Abstract: A method for measuring technology trends that includes providing from a plurality of inventors in a technology field a baseline of technical documents published in a time period, and detecting a number of technical document publications having at least one inventor in the plurality of inventors in the technology field. The method further includes comparing the number of technical document publications to the baseline of technical documents published in the time period. If the technical document publications exceed the baseline, the number of technical document publications are trending. Comparative analysis of the content for the technical document publications that are trending determines a measurement of similarity in technical field subgroups. Trending technical subgroups are extracted from the technical document publications that are trending with a degree of similarity above a threshold as a target technical group that is a trend.

Abstract: A method, a computer system, and a computer program product for determining an expertness level for a target keyword. The method includes preparing a document set associated with the target keyword, identifying, for each document in the document set, a category to which the document in the document set belongs, and determining an expertness level for the target keyword, based on a degree of dispersion of the identified categories. Each document in the document set may be associated with a category, and a graph which defines relations among the identified categories is generated from the identified categories to obtain the degree of dispersion of the identified categories. On condition that the degree of dispersion is lower, the expertness level for the target keyword may be determined to be higher or a higher expertness level is assigned to the target keyword.

A first server computes a correlation among the first measurement values based on the first measurement values. A proxy computes an actual measurement value of a second measurement value based on the first measurement values and a given function.
