Participants' satisfaction within open systems
Advisors: Patrick Valduriez and Philippe Lamarre
Key words : open systems, heterogeneity, autonomy, incentive, satisfaction
The general focus of the research are open systems with autonomous participants that behave according to their own goals. Recent internetcollaborative applications for sharing data, knowledge, opinions, experiences fall within the scope of interesting applications of this problem. Virtual communities [AP07,FHM05], collaborative medical research [Sta+08], social networks [Der07] are other applicative frameworks which refer to the same problem : in every case, one main goal of the system is to satisfy the participants despite (or thanks to) their autonomiy and the heterogeneity that follows.
Recent interesting results on query allocation within such context [QLCP07, QLCP07a, QLCP07b, QLCP08] have been shown. Their principle is simple : the participants express their wishes, their intentions with respect to their involvment within the system ; then it is possible to determine to which extent their whishes are satisfied and tend towards some kind of equity by promoting the less satisfied participants (if possible). This approach has very interesting advantages in this context :
it enables a high genericity : The system only considers the participants' intentions without having to deal with the details of the application. it preserves a high degree of autonomy for the participants. Indeed, they are responsible for computing and expressing their own intentions. Thus they can consider the criterias they want and aggregate them according to their own strtagy.
The theoretical bases of the approach combine elements of game theory, micro-economy and sociology.
A main goal of the thesis is to combine the satisfaction based approach with other important notions in open systems, like trust and reputation. Thus this thesis should focus on (i) generalising the query allocation model defined in [QLCP08] to more complex systems (ii) studying the contribution of the notion of satisfaction and its interaction with notions of trust and reputation. (iii) contextualizing the above notions.
The baseline idea is that these notions are intimately linked but they are not monolythic. One can be very satisfied by the results obtained through some participant which is trusted for a given domain, whereas it can be considered very insatisfactory in another domain or for some other type of work.
Within the APPA project framework (Atlas P2P architecture) [AMP+06], the aim is to validate the approach by developping a virtual community. The supporting technologies would be a DHT like P2P network (like OpenChrod or Pastry) with replication techniques [APV07] and standard Web protocols for communication (XML, HTTP, SOAP). We wish to developp an application for natural environment domain, in order to favor the exchanges between actors in the management of environmental projects. First, several realistic scenarii involving different types of participants like oceanographers, geologists, biologists, climatologists sociologists, economists wanting to share information, will be studied. They will be used to validate the future architecture. Second, a prototype will be developped in order to validate the proposed solutions.
