This paper describes the approaches and results of our system for the NTCIR-10 INTENT task. We present some methods for Subtopic Mining subtask and Document Ranking subtask. In the Subtopic Mining subtask, we employ a voting method to rank candidate subtopics and semantic resource HowNet was used to merge those candidate subtopics which may impact diversity. In the Document Ranking Subtask, we ...

Van Raan et al. (2010) accepted our critique for the case of journal normalization (previously CPP/JCSm); CWTS has in the meantime adapted its procedures. However, a new indicator was proposed for field normalization (previously CPP/FCSm), called the “mean normalized citation score” (MNCS; cf. Lundberg, 2007). In our opinion, this latter change does not sufficiently resolve the problems. Since ...

The recent concept of ‘‘Health Insurance Marketplace’’ introduced to facilitate the purchase of health insurance by comparing different insurance plans in terms of price, coverage benefits, and quality designates a key role to the health insurance providers. Currently, the web based tools available to search for health insurance plans are deficient in offering personalized recommendations based...

Nowadays, most of e-service portals focus on individual users rather than considering shared characteristics that could be useful when searching a portal. Service providers searching activities involve different types of common user behaviors and preferences that should be considered. Thus, group profiling can be used to group customers with similar interests together and recommend service prov...

With the increasing deployment of functionally similar web services by different service providers, nonfunctional aspects, which are often referred to Quality of Service (QoS), play a vital role in ranking web services. Various users may have different priorities of QoS attributes. However, ordinary users are lacking in the ability to map their plain requirements to the obscure technical QoS me...

Let S be a dataset of n 2-dimensional points. The top-k dominating query aims to report the k points that dominate the most points in S . A point p dominates a point q iff all coordinates of p are smaller than or equal to those of q and at least one of them is strictly smaller. The top-k dominating query combines the dominance concept of maxima queries with the ranking function of top-k queries...

This paper introduces a qualitative ranking function that uses signed integers to describe the surprise associated with the occurrence of events. The measure introduced, κ, is based on the κ calculus but differs from it in that its semantics enable an explicit representation of complements. As a result, the κ is more capable of enforcing probability theory-like constraints to carry on reasoning.

This paper describes our participation in the Intent Mining track of NTCIR-11. We present our methods and results for both document ranking and subtopic mining. Our ranking methods are based on several data fusion techniques with some variations. Our subtopic mining method is a very simple technique that uses query dimensions’ items to form a subtopic

sweden and spain experiment with different provider models to reform healthcare provision. both models have in common that they extend the role of the for-profit sector in healthcare. as the analysis of saltman and duran demonstrates, privatisation is an ambiguous and contested strategy that is used for quite different purposes. in our comment, we emphasize that their analysis leaves questions ...
