    Datasets

  • Corrected TimeBank is the corrected version of the TimeBank corpus. Since TimeBank 1.2 is distributed under license by the LDC, I cannot directly provide the corrected corpus. The zip file only includes the patch files of the corrected version of TimeBank and the script to generate the corrected version of the TimeBank corpus. Therefore, users need to obtain the original corpus and paste the corpus into the Dataset folder. Then, run \Dataset\script.sh on Linux Command Line to generate the corrected corpus.

    • Software

  • jTLEX is the Java library to perform temporal analysis of TimeML annotated texts. It takes TimeML annotated texts as input and then; extracts TimeML graphs from the texts, partitions TimeML graphs into temporally connected graphs, transforms them into Temporal Constraint Satiscfaction Problems (TCSPs), extracts the timelines of TCSPs, detects temporal inconsistencies, and identifies temporal indeterminacies. [jTLEX Website]

  • pyTLEX is the Python library to perform temporal analysis of TimeML annotated texts. It takes TimeML annotated texts as input and then; extracts TimeML graphs from the texts, partitions TimeML graphs into temporally connected graphs, transforms them into Temporal Constraint Satiscfaction Problems (TCSPs), extracts the timelines of TCSPs, detects temporal inconsistencies, and identifies temporal indeterminacies. [Python Library]

  • EvalTDT is a software to evaluate information loss during transforming temporal graphs to temporal dependency trees. It was written in Java, building upon the JaCoP constraint solving tool, and takes as input TimeML (.tml), Story Workbench (.sty), or TDT (.tdt) files. The publicly available code and data are available through the FIU Dataverse.

  • TLEX-Visual is the Java library to visualize the TimeML graphs of TimeML annotated texts and provide a visual representation of temporal analysis of the TimeML graphs, including partitioning, transforming, extracting timelines, detecting inconsistency, and identifying indeterminacy.
