Algraeph is a tool for manual alignment of
linguistic graphs, such as phrase structure trees
or dependency structures, where each node
corresponds to a subsequence of the analyzed
input sentence. It allows you to express the
similarity between two graphs by aligning their
nodes and attaching relation labels to these
alignments. Graphs are read from one or more
graphbanks (or treebanks) in the GraphML or
Alpino formats. Alignment relations are
user-defined and are stored in a simple XML
format, which can be used for further processing.
The resulting parallel graph corpus is a useful
data set for many tasks in computational
linguistics and natural language processing.
