Also, feel free to put comments into the text and let me know if you want to discuss anything in person.

    The amount of data generated by people doubles roughly every 1.5 years. The plummeting of costs of gathering, storing, and indexing data is having a tremendous impact on the expectations of individuals as they create and share information about themselves and about their relationships with others, both in a C2W context (consumer-to-world, e.g., Twitter) and a C2C context (e.g., Facebook). What are the new data sources, how can they be used to create value for individuals, business, and ultimately society?

    Implicit Data
    No user generated data. Find already existing data and turn that into an explicit product.
    Learn from past behavior.
    An engineering challenge
    Crawling of data,
    ...
    Examples: Google, RottenTomatoes, rapLeaf.
    Explicit Data
    User willingly chooses to directly share data
    Written
    specifically says what he/she thinks/wants.
    e.g. Written
    recommendations
    A marketing challenge.
    Not necessarily a technology challenge. Only need to figure out how to get the mechanics right

    Depends on your team:
    If your team is made up of brilliant engineers/algorithmicists--> Use implicit collection/analysis of data.
    Mostly creative people,Business/marketing culture, not many
    Marry the two approaches

    Final Project Presentation: HappyMap Group- (http://sites.google.com/site/stanfordsocial/)
    Real-time, location based, sentiment analysis of social data. (Making something useful from implicit data at virtually no cost)
    - Some findings:
    - West coast tends to be more happy than the East coast
    - Lunch time is when people seem to be most happy
    - As number of tweets goes up, amount of happiness decreases
    - Uses sentiment analysis to determine "happiness"

    Implicit Vs. Explicit Data
    Auren Hoffman (founder and CEO of Rapleaf), started off his talk like this: "Raise your hand if you use Yelp". Then, he asked people to describe to him what Yelp was all about. The first two answers included the words "community" and "reviews". Hoffman pointed out that these words describe an explicit data set, because users are engaged with the website and they actively interact and change the information that you can find in Yelp.

    Liquor licence(Can serve only wine? Maybe only mixed drinks?)
    Does the owner of this restaurant own other restaurants (They usually do)
    Fundamental Problem:How to matchProblem:Matching data from different sources (How
    Once we have the data, how
    do Iwe know it'swhen people are talking about the same restaurant?)thing?
    Phone Number, address(harder to do match)
    Good key on people: E-Mail address.
    ...
    Each website has unique url.
    Bloomberg: Stock ticker symbols.
    - Conclusion
    When thinking about a product - try to frame it as an explicit site or an implicit site
    Perhaps there exists an explicit search engine (i.e. Facebook maybe?) that might be a Google killer
    Perhaps there exists an implicit restaurant review site that might be a Yelp killer
    These things might exist - but no one has been able to do them well yet

    A piece of advice:
    You never know what ideas will work, what won't.
    ...
    Bloomberg is another company that Hoffman talked about on Tuesday that uses implicit data. He also mentioned how implicit data is often related with engineering and technology and how explicit data has more to do with people, socializing and marketing. If you follow this link (http://about.bloomberg.com/thinktechnologysolutions/) you can see how Bloomberg advertises its image as innovative, and boasts about its use of technology. Specifically, "Think Fast" refers to implicit data gathering by talking about the real time information they get an about their automatic system to gather this data. I encourage you all to read more about Bloomberg so you can reflect on last Tuesday's class.
    Finally, check out ( http://www.rapleaf.com/ ) so that you can understand in more depth how Auren Hoffman uses data analysis in his day to day life and how companies like this are catalysts for the Social Data Revolution.
    Rapleaf History
    Originally were an explicit site for people to rate other people
    Original goal: "By showing people how good they are and incentivizing people to be good, make everyone in the world good"
    Turns out, "Good" is hard to evaluate in different contexts.(e.g. Bill Clinton may be considered a good president, perhaps not a really great husband..)
    Eventually, became a data company that focuses on helping companies market their products to the right segment of consumers
