Semantic Information Extraction for Improved Word Embeddings
Semantic Information Extraction Improved Word Embeddings
2016/1/22
Word embeddings have recently proven useful in a number of different applications that deal with natural language. Such embeddings suc-cinctly reflect semantic similarities between words based on thei...
Lights, Camera, Action: Knowledge Extraction from Movie Scripts
Activity Knowledge Commonsense Knowledge Acquisition
2016/1/22
With the success of large knowledge graphs, research on automat-ically acquiring commonsense knowledge is revived. One kind of knowledge that has not received attention is that of human activi-ties. T...
Beyond information extraction:The role of ontology in military report processing
ontology information extraction military report ontological process information visualization
2015/7/30
Information extraction tools like SMES transform natural language into formal representation, e.g. into feature structures. Doing so, these tools exploit and apply linguistic knowledge about the synta...
Extraction of Buildings in Brasilian Urban Environments Using High Resolution Remote Sensing Imagery and Laser Scanner Data
Laser scanner Quickbird Classification.
2015/7/7
The paper describes the resulst of recent experiments of a project that deals with the combined use of high resolution satellite
images, Quickbrid, and laser scanner data to analyse urban images. The...
The reconstruction of 3D city models has matured to the point where large data sets are now available. As most of the data collection
methods used are based on airborne sensors like e.g. aerial laser...
Entity-based Enrichment for Information Extraction and Retrieval
Information Retrieval Information Extraction Search Search Engines Knowledge Base
2014/12/18
The goal of this work is to leverage cross-document entity relationships for improved understanding of queries and documents. We define an entity to be a thing or concept that exists in the world, suc...
Information Extraction (IE) is the name given to any process which selectively structures and combines data which is found, explicitly stated or implied, in one or more texts. The final output of the ...
