KDC: A Computer Program for the Analysis of Coherence Relations in Discourse

KDC is a statistical software tool environment specifically intended to support the analysis and exploitation of local coherence relations in traversal data during comprehension or production data (e.g., recall, summarization, think-aloud).

Briefly, KDC analysis is a categorical time-series analysis which views the observed data as an ordered sequence of complex propositions. The researcher postulates several directed graphs corresponding to different possible predictions regarding how the sequence of propositions is organized and then the relative contribution of each directed graph is estimated.

Golden (1998), Jaynes and Golden (2003), and the recent thesis by Ismaili (2012) are good places to start learning about KDC analysis.

KDC SOFTWARE (Academic License for Non-Commercial Use Only)

Currently, we are only supporting KDC on PC computers. Eventually it will be made available for MACS and LINUX operating systems.

STEP 1: Download and Install MATLAB Compiler Run-Time Library

DOWNLOAD MATLAB MCR INSTALLER

After you have downloaded the MCRINSTALLER, click on the MCRINSTALLER and it will walk you through the installation procedure for installing the MATLAB Compiler Run-Time Library on your computer.

You have legal permission to install this MATHWORKS software to run KDC but you do not have permission to use the MATHWORKS software for any other purpose.

Uninstalling the MATLAB Compiler Run-Time Library software. Do not delete the MCRINSTALLER software from your machine. If you ever want to uninstall the MATLAB Compiler Run-Time Library software then you will need to use the MCRINSTALLER for a "clean" uninstall. To uninstall, simply go through the motions as if you wanted to install the software, the MCRINSTALLER is smart enough to figure out that the software is already installed and will ask you if you want to uninstall the software. This is the best way to uninstall the MATLAB Compiler Run-Time Library. After you have completed this uninstallation procedure, then feel free to delete anything you like!

STEP 2: Download the KDC Software

DOWNLOAD KDC SOFTWARE

Note that the KDC Software is for ACADEMIC use only to support scientific research. Also note that the KDC software is not a commercial software package and we are constantly updating and revising the software. Please check the website KDC Software Updates for KDC software updates and fixes and known problems.

Note that if you skip Step 1 then the downloaded KDC software will not work properly (or at all) on your machine unless you just happen to already have MATLAB R2011b installed on your computer. In that case, you can skip Step 1; otherwise YOU MUST HAVE INSTALLED the MATHWORKS COMPILER RUN-TIME LIBARY on your computer before installing KDC!!!

STEP 3: Download the Example KDC work folder

DOWNLOAD EXAMPLE KDC WORK FOLDER

After you download this folder, unzip the folder. When you start up the KDC software you will need to identify this folder. Then you should load in one of the example models. There is a text file in the folder called KDChelpREADME.txt which should be helpful. Example data files are neurostudents.data and psychstudents.data. Example model files are BiDirectionalALL.model and BiDirectionalSemantic.model.

NATIONAL SCIENCE FOUNDATION (NSF) FUNDING SUPPORT

NSF AWARD 0113669

This research was funded in part by the NSF Information Technology Research Initiative through the Research and Learning on Education Program jointly with the Directorate for Social, Behavioral, and Economic Sciences and the Directorate for Computer & Information Science and Engineering and the Directorate for Education and Human Resources.

NSF AWARD 0624983

This research was also funded in part by NSF Award 0624983 entitled Dissertation Research: Statistical Models of Hypertext Comprehension to Dr. Richard Golden to support the dissertation research of Dr. Perwaiz Ismaili. NSF Award 0624983 was funded by the Directorate for Social, Behavioral, and Economic Sciences (SBE), Division of Social and Economic Sciences (SES), Methodology, Measurement and Statistics (MMS).
