Okay - so, I've spent ages searching in Google, and even went through a few specific searches at hotscripts etc., several php forums and this place ... nothing (not of use anyway).
i want to be able to take a block of text (page/file/doc) and pull it apart to find the "distance" between specific terms (find the proximity/raltional distance etc.).
I woudl have thought there'd be at least a few such thigns around - but I'm not finding them. So - it may be harder than I thought. I understand it may be a somewhat "hungry" endevour - as it's likely to be fairly intensive on large documents - but surely it is possible?
Infact - whilst looking around - the majority of references that I find (apart from lamo-repeat SEO sites) seems to suggest advanced linguistic studies, strange/advanced packages to install onto a server etc.
Am I to assume that "proximity" is infact a highly complex issue, and will require serious resources and an awful lot of development? (Honestly - in my mind it seems somewhat moderate - so I'm wondering exactly what it is I'm missing (Note: Simple in a relative sense ... I would compare it to easy (density/count) through to difficult(word stemming/base/thesaurusing)).
So - references/suggestions/ideas/thoughts???
