Research

    • Currently a smorgasbord of different code analysis and visualization features.
    • Behind the scenes there is a consistent set of ideas soon to break through.
    • Research towards an infrastructure for context-driven software adaptation.
    • Support developers in building adaptive software
    • Support end-users with intelligent self-adaptive software.
    • ADOC-Pro - our adaptive document prompter - is not a new application.
    • The situation-specific adaptation of already existing applications.
    • Proof of concept realization of the CSI approach.
    • Web-Application based on an implementation in R developed by Dr. Svetlana Bulashevska

Publications

The focus of my own work is the definition of statically verifiable statements about desired structures (e.g. design pattern or properties like immutability) or unwanted structures (e.g., so-called “bad smells”), including the evolution of these statements [Speicher 2013, Speicher 2016]. As our infrastructure [Speicher, Rho, Kniesel 2007] uses Prolog at its core, we were able to prototypically apply results about update propagation. Based on these we can calculate how analysis results would change in consequence of a code restructuring, without having to carry out the restructuring [Tantius, Speicher, Behrend 2012]. As further elements of static analysis, we used the program dependence graph to identify the similarities and differences in cloned methods [Speicher, Bremm 2012]. We used type constraints for type generalization analysis [Speicher, Appeltauer, Kniesel, 2007, Speicher, Rho, Kniesel 2007]. In an existing approach for finding recurring patterns in software using formal concept analysis, we were able to elaborate the aspect of interaction [Heckmann, Speicher 2012]. In [Speicher, Nonnen, Bremm 2012] I sketched the proposal to implement tests for static analysis as annotated source code. Our plug-in displays as well the test result in the code. Using this approach, our students wrote significantly more tests than before. In this respect, I envision the integration of elements of prototyping into the process of developing static analyses.
