Article
In a society with a growing population of elders, providing efficient and cost-effective long-term care has become central to reducing the economic and societal impact of this demographic shift. Part of the solution to improving the well-being of the elderly at home are smart homes. We examine the role of smart homes in monitoring the activities of...

One of the biggest concerns in Ambient Assisted Living (AAL) proposals is helping the population of elderly people in order to maintain their independence and autonomy. A relevant task done by AAL is the automatic inference of a person’s activities of daily life (ADL) from data streams recorded by sensors deployed on an active environment. This wor...
Conference Paper
News content usually refers to specific facts, people or situations. Understanding the whole relationships and context about the actual text may require the user to manually connect, search and filter other sources, with a considerable effort. This work considers the use of deep learning techniques to analyze the news content to automatically build...
Conference Paper
The design of highly scalable architectures based on the Hadoop ecosystem is highly complex due to the wide and dynamic portfolio of available tools. The feasible solution generator for big data problems, BiDArch, allows to automatically establish a feasible architecture from the characterization of a problem in terms of tools features. This proces...
Conference Paper
Active Aging is a proposal that aims to improve life quality, as a person grows old. One of the main use cases of this concept is the application of products and services based on technology; this approach, known as Ambient Assisted Living (AAL). An important activity performed by AAL is the discovery of the user’s activities of daily life (ADL) em...
Conference Paper
For Smart Environments used for elder care, learning the inhabitant’s behavior patterns is fundamental to detect changes since these can signal health deterioration. A precise model needs to consider variations implied by the fact that human behavior has an stochastic nature and is affected by context conditions. In this paper, we model behavior pa...
Data
This open dataset contains real-life sensor data of a person living in a smart home for 28 days. A deep sensing approach was used with over 200 variables measured. These include all doors (rooms, gabinets, fridge) state, light states, temperature, Co2 levels, noise levels, weather, appliances (oven, stove, tv, coffee maker) state. 8 daily living...
Conference Paper
Research on context management and activity recognition in smart environments is essential in the development of innovative well adapted services. This paper presents two main contributions. First, we present ContextAct@A4H, a new real-life dataset of daily living activities with rich context data (This research is supported by the Amiqual4Home Inn...
Article
Ambient Assisted Living, smart environments and technology used for elder care, increases independent living time and cuts long-term care costs. An important requirement for these systems is detecting and informing about abnormal behavior in users' routines. Still, routines may change when certain context conditions hold, which does not mean these...
Conference Paper
Campuses of universities and companies are examples of physical resources shared by a community, which usually interact with these resources in a very limited way because the lack of relevant and timely integrated information. The information provided by traditional campus information systems does not contribute to an effective user experience, doe...
Article
Human behavior learning plays an important role in ambient assisted living since it enables service personalization. Current work in human behavior learning do not consider the context under which a behavior occurs, which hides some behaviors that are frequent only under certain conditions. In this work, we present the notion of a contextualized be...
Conference Paper
The value in the vast amount of linked data and open data produced during the last decade is widely recognized and being exploited by different initiatives. However, a remaining challenge is to integrate government information with semi-structured data in sources relevant to citizens, who have become skeptical of official versions and more interest...

We detail the solution of team uniandes1 to the ESWC 2014 Linked Open Data-enabled Recommender Systems Challenge Task 1 (rating prediction on a cold start situation). Ín these situations, there are few ratings per item and user and thus collaborative filtering techniques may not be suitable. Ín order to be able to use a content-based solution, link...
Article
Most of the work in the affective computing field focuses on the recognition of the six basic emotions (sadness, happiness, anger, surprise, disgust and fear). However, when doing academic activities like reading, researching, doing homework or others, these basic emotions are not reported as frequently as others such as interest, confusion and bor...
Conference Paper
BirdFinder is a bird search engine that applies concepts of information retrieval and Web 2.0 to allow nonexpert users to access information using text and audio search mechanisms. It integrates audio, images and identification characteristics related to the ornithology domain. Content is stored in a highly scalable NoSQL repository. The main contr...
Conference Paper
Unified Financial Portfolio is a financial application that applies concepts of information retrieval and Web 2.0 to provide a better understanding of the market trends taking into account the users information needs. It integrates and retrieves non-structured content related to the financial domain, from social networks, Stock Exchange and newspap...
Conference Paper
Application developers require cloud solutions that offer a highly scalable and secure development environment. Some Platform-as-a-Service (PaaS) solutions fail to meet the security requirements of developers, administrators, and final users in a satisfactory and flexible manner. While some providers do offer secure cloud solutions, users are oblig...
Chapter
The Web 2.0 evolution has renovated the way in which the producers and consumers of information interact. Online newspapers have allowed readers to express their views of the news being read, by publishing a comment. Recognizing that the aggregation of comments can produce valuable information about the topic being commented is the main contributio...
Conference Paper
Recently, there has been a big movement towards converging engineering education and practice by means of defining clear and complete program goals. In this context, a large scale of educational institutions face challenges on how to specify the desired educational goals for a specific discipline and on how to instantiate and evaluate their program...
Conference Paper
MentalWatch is a medical search engine that applies concepts from information retrieval and Web 2.0 to enable patients and doctors to better understand mental illnesses. It puts together scientific articles, news, blog posts and other kinds of contents related to mental health from several Web sources. The main contribution of this work is a softwa...

The specification for an information system can be clear from the beginning: it must acquire, display, query and modify data, using a database. The main issue is to decide which information to manage. In the case originating this work, information was always evolving, even up to the end of the project. This implies the construction of a new system...

La especificacion de un sistema de informacion puede estar clara desde el principio: debe adquirir, desplegar, consultar y modificar datos, usando una base de datos. El asunto es decidir cual informacion manejar. En el caso que origina este trabajo, la informacion evoluciona permanentemente, incluso hasta el final del proyecto. Esto implica la cons...
Conference Paper
Currently, the grid applications have to assume the possible inconsistency of received content generated by another grid applications or components. Somehow, it limits the applications autonomy, because they would need strong coupling concerning the information exchanging so that they can cooperate between them. The strategy proposed to solve this...

In this project, we explored how daily routines change based on context, how to model routines so that the context in which they are relevant is considered and how to automatically learn routines and their contextual descriptors from sensor data using streaming data mining. A routine considers both the start time of an activity and the sequence of activities.
