I wanted to find out what the most common first author is in that long list of articles, and this is what I did:
cat refs-2009+.txt | \ sed -e '/^ *$/d' -e 's/^- //' | \ cut -d"(" -f1 | \ cut -d, -f1 | \ cut -d' ' -f1 | \ sort | \ uniq -c | \ sort -r > \ sorted-refs.txt |
The result is this:
6 Craglia 4 Wang 4 Rajabifard 4 Onsrud 4 Masser 4 Grus 4 Crompvoets 3 Yang 3 Steiniger 3 Gartner 3 European 3 Anselin 2 Wright 2 Smits 2 Sieber 2 Ramsey 2 Poore 2 Miller 2 Lance 2 INSPIRE 2 Helly 2 Georgiadou 2 Fox 2 Foster 2 Bregt 1 Zhang 1 World ... |
