb) and the address-like string(00009634) at the start of the line?
