context competition

April 26, 2010

Not everyone ‘likes’ the implication foreseen for the Facebook Like button.  Adina Levin’s writes concisely about social context, its benefits, the activitystream standard and competitive forces in the market of context services.   The current paradigm for FB news feeds is to author once and send to all (from F8 a FB solution to this is to introduce Dashboards from different application or likes).  Whereas Adina holds up an activitystream vision for users context to be given the “‘capability to create more refined – and contexually relevant – posting choices and reading filters”.  She makes the case that the ‘like’ button holds to a different social context vision one where “Facebook is your one and only source of context”.

The opensourcers at FB point to their adoption of RDFa and the flexibility this provides, especially when connected to the FB API, including freer access to all openGrapth data types.  Adina makes a call for FB to adopt the Activitystreams standard and to complete on a level playing field with others wishing to specialize in offering such services.  How can you compete?, offer websites an activitystream based services where the users get a better context experience and then let those users spread the word.

filtering social news

April 23, 2010

What are the magic ingredients that brings the best information to us in a social context?  A couple of months ago I presented the whole story on the logic going on behind mepath.com.  This week the development team over at facebook partially presented their model.  The techcrunch blog has a great summary.

EdgeRank is the core metric formed and a news feed is a series of Objects prioritied by edgescore.  This can be summarised in the following equation:

The Sum of all Edges = Ue * We * De

where U is the affinity score between the user and Edge creator, W weight for each edge type, D time discount.

U – is real interesting as it is trying to decide how close you, the reader of the news stream is to author of the object.  Now, FB has a great starting point, they know there is a social connection between you and the author as only friend connections are brought back into a new feeds (OK, slightly more complicated as fan pages etc or app. data may feedback object not authored by a friends ie. like a RT of a non follower on Twitter).   By contrast mepath is given no starting relationship connection, it has to decide that itself and does so based on the lifestyle context of an individual over time.

W – applies a weight based on the type of edge e.g. comment, video post etc.  In effect saying the type of media authored can be biased up or down.  That is real interesting but how these weighting are decided is of even more interest?

D – time discounting.  Real time to later time.  Everyone one wants the latest but just in case we are not logged in 24/7 then we can review top news that ‘holds’ on to some friends post for longer, minimizing the chance you missed important news.  From my thinking on time filtering data, it is a deep and complex science all on its own.  The most important information an individual wants may well have happened in the past and well into the past.

While we can segment and split all we like, the simple objective remains, bring back the best information that is possible to have for the individual.  And increasing the will found and be achieved by understanding both the context it is initiated and understanding the context in which is was authored.

text, photo, video lifestlye mashup

April 14, 2009

The activity stream on mepath.com has expanded to include video.  Each sporty activity stream starts with photos, then video and then a list of blog posts, all are up-dated on 24 hour cycle.  The mashup of content types has made each sport stream more instantly identifiable and while you can go to flickr and youtube to view the same content having it all aggregated in one place provides a convenient way to discover information on a daily basis from the world of sport.

My current favorite streams are the skiing activity stream and the triathlon activity stream.

swimming technique

March 6, 2009

My swimming activity stream today brought a post on swimming technique .  What I really find beneficial about this information is that it is authored by a fellow swimmer and in this case a triathlete too.  He sets the background that us fellow master swimmers recognise and the post acts as a reminber on what to concentrate on next time we hit the pool.
