Description

This paper describes a project in Germany which explores metaphores in both religious and secular literatures. Here, the authors used NLP methods to process a corpus of pre-digitized Arabic texts from Jordan. These texts are commentaries on the Qur'an, the sacred text of Islam. They deployed these methods to explore the metaphor of, "The Straight Path" and the words used by various commentators while explaining verses in which this phrase occurs. The paper is noteworthy for its application of NLP to Arabic text.

This paper's data repository at https://zenodo.org/records/11206706 has only 41 views as of the time of this commit. It is a highly specialized paper appealing to a very small audience of scholars in Religious Studies or the Digital Humanities and has not been widely remarked upon.

Motivation

I selected this paper because it was suggested to me by my friend in UA's MENAS department, Dr. Scott Lucas. He wanted me to explain and evaluate the usefulness of their technique. The paper relates to my long-time interest in sacred languages (theolinguistics?), specifically the linguistic aspects of exegetical texts in various Islamicate languages.

I've reviewed the paper titled "Text Mining Tafsir: Compilation and Preliminary Explorations of a Curated Corpus of 80 Qurʾ anic Commentaries" jdir-article-p97_4.pdf. The authors introduce a curated corpus of 80 Arabic Tafsir (tafsīr) works compiled as part of a project investigating the development of Qurʾ anic WAY metaphors. They present systematic quantitative and qualitative characteristics of the Tafsir corpus and its metadata, and demonstrate the potential of computer-driven analyses of the Tafsir corpus through a clustering of selected subchapters and sentences.

The paper discusses the importance of Tafsir as a genre, its history, and its doctrinal diversification. The authors highlight the challenges of working with a large corpus of Tafsir texts, including issues with bibliographical information, unknown editions, and the absence of metadata. They also discuss the process of corpus compilation, data cleaning, and normalization.The authors present an exploratory data analysis of the corpus, including an overview of the chronological distribution of the Tafsirs, regional distribution, and corpus bias. They also analyze the distribution of quotes in the Tafsir works, including Qurʾ anic, Hadith, and poetry quotes.

One of the key findings is that the corpus contains a significant number of quotes from various sources, with some Tafsirs having a high absolute number of quotes and others having a low quote count. The authors also identify a specific subcategory of Tafsirs, namely popularizing Tafsirs, which tend to contain fewer direct quotations.

The paper also presents a case study on clustering selected subchapters and sentences from the Tafsir corpus using text mining methods. The authors use a pre-trained language model to create document embeddings and apply HDBSCAN to cluster the data. They identify several clusters of semantically similar Tafsir subchapters and sentences, including a cluster discussing the concept of the "road to hell" and another cluster discussing the value of sincerity.

Experience using the LLM

I think this model performed quite well and conveyed the gist accurately. However, I wouldn't rely on this or any LLM's output in a paper nor any informed conversation about the paper without verifying each of its claims.

The model answered my questions quickly; I did not experience the notable lags such as those I encounter when using AI-coding assistants at work.

It initially provided a summary of the paper without prompting after reading the PDF, which thankfully was a text PDF instead of an image. This summary was thorough and accurate based on my reading of the paper. In fact, I think the summary was quite good and readily usable.

It correctly summarized the authors' approach and their innovation in using computational linguistics as a tool for analyzing Islamic exegesis texts. I feel the authors would be flattered by the LLM's summary.

It correctly understood "next steps" as also meaning future projects, highlighting the effectiveness of co-occurrances, wether near or distant.

The LLM presented some uncanny and welcome insights. For example, it suggested future funding sources such as the National Endowment for the Humanities (NEH), an entity not mentioned in the original paper.

Is this somehow related to how this LLM is hosted by Indiana University? We could test that in the future by using independently installed local LLMs. This kind of experimentation implies an entirely new field of experimental "humanities" However, the subjects of study would be non-sentient digital models of the aggregated language production of sentient humans, so still humanities! Someone has probably suggested this already, although my web search for "experimental humanities by studying LLM output" delivered so much, yet so little about my intent, except possibly this? https://news.stanford.edu/stories/2025/07/ai-social-science-research-simulated-human-subjects

In another answer, it tenderfully raised concerns about the result's accuracy and validity:

1. Limited scope: The authors' focus on a specific corpus of Tafsir literature and a specific research question may limit the generalizability of their results.
2. Dependence on computational methods: The authors' reliance on computational methods may raise concerns about the accuracy and validity of their results.

Errors and limitations of the LLM

I noticed that sometimes the model really tried hard to make an answer fit the question, even when the question is not quite relevant to the paper.

For example, when I asked it what the authors were proposing, the LLM listed four points relating to what the authors did in the paper: They "introduce a corpus", "they present a systematic analysis of the Tafsir corpus," and "they apply text mining methods". The authors did not propose much unless we infer "propose" to mean the overall intent of the paper (which I do). With this definition, the answer was not spot on. After its typical listing of points, it does actually get it right: "Overall, the authors propose that computational linguistics technologies can be effectively used to analyze large corpora of Tafsir texts..."

It has a propensity to making lists, which are not always ordered to most effectively answer the question. In the motivation question, it finally gets it right on point 2 of 3. Now, I mmight be being harsh because the authors do front the Qur'anic metaphor as their purpose. I felt that this was just a winking nod to the project in which the PI resides, "part of the Collaborative Research Center 'Metaphors of Religion' at Ruhr University Bochum, Germany". The paper could have left out the metaphor exploration and still have been just fine, and shorter.

I intentionally framed the LLM's context by using the word "Islamicate", introduced by Hodgson (1974). It applies to a multilingual and multicultural civilization, while the corpora used in this paper are entirely in Arabic. Arabic is central to Islamicate cultures, but is only one of many civilizationally important literary languages in Islamicate cultures, such as Persian, Turkish, Urdu, Swahili and Malay. The authors of the paper acknowledge this, "it includes only Arabic-language Tafsirs, overlooking the rich non-Arabic Tafsir tradition from regions such as India, Iran, and Southeast Asia."

There are some places where the model makes strange sugestions whose roots are difficult to discern. It suggested network analysis and multimodal analysis as one of the next steps. However, networks was only mentioned in the paper in the context of networks of citations on p.126 while listing other initiatives in Islamic Digital Humanities.

In one of my questions, I intentionally and incorrectly accused it of ignoring the limitaitons of the approach described in the paper. In response, it stoked my ego with, "You are correct that my previous response only highlighted the positive aspects of the paper's work". This is a total lie.
