About Scholar H-Index Calculator
Scholar H-Index Calculator (the Calculator from now on) is an addon for Firefox which enhances Google Scholar results pages by showing a number of bibliometric data computed using the data appearing on video as input.
Once installed, the Calculator works transparently when querying Google Scholar: as soon as you make a query, result pages are enriched with a number of useful data (e.g. the h-index computed on the basis of displayed data), and new functions are available.

Documentation and examples
Custom formula editing
As of Calculator 3.0, there is the possibility for users to add their own bibliometric formulas and display their outcome next to default indices. There are two types of custom formulas: Normalizations and Indices.
Normalizations
In the Calculator information box, each row shows bibliometric indices depending on a given Normalization. Each normalization weighs citations of each paper depending on a given criterion. Three are the default normalizations:
'none' : no normalization. The normalized citations of a paper corresponds to those displayed (after subtracting self citations). Same as the custom formula citations-selfCitations
'by authors': the citations of each paper are normalized by the (estimated) number of authors. Same as the custom formula (citations-selfCitations)/authors. For instance a paper with 100 citations and 4 authors, will score a number of normalized citations of 25. The number of authors cannot be always estimated correctly unless the refinement function is used. You might want to read the Author Refinement section about how the Calculator estimates the number of authors per each paper.
'by age': if paper i has been cited t times, and has been written in 2001, its number of normalized citations per age is t/(CY-2001+1), for CY the current year. Same as the custom formula (citations-selfCitations)/(year-thisYear+1). As an example, a paper scoring 100 citations and written in 2003, would score 10 normalized citations.
You can add your own normalization formulas by clicking on the button 'New normalization' on the bottom of the Information box.
You should enable the Advanced interface first.
