Changes are reviewed before they are made available on the live site.ĪCM will expand this edit facility to accommodate more types of data and facilitate ease of community participation with appropriate safeguards. An author's photograph, a Home Page URL, and an email may be added, deleted or edited. The initial release of the Author Edit Screen is open to anyone in the community with an ACM account, but it is limited to personal information. For a definition of ACM's first set of publication statistics, see Bibliometrics With ACM's first cut at author name normalization in place, the distribution of our authors with 1, 2, 3.n publications does not match Lotka's Law precisely, but neither is the distribution curve far off. According to this bibliometric law of scientific productivity, only a very small percentage (~6%) of authors in a field will produce more than 10 articles while the majority (perhaps 60%) will have but a single article published.

Bibliometrics: In 1926, Alfred Lotka formulated his power law (known as Lotka's Law) describing the frequency of publication by authors in a given field.

ACM is meeting this challenge, continuing to work to improve the automated merges by tweaking the weighting of the evidence in light of experience.

Hence it is clear that manual intervention based on human knowledge is required to perfect algorithmic results. With very common family names, typical in Asia, more liberal algorithms result in mistaken merges.Īutomatic normalization of author names is not exact. Many bibliographic records have only author initials. The more conservative the merging algorithms, the more bits of evidence are required before a merge is made, resulting in greater precision but lower recall of works for a given Author Profile.

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.
