Named Entity Recognition for Hindi-English Code-Mixed Social Media Text

Named Entity Recognition (NER) is a major task in the field of Natural Language Processing (NLP), and also is a sub-task of Information Extraction. The challenge of NER for tweets lie in the insufficient information avai…

A Practical Incremental Learning Framework For Sparse Entity Extraction

This work addresses challenges arising from extracting entities from textual data, including the high cost of data annotation, model accuracy, selecting appropriate evaluation criteria, and the overall quality of annotat…

Neural Disease Named Entity Extraction with Character-based BiLSTM+CRF in Japanese Medical Text

We propose an 'end-to-end' character-based recurrent neural network that extracts disease named entities from a Japanese medical text and simultaneously judges its modality as either positive or negative; i.e., the menti…

Comparing Constraints for Taxonomic Organization

Building a taxonomy from the ground up involves several sub-tasks: selecting terms to include, predicting semantic relations between terms, and selecting a subset of relational instances to keep, given constraints on the…

SystemT: Declarative Text Understanding for Enterprise

The rise of enterprise applications over unstructured and semi-structured documents poses new challenges to text understanding systems across multiple dimensions. We present SystemT, a declarative text understanding syst…

ELISA-EDL: A Cross-lingual Entity Extraction, Linking and Localization System

We demonstrate ELISA-EDL, a state-of-the-art re-trainable system to extract entity mentions from low-resource languages, link them to external English knowledge bases, and visualize locations related to disaster topics o…

End-to-end named entity extraction from speech

Named entity recognition (NER) is among SLU tasks that usually extract semantic information from textual documents. Until now, NER from speech is made through a pipeline process that consists in processing first an autom…

Construction of the Literature Graph in Semantic Scholar

We describe a deployed scalable system for organizing published scientific literature into a heterogeneous graph to facilitate algorithmic manipulation and discovery. The resulting literature graph consists of more than …

A Deep Neural Network based Approach for Entity Extraction in Code-Mixed Indian Social Media Text

Linking, Searching, and Visualizing Entities in Wikipedia

Tracking the Diffusion of Named Entities

Existing studies of how information diffuses across social networks have thus far concentrated on analysing and recovering the spread of deterministic innovations such as URLs, hashtags, and group membership. However inv…

Morphology-based Entity and Relational Entity Extraction Framework for Arabic

Rule-based techniques to extract relational entities from documents allow users to specify desired entities with natural language questions, finite state automata, regular expressions and structured query language. They …

Language-based Construction of Explorable News Graphs for Journalists

Faced with ever-growing news archives, media professionals are in need of advanced tools to explore the information surrounding specific events. This problem is most commonly answered by browsing news datasets, going fro…

A Feature-based Ensemble Approach to Recognition of Emerging and Rare Named Entities

Detecting previously unseen named entities in text is a challenging task. The paper describes how three initial classifier models were built using Conditional Random Fields (CRFs), Support Vector Machines (SVMs) and a Lo…

Multi-entity sentiment analysis using entity-level feature extraction and word embeddings approach

The sentiment analysis task has been traditionally divided into lexicon or machine learning approaches, but recently the use of word embeddings methods have emerged, that provide powerful algorithms to allow semantic und…

LIMSI-COT at SemEval-2017 Task 12: Neural Architecture for Temporal Information Extraction from Clinical Narratives

In this paper we present our participation to SemEval 2017 Task 12. We used a neural network based approach for entity and temporal relation extraction, and experimented with two domain adaptation strategies. We achieved…

An End-to-end Environment for Research Question-Driven Entity Extraction and Network Analysis

This paper presents an approach to extract co-occurrence networks from literary texts. It is a deliberate decision not to aim for a fully automatic pipeline, as the literary research questions need to guide both the defi…

Lexical Correction of Polish Twitter Political Data

Language processing architectures are often evaluated in near-to-perfect conditions with respect to processed content. The tools which perform sufficiently well on electronic press, books and other type of non-interactiv…

Demonstration of interactive teaching for end-to-end dialog control with hybrid code networks

This is a demonstration of interactive teaching for practical end-to-end dialog systems driven by a recurrent neural network. In this approach, a developer teaches the network by interacting with the system and providing…

Information-Theory Interpretation of the Skip-Gram Negative-Sampling Objective Function

In this paper we define a measure of dependency between two random variables, based on the Jensen-Shannon (JS) divergence between their joint distribution and the product of their marginal distributions. Then, we show th…
