Challenges in Using
Lifetime Personal Information Stores

The 1 TB Life

1TB gives you 65+ years of:









100 email messages a day (5KB each)
100 web pages day (50KB each)
5 scanned pages a day (100KB each)
1 book every 10 days (1 MB each)
10 photos per day (400 KB JPEG each)
8 hours per day of sound - e.g. telephone,
voice annotations, and meeting recordings (8 Kb/s)
1 new music CD every 10 days (45 min each at 128 Kb/s)
It will take you 5 years to fill up your 80 GB drive
Want video? Buy more cheap drives (1 TB/year lets
you record 4 hours/day of 1.5 Mb/s video)
Everything goes in a database

You need all the features of a database
(Consistency, Indexing, Pivoting, Queries, Speed/scalability, Backup,
replication)


If you don’t use one, you will find yourself creating
one!

Memex
As We May Think, Vannevar Bush, 1945
“A memex is a device in which an individual stores all
his books, records, and communications, and which
is mechanized so that it may be consulted with
exceeding speed and flexibility”
 Full-text search, text & audio annotations, and
hyperlinks
I am data
Capture and encoding
I mean everything
Personal Search is not
Professional or Web search
System sees every entry & access
 Everything, not just a professional life
 Limited to SIS, not an infinite amount,
covers a profession & personal life

MyLifeBits
Professional user
Depth e.g.
information
item types
& coverage
Web as seen by search engines
Knowledge breadth e.g. Dewey classification
Why bother? ..some reasons

Technologist: “we can” an opportunity e.g. 1 TB disks
For all of us with new media: a need e.g. jpg. Mp3
Environmentalist: eliminates “atoms” (paper, CDs…)
For business--memory enhancement & faster search:
Let content analysis and data mining discover trends
and correlations in our lives…that even we don’t know.
Business: It costs more to delete than it costs to store
Preservationist: decays or disappears unless its saved
For the human pack rat: “I may need it some day.”
For posterity and nostalgia: “Maybe others will want it.”
Stories and ambience: basis for creating content
For the aging & failed memory: surrogate memory
Using my life bits:
beyond folders
#1: Folders
One item. One place.
It worked for 1000s of years.

 Don’t make me invent unique names
 Don’t make me file everything
 Or let me pick multiple folders

“multiple categorization not only improves
organization and retrieval times but also
matches more closely with the way users
naturally think about organizing their
information” – Quan et al (MIT’s Haystack)

collection dialog
Of course Aliases and Shortcuts can be used albeit painfully
to file by time and/or event, subject, location, type.
Using my life bits:
easily adding valuable content
#2: Text annotations
Making bits more valuable and retrievable.
“Its just bits until it is annotated”
Getting the user to tell a story is the
ultimate in media value




A story is a “layout” in time and space
Most valuable content (by selection, and by being well annotated)
Stories must include links to any media they use (for future navigation/search –
“transclusion”).

Using my life bits:
the value of time & time posts

Using my life bits:
Where, an essential attribute
#4: I remember where
Just essential.
Using my life bits:
pivoting on data to aid recall
#5: Relationships (links)
Using something near ‘it”, to find “it”.

Using my life bits:
never enough meta-data …

#6: more meta-data (properties)
I remember something about the content

Using my life bits:
classification of everything
#7: classification
Is any gain from non-automated classification
worth the cost and pain?
Is traditional classification required?
…at OCLC there was unanimous agreement
among faculty and participants that
“access to electronic resources
requires controlled vocabulary and
classification”

and Concepts for Next Generation Catalogers”, 17-19

Classification wish list

Download classifications rather than build them
Definitions & synonyms should help find what I want
Today it is too expensive to manually classify my
scanned paper. E.g. “right time” meta-data is critical!
Next year we hope “the system” can classify papers
and other documents e.g. bills
In 10 years we expect all documents to appear
electronically & classified with a little help from me
Using my life bits:

useful? or fool’s errand?

The Agenda for the Tbyte(s), Lifetime, PC:
The killer app after office and mail.searching
1.
2.
Guarantee that data will live forever! “dear appy” problem
Cheap, easy, and data-rich (e.g. time, place) capture:
GPS and time everywhere
Paper capture has to be as easy as discarding (scanner/shredder)
Personal meeting capture...perhaps by the room
E-book…e-magazines & journals need to have critical mass!
Telephony and audio capture with indexing (telephonic speech-to-text needed)
Media Center compatible for entertainment (photos, video, TV, radio)

Content analysis (critical for photo & video!); doable for text.
Information control: privacy, security, expunge/deniability,…
Having to be schizophrenic or have a lobotomy when leaving a “life” or
being a part of some other person’s life recording
One dbase for everything (articles, books, conversations, ... financial
transactions) …vs. long-term use of hierarchical files. Is dbase intuitive?
Annotations/meta-information add every-increasing value at high cost!
Easy annotation for aiding search and it becomes the content
Other “killer apps”: Alzheimer, immortality, surrogate memory?
GUI’s to improve use (e.g. time to learn, use, aid in retention)
