Reliable high-quality frequency lists

We are providers of high-quality word frequency lists (also called dictionaries or lexicons) in many languages. The lists are generated from an enormous authentic database of text (text corpora) produced by real users of the language. Our corpora in some languages contain texts with a total length of as many as 40,000,000,000 words.

Wordlist quality

A relatively small corpus is sufficient to generate a list of the 2,000 most frequent words, or a lexicon of 3,000 words or 5,000 words because such words appear frequently enough in any text.

An enormous text database (corpus) is required to ensure reliable word frequency information even for rare and infrequently used words. The only viable option of building corpora of billions of words is using an automatic procedure of downloading content from the web. Lexical Computing developed a sophisticated procedure for collecting only linguistically valuable content from the web. A series of tools is used to focus on the right content and to perform deduplication and cleaning. This ensures that the statistics are not skewed. This blog post gives more details.

Wordlist size

We are able to generate frequency lists of millions of unique words. The actual size depends on the specifications. By default, we will not include any word which appears fewer than 5 times in the corpus. Such words are typically noise without any linguistic value. The client can specify any filtering options.

Enriched frequency wordlists

We are also able to provide lexicons with additional information such as POS tags, lemmas, probabilities of the next word, or any other statistics or morphological information.

Sample data

The easiest is to register a free trial account in Sketch Engine and use the wordlist tool to generate a wordlist or a lexicon to your specifications. The advanced tab of the wordlist tool allows for detailed specifications to be used.

Prices

We will provide a quotation based on the exact specifications of the dictionary or lexicon and its intended use.

Download

The lexicon will be made available for download on a dedicated link within the agreed period of time. It normally takes a week or two to generate the data. Very complex wordlists can be computationally demanding and can take longer to produce.
