Ontology matching

We present a literature review regarding articles on ontology matching published in the last decade.It serves the purpose of offering an up-to-date review of the field and showing its evolution trends.Over 1600 papers have been sorted according to a classification framework that we have defined.This framework helps in identifying the distribution of the load work in the last decade.Practitioners have been consulted to contrast and validate the results of the review. The amount of research papers published nowadays related to ontology matching is remarkable and we believe that reflects the growing interest of the research community. However, for new practitioners that approach the field, this amount of information might seem overwhelming. Therefore, the purpose of this work is to help in guiding new practitioners get a general idea on the state of the field and to determine possible research lines.To do so, we first perform a literature review of the field in the last decade by means of an online search. The articles retrieved are sorted using a classification framework that we propose, and the different categories are revised and analyzed. The information in this review is extended and supported by the results obtained by a survey that we have designed and conducted among the practitioners.

Definition of an Ontology Matching Algorithm for Context Integration in Smart Cities.

In this paper we describe a novel proposal in the field of smart cities: using an ontology matching algorithm to guarantee the automatic information exchange between the agents and the smart city. A smart city is composed by different types of agents that behave as producers and/or consumers of the information in the smart city. In our proposal, the data from the context is obtained by sensor and device agents while users interact with the smart city by means of user or system agents. The knowledge of each agent, as well as the smart citys knowledge, is semantically represented using different ontologies. To have an open city, that is fully accessible to any agent and therefore to provide enhanced services to the users, there is the need to ensure a seamless communication between agents and the city, regardless of their inner knowledge representations, i.e., ontologies. To meet this goal we use ontology matching techniques, specifically we have defined a new ontology matching algorithm called OntoPhil to be deployed within a smart city, which has never been done before. OntoPhil was tested on the benchmarks provided by the well known evaluation initiative, Ontology Alignment Evaluation Initiative, and also compared to other matching algorithms, although these algorithms were not specifically designed for smart cities. Additionally, specific tests involving a smart citys ontology and different types of agents were conducted to validate the usefulness of OntoPhil in the smart city environment.

INGENIAS with the Unified Development Process

This chapter introduces the definition of a process for the INGENIAS methodology. It is an adaptation of the unified development process (UDP). The process adopts the organization in phases of the UDP and proposes activities and work products equivalent to the ones of UDP and suitable to develop multi-agent-systems (MAS). As INGENIAS follows a model-driven approach, these activities are largely focused on obtaining a specification of the MAS, conforming to the INGENIAS metamodel. The case study of the conference management system illustrates the application of this process to get a description of the environment and users of the system and the workflows where it will act.

Pentas: Using Satellites for Smart Sensing

Smart environments are an important field of study and have suffered from an important evolution in the last decade. Smart technology makes an intensive use of wireless technology as the way of communicating all the elements of the system, including sensors. This paper tries to show how the use of satellites and radio waves may provide smart characteristics to environments that lack the common wireless technologies usually utilized. A system using Agent Oriented Software Engineering and based on that technology has been constructed and shows the suitability and advantages of the proposal.

A New Similarity Measure for an Ontology Matching System

The purpose of this paper is twofold. It describes a new similarity measure which is applied in a new ontology matching algorithm, OntoPhil that exploits both the lexical and structural information of the input ontologies. The different steps of the algorithm as well as some clarifying examples are also provided. In addition, OntoPhil is also compared and evaluated using the datasets from well-known Ontology Alignment Evaluation Initiative.

Multi-agent systems applied to the field of ornamental plants

The market of ornamental plants is very important and strategical in Galicia and yet is one of the sectors where fewer technological change has been incorporated in recent years. This paper describes a real solution applied to an enterprise of ornamental plant selling and distribution. The solution that we propose uses intelligent agent technologies and ontologies to meet the special needs of an enterprise of this kind. We present the architecture defined with the agents involved in both parties, the plant wholesaler and the plant producers. A description of the ontologies that these agents use to interact is also provided, as well an example of systems behavior. In the final section some relevant issues detected and conclusions will be presented.

An Agent Oriented Development Process for Multimedia Systems

Requirements elicitation is a very difficult task when designing multimedia systems because of its special characteristics. The usual requirements specification process in multimedia development starts with the codification of prototype. After, it is analyzed by the customer to decide whether the application is to be constructed or not. This paper proposes a process specially defined for multimedia development that provides an initial prototype without human codification. The process combines the use of an agent oriented methodology and Alice (a multimedia oriented tool). In addition, a tool that provides support to this process is introduced. Both the process and its supporting tool are used in a simple example which demonstrates the suitability of the approach for multimedia prototype development.

Agent Collaboration Framework

The philosophy of software development has changed significantly in recent years. Build quality software more quickly is imperative in todays market, specially when it has to meet the demands of consumers. Not long ago a development team could consist of only one member, while today this is unthinkable, since the number of members in the development teams increases with the complexity of the actual issues. Collaborative programming or pair programming is one of the more relevant areas at present in providing efficient solutions to the working groups management, in such a way that their impact on the software development process is indisputable. The main purpose of this document is to gather the most relevant aspects of the collaborative models in a collaborative framework based on the use of software agents. In practice, the proposed framework is designed in a generic manner, allowing its extension to other environments and different domains.
