The tagger consists of three main modules: a preprocessor with multitagger and compound analyser (ref3), a grammar module for morphological and syntactic disambiguation (Constraint Grammar) (ref2) and a statistical module that removes the last of the remaining morphological ambiguity (only for Bokm\u00e5l). The Constraint Grammar module uses a compiler developed at the University of Southern Denmark in Odense. The multitagger uses the lexicon Norsk ordbank.<\/description>obt<\/resourceShortName>http:\/\/www.tekstlab.uio.no\/obt-ny\/english\/index.html<\/url>http:\/\/hdl.handle.net\/11538\/0000-0005-E7C6-7<\/PID><\/identificationInfo>Public<\/userCategory>downloadable<\/distributionAccessMedium>https:\/\/github.com\/noklesta\/The-Oslo-Bergen-Tagger<\/downloadLocation>GNU<\/licenceFamily>General Public License (GPL)<\/licenceName>http:\/\/www.gnu.org\/licenses\/gpl.html<\/licenceURL>BY<\/conditionsOfUse>SA<\/conditionsOfUse><\/licence>organization<\/actorType>University of Oslo<\/organizationName>Universitetet i Oslo<\/organizationName>UiO<\/organizationShortName>UoO<\/organizationShortName>Department of Linguistics and Scandinavian Studies<\/departmentName>Institutt for lingvistiske og nordiske studier (ILN)<\/departmentName><\/organizationInfo>tekstlab-post@iln.uio.no<\/email>http:\/\/www.hf.uio.no\/iln\/om\/organisasjon\/tekstlab\/<\/url><\/p>\n

0317<\/zipCode>OSLO<\/city>Norway<\/country><\/communicationInfo><\/actorInfo><\/metadataCreator><\/metadataInfo>true<\/validated>Bokm\u00e5l: The evaluation of the morphological constraint grammar modul shows a success rate (recall) of 99% and a precision of 96%. This gives an f-measure of 97.5% (if recall and precision are weighted equally).<\/p>\n

The tagger was tested on a 30 000 words long evaluation corpus with texts from newspapers, magazines, journals, government reports and novels.<\/p>\n

Including the statistical module to perform complete disambiguation of the evaluation corpus yields a tagger accuracy of 96.5%. This number includes both fully disambiguation of morphology and lemma.<\/p>\n

Nynorsk: Evaluation is so far only made for the original CG1-module of the Oslo-Bergen tagger. This module had a success rate (recall) of 98.7% with 93.6% precision. This gives an f-measure of 96.2%.<\/p>\n

The evaluation corpus for Nynorsk also had about 30 000 words taken from newspapers, magazines, journals, government reports and novels.<\/validationModeDetails>validationReport<\/role>See in publications:
