Although Hu man codes are easily docoded left-to-right, their use is awkward on most machines The facilities for handling characters are often much better than bit-oriented operations Schemes to use free characters to replace frequent long strings can be easy and e ective Both unassigned and unused control and data characters can be free Table 14-2 shows that especially 8-bit codes, bytes, have many free characters It is possible that about 150 of these character codes will not occur in the text Since blank sequences are frequent, some, say 4, free characters can be assigned to represent two blanks, three blanks, four blanks, or eight blanks If other characters are expected to occur in long sequences, this technique can be extended to those characters If many of the characters are apt to be repeated, the free characters can be used to indicate two, three, four, or eight repetitions of the preceding character If certain words appear with great frequency, they can also be replaced by single free characters Which words occur most frequently in a text depends greatly on the universe of discourse Words such as THE OF A TO AND IN THAT IS IT FOR ON ARE are universally frequent, and hence are, in general, candidates for replacement by single character codes In natural text, unfortunately, the shortest words occur already with the greatest frequency A rule, Zipf s law provides an estimate for the relationship between frequency and size in many situations If n words wi , i = 1 n are listed in

the order of their size, from smallest to largest, we can expect that their frequency of occurrence f r(wi ) will be f r(w1 ) = c/1, f r(w2 ) = c/2, f r(w3 ) = c/3, , f r(wn ) = c/n 14-2

where or Euler s constant is 05772 One can consider replacing longer but yet frequent words by shorter multiple letter combinations, in a sense intensifying Zipf s law by inclusion of unpronounceable combinations In a stored database textbook the replacement of database by db could be pro table The lexicons required to e ect this translation can become quite large This approach has been used in les of names Zipf s law can also be applied to estimate the progression of the type-token ratio for words in a text, ranked according to their frequency of occurrence, or individual type-token ratio Knuth73S shows how a better t to Zipf s law can be obtained by adding a parameter to the divisor in the sequence, so that f r(itemi) = c i1 14-4

With = 01386 the sequence expresses Heising s 80-20 rule stated in Sec 6-1-6, and with = 00 the sequence expresses the type-token ratio for the words from the text by Schwartz63 used for Table 14-5 for the words ranked from 5 to 4000 Extremely high and low frequencies do not quite match Since (as discussed in Sec 14-2-3) a limited number of last names of individuals accounts for many of the names in les [SSA57 ], it is possible to replace these names by shorter representations These short names can be made up out of the 20 consonants, giving, for instance, 8000 three-consonant combinations for more than half the names in use Use of two letters and a digit in an arbitrary position of the representation would avoid the rare but possible confusion with an existing name and provide 20 280 combinations, beginning with 1AA and ending with ZZ9 The names with extremely high frequency can be represented by combinations of two characters, 1A to Z9 Lexicons to control replacement of names or words can be generated by analysis of the le or of a sample of the le If a xed- eld encoding is desirable, some of the codes can be used to refer to an over ow le for names which could not be encoded A format Zaa, for instance, could use the digits aa to point to records containing unencodable names

Dynamic Replacement If adequate processor time at data-entry time is available, the selection of a lexicon to control replacement can be done dynamically The lexicon which is speci c to a record now has to be carried along with the record An example from DeMaine71 is shown in Fig 14-4
