Abstract

A method and apparatus for identifying important terms in a sample text. A frequency of occurrence of terms in the sample text (sample frequency) is compared to a frequency of occurrence of those terms in a reference text (reference frequency). Terms occurring with higher frequency in the sample text than in the reference text are considered important to the sample text. A difference between the respective sample and reference frequencies of a term may be used to determine an importance score. Terms can be ranked and/or added to an affinity set as a function of importance score or rank. When there are insufficient terms for determining a sample frequency, those terms may be used in a search query to identify documents for use as sample text to determine sample frequencies. The important terms may be used for document summarization, query refinement, cross-language translation, and cross-language query expansion.
