Brief overview of technical challenges:

Collecting and processing data in real-time

Filtering (spam detection / influential Tweets / Influential Twitter Accounts) and aggregating the datasets

Assessing the integrity of the datasets

Potential need to store massive datasets (MongoDB)

Previous Work Technical Considerations Retrieval of Datasets

Page 8: EMOTIVE: Data Collection

DATASETS based on UK REGIONS

Retrieve geo-tagged tweets only (small minority) …other ways of restricting Tweet retrieval to UK based Tweets

Use look-up lists of entities / places / cities / main-roads / etc. in the UK (tricky; King’s Cross station vs. King’s Cross city in Sydney)

Complementary Approach; differences in dialects, e.g. Nottingham / Nottinghamshire, Newcastle, Manchester, London,… (identify heuristics & automated classification)

Location inferred from the event

Page 9: EMOTIVE: Data Collection

DATASETS based on NATIONAL SECURITY RISKS

Hashtags # concerning national security starting point; threats list compiled by Cheong and Lee (2011)

Tweet collection operating at all times, collect Tweets before events happen: preselect known events such as the G20 or G8

Also collect datasets relating to emergencies; i.e. floods in UK

understanding the “lifecycle” of such an event on Twitter Sentiment of Terse natural language…

Exploratory Data Collection: M6

Previous Work Technical Considerations Retrieval of Datasets

Chris Halpin @KatsJonouchiThis M6 toll thing... If you're going to try and blow up a coach, you wouldn't choose a Megabus, surely...

Armani Music @ArmaniBmusicSomeone was seen pouring a liquid in something that made fumes on a Mega bus on the M6 Toll. I will full on wee myself if it's a pot noodle.

Johnny O'Grady @JohnnnnyyyyyyyyWatching the news in Tescos, bit confused about what's happened on the M6 toll road

Ellie Henderson @EllieH_86Distracted at work watching the M6 Toll footage on the news.#M6Toll

Ian Watson @IanWatoopM6 Toll. "I picked the wrong day to give up smoking!". #Megabus

Splashy♥ ❤@_Splashy_2001, terrorists hijack planes. 2012, terrorism alert on a Megabus on the M6 toll. This recession has hit hard.

Zora Suleman @ZoraSulemanPolice confirm .. the closure of the M6 toll road was caused by an Electric cigarette

Exploratory Data Collection: Kings Cross Station

Previous Work Technical Considerations Retrieval of Datasets

@Pearcesport|17 days before Olympics, and Kings Cross station, one of main gateways to Olympic Park, has been closed this morning due to overcrowding

@thefashionturdGot evacuated from Kings cross st pancras! not half as scary as Boris' Olympic messages that are being played into tube stations though...

@corrina_kylieKings Cross is filled with scary characters, I'll say that much.

@subhajitbSome pretty angry people outside Kings Cross tube station#fasterhigherstrongerhttp://twitter.com/subhajitb/status/222599112976105472/photo/1

@MoniqueBabyxRIP to the 18 year old boy who died in kings cross. so sad, so young, so early. prayers go to the innocent family.

Taxonomy / Ontology 1

Make a Taxonomy first This establishes correct relationships Then create ontology (OWL)

Scope1. Civic unrest? UK?2. Emotions

Range of Language for Ontology 1 ‘normal’ English Urban slang Street talk Text language

Exploring Taxonomy / Ontology

Page 13: EMOTIVE: Data Collection

Vocabulary sources

Thorne, T. Dictionary of contemporary slang

www.urbandictionary.com www.odps.org www.chavscum.co.uk etc.

and from Twitter feeds and archives

Exploring Taxonomy / Ontology

Page 14: EMOTIVE: Data Collection

Taxonomy / Ontology 2

A number of ‘lists’ of emotions exist: Project Muse Art and architecture thesaurus Tate Gallery Etc.

Exploring Taxonomy / Ontology

Page 15: EMOTIVE: Data Collection

Tate galleries – emotion

Exploring Taxonomy / Ontology

Page 16: EMOTIVE: Data Collection

Linguistic and semantic issues

At the extraction stage: Single terms and noun phrases: ‘police car’, etc.

Barriers to understanding Sarcasm and metaphor

Types of relationships between terms: Synonyms Broad to narrow (Classes and subclasses)

Exploring Taxonomy / Ontology

Page 17: EMOTIVE: Data Collection

For example…

Exploring Taxonomy / Ontology

Guns

glock

piece

pistol

etc.

Page 18: EMOTIVE: Data Collection

‘Guns’ is one subclass of ‘Weapons’

Exploring Taxonomy / Ontology

Weapons

Glock

piece

pistol

guns

knives

Page 19: EMOTIVE: Data Collection

The issues and approaches discussed in the context of Twitter, also apply to public Facebook messages.

Other considerations:- Age and Gender detection from Terse natural language- Scope of Communication (social network analysis)- Followers of certain bands / parties

(maybe extreme; neo-nazi, leftist, etc.)

Final Remarks…
