This paper describes a content enabling system that provides deep semantic search and information access to large quantities of distributed multimedia data for both experts and general public. It provides with a language independent search and dynamic classification features for a broad range of data collected from several sources in a number of culturally diverse languages. This system is part of the Online Police Station, launched by the Italian Minister of the Interior in 2006. The Online Police Station uses a virtual reality interface to provide general information and online assistance. Citizens can download forms, make complaints, receive advice and/or report events of an illegal nature. Police specialists can monitor criminal trends to ensure that responses are appropriately focused, and that scarce resources are more effectively employed against criminality. Online Police Station was voted as the Most inspiring good practice for creative solutions to common challenges, at the European eGovernment Awards 2007.

“…Beside Named Entities, locations, time-points, etc, it detects relevant information like noun phrases which comply with a set of pre-defined morphological patterns and whose information exceeds a threshold of significance [8]. The detected terms are then extracted, reduced to their Part Of Speech (Noun, Verb, Adjective, Adverb, etc) and Functional (Agent, Object, Where, Cause, etc) tagged base form [9][10] (see Fig.…”

The revolution in information technology is making open sources more accessible, ubiquitous, and valuable. The international IntelligenceCommunities have seen open sources grow increasingly easier and cheaper to acquire in recent years. Up to 80% of electronic data is textual and most valuable information is often encoded in pages which are neither structured, nor classified. The process of accessing all these raw data, heterogeneous for language used, and transforming them into information is therefore inextricably linked to the concepts of textual analysis and synthesis, hinging greatly on the ability to master the problems of multilinguality. This paper describes SYNTHEMA SPYWatch, a content enabling system for OSINT, which has been adopted by some Intelligence operative structures in Italy to support the Collection, Processing, Exploitation, Production, Dissemination and Evaluation cycle. By this system, operative officers can get an overview of great volumes of textual data, which helps them discover meaningful similarities among documents and find all related information.

“…By including semantic information directly in the dependency grammar structures, the system relies on the lexical semantic information combined with functional relations. Beside Named Entities, locations, time-points, etc, it detects relevant information like noun phrases which comply with a set of pre-defined morphological patterns and whose information exceeds a threshold of significance [13]. The detected terms are then extracted, reduced to their Part Of Speech(NOUN, VERB, ADJECTIVE, ADVERB, etc.)…”
