Spatiotemporal recommendation in geo-social networks
No full textHome Location: A user’s home location is the place where the user is living. It is a static location instead of a real-time location that is “temporally” related to the user (e.g., the places where the user is visiting) LBSNs: Location-based social networks Out-of-Town Recommendation: If the distance between the target user’s current location and home location is larger than a threshold d (say 100 km), the spatial item recommendation problem is defined as out-of-town recommendation; otherwise, the problem is hometown recommendation POI: Point of interest Spatial Item: A spatial item is an item associated with a geographical location (e.g., a restaurant or a cinema),….</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Simplifying the Formulation of a Wide Range of Object-Oriented Complex Queries
No full textWe present a model that simplifies the formulation of a wide range of complex, mainly selection-based, object-oriented queries, including linear recursive queries. They are complex because it is almost impossible for naive users to predict the formulation of their predicate expressions. Naive users are mainly decision makers who are most probably not computer professionals. Therefore, it is necessary to provide them with a straightforward and easy-to-handle approach to retrieve the information required for the decision making process. To achieve this, the definition of the selection operation and the predicate definition are adjusted to make it possible to have in the output only a subset of the objects from the actual result of a linear recursive query. Otherwise, it is infeasible to achieve the same output without an additional selection with a complicated predicate. We also define an operation that facilitates applying aggregate functions on objects. The two operations proved to be very useful and necessary to study the characteristics of trees and directed graphs. The presented model has been implemented as a part of our object-oriented database management system prototype.</p
