Load Alessandro Vespignani's ISI publication history from 'using 'File > Load' and following this path: 'yoursci2directory/sampledata/scientometrics/isi/AlessandroVespignani.isi'using'File > Load' and select 'ISI scholarly format' in the pop-up window.

This analysis will detect the "bursty" terms used in the title of papers in the dataset. Since the burst detection algorithm is case-sensitive, it is necessary to normalize the field to be analyzed before running the algorithm. Select the table "101 Unique ISI Records" and run 'Preprocessing > Topical > Lowercase, Tokenize, Stem, and Stopword Text.' Check the "Title" box to indicate that you want to normalize this field:

...

In the Sci2 Tool, the algorithm can be found under 'Analysis > Temporal >Burst Detection'. As the algorithm itself is case sensitive, care must be taken if the user desires 'KOREA' and 'korea' and 'Korea' to be identified as the same word.

2. Add column headers for all years, i.e., enter first start year in G1, here 1980. Continue, e.g., using formulae formula '=G1+1', until highest burst end year, here 2004 in cell AE1.
