Tool to tag content on the fly

[madeonmoon]

Hi all,

One of my sites is a Java/JSP site. I am wondering if there is a tool/plugin/library that I can use to generate and display tags for each of the pages on the fly. Say the site is in the business of making blue widgets and operate in NYC, the tagging plugin will automatically generate tags when rendering the About Us page: "widget, blue widget, widgets in NYC, NYC".

Thanks for any pointers!

So you want something that will parse the language on the page and figure out how to automatically tag them? That sounds like a tall order.

Or do you mean that you just want an interface where you can go through and add tags for each page which will them get displayed when the page renders? Do they need to be links that will list all other pages tagged with the same tags?

I would think your best solution would be something that integrates with whatever custom code you have running the Java/JSP site. Ideally, you would add the necessary tables to the same database that runs the site and then create something on the page edit form that would let you add tags. Unless you just want something like meta tags that don't link to pages, in which case it could just be a single field added to the table that holds the basic page data.

ergophobe, thanks a lot for your answer. Yes, I want something that will parse my pages on the fly before rendering and create a list of tags/a tag cloud before rendering. It does look like my best bet is to right (a lot) custom code ;)

The hard part is going to be to figure out what to tag. How do you plan to do that? Basically, it seems like you need some sort of indexing algorithm that will find the most important words on the page.

That's no small order. Even Google gets it wrong half the time in absence of other signals (keywords in incoming anchor text and so forth).
