keywords: names in common whose works address the same subject matter as determined from title and keywords, weigh toward being the same person.publication title: names in common whose works are published in same journal weighs toward the two names being the same person.

affiliations: names in common with same affiliation weighs toward the two names being the same person.If so, this weighs towards the two names being the same person. co-authors: if we have two names and cannot disambiguate them based on name alone, then we see if they have a co-author in common.Normalization: ACM uses normalization algorithms to weigh several types of evidence for merging and splitting names.The Author Profile Pages reveal the first result of these efforts. For the past several years, ACM has worked to normalize author names, expand reference capture, and gather detailed usage statistics, all intended to provide the community with a robust set of publication metrics.

Of equal importance to ACM, author name normalization is also one critical prerequisite to building accurate citation and download statistics.

History: Disambiguation of author names is of course required for precise identification of all the works, and only those works, by a unique individual.

Please see the following 2007 Turing Award winners' profiles as examples: Over time, the contents of the Author Profile page may expand at the direction of the community. The Author Profile Page supplies a quick snapshot of an author's contribution to the field and some rudimentary measures of influence upon it. Coverage of other publishers generally starts in the mid 1980's. Coverage of ACM publications is comprehensive from the 1950's.

Description: The Author Profile Page initially collects all the professional information known about authors from the publications record as known by the ACM bibliographic database, the Guide.
