Connecting the Dots: Inferring Patent Phrase Similarity with Retrieved Phrase Graphs

arXiv:2403.16265v1 Announce Type: new
Abstract: We study the patent phrase similarity inference task, which measures the semantic similarity between two patent phrases. As patent documents employ legal and highly technical language, existing semantic textual similarity methods that use localized contextual information do not perform satisfactorily in inferring patent phrase similarity. To address this, we introduce a graph-augmented approach to amplify the global contextual information of the patent phrases. For each patent phrase, we construct a phrase graph that links to …
