Tilde provides languages of the Baltic countries with intelligent language technologies that are equivalent to the support available for major world’s languages, using a combination of statistical and knowledge-driven approaches.
Verifies the spelling of every word, and offers to replace the misspelled word with the correct one. It automatically changes words that are unambiguously misspelled. Tilde’s team constantly improves the spelling checker by including new lexical items and by adding new features (e.g. Intelligent AutoCorrect). Now Latvian and Lithuanian spelling checker recognizes more than 22 million forms generated from more than 130 thousand lemmas.
Verifies the sentence structure and punctuation. Tilde's developed grammar checker is based on syntactic analysis of the text which offers to correct the most common grammar mistakes, including agreement between words, punctuation error at the end of a sentence, comma errors in insertions, comma errors in participial phrase, comma errors in equal parts of sentence, comma error in sub clause, as well as stylistic errors. It also allows the program to find long distance syntactical errors between different sub parts of the sentence. In addition, calques, slang and some other undesirable words or language construction usage are identified. This module also corrects such simple errors as extra spaces before or after punctuation marks, no equal number of opening and closing brackets, quotation marks, etc.
Tilde also has developed a hyphenation tool for Latvian and Lithuanian. Hyphenator puts all the possible hyphens in the Latvian and Lithuanian words in the text. For hyphenation, both rules defining the usual hyphenation process and exception list (words which cannot be hyphenated using just rules) are used.
The spelling checker and the grammar checker are a part of Tildes Birojs and Tildes Biuras PC Suite and works in Microsoft Word, OpenOffice and LibreOfficeWriter text editors.
