A little reminder before we start. You need to have an off campus library log in to be able to search databases and catalogs for things restricted to UCF student use such as thesis and dissertation text, ebooks, and journal articles.
Part 3 Continued
i. Research Methods and Data Sources - http://guides.ucf.edu/research links you to a page with useful information for graduate students.
1. Read it
Searching the existing Dissertation Database
- Decide what your generic area is, in this case DSP. You need somewhere to start looking. Before you get more specific you want to know all possible people and databases that you could look for to gain information on what is worth while.
- The first place you want to check for topics is the library dissertation and thesis titles. The reason is that previous UCF students will be a lot more willing to give you a place to start. Especially if they just graduated, they may even give you code from their dissertation.
- Attempt to use review journals or databases to let you know what current and up and coming topics are, for example:
- Is there something more specific such as an intersecting field, this can help narrow your topic.
Example Thesis and Dissertation Search
I want to know what people are doing in the area of speaker recognition across the world. So I go to the ProQuest database search and look in the thesis and dissertation database searching on speaker recognition, and I limit my search to English documents.
49,703 results are returned! Here is a histogram of the papers released by decades, looks like the first paper returned was in 1912 and we even have some prerelease listings for next year, 2013. We want to know what the latest dissertations are right? So first let us narrow our search to the last two decades. How many papers is that?
45,316 results still remaining! Not small enough, lets take a look at that updated histogram,
From this subset I've taken the list of author keywords and created a wordle visualization of these keywords, take a look
Do you see just under Machine Learning there is the keyword signal processing? Lets narrow our search to the keywords signal processing as well.
And now we have 18! Yes! Lets look at these 18 titles and authors. Remember that these are dissertations or thesis so the authors have graduated from school in the last 10 years and are probably now the leading researcher in these areas. Also these dissertations have required multiple publications before they were written.

Remember this is not a perfect science, finding the right things is an art, so do these look like what we were looking for? Yes and no depending on your specific area, but its close.
More on searching next time but for now let me point out a good data visualization tool, just be sure to read the rules before using it http://www-958.ibm.com/software/data/cognos/manyeyes/
Here is a visualization of the data we found:
Until next time!
