dm_fts_parser equivalent in SQL Server 2005

Question

Is there a way to get the synonyms of the words in an expression, in SQL Server 2005? In SQL Server 2008 this can be done using dm_fts_parser function, but this one does not exist in 2005.

EDIT: I found that there is a file that indicates the words used by Thesaurus, in %ProgramFiles%\Microsoft SQL Server\MSSQL.1\MSSQL\FTData and also the noise words, but there is nothing there regarding the Inflectional expansions words.

Thanks!
