Generating Semantic Graph Corpora with Graph Expansion Grammar
Eric Andersson Johanna Björklund Frank Drewes Anna Jonsson
We introduce Lovelace, a tool for creating corpora of semantic graphs. The
system uses graph expansion grammar as a representational language, thus
allowing users to craft a grammar that describes a corpus with desired
properties. When given such grammar as input, the system generates a set of
output graphs that are well-formed according to the grammar, i.e., a graph
bank. The generation process can be controlled via a number of configurable
parameters that allow the user to, for example, specify a range of desired
output graph sizes. Central use cases are the creation of synthetic data to
augment existing corpora, and as a pedagogical tool for teaching formal
language theory.
