While the issue of "truth" is interesting and important, it is also fairly orthogonal to the task of simply extracting what a given page or bit of content claims. (Perhaps not 100% orthogonal in the absolute limit, but generally so.) As absolutely hard as I have gone against the semantic web community at times over the post few years, I do not in the slightest hold a failure to "determine truth" against them. I consider them to have been tilting at windmills as it is, criticizing them for failing to conquer that windmill, which humanity has been jousting with since the dawn of recorded history (and probably beyond), would be a degree of cruel I couldn't entertain. :)
