ForgetIT 1st Review Meeting, April 29-30, 2014 Kaiserslautern, Germany

ForgetIT Project GA600826, 1st Review Meeting, Kaiserslautern, April 2014

Realize & evaluate the ForgetIT principles for Personal Preservation

Leveraging effort for Personal Information Management (PIM) using

the Semantic Desktop approach and PoF-Framework

Objectives of WP

Why PIM & Semantic Desktop?

Allows to cover daily activities of users for• getting hold of the resources• deriving evidences for preservation value & memory buoyancy• providing further context for remembering

by providing benefits for PIM

for enabling preservation and reducing required effort


Focus of Year 1

• Identifying scenarios, requirements & use cases

• Deriving enabling features from the Semantic Desktop & extending the underlying ontology PIMO (Personal Information Model)

• Extending Semantic Desktop and first prototypes/mock-ups

• Preparations for evaluations in Year 2

PIMO PIMO

Personal Information Model (PIMO) in a nutshell

PIMO represent the user‘s mental model as vocabulary for applications

Scenarios & requirements for Personal Preservation (D9.1)• Input from all WPs & influenced from WP 2 survey• Main scenarios

- Trips- Events- Reminiscence- Hobbies & Noise (daily activities)- Preservation

Prototypes & Mock-ups (D9.2)

Extended Semantic Desktop Infrastructure• Embedding first ForgetIT results

Achievements in Year 1


Covers the travel scenario in WP9

~1500 real photos from travel and events• most prominently a Costa Rica

journey

Available as Stainer PIMO• incl. HowTo for installing

by everyone• on the ForgetIT testbed

Photos annotated by the persons who shot the photos

incl. preparation work (travel info, bookmarks)

Data Set for Personal Preservation: Stainer Data Set


Semantic Desktop used for PIM in daily work

at DFKI for over 2 years• “eat-your-own-dog-food” • PIMO concepts & resources (over

10.000) and access log

Provides insights and real data for

memory buoyancy, preservation

values, etc. (input to WP3)

Extended SemanticFileExplorer with PIMOCloud & PoF-framework

SemanticFileExplorer embeds

PIMO in Windows Explorer

PIMOCloud realizes PIMO-based

cloud storage service• Provides API• Access PIMO resources on

various devices

Interaction with PoF-Framework

enables synergetic preservation &

managed forgetting of user’s resources

on the computer (WP8,WP5)


Preservation embedded in File System

Preserving a file is embedded in

the MS Windows Explorer for easy

access

Restore from the archive

embedded in the

file system


Using Memory Buoyancy (MB) for realizing Forgetting

MB calculation based on evidences

from Semantic Desktop

For uncluttering the desktop from

unused files by removing them from

the file system

For uncluttering the PIMO by hiding

things assumed to be forgotten


PIMORE – PIMO-based Reminiscence

Prototype for personal photo

organization using the PIMO• for effortless preservation &

towards reminiscence

Leverage user’s efforts for photo

albums to get evidences for• context• relevance

Basis for discussion with WP2 for

scenarios & evaluation settings.

Role of the Semantic Desktop components

mobile PIMO server archive• Immediate relevant

material is available• Recency in model as well

as important concepts (hotness function)

• Only most recent versions of resources required

• Constant swapping/ refreshing (in WLAN) to keep recency is OK

• Quick availability of recent & work related material

• Broader range of resources: work relevant are available on immediate access (e.g., think of offline requirements); outdated ones are available on request

• Clutter of not-relevant stuff is gone, i.e., details can be removed from desktop

• “relieve the burden to see everything”

• All versions are available upon request

• However, over years, detailed material would be condensed, i.e., keep the deliverable but not the versions of the file, not necessary any more (e.g., after 1 year)

desktop• Provides access to all

material• Condense and compact to

get a sharper view• Old versions of files can be

deleted & moved to backup/archive

• Semantic associations allow to remember & access archived material

• Users are able to “pull on strings” to get the information back; like reconstructing a certain event by starting with the impressive building it was located.
