Abstract

The challenge of making flexible, standard, and early medical diagnoses is significant. However, some limitations are not fully overcome. First, the diagnosis rules established by medical experts or learned from a trained dataset prove static and too general. It leads to decisions that lack adaptive flexibility when finding new circumstances. Secondly, medical terminological interoperability is highly critical. It increases realism and medical progress and avoids isolated systems and the difficulty of data exchange, analysis, and interpretation. Third, criteria for diagnosis are often heterogeneous and changeable. It includes symptoms, patient history, demographic, treatment, genetics, biochemistry, and imaging. Symptoms represent a high-impact indicator for early detection. It is important that we deal with these symptoms differently, which have a great relationship with semantics, vary widely, and have linguistic information. This negatively affects early diagnosis decision-making. Depending on the circumstances, the diagnosis is made solo on imaging and some medical tests. In this case, although the accuracy of the diagnosis is very high, can these decisions be considered an early diagnosis or prove the condition is deteriorating? Our contribution in this paper is to present a real medical diagnostic system based on semantics, fuzzy, and dynamic decision rules. We attempt to integrate ontology semantics reasoning and fuzzy inference. It promotes fuzzy reasoning and handles knowledge representation problems. In complications and symptoms, ontological semantic reasoning improves the process of evaluating rules in terms of interpretability, dynamism, and intelligence. A real-world case study, ADNI, is presented involving the field of Alzheimer’s disease (AD). The proposed system has indicated the possibility of the system to diagnose AD with an accuracy of 97.2%, 95.4%, 94.8%, 93.1%, and 96.3% for AD, LMCI, EMCI, SMC, and CN respectively.

  • Fuzzy logic systems allow for expert rule-based reasoning that accommodates uncertainty and vagueness, which are common characteristics in psychiatric data.

    “Fuzzy logic systems, by contrast, allow for expert rule-based reasoning that accommodates uncertainty and vagueness which are common characteristics in psychiatric data”

    From A hybrid fuzzy logic–Random Forest model to predict psychiatric treatment order outcomes: an interpretable tool for legal decision support (2025) · cites this paper as Shoaip et al., 2024

    The Fuzzy inference section says diagnosis rules are created or advised by an expert and that fuzzy inference manages imprecise knowledge through approximate reasoning. The Introduction describes uncertainty and ambiguity in medical data. The paper studies Alzheimer’s disease, however, and does not establish that uncertainty and vagueness are common characteristics of psychiatric data specifically. (LLM, conf=0.84)

  • When combined with Random Forests, fuzzy logic can enhance model performance without sacrificing interpretability.

    “When combined with Random Forests, an ensemble-based machine learning method known for handling non-linear relationships and high-dimensional data, fuzzy logic can enhance model performance without sacrificing interpretability”

    From A hybrid fuzzy logic–Random Forest model to predict psychiatric treatment order outcomes: an interpretable tool for legal decision support (2025) · cites this paper as Shoaip et al., 2024

    In 'Experiment and results > Comparison with other machine learning systems' (page unavailable), the paper reports that its fuzzy inference system performed better than RandomForest on the ADNI dataset. It evaluates them as separate systems, however, and does not show that combining fuzzy logic with Random Forests improves performance or preserves interpretability. (LLM, conf=0.78)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
