In this paper, we present a first study at the level of lines. To identify line changes across several versions, we define the annotation graph which captures how lines evolve over time. The annotation graph provides more fine-grained software evolution information such as life cycles of each line and related changes: "Whenever a developer changed line 1 of version.txt she also changed line 25 of Library.java."}, keywords = {change, change analysis, change management, graph, lines of code, source code}, isbn = {1-59593-397-2}, doi = {http://doi.acm.org/10.1145/1137983.1138001}, url = {http://doi.acm.org/10.1145/1137983.1138001}, attachments = {https://flosshub.org/sites/flosshub.org/files/72MiningVersionArchives.pdf}, author = {Zimmermann, Thomas and Kim, Sunghun and Zeller, Andreas and Whitehead,Jr., E.
