In this paper, we present h-match, an algorithm for dynamically matching distributed ontologies. By exploiting ontology knowledge descriptions, h-match can be used to dynamically perform ontology matching at different levels of depth, with different degrees of flexibility and accuracy. h-match has been developed in the Helios framework, conceived for supporting knowledge sharing and ontology-ad...

AgreementMakerLight (AML) is an automated ontology matching system based primarily on element-level matching and on the use of external resources as background knowledge. This paper describes its configuration for the OAEI 2015 competition and discusses its results. For this OAEI edition, we focused mainly on the Interactive Matching track due to its expansion, as handling user interactions on ...

An ontology matching method (or a matcher) aims at matching every entity (or concept) in one ontology to the most suitable entity (or entities) in another ontology. Usually it is almost impossible to find a perfect match in the second ontology for every entity in the first ontology, so a matcher generally returns a set of possible matches with some weights (uncertainty) attached to each pair of...

To bring the Life Sciences domain closer to a Semantic Web realization it is fundamental to establish meaningful relations between biomedical ontologies. The successful application of ontology matching techniques is strongly tied to an effective exploration of the complex and diverse biomedical terminology contained in biomedical ontologies. In this paper, we present an overview of the lexical ...

The paper proposes the approach to cope with the maintenance of dynamically changing resource ontologies of autonomously maintained, distributed, heterogeneous, wrapped information resources and their mappings to common mediator IS ontology. The approach intends to do the work in economical way reducing efforts to matching and aligning only modified ontology elements. Proposed is ontology model...

This document presents an evaluation methodology for the assessment of quality results produced by ontology matchers. In particular, it discusses: (i) several standard quality measures used in the ontology matching evaluation, (ii) a methodology of how to build semiautomatically an incomplete reference alignment allowing for the assessment of quality results produced by ontology matchers and (i...

The Semantic Web is a mesh of information linked up such that it can be easily processed by machines. The focus of semantic web is to share data instead of documents and the ontologies act as the mainstay of the semantic web. Ontologies are used to represent domain knowledge in semantic web. As ontologies have many applications in various prominent fields, ontology reuse is becoming increasingl...

User participation is a promising approach for Ontology Matching; however, determining the most representative pairs of entities is still a challenge. This paper delineates an Ontology Matching approach for user participation employing a clustering algorithm.

The AgreementMaker system is unique in that it features a powerful user interface, a flexible and extensible architecture, an integrated evaluation engine that relies on inherent quality measures, and semi-automatic and automatic methods. This paper describes the participation of AgreementMaker in the 2011 OAEI competition in four tracks: benchmarks, anatomy, conference, and instance matching. ...

Schema and ontology matching is a critical problem in many application domains, such as semantic web, schema/ontology integration, data warehouses, e-commerce, etc. Many different matching solutions have been proposed so far. In this paper we present a new classification of schema-based matching techniques that builds on the top of state of the art in both schema and ontology matching. Some inn...
