1Lee, W.M. ; Sanderson, M.: Analyzing URL queries.
In: Journal of the American Society for Information Science and Technology. 61(2010) no.11, S.2300-2310.
Abstract: This study investigated a relatively unexamined query type, queries composed of URLs. The extent, variation, and user click-through behavior was examined to determine the intent behind URL queries. The study made use of a search log from which URL queries were identified and selected for both qualitative and quantitative analyses. It was found that URL queries accounted for ?17% of the sample. There were statistically significant differences between URL queries and non-URL queries in the following attributes: mean query length; mean number of tokens per query; and mean number of clicks per query. Users issuing such queries clicked on fewer result list items higher up the ranking compared to non-URL queries. Classification indicated that nearly 86% of queries were navigational in intent with informational and transactional queries representing about 7% of URL queries each. This is in contrast to past research that suggested that URL queries were 100% navigational. The conclusions of this study are that URL queries are relatively common and that simply returning the page that matches a user's URL is not an optimal strategy.
2Lee, W.M.: Publication trends of doctoral students in three fields from 1965-1995.
In: Journal of the American Society for Information Science. 51(2000) no.2, S.139-144.
Abstract: This study investigates the publication rates of successful doctoral students in the fields of analytical chemistry, experimental psychology, and American literature. Publication rates were calculated for a sample of those receiving doctorates every fifth year between 1965 and 1995. an analysis of the data revealed that there were differences in publication rates of the doctoral students that mirrored differences between the fields as a whole. The data also show that the decline in solo authorship observed in many fields is present in this population as well. Participation rates (percent that had at least one publication) for chemistry and literature showed initial increases followed by plateaus since the early 1980s, while the participation rate in psychology has remained between 40 and 60 % over the course of the study
