playence is a provider of intelligent solutions for corporate knowledge management, supporting all types of media, such as text, video, audio, or images. Our mission is to help organizations worldwide reduce the costs associated with managing, integrating, and interlinking knowledge assets from various sources, ensuring availability and access across the organization. Depending on your needs, we offer you different product lines:
The Journal of Web Semantics is an interdisciplinary journal based on research and applications of various subject areas that contribute to the development of a knowledge-intensive and intelligent service Web. These areas include: knowledge technologies, ontology, agents, databases and the semantic grid, obviously disciplines like information retrieval, language technology, human-computer interaction and knowledge discovery are of major relevance as well. All aspects of the Semantic Web development are covered.
"In this section, we will introduce KG by asking some simple but intuitive questions about KG. In fact, we will cover the what, why, and how of the knowledge graph. We will also go through some real-world examples."
"The Open Science (or Open Scholarship) movement has been gaining momentum, especially since the European Commission has committed itself to ensuring open access to all funded research in April 2016. Expensive paywalls used by publishers, restrictive usage policies by scientific literature sources, a lack of consistency in the formatting and data locked away by proprietary software have all had detrimental effects on the dissemination of scientific knowledge."
The Rhizomik initiative is inspired by the rhizome metaphor when working with knowledge from a scientific, technological but also philosophical point of view. This metaphor has accompanied us in our research about knowledge in many different fields, fundamentally Semantic Web, Human-Computer Interaction, Web Science, Complex Systems and Cognitive Science.
The NeuroCommons project seeks to make all scientific research materials - research articles, knowledge bases, research data, physical materials - as available and as usable as they can be. We do this by fostering practices that render information in a form that promotes uniform access by computational agents - sometimes called "interoperability". We want knowledge sources to combine easily and meaningfully, enabling semantically precise queries that span multiple information sources.
YAGO2 is a huge semantic knowledge base, derived from Wikipedia, WordNet and GeoNames. Currently, YAGO2 has knowledge of more than 10 million entities (like persons, organizations, cities, etc.) and contains more than 120 million facts about these entities.
the complete (non-proprietary) content of the Cyc knowledge base is being made available to the research community (for research-only purposes) under a ResearchCyc license. Yes, Cyc, the world's largest and most complete general knowledge base and commonsense reasoning engine, is at your disposal!
"The term "Knowledge Graph" has recently become mainstream as information giants like Google, Facebook, Yahoo, Microsoft, have announced their move from traditional search and data management to "Knowledge Graphs". See here, here and here."
Flora-2 is an advanced object-oriented knowledge representation and reasoning system. It is a dialect of F-logic with numerous extensions, including meta-programming in the style of HiLog, logical updates in the style of Transaction Logic, and defeasible reasoning. Applications include intelligent agents, Semantic Web, knowledge-bases networking, ontology management, integration of information, security policy analysis, and more.
"YAGO2s is a huge semantic knowledge base, derived from Wikipedia WordNet and GeoNames. Currently, YAGO2s has knowledge of more than 10 million entities (like persons, organizations, cities, etc.) and contains more than 120 million facts about these entities."
"MusicGraph is the world's first knowledge engine for music. It contains over a billion facts that have been organized into a rich music ontology, which includes acoustical and lyrical features, detailed artist, album and song information, as well hundreds of other data points related user preferences."
Knowledge Organization Systems/Services (KOS) model the underlying semantic structure of a domain. Embodied as Web-based services, they can facilitate resource discovery and retrieval. They act as semantic road maps and make possible a common orientation by indexers and future users (whether human or machine).
OntoWiki
is a tool providing support for agile, distributed knowledge engineering scenarios.
OntoWiki facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode for editing RDF content, similar to WYSIWIG for text documents.
