Semantic Hypergraphs
Telmo Menezes, Camille Roth

TL;DR
Semantic Hypergraphs offer a novel, interpretable knowledge representation that combines machine learning and symbolic methods, enabling effective NLP tasks like information extraction and co-reference resolution.
Contribution
The paper introduces Semantic Hypergraphs, a hybrid, recursive model that captures natural language hierarchy and variability, advancing open-adaptive NLP approaches.
Findings
High precision in parsing diverse texts
Effective in information extraction and co-reference resolution
Supports knowledge inference and taxonomy building
Abstract
Approaches to Natural language processing (NLP) may be classified along a double dichotomy open/opaque - strict/adaptive. The former axis relates to the possibility of inspecting the underlying processing rules, the latter to the use of fixed or adaptive rules. We argue that many techniques fall into either the open-strict or opaque-adaptive categories. Our contribution takes steps in the open-adaptive direction, which we suggest is likely to provide key instruments for interdisciplinary research. The central idea of our approach is the Semantic Hypergraph (SH), a novel knowledge representation model that is intrinsically recursive and accommodates the natural hierarchical richness of natural language. The SH model is hybrid in two senses. First, it attempts to combine the strengths of ML and symbolic approaches. Second, it is a formal language representation that reduces but tolerates…
