  • Is Oprah Contagious? Identifying Demand Spillovers in Online Networks

    ICIS 2009 Honorable Mention; NET Institute Working Paper

    We study the spread of exogenous demand shocks generated by book reviews featured on the Oprah Winfrey TV show and published in the New York Times through the online co-purchase recommendation network on Amazon.com. We leverage the co-purchase recommendation network on Amazon.com to determine how such exogenous events might affect the demand for books that were not explicitly mentioned in a review but are located “close” to reviewed books in a product network. Our results show that the demand…

    We study the spread of exogenous demand shocks generated by book reviews featured on the Oprah Winfrey TV show and published in the New York Times through the online co-purchase recommendation network on Amazon.com. We leverage the co-purchase recommendation network on Amazon.com to determine how such exogenous events might affect the demand for books that were not explicitly mentioned in a review but are located “close” to reviewed books in a product network. Our results show that the demand shock diffuses to books that are up to three links away from the reviewed book. However, the magnitude of diffusion varies widely across books at the same network distance from reviewed products. We also describe how product characteristics, assortative mixing and network properties can explain this variation in the depth of contagion. We discuss the significance of these results and their implications for the design of networks of products as well as for optimizing digital marketing spillovers.

  • Resolution enhancement in MRI

    Magnetic resonance imaging

    We consider the problem of Super Resolution Reconstruction (SRR) in MRI. Sub-pixel shifted MR Images were taken in several fields of view to reconstruct a high-resolution image. A novel algorithm is presented. The algorithm can be applied locally and guarantees perfect reconstruction in the absence of noise. Results that demonstrate resolution improvement are given for phantom studies (Mathematical Model) as well as for MRI studies of a phantom carried out with a GE clinical scanner. The method…

A novel algorithm is presented. The algorithm can be applied locally and guarantees perfect reconstruction in the absence of noise. Results that demonstrate resolution improvement are given for phantom studies (Mathematical Model) as well as for MRI studies of a phantom carried out with a GE clinical scanner. The method raises questions that are discussed in the last section of the paper. Open questions should be answered in order to apply this method for clinical purposes.

  • Assessing Value in an Online Network of Products

    ICIS 2012 Best Paper Award; To appear in Journal of Marketing, May 2013

    Traditionally, the value of a product is assessed according to its direct revenues. However, products do not exist in isolation but rather influence one another's sales. Such influence is especially evident in eCommerce environments, where products are presented as a large-scale product network. We present the first attempt to use a systematic approach to estimate products' true value to a firm in such settings. We separate a product’s value into its own intrinsic value, the value it receives…

    Traditionally, the value of a product is assessed according to its direct revenues. However, products do not exist in isolation but rather influence one another's sales. Such influence is especially evident in eCommerce environments, where products are presented as a large-scale product network. We present the first attempt to use a systematic approach to estimate products' true value to a firm in such settings. We separate a product’s value into its own intrinsic value, the value it receives from the network, and the value it contributes to the network. Using data from the network of books on Amazon, we examine the relationship between revenue and the sources of value. We show that the value of low-sellers is underestimated when focusing on direct revenue, while the value of bestsellers is overestimated. We explore the sources of this discrepancy and discuss the implications for managing products in an environment of product networks.

  • Reconciling data

    Issued USPTO

    Methods, systems, and apparatus, including computer program products, are described for reconciling data. In one implementation, a method includes generating co-occurrence scores indicating whether data in entries in a first source of data co-occur within documents in a plurality of documents with data in entries in a second source of data. The co-occurrence scores for a given entry in the first source of data are used to identify a plurality of candidate matching entries in the second source…

In one implementation, a method includes generating co-occurrence scores indicating whether data in entries in a first source of data co-occur within documents in a plurality of documents with data in entries in a second source of data. The co-occurrence scores for a given entry in the first source of data are used to identify a plurality of candidate matching entries in the second source of data for the given entry. Data in fields in the given entry are compared to that of one or more of the candidate matching entries to produce field similarity scores. The field similarity scores and the co-occurrence scores are used to determine a match for the given entry among the plurality of candidate matching entries.
