Deep Learning and Cultural Heritage: The CEPROQHA Project Case Study
2019
Cultural heritage takes an important part of the history of humankind as it is one of the most powerful tools for the transfer and preservation of moral identity. As a result, these cultural assets are considered highly valuable and sometimes priceless. Digital technologies provided multiple tools that address challenges related to the promotion and information access in the cultural context. However, the large data collections of cultural information have more potential to add value and address current challenges in this context with the recent progress in artificial intelligence (AI) with deep learning and data mining tools. Through the present paper, we investigate several approaches tha…
Social Media Data in an Augmented Reality System for Situation Awareness Support in Emergency Control Rooms
2021
AbstractDuring crisis situations, emergency operators require fast information access to achieve situation awareness and make the best possible decisions. Augmented reality could be used to visualize the wealth of user-generated content available on social media and enable context-adaptive functions for emergency operators. Although emergency operators agree that social media analytics will be important for their future work, it poses a challenge to filter and visualize large amounts of social media data. We conducted a goal-directed task analysis to identify the situation awareness requirements of emergency operators. By collecting tweets during two storms in Germany we evaluated the usefu…
Methods for defining user groups and user-adjusted information structures
1999
A common problem in the design of information systems is how to structure the information in a way that is most useful to different groups of users. This paper describes some statistical methods for revealing the structure inherent in empirical data elicited from users. It is illustrated by the application of these methods to the design of some web pages giving information about the Universitat de Valencia. Three potential user groups were identified, administrative staff, teaching staff and students. The first analysis demonstrated that users within these three groups assign relatively homogeneous structures, but that the structures assigned by the three groups are not the same, and also, …
A Latent Class Analysis of Spanish Travelers’ Mobile Internet Usage in Travel Planning and Execution
2014
A study of 476 Spanish travelers found mixed interest and use for the many travel-related mobile internet services that are involved in planning and executing a trip. The findings indicate that these Spanish respondents can be classified into four segments based on the timing of using mobile apps for over a dozen activities involved in travel planning and execution: Savvies, Planners, Opportunists, and Low-techs. Each segment exhibits distinct patterns of mobile internet services usage. Savvies tend to be heavy mobile device users both before and during their trip, while Planners make heavy use of mobile devices in advance of but not during their trip. The Opportunists show a pattern oppos…
