By detecting the consumer’s “center of interest” and matching it with the product’s “characteristics” (attributes tag), some recommenders are able to amaze the

In this paper, we have presented a parsing method which is based on a precise linguistic description and which can be applied to tagged texts as well

In fact, most of us (and I include myself here) have done rather worse than that – in that having identified the need to think beyond growth we have then reverted to the more

First introduced by Faddeev and Kashaev [7, 9], the quantum dilogarithm G b (x) and its variants S b (x) and g b (x) play a crucial role in the study of positive representations

Example results are (i) the mean and variance of the number of (possibly overlapping) ordered labeled subgraphs of a labeled graph as a function of its randomness deficiency (how far

However in our approach, we have achieved a real time processing using initialization scheme with OR-PCA, moreover image decomposition together with continuous contraint improves

In VADA [21], all of format transformation, source selection, matching, mapping and data repair are informed by evidence in the form of the data context [20], instance values that

The key idea is that we collect meta- data about the attributes in the database (e.g., attribute data type), meta-data about the feature generative functions (e.g., id of the
