    R
    Fouh, Eric; Poirel, Christopher L. (2010-11-25)
    This module covers use of the R language for performing the statistical analysis needed for several information retrieval (IR) techniques. The R language is extremely extensive and a powerful tool. R will not be covered completely in this module. Rather, we hope to introduce some of the more common tools used in IR, such as matrix and vector manipulations.

    This module covers the use of a thesaurus in several information retrieval (IR) techniques: index construction (e.g., tokenization, stemming, and lemmatization), robustness to query typographical errors (e.g., the use of wildcard queries) and query refinement and expansion.
