We are in the process of developing an agent and ontology-based Duty Trip Support application. The goal of this paper is to consider issues arising when implementing such a system. In addition to the description of our current implementation, which is also critically analyzed, other possible approaches are considered as well.
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 u...
In this paper we consider the adaptability in an agent-based Virtual Organisation (VO). After introducing the system and the need for adaptive behaviours, human resource adaptability in particular, we discuss how the goal of 'agent adaptation' can be implemented. Specifically, we propose how agent behaviours can be added into/removed from/replaced...
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...
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 compris...
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 me...
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 v...
In this paper we consider utilization of ontologies in an agent-based 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.
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 efficienc...
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.
In our work we consider resource management in a virtual organization. The proposed approach is based on utilization of ontologies to represent structure of the organization and its domain of operations, and software agents that support workers in fulfilling various roles within the organization. In this paper we consider processes involved in a ge...
In this note we present a top level overview of resource management in an an agent-based virtual organization. To illustrate its main features we discuss processes involved in a project being introduced into the organization.
Large body of recent work has been devoted to multi-agent systems utilized in e-commerce; in particular, autonomous software agents participating in auctions. In this context we modify a model agent-based e-commerce system so that it can serve as an airline ticket auctioning system. Such a system can be then combined with a Travel Support System th...
Internal data representation is one of interesting issues in designing an agent based airline ticket auctioning system. Obviously, such system could utilize directly the airline mandated data format. However, if purchasing airline tickets is a part of a travel support system that utilizes ontologically demarcated content, then also air travel data...
Advancement of usage of ontologies requires not only creation of new ontologies (e.g. in a top-down manner), but also ontological support for existing domain-specific real-world standards. One of such standards that gains popularity is the Open Travel Alliance (OTA) messaging system that defines, among others, the way that entities should communica...
Further development of the World Wide Web depends on the existence of data stored in a machine-consumable format. This in turn requires the design of domain ontologies, the availability of information described with these ontologies, and agents for exploiting this information. In this paper we describe our attempt at designing travel ontology and i...
This paper describes our efforts to semantically describe travel-related documents on the Internet. We focus on the areas of lodging and gastronomy, with allowance for further expansion into other aspects of the world of travel. Based on an analysis of currently-available data, we develop hotel ontology. Furthermore, we explicitly define an ontolog...
There exist a number of areas where autonomous software agents are expected to play an important role as a new generation of tools facilitating efficient management of information. One such area that was not considered thus far is support for student mobility. While not much of an issue within the US, student mobility is one of the important object...

... memory and/or battery). It will be also desirable that (3) the selected solution will be flexible enough to modify the "reasoning capabilities" of an agent (or a selected group of agents) without taking the whole system down (see, also Frackowiak et al. (2009) andFrackowiak et al. (2008)). Taking these limitations into account, we have considered three approaches to inserting "intelligence" into software agents. ...

" Here, consider the fact that while for most (grant) announcements anyone should be able to read them, access to modify (write or delete) grant announcements should be restricted to authorized entities. When considering the resource profile we also follow our work in the design of the Travel Support System (TSS) [7]. There, a profile of a human was defined as a set of data about a given individual and his opinions which reflect his attitude toward certain features of objects, or toward objects demarcated within the system [5]. ...

... In order to effectively locate and match candidates and positions internally and externally within an organization, it is important and possible to use semantic technology [2,3] because we can provide seamless matching in a smarter way. Qualitative and quantitative justification for the matching of available and required skills and competencies needed to improve the decision-making process for recruitment and the process of assigning people to tasks and teams [4], are provided by using semantic technologies in job vacancies and candidate profiles. In addition, the semantic description of candidate profiles in an organization facilitates the management of individual skills and competencies in the human resources available and is proportionate to the overall vision of available organizational skills. ...

... Nevertheless, one can find a number of projects that attempted at using jointly agent systems and semantics. Let us list a few examples, which illustrate general trends: (i) Magenta Technologies: Multi-agent Systems for Ocean logistics -an agent-semantic system solving scheduling problem [130]; (ii) Semanticbased Travel Support System: where semantic representation of "world of travel" is used [129,128]; (iii) Semantic based Workers support system: based on ontologies of organization, travel, research interests, used to support workers in a virtual organization [127,126,125]; and (iv)Agent-semantic system for management of resources in computational grids (or clouds) [123,121]. Here, an ontology of numerical linear algebra has been developed [120], and possibility of combining agents+semantics+multicriterial analysis has been studied [119]. ...
