CAPER Methodology


The following diagram shows the organisation of the CAPER project Work Packages. At the heart of the project strategy is the critical user focused Work Package 8: Systems Integration and End-User Trials.



The Analysis and Design Work Package block is targeted at engaging the LEA end users in order to understand their functional needs (WP2), how they can cooperate and share information (WP3), and within what legal and procedural framework they may acquire, process and exploit information from multiple sources (WP7)
The Research and Development Work Package Block aims to turn the LEAs requirements into tools to acquire information from existing and open sources (WP4), provide the tools to analyse multilingual and multi-format data seamlessly (WP5) and finally to transform this information into useful knowledge (WP6).
The project management and coordination package (WP1) will drive the correct execution of the Analysis and Design, and, Research and Development Blocks ensuring that in the execution of WP8 with the LEAs expectations are met and adequate technology is developed.
Finally, in the Dissemination and Exploitation work package (WP9) the results and lessons learnt by the consortium will be brought to bear on the Scientific, Commercial, Law Enforcement, Political, Legal and Technical communities via Workshops, Papers, Seminars, and ideally, whitepaper proposals for legislative and procedural change. All partners will participate in WP9 with priority given to Awareness Raising in the LEA community and Policy Stakeholders.

Standards Based Technologies and Common Architecture

  • A Universal system architecture deployable in all European jurisdictions
  • Based on standardised ICT technologies
  • Comprehensive interfaces for internal and future integration

Focus on Operational Interoperability

  • Application of semantic technologies to enhance organisational interoperability
  • Development of common operational ontolog

Multilingual Analysis

  • A common architectures for linguistic analysis extensible to any other language
  • Open source and best of class, National Language Libraries
  • Combination of rule-based and statistical linguistic techniques for text mining and information extraction
  • Introduction of translation functionalities to offer a cross-lingual information extraction and text-mining system
  • Allow searches to be performed across languages via alignment of lexical resources

Multimedia Analysis

  • Although 80% of open source information is textual; video, image and audio content is equally valuable
  • High performance video and image processing will be implemented
  • Audio content in any CAPER input source will be reduced to text and later analysed as text
  • Biometric data detection will also be included in the CAPER project to allow the identification of specific persons in the information acquired (i.e. faces and voice prints)
  • The Internet is not just HTML. Support multiple document formats (e.g. PDF, DOC, etc.) will be supported

Visual Analytics

  • Innovative use of fused data from closed and open sources will allow one to infer conclusions from the other
  • Creation of Visual Analytics display models specifically tailored to the participating Law Enforcement Agencies
  • Application of Visual Analytics techniques developed for financial institutions in the Law Enforcement and Investigation scenario
  • Integration of semantic analysis technologies with Web data mining techniques

User, not Technology, Focused


  • The CAPER project will focus on the user LEA needs, not the technology. The innovative approach to combining multilingual, multimodal content with semantics for interoperability will provide the users with greater vision and hence better investigative tools.

The CAPER system will be capable of providing “Early Warnings” of trends emerging in the media and Internet and provide User LEAs with an option for proactive rather than reactive prevention.
