Semantic Web: The Future Starts Today “Industrial Ontologies” Group http://www.cs.jyu.fi/ai/OntoGroup/index.html Agora Center, University of Jyväskylä, 23 May 2003 Industrial Ontologies Group
“Industrial Ontologies” Group: Our History ontologies1978-1984 – We took part in development of the first in USSR Industrial Natural Language Processing System “DESTA”, which included semantic analysis and ontologies; Enabled Semantic AnnotationDiscovery Integration Semantic Web Services1985-1989 - We took part in development of the first in USSR Industrial Automated Natural Language Programming System “ALISA”, which Enabled Semantic Annotation, Discovery and Integration of software components (prototype of today's Semantic Web Services concept);
“Industrial Ontologies” Group: Our History Semantic Web1990-1993 – under name of Metaintelligence Lab. we were piloting concept of a Metasemantic Network (triplet-based (meta-)knowledge representation model) – prototype of today’s RDF- based knowledge representation in Semantic Web; 1994-2000 – various projects with industrial partners, e.g. MetaAtom – “Semantic Diagnostics of Ukrainian Nuclear Power Stations based on Metaknowledge”; MetaHuman – industrial medical diagnostics expert system based on Metaknowledge”; Jeweler – metamodelling and control of industrial processes, etc.; got several research grants from Finnish Academy;
“Industrial Ontologies” Group: Our History 2000-2001 – we have created branches in Vrije Universiteit Amsterdam (heart of Semantic Web activities in Europe) where now working 5 our former team members, in Jyvaskyla University (several tens of researchers) and established research groups in Kharkov (Ukraine) on Data Mining, Educational Ontologies, Telemedicine, etc. Semantic Web2001-2003 – we took part in MultiMeetMobile Tekes Project, in InBCT Tekes Project in Tempus EU Compact Project in (or in cooperation with) University of Jyvaskyla where we further promote Semantic Web concepts.
Industrial Ontologies Group: Important Objective For us there are no doubts about the possibilities, which Semantic Web opens for industry. that is why one important objective of our activities is to study appropriate industrial cases, collect arguments, launch industrial projects and develop prototypes for the industrial companies to not only believe together with us but also benefit from the Semantic Web.
Why and Where Semantic Web ? WWW Business Knowledge Management more then 3,000,000,000 web-pages “Information” burst ICT needs comprehensive resource management technology Needs for integration of businesses Web Services for e-Business Standardization and Interoperability problems Consolidate and reuse experience Standardize knowledge sharing technology Needs for the intelligent tools to use human’s knowledge
Approach: Semantic Web “The Semantic Web is a vision: the idea of having data on the Web defined and linked in a way that it can be used by machines not just for display purposes, but for automation, integration and reuse of data across various applications” http://www.w3.org/sw/ The Semantic Web is an initiative with the goal of extending the current Web and facilitating Web automation, universally accessible web resources, and the 'Web of Trust', providing a universally accessible platform that allows data to be shared and processed by automated tools as well as by people.
Word-Wide Correlated Activities Semantic Web Grid Computing Web Services Agentcities Agentcities is a global, collaborative effort to construct an open network of on-line systems hosting diverse agent based services. WWW is more and more used for application to application communication. The programmatic interfaces made available are referred to as Web services. The goal of the Web Services Activity is to develop a set of technologies in order to bring Web services to their full potential FIPA FIPA is a non-profit organisation aimed at producing standards for the interoperation of heterogeneous software agents. Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation Wide-area distributed computing, or "grid” technologies, provide the foundation to a number of large-scale efforts utilizing the global Internet to build distributed computing and communications infrastructures.

Web Resource/Service Integration: Server-Based Transaction Monitor ServerClient Server Web resource / service Web resource / service Transaction Service TM wireless
Web Resource/Service Integration: Mobile Client-Base Transaction Monitor Server Client Server Web resource / service TM Web resource / service wireless
The conceptual scheme of the ontology-based transaction management with multiple e-services Terziyan V., Ontological Modelling of E-Services to Ensure Appropriate Mobile Transactions, In: International Journal of Intelligent Systems in Accounting, Finance and Management, J. Wiley & Sons, Vol. 12, 2003, 14 pp.
Ontology-Based Transaction Management for the Semantic Web Consider two basic transaction management architectures in mobile environment depending on where the Transaction Monitor (TM) will be located. First one (Server-Based) assumes that TM will be located in server side, e.g. within some transaction management service. Second one (Client- Based) supposes that TM is located in mobile client terminal. The first objective will be to provide and study an integrated mobile transaction management architecture for the Semantic Web applications, which will combine the best features from these two architectures by intelligent switching from one architecture to another one depending on current application context. There is already some ontological support for Semantic Web resources and services interoperability based on OWL, DAML-S. However to be able to manage transactions in Semantic Web across multiple resources (or services) there will not be enough only ontologies for semantic annotations of these resources; there will be evident need of the ontology for the Semantic Web transactions itself. The second objective will be developing pilot ontology for the RDF-based semantic annotation of mobile transactions in the Semantic Web.

Machine-to-Machine Communication P2P ontology Heterogeneous machines can “understand” each other while exchanging data due to shared ontologies
Semantic Web-Supported Sharing and Integration of Web Services Different companies would be able to share and use cooperatively their Web resources and services due to standardized descriptions of their resources. P2P ontology
Corporate/Business Hub Publish own resource descriptions Advertise own services Lookup for resources with semantic search Automated access to enterprise (or partners’) resources Hub ontology and shared domain ontologies Seamless integration of services Software and data reuse Partners / Businesses What parties can do: What parties achieve: Ontologies will help to glue such Enterprise-wide / Cooperative Semantic Web of shared resources Companies would be able to create “Corporate Hubs”, which would be an excellent cooperative business environment for their applications.
Web Services for Smart Devices Smart industrial devices can be also Web Service “users”. Their embedded agents are able to monitor the state of appropriate device, to communicate and exchange data with another agents. There is a good reason to launch special Web Services for such smart industrial devices to provide necessary online condition monitoring, diagnostics, maintenance support, etc. OntoServ.Net: “Semantic Web Enabled Network of Maintenance Services for Smart Devices”, Industrial Ontologies Group, Tekes Project Proposal, March 2003,

Industrial Ontologies Group Future Plans: Applications of Wireless Semantic Web Industrial Ontologies Group Future Plans: “Applications of Wireless Semantic Web”
Semantically annotated personal data Virtually all resources have to be a marked with semantic labels that show explicitly the meaning of the resource (piece of data, fact, value etc.) It will make possible for user: –To organize own view on data and use it for data management –To access own and other’s resources with semantic queries using “terms” of own model –To be able integrate data from other sources (semantics of data is important, data can be converted/translated if needed and appropriate mapping exists) Applications will have: –Possibility to discover and operate on user information and preferences –Possibility to share information with applications on other devices and elsewhere My data description model (ontology) Common data semantic descriptions (ontologies) My resources and their descriptions Personal data-view Applications mapping between views Other people’s data-views User data becomes available to variety of applications and other people Semantic Web Inside™ Commitment to ontology
Modelling of personal data views Simple user data view (as is in most of mobile phones) Model of user’s data and other resources: - Contacts (phone numbers, names etc.) - Notes (some pieces of text) - Calendar (with some events assigned) It is rather simple, but a good beginning for own data model creation….. Data to store in every instance of defined information model Actually, this model is a simple ontology of “Personal Data” domain. Using developed standard ontology languages it will be stored in universal data format.
Building own data model… added slot (property/field) inherited slot
Building own data structure added slot (property/field) inherited slot Inherited properties “Relative is a kind of friend” Links to other data entities
Building own data structure added slot (property/field) inherited slot Customized data model: new kinds of data new kinds of data new kinds of representation new kinds of representation rules and constraints for data etc. rules and constraints for data etc. association of data with applications association of data with applications Customized data model: new kinds of data new kinds of data new kinds of representation new kinds of representation rules and constraints for data etc. rules and constraints for data etc. association of data with applications association of data with applications
Using generated interface Data view is described as an ontology which contains all needed information about data structure. User interface is built dynamically from ontology: Fields for data Form layout, types of controls (e.g. picture, checkboxes etc.) Rules for data that can check some constraints, invoke actions, perform calculations – whatever! For described data model forms are generated
Access your data quickly and easily… Terziyan’s Contact data Event data Possibilities to build flexible, easily customizable data management applications are great. Just click to open Every piece of data is somehow described in user’s terms from data-view ontology. Links between data make it easy to find needed information
Customizable personal information management environment Personal data “view”: Development of own view on personal data Reusing of existing views (join, modify, extend) Links between personal and some “global” ontology Sharing of data: Applications use data and do it correctly (because of semantics assigned) Applications can exchange data with external sources Data can be translated in respect of its semantics (for localization, between different data views, to fit some requirements etc.) In such environment even development of own applications/scripts can be possible Ontologies and Semantic Web will enable such kind of applications Easy-to-use, flexible, customizable data management for users Repositories of ready data-views Note: Protégé-2000 ontology development and knowledge acquisition tool was used for demonstration Enabled collaboration and interoperability
OntoCache General ontology Semantic annotations of Web-services (or any other resources) based on shared ontologies enhance much the efficiency of their search/browsing from the PDA. Local ontology adapts permanently to the user preferences. Personal ontology
OntoCache: benefits Technology that supports future Ubiquitous Semantic Web Effective filtering of wide variety of Web-resources Support for semi-natural queries Context and preferences- based adaptation
Phone calls are also possible between mobile terminal agents. They are performed without human participation in order to exchange local information. Agent-to-Agent communication Semantic annotation of the local data enables its intelligent processing by software. Ontologies provide interoperability between heterogeneous peers.
Agent-to-Agent communication Health Cooking Business ? Whatever semantics enables intelligent data processing ontological relations define possible cooperation between domain agents shared ontology ensures interoperability

BANK : Data annotation In order to make miscellaneous data gathered and used later for some processing, every piece of data needs label assigned, which will denote its semantics in terms of some ontology. Software that is developed with support of that ontology can recognize the data and process it correctly in respect to its semantics.
