- The semantic web dates back to 2001 and a number of tools, and representational forms are proposed and defined. However, the challenges of the semantic web are still largely unfulfilled, in the opinion of the authors. What is proposed here is a synthesis of ideas and techniques aimed a presenting the user with a much more structured search result that can expose the relationships contained within them. This does not increase semantic search, but can provide a much richer view for the user to apply human understanding though exposing the semantics represented by the structure within search results.

Konferensbidrag (refereegranskat)abstract
- The semantic web uses ontologies to improve searching since ontologies provide a richer semantic model of content by expressing terms and relationships. However, a problem with the web is the large number of ontologies, which complicates searching. To maximize the capability of the search, the ontologies need to be combined to obtain complex answers. Usually, the ontologies are created without following any guidelines and, therefore, combining them is not a simple task, especially when ensuring a consistent result. We propose using meta-agents on top of software agents in a multi-agent system to resolve the use and the combination of multiple ontologies and to enable searching and reasoning. The software agents search for parts in the ontologies corresponding to the user-request and meta-agents combine the results from the agents. The meta-agents also partition the ontologies into consistent sets and then combine multiple ontologies into meaningful and logically consistent structures. For this purpose, we extend an existing mapping and alignment algorithm used for communication between agents. The use of multi-agents gives advantages since they provide a parallel approach and, thereby, efficiently handle large numbers of ontologies in order to accomplishtasks separately.

- Meta-level agents and intelligent agents in multi-agent systems canbe used to search for solutions in networks and graphs where the meta-agentsprovide paths between nodes based on properties of the graph elements given atthe time. A challenge with network problems is finding these search paths whileextracting information in the network within an acceptable time bound.Moreover, this is especially difficult when information is extracted andcombined from several different sources. Reducing time and making the agentswork together requires a plan or an effective algorithm. In this paper wepropose an approach to an event-driven algorithm that can search forinformation in networks using meta-agents in multi-agent systems. The metaagentsmonitor the agents using event-driven communication, acting as a searchmethod and extract the searching for information in networks.

Konferensbidrag (refereegranskat)abstract
- In this paper, we propose an approach usingmeta-agents for monitoring multi-agents and controllingtheir behaviour while moving between states in a network.The meta-agents are built on the agents in the system andthen used to inspect the agents’ behaviour when reachinga result as well as perceiving the reason for that result.Each meta-agent can comprise everything from one agentto dozen or more agents depending on the task assigned tothe system. The benefit of using meta-agents for a multiagentsystem is the ability to provide the fastest waybetween nodes under given circumstances and to handle avast number of nodes in graphs and networks such astravelling salesman problem (TSP).

Using Multi-Agent System for Business Applications in Multilingual Ontologies

Konferensbidrag (refereegranskat)abstract
- In e-business, ontology technology is used for e-commerce and e-services. The ontologies are specifications of syntax and semantics of information, which provide a shared vocabulary to facilitate online services. For some requests, multiple ontologies are required to solve a problem, like for e-tourism. However, there are problems with using several ontologies. For example, finding and using the ontologies depends on the language used in the ontologies, and matching techniques. The matching includes word correspondence to the users' request and the equivalence between the ontologies. The matching is difficult due to differences between ontologies resulting from the lack of standards and development guidelines. This paper presents a multi-agent system wherein the agents use the users' request to search for multilingual ontologies. From the search results, the system facilitates communication between the users input and the ontologies to accomplish the request, which can be booking a train ticket or an event. Meta-agents keep track of the agents and manage the user-system communication.

Indirect Alignment between Multilingual Ontologies : A Case Study of Korean and Swedish Ontologies

- The existing ontology alignment methods have been trying to automatically obtain semantic correspondences between ontologies. However, they assume that all elements of source ontologies are written by identical languages. In this paper, we have introduced a theoretical idea for building indirect alignment between multilingual ontologies.,Thereby, a novel architecture to reuse and compose alignments between ontologies has been designed. For a simple case study, we have collected two multilingual ontologies written by Korean and Swedish languages.
