Robert Muir commented on LUCENE-1532:
-------------------------------------
when you talk about hardcoding normalization, I really don't see where its
unfair or even 'hardcoding' to assume a zipfian distribution in any corpus of
text for incorporating the frequency weight....
I agree the specific corpus determines some of these properties but at the end
of the day they all tend to have the same general distribution curve even if
the specifics are different.
> File based spellcheck with doc frequencies supplied
> ---------------------------------------------------
>
> Key: LUCENE-1532
> URL: https://issues.apache.org/jira/browse/LUCENE-1532
> Project: Lucene - Java
> Issue Type: New Feature
> Components: contrib/spellchecker
> Reporter: David Bowen
> Priority: Minor
>
> The file-based spellchecker treats all words in the dictionary as equally
> valid, so it can suggest a very obscure word rather than a more common word
> which is equally close to the misspelled word that was entered. It would be
> very useful to have the option of supplying an integer with each word which
> indicates its commonness. I.e. the integer could be the document frequency
> in some index or set of indexes.
> I've implemented a modification to the spellcheck API to support this by
> defining a DocFrequencyInfo interface for obtaining the doc frequency of a
> word, and a class which implements the interface by looking up the frequency
> in an index. So Lucene users can provide alternative implementations of
> DocFrequencyInfo. I could submit this as a patch if there is interest.
> Alternatively, it might be better to just extend the spellcheck API to have a
> way to supply the frequencies when you create a PlainTextDictionary, but that
> would mean storing the frequencies somewhere when building the spellcheck
> index, and I'm not sure how best to do that.
