Adaptive information provisioning in an agent-based virtual organization: ontologies in the system

In this paper we consider utilization of ontologies in an agentbased virtual organization. Specifically, in the system flexible delivery of information is to be based on matching of ontologically demarcated resource profiles, work context(s), and domain specific knowledge. In this paper we introduce basic ontologies and their applications.

Measuring Semantic Closeness of Ontologically Demarcated Resources

In our work, an agent-based system supporting workers in an organization is centered around utilization of ontologically demarcated data. In this system, ontological matchmaking, understood as a way of establishing closeness between resources, is one of key functionalities. Specifi- cally, it is used to autonomously provide recommendations to the user, who is represented by her/his personal agent. These recommendations specify, which among available resources are relevant/of interest to the worker. In this paper, we discuss our approach to measuring semantic closeness between ontologically demarcated information objects, while a Duty Trip Support application is used as a case study. General description of the algorithm is followed by a recommendation example based on support for a worker who is seeking advice in planning a duty trip.

On Human Resource Adaptability in an Agent-Based Virtual Organization

This paper discusses subsystem responsible for providing human resource adaptation through software-supported training in an agent-based virtual organization. Attention is focused on the requirements, functionalities and components of this subsystem and its interactions with other parts of the system.

On Resource Profiling and Matching in an Agent-Based Virtual Organization

In our work we are designing agent based support for workers in a virtual organization. In the system under development, all resources are to be ontologically demarcated and utilized through semantically- driven information processing techniques. This paper contains preliminary considerations concerning resource profiling and ontological matching methods which we intend to utilize within the system. Two applications that we are currently developing are used to illustrate the proposed approach.

Ontological matchmaking in a Duty Trip Support application in a virtual organization

In our work, an agent-based system supporting workers in fulfilling their roles in a virtual organization has as its centerpiece ontologically demarcated data. In such system, ontological matchmaking is one of key functionalities in provisioning of personalized information. Here, we discuss how matchmaking will be facilitated in a duty trip support application. Due to the nature of the application, particular attention is paid to the geospatial data processing.

Infrastructure for Ontological Resource Matching in a Virtual Organization

In our earlier work we have outlined general approach to ontological matchmaking in an agent-based virtual organization. The aim of this paper is to describe in details how matchmaking is to take place within the system under construction. The Grant Announcement application is used to illustrate the proposed approach. Questions concerning efficiency of matchmaking will be addressed and in this context a distinction between asynchronous and synchronous matchmaking will be proposed.

Adaptability in an Agent-Based Virtual Organization – Towards Implementation

Ability of an organization to adapt to change is one of its important features. When a real-world organization is transformed into a virtual one, with a help of software agents and ontologies, it is important to specify how adaptability can be achieved. In our earlier work we have conceptualized, on a general level, adaptability in an agent-based virtual organization. The aim of this chapter is to discuss how agent adaptability can be implemented.

Considering Resource Management in Agent-Based Virtual Organization

In this chapter we discuss a system designed to support workers in a virtual organization. The proposed approach is based on utilization of software agents and ontologies. In the system all Users are represented by their Personal Agents that help them in fulfilling their specific roles. At the same time all entities that the organization is comprised off (human and non-human) are represented as instances of resources in an ontology of the organization. Furthermore, each resource is associated with one or more profiles and these profiles are adapted to represent changes in resources (e.g. new experience/knowledge gained by a human resource, or approval of a duty trip application). The aim of this chapter is to describe basic functions of our system with special attention paid to software agents, their roles and interactions as well as utilization of ontologies in support of worker needs.
