2. discuss Pool (Laura Agnew) communication networks
3. discuss citation analysis
Smith reading.
Citation assumptions
Citing implies author has used the document
Citation reflects merit of the doc
Citations are made to best works
Cited doc is related in content to citing work
If two documents ref lists both cite one or more docs, they are bibliographically coupled, implies content related
If two documents are cited in the same reference list, they are cocited, implies content related
All citations are equal
Problems of citation analysis
Multiple authors
Self-citations
Homographs (same name/different authors)
Synonyms (name variants)
Types of sources (books vs journals, some journals limit citations)
Implicit citations (discussed or implied but not cited)
Time fluctuations (year to year)
Field variations (e.g., humanities vs sciences)
Errors
Applications
Various literature studies
User studies
Historical studies
Communication patterns (e.g., how ideas spread)
IR (e.g., google, Clever today)
Collection development
Logical Assumptions (Griffith, Drott & Small)
1. X cited by Y is more likely to be related to Y than arbitrary A not cited
1. X cited by Y and A not cited by Y=>more likely that X was used in preparation of Y
2. Y and Z cite X=>more likely Y and Z are related than A and B citing no docs in common
3. Y cites X and Z=>X and Z more likely related to each other than to A not cited by Y (not co-cited with X and Y)
