[1] CLAMOUR is a European collaborative project which aims to find a better way to classify when collecting and disseminating industrial information and statistics.
[2] Techniques for probabilistic weighting of single word terms date back to at least 1976 in the landmark publication by Stephen E. Robertson and Karen Spärck Jones.
[4] In 2004, Anna Lynn Patterson filed patents on "phrase-based searching in an information retrieval system"[5] to which Google subsequently acquired the rights.
Statistical compound-term processing is also more adaptable than the linguistic approach taken by the CLAMOUR project, which must consider the syntactic properties of the terms (i.e. part of speech, gender, number, etc.)
Compound-term processing allows information-retrieval applications, such as search engines, to perform their matching on the basis of multi-word concepts, rather than on single words in isolation which can be highly ambiguous.
