SentenceTransformer based on BAAI/bge-small-en-v1.5

This is a sentence-transformers model finetuned from BAAI/bge-small-en-v1.5. It maps sentences & paragraphs to a 512-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("raul-delarosa99/bge-small-en-v1.5-RIRAG_ObliQA")
# Run inference
sentences = [
    'Could you provide detailed guidance on the acceptable threshold for "significant loss" to clients in the context of IT infrastructure resilience for virtual asset service providers?',
    '60) REGULATORY REQUIREMENTS FOR AUTHORISED PERSONS ENGAGED IN REGULATED ACTIVITIES IN RELATION TO VIRTUAL ASSETS Security measures and procedures IT infrastructures should be strong enough to resist, without significant loss to Clients, a number of scenarios, including but not limited to: accidental destruction or breach of data, collusion or leakage of information by employees/former employees, successful hack of a cryptographic and hardware security module or server, or access by hackers of any single set of encryption/decryption keys that could result in a complete system breach.',
    'APP8.A8.11.1 An Insurer must calculate the asset management risk component in respect of a Long Term Insurance Fund according to the method set out in Rule A4.13, applied as though all references in that Rule to an Insurer were instead references to that fund.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 512]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]

`Under Rules 7.3.2 and 7.3.3, what are the two specific conditions related to the maturity of a financial instrument that would trigger a disclosure requirement?`	`7.3.4 Events that trigger a disclosure. For the purposes of Rules 7.3.2 and 7.3.3, a Person is taken to hold Financial Instruments in or relating to a Reporting Entity, if the Person holds a Financial Instrument that on its maturity will confer on him: (1) an unconditional right to acquire the Financial Instrument; or (2) the discretion as to his right to acquire the Financial Instrument.`
`Best Execution and Transaction Handling: What constitutes 'Best Execution' under Rule 6.5 in the context of virtual assets, and how should Authorised Persons document and demonstrate this?`	17.1.4 The following COBS Rules should be read as applying to all Transactions undertaken by an Authorised Person conducting a Regulated Activity in relation to Virtual Assets, irrespective of any restrictions on application or any exception to these Rules elsewhere in COBS - (a) Rule 3.4 (Suitability); (b) Rule 6.5 (Best Execution); (c) Rule 6.7 (Aggregation and Allocation); (d) Rule 6.10 (Confirmation Notes); (e) Rule 6.11 (Periodic Statements); and (f) Chapter 12 (Key Information and Client Agreement).
`How does the FSRA define and evaluate "principal risks and uncertainties" for a Petroleum Reporting Entity, particularly for the remaining six months of the financial year?`	10.1.7.(2) A Reporting Entity must: (a) prepare such report: (i) for the first six months of each financial year or period, and if there is a change to the accounting reference date, prepare such report in respect of the period up to the old accounting reference date; and (ii) in accordance with the applicable IFRS standards or other standards acceptable to the Regulator; (b) ensure the financial statements have either been audited or reviewed by auditors, and the audit or review by the auditor is included within the report; and (c) ensure that the report includes: (i) except in the case of a Mining Exploration Reporting Entity or a Petroleum Exploration Reporting Entity, an indication of important events that have occurred during the first six months of the financial year, and their impact on the financial statements; (ii) except in the case of a Mining Exploration Reporting Entity or a Petroleum Exploration Reporting Entity, a description of the principal risks and uncertainties for the remaining six months of the financial year; and (iii) a condensed set of financial statements, an interim management report and associated responsibility statements.
