Classification: CPC G | IPC G

Claim 14:
15. A method for searching for information in a set of digital data in a computer and/or computer network or a database, comprising the following steps:
receiving a search term;
assessing the search term as a function of a shift in meaning of the search term with respect to a second text collection; and
as a function of the assessment, carrying out the search using the search term or rejecting the search term;
wherein the shift in meaning is determined by:
providing a first text collection;
providing the second text collection that is different from the first text collection;
ascertaining a first vector space model that characterizes a first vector space associated with the first text collection;
ascertaining a second vector space model that characterizes a second vector space associated with the second text collection;
ascertaining a modified second vector space model as a function of a mapping of the second vector space onto the first vector space; and
analyzing the search term as a function of a first word vector of the first vector space model corresponding to the search term, and as a function of a second word vector of the modified second vector space model corresponding to the search term;
wherein the analysis includes ascertainment of a first variable that characterizes a vector distance between the first word vector and the second word vector, the first variable representing the shift in meaning of the search term from the second text collection, to a domain associated with the first text collection.
