A web-based shared document repository includes recommender system functions to allow users of the repository to input reviews of documents contained in the repository and to read inputted reviews. The recommender system functions appear as a seamless integration in the document repository by loosely coupling the shared document repository to a web-based recommender system.

Shared document repository with coupled recommender system

A method of searching for information in a text database, comprising: receiving (s1) at least one user input, the user input(s) defining a natural language expression, converting (s2, s3) the natural language expression to a tagged form (,) including part-of-speech tags, applying (s4) to the tagged form (,) one or more grammar rules of the language of the natural language expression (,), to derive a regular expression (,), and analyzing (s5) the text database to determine whether there is a match between said regular expression (,) and a portion of said text database. An apparatus for carrying out this techniques is also disclosed. Users may find portions of a text which match multiword expressions given by the user. Matches include possible variations that are relevant with the initial criteria from a linguistic point of view including simple inflections like plural/singular, masculine/feminine or conjugated verbs and even more complex variations like the insertion of additional adjectives, adverbs, etc. in between the words specified by the user.
