Information Retrieval in Search Engines Using Pseudo Relevance Feedback Mechanism
2019 International Conference on Vision Towards Emerging Trends in Communication and Networking (ViTECoN), 2019Online data generation is increasing rapidly due to technological development. In order to handle the huge volume of data, big data methodology is used widely. Though big data can able to process huge data, it has its own issues including information storage, data management, and retrieving data. In big data, data retrieval is an issue where the method

Partial channel information feedback mechanism for FFR-based multi-channel systems
The Journal of China Universities of Posts and Telecommunications, 2010Abstract This article puts forward a partial channel state information (CSI) feedback scheme for fractional frequency reuse (FFR)-based orthogonal frequency division multiple access (OFDMA) systems. Efficient CSI feedback strategy plays an important role in opportunistic scheduling because base station (BS) can employ adaptive modulation and coding ...

Multiversion information retrieval systems and feedback with mechanism of selection
Journal of the American Society for Information Science, 1993This article initiates a study of multiversion information retrieval (IR) systems. The term “multiversion” refers to the existence of several different methods for realizing one (as a minimum) system's process. The article also provides a theoretical justification for the necessity of creating such systems to perform an optimal search for the ...

User acceptance of complex electronic market mechanisms: Role of information feedback
Journal of Operations Management, 2013AbstractThis paper broadens the scope of evaluating the design of economic mechanisms that is traditionally done solely from an economic perspective. We introduce and demonstrate the application of acceptability to evaluate complex economic mechanisms.

A Hybrid Channel State Information Feedback Mechanism for Massive MIMO System
2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016In this paper, CSI feedback for massive MIMO system with planar antenna array is studied. A hybrid channel state information feedback mechanism is proposed. The proposed mechanism is based on combination of beamformed CSI-RS and non-beamformed CSI-RS transmission.

Feedback mechanisms as intermediaries for Web information market: an exploratory study
Proceedings of the 34th Annual Hawaii International Conference on System Sciences, 2005The Internet is sometimes said to be drowning in contents. Users of information therefore experience great difficulty in identifying the accuracy, relevancy and interpretability of information. Total data quality management and centralized information intermediaries are either too expensive for the vast amount of Internet contents or they force ...

In situations where information processing would exceed cognitive limitations or the decision is not considered important enough to justify higher effort investments, people apply heuristics to reduce the effort to invest in processing information at the cost of an increased error rate.

Research on Information Feedback Mechanism of Emergency Supplies Based on System Dynamics
ICLEM 2010, 2010The timely and accurate delivery of Emergency supplies is the key to Emergency Logistics activities. Based on system dynamics theory, the information feedback model about emergency supplies for disaster is established. By parameters controlling, like controlling on convection rate and the level, the exact quantity of emergency supplies can be provided.

The majority of reverse auctions for procurement use a single-attribute (price) format while providing constraints on nonprice attributes such as quality and lead time. Alternatively, a buyer could choose to conduct a multiattribute auction where bidders can specify both a price and levels of nonprice attributes.
