![]() We can then compute a reciprocal rank or just 1 / rank in the examples below Query If we search for “How far away is Mars?” and our result listing is the following, note how we know the rank of the correct answer. In question answering, everything else is presumed irrelevant. Such as in the two questions below: QueryĮach question here has one labeled, relevant answer. This occurs in applications such as question answering, where one result is labeled relevant. If MRR is close to 1, it means relevant results are close to the top of search results - what we want! Lower MRRs indicate poorer search quality, with the right answer farther down in the search results.Īs MRR really just cares about the ranking of the first relevant document, it’s usually used when we have ‘one relevant result’ to our query. Mean Reciprocal Rank or MRR measures how far down the ranking the first relevant document is. For this reason, I want to look at how Pandas can be used to rapidly compute one such statistic: Mean Reciprocal Rank. As you experiment, you’ll want to compute such a statistic over thousands of queries. © Twitter.If we’re building a search app, we often want to ask ‘How good is its relevance?’ As users will try millions of unique search queries, we can’t just try 2-3 searches, and get a gut feeling! We need to put a robust number on search quality.

Syrinx is free, but donations are accepted through the website. Syrinx 2.0 requires Mac OS X 10.5 (Leopard) and a Twitter account which is free. As with all of Syrinx's functions, keyboard bindings are set for all these new options, allowing you to navigate and interact with your timeline of tweets without ever leaving the keyboard. Other new features in Syrinx 2.0 include URL shortening, retweeting, tweet deletion and even more ways to customize the look of your timeline. All tweets after the bookmark are shown with a customizable background color to make new tweets easily recognizable. Rather than the tedium of marking each tweet read, the bookmark allows you to mark the last tweet you read, just like a bookmark in a book. The bookmark, the better way to track unread tweets introduced with Syrinx, can now be saved between launches, making it easier to keep track of your new tweets. Multiple search windows allows users to track multiple search terms and hash-tags with ease as they auto-update, accumulating new results in easy to follow timelines. Syrinx has always been able to search your personal timeline, but 2.0 introduces the ability to search all of Twitter. This same timeline efficiency has been applied to the Friends list, allowing you to locate and manage your contacts faster. Searching, scrolling and viewing conversations in Syrinx 2.0 is now instantaneous even after receiving thousands of tweets. The timeline for this new major release has been completely rewritten to make it faster and more lightweight than ever before. Syrinx is a full-featured native OS X application designed to make your tweeting easier than ever.
