Karl Wettin commented on LUCENE-836:
------------------------------------
Regarding data and user queries, I have a 150 000 document corpus with 4 000
000 queries that I might be able to convince the owners to release. It is great
data, but a bit politically incorrect (torrents).
There is some simple Wikipedia harvesting in LUCENE-826, and I'm in the middle
of rewriting it to a more general Wikipedia library for text mining purposes.
Perhaps you have some ideas you want to put in there? I plan something like
this:
public class WikipediaCorpus {
Map<String, String> wikipediaDomainPrefixByLanguageISO
Map<URL, WikipediaArticle> harvestedArticle
public WikipediaArticle getArticle(String languageISO, String title) {
..
}
}
public class WikipediaArticle {
WikipediaArticle(URL url) {
..
}
String languageISO;
String title;
String[] contentParagraphs
Date[] modified;
Map<String, String> articleInOtherLanguagesByLanguageISO
}

> Key: LUCENE-836
> URL: https://issues.apache.org/jira/browse/LUCENE-836
> Project: Lucene - Java
> Issue Type: New Feature
> Components: Other
> Reporter: Grant Ingersoll
> Priority: Minor
>
> Would be great if the benchmark contrib had a way of providing
> precision/recall benchmark information ala TREC. I don't know what the
> copyright issues are for the TREC queries/data (I think the queries are
> available, but not sure about the data), so not sure if the is even feasible,
> but I could imagine we could at least incorporate support for it for those
> who have access to the data. It has been a long time since I have
> participated in TREC, so perhaps someone more familiar w/ the latest can fill
> in the blanks here.
> Another option is to ask for volunteers to create queries and make judgments
> for the Reuters data, but that is a bit more complex and probably not
> necessary. Even so, an Apache licensed set of benchmarks may be useful for
> the community as a whole. Hmmm....
> Wikipedia might be another option instead of Reuters to setup as a download
> for benchmarking, as it is quite large and I believe the licensing terms are
> quite amenable. Having a larger collection would be good for stressing
> Lucene more and would give many users a demonstration of how Lucene handles
> large collections.
> At any rate, this kind of information could be useful for people looking at
> different indexing schemes, formats, payloads and different query strategies.
