The article "CohEEL: Coherent and Efficient Named Entity Linking through Random Walks" by Toni Gruetze (HPI), Gjergji Kasneci (Schufa),  Zhe Zuo (HPI) and Felix Naumann (HPI) was accepted for publication at the JWS special issue on Knowledge Graphs.

Abstract:

In recent years, the ever-growing amount of documents on the Web as well as in digital libraries led to a considerable increase of valuable textual information about entities. Harvesting entity knowledge from these large text collections is a major challenge. It requires the linkage of textual mentions within the documents with their real-world entities. This process is called entity linking.  

This project aims at the automatic creation of entity links from texts to a knowledge base. In contrast to recent research that usually balances the rate of linking correctness (precision) and the linking coverage rate (recall), this project focuses on creating reliable links by favoring the linking precision. Linking precision is the decisive factor for subsequent tasks, building upon the linking results, such as, text summarization, document classification, or topic-based clustering.
