Evonka is listening to music from an online music provider (such as Pandora or Jango). She builds a list of music preferences, including favorite songs. The music service then suggests additional songs she might enjoy. The music provider is an example of a cloud-computing application that uses a technology for collaborative filtering, which helps define the list of songs available to listeners. Which term describes this technology?

Crowdsourcing seems off for this one.

I think it's more like Software as a Service.

I feel like this is definitely about how the service learns from user preferences, so maybe it's crowdsourcing? But I’m not entirely confident.

I’m a bit confused. I thought grid computing was related to processing power, not music recommendations.

I think the answer is Software as a Service. It sounds familiar from a practice question we did about streaming services.

I remember studying collaborative filtering, but I'm not sure which term fits best here. It could be crowdsourcing, but that seems more about gathering input from many users.

I'm a little confused by the wording of this question. What exactly is "collaborative filtering" and how does it relate to the music service example? I'll need to review my notes to make sure I understand this concept before answering.

Okay, I've got this. Collaborative filtering is the technology that powers the recommendation engine in cloud-based music services. It analyzes user preferences and behaviors to suggest new content. I'm confident this is the right answer.

Hmm, I'm not totally sure about this one. I know it has something to do with how the music service suggests new songs, but I'm not familiar with the term "collaborative filtering." I'll have to think this through carefully.

This one seems pretty straightforward. I think the technology they're describing is collaborative filtering, which is used in recommendation systems like Pandora.

I'm going with B) Crowdsourcing. It just makes the most sense for a music service that learns from its users' preferences to suggest new songs. Grid computing? That's more for parallel processing, not music recommendations.

Ha! Bit-torrent? Really? That's for downloading pirated content, not music recommendations. This is clearly a case of collaborative filtering, so the answer has to be B) Crowdsourcing.

I agree, Bit-torrent is definitely not the right answer for this.

Hmm, I'm not so sure. I was thinking it might be D) Software as a Service since the music service is a cloud-based application. But I can see how crowdsourcing could work too.

I believe it's B) Crowdsourcing because the music service uses collaborative filtering to suggest songs based on what other listeners enjoy.

I agree with Melissa, the music provider is definitely a Software as a Service.
KE

I think the answer is B) Crowdsourcing. The music service is using the collective preferences of its users to recommend new songs, which is the essence of crowdsourcing.
DA

Yeah, it's all about using the collective input of users to make recommendations.
