I need to build a python program that reads a set of txt files (some gutenberg files) and then use NLTK library to tokenize, normalize stem, remove stop words, and then building an inverted index for all tokens in all files. An inverted index is a mapping of words to their location in a set of documents. Most modern search engines utilize some form of an inverted index to process user-submitted queries. In its most basic form, an inverted index is a simple hash table which maps words in the documents to some sort of document identifier.

Visit Stack Exchange When building an inverted index, it can be useful to resolve related strings to a common root. For example, in a corpus relating to animals it might be useful to derive a singular noun for each animal; as a result, documents containing either the word dog or dogs could be found under the index entry dog . (Well, I tried, but they were slower than my Python code and/or crashed a lot because I haven't figured out Cython well enough.) I could run on top of Jython and use Lucene's inverted index as a library, except that my other chemistry code is built on C/C++. Or I could gulp down the PyLucene, which includes the Java runtime.

Here, we assume that the first 3 steps have already been done, and we examine building a basic inverted index by sort-based indexing . \begin{figure} %
