As a test-bed, a web management system is discussed that provides vocational monographs for occupational guidance. The key idea of the proposed web service based architecture is that the WS of participating members share their vocational monographs and related resources, resulting in the overall system capacity increase. Mechanisms and techniques are presented concerning: an 'information desk', which provides an adaptive search user interface; discovery functions based on semantic representation of the WS' monographs; mining into monographs based on their semantic representation; a metric-based evaluation model for the web monographs; dynamic ranking of retrieved content list; consumption mechanisms for the career counsellors' local WS; e-payment; universal usability access. This analysis can be exploited in the practice of a new Occupational Guidance Policy.

The advancements in computer systems and networks have created a new environment for criminal acts, widely known as cybercrime. Cybercrime incidents are occurrences of particular criminal offences that pose a serious threat to the global economy, safety, and well-being of society. This paper offers a comprehensive understanding of cybercrime incidents and their corresponding offences combining a series of approaches reported in relevant literature. Initially, this paper reviews and identifies the features of cybercrime incidents, their respective elements and proposes a combinatorial incident description schema. The schema provides the opportunity to systematically combine various elements—or cybercrime characteristics. Additionally, a comprehensive list of cybercrime-related offences is put forward. The offences are ordered in a two-level classification system based on specific criteria to assist in better classification and correlation of their respective incidents. This enables a thorough understanding of the repeating and underlying criminal activities. The proposed system can serve as a common reference overtaking obstacles deriving from misconceptions for cybercrimes with cross-border activities. The proposed schema can be extended with a list of recommended actions, corresponding measures and effective policies that match with the offence type and subsequently with a particular incident. This matching will enable better monitoring, handling and moderate cybercrime incident occurrences. The ultimate objective is to incorporate the schema-based description of cybercrime elements to a complete incident management system with standard operating procedures and protocols.
