Methods and apparatus for identifying associated key words (1035) in a data set (1000). Associated key words are identified by a parser (1020) which firstly operates to extract key words from a data set (1000). These key words are then analysed by the parser (1020) to identify which key words, if any, have an association as determined by a predefined set of rules. These rules are grammatical and include, for example, two keywords both being nouns that occur one after the other without intervening low value words. A similar rule applies to nouns followed by verbs but does not extend to verbs followed by nouns. These rules allow terms and phrases such as "information technology" and "wide area network" to be identified as associated key words (1035) rather than as individual and unrelated key words.

L'invention concerne des procédés et des appareils d'identification de mots clés associés (1035) dans un ensemble de données (1000). Les mots clés associés sont identifiés par un analyseur (1020) qui, tout d'abord, extrait des mots clés d'un ensemble de données (1000). Ces mots clés sont ensuite analysés par l'analyseur (1020) pour identifier quels mots clés, s'il y en a, présentent une association telle que déterminée par un ensemble de règles prédéfinies. Ces règles qui sont grammaticales comprennent, par exemple, deux mots clés, tous deux étant des noms survenant l'un après l'autre sans interposition de mots de faible valeur. Une règle similaire s'applique aux noms suivis de verbes, mais ne s'applique pas aux verbes suivis de noms. Ces règles permettent d'identifier des termes et des syntagmes, tels que "information technology" ("technologie de l'information") et "wide area network" ("réseau étendu"), comme mots clés associés (1035) plutôt que comme mots clés individuels et distincts.
