Spreading the Word:

Spreading the word, broadening perspectives

Globalisation is ambivalent. On the one hand, it brings prosperity, comfort and convenience in the form of economic growth, technological advancement, more open and democratic governance, and so forth. On the other hand, there are vast amounts of casualties from its progress, which only benefits some groups or countries. Non-Government Organisations (NGOs) in Indonesia have established themselv...

Spreading the Word: Geography, Policy and Knowledge Spillovers

Using new data on citations to university patents and scienti…c publications, we study how geography a¤ects university knowledge spillovers. Citations to patents decline sharply with distance up to about 150 miles and are strongly constrained by state borders. Distance also constrains citations to scienti…c publications, but the impact is less sharp and persists over greater distances. The stat...

Spreading the Word: Geography, Policy and University Knowledge Diffusion

Using new data on citations to university patents and scientific publications, and measures of distance based on Google maps, we study how geography affects university knowledge diffusion. We show that knowledge flows from patents are localized in two respects: they decline sharply with distance up to about 100 miles, and they are strongly constrained by state borders, controlling for distance....

Word Sense Disambiguation with Spreading Activation Networks Generated from Thesauri

Most word sense disambiguation (WSD) methods require large quantities of manually annotated training data and/or do not exploit fully the semantic relations of thesauri. We propose a new unsupervised WSD algorithm, which is based on generating Spreading Activation Networks (SANs) from the senses of a thesaurus and the relations between them. A new method of assigning weights to the networks’ li...
