TREX supports several other languages for which restrictions currently apply as regards TREX functionality. TREX currently supports the following additional languages with restrictions (May 2006/external software version 3.7.3):
For a detailed description of how to activate these additional languages, seeConfiguring Language Recognition.
Certain restrictions apply because the linguistic processing development for these additional languages is still at a relatively early stage. TREX functions such as search, attribute query, query-based classification, and other functions that use text-mining functions rarely or never work at the same level of quality as for fully supported languages.
However, the linguistic text-mining functions sometimes delivery results of less quality that in the case for the fully supported languages. Results of poor quality can occur in the following areas:
Automatically calculated document and/or class features may be of poor quality.
When using this classification method the elements may be classified less precisely.
Incomplete or unexpected grammatical variations of a search term may be returned in the search results list.
