Query-Dependent Contextualization of Streaming Data
[chapter]
2014
Lecture Notes in Computer Science
Preserved Fulltext
We propose a method for linking entities in a stream of short textual documents that takes into account context both inside a document and inside the history of documents seen so far. ...
Our results demonstrate the effectiveness of combining entity ranking functions that take into account context, which is further boosted by 6% when we use an informed global control function. ...
We propose a query-dependent contextualization approach tailored for streaming text. ...
