Physicists, stamp collectors, human mobility forecasters

One of the two reviewers studied in high school to be a physicist. In the end, he became something else, but he never lost his awe of physics. The other reviewer never intended to become a physicist, but he sometimes asks himself why he didn’t become one. Today, they are both sociologists who practice their science on an action theory basis and believe that regularities exist in the world of social actions which can be perceived, understood, explained – and even used for making predictions

Data exploration systems for databases

Data exploration systems apply machine learning techniques, multivariate statistical methods, information theory, and database theory to databases to identify significant relationships among the data and summarize information. The result of applying data exploration systems should be a better understanding of the structure of the data and a perspective of the data enabling an analyst to form hypotheses for interpreting the data. This paper argues that data exploration systems need a minimum amount of domain knowledge to guide both the statistical strategy and the interpretation of the resulting patterns discovered by these systems

Supporting collaborative information retrieval in the virtual library

The advent of the virtual library is usually presented as a welcome development for library users. Unfortunately, this tends to reinforce the perception of the use of information resources as a solitary activity. In fact, as many studies have emphasised, information retrieval (IR) in the conventional library is often a highly collaborative activity, involving users' peers and experts such as librarians. Failure to take this into account in the design of virtual library services may result in its users being disadvantaged and denied timely and effective access to sources of assistance. Our focus here is on collaboration between users and librarians. We report an investigation of collaboration issues as seen from the perspective of librarians' and users' contexts and encapsulated in the notion of genre. Finally, we describe the design of a pilot multimedia-based system intended to support collaboration between librarians and IR system users
