Lexical Computing

What Lexical Computing does

Lexical Computing, founded in 2003 and headquartered in Portslade, United Kingdom (with an operating entity in the Czech Republic), builds and sells large-scale linguistic data assets and the tooling to use them. Its core technology is a proprietary pipeline that collects and cleans authentic web text to construct text corpora totaling 1 trillion words across 100+ languages, with the largest English corpus at 90 billion words. From these corpora the company generates enriched products — word frequency lists, n-gram (bigram, trigram and larger) databases, and word databases/lexicons containing millions of unique items per language with POS tags, lemmas, probabilities, synonyms, collocations, example sentences, and morphological information. The company positions these datasets as inputs for language modeling (LLMs), NLP applications, and corpus-based research.

The commercial portfolio spans three categories. Self-serve software tools — Sketch Engine (corpus query and management), Lexonomy (online dictionary editor), OneClick Terms (terminology extraction), and Lexicom (a course in lexicography) — operate on a subscription/recurring basis with free trials. Downloadable data products — word frequency lists, n-gram databases, and enriched word databases — are sold as one-time perpetual licenses, starting at EUR 250 for academic/research use and EUR 2,500 for commercial use, with custom quotations for large or specialized enterprise databases. The third layer is bespoke professional services covering terminology extraction, document classification, data mining, information retrieval, and custom corpus generation, sold via direct quotation.

The company sells horizontally to three primary buyer types: (i) software developers and AI/NLP practitioners needing reliable, large-scale language data; (ii) dictionary and language-teaching publishers needing lexical databases and frequency information; and (iii) enterprise teams needing language processing solutions for content management. Distribution is exclusively digital — a self-serve website with sample downloads, free trial accounts, custom-quotation enterprise sales, and presence on LinkedIn, Facebook, X, LinkedIn groups, and Academia.edu. The company operates globally with no geographic restrictions disclosed, is privately held with no institutional funding on record, and maintains a small team (11-50 employees).

Others

• Linguistic Data Consortium (LDC): LDC is the leading North American distributor of linguistic corpora, lexicons, and annotations to academic and government buyers; it is a distribution-side peer serving the same corpus linguistics and NLP research customers.
• Common Crawl Foundation: Common Crawl provides open, petabyte-scale web crawl data that many LLM teams use directly as a training corpus; it is the closest open-data alternative to Lexical Computing's cleaned text corpora and shapes market expectations on data pricing.
• ELRA (European Language Resources Association): ELRA / ELDA is the principal European distributor and consortium for language resources including corpora and lexica; it operates in the same buyer ecosystem as Lexical Computing and overlaps on European-language data licensing.

Broad incumbents

• Hugging Face: Hugging Face operates a broad hub for NLP models and datasets including pre-built corpora and language data; it overlaps with Lexical Computing in NLP data distribution and dictionary/lexicon-adjacent assets, but at vastly larger scale and broader scope.
• MemoQ / SDL Trados: MemoQ and SDL Trados are leading translation environment tools that include terminology management and translation memory features, overlapping with OneClick Terms and Lexonomy for dictionary and terminology workflows used by translators and language service providers.

Direct peers

• CQPweb: CQPweb, from Lancaster University, is a self-hosted corpus query system using the IMS Open Corpus Workbench; it is a direct technical peer for Sketch Engine in academic corpus linguistics deployments.
• AntConc: Laurence Anthony's AntConc is a free, widely used desktop corpus toolkit providing concordances, word lists, and n-gram analysis; it competes head-to-head with Sketch Engine for academic and corpus linguistics users and constrains pricing in that segment.
• LancsBox: LancsBox is Lancaster's modern successor desktop corpus toolkit with corpus building, annotation, and analysis features; it competes with Sketch Engine across the same corpus linguistics workflow.
• WordSmith Tools: Mike Scott's WordSmith Tools is a long-standing paid corpus analysis toolkit offering word frequency lists, concordances, and keyword analytics — a near-direct functional peer to Sketch Engine for the same lexicographer and corpus linguist buyer.
• Voyant Tools: Voyant Tools is a web-based, open-source text analysis environment for corpus reading and exploration; developed in the same digital humanities and corpus linguistics tradition, it overlaps directly with Sketch Engine's web-delivered analytical use cases.
