Big Data it’s

not about the

How Big is Big Data?

The (forgotten) Humanitarian Crisis in 2013

Yemen = 10.5 m

Chad = 1.8 m

Afghanistan = 5.7 m

DRC = 2.6 m

Somalia = 3.8 m

CAR = 4.6 m

Big Data needs to be culturally sensitive

What happens

with

Big Data?

Big Data + Context + Action

= Information

Information saves lives

5th International Conference of Crisis MappersPanel I—What is so Big about Big Data?

(Reference..)

1. What is ‘Big Data’ about—and not about?

① Big Data as data == “traces of human actions picked up by digital devices” (Letouzé, Meier and Vinck)

1. “Digital breadcrumbs” (Sandy Pentland)2. Open web data (social media, online news..)3. Sensing (satellite, meters..)

② Big Data as data is not ‘about’ size—it’s a primarily qualitative shift

③ Big Data is “not about the data” (Gary King)

1. What is Big Data about—and not about?

Movement of an individual in Rwanda over 4 years (Source J. Blumenstock)

• Big Data as data doesn’t have to be big to be different• Big Data as data is about very many very small data

produced by / about connected individuals (big data is small data—it can also be slow data)

• Big Data takes intent and capacities

2. How will Big Data grow & age?

Stock of world data, circa 2020?Stock of world data, circa 1980 (assume)

2. How will Big Data grow & age?

1 10 1000 10000

50 years

90 days

Unknown data

① Descriptive analysis (e.g. maps)② Predictive analysis (proxying vs. forecasting)③ Diagnostics (causal inference)

3. How has / may it be used for humanitarian assistance purposes?

Source: Letouzé and Prydz, 2013

Pattern recognition + anomaly detection: Violent event in ACLED data vs. cellphone call volume in Ivory Coast

3. How has / may it be used for humanitarian assistance purposes?

NationalStatistical

Institutes carryout surveys

Telefonica teamused their data to‘predict’ SELs fromCell Phone Usage

Predict the present(SELs for non-

surveyed regions) and monitor the

future (trackchanges over time)

Survey from “a major city in Latin

America”

Example: “Prediction of Socio-Economic Levels Using Cell-Phone Records” (Telefonica research, 2011)

i. Main risks are① Creation of a ‘new’ digital divide

=>Recentralization of decision-making, reversing recent trends/efforts

② Dehumanization / de-democratization of decision-making (cf drones, killer-robots)

③ Confidentiality / security: e.g. CDRs de-anonymization and identification

4. What are the traps and priorities ahead?

ii. Main challenges/questions are① Political: Engaging with & empowering at-risk / affected

people and communities for community resilience, feedback loops, agile response..(urgency vs. sustainability?)

② Legal-institutional: Devising principles and frameworks for ‘responsible’ data sharing and analysis (D4D team)

③ Theoretical-methodological: further research / progress to take place on

1. Sample bias correction 2. Privacy: erasable future, noise in data3. Models of human response to emergencies 4. Causal inference

4. What are the traps and priorities ahead?

All data collectedall data shared

Extreme societal considerations / Open Data

society

All data collected,No data shared

Extreme commercial considerations / surveillance

No data collected,No data shared

Extreme individual consideration / Full privacy
