Siemens and metaphacts showcase Enterprise Knowledge Graphs on Amazon Neptune

AWS re:Invent LogoNovember 29, 2017 - Siemens and metaphacts are among the first Amazon Neptune users and show several use cases for enterprise knowledge graphs using the new service and metaphactory. At AWS re:Invent, Amazon Web Services (AWS) announced Amazon Neptune, a new fully managed graph database service that makes it easy to build and run applications that work with highly connected datasets.

In a joint presentation on Friday Dec 1, Siemens and metaphacts will provide details on how they use Amazon Neptune, standalone graph stores, and the metaphactory platform to drive use cases for enterprise knowledge graphs. Leveraging this combined solution, Siemens powers an intelligent knowledge hub combining structured and unstructured data from different sources and business units in a unified data space. This knowledge hub can also be used as a smart knowledge factory generating new knowledge.

"We are looking forward to investigate Amazon Neptune in depth and we are glad to have a partner in metaphacts which understands our data management needs and has supported us in driving knowledge graph use cases for our business and for our customers", says Thomas Hubauer, Portfolio Project Manager for Knowledge Graph & Semantics at Siemens Corporate Technology.

DATAVERSITY features Onboarding Enterprise Knowledge Graphs with metaphactory

DATAVERSITY LogoOctober 26, 2017 - In the latest article discussing the adoption of enterprise knowledge graphs, Jennifer Zaino, a DATAVERSITY® contributor, provides a detailed account of metaphacts' position in the semantic space and its latest product developments. In her article, Zaino tackles the role knowledge graphs can have in enabling intelligent applications, but also points to the difficulties enterprises face in adopting and implementing these technologies. This is where metaphacts with its end-to-end platform for enterprise knowledge graphs, metaphactory, comes in -- it caters not only to developers and IT experts but also to end users, and thus lowers the barrier to entry. In this context, Zaino points readers to metaphactory's ability to query data graphs using natural language queries, visual query contructions, faceted exploration and even an Amazon Alexa voice interface.

metaphacts contributes new dataset to QALD2017 challenge

DIESEL & HOBBIT Logos May 30, 2017 - The three DIESEL project partners – metaphacts, Zazuko and the University of Leipzig – teamed up with the HOBBIT project to provide a new dataset for the QALD7 challenge, which is taking place at the Extended Semantic Web Conference 2017. The key challenge for QALD7 – Question Answering over Linked Data – is to translate a user's information needs such that they can be evaluated and answered using standard Semantic Web query processing and inferencing techniques.

The dataset created by the partners serves as the 4th task within the QALD7 challenge. For this task, Wikidata, a public data source, is used as a target repository. The teams taking part in the challenge use Wikidata to answer 100 cross-domain factual questions. The collaboration between the DIESEL and HOBBIT project partners resulted in the creation of the metadata, the set of answers available for each question, as well as SPARQL queries executable over the Wikidata query service. The Docker image holding an installation of the Blazegraph Wikidata query service used for QALD7 can be downloaded here »

Geomarketing driven by Knowledge Graphs - metaphacts at CeBIT 2017

CeBIT 2017 March 15, 2017 - As a member of the GEISER consortium, metaphacts will be exhibiting and showcasing its solution for data-driven geomarketing at CeBiT 2017, held in Hannover, Germany on March 20-24.

As part of the GEISER project and in collaboration with YellowMap, the Frauenhofer Institute for Intelligent Analysis and Information Systems and the University of Leipzig, metaphacts has developed an innovative system where geospatial data is used as raw material for intelligent, location-based services. The system delivers great promise for supporting small and medium-sized businesses and retailers in linking sensor data with Social Media data, Open Data, forums, websites and internal customer data, so as to improve their advertising and marketing strategies.

A concrete use case where Twitter data is abstracted and contextualized through the integration with the Wikidata Knowledge graph, so as to enable businesses to formulate precise information needs and conduct accurate queries, will be showcased at the German Federal Ministry of Economic Affairs and Energy booth at CeBIT. In this particular use case, small and medium-sized businesses are able to identify the events taking place in a given region and during a particular timeframe, and, thus, can create targeted advertising campaigns for these events. To learn more about data-driven geomarketing please visit our use case page »

To learn more about metaphacts and our solutions, visit us at CeBIT at booth C40 in hall 6! We look forward to seeing you there! To schedule a meeting during the event, please send us an email at This email address is being protected from spambots. You need JavaScript enabled to view it.
