Methodology

Architectural overview

Data processing • 20 years data analyzed

• 12 years have complete titles • 8 years do not have complete titles • 6189 files analysed • 314 meta files per year ( Avg)

• 12 years => 3754 issues • Word counting, formating files to/from XML, D3 and Jigsaw

• Hadoop processing was impressive

Idea generation • What happened in the 19th century?

• Find interesting stories

• Where were events happening? • Overview of mentioned locations

• What were the most common topics? • Overview of frequent words • Categorization of words

• Who was mentioned? • Entity recognition of names

Visualization (overview)

Visualization (overview)

Visual Exploration with Jigsaw • Jigsaw already has good functions and visualizations!

Visualisations (Beyond Jigsaw) • More numerical analysis

• User selected dimensions and exploration

• Dynamic visualization

• topics, locations, entities

• Pattern analysis

Interactive visualisation

Dynamic exploration

Insights • Industrial revolution in Dundee

• Frequency analysis, cluster overview, positive sentiments

• LATEST MOVEMENTS OF DUNDEE JUTE FLEET • Entity relations, bigram analysis

• Calcutta, Indian subcontinent? • Location-commercial significance

• Baxter Brothers was the world's largest linen manufacturer (1840-1890) • Family names-organization

Conclusions • A really steep learning curve • Big data is BIG • Distributed computing is important • Data wants to tell interesting stories (we just need to interact) • Visualisation is powerful • Jigsaw is awesome • Lot of useful visualisation tools are ready to be used

• Generalizations and Interactions (future work)

THANK YOU FOR THE COOL (SCHOOL) EXPERIENCE

Big thanks to BRIGHTSOLID for providing the interesting dataset
