EMBL-EBI and others had some RDF-related effort to provide machine readable abstracts, which I thought was a really cool idea.
IMHO, the biggest problem with papers is politics and reviews. In many top journals like Nature there's no double-blind review (actually in Nature it's now optional but big groups never use it). And even if there was double-blind review, referees have no skin in the game. So the usual outcome is to get reviewed by a big name in your field, who is actually interested in controlling research trends and killing "competitors".
This is hindering progress and hurting new ideas. For example, proponents of Alzheimer's disease being caused by an infection or dysbiosis have had a hard time to do research, get grants and publish articles during the last 2 decades. Despite their theory is able to explain the etiology quite well, unlike competing alternatives.
Another problem is that to publish in good journals you need cool results. Cool results are rare, but Nature, Science, Cell et al. are full of articles every month. So, most groups are overselling and misreporting things. Research fraud, p-value hacking and data manipulation are really common.
