Consistent, easy-to-use, friendly user interface.


The CTAP system is deployed as a Web application, which strikes a balance between usability, flexibility and cross-platform compatibility. The GUI provided on the Web makes it easy to access, user-friendly and platform neutral. The CTAP client frontend was written with Google Web Toolkit7 (GWT), an open source and free technology that enables productive development of high-performance web applications. This avoids the necessity to compile the software for different operating systems, which has been proved to be a major frustration for small development teams or single developers who do not have enough resources to deal with platform differences.


Modularized, reusable, and collaborative development of analysis components.


The CTAP analysis back-end is written under the UIMA framework. Each analysis unit is implemented as a UIMA AE. Since a lot of the AEs are commonly required by different complexity features, modularizing analysis into smaller AEs makes it easier to reuse and share components. The AEs included into CTAP are open sourced and we encourage contribution from feature developers. A community effort will enhance complexity research to a greater extent.


Flexible corpus and feature management.


This feature is a luxury in light of the existing complexity analysis tools. However, this feature is of special value to users with lower information and communication technology competence. Users choose from the feature repository the system provides a set of features that meet their needs, the CTAP system then generates a UIMA AAE to extract the chosen feature values. It frees users from tediously editing analyzer source code, which is also often error-prone.
