Preservation and Forgetting: Friends or Foes?

Humans are very effective in remembering by abstraction, pattern exploitation, or contextualization. On the other hand, humans are also capable of forgetting irrelevant details, an important role in the human brain helping us to focus on relevant things instead of drowning in details by remembering everything. The research question that we address in this paper is: Can we learn from human remembering and forgetting in order to develop more advanced preservation technology? In particular, we aim at studying how a managed or controlled form of forgetting can play a role in digital preservation, including personal and organizational archives as well as collective memories. Our research goal is twofold: 1) to establish effective preservation for more concise and accessible digital memories, and 2) to enable the easier and wider adoption of preservation technology. The concept of managed forgetting is discussed in more detail in the research work of the European project ForgetIT, which investigates the proposed concept by mean of an integrated information and preservation management approach.

  • 4. Inspiration However we are facing – dramatic increase in content creation (e.g. digital photography) – information overload and changing professional + private lives – increasing storage costs for long-term storage (>10 years) – increasing use of mobile devices with restricted capacity – inadvertent forgetting in lack of systematic preservation And: Forgetting plays a crucial role for human remembering and life in general (focus, stress on important information, forgetting of details) 4 A Computer that forgets ? Intentionally ?? And in context of preservation??? So: “Shouldn’t there be something like forgetting in digital memories as well?  Forget IT

  • 6. Motivation 6  major progress in preservation technology  maturing Information extraction technology  storage as service (e.g. clouds) Opportunities increasing amount of digital content handled over decades  more or less systematic backup strategies used  non-paper practices for long-term perspective required Needs  large gap for adoption  high-up front cost  no established practices  lack of understanding of benefit  reluctance to invest Major Obstacles

Vision: Building a Bridge 7  major progress in preservation technology  maturing Information extraction technology  storage as service (e.g. clouds) Opportunities  increasing amount of digital content handled over decades  more or less systematic backup strategies used  non-paper practices for long-term perspective required Needs ForgetIT Enabling smooth transition to preservation Creating immediate benefit + reducing effort Opening alternatives to “keep it all” and “forgetting by accident” Easing interpretation in the long run taking inspiration from and complementing human memory  large gap for adoption  high-up front cost  no established practices  lack of understanding of benefit  reluctance to invest Major Obstacles
  • 8. Building the Bridge 8 Managed Forgetting Synergetic Preservation Contextualized Remembering • bringing back information into active use in a meaningful way • as opposed to the current “forgetting by accident” • inspired by human forgetting • couples information management and preservation management
  • 9. • High awareness of trip details • Showing of pictures • Sorting out redundant pictures • Sub-grouping and sorting Simple Example: Holidays 9 +20 Years+5-10 Years+1 Yearsafter trip +1 month • Trip to Paris with Friends • Thousands of picures • Life goes on • Pictures go out of focus • Creation of a small diverse subset for showing occasionally • Creation of summary page • Addition of context info • Further reduction of redundancy • Rest of pictures into archive February 2015 Paris Team: Me, Mary Christine, Tom • Changes in life (e.g. marriage) • Addition/ update of context information • Dealing with preservation issues girlfriendGirlfriend wife • Revisiting of Photo of trip photos • Re- integration into overall photo collection (link into context)
  • 10. Application: Personal Preservation Starting point: Tremendous growth of information in personal sphere Diversity and fast evolution of devices, platforms and formats Keeping info sustainably available: Only ad hoc solutions for mid-term, long- term solutions ForgetIT approach: Preservation solution for personal information space Based on concept of Semantic Desktop Consideration of social web content, multimedia content, other types of personal content, knowledge structures Additional short/mid-term benefit: de-cluttering information space by managed forgetting Consideration of multi-level infrastructures (e.g. mobile, PC, cloud) Dissemination/Exploitation: Personal Preservation as a service (e.g. to customers of a telco company) 10
  • 11. Application: Organizational Preservation Starting point: existing and popular CMS (TYPO3) Sophisticated workflows for content creation and publication But: Separation of publication and preservation/archival  Access to archived content is difficult and costly  obsolete and even outdated information stays online ForgetIT approach: Preservation as integral part (binary model  gradual managed forgetting) Bolder attitude towards removing content possible Automated support of cleaning up processes Support of many stages of archiving, e.g. offline but still in index, aggregates online/ content in archive, only aggregates kept, etc. Dissemination/Exploitation: Involvement of TYPO3 community, TYPO3 with preservation extension as open source project to TYPO3 community 11

  • 14. Managed Forgetting Inspired by central role of human forgetting Aim: – help in identifying and focus on relevant information – supporting preservation content selection Will replace inadvertent forgetting Managed forgetting ≠ automatic deletion Instead: range of forgetting options e.g. – resource condensation – change of indexing & ranking – reduction of redundancy Based on: Careful information value assessment Forgetting strategies via policies Forgetting options to integrate final manual checking before deletion Combination with multi-tier storage solution possible 14 Automatic Deletion? decreasing memory buoyancy Use of tiers
  • 15. Contextualized Remembering Aim: – bringing back information into active use in a meaningful way even if a lot of time has passed – aiming for semantic level of preservation Based on: taking into account relevant parts of context when moving to archive increasing contextualization of preserved content considering context evolution over time (evolution-aware contextualization) 15
