It is widely recognized that production rules in database systems can be used to automatically maintain derived data such as views. However, writing a correct set of rules for efficiently maintaining a given view can be a difficult and ad-hoc process. We provide a facility whereby a user defines a view as an SQL select expression, from which the system automatically derives set-oriented production rules that maintain a materialization of that view. The maintenance rules are triggered by operations on the view's base tables. Generally, the rules perform Incremental view maintenance: the materialized view is modified according to the sets of changes made to the base tables, which are accessible through logical tables provided by the rule language. However, for some operations substantial recomputation may be required. We give algorithms that, based on key information, perform syntactic analysis on a view definition to determine when efficient maintenance is possible.

The spread of Internet connectivity and advancement of computer hardware increases the power of information technologies to perform practical services in many areas of our everyday life. Agent technologies play essential roles in the design of service-oriented systems such as computer-mediated collaboration, education and training, electronic commerce, information retrieval, and data mining.Agents and multiagent systems also provide a new way of thinking--conceptualizing performance elements as autonomous changes the paradigm for analyzing problems, designing systems, and dealing with complexity, distribution, and interactivity. Concept of agents and multiagent architecture are shaping landscapes of basic research areas including social simulation, games, pervasive and ubiquitous computing, robotics, and user interfaces.The Autonomous Agents and Multiagent Systems (AAMAS) conference series brings together researchers from around the world to share the latest advances in the field. It was initiated in 2002 as a merger of three highly successful related events: the International Conference on Autonomous Agents (AGENTS), the International Conference on Multi-Agent Systems (ICMAS), and the International Workshop on Agent Theories, Architectures, and Languages (ATAL). The AAMAS conference series provides a single, high-profile forum for research in the theory and practice of autonomous agents and multiagent systems. AAMAS 2002, the first of the series, was held in Bologna, followed by AAMAS 2003 in Melbourne, AAMAS 2004 in New York, and AAMAS 2005 in Utrecht. AAMAS 2006 is held in Hakodate, Japan.The five-day event consists of 6 tutorials, 32 workshops, a main conference track, a separate industry paper track with 15 papers, demonstration sessions with 17 demonstrations, an exhibition, and a doctoral mentoring program with 24 students. These and other conference elements are the result of great efforts on the part of many dedicated volunteers. We are grateful to all the AAMAS-06 conference officials and those who worked with them to put together such a successful research meeting.AAMAS 2006 received 553 submissions for the main conference. Each paper was reviewed by at least three program committee members (guided by a senior program committee member). 127 papers were accepted as full 8-page papers, and an additional 123 were accepted as short 3-page papers (acceptance rates of 23.0% for full papers and 45.2% overall).Several innovations were added to this year's conference program and review process. In order to make the review process more interactive, authors were given the opportunity to respond to their reviews prior to the discussion phase and final decisions. In many cases, the reviews, and sometimes the decisions, were altered as a result. In addition, we introduced awards for "best program committee member" and "best senior program committee member" in recognition of the exceptional time and effort contributed by our program committee.At the conference itself, for the first time, the emphasis was on poster presentations as the main form of technical exchange. All accepted papers were presented at poster sessions, with just about half of the full papers presented orally in two parallel tracks. The oral presentations were chosen primarily so as to provide a broad representative of the accepted papers. The goal of this format was to allow for more focused oral sessions while maximizing the opportunity for one-on-one detailed technical exchanges at the posters.

Business process management technology is becoming increasingly popular, resulting in more and more business process models being created. Hence, there is a need for these business process models to be managed effectively. For effective business process model management, being able to efficiently query large amount of business process models is essential. For example, it is preferable to find a similar or related model to customize, rather than building a new one from scratch. This would not only save time, but would also be less error-prone and more coherent with the existing models of the enterprise. Querying large amounts of business process models efficiently is also vital during company amalgamation, in which business process models from multiple companies need to be examined and integrated. This paper provides: an overview of the field of querying business process models; a summary of its literature; and a list of challenges (and some potential solutions) that have yet to be addressed. In particular, we aim to compare the differences between querying business process models and general graph querying. We also discuss literature work from graph querying research that can be used when querying business process models.

Current approaches for service discovery are based on semantic knowledge, such as ontologies and service behavior (described as process model). However, these approaches still remain with a high selectivity rate, resulting in a large number of services offering similar functionalities and behavior. One way to improve the selectivity rate and to provide the best suited services is to cope with user preferences defined on quality attributes. In this paper, we propose and evaluate a novel approach for service retrieval that takes into account the service process model and relies both on preference satisfiability and structural similarity. User query and target process models are represented as annotated graphs, where user preferences on QoS attributes are modelled by means of fuzzy sets. A flexible evaluation strategy based on fuzzy linguistic quantifiers (such as almost all) is introduced. Then, two families of ranking methods are discussed. Finally, an extensive set of experiments based on real data sets is conducted, on one hand, to demonstrate the efficiency and the scalability of our approach, and on the other hand, to analyze the effectiveness and the accuracy of the proposed ranking methods compared to expert evaluation.

Selecting and ranking business processes with preferences: an approach based on fuzzy sets

Active XML (AXML, in short) provides a declarative framework for data and service integration over the Web. In this paper, we present a framework for generation of AXML Web services for materializing the dynamic content of Web pages in data intensive Web sites. In our framework, the dynamic content of a Web page is defined as a (virtual) view, and the view is specified with the help of a set of correspondence assertions, which specifies the semantic mapping between the XML view schema and the base sources schemas. This paper focuses on an algorithm that automatically generates, based on the view's correspondence assertions, the Web service that materializes the view's content.

In this work we study the problem of how to incrementally maintain materialized XML views of relational data, based on the semantic mappings that model the relationship between the source and view schemas. The semantic mappings are specified by a set of correspondence assertions, which are simple to understand. The paper focuses on an algorithm to incrementally maintain materialized XML views of relational data.

A mapping-driven approach for sql/xml view maintenance

In the context of the Semantic Web, a domain ontology may be used to provide the necessary support for linking together a large number of heterogeneous data sources pertaining to a same domain. In this paper, such data sources are first described as local ontologies. Then, each local ontology is rewritten as an application ontology, whose vocabulary is restricted to be a subset of the vocabulary of the domain ontology. Application ontologies enable the identification and the association of semantically corresponding concepts, and thereby help information discovery and retrieval, and also data integration. The main contribution of this paper is a strategy to automatically generate applica- tion ontologies, considering a set of local ontologies, a domain ontology and the result of the matching between each local ontology and the domain ontology. The proposed strategy also enables the automatic generation of mappings between the domain ontology and the application ontologies, and between each application ontology and its corresponding local ontology, which are used to query the data sources through the domain ontology.

The growth of the number of published services rendered searching for a specific service within repositories a critical issue. In this paper, we present an approach to extend structure-based service discovery by making it sensitive to user preferences over service quality defined at different granularity levels of the service structure.
