Identifying temporal relations between main events in new articles

Ines Berrazega, Rim Faiz
2013 2013 ACS International Conference on Computer Systems and Applications (AICCSA)  
In this concern, processing the temporal dimension of language and extracting temporal information from electronic news articles is becoming a prominent task.  ...  Our approach is based on a complete linguistic analysis of texts and supervised learning models.  ...  In fact the attributes which are directly obtained from the tags of the labeled contents have a great impact on the performance of temporal relation identification.  ...

A survey on question answering technology from an information retrieval perspective

Oleksandr Kolomiyets, Marie-Francine Moens
2011 Information Sciences  
On the one hand, natural language queries are reduced to keyword-based searches, on the other hand, knowledge bases are queried with structured or logical queries obtained from the natural language questions  ...  We discuss different levels of processing yielding bag-of-words-based and more complex representations integrating part-of-speech tags, classification of the expected answer type, semantic roles, discourse  ...  We refer to the sections on answer type recognition and semantic role labelling for a discussion of the classification algorithms.  ...

Understanding the Semantic Structure of Noun Phrase Queries

Xiao Li
2010 Annual Meeting of the Association for Computational Linguistics  
We present methods that automatically identify these constituents as well as their semantic roles based on Markov and semi-Markov conditional random fields.  ...  Determining the semantic intent of web queries not only involves identifying their semantic class, which is a primary focus of previous works, but also understanding their semantic structure.  ...  The role of IMs is to imposing constraints on the attributes of an intent class.  ...

A Computational Cognitive Model for Semantic Sub-Network Extraction from Natural Language Queries

Suman Deb Roy, Wenjun Zeng
2012 International Conference on Computational Linguistics  
Semantic query sub-network is the representation of a natural language query as a graph of semantically connected words.  ...  In this paper, we present a novel standalone NLP technique that leverages the cognitive psychology notion of semantic forms for semantic subnetwork extraction from natural language queries.  ...  Natural languages are undeniably imprecise, especially in the realm of semantics. The primary reason of this imprecision is the fuzziness of class boundaries (Zadeh, 1998) .  ...

Machine Learning for Automatic Labeling of Frames and Frame Elements in Text

Martin Scaiano
2011 International Journal of Linguistics  
The development of systems that extract a frame representation of text can lead to deeper semantics being used in natural language processing.  ...  We present the development of our system for extracting frames from text. Our system is trained on the FrameNet data and tested on the SemEval 2007: Task 19 Frame Extraction Task data.  ...  Future work based on this system will likely involve testing it on tasks such as entailment, question answering, novelty detection (detection of novel or new information) and other reasoning-based tasks  ...
