Wartbarkeit spielt eine zentrale Rolle für die Langlebigkeit von Softwareprojekten. Ein wichtiger Teil der Wartbarkeit besteht darin, dass die natürlichsprachliche Dokumentation des Quelltextes einen guten Einblick in das Projekt und seinen dazugehörigen Quelltext liefert. Zur besseren Wartbarkeit dieser beiden Software-Artefakte besteht die Aufgabe dieser Arbeit darin, Verbindungen zwischen den Elementen dieser beiden Artefakte aufzubauen. Diese Verbindungen heißen Trace Links und können für verschiedene Zwecke der Wartbarkeit genutzt werden. Diese Trace Links ermöglichen zum Beispiel die Inkonsistenzerkennung zwischen den beiden Software-Artefakten oder können auch für verschiedene Analysen benutzt werden. Um diese Trace Links nachträglich aus den beiden Software-Artefakten natürlichsprachlicher Dokumentation und Quelltext zu gewinnen, wird das bereits bestehende ArDoCo Framework benutzt und auf das Software-Artefakt Quelltext erweitert. Ebenfalls werden ArDoCos bestehende Entscheidungskriterien auf den neuen Kontext angepasst. Der neuartige Kontext führt zu Herausforderungen bezüglich der Datenmenge, die durch neue Entscheidungskriterien adressiert werden. Dabei zeugen die Ergebnisse dieser Arbeit eindeutige von Potenzial, weswegen weiter darauf aufgebaut werden sollte.

Natural Language Software Architecture Documentation ( NLSAD ) and Software Architecture Model ( SAM) provide information about a software systems design and qualities. Inconsistencies between these artifacts can negatively impact the comprehension and evolution of the system. ArDoCo is an approach that was proposed in prior work by Keim et al. to find such inconsistencies and relies on Traceability Link Recovery (TLR) between entities in the NLSAD and SAM . ArDoCo searches for Unmentioned Model Elements (UMEs) in the model and Missing Model Elements (MMEs) in the text using the linkage information. ArDoCo’s approach shows promising results but has room for improvement regarding precision due to falsely identified textual entities. This work proposes using informal diagrams from the Software Architecture Documentation (SAD) to improve this. The approach performs an additional TLR between the textual entities and the diagram entities. According to heuristics, the linkage of textual entities and diagram entities is utilized to increase or decrease the confidence in textual entities. The Diagram Text TLR and its impact on ArDoCo’s performance are evaluated separately using the same data set as previous work by Keim et al. The data set was extended to include informal diagrams. The Diagram Text TLR achieves a good F1-score with Optical Character Recognition (OCR) of 0.54. The approach improves the MME detection (0.77→0.94 accuracy) by lowering the amount of falsely identified textual entities (0.39→0.69 precision) with a negligible impact on recall. The UME detection and ArDoCo ’s NLSAD to SAM are slightly positively impacted and continue to perform excellently. The results show that using informal diagrams to improve entity recognition in the text is promising. Room for improvement exists in dealing with issues related to OCR and diagram element processing.

In software development, software architecture plays a vital role in developing and maintaining software systems. It is communicated through artifacts such as software architecture documentation (SAD) and software architecture models (SAM). However, maintaining consistency and traceability between these artifacts can be challenging. If there are inconsistencies or missing links, it can lead to errors, misunderstandings, and increased maintenance costs. This thesis proposes an approach for recovering traceability links of software architecture relations between natural language SAD and SAM. The approach involves the use of Pre-trained Language Models (PLMs) such as BERT and ChatGPT and supports different extraction modes and prompt engineering techniques for ChatGPT, as well as different model variants and training strategies for BERT. The proposed approach is integrated with ArDoCo, a tool that detects inconsistencies and recovers trace links between software artifacts. ArDoCo is used for pre-processing the SAD text and parsing the SAM, thus facilitating the traceability link recovery process. In order to assess the performance of the framework, a gold standard of SAD and SAM created from open-source projects is utilized. The evaluation shows that the ChatGPT approach has promising results in relation extraction with a recall of 0.81 and in traceability link recovery with an F1-score of 0.83, while BERT-based models struggle due to the lack of domain-specific training data.
