Stemmingalgorithm : computational procedure that will reduce all the inflectional derivational variants of words to a common form called the stem Removingall or some of the affixes attached to the word. Example : group,groups,grouped group Introduction (whatisstemmingAlgorithm?)
developed based on Rules Application Order (RAO) approach. • adding a few appropriate affixes into the list of rules, • modifications of the spelling variations rules • adding a few missing words into the dictionary of root • sorting in decreasing order according to the frequency of rule’s usage in previous stemming. Introduction ( Whatis RFO? )
PREFIX + + SUFFIX PREFIX + SUFFIX +INFIX+ Rules FORMATS

Experiment ( RAOvsRAO2vsnraovsrfo ) • Test 1 = pr – ps – su – in • Test 2 = pr – su – ps – in • Test 3 = ps - pr – su – in • Test 4 = ps – su – pr – in • Test 5 = su – pr – ps – in • Test 6 = su – ps – pr – in • Test 7 = alphabetical Legend : pr = Prefix ps = Prefix – Suffix su = Suffix in = Infix alphabetical = thealphabeticalorder of all rules
SpellingException ( Recoding ) Prefixes Suffix * Samplenotation rules : Men + c, d, sy, t, z
RFO Evaluation • CompressionAchived • Reduce Error • RFO is an improvement because it returns less distinct words and higher compression percentage • RFO also recorded the least amount of errors
Summary • From the experiments performed, it is found that : • - The order of rules to use is not necessary to follow any order of affixes types. • Let the rules sorted in alphabetical order for the first pass, and for the second pass, sort the rules according to usage frequency of each rule. • - Experiments showed that the new approaches in stemming are better than other Malay stemmer as RAO by Ahmad.
