I just found that little note and learned that our German HQ is interested in a story about the Truth Teller App in combination with the coverage of the State of the Union.

I thought our FP and other political writers can check how good the Truth Teller App really is and compete in the truthfinding live-blogging on Dailykos and challenge the results the Truth Teller App provides.  

What is the Truith Teller App, you ask?

Washington Post Truth Teller app aims to fact check politicians in real time.

"We feed a video into our Truth Teller, it extracts the audio, it turns that audio into a transcript, then it takes that text, runs an algorithm and matches claims in that text to our database of facts and then returns back to the user whether this is true or false," says Cory Haik, the Washington Post's executive producer for digital news.
What the Washington Post had in mind is somewhat something like a lie detector service in real-time for its readers or viewers, said Cory Haik here:
Our solution is Truth Teller, which aims to fact check speeches in as close to real time as possible. Truth Teller is a prototype of a news application built by the Post with funding from Knight Foundation's Prototype Fund. The prototype, built in three months, is a big step toward real-time fact checking....

...We are effectively taking in video, converting the audio to text, matching that text to our database, and then displaying, in real time, what’s true and what’s false. The key to the project’s success is building an authoritative database - our goal is to identify falsehoods, not create more of them.

Technical Details:

We are transcribing videos using Microsoft Audio Video indexing service (MAVIS) technology. MAVIS is a Windows Azure application which uses Deep Neural Net (DNN) based speech recognition technology to convert audio signals into words. Using this service, we are extracting audio from videos and saving the information in our Lucene search index as a transcript. We are then looking for the facts in the transcription. Finding distinct phrases to match is difficult. Instead, we are focusing on patterns.

We are using approximate string matching, or a fuzzy string searching algorithm. We are implemented a modified version Rabin-Karp using Levenshtein distance algorithm. This will be modified to recognize paraphrasing and negative connotations in the future.

Now the question is how good is the WP database of facts ... may be the NY Times has the better database ... /ducking

If we just could use the Truth Teller App right now, live, in the John Brennan Hearing and see how much he tells the truth or not, that would be too good to be true, wouldn't it?

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
