I believe you're thinking of the wrong context, Symantec (the company, as in Norton) vs the indexing and usage of semantic web metadata about files stored on your machine, in this case, in your own home folder by default. this actually gives you the ability to search through your files by various methods, including tags, timestamps, and the source of the file just to name a few, instead of just searching by filename or type, giving you the ability to find what you're looking for in your home folder alot faster. I'd advise you to look further into it here: http://nepomuk.kde.org/discover/user before you jump to any conclusions about this.
