Create feature identification API

Create a disambiguation profile API

Mockup

Business need

Certain profiled users have features that aren't properly captured in an identity source. This is especially true for users on our periphery such as alumni and residents. For example, ReCiter doesn't perform well for Harold Varmus, because we have no record in a source system for his time at NIH. We would like to give users the opportunity to assert additional characteristics of themselves and have that be used to improve accuracy.

With an API, we can display features in an external interface and ask users to accept or reject these features.

Note that this output would need to occur against the output of the feature generator. It would also require doing a query against the Identity table. The building of the feedback interface would go in a separate issue.

Process

1. Compute and score the suggested articles for a given person.

2. From the computed articles in the Analysis output where score is greater than the minimum threshold for storing articles and the article is not rejected, identify any of the following features.

a. Institutional affiliations (Scopus Author ID and label)
b. Organizational units (label)
- Look up org units in the ScienceMetrixJournalDepartmentCategory.primaryDepartment field using one of the following against affiliation:
- "Department of " + [primaryDepartment]
- "Division of " + [primaryDepartment]
- "Dept of " + [primaryDepartment]
- any of the other patterns defined in org unit matching
- Look for patterns from org unit synonyms
- Some org units in ScienceMetrixJournalDepartmentCategory are substrings of each other. Match to longest unit if possible.

c. Aliases of target author

• Sanitize names using standard function
• Identify cases where targetAuthor=TRUE and name is not:
  • listed among existing names in aliases or primary name.
  • first name is not one initial, or 2-3 initials all capitals
• Dedupe substrings. Prefer longer versions.

d. Aliases of non-target authors

• Sanitize names using standard function
• Identify cases where targetAuthor=FALSE and name is not:
  • listed among existing names in aliases or primary name.
  • first name is not one initial, or 2-3 initials all capitals
• Dedupe substrings. Prefer longer versions.
• CWID shouldn’t be required for importing additional relationships

e. Email address(es)

• Identify email addresses of target author
• See issue: Output email even if it's not a match #322

f. ORCID identifier(s)

• Identify ORCID ID of target author
• See issue: Identify ORCID identifier for each author #336

3. Compute a score for each feature

• Generally speaking, we want to prioritize features associated with high scoring articles.
• We create arrays for each of the above, e.g., {emails: [email protected], [email protected]...}
• Count the number of each, e.g., for [email protected], n=3
• For each distinct feature, multiply the average score of the candidate articles associated with that feature times the count raised to some constant N, e.g., 3 x ((8.1 + 12.2 + 13.1)/3)^N
• N is averageArticleScore-DisambiguationExponent. Default is 1.5.

4. Determine status of each feature

• Options are:
  • assertedInSystemOfRecord (e.g., determine if feature is already located in Identity table)
  • accepted
  • rejected
  • null

5. Output features

   "uid":"paa2013",
   "emails":[  
      {  
         "email":"[email protected]",
         "status":"accepted",
         "score":53.2
      },
      {  
         "email":"[email protected]",
         "status":"assertedInSystemOfRecord",
         "score":31.7

Some examples where this would be helpful.

For Harold Varmus, co-author = Peter Vogt.

Institutional affiliation = UCSF and department = Microbiology & Immunology
