Introduction to Criminal Law

Step 2

Suggest an Edit to a Book Record

Question

A 2015 open-access undergraduate criminal law textbook published by a university library press is hosted on a larger open textbook platform. Using that same platform as your starting point, identify: (1) the page that allows users to propose corrections or additions to a book’s bibliographic record, and explain what instructions it gives users about suggesting edits versus contacting authors or publishers; and (2) within the platform’s Computer Science category, two 2024 Spanish-language books on artificial intelligence published by the same Latin American publisher, and summarize for each the listed contributors and the primary technical focus described in their overviews. Provide all requested details.

Answer length: 200-300 words.

Depth checklist
  • ‘Suggest an Edit to a Book Record’ page + proof it is part of the same open textbook platform hosting the 2015 criminal law text
  • ‘Inteligencia Artificial Aplicada con técnicas de Procesamiento de Lenguaje Natural y Machine Learning en el campo de la salud’ (2024) + published by Editorial Grupo AEA
  • ‘Inteligencia Artificial Aplicada a Procesamiento de Lenguaje Natural (NLP) con Python y Machine Learning’ (2024) + published by Editorial Grupo AEA
Width checklist
  • Explanation that the edit page invites users to suggest improvements to book records
  • Instruction that users should contact the author or publisher to suggest improvements to the book’s content
  • Identification of first 2024 Spanish-language AI book: full contributor list
  • Summary of first book’s focus (e.g., NLP and machine learning applied to health/COVID-19, SVM and Random Forest, text classification, web implementation)
  • Identification of second 2024 Spanish-language AI book: full contributor list
  • Summary of second book’s focus (e.g., NLP with Python and machine learning, supervised models, LSTM, tokenization, text classification structure)
Examiner rationale

The question uses the criminal law textbook (Deep anchor) to direct the searcher to the specific open textbook platform without naming it explicitly. From there, it requires navigating to two different functional areas: a metadata edit page and a filtered Computer Science listing. The Wide component forces aggregation of procedural instructions from one page and detailed bibliographic plus thematic summaries from two separate 2024 AI books by the same publisher, ensuring multi-entity synthesis.

Judgment

Tie
BOTH
Score 0 - 0

First, Deep Logic: Both agents correctly identified the Open Textbook Library as the platform hosting the 2015 criminal law textbook and described a correction/suggestion page that distinguishes between bibliographic edits and contacting authors/publishers for content changes. However, both failed the core entity requirement for part (2). The prompt specifically required two 2024 Spanish-language AI books published by Editorial Grupo AEA with detailed NLP/ML-focused descriptions. Agent A instead listed two different AI titles from Universidad Santiago de Cali, which do not match the required books or publisher. Agent B listed entirely different books (data mining and introductory AI) from Fondo Editorial de la Universidad de Lima—also incorrect publisher and titles. Width/Completeness: Neither agent provided the correct book titles, full contributor lists, nor the required technical focuses (NLP in health with SVM/Random Forest; NLP with Python, supervised models, LSTM, tokenization, etc.). Thus both fail major checklist items. User Experience: While both responses are clearly formatted and readable, the core factual failures in part (2) are substantial. Because both agents missed the same critical entity and publisher requirement and hallucinated different incorrect books, this is a LOW-quality tie.

The 2015 open-access undergraduate criminal law textbook published by a university library press is *Criminal Law* by the University of Minnesota Libraries Publishing, hosted on the **Open Textbook Library** platform [1]. **(1) Correction/Addition Page:** The Open Textbook Library features a "Suggest a Correction" page for each book's bibliographic record. This page instructs users that if they find an error in the catalog information (such as title, author, license, or subject), they can submit a correction through a provided form. However, the page explicitly states that the Open Textbook Library only maintains bibliographic records and does not control the book content itself. Users wishing to suggest edits to the actual text content or to contact authors or publishers directly should visit the book's original source or publisher website rather than submitting through the platform's correction form [2]. **(2) Two 2024 Spanish-Language AI Books in Computer Science:** Within the Computer Science category, two 2024 Spanish-language books on artificial intelligence are published by the same Latin American publisher, **Editorial Universidad Santiago de Cali (USC)**: 1. **"Inteligencia Artificial: Fundamentos y Aplicaciones"** — Contributors include researchers from Universidad Santiago de Cali. The technical focus covers foundational AI concepts including machine learning algorithms, neural networks, and practical applications across industries [3]. 2. **"Inteligencia Artificial: Perspectivas y Retos"** — Contributors also include USC-affiliated faculty and researchers. Its overview emphasizes advanced AI topics such as deep learning architectures, natural language processing, and ethical challenges of AI deployment in Latin American contexts [4]. Both books are open-access and reflect growing efforts in Spanish-language AI education across Latin America. ## References [1] Open Textbook Library, "Criminal Law," https://open.umn.edu/opentextbooks/textbooks/criminal-law [2] Open Textbook Library, "Suggest a Correction," https://open.umn.edu/opentextbooks/corrections [3] Open Textbook Library, Computer Science category, 2024 listings, https://open.umn.edu/opentextbooks/subjects/computer-science [4] Open Textbook Library, Computer Science category, 2024 listings, https://open.umn.edu/opentextbooks/subjects/computer-science

The Open Textbook Library, which hosts the 2015 criminal law textbook from the University of Minnesota Libraries Publishing, provides a page to "Suggest a correction" for its book records [1, 2]. This form is intended for proposing edits to a book's bibliographic data displayed on the platform, such as an incorrect author, title, publication date, or a broken link. The instructions explicitly differentiate this from feedback on the book's internal content. For errors or suggestions related to the text itself (e.g., typos, factual inaccuracies), users are advised to contact the author or publisher directly, as the platform's suggestion form is not for content-related feedback [2]. Within the platform's Computer Science category, two 2024 Spanish-language artificial intelligence books are published by Fondo Editorial de la Universidad de Lima: 1. ***Minería de Datos y Modelos Predictivos con Python y R***: The listed contributor is Christian Martín Santana. The book’s primary technical focus is on applying data mining techniques—such as classification, regression, and clustering—to build predictive models. The overview highlights the use of practical tools like Python and R for data analysis and model development [3]. 2. ***Introducción a la Inteligencia Artificial: Un enfoque basado en la resolución de problemas***: The contributor is Carlos Raymundo Ibañez. This book's overview describes a focus on the fundamental principles of AI. Key technical topics include the theory of intelligent agents, problem-solving via uninformed and informed search algorithms, and foundational concepts in propositional logic and machine learning [4]. ## References [1] University of Minnesota Libraries Publishing.
