Constraints

Because the linguistic processing development for these additional languages is still at a relatively early stage, certain restrictions apply. 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:

·        Feature extraction

Automatically calculated document and/or class features may be of poor quality.

·        Example-based classification

When using this classification method the elements may be classified less precisely.

·        Linguistic search

Incomplete or unexpected grammatical variations of a search term may be returned in the search results list.
