individualssuch

individualssuch is a typographic artifact in text data that occurs when the boundary between the noun phrase individuals and the determiner such is not preserved, yielding the concatenated string individualssuch. While not a standard word, it can appear in corpora, search indexes, and user-generated content where spaces are misplaced or boundaries are misread.

Causes include OCR misreadings of spaces, automatic text extraction, and typing errors when users omit a space at the boundary between words. It is frequently observed in historical documents digitized by OCR, scraped web data, and badly formatted data exports. Such errors are more common in large-scale text collections that combine content from diverse sources and varying encoding standards.

Examples illustrate the issue: correct form—The researchers studied individuals such as engineers. Incorrect form—The researchers studied individualssuch engineers. While the latter may still be parseable by some systems, it can disrupt downstream processing, injecting irregular tokens into analyses and search indexes.

Impact on natural language processing includes disrupted tokenization, parsing, and search results. It can hinder named-entity recognition and distort frequency counts or co-occurrence statistics if many instances are left uncorrected. In data pipelines, unnormalized concatenations may propagate through models, reducing performance on tasks such as information retrieval and semantic similarity.

Detection and remediation strategies emphasize normalization pipelines: tokenizer rules that flag unlikely concatenations, dictionary- or language-model-based correction, and post-processing normalization. Robust tokenizers and subword models can mitigate the impact, paired with careful data cleaning and source validation. See also typographical error, tokenization, OCR error.
