The 2009 MusicTech Summit has wrapped up and the blogosphere has some recaps for those who did not attend.

GigaOm's wrap-up was heavy on the topic of the semantic web. "According to a morning panel, sentiment analysis - the form of natural language processing that assigns positive or negative attributes to a statement - can prove useful to a record label, music marketer or consumer brand looking to gauge listeners' interest or feelings about an artist. A late-afternoon panel suggested that traditional recommendation engines, which have typically been built by editorial experts or used collaborative filtering, can be improved by harvesting relevant data from a massive river of unstructured information, helping to prevent the engines from being gamed by hackers or misled by feedback loop."

The Washington Post's Faster Forward blog has an overview and an interesting tidbit from a panel discussion about connecting fans with artists: "This isn't without risks: Jeremy Welt, of Warner Bros. records, said some artists don't react well to criticism: "I've seen bands melt down before going onstage just because they're looking at the message board." It's also possible to geek out a little too far when seeking feedback -- one panelist cited the example of a band that suggested onstage that its fans use a particular hashtag to talk about the show on Twitter."

Zed Equals Zee's MusicTech roundup highlighted the partnership with Echo Nest and Spotify and named the "Monetization: Idealism in Practice" as the most lively. "It was worth going to the panel just to see the Electronic Frontier Foundation (in the person of Fred Von Lohmann, one of their senior staff attorneys) on the same side as the major record labels (Choruss was started by Warner and is backed by several other majors). However, this is still a pretty contentious proposal, especially since the colleges are kind of paying protection money ('you promise not to sue us, right?'), because it's not clear how the indies or unsigned musicians will be represented, and because it seems incompatible with other business models."

The recap at Got Game has positive words about a panel on music recommendation. "The panel included Machael Papish (MediaUnbound), Stephen White (Gracenote), Alex Loscos (BMAT), and James Miao (thesixtyone). This panel was interesting in that the panelists were not trying to advertise their products, they genuinely discussed the changes in the music recommendation product that each had in regards to the changing market. All stressed flexibilty with their services, and that simply releasing a music recommendation algorithm would lead to consumer anger in the force-fed nature of those programs."
