Complexity and Scalability in Semantic Graph Analysis

Semantic approaches offer a more natural way to combine disparate sources of data and to search for complex patterns. However, limitations of common computer hardware architectures can place an upper limit on the scalability of graph stores. Previous data management architectures have been very successful, but trade-offs related to their intended purposes have created built-in limitations. Classic relational databases offer storage efficiency, but performance can suffer as more data sources are added. Denormalized data warehouses improve performance but at a cost of complexity and increased maintenance. New storage paradigms such as Hadoop offer lower cost and higher parallel performance, but their highly partitioned nature limits the type of data that may be analyzed. This talk will present a new in-memory semantic graph database built over a unique multithreaded supercomputer, based on RDF and SPARQL, and describe its performance. Several real-world uses will be described, drawn from life sciences, financial services and cybersecurity.

Semantic Data Modeling: The Key to Re-Usable Data

There is significant industry confusion in understanding the differences between logical, physical, and semantic data modeling. This workshop will provide a clear understanding of the role for semantic data modeling when deploying an enterprise data warehouse. An approach for development of a semantic data model will be described. In addition, we will describe the VIP methodology for realization of a semantic data model using an access layer on top of an enterprise data warehouse with an optimized combination of views, indexes, and physicalization.

  • Learn about the differences between logical, physical, and semantic data models.
  • Learn how use of semantic data modeling can reduce data redundancy in an analytic environment.
  • Learn how to make good design tradeoffs in regard to performance, maintenance, and storage costs in the realization of the access layer aligned to your semantic data model.

Introduction to SDShare

SDShare is a stream based protocol for exposing and consuming data in a standardised way. It uses Atom and RDF as building blocks to allow servers to expose collections of data, and clients to process and update local data stores with copies of the data.

RDF provides a very flexible data model that allows data of any form to be represented. The existing RDF family of standards define how to serialise the model, how to query the model (SPARQL) and how to update the model (SPARQL Update). However, there are no protocols that define how a machine can both expose and consume RDF in a system of interconnected nodes. A classic use case for this requirement is where one RDF server contains a collection of master data and another RDF system wishes to use that data. The master data will change over time. This protocol defines how the master data server can publish the changes to the resources it manages and how a client can consume them to ensure it is in sync.

While the standard uses RDF for interchange, source systems need not support RDF natively, but instead transform data as requested into RDF. This makes SDShare a solution to the general problem of enterprise information integration and compares favorably when compared to data integration via Web Services.

The protocol was original developed as a response to an eGovernment challenge of syndicating asset metadata between government agencies. Since then it has been refined and published as an open standard at SDShare.org. It has also been in use in many government and commercial applications. The main business uses for SDShare include, enterprise search of multiple sources, master data management, data quality management, content classification and unified data merging and querying.

This presentation will describe the technical aspects of the standard and well as provide high level overview of the most common use cases.

Ontology-based data management

The need of effectively managing the data sources of an organization, which are often autonomous, distributed, and heterogeneous, and devising tools for deriving useful information and knowledge from them is widely recognized as one of the challenging issues in modern information systems. Ontology-based data management aims at accessing, using, and maintaining data by means of an ontology, i.e., a conceptual representation of the domain of interest in the underlying information system. This new paradigm provides several interesting features, many of which have been already proved effective in managing complex information systems and addressing the above mentioned challenges. In this talk we first provide an introduction to ontology-based data management, illustrating the main ideas and techniques for using an ontology to access the data layer of an information system, and then discuss several important issues that are still the subject of extensive investigations by the Knowledge Representation and Reasoning community.

Hafslund SESAM -- Semantic Integration in Practice

Sesam is an archive system developed for Hafslund that achieves the often-sought but rarely-achieved goal of automatically enriching metadata by using semantic technologies to extract and integrate business data from business applications. The extracted data is also indexed with a search engine together with the archived documents, allowing true enterprise search.

The system is unusual both for the functionality provided, and for the architecture, which we believe provides a superior approach to information integration.

Measurable Security for the Internet of Things

Business intelligence is moving towards the real-time handling of information, coming from both internal and external business processes. Inclusion of sensor data in automatic process control has been a topic in industry for quite a while, but was mainly limited to closed systems. Trends in collaborative industries like oil & gas show that sensor data might contribute to automatic processes in different domains, fostered by the vision of the Internet of Things.

The presentation will address the challenges of communication across domains, focussing on the challenges of new infrastructures, new ways of communication and new devices. Two main trends are visible: (i) wireless sensors contributing to automated processes and (ii) the move of control into mobile devices. The example of "bring your own device" (BYOD) is used to exemplify the trends of devices accessing processes and information in your enterprise. In the upcoming years not only phones, tablets and computers will demand access, but also sensors and embedded system will deliver and request information. Sensors will contribute to automated processes, and thus require a knowledge management.

Classic threats as insufficient authentication and loss of devices are addressed through an approach of integrating, managing and securing mobile devices. Such a short-sighted approach, as suggested by leading IT companies, is deemed to fail. A paradigm shift in handling security is required, addressing the need for securing information instead of securing infrastructure. The paradigm shift includes the need for measurable security, and addresses a metrics-based approach for a quantitative assessment of both the potential attack scenario and the security measures of the infrastructure.

Our suggested approach is based on the semantic description of both a potential attack scenario, the security-related aspects of my sensors/systems and semantic policies. The outcome is a methodology for measurable security, and provides composable security for sensor systems. The approach is currently applied in the areas of Railway Security and UAV operation through the European Artemis project nSHIELD (http://newSHIELD.eu)

Building applications with Semantic Technologies

Semantic Technologies may seem quite complex in the beginning, but by using existing tools it is possible to assemble useful applications quite easily. In this presentation we will explore how triple stores can manage data for useful applications. The graph properties of triple stores are a benefit for many applications and we will explore how to both use this and visualize data from triple stores. The examples will be practical with several examples related to a planned information hub for sharing crucial logistics information between companies operating on the Norwegian Continental Shelf.

Logical Semantic Warehouse - Developing Your Own Semantic Ecosystem

Gartner has defined the Logical Semantic Warehouse (LSW) as a new data management architecture for analytics combining the strengths of traditional repository warehouses with alternative data management and access strategy. The LSW will form a new best practice by the end of 2015 according to Gartner.

Organizations are reporting faster time to delivery, greater flexibility and an ability to include additional forms of processing such as virtualization and even content analytics in their analytics solutions — all managed by a common semantic layer or engine to deliver the assets to multiple different analytic applications.

Dr. Peter Lawrence from TopQuadrant will describe the evolution of LSW from existing data warehouse and data mart technology practices and the semantic version of LSW, its architecture and benefits.

Semantic Data Analytics for Integrated Energy and Industry Automation Systems

Integration across the layers of the automation pyramid has been a key to increasing transparency and efficiency in both the industry and energy automation domains.

Nowadays, the focus shifts from this intra-domain integration towards a broader inter-domain approach where energy provision and energy consuming production processes are closely linked. Data interoperability is an important enabler for providing an integrated management of the composed system and added value services based on advanced business analytics.

This talk presents our current efforts in using semantic modeling and analytics in this endeavour, and its benefits in efficiency and environmental impact.

Experiences with organisational linked data

Over the last couple of years major government bodies in Norway and Sweden has been demonstrating the value from publshing national company registies as linked open data. Organizational data containing information about management and board members, number of employees, locations and various classifications has been linked to accounting information and to eachother. Over these data various demonstrators have been build. The power and ease of developing demonstrators over a linked data and Semantic Web infrastructure has been demonstrated. An innovation project known as Semicolon has been a key driver for this progress, and we continue to demonstate the value of linked data inside the firewall. In this presentation we will show how we've collaborated and how the agencies have matured and how demonstrators with focus on business intelligence becomes an eye opener.

Can semantic technologies revolutionize administrative ICT?

Being responsible for a big organization’s management system which received low user satisfaction scores even though it had been developed aided by recognized consultants and documented in one of the most advanced tools available I asked one of my co-workers how the system could be made simpler and more user friendly at reasonable costs. Quite quickly he returned with the answer that this would be achievable by using a semantic wiki. It turned out not to be possible to convince the ICT department to explore the idea. However four years later we realized the idea in Skaperhuset.

The presentation outlines how a management system was developed in a Semantic Mediawiki combining semantic technology, competence on "framing and anchoring", the Business Motivation Model and HSEQ competence. The presentation also discusses future applications far beyond management systems.

From Big Data to Smart Data

Companies increasingly are realizing that they have more than a “big data” problem. What they really have is a “Big Metadata” problem, in that the barrier for timely and complex analytics is not necessarily the processing speed or the storage volume, but the fact that valuable metadata is spread across many inconsistent and heterogeneous repositories, or that the insufficient metadata makes complex data analysis time consuming and costly.

Semantic Technologies and RDF data warehousing in particular, have the potential to help with establishing harmony among enterprise metadata and timely insight discovery

How to achieve common semantics on business information/vocabularys

How to combine traditional business terms  from business intelligence in a larger landscape throughout the business. SOA and process management has been ruling the integration, while Business Intelligence has been focusing on data and information. Today we see that companies must combine the information with the processes and hence a common information model is needed. This is a speech about how  some Norwegian companies have tried different approaches to achieve this.

NLP-Driven Ontology Modeling

The Oil Industry will be changing, or will need to change, to make use of all the data that it is gathering now about its fields. While the Oil Industry has always been a major consumer of processing power for seismic, it appears the problems presented for understanding real large fields are forcing a change in how data will need to be processed in the direction of using pattern recognition or artificial intelligence approaches. This is an uncomfortable change for many petroleum engineers whose approach is based on a different sort of modeling.

Ontologies and Natural Language Processing (NLP) can often be seen as two sides of the same coin. NLP-driven Ontology modeling is the processing of using information discovery techniques to drive natural language understanding of unstructured data. As language is modeled, and entities are discovered and relationships between entities understood, Ontology models can be formed.

Ontology-driven Natural Language Processing (NLP) uses the modeled entities and relationships to drive understanding of dialog in interactive systems, provide answers to questions posted to an expert system, and to further refine the same models.
