Using TF-IDF to Determine Word Relevance in Document Queries : In this paper, we examine the results of applying Term Frequency Inverse Document Frequency (TF-IDF) to determine what words in a corpus of documents might be more favorable to use in a query. As the term implies, TF-IDF calculates values for each word in a document through an inverse proportion of the frequency of the word in a particular document to the percentage of documents the word appears in. Words with high TF-IDF numbers imply a strong relationship with the document they appear in, suggesting that if that word were to appear in a query, the document could be of interest to the user. We provide evidence that this simple algorithm efficiently categorizes relevant words that can enhance query retri

3D PLOT USING MATLAB IN PSCAD WARNING * This case only works if you use the Compaq/Intel Fortran Compiler. A T_D_PLOT component. It provides the interface to a MATLAB function t_d_plot . It is a user-defined function and the m-file T_D_plot.m contains its definition. This component plots a 3-dimensional curve. Input: X, Y and Z values of the point to be plot Output: a dummy output of value zero Parameters of T_D_PLOT component.
