Pseudo-Relevance Feedback (PRF) is a well-known method of query expansion for improving the performance of information retrieval systems. All the terms of PRF documents are not important for expanding the user query. Therefore selection of proper expansion term is very important for improving system performance. Individual query expansion terms selection methods have been widely investigated fo...
When building a predictive model for predicting clinical outcome using machine learning techniques, the developers are often interested in ranking features according to their ability. A commonly used approach obtain robust variable is apply recursive feature elimination (RFE) on multiple resamplings of training set and then aggregate results Borda count method. However, presence highly correlat...
This paper considers the communication complexity of approximating common voting rules. Both upper and lower bounds are presented. For n voters and m alternatives, it is shown that for all ∈ (0, 1), the communication complexity of obtaining a 1− approximation to Borda is O(log( 1 )nm). A lower bound of Ω(nm) is provided for fixed small values of . The communication complexity of computing the t...
* We thank József Mala for posing the question of Nash implementability on restricted domains that led to this research. We are very grateful to two anonymous referees and an associate editor for their helpful comments and suggestions. The second author gratefully acknowledges financial support from the Hungarian Academy of Sciences (MTA) through the Bolyai János research fellowship. Summary. W...
This paper presents experiments analyzing the strategic behavior of voters under three voting systems: plurality rule, approval voting, and the Borda count. Strategic behavior is significantly different under each treatment (voting system). Plurality rule leads voters to play in a more sophisticated manner, but not necessarily insincerely, displaying the lowest levels of manipulation. The oppos...
Petroleum is an essential resource for the development of society and its production is huge. There is a great risk of leakage of oil during production, refining, and transportation. After entering the environment, the oil pollutants will be a great threat to the environment and may endanger human health. Therefore, it is very important to remediate oil pollution in the subsurface. However, it ...
We analyze a simple sequential algorithm (SA) for allocating indivisible items that are strictly ranked by n ≥ 2 players. It yields at least one Pareto-optimal allocation which, when n = 2, is envy-free unless no envy-free allocation exists. However, an SA allocation may not be maximin or Borda maximin—maximize the minimum rank, or the Borda score, of the items received by a player. Although SA...
This paper describes the participation of the SNUMedinfo team at the TREC Clinical Decision Support track 2014. This task is about medical casebased retrieval. Case description is used as query text. Per each query, one of three categories (Diagnosis, Test and Treatment) is designated as target information need. Firstly, we used external tagged knowledge-based query expansion method for the rel...
In response to the work of Borges et al. (2012), Hulkower (2012) poses questions regarding the relative merits of the Condorcet and the Borda methods; a topic which has been taking place in socio-political studies for a very long time. While both approaches have their supporters and their detractors (Young, 1988; Risse, 2005; Saari, 2006), below we present the reasons for choosing Condorcet’s m...
