This paper presents different XML-based techniques for exchanging information between the constituents of a multi-agent system. We expose a multi-agent infrastructure – called Omega – that can be considered as a hierarchical space of distributed objects set those models the Web resources. We suggest an XML/RDF-based model that can be used as a common approach for serialization and metadata description of the objects processed by the agents. Diverse relationships that can be established between the entities of a multi-agent system will also be expressed by different RDF constructs.

We present a system based on the need of special infrastructure adequate to software agents to operate, to compose and make sense from the contents of the Web resources through the development of a multi-agent system oriented services interactions. Our method follows the different construction ontology techniques and updates them by extracting new terms and integrate them to the ontology.It is based on the detection phrases via the ontological database DBPedia. The system treats each syntagme extracted from the corpus of messages and verifies whether it is possible to associate them directly to a DBPedia knowledge. In case of failure, these service agents interact with each other in order to find the best possible answer to the problem, by operating directly in the phrase, trying to semantically modify it, until the association with ontological knowledge becomes possible. The advantage of our approach is its modularity : it is both possible to add / modify / delete a service or define a new one, and then influence the outcome product. We could compare the results extracted from a heterogeneous body of messages from the Twitter social network with Tagme method, based mainly on storage and annotation of encyclopaedic corpus.

How to build intelligent robust applications that work with the information stored in the Web is a difficult problem for several reasons which arise from the essential nature of the Web: the information is highly distributed, it is dynamic (both in content and format), it is not usually correctly structured, and the web sources will be unreachable at some times. To build robust and adaptable web systems, it is necessary to provide a standard representation for the information (i.e., using languages such as XML and ontologies to represent the semantics of the stored knowledge). However, this is actually a research field and usually most web sources do not provide their information in a structured way. This chapter analyzes a new approach that allows us to build robust and adaptable web systems by using a multi-agent approach. Several problems, including how to retrieve, extract, and manage the stored information from web sources, are analyzed from an agent perspective. Two difficult problems will be addressed in this chapter: designing a general architecture to deal with the problem of managing web information sources; and how these agents could work semiautomatically, adapting their behaviors to the dynamic conditions of the electronic sources. To achieve the first goal, a generic web-based multi-agent system (MAS) will be proposed, and will be applied in a specific problem to retrieve and manage information from electronic newspapers. To partially solve the problem of retrieving and extracting web information, a semiautomatic web parser will be designed and deployed like a reusable software component. This parser uses two sets of rules to adapt the behavior of the web agent to possible changes in the web sources. The first one is used to define the knowledge to be extracted from the HTML pages; the second one represents the final structure to store the retrieved knowledge. Using this parser, a specific web-based multi-agent system will be implemented.
