WebA local alignment finds the best matching subset of the two documents. This function adapts the Smith-Waterman algorithm, used for genetic sequencing, for use with natural language. It compare the texts word by word (the comparison is case-insensitive) and scores them according to a set of parameters. WebLocal Alignment Smith-Waterman Algorithm • We need to keep track of whether a zero arises from a calculation or from the choice of the fourth case. The zero is needed for as a default max score, but using ‘0’ as a place-marker on the grid is confusing. Might consider a different symbol, say, *, as a place-marker on the trace-back grid •
