      Friends,

      I'm wondering if anyone knows of a source of info that rates or provides some kind of feedback on different entity extraction, vocab management, automated tagging tools, etc.  A source that compares apps would be great.  Does such info exist somewhere?  If so, kindly let me know.  Feel free to respond privately if necessary.  Thanks a lot.

      Ari

        Hi Avi,

        I saw your synonym expansion comments. I agree, there are many ways and they are all valid. In my mind which one you actually pick depends on three things: Your audience, your content and your synonyms. Example: If you support a search on a customer facing website I'd compose a synonym dictionary that anticipates audience questions and is targeted to the content. You may end up with terms that are by no means synonyms in the strict sense of the word but provide meaningful expansions of the query. Then I would execute and automatically expand the query, highlight the terms and synonyms in the result and allow the user to opt out. In other scenarios, e.g. dealing with a targeted enterprise application and specialized users I would execute the query with the search term (and expansion based on standard lemmatization), display the search result and the synonyms or taxonomy to select from to refine the query.

        Regards,

        Karin

        I'm doing s ome research on this now, and I don't see much that's
        really useful, mainly research projects trying to expand recall,
        which is not a good idea for enterprise search.

        Functionally, search synonyms should work like a controlled
        thesaurus, because in most cases, you don't want to add a deprecated
        word to a search. Though sometimes that's useful, in a transition
        period.

        There's not much User Experience research I've found yet, and
        synonyms can really shake people's confidence in search engines.I
        know of several approaches, and there may be more

        1) Show additional search terms with check boxes in the search results page.

        2) Show additional search terms as links, with the prompt "You might
        also want:" (or something similar)

        3) Expand the query and show the expanded words in the search box

        4) Expand the query invisibly (I don't like this one, but lots of
        engines do it)

        For the third and fourth app roaches, bolding the match terms in
        context will help the users see why certain documents match the
        query. I think it might be nice, though processor-intensive , to give
        extra weight to the user-entered text, so they show up in the top
        results.

        All this isn't even getting into the question of multiple word
        queries and how hard it is to program something that will understand
        the changes in meaning in context.

        Hope this helps get you started!
