Hi all,

sorry for this messy post - I forgot to subscribe to the list so I can't directly reply to your responses.

some or which are not very large so you might be able to use them.

Is the raw data available? Can I compute the clickstream myself?

Erik:

> This is actually how our production search ranking is built for around the
top 20 sites by search volume that we host. Simple wikipedia isn't one of
those we currently use machine ranking for though.

Awesome! Is there more info available somewhere? Algorithms used etc. maybe even source code?

> Because of that we do have the data you need, but the problem will be that the actual search
queries are considered PII (Personally Identifiable Information) and not
something I can release publicly. It may be possible to release aggregated
data sets that don't include the actual search terms, but at that point I
don't think the data will be useful to you anymore.

I think I'm fine with query-document pairs. Isn't that sufficiently aggregated to not be considered PII?

Thank you!

Georg

Hi list,

as part of a lecture on Information Retrieval I am giving we work a lot with Simple Wikipedia articles. It's a great data set because it's comprehensive and not domain specific so when building search on top of it humans can easily judge result quality, and it's still small enough to be handled by a regular computer.

This year I want to cover the topic of Machine Learning for search. The idea is to look at result clicks from an internal search search engine, feed that into the Machine Learning and adjust search accordingly so that the top-clicked results actually rank best. We will be using Solr LTR for this purpose.

I would love to base this on Simple Wikipedia data since it would fit well into the rest of the lecture. Unfortunately, I could not find that data. The closest I came is https://meta.wikimedia.org/wiki/Research:Wikipedia_clickstream but this covers neither Simple Wikipedia nor does it specify internal search queries.

Did I miss something? Is this data available somewhere? Can I produce it myself from raw data? Ideally I would need (query-document) pairs with the number of occurrences.

Thank you!
Georg
