| 38 | +abstract: > |
| 39 | + There are a multitude of software artifacts which need to |
| 40 | + be handled during the development and maintenance of a |
| 41 | + software system. These artifacts interrelate in multiple, |
| 42 | + complex ways. Therefore, many software engineering tasks |
| 43 | + are enabled — and even empowered — by a clear |
| 44 | + understanding of artifact interrelationships and also by |
| 45 | + the continued advancement of techniques for automated |
| 46 | + artifact linking. |
| 47 | + However, current approaches in automatic Traceability Link |
| 48 | + Recovery (TLR) target mostly the links between specific |
| 49 | + sets of artifacts, such as those between requirements and |
| 50 | + code. Fortunately, recent advancements in Large Language |
| 51 | + Models (LLMs) can enable TLR approaches to achieve broad |
| 52 | + applicability. Still, it is a nontrivial problem how to |
| 53 | + provide the LLMs with the specific information needed to |
| 54 | + perform TLR. |
| 55 | + In this paper, we present LiSSA, a framework that |
| 56 | + harnesses LLM performance and enhances them through |
| 57 | + Retrieval-Augmented Generation (RAG). We empirically |
| 58 | + evaluate LiSSA on three different TLR tasks, requirements |
| 59 | + to code, documentation to code, and architecture |
| 60 | + documentation to architecture models, and we compare our |
| 61 | + approach to state-of-the-art approaches. |
| 62 | + Our results show that the RAG-based approach can |
| 63 | + significantly outperform the state-of-the-art on the |
| 64 | + code-related tasks. However, further research is required |
| 65 | + to improve the performance of RAG-based approaches to be |
| 66 | + applicable in practice. |
