SentenceTransformer based on nomic-ai/modernbert-embed-base

This is a sentence-transformers model finetuned from nomic-ai/modernbert-embed-base on the touch-rugby-modernbert-pairs dataset. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

  What is the numerical difference between the teams on the field of play during a Drop-Off if a player has been sent to the sin bin?	24.5 For the avoidance of doubt for clauses 24.3 and 24.4 the non-offending Team will retain a numerical advantage on the Field of Play during the Drop-Off.25  Match Officials 25.1 The Referee is the sole judge on all match related matters inside the Perimeter for the Duration of a match, has jurisdiction over all players, coaches and officials and is required to: 25.1.1 Inspect the Field of Play, Line Markings and Markers prior to the commencement of the Match to ensure the safety of all participants.25.1.2 Adjudicate on the Rules of the game; 25.1.3 Impose any sanction necessary to control the match; 25.1.4 Award Tries and record the progressive score; 25.1.5 Maintain a count of Touches during each Possession; 25.1.6 Award Penalties for Infringements against the Rules; and 25.1.7 Report to the relevant competition administration any Sin Bins, Dismissals or injuries to any participant sustained during a Match.
