I am not sure if this is the right website to ask this question but I cant figure out where else to get the answer so, please, dont be mad :-)
As my bachelor thesis/project, I am trying to construct a short-scale search engine using TF-IDF measure. At the moment I am working on the construciton of my index. Usually term-document matrix is used where the rows represent terms (words) and columns are documents (webpages) on that pages. My question is - why is this better than using document-term matrix (this one would be just a transpostion of the term-document one.
It appears to me, that adding a new page to this matrix is more common operation and adding new row slightly easier than adding new column. I would be glad, if you could suggest me any article concerning this topic, because I have found none so far.
Thank you all your answers in advance!
