Week - 6 Pandora

- Pandora played 'Faith is the key' by Alvin Slaughter, i like it. I decided to add a little variety to my tastes by creating an central african gospel station. Unfortunately, Pandora's inventory was not that very large.

Week - 6 Pandora

- By now Pandora somehow figures out that I like Donnie McClurkin too much, and proposes me one of his hit most of the time I log in. Today I got Victory Chant by Donnie McClurkin (from my McClurkin station). Next ‘Yes Lord’ by Andre Crouch was played, this name sounds familiar to me but I don’t remember hearing one of his songs. I was curious to hear this song till the end. The song had an average raking according my taste, I flagged it as ‘I liked it’. Next i got 'Make me over' by Tonex, it's an artist that i don't really like much, 'i didn't like'.

- 'I need Thee every hour' by Don Moen was played, from one of my favorite album 'Thank you lord'. Next 'Breath' by John Tesh, a song that i've been look for but i didn't know who sang it, i got it !!!

The implementation of knowledge-based recommender system

The mainstream of recommender systems rely on collaborative or content-based filtering. This paper proposes a knowledge -based recommender system that interacts with the user and matches his/her requirements based on knowledge of the product domain using an inference engine (deduction based on rules). The knowledge base of the product and inference engine is implemented by JESS and java servlet. This approach requires a domain expert to model the object to macth with user requirements. After finding candidate products, cosine is used to measure similarity between the requirements and the products' features. The paper presents a sample implementation of a cellular phone recommender that uses phone model.

Week 5 - Pandora

- Today my Cece Winans station played ‘Jesus, You are beautiful’ by Cece Winams, an album that a friend let me borrow one time which I liked. Next I got Worship medley from Dr. Bonnie Hunter, I didn’t like it very much. But from this station, Pandora was getting a little closer to what I like. ‘You are loved’ Cece Winans was played next, it was my first time to hear to song but I liked it.

- ‘The heart of the matter’ by India Arie was played, a genre that I didn’t like to be played on this station. I asked Pandora why the song was played; it replied that this song matches my profile since it is a new style of R&B with strong vocal. I don’t think that India Arie is in the category than Cece Winans or Yolanda Adams.

Recommender systems recommend suggestions from data coming from s single organization database. Thus, they improve their accuracy with data availability and increased user's interactions. Systems that don't have data can't accurately predict. To solve the cold start problem, different recommender systems can share their knowledge in order to better the recommendations.

Week 4 - Pandora

- Now it's playing 'The awsome God' by Kevin Vasser, and it's one of my favorite. I reached my limit of song/per hour per station. Pandora suggested me to create another station if i wanted to continue listening to more music.
- I created a new station with Cece Winams as my favorite artist. First the station played 'All that i need' by Cece winams. Next it palyed 'All of my life' by Trin-I-Tee 5:7. It didn't like this song.
- Next Pandora played 'Fragile Heart' by Yollanda Adams, i really like it. By the way , i was lookig for this song on the net.

Week 4-Pandora

- Today Pandora played from my PSALM station "I'll be" by Little Milton; it's way off to my tastes. Next it played 'No one special' by the Robert Cray band, this one is alo off.
- I asked 'Why this song was playing' , pandora answered that based on what i told them so far. That the song features new R&B styling, a subtle vocal, mild rythmic, major key tonality and electric guitar. It is a little bit close to what i like but not this kind of music.
- Midnight to Day (by Tommy Castro) was played, but it's not even close to what i like. Curiously, Pandora starts playing 80's rythmic and vocal type music. (not me !). 'Magnificient Sanctuary Band' by Susan Tedeschi was next played, i didn't like 'cause it's not my kind. Next 'come around' by Needle was playing, it was clear to me that Pandora don't understand my taste for this station.

- I decided to to change station. I went back to my Donnie McClurkin station. Pandora played "The Potter's House" by Tramaine Hawkins, i sonehow liked it (half and half satisfaction)
- 'I will sing' by Donnie McClurkin was played and i like it.

Week 3 - Pandora

- I created a new station called "Psalm". I didn't like the first song (Good news by Michelle). I didn't like the next song "His precious Love" by Otis Clay.

- Next i got "Midnight train to Georgia" by Joan Osborne (what!!!!!!!!!). way off!
- Pandora starts returning all the artists that i previously turned down but with different song.

- As turned down so many songs, Pandora warned me that i exceeded the number of songs that i'm allowed to hear per hour

Week 3 - Pandora

- Today Pandora played Caribean Medley (Donnie McClurkin). Next I've delivered (by Georgia Mass Choir), i didn't like it too much
- I need Thee (by Don Moen) was played, i like it. You know me more (By Hillsong). Curiusly Pandora played some kind of music that i like.

Recommender systems use a database about user preferences to predict additional topic or products. In order to achieve this, conventional recommender systems rely on user x item informations and ignoring other factors that influence user preferences. By including temporal data, recommender system will efficiently make recommendation.
