Table 3 Results of PDON evaluation based on expert questions. For both competency questions, PDON-driven search in SCAIView retrieved less number of abstracts than simple queries in PubMed but more relevant to the questions (i.e. less noise). This performance efficiency for the PDON-driven search has been calculated in percent as shown in the last column
Competency question number | Total no. of abstracts retrieved by PDON in SCAIView | No. of PDON-derived abstracts answering the questions | Total no. of abstracts retrieved by PubMed | No. of PubMed-derived abstracts answering the questions | PDON-driven retrieval efficiency (% PDON retrieval - % PubMed retrieval) |
|---|---|---|---|---|---|
1 | 70 | 20 | 95 | 20 | 28.7 %-21 %: 7.7 % |
2 | 6 | 5 | 3 | 1 | 83.3 %-33.3 %: 50 % |
