Cross-lingual knowledge extraction

Knowledge extraction has been a challenge for many years and it remains a challenge. On this long path of exploring language and simultaneously modeling the world, we have transitioned through many stages. From the early years, when linguists were exploring the structure of words and sentences, and philosophers were discussing ontology, up till today, when a large part of written information is available to almost everybody and modern communication allows researchers to join their efforts and exploit opportunities offered by technology. Still, the apparent opportunities seem to be much bigger than the actual depth of the solutions developed in recent years in the field of text understanding. One of the key properties of natural languages is redundancy in the encoded information and the structure used. As a consequence, different techniques can extract different aspects of information from a text. They range …
