The integration of the Information and Communication Technologies (ICT) has changed significantly the field of education. Due to the adoption of new technologies, e-learning has been emerged and developed. As a result, distance learning has transformed and new possibilities have appeared. It is remarkable that distance learning became and considered as a scout of the new era in education and contributed to the quality of education. Supporting tutors by advanced learning technologies in distance education is a significant contribution for their effective role in organizational, social and educational context. The Learning Activity Management System (LAMS) is a new proposal to the learning design standard. In this paper, we propose the LAMS exploitation at the Hellenic Open University (HOU) and illustrate a guide to design and develop a sequence of learning activities on “Preparing and producing assignment”. The preparation of the assignments by students is the primary mode of the comprehension of educational materials and an important dimension of teaching students in distance education context, where they are the main responsible for their learning. This proposal highlights the advantages, requirements and constraints concerning the development of learning sequences specifically designed by tutors themselves. They follow the principles of adult learning and development of distance education material, oriented to different educational goals and individual needs of their learners.

From Research to Applications: What Can We Extract with Social Media Sensing?Yiannis Kompatsiaris
SIGMAP22 Keynote Presentation:
Social media have transformed the Web into an interactive sharing platform where users upload data and media, comment on, and share this content within their social circles. The large-scale availability of user-generated content in social media platforms has opened up new possibilities for studying and understanding real-world phenomena, trends and events. Social media and websites provide an access to public opinions on certain aspects and therefore play an important role in getting insights on targeted audiences. The objective of this talk is to provide an overview of social media mining, including key aspects such as data collection, multimodal analysis and visualization. Challenges, such as fighting misinformation, will be presented together with applications, results and demonstrations from multiple areas including: news, environment, security, interior and urban design.
Social media mining for sensing and responding to real-world trends and eventsYiannis Kompatsiaris
Social media have transformed the Web into an interactive sharing platform where users upload data and media, comment on, and share this content within their social circles. The large-scale availability of user-generated content in social media platforms has opened up new possibilities for studying and understanding real-world phenomena, trends and events. The objective of this talk is to provide an overview of social media mining, which offers a unique opportunity to to discover, collect, and extract relevant information in order to provide useful insights. It will include key challenges and issues, such as fighting misinformation, data collection, analysis and visualization components, applications, results and demos from multiple areas ranging from news to environmental and security ones.
Visual Information Analysis for Crisis and Natural Disasters Management and R...Yiannis Kompatsiaris
Invited talk at the Ninth International Conference on Image Processing Theory, Tools and Applications IPTA 2019 (http://www.ipta-conference.com/ipta19/)
Crises and natural disasters are unwelcome, but also unavoidable features of modern society, affecting more communities than ever. Visual information analysis plays an important role in efficient pre-event (e.g. risk modeling), during the event (response) and post-event (recovery) emergency situation management. This talk will describe the potential role of visual information sources including satellite images, surveillance and traffic cameras, social multimedia and aerial video in applications such as floods, fires, and oil spills. Multimodal and fusion techniques will be presented combining satellite and social data and how deep neural networks can be applied in this domain. The talks will include demos and results from the relevant BeAware and EOPEN projects and from our participation in the 2018 Multimedia Satellite Task of the MediaEval Benchmarking Initiative.
This is a presentation on Sensor Based Ambient Assisted Living architecture and approaches developed by the Multimedia Knowledge and Social Media Analytics Lab of CERTH-ITI. It includes sensors used for monitoring Activities of Daily Living of elders and persons with mild Dementia at home. Visual and sensor data analytics are combined with formal representations (ontology), fusion, reasoning techniques and visualizations in order to provide an objective view of everyday activities. Example projects and pilots are included. Clinical assessment show improvement in cognitive abilities of participants.
The pervasive use of Online Social Networks (OSN) for networking, communication and search in tandem with the ubiquitous availability of smartphones, which enables real-time multimedia capturing and sharing, have led to massive amounts of user-generated content and activities being amassed online, and made publicly available for analysis and mining. Each content item is associated with an abundance of metadata and related information such as location, tags, comments, favorites and mood indicators, access logs, and so on. At the same time, all this information is implicitly or explicitly interconnected based on various properties such as social links among users, groups, communities, and sharing patterns. These properties transform social media into data sources of an extremely dynamic nature that reflect topics of interests, events, and the evolution of community opinion and focus. Social media processing offers a unique opportunity to structure and extract information and to benefit multiple areas ranging from new media experiences to psychology and marketing. The objective of this talk is to provide an overview of the current research in emerging topics related to applications where social media can act as sensors of real-life phenomena and case studies that reveal valuable insights. After discussing challenges and presenting a generic conceptual architecture, there will be a focus on efficient processing and indexing algorithms that can handle massive amounts of content with application to graph-based event detection and summarization in social media streams.
Social Media Verification Challenges, Approaches and ApplicationsYiannis Kompatsiaris
As grassroots and social media-based journalism becomes more widespread, the need to verify information coming from such channels becomes imperative. The objective of this talk is to explore the challenges involved in social media computational verification to automatically classify unreliable media content as fake or real. After presenting a generic conceptual architecture, there will be a focus on tweets around big events linking to images (fake or real) of which the reliability could be verified by independent online sources. The REVEALr platform will be demonstrated, a scalable and efficient content-based media crawling and indexing framework featuring a novel and resilient near-duplicate detection approach and intelligent content- and context-based aggregation capabilities (e.g. clustering, named entity extraction)

The DemaWare Service-Oriented AAL Platform for People with DementiaYiannis Kompatsiaris
This work presents DemaWare, an Ambient Intelligence platform that targets Ambient Assisted Living for people with Dementia. DemaWare seamlessly integrates diverse hardware (wearable and ambient sensors), as well as soft- ware components (semantic interpretation, reasoning), involved in such context. It also enables both online and offline processes, including sensor analysis and storage of context semantics in a Knowledge Base. Consequently, it orchestrates semantic interpretation which incorporated defeasible logics for uncertainty handling. Overall, the underlying functionality aids clinicians and carers to timely assess and diagnose patients in the context of lab trials, homes or nursing homes.

Social Data and Multimedia Analytics for News and Events ApplicationsYiannis Kompatsiaris
The keynote discusses a framework enabling real-time multimedia indexing and search across multiple social media sources. It places particular emphasis on the real-time, social and contextual nature of content and information consumption in order to integrate topic and event detection, mining, search and retrieval, based on aggregation and indexing of shared user-generated multimedia content. User-friendly applications for the News and Events domains have been developed based on these approaches, incorporating novel user-centric media visualisation and browsing methods. The research and development is part of the FP7 EU project SocialSensor.

Social media mining and multimedia analysis research and applicationsYiannis Kompatsiaris
In this talk, research and applications in social media mining and multimedia analysis are going to be presented. Social media sharing websites host billions of images and videos, which have been annotated and shared among friends, or published in groups that cover a specific topic of interest. The fact that users annotate and comment on the content in the form of tags, ratings, preferences and so on, and that these activities are performed on a daily basis, gives such social media data source an extremely dynamic nature that reflects topics of interests, events and the evolution of community opinion and focus.
The talk will present research challenges and activities and will focus on multi-modal graph-based community detection methods for social media mining, concept and event detection. Clusttour, a mobile and web application integrating research results with appropriate interface design will be demonstrated as a relevant use case. The talk will also include approaches for object/region classifiers learned using the self-training paradigm with loosely annotated training samples automatically selected from social media.

37. Diadohokinetic (DDK) Test
DDK tests are used by speech-language pathologists for assessment of
motor speech impairments, e.g. dysarthria
Quick and accurate production of rapid, alternating sound tokens
involving different parts of mouse, e.g. “puh-tuk-kuh—puh-tuh-kuh—
…”
Usually measurements are done manually and include the DDK rate statistics
Our hypothesis and research direction:
The DDK test may challenge both motor and cognitive control over speech
production
Motor and cognitive faults deteriorate the temporal regularity of the audio
signal normally expected in this type of utterances
We can develop a regularity measure of the DDK performance
Is the DDK regularity useful in distinguishing between Control/MCI/AD
groups?

73. Improve My City
App for Citizens Reporting Issues in Municipalities – Regions
Currently used by Thermi Municipality, Thessaloniki, Greece
http://mklab.iti.gr/imc/
74. Why do we need an app for that?
• Municipalities and Regions cover large areas
– Issues collection, prioritization and addressing is time
consuming and costly
– Regional authorities want to listen (or at least show they are
listening) what their citizens are saying
• Citizens want to participate
– Social Networks create new culture and technical possibilities
– They are interested in their everyday problems (especially if
they receive timely feedback)
• Citizens can become a cost and time efficient real-time
sensor of issues and the best source for solution ideas
and prioritization (Collective Intelligence)
