Online annotation of text streams with structured entities

Ken Q. Pu, Oktie Hassanzadeh, Richard Drake, Renée J. Miller
2010 Proceedings of the 19th ACM international conference on Information and knowledge management - CIKM '10  
We propose a framework and algorithm for annotating unbounded text streams with entities of a structured database.  ...  Our algorithm does so with a guarantee of constant time and space complexity for each additional word in the text stream, thus infinite text streams can be annotated.  ...  CONCLUSION AND FUTURE WORK We have presented an online entity annotation algorithm which correlates an unbounded text stream with databases of entities by means of non-deterministic annotation.  ...

The Birth of Collective Memories: Analyzing Emerging Entities in Text Streams [article]

David Graus, Daan Odijk, Maarten de Rijke
2017 arXiv   pre-print
The online text streams we use for our analysis comprise of social media and news streams, and span over 579 million documents in a timespan of 18 months.  ...  Specifically, we analyze nearly 80,000 entities as they emerge in online text streams before they are incorporated into Wikipedia.  ...  All content represents the opinion of the authors, which is not necessarily shared or endorsed by their respective employers and/or sponsors.  ...

Processing online news streams for large-scale semantic analysis

Milos Krstajic, Florian Mansmann, Andreas Stoffel, Martin Atkinson, Daniel A. Keim
2010 2010 IEEE 26th International Conference on Data Engineering Workshops (ICDEW 2010)  
In this paper, the semantic analysis of such news streams is discussed by introducing a system that streams online news collected by the Europe Media Monitor to our proposed semantic news analysis system  ...  To demonstrate the use of our system, the case studies show a) temporal analysis of entities, such as institutions or persons, and b) their co-occurence in news articles.  ...  ACKNOWLEDGEMENTS This work was partially funded by the German Research Society (DFG) under grant GK-1042, "Explorative Analysis and Visualization of Large Information Spaces".  ...

Pattern-Based Annotation of HTML-Streams [chapter]

Florian Schmedding, Max Schwaibold, Kai Simon
2009 Lecture Notes in Computer Science  
In this paper, we demonstrate Atheris, a system that annotates structured web pages by means of our web data extraction tool ViPER.  ...  Web pages containing RDFa markup facilitate a broad range of new agents that improve their usability for human readers. Unfortunately, there still exist only few web sites featuring such annotations.  ...  The purpose of these rules is the automatic labeling of named entities, the splitting of strings, and the removal of text from data entities to simplify further rule assignments.  ...

Making sense of social media streams through semantics: A survey

Kalina Bontcheva, Dominic Rout
2014 Semantic Web Journal  
Unlike carefully authored news text and longer web context, social media streams pose a number of new challenges, due to their large-scale, short, noisy, contextdependent, and dynamic nature.  ...  This paper defines five key research questions in this new application area, examined through a survey of state-of-the-art approaches for mining semantics from social media streams; user, network, and  ...  The authors wish to thank Marta Sabou and Arno Scharl for the discussions on crowdsourcing and its role in semantic technologies research, as well as Diana Maynard for the discussions on opinion mining of  ...

Interactive Knowledge Base Population [article]

Travis Wolfe, Mark Dredze, James Mayfield, Paul McNamee, Craig Harman, Tim Finin, Benjamin Van Durme
2015 arXiv   pre-print
Most work on building knowledge bases has focused on collecting entities and facts from as large a collection of documents as possible.  ...  We argue for and describe a new paradigm where the focus is on a high-recall extraction over a small collection of documents under the supervision of a human expert, that we call Interactive Knowledge  ...  In the small text collection paradigm, asking a user for a fairly complete annotation of the entities and proposition expressed in text is feasible, and system output can be vetted by an expert.  ...

2020 arXiv   pre-print
With respect to the recent outbreak of COVID-19, online discourse on Twitter reflects public opinion and perception related to the pandemic itself as well as mitigating measures and their societal impact  ...  However, obtaining, archiving and semantically annotating large amounts of tweets is costly.  ...  Some datasets contain only information filtered from raw twitter stream data, for instance, to extract subsets of relevance to particular events 24 while others include annotations, such as mentioned entities  ...
