1 Semantic Web: The Future Starts Today
Industrial Ontologies Group Semantic Web: The Future Starts Today “Industrial Ontologies” Group Agora Center, University of Jyväskylä, 23 May 2003

2 “Industrial Ontologies” Group: Our History
– We took part in development of the first in USSR Industrial Natural Language Processing System “DESTA”, which included semantic analysis and ontologies; 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);

3 “Industrial Ontologies” Group: Our History
– 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; – 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;

4 “Industrial Ontologies” Group: Our History
– 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. – 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.

5 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.

6 Why and Where Semantic Web ?
more then 3,000,000,000 web-pages “Information” burst ICT needs comprehensive resource management technology WWW Needs for integration of businesses Web Services for e-Business Standardization and Interoperability problems Business Knowledge Management Consolidate and reuse experience Standardize knowledge sharing technology Needs for the intelligent tools to use human’s knowledge

7 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” 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.

8 Word-Wide Correlated Activities
Semantic Web Agentcities is a global, collaborative effort to construct an open network of on-line systems hosting diverse agent based services. 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 Agentcities Grid Computing 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. FIPA FIPA is a non-profit organisation aimed at producing standards for the interoperation of heterogeneous software agents. Web 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

11 Semantic Web: What to Annotate ?
External world resources Web resources / services / DBs / etc. Web users (profiles, preferences) Shared ontology Web agents / applications Web access devices Smart machines and devices

12 Ontologies: the foundation of Semantic Web
Ontologies are key enabling technology for the Semantic Web “..explicit specification of conceptualization..” Ontology is formal and rich way to provide shared and common understanding of a domain, that can be used by people and machines comment __Thing__ Author public private Access Rights is-a Location Related to Document name Report is-a is-a Web-page uri Subject Instance-of Instance-of O.

21 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.

22 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.

26 Machine-to-Machine Communication
P2P ontology P2P ontology Heterogeneous machines can “understand” each other while exchanging data due to shared ontologies

27 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 P2P ontology

28 Corporate/Business Hub
Hub ontology and shared domain ontologies Partners / Businesses Companies would be able to create “Corporate Hubs”, which would be an excellent cooperative business environment for their applications. What parties can do: What parties achieve: Publish own resource descriptions 2 cases: Integration within enterprise (corporation) Integration between separate businesses Everything remains true for both cases, only terms are changed Software and data reuse Advertise own services Automated access to enterprise (or partners’) resources Lookup for resources with semantic search Seamless integration of services Ontologies will help to glue such Enterprise-wide / Cooperative Semantic Web of shared resources

29 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" OntoServ.Net: “Semantic Web Enabled Network of Maintenance Services for Smart Devices”, Industrial Ontologies Group, Tekes Project Proposal, March 2003,

31 Embedded Maintenance Platforms
Embedded Platform Based on the online diagnostics, a service agent, selected for the specific emergency situation, moves to the embedded platform to help the host agent to manage it and to carry out the predictive maintenance activities Host Agent Maintenance Service Service Agents

32 OntoServ.Net Challenges
New group of Web service users – smart industrial devices. Internal (embedded) and external (Web-based) agent enabled service platforms. “Mobile Service Component” concept supposes that any service component can move, be executed and learn at any platform from the Service Network, including service requestor side. Semantic Peer-to-Peer concept for service network management assumes ontology-based decentralized service network management.

33 Industrial Ontologies Group Future Plans: “Applications of Wireless Semantic Web”

34 Semantically annotated personal data
Virtually all resources have to be 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 with user information and preferences Possibility to share information with applications at other devices and elsewhere My data description model (ontology) Common data semantic descriptions (ontologies) mapping between views Personal data-view Semantic Web Inside™ Commitment to ontology Get ontology of information resources you want to manage as starting point (Design yourself or just download) Extend ontology as you want using visual tools and wizards Use dynamically generated from ontological description user interface (forms, controls etc.) that provides all means for data access. Applications User data becomes available to variety of applications and other people My resources and their descriptions Other people’s data-views

35 Modelling of personal data views
Simple user data view (as is in most of mobile phones) 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. 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…..

36 Building own data model…
added slot (property/field) inherited slot

37 Building own data structure
“Relative is a kind of friend” Inherited properties Links to other data entities added slot (property/field) inherited slot

38 Building own data structure
Customized data model: new kinds of data new kinds of representation rules and constraints for data etc. association of data with applications added slot (property/field) inherited slot

39 Using generated interface
For described data model forms are generated 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!

40 Access your data quickly and easily…
Possibilities to build flexible, easily customizable data management applications are great. Event data Just click to open Terziyan’s Contact data 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

41 Customizable personal information management environment
Easy-to-use, flexible, customizable data management for users 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 Repositories of ready data-views Enabled collaboration and interoperability Note: Protégé-2000 ontology development and knowledge acquisition tool was used for demonstration

42 OntoCache Ubiquitous Semantic Web Translation
General ontology Ubiquitous Semantic Web Translation Ubiquitous computing seems to penetrate into all human environments. Amount of information resources increases significantly that makes search of appropriate data extremely difficult. This stands even worse for mobile devices which have limited computing resources. Semantic annotation of all such information resources in human environments enhance much the efficiency of their search. Ontocache is a software, capable to process semantically annotated information Web-resources. It provides a local Semantic-based browser of web-resources making their search much easier. Its logic is based on local ontology of the resources the user is interested in. The ontology is used for specification of semantic queries that are sent by software to the external environment. The interface of the browser can combine tree-based navigation with semi-natural queries. Initially some statistically general ontology is set as default in the mobile terminal. However, user can alter it according to his needs (student, doctor, psychologist, etc.). If the local ontology isn’t detailed enough for composition of a final query its deeper parts are downloaded from external stores. Thus, depending on user preferences some parts of local ontology with time die and some extend. Shared ontologies make the queries and resources descriptions be based on common vocabularies. 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

43 OntoCache: benefits Context and preferences-based adaptation Support for semi-natural queries Effective filtering of wide variety of Web-resources Technology that supports future Ubiquitous Semantic Web OntoCache is a tool that conforms with future vision of having all information resources semantically annotated. The benefits it gives correspond to the main promise of Semantic Web technology to provide effective filtering in conditions of information burst. The idea takes into account limited computing resources of mobile devices and assumes adaptation of local ontology to the user preferences. Caching of ontology allows decreasing the data traffic in the form of external parts of ontologies. Semantic data facilitates much more complicated queries than keyword-based ones – semi-natural. Additionally, the behaviour of the navigator can be context-dependent (location, weather, daylight personalization, etc.)

44 Agent-to-Agent communication
Peer-to-Peer Semantic annotation of the local data enables its intelligent processing by software. Ontologies provide interoperability between heterogeneous peers. Phone calls are also possible between mobile terminal agents. They are performed without human participation in order to exchange local information.

45 Agent-to-Agent communication
semantics enables intelligent data processing ontological relations Business define possible Cooking cooperation between domain agents shared ontology Health ensures interoperability Whatever ? Semantic enriching mobile device data allows software agents perform its intelligent processing substituting human. Software agents which had been programmed basing on certain ontology can perform domain-specific data processing. Relations between domain ontologies define possible cooperation patterns between correspondent agents. Shared ontology ensures interoperability between agents that exchange information. annotate problem domains into related ontologies programm software basing on the ontologies semantically enrich data basing on ontologies

50 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. Annotated data (RDF) Ontology of gathered data Web forms and dialogs generated Processing of data by some other semantic-aware applications
