Correction: it was Ben Gimpert who said at the Strata 2012 Conference that what makes "big data" big is not its scale or (un)structure, but rather its high dimensionality. But I'm sure Mark Madsen would concur. :-)
@Nicole -- I'm saying that some people, no matter how much advice you give, no matter how many warnings you put up, are going to be careless and foolish. Right now we're sort of in the early stages of the affordable automobile as far as regulation and best practices go, so it's not surprising.
I'm sort of thinking back to what Daniel said and I think privacy is sort of a road-safety issue. I mean, you can repeat yourself until you're blue in the face but some kids are still gonna play in traffic.
Nicole, you probably have been using faceted search already -- it's on LinkedIn as well as the majority of online retail sites. If you're really curious, check out this book: http://www.amazon.com/Synthesis-Lectures-Information-Concepts-Retrieval/dp/1598299999
Nicole, personalized search is an interesting topic. At LinkedIn, all search is personalized because your network is a key aspect of what makes a search result relevant. For the general web, I'm not always convinced the personalization is essential. An alternate approach is to give the user more control of the search experience, e.g., through faceted search. But it's great that researchers and practioners continue to explore lots of ways to improve the search experience.
Smkinoshita, privacy is a shared responsibility. For example, you as a user shouldn't publish something that you weren't supposed to (e.g., covered under an NDA, something your best friend told you in confidence). It is the responsibility of social network services and others to make it transparent and straightforward how you are sharing.
Mary, I helped build one of those alternative enterprise search engines, so I certainly hope people keep pushing the envelope in this space. Unfortunately, it's an uphill battle -- I'll confess it's more fun to work on consumer internet software than on enterprise software. So my respect goes out to those who persevere on the latter.
@Daniel -- as far as I'm concerned, if you post anything online it's public. I know you honour your LinkedIn privacy policies, but how much do you feel that privacy should be the responsibility of the user as opposed to the network?
Nicole, I have played a bit with Wolfram Alpha -- I blogged about it when I was a beta user. It's an interesting idea, but I'm waiting to see how it evolves. You can search for my blog posts about it at http://thenoisychannel.com/
Joanne, I'd urge that person to create a rich and complete profile that represents their current position, past career history, education, etc. Photos help too -- you can find more about this on our blog / help pages. Plus, more complete profiles are likely to push your LinkedIn page to the top of web search results, and that's often the first impression you'd like to make on a potential employer.
Kim, I agree that Hadoop's being open source has been key to its success. At LinkedIn we're big belivers in open source -- in fact, we won an award at last year's O'Reilly OSCON conference for being the biggest contributors to open source for big data.
Hi Daniel - what would you tell someone who is starting out in their career and is trying to establish themselves on LinkedIn for professional purposes? What would you caution them about, from the data perspective? What would you encourage them about on this topic? How will data usage and analysis change in the next 10 or 20 years that they're active in their career?
If someone asked me "Why did you tweet that?" I would answer "Because in context, I had previous tweeted that I was trying a new place out, and I wanted people to know the experience was a good one so the restaurant would get additional business and I would get the chance to eat there again".
On the other hand, if an oversharer is in a position to hire people, they'd probably opt for others who overshare, or at least not ding them for it. I think it depends on the culture of the company as to what's acceptable sharing. They may see oversharing candidates as being more open and attuned to social media, which is a good thing.
@Nicole: I do, because I want people to be able to see what I do and how I interact if they are curious. If someone wanted to steal me away from my current company, I'd much rather it be into a culture that will fit.
@Nicole: Whether it's Twitter feeds, Facebook or any other site, professionals need to watch what they post everywhere/anywhere. Linking other accounts to LinkedIn is like leaving the front door open for others to openly snoop.
The context of LinkedIn is for the business environment. Therefore, users are more aware of posting professional content. Facebook is for personal use. Therefore, users feel free to share personal posts, which can be more damaging. Use of data therefore is more at risk for Facebook than LinkedIn.
Not really. The service of a social network is a 'free good' with a lot of benefit to me esp. Linkedin and I dont mind the network analyzing my data for its own benefit. Also if I am sharing an information on a 'social network', I never meant to hide it otherwise I wouldnt have shared it initially at a social place
The whole Amazon.reader debate is a double-stupid. It's stupid to think that there's any e-book buyer who doesn't know Amazon's URL, and it was stupider to let ICANN launch the whole free-form TLD initiative to start with.
Enterprises would like to move to cloud computing but are hesitant because they are concerned about providers’ ability to secure company data. Here are some tips that help to ensure that if breaches occur, the business is not left holding the bag.
Edmunds separates customers into segments based on the info it collects on its site and from partners, and uses that to push out custom content, said Brian Baron, director of business analytics for Edmunds.com, at Predictive Analytics Innovation Summit.
