Sample text

59% (58+333 / 665) of equal query pairs had overlap while 49% (82+313 / 802) of different query pairs had some overlapping messages. The small difference between these figures could be an artefact of the way people search for emails and the properties of email collections themselves. e. the number of messages clicked per query is much larger. 17 message clicks compared to the 1 or less page clicks associated with SE queries [16]. Secondly, email collections are of course much smaller than the web, which naturally increases the chance of serendipitous overlap.

New movie releases for online rental). In general, template-based models improve the recall achieved by whitelists by about 20%. From the model size perspective, the compressed template models are consistently smaller than the respective whitelists. However, even the compressed model sizes range from hundreds to tens of thousands of templates. Therefore, it is virtually impossible to anticipate (and manually craft) query patterns for a specific use case, especially if high recall levels are desired.

3 Overlapping Clicks with Different Queries A final situation of interest in Table 2 is when there was overlap in clicks, but the queries were not the same (cells 4 and 5). Examining these queries however, reveals that although the queries were not the same, often they were very similar. Examples of query pairs for chains where message overlap is high (overlap coefficient >75% 4 ), but queries do not match include:“mar”/“maria”, “jen”/“jennifer”, “virt”/“virtual”, “lisa”/“lisa nathan”, “johnston”/“david joh”5 .
