Base Claim:
1. A computer program product for comparing items of anonymized data, the computer program product comprising: one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising: program instructions to receive a plurality of items of data, each item of the plurality of items of data comprising an anonymized ordered list of words, wherein each word of the anonymized ordered list of words is anonymized in a plurality of forms and is associated with a respective item of data, wherein the plurality of forms comprise: a respective word of the anonymized ordered list of words as the respective word originally appeared, a variation of the respective word, and a metaphone encoding of the respective word; and program instructions to compare a first item of the plurality of items of data with a second item of the plurality of items of data by: comparing each of the plurality of forms of each word in the first item with the corresponding form of each corresponding word in the second item; scoring each comparison of each word in the first item with each respective word in the second item based on: a degree of matching between each of the plurality of forms of each word in the first item with the corresponding form of each corresponding word in the second item; a plurality of weights assigned to each corresponding form of the plurality of forms, wherein a first weight is assigned to the respective word of the anonymized ordered list of words as the respective word originally appeared, a second weight is assigned to the variation of the respective word, and a third weight is assigned to the metaphone encoding of the respective word; and wherein the first weight exceeds the second weight and the second weight exceeds the third weight; and computing a total score for the comparison of the first item and the second item based on the scoring.

Claim 4:
4. The computer program product of claim 1 , wherein program instructions to compute the total score are further based on a value associated with matching words, based on the degree of matching, between the first item and the second item, wherein the matching words are located in different positions in each respective ordered list of words of the first item and the second item.
