 Central aim of organisation
Intelligent management of multimedia and text

 Briefly describe your organisation
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:

playence prose: Textual Semantic Search Engine
playence prose is a semantically enhanced search engine for annotated textual resources, allowing natural language and conceptual search.

playence media: Corporate Multimedia Management
playence media provides intelligent multimedia management including: automatic semantic annotation, interlinking, search and browsing for the corporate setting. All within a single piece of software that is affordable and easy to manage.

playence crowd: Crowd Sourcing Multimedia Annotation for Video Advertising
The crowd sourcing solution is designed for large amounts of user-generated multimedia. playence uses its technology combined with human computation via casual, social games to create video descriptions. This enables search and contextual video advertising.

 RTD Experience
The next generation Web should not be based on the false assumption that text is predominant [...] The Web is a multimedia environment, which makes for complex semantics. Tim Berners-Lee et al. A Framework for Web Science in: Foundations and Trends in Web Science, Vol. 1, No 1, 2006, pp. 1-130.

Innovation is at the core of our daily business. Playing with new technology and putting new ideas to work is our passion. We invest a lot of time and resources exploring new paths and developing ground breaking technology later materializing as features in our products.

Here is a very brief overview of research areas we are interested in and technologies we are playing with to build innovative and ground-breaking products for you.
Semantic search

The killer app of semantic technology and knowledge management in general is still intelligent search that understands the users query and the information. Semantic search is therefore one of our core interests. We are working with faceted search and filtering for unstructured sources; probabilistic, linguistic, and semantic query expansion; collaborative and social search and many more.
Semantic navigation and visualization of knowledge

Exploiting ontologies for the navigation of networks of information has the potential to fundamentally improve efficiency and user experience. Similary, there are completely novel and innovative ways of visualizing knowledge.
Semantic annotation of text and multimedia

The enrichment of data with semantic descriptions is another core objective of playence. We are playing with automatic and semi-automatic methods for the annotation of text, video, audio, and images. We apply video analysis, speech extraction, game-based mathods and many more to find innovation solutions for the knowledge acquisition bottleneck.
Linked Open Data

The Linked Open Data movement has gained a lot of momentum recently aiming at publishing datasets using RDF. We are looking into exploiting this vast amounts of linked data to enrich content and improve search.
