Blog Post #3-Exploring Text visualization Tools


I choose a novel called ‘A short history of Rhode Island’ from Project Gutenberg (http://www.gutenberg.org) for this task. I created a word cloud for this assignment using Wordle. I modified this image using color and layout icons and posted in PLS. I also created a visualization of the same corpus using Voyant visualization tools. It was not difficult to use this tool to reveal this corpus. It took some times to reveal the whole novel. This tool helped me to find some keywords that played a very important role in the novel. We can list the frequency (how many times each word is used in this story) of words using this tool. One of the most important characteristics of this tool is the ability to show shifting word frequencies of multiple terms. We can graph for different words using this tool. For example, I graphed words like ‘Williams’, ‘colony,’ and ‘plymouth’ for this task using this tool. We can also compare patterns of graph using this tool, which would be very helpful for our students. Students can analyze different kinds of keywords using Voyant tools.  I am teaching an electrical engineering course (MAE 213) in which students need to solve problems (e.g. identify problems, present topics, analyze problems, attempt problem solutions, respond to problems, think carefully, or evaluate alternatives). As a requirement of this course students need to do some projects using simulation/visualization tools such as Multisim, Matlalab, and Pspice to build their carrier in a professional way. For these purposes students need to write one or two page reflections of what they learned from their project so they can deposit their project in E-portfolio. Some students are also interested in working in research related to the electrical engineering area. I think this tool is very useful for students who are interested in writing a project report in class, publishing their research in journal or presenting their research in national and international conferences.

Challenge and Opportunities in the Digital Humanities



I went through the "Print Scholarship and Digital resources" article. Author mentioned that “the the realm of the visual that we are considering some of the most interesting interrelationships of print scholarship and digital resources.” Author also mentioned that “while much of this knowledge has been lost in the textual obsession of print culture, the graphical interface of the computer screen has helped us reconnect to the world of the visual and recognize that we can relearn a long-neglected vocabulary of interpretation.” I agree with author ideas. But I realize that visualization is a challenge for the humanities scholarship. In engineering science research, the phrase visualization explicates the field of study that uses interactive graphical tools to explore and present graphically a represented 2D/3D diagram or digitally represented data that might be simulated, constructed, measured, or analyzed. Visualization is usually taught in undergraduate and graduate-level courses in the engineering science area. The focus is on teaching students who are already versed in computer systems and technology how to create innovative information visualization tools.  Students in such classes typically create a project, which serves as a basis for their grade in the course. Visualization is a skill that must be practiced for simplicity, and that takes time. Engineering schools teach courses using virtual lab such as Matlab, Multisim, Pspice, and Electronic workbench by making students construct, design, analyze, simulate and redesign. Therefore, I am planning to teach an undergraduate course called electric circuit course using Multisim to solve electric circuit problems that require computer simulation and visualization in order to increase students’ understanding of electrical circuit theories and concepts. May be it an enormous challenge for me to select the material to teach this course using Multisim. Should the course focus exclusively on electric circuits diagram visualization? Can Multisim simulation software provide adequate experience for all these students? Will the software experience sufficiently reinforce concepts such as electric circuit theory?
