- Summary::
- Increased word [ambiguity]([[ambiguity]]
-  (p. 891)
-  (p. 892, Table 2)
- Note: this effect was ~order of magnitude smaller than effects of number of disciplines and subject-wide modularity
- **Grounding Context**
- sample: ~1.1M abstracts from Web of Science (after trimming for min. threshold citations, and at least 5 usable terms for ambiguity measure in abstract)
-  (p. 880 - 881)
- [[ambiguity]]
- define as posterior distribution over pr(M | t, c) (probability of each possible meaning for a given token in a given context) - see Appendix A (how to build \"meaning graph\" for each token), and Appendix B (how to estimate ambiguity)
- very similar to [[LDA]]
-  (p. 898)
- 
- meaning simplified to proxy into synonyms from Moby and WordNet thesauri
- would prefer to define as cliques in synonym graph, but... for reasons, decided to simplify to just directed edges + the neighborhood
- examples (from data)
- 
-  (p. 885)
- validated against human judgments (see Appendix C)
- \"engagement\" operationalized as graph entropy over subgraph from each article for max (1k cites, 3 recursive runs), computed in terms of maximal [[network modularity]]
- toy example:
- 
-  (p. 880)
- examples (from data):
- 
- network modularity correlated at -.76 with topological entropy for random sample of 1.2k abstracts
