And the context length limit prevents that relation from extending to more then a few articles, if that's your method.
i.e. Your method doesn't actually produce a meaningful score that can be ranked in some linear order with the 1200 other articles.
At most it would make sense to rank a discrete score in relation to the few other articles it remembers.
Anything beyond that should be placed in 'score ranges' from 5 to 7 for example, not given a discrete score.
