SentenceTransformer based on sentence-transformers/all-mpnet-base-v2

This is a sentence-transformers model finetuned from sentence-transformers/all-mpnet-base-v2. 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.

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

    'What impact do automated systems have on underserved communities?',
    "automated systems make on underserved communities and to institute proactive protections that support these \ncommunities. \n•\nAn automated system using nontraditional factors such as educational attainment and employment history as\npart of its loan underwriting and pricing model was found to be much more likely to charge an applicant who\nattended a Historically Black College or University (HBCU) higher loan prices for refinancing a student loan\nthan an applicant who did not attend an HBCU. This was found to be true even when controlling for\nother credit-related factors.32\n•\nA hiring tool that learned the features of a company's employees (predominantly men) rejected women appli\xad\ncants for spurious and discriminatory reasons; resumes with the word “women’s,” such as “women’s\nchess club captain,” were penalized in the candidate ranking.33\n•\nA predictive model marketed as being able to predict whether students are likely to drop out of school was",
    'on a principle of local control, such that those individuals closest to the data subject have more access while \nthose who are less proximate do not (e.g., a teacher has access to their students’ daily progress data while a \nsuperintendent does not). \nReporting. In addition to the reporting on data privacy (as listed above for non-sensitive data), entities devel-\noping technologies related to a sensitive domain and those collecting, using, storing, or sharing sensitive data \nshould, whenever appropriate, regularly provide public reports describing: any data security lapses or breaches \nthat resulted in sensitive data leaks; the number, type, and outcomes of ethical pre-reviews undertaken; a \ndescription of any data sold, shared, or made public, and how that data was assessed to determine it did not pres-\nent a sensitive data risk; and ongoing risk identification and management procedures, and any mitigation added',

`What information should designers and developers provide about automated systems to ensure transparency?`	You should know that an automated system is being used, and understand how and why it contributes to outcomes that impact you. Designers, developers, and deployers of automat ed systems should provide generally accessible plain language docu mentation including clear descriptions of the overall system func tioning and the role automation plays, notice that such systems are in use, the individual or organization responsible for the system, and ex planations of outcomes that are clear, timely, and accessible. Such notice should be kept up-to-date and people impacted by the system should be notified of significant use case or key functionality chang es. You should know how and why an outcome impacting you was de termined by an automated system, including when the automated system is not the sole input determining the outcome. Automated systems should provide explanations that are technically valid, meaningful and useful to you and to any operators or others who

`What specific technical questions does the questionnaire for evaluating software workers cover?`	questionnaire that businesses can use proactively when procuring software to evaluate workers. It covers specific technical questions such as the training data used, model training process, biases identified, and mitigation steps employed.55 Standards organizations have developed guidelines to incorporate accessibility criteria into technology design processes. The most prevalent in the United States is the Access Board’s Section 508 regulations,56 which are the technical standards for federal information communication technology (software, hardware, and web). Other standards include those issued by the International Organization for Standardization,57 and the World Wide Web Consortium Web Content Accessibility Guidelines,58 a globally recognized voluntary consensus standard for web content and other information and communications technology. NIST has released Special Publication 1270, Towards a Standard for Identifying and Managing Bias
