1. Chain of Custody

• Record all your steps

Software: Hunchly https://www.hunch.ly/

Plain document

• Store original data in a secure area

• Create “digital fingerprints”: MD5 Hash

• Work only with a copy of the original data

Challenges

High data quality required for good

analysis results

Constantly increasing data quantity

Cleansing/Standardizing data

23

“Poor data quality” samples

Cleansing/Standardizing data

24

Why should data be cleansed:

Reliable analysis results are required

Saves time that otherwise would come

up during the analysis process

Reduces unwanted deviations &

variations

Identify entities (person, organization,

address)

Insights often lead to further findings

Cleansing/Standardizing data

25

Fast and flexible handling of large quantities of data

Flexible import for various data sources

Intuitive research

Analyses, calculations, statistics

Business Intelligence

Ad-hoc reporting

26

Solution

Combine different data formats

Fix data quality issues

Identify missing data

Better link analysis results

Application of different tools for standardized data cleansing

27

Solution

28

Solution

Develop automated queries

Benefits

Develop workflow for recurring

processes

Standardize processes (templates)

Benefits:

Time saving

Flexible

Maximize effectiveness

Team “compatibility”

Easy to learn

44

Analytics … yes … but structured:

Identify needed analytical steps

Develop „questions“ to data

What has prompted the need for the analysis?

What is the key question that needs to be answered?

„Create“ evidence out of data

What can you prove?

What do you want to prove?

Visualize your thinking!

Analyzing data

45

Analytical techniques

Chronologies and timelines (understand

timing and sequence of events)

Sorting (categorizing & hypothesis

generation)

Ranking, scoring, prioritizing (determine

which items are most important)

Network analysis – analyze relationships

between entities (people, organizations,

objects)

Analyzing data

46

Supporting tools:

Documenting processes in intranet/wiki

Select the right tool for each task

Train the users

Keep the users “busy”

Analyzing data

47

Query - an investigative question,

converted into database search

Analysis Sample: i2 IBM

48

How many organizations are known at

this address?

Analysis Sample: i2 IBM

Analysis Sample (InfoZoom)

Decoding (classification, i.e. phone data)
