What are big research problems in Social Web technologies?

Just finished reading Dion Hichcliffe's piece over at ZDNet on emerging technologies for Social Web in 2010. I have been reading all these different predictions to see how it relates to our research agenda. Dion's piece is long, but several points resonated with what we have been doing:

First, he said that one problem we have is
"Poor integration between social media and location services. Again, while there’s already some location awareness in social networking services today, there’s a long way to go before it’s integrated meaningfully into the social experience to provide real utility."
I agree wholeheartedly. Not too long ago, I participated in a research project here at PARC called Magitti, which was an activity recommender that modeled your content interests, your schedule, your location, as well as the your personal history on the mobile device [1]. The integration of personalization and social features with location-aware services will be a significant trend in 2010, and there will be a lot of good research and products in this area.

Second, he said that people are having difficulties in
"coherently engaging in social activity across many channels. Tired of the day-long round-robin between your e-mail, SMS, Twitter, Facebook, and any other services you use to keep up with what’s going on? You’re not the only one. While aggregation services such as Friendfeed potentially cut down on the manual effort of using the social Web, it’s still not mainstream despite being a good example of what’s possible. Notably it’s often the big (and closed) social silos that are causing the problem."
Our group was an early adopter of FriendFeed, and realized that many of the issues relating to social annotation, commenting, and other interactions were due to the distributed nature of social media. It is hard to keep track of who said what, and the aggregate reactions to content. Our research group has some investments in this research problem, which relates to aggregation and the ability to browse and filter the feeds. We are about to publish a paper in CHI2010 about how to use faceted browsing techniques to partially solve this problem [2].

Finally, the most important point he made was the our need in
"Coping with and getting value from the expanding information volume of social media. We’re all learning how to deal with the firehose of information that flows out of social media on a minute-by-minute basis. Sometimes it’s hard to remember that this flow of transparent and open information is actually good and often useful and creates important conversations. But the simple fact is that much of it isn’t meant for non-stop, instantaneous consumption [emphasis added]; it simply isn’t practical. Rather, social media leaves behind artifacts and information that we can find and use later when we need them. But at the moment the process of sorting through, aggregating, and filtering the vast volume of information cascading through social media today remains a real and growing challenge. I also began to get the first real reports that this is happening in the enterprise last year as social media begins to grow there as well."

Here ASC group's investment in summarization, recommendation, and personalization, etc, hopefully will pay off. Our investments have been in understanding particularly how to apply these techniques in social media, with the added social contexts and new data mining techniques around social streams. Research-wise, we will be pushing on this last point the most, and I believe it is also the area we most likely can extract user value. We are about to publish a paper at CHI2010 on how to do recommendations on Twitter network [3].

I will blog about these research efforts soon.

This is incredibly interesting -- thank you for sharing your insights. I agree wholeheartedly about the comment on social media/location services integration, and look forward to developments on this.

There are some efforts that are starting to integrate social media and location, but platform companies like Facebook, Twitter, Google will have a big advantage, due to their integration capabilities. We'll have to see.
