The paper proposes and extensively evaluates a novel probabilistic and knowledge-driven framework for event representation and recognition, combining different visual sensors (video camera, color-depth and wearable video camera).

Sensorizon wins in Venture Cup regional final

We have some pretty exciting news on the exploitation field!
Sensorizon a Dem@Care business case - a system for assisting people with dementia‬ and personnel in Nursing Homes - won the regional final in the Venture Cup business plan competition in Sweden, in the category "Life Science & Technology”. 50 business cases competed in 4 categories. Apart from the win itself and a little prize money, this gives very valuable contacts for funding further commercial activities.

Sensorizon aims to be a significant European provider of clinical assessment services using mainstream ICT. Our vision is to have a world where both staff members and residents of nursing homes are not stressed, and our mission is to provide an ICT tool to improve the quality of care significantly in Nursing Homes. 

Sensorizon is an ambient intelligence system to be used in Nursing Homes to measure patterns of behavioral and psychological symptoms of dementia. The staff members in nursing homes (clinicians and caregivers) frequently do not fully understand the behavioral changes of people with dementia a fact that makes it very hard to do clinical assessments and to plan better clinical interventions. The system relies on ambient and wearable sensors for observing people with dementia and performs automated analysis to assess their current cognitive and emotional state.

The information from Sensorizon helps the staff members in maintaining a comprehensive view of the changes in behavior and mood and the current health status of the person with dementia. Sensorizon will have positive impacts for both the nursing home, the staff members and people with dementia, by improving care planning and the quality of care in nursing homes.

Winning the Venture Cup Regional Final allows us to boost our business and focus on marketing planning, product launching and customer acquisition. As region winners we also have then the chance to make it to the Sweden final, which takes place in Gothenburg, June 9, 2016. 

Dem@Care videos

One of the key objectives of a research project like Dem@Care is to have an impact on society and its development. But as much of this research is published in specialized international academic journals it is read by only a limited number of people. Online video sharing technologies offer promising new ways for disseminating project results to wider audiences and stakeholders making the latest research and development accessible and easier to share. Using video as a means of disseminating research allows knowledge and ideas to be presented in an intriguing way. Video opens up a new window to the real lives and experiences of people in a format that is credible, authentic, and transparent and in tune with the 21st century. To capitalize upon all these benefits that online video provides the Dem@Care consortium has decided to partner with a video production company to deliver 4 distinct videos. 

A short video animation clip to serve a video promotion of the project and present Dem@Care in a simple, engaging, visually effective and understandable way:

A video about @Lab pilot to demonstrate how Dem@Care can help in the early diagnosis of people with dementia:

A video about @Home pilot to communicate the potential of the use of ICTs and innovative analytics for dementia care from the Dem@Care perspective:

An overall project video to present the context and all the work that has been accomplished:

In the last years, a substantial body of work has focused on the development of cognitive approaches leveraging on a symbolic model representation of the objects belonging to a scene and their relations. Specifically in the domains of Video Surveillance and Ambient Intelligence, recent advances in image, multimedia and video analysis, as well as in object detection and tracking, activity and gesture recognition have highlighted the need to move away from the traditional pattern matching and statistical approaches. Hybrid approaches that couple mining, learning and statistical reasoning with knowledge-driven solutions have emerged that support the development of more flexible, meaningful and robust solutions for improving the analytics aspects. Under this paradigm, Semantic Web technologies have attracted growing interest, bringing to the table the ability to formally capture intended semantics and to support automated reasoning, integration, management and sharing of information. Ontologies provide the means for formally capturing domain information, whereas the underpinning semantics formalise context-aware interpretation services that enable the effective coupling of statistical and logic-based reasoning, making available new forms of business intelligence and video analytics. However, the potential of Semantic Web technologies in addressing key requirements is yet to be fully explored: temporal reasoning, scalability, uncertainty handling, reasoning with noisy and missing information, as well as the theoretical aspects that underpin the combination of Semantic Web technologies with other fields of research, such as open and closed-world assumption, impose new challenges.

The workshop aims to favour the meeting of the Semantic Web, video and image analysis scholars and practitioners for facilitating the adoption of Semantic Web technologies in the domains of Video Surveillance and Ambient Intelligence. With this workshop we want to pave the way towards the proposition of novel hybrid approaches where results produced by traditional bottom-up low-level feature-based vision algorithms are fused with top-down approaches based on Semantic Web technologies.


We encourage original papers from scholars and practitioners aiming at defining, developing and demonstrating use of Semantic Web and knowledge-driven technologies addressing the, but not limited to, following research issues:

- Object detection and tracking;

- Event modelling and detection;

- Ontology-based recognition of activities, actions and gestures;

- Context-aware behaviour analysis;

- Hybrid frameworks for activity detection;

- People tracking and counting in crowd environment;

- Trajectories analysis and retrieval;

- Semantically-enriched situation awareness in JDL;

- Uncertainty in ontology-based systems for video analysis;

- Activity recognition under uncertainty, noise and incomplete data 

- Ontology design patterns for video surveillance and AmI;

- Description Logics and abductive reasoning for video surveillance and AmI;

- Combination of ontologies and rules for video and image analysis;

- Rule-based engine performance evaluation on video analysis datasets;

- SPARQL and rule engines for Video Analytics;

- RDF stream reasoning and video analysis;

- Coupling of Semantic Complex Event Processing with Machine Learning for event detection;


We seek full technical research papers with a length of up to 12 pages. All papers must represent original and unpublished work that is not currently under review. Papers will be evaluated according to their significance, originality, technical content, style, clarity, and relevance to the workshop. At least one author of each accepted paper is expected to attend the workshop (workshop attendees must pay the ISWC workshop registration fee as well as the conference registration fee). Submissions must adhere to the Springer LNCS format and be made through the EasyChair conference system (link will be available soon).

Accepted papers will be included in the workshop proceedings and will be published on the workshop web page.

A selection of best papers will be published in a special issue on Journal of Ambient Intelligence and Humanized Computing (Springer).
