However, in the absence of specific pathology or task information, the few-shot examples suggest that datasets with insufficient information are labeled as 'Unknown' for all categories. This is based on the convention seen in datasets such as 'EEG: Probabilistic Learning with Affective Feedback: Exp #2,' where more detailed metadata guide the selection of labels.","metadata_analysis":"The metadata available is minimal, with only the title 'HID' and names of authors provided. There is no further information on the study population, task paradigms, or sensory stimuli used in the dataset. The readme is also overly simplistic, providing no additional context ('HID dataset').","paper_abstract_analysis":"No useful paper information is available. There is no abstract or external documentation provided that could clarify the purpose or design of the dataset.","evidence_alignment_check":"1. Pathology: Metadata says 'HID dataset' with no mention of specific clinical populations. Few-shot suggests 'Unknown' when no details are provided. They align on 'Unknown'. \n2. Modality: Metadata offers no insights, and few-shot suggests 'Unknown' when modality is unclear, aligning again on 'Unknown'. \n3. Type: With no task or cognitive constructs described, few-shot suggests 'Unknown', consistent with metadata's lack of detail.","decision_summary":"Top candidates for all categories are 'Unknown' based on the lack of specific, detailed information in the metadata. Both few-shot examples, which suggest labeling unknown parameters as 'Unknown', and the metadata analysis strongly align in this decision. Thus, each category is marked 'Unknown' with a confidence of 0.4, reflecting the lack of substantive information and alignment with few-shot conventions."}},"nemar_citation_count":0,"computed_title":"HID","nchans_counts":[{"val":72,"count":66}],"sfreq_counts":[{"val":2048.0,"count":66}],"stats_computed_at":"2026-05-31T19:34:32.600061+00:00","total_duration_s":66630.77978515625,"canonical_name":null,"name_confidence":0.97,"name_meta":{"suggested_at":"2026-04-14T10:18:35.343Z","model":"openai/gpt-5.2 + openai/gpt-5.4-mini + deterministic_fallback"},"name_source":"canonical","author_year":"Johnson2023_HID","bad_channels_info":null,"generated_by":[{"Name":"bids-matlab-tools","Version":"8.0"}],"references_and_links":[""]}}
