Status

• Text mining, natural language understanding, recognition of content in multimedia ...: – Opportunities to monitor information

• Web content• Secured information• ...

23/9/10 SRC'10 3

Status

– Opportunities to search, mine and fuse information:

• To discover trends and patterns• For decision making, prediction, analysis and

intervention

23/9/10 SRC'10 4

Examples of applications• Protection of citizens for harmful content:

– Webpages (e.g., protect children - PuppyIR EU FP7)

– Spam and phishing mails (e.g., protect citizens, AntiPhish EU FP6)

– False information (e.g., protect customers)– Defamation (e.g., protect companies, individuals)

• Protection of groups: – Intelligent surveillance (e.g.,

video surveillance)www.kansascitypi.com

Examples of applications

• Protection of European companies: – Against industrial espionage, unlawful copying

• Protection of nations: – Against terrorist groups– Restoring security at moments of crisis: fusion,

filtering and generation of information

Issues• Recognition of content: but

– Heterogeneous sources, different languages, media

– Fraudulent scams cloak content– Fraudulent scams change strategies continuously– Content can be unreliable (credibility)

Can you trust it?

Issues

• Linking of content: – Interoperability, integration, interconnectability– Linking based on low-level features

23/9/10 SRC'10 8

Needs

• ICT– Robust and reliable extractors (text, speech,

images, video...)– Robust and reliable linking technologies

(connecting the dots ...)• Includes also disambiguation

– Adaptable to different languages and media with minimum of human intervention

– At system level: interoperability

Response

• ICT Technologies:– Knowledge methodologies maturing: ontologies,

semantics, machine learning, data/text/graph mining, joint classification, alignment, ...

– Probabilistic models for reasoning– Latent class models for discovering hidden

semantics• FP7: European Security Research programme:

– Develop technologies and knowledge to ensure security of citizens from threats such as terrorism, (organised) crime, natural disasters and industrial accidents
