would use if/else write algorithm in haskell? there way express without them? it's hard extract functions out of middle have meaning. output of machine learning system.
i'm implementing algorithm classifying segments of html content content or boilerplate described here. has weights hard coded.
curr_linkdensity <= 0.333333 | prev_linkdensity <= 0.555556 | | curr_numwords <= 16 | | | next_numwords <= 15 | | | | prev_numwords <= 4: boilerplate | | | | prev_numwords > 4: content | | | next_numwords > 15: content | | curr_numwords > 16: content | prev_linkdensity > 0.555556 | | curr_numwords <= 40 | | | next_numwords <= 17: boilerplate | | | next_numwords > 17: content | | curr_numwords > 40: content curr_linkdensity > 0.333333: boilerplate
since there 3 paths in decision tree leads boilerplate state, i'd iterate , simplify them:
isboilerplate = prev_linkdensity <= 0.555556 && curr_numwords <= 16 && prev_numwords <= 4 || prev_linkdensity > 0.555556 && curr_numwords <= 40 && next_numwords <= 17 || curr_linkdensity > 0.333333
