Where I come from?

2

Short Background

• The name of the group I come from is • We started to work on Digital Preservation from

(PReservation Organizations using Tools in AGent Environments, 2007-2010)

• Since then, we have been involved in more DP projects– PRESERVA (2010-2013)

• Comparative approaches to the implementation of intelligent agents in digital preservation from a perspective of the automation of social networks

– MIDPOINT (2012-2015)• New approaches to digital preservation with better cost

management to ensure sustainability

– DURAFILE (2013-2015)• Innovative Digital Preservation using Social Search in Agent

Environments

Why I decided to come here?

• Buckets (Michael L. Nelson)

– The very first evidence of object-centric paradigm. Buckets were designed to imbue information objects with certain responsibilities, such as the display, dissemination, protection, and maintenance of their contents

• At JCDL 2013 we met and we though it would be the best place where I could do a profitable stay

Statement of thesis

• My thesis will study what self-preservation behaviors need the self-preserving digital objects (SPDO), based in computation intelligence (CI), and related methods of cost management under their own budget, powered by a social network as an environment that enables their behavior under the policy that “preservation is to share”.

• In this concept, digital objects become active actors in their own LTDP, which has a DP budget devoted to funding the replication of the objects and other operations such as format migration or moving through a social network of users; in all, a controlled environment where they will “live”.

Roadmap of the thesis

8

Research questions

• (A1) Behavior model– Evolutionary Computation techniques that back the

preservation of SPDOs– Swarm Intelligence techniques that back the preservation of

SPDOs

• (A2) SPDO architecture from the agents– Social skills that determine how they interact with each other– How they must manage their budget (devoted to funding the

replication of files and other operations such as format migration or copying themselves through the social network of users)

– How they will manage their copies, that are distributed in the social network

9

Research questions

• (A3) Social environment

– How the social network must technically be

– What are the topologies of social networks that back better the digital objects and how to promote these topologies

– The definition of compensation mechanisms for users to promote user engagement

Research goals

• Work in the three confluent areas explained before (A1, A2 and A3) separately. The work is being done on a simulated environment where results will be obtained, analyzed and made partial publication of these results in conferences and journals

• A state of the art from the articles published on the topic

• Finally a prototype will be implemented in a real environment based on the research that has been done

Possible collaboration opportunities

• Self-preservation behaviors based on Computational Intelligence (CI), focused on Web archiving– save all associated resources (images, style sheets,

etc.) to preserve look

• Improve TiM thinking on real live limitations

• How should be implemented in real life / show this behaviors to final users in order to engage them Gamification
