Abstract. This paper presents the vision and results of creating a national level cross-domain ontology and ontology service infrastructure in Finland. The novelty of the infrastructure is based on two ideas. First, a system of open source core ontologies is being developed by transforming thesauri into mutually aligned lightweight ontologies, including a large top ontology that is extended by various domain specific ontologies. Second, the ONKI Ontology Server framework for publishing ontologies as ready to use services has been designed and implemented. ONKI provides legacy and other applications with ready to use functionalities for using ontologies on the HTML level by Ajax and semantic widgets. The idea is to use ONKI for creating mash-up applications in a way analogous to using Google or Yahoo Maps, but in our case external applications are mashed-up with ontology support. 1 A National Ontology Infrastructure The ambitious goal of the National Semantic Web Ontology project (FinnONTO 2003–2007) 1 [1] is to develop a semantic web infrastructure on a national level in Finland. The consortium behind the initiative—37 companies and public organizations—represents a wide spectrum of functions of the society, including libraries, health organizations, cultural institutions, government, media, and education. The project has produced a variety of scientific results, specifications, services, demonstrations, and applications: 1. Metadata standards. Nationally adapted standards for representing metadata in various application fields have been created, e.g. JHS 158 2 and [2]. 2. Core ontologies. Several core ontologies 3 have been developed in order to initiate ontology development processes in Finland.

Metadata creation is one of the major challenges in developing the Semantic Web. This paper discusses how to make provision of metadata easier and costeffective by an annotation editor combined with shared ontology services. We have developed an annotation system supporting distributed collaboration in creating annotations, and hiding the complexity of the annotation schema and the domain ontologies from the annotators. Our system adapts flexibly to different metadata schemas, which makes it suitable for different applications. Support for using ontologies is based on ontology services, such as concept searching and browsing, concept URI fetching, semantic autocompletion and linguistic concept extraction. The system is being tested in various practical semantic portal projects.

The Semantic Web is based on using ontologies for enabling semantically disambiguated data exchange between distributed systems on the web. This requires efficient means for publishing ontologies on the web to ensure the availability, sharing and acceptance of the ontologies. Support services are needed for utilizing ontologies easily and costeffectively in applications and legacy systems lacking ontology support. To address these vital needs, this paper presents the ONKI ontology service which provides ready-to-use “mash-up ” functionalities, such as semantic disambiguation, concept finding and concept fetching as readyto-use web widgets for adding ontology support to e.g. HTML forms using JavaScript. Two implementations of the ONKI Server are presented: ONKI-SKOS for ontologies presented in the Simple Knowledge Organization System (SKOS) language and ONKI-Geo for geographical ontologies with a map interface. The presented ONKI systems are operational on the web, used in the National Finnish Ontology Service. They

This paper presents a prototype of an ontology-based semantic annotation tool Saha. The tool eases the process of creating ontological descriptions of documents by providing a simple user interface that hides the complexity of ontologies from annotators. Saha is used with a web browser, and it supports collaborative distributed creation of metadata by centrally storing annotations, which can be viewed and edited by different annotators. Concepts defined in external ontologies can be imported and used in annotations by connecting Saha to ontology servers. The tool is being tested in practical semantic portal projects.

This article presents the vision and results of creating the basis for a national semantic web content infrastructure in Finland in 2003–2007. The main elements of the infrastructure are shared and open metadata schemas, core ontologies, and public ontology services. Several practical applications testing and demonstrating the usefulness of the infrastructure are overviewed in the fields of eCulture, eHealth, eGovernment, eLearning, and eCommerce. 1 A Semantic Content Infrastructure The Semantic Web 1 is based on a metadata layer that describes the contents and services on the web in a machine “understandable ” way based on ontologies [5, 34]. The idea from the application viewpoint is simple: if the machine understands the contents and services it is dealing with, then better interoperability of web systems can be obtained and intelligent services provided to the end-users. This papers argues that a conceptual “semantic content infrastructure ” is needed for the semantic web, in the same way as roads are needed for traffic and transportation, power plants and electrical networks are needed for energy supply, or GSM standards and networks are needed for mobile phones and wireless communication. A solid, commonly shared infrastructure would make it much easier and cheaper for public organizations and companies to create interoperable, intelligent services on the coming semantic web. In our view, the infrastructure should be open source and its central components be maintained by the public sector in order to guarantee wide usage and interoperability across different application domains and user communities. 1

This thesis explores the possibilities of using the view-based search paradigm to create intelligent search interfaces on the Semantic Web. After surveying several current seman-tic search techniques, the view-based search paradigm is explained, and argued to fit in a valuable niche in the field. To test the argument, OntoViews, a semantic view-based search portal creation tool was designed and implemented, and eight portals with five vastly dif-ferent user interfaces were built using it. Based on the results of these experiments, this thesis argues that the paradigm, particularly as implemented in the OntoViews tool pro-vides a strong, extensible and flexible base on which to built semantic search applications. The particular problems faced in applying view-based search for semantic interfaces are noted, along with explanations on how they were solved in the OntoViews architecture. Finally, directions and ideas for future research are presented for both the paradigm and the implementation architecture, respectively.

Creation of rich, ontology-based metadata is one of the major challenges in developing the Semantic Web. Emerging applications utilizing semantic web techniques, such as semantic portals, cannot be realized if there are no proper tools to provide metadata for them. This paper discusses how to make provision of metadata easier and cost-effective by an annotation framework comprising of annotation editor combined with shared ontology services. We have developed an annotation system Saha supporting distributed collaboration in creating annotations, and hiding the complexity of the annotation schema and the domain ontologies from the annotators. Saha adapts flexibly to different metadata schemas, which makes it suitable for different applications. Support for using ontologies is based on ontology services, such as concept searching and browsing, concept URI fetching, semantic autocompletion and linguistic concept extraction.

This paper discusses Hozo’s functionality for supporting distributed and collaborative construction of ontologies. In a distributed environment, each ontology is revised asynchronously by different developers. In such a situation, one of the key issues is the maintenance of consistency among inter-dependent ontologies. In order to realize consistent distributed development of ontologies, Hozo provides two functionalities: to manage the dependencies between ontologies and to keep and restore consistencies of ontologies when they are changed.

The Semantic Web is based on using shared ontologies for enabling semantically disambiguated data exchange between distributed systems on the web. This requires, from the ontology publisher’s viewpoint, efficient means for publishing ontologies on the web to ensure the availability and acceptance of the ontologies. From the ontology user’s viewpoint, support services are needed for utilizing ontologies easily and cost-effectively in the users ’ own systems that are typically legacy systems without ontology support. This paper presents the ONKI ontology server for addressing these vital needs. For the publisher, ONKI provides a server and a Simple Knowledge Organization (SKOS) compatible lightweight ontology browser with ready-made web interfaces for making ontologies available both for human and machine users. For external legacy and other applications, ONKI provides centralized ontology services for semantic disambiguation, concept finding, and concept fetching. A major contribution of ONKI is to provide these services as ready-to-use functionalities for creating “mash-up ” applications very cost-efficiently. Two prototypes of the system— ONKI-SKOS for all kinds of ontologies and ONKI-Geo for geographical ontologies with a map mash-up interface—are operational on the web and are currently being successfully used in several pilot applications.
