This paper describes our conceptual framework of closed-loop lifecycle information sharing for product-service in the Internet of Things (IoT). The framework is based on the ontology model of product-service and a type of IoT message standard, Open Messagi ...
This paper introduces a query refinement method applied to questions asked by users to a system during a meeting or a conversation that they have with other users. To answer the questions, the proposed method leverages the local context of the conversation ...
Knowledge is getting increasingly more complex. Learners, from Kindergarten to higher education, require powerful tools to connect complex ideas. This paper explores the range of studies that investigated concept maps as learning, metacognitive, collaborat ...
Digital knowledge maps are rich sources of information to track students’ learning. However, making sense of concept maps has been found challenging. Using multiple quantitative and qualitative methods in combination allows triangulating of changes in stud ...
Concept map activities often lack a subsequent revision step that facilitates knowledge integration. This study compares two kinds of concept map critique activities embedded in an evolution unit: Student dyads in one group compared their concept maps agai ...
The Venice Time Machine project aims at building a multidimensional model of Venice and its evolution covering a period of more than 1000 years. Kilometers of archives are currently being digitized, transcribed and indexed setting the base of the largest d ...
With the large-scale adoption of GPS equipped mobile sensing devices, positional data generated by moving objects (e.g., vehicles, people, animals) are being easily collected. Such data are typically modeled as streams of spatio-temporal (x,y,t) points, ca ...
Focus on movement data has increased as a consequence of the larger availability of such data due to current GPS, GSM, RFID, and sensors techniques. In parallel, interest in movement has shifted from raw movement data analysis to more application-oriented ...
Concept maps can be used as generative assessment tools to identify changes in learner’s understanding. However, concept map analysis usually only focuses on the final product. This case study used a talk aloud protocol to study and compare the concept map ...
Concept map analysis usually focuses only on the final product. This case study used a talk aloud protocol to study the concept map construction processes of novices and experts. Three biology experts and three novices (9th/10th grade high school students) ...
