Exploring family relations between international patent applications

Exploring the Patent Explosion1

This paper looks more closely at the sources of patent growth in the United States since 1984. It confirms that the increase is largely due to US patenters, with an earlier surge in Asia, and some increase in Europe. I find that growth has taken place in all technologies, but not in all industries, being concentrated in the electrical technology-based industries (electrical, electronics, comput...

Extraction of Family Relations between Entities

Nowadays, there is a growing need to automatically extract information from texts. In this active research field much effort has been invested to improve the identification and classification of named entities, the detection of time expressions, and the identification of semantic relations between text entities. This paper presents a system that identifies and classifies family relations. The d...

Event Count Models for International Relations: Generalizations and Applications

International relations theorists tend to think in terms of continuous processes. Yet we observe only discrete events, such as wars or alliances, and summarize them in terms of the frequency of occurrence. As such, most empirical analyses in international relations are based on event count variables. Unfortunately, analysts have generally relied on statistical techniques that were designed for ...
