Social Networks, microblogs and location
from memory by TonyAbouAssaleh
Participants: @tony_aa, @dirkahlers, @dajobe, @joshsh
- No technological limitations, many tools for detecting, encoding, and displaying location already exist
- How to integrate these tools into interfaces and micro-blogging service?
- How are people going to use them? Diverse needs and usage scenarios.
- Twitter imposes superficial limits -- unjustified
- Future of micro-blogging - how to overcome the size limit?
- encoding (short URLs, tags, abbreviations, location codes, etc)
- extreme case: gzip an encode the message
- encoding (short URLs, tags, abbreviations, location codes, etc)
- relax the limits
- Important that users have control over who sees their location information
- Important that users have control over the granularity of the location information
- point, block, neighbourood, city, region, etc.
- How to uniquely identify location?
- encode/decode by the client in a transparent way
- use natural language processing to disambiguate
Social Web and relations to Mobiliy/Context-awareness
(Notes from DKA)
Let’s not re-invent. Let’s re-use existing ideas of types of context.
Fading of information – value of context information varies over time – when you want to meet up with people and have a discussion you might want to know what room it’s in, but that information is only valuable at that time. Afterwards you only need to know that it was at WWW2009 in Madrid. Is this important?
More precise data kept for a longer time…
Do we need an expires-time for information? It’s important to keep things simple so maybe not.
What is proximity? Proximity refers to something to do with past behaviour of people. Social proximity can be divorced from actual location. Combined with distance-based location… Proximity is defined on underlying topology.
If you’re using a proximity-bases social network. Proximity doesn’t imply relationship. Physical proximity is only important if you’re already a friend of a person (if your social proximity is close)?
Use case – if you have social proximity then you happen to have physical proximity you might want to have a notification of that. Conversely you can infer a context from the physical proximity. Use cases for dating.
Changes of context are also interesting. [implicit] change of context can be used to change behaviour of applications or provide good user experience. A mobile phone sees where you are (home or work) and takes an action on your behalf.
Joined with calendar – you have information that the conference runs for so long, and you have an event after the conference at another venue… so you get some kind of smart notification. But E.g. Dopplr thinks I’m in Madrid but actually I’m in transit to London.
Granularity of groups of friends is an issue...
Events exposed through calendaring.
Context of “I’m in an airplane” or “I’m driving” or “I’m in a train” are important distinctions. “Nearest airport” is useful…
What do most humans care about? They want to publish a lot of detailed information about themselves to people that they know. Could they be triggered to publish more information on a change of context? “We noticed you’re in a pub right now – do you want to inform your nearby friend that you’re in this pub?” Even that might be too disturbing – tough to set up a double-blind system to inform on location/proximity. Also maybe this is too creepy.
Should it be illegal to discriminate based on your facebook profile when you’re hiring? Maybe this has to do with longevity of information…
Pre-camp Topic suggestions
Feel free to edit this section and append your own suggestion to the list or refine an already suggested topic!
Existing social networks still form closed communities. Could things be opened up?
Social data formats and mechanisms
[DISO Project http://diso-project.org/], XFN Microformat, hCard Microformat FOAF, SIOC, SKOS. OAuth, OpenID, FOAF+SSL. What do we need? SPARQLing social data and needed SPARQL extensions.
Identity and Privacy Technologies
OAuth, OpenID, TLS, SAML
Machine-readable tags make it easy to link users information. How can users privacy and/or anonymity be preserved?
Reading Grimmelmann: Who's the bigger privacy risk -- the social network provider or your friends? (tlr)
Is the availability of micro-payment payments a key enabler for new business solutions based on social networks?
Suggestion: consider a secure micropayment using a SPARUL INSERT over HTTP POST, and FOAF+SSL for authentication.
Capturing semantic data without bothering end users with it
I'm very interested in techniques which capture better information, especially links to URI's from other peopls systems, without bothering end users. My Mum won't enter a list of her alternate URIs... And I want it to be easy for me to implement.
Idea: one slide (optional) and two minutes time (sharp). Anything from announcements, controversial statements, project proposals, observations, etc. is welcome.
Suggested procedure: add your talk/topic, here or let Dom/TLR know at least a bit before the session (just to keep track how many people are interested).
- Michael on SPOT09 - call for demos and participation
- Michael on pushback, RDForms, pac etc. - what are the social implications and privacy concerns that come along with it?
- Harry Halpin on data-driven approach for social network models.
- Would like to see someone talk about OpenSocial
