Count

Start      Previous      Next  

The next phase is to count the unresolved person (URPs) matches and the unresolved organizations (UROs). To do this we apply the transforms  countURPs.xsl  and countUROs.xsl . Figure 9 shows the more complex URP case. The URO case is much simpler since organizations are compared based on a single string.

  • [F9H0] Notice that this transform outputs text not XML.
  • [F9H1] This code builds up a variable  gcCount  that contains a sequence of integers each of which represents the number of distinct names/netids in each group formed by name parts. This will also include names without  NETID s in the source. The grouping order used here does not handle the case of name variants with the same netid in the same result set. Such cases can arise because of change of marital status which is not easily distinguished, in an automated way, from other cases such as a mistyped netid. Any such problems can be fixed by post processing to correct any misattributions based on common netid. Changing the grouping order (i.e. by netid then name parts) also works but with additional coding complexity. Note that we are only interested in  EduRecords  where the personURI  is empty those are the URPs in  ED0.xml .
    • [F9H1a] Collect all nodes in the current group formed by grouping by name parts and then group them by  nid  (the tag we use in  ED0.xml  to represent a source  NETID ). The variable  gp  refers to this sequence of nodes.
    • [F9H1b] Count the nodes in each sub-group and append the count to the  cgCounts  sequence.
  • [F9H2] Output the grand total by summing the sequence  cgCounts . This is the number of distinct URPs found in  ED0.xml .


countURPs.xsl - Figure 9

In our example, we find 11 unresolved people URIs and 5 unresolved organization URIs. Next we will construct enough URIs to fill in the URPs and UROs.
