Zhang J, Calvo R, Shephard R, et al., 2007, Surveillance cattle diseases using embedded application systems, WSEAS Transactions on Information Science and Applications, Vol: 4, Pages: 1069-1074, ISSN: 1790-0832
Veterinary disease surveillance systems are rapidly expanding and developing. A key factor for success of a surveillance system is the ease of data capture. Real-time collection of observations of diseased cattle is difficult because observations occur in the field. This paper presents a mobile embedded application system for reporting cattle disease observations to a veterinary surveillance system in real-time. The mobile system includes an artificial intelligence system and supports data extraction via a user-friendly interface. This allows users to investigate and report cattle disease in the field and is designed to deliver benefits to producers, government surveillance systems and to the cattle industry.
Calvo RA, Carroll NL, Ellis RA, 2007, Curriculum central: A portal for the academic enterprise, International Journal of Continuing Engineering Education and Life-Long Learning, Vol: 17, Pages: 43-56, ISSN: 1560-4624
This paper discusses the design, development and use of a portal system for the administration and integration of teaching activities to improve their effectiveness and coherence. The system provides a knowledge repository of syllabus and instructional design of courses in a university functionality that enables staff to perform administrative activities online a collaboration environment supporting the knowledge repository. The three types of functionality are integrated to benefit key stakeholders: students, who can benefit from a better understanding of the relationships between courses; teachers, who are able to see a reduction in their administration activities; and administrators, who can use the system as a reporting tool.

Adeva JJG, Carroll NL, Calvo RA, 2006, Applying plagiarism detection to engineering education, Pages: 722-731
We describe a novel plagiarism detection system and its integration with an e-portfolio used in first year engineering teaching. The tool addresses an important issue arising from the decreasing barriers to information access. Academics know that information can support valuable learning experiences, but these experiences are diminished when students plagiarise by copying assignments and getting credit for work they have not done. While it is possible for academics to develop project-based activities to make it harder for students to plagiarise work from outside sources, some students will still copy work done by others within the same class, which can be especially difficult to detect within large cohorts. According to student feedback received while assessing an e-portfolio activity, we found that students were also concerned about plagiarism, and that they modify their approaches to learning based on this concern. We developed a plagiarism detection tool called Beagle, which uses an internal method (also known as collusion): whenever a student submits an assignment to the e-portfolio system, it is compared to those previously submitted by other students. Beagle measures the statistical similarity between students' work using text mining methods. When a specific similarity threshold is reached, the work can be flagged as possible plagiarism or the system can automatically warn the student and request that they resubmit their work. In this paper we present the design of the system, a performance evaluation in terms of accuracy and execution time, and a description of its application integration capabilities through web services. © 2006 IEEE.

Turani A, Calvo RA, 2006, Beehive: A software application for synchronous collaborative learning, Campus-Wide Information Systems, Vol: 23, Pages: 196-209, ISSN: 1065-0741
Purpose - The purpose of this paper is to describe Beehive, a new web application framework for designing and supporting synchronous collaborative learning. Design/methodology/approach - Our web engineering approach integrates educational design expertise into a technology for building tools for collaborative learning activities. Beehive simplifies the development of the collaboration tools required to implement proven educational design strategies. The methodology consists of a framework model that has three abstraction layers: pedagogical techniques, patterns, and computer supported collaborative learning components. Findings - Building eLearning systems that are informed by the educational research in design patterns, can lead to a better, richer and more flexible, infrastructure. Beehive's design enables teachers to design and use synchronous collaborative learning activities, either by using well tested research-based learning designs or by creating their own. Research limitations/implications - The system will need to be used by a large number of teachers and learners before evaluation and usability tests are possible. Originality/value - The paper presents an integrated solution application that enables teachers and students to design and carry out synchronous collaborative learning activities in a very simple manner. © Emerald Group Publishing Limited.

Calvo RA, Lee JM, Li X, 2004, Managing content with automatic document classification, Journal of Digital Information, Vol: 5, ISSN: 1368-7506
News articles and Web directories represent some of the most popular and commonly accessed content on the Web. Information designers normally define categories that model these knowledge domains (i.e. news topics or Web categories) and domain experts assign documents to these categories. The paper describes how machine learning and automatic document classification techniques can be used for managing large numbers of news articles, or Web page descriptions, lightening the load on domain experts. The paper uses two datasets, one with with more than 800,000 Reuters news stories and another with over 41,000 Web sites, and classifies them using a Naïve Bayes algorithm, into predefined categories. We discuss the different parameters and design decisions that normally appear when building automatic classifiers, including, stemming, stop-words, thresholding, amount of data and approaches for improving performance using the structure in XML documents. The methodology developed would enable Web based applications or workflow systems to manage information more efficiently, i.e. by assigning documents to topics automatically or assisting humans in the process of doing so.
Ellis RA, Calvo RA, 2004, Learning Through Discussions in Blended Environments, Educational Media International, Vol: 41, Pages: 263-274, ISSN: 0952-3987
This paper reports research into the student experience of learning through discussions in a blended environment. Third year engineering students studying e-commerce engaged in both face-to-face discussions and online asynchronous discussions as key aspects of their learning experience. Adopting a quantitative methodology, questionnaires were completed by students at the end of their learning experience. The results suggest qualitatively different experiences of learning through discussions. The results show that students who have a deep understanding of how the discussions are related to their learning outcomes tend to approach the discussions in more meaningful ways. In the face-to-face context, their approach emphasizes learning through the experience of others and, in the online environment, their approach emphasizes reflecting on the problems discussed from a variety of perspective. © 2004, Taylor & Francis Group, LLC.
Ellis RA, Calvo R, Levy D, et al., 2004, Learning through discussions, Higher Education Research and Development, Vol: 23, Pages: 73-93, ISSN: 0729-4360
Students studying a third-year e-commerce subject experienced face-to-face and online discussions as an important part of their learning experience. The quality of the students' experiences of learning through those discussions is investigated in this study. This study uses qualitative approaches to investigate the variation in the students' understanding of what they were learning through discussions, and how they went about engaging in them. Quantitative analyses are used to investigate how the students' experience related to their performance. Key outcomes of the study include that the quality of the students' experience of learning through discussions is positively related to their performance and that face-to-face and online discussions have qualitatively different benefits for learning. © 2004, Taylor & Francis Group, LLC.
