Some e-shops present product attributes in structured form, but many others use the textual description only. Attributes of products are essential in automated product deduplication. We suggest methods for automated extraction of attributes and their values from product descriptions to a structural form. The structural data extracted from other e-shops are used as background knowledge.

This note is a resume of Jerry Hausman’s Nake course at the NAKE workshop in Den Haag, The Netherlands in June 2002. It presents an intuitive framework in which the impact of weak/invalid instruments on properties of di¤erent estimators can be analyzed while also suggesting a test to detect the presence of weak/invalid instruments.

detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. this distribution could be detected by different geophysical methods, especially gravity method. however, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. performance of the gravity technique co...

Binocular rivalry entails a perceptual alternation between incompatible stimuli presented to the two eyes. A minimal explanation for binocular rivalry involves strong competitive inhibition between neurons responding to different monocular stimuli to preclude simultaneous activity in the two groups. In addition, strong self-adaptation of dominant neurons is necessary to enable suppressed neuron...
