Workshops

 

A series of workshops will be held in conjunction with ESOLEC’19 to encourage the exchange of ideas and to discuss challenging research issues in NLP. Workshops will be held before the main conference on saturday 26-9-2020 and post the main conference on Tuesday 29-9-2020

 

Frist Workshop

Automatic Linguistic Analysis                     Bibliotheca Alexandrina, Alexandria, 26 September 2020

This workshop is concerned with the automatic linguistic analysis. It will be hands on applied linguists for who are interested in this field. It will be held at Bibliotheca Alexandrina and will be divided into Two sessions: the first one is Practices In Forensic Phonetics and Linguistics and the second one is Corpus analysis tools.

 

Session 1  A Journey Across Two Decades of Speaker Recognition

This workshop  will introduce the field of speaker recognition covering basic definitions, modalities and applications. We then move to different modeling techniques that were used in the past two decades presenting the basic principles and possible extensions. We provide popular toolkits and datasets for those who want to try these techniques in practice. We finally close by showing how speaker recognition systems are evaluated and provide some results from modern systems.

 

The invited speaker

Mohamed Afify is an  experienced researcher and engineering leader in the fields of speech recognition and natural language processing. In the past decade, I led teams of researchers and engineers at Orange and Microsoft to deliver real-world products and services in the areas of voice and multi-media services, Arabic speech recognition and machine translation, speaker authentication and language understanding. These products and services are currently in use by millions of customers of these companies. I contributed many novel ideas in these areas that were published in top conferences and journals. I also have a strong academic background where I was associate professor at Cairo University until 2004.

 

Session 2  Corpus analysis tools

1- Build an Arabic Part of speech (POS) tagging using Hidden Markov Model (HMM)

It aims to help audience to build a POS tagger for modern standard Arabic using HMM model . It will be hands on for linguists and engineers. The session's target is beginners mainly. It will cover:

  • Brief introduction to Part of Speech tagging (POS) .

The talk will illustrate what is part of speech tagging and its challenges in Arabic.

  • Introduction to Hidden Markov Model.

This part will introduce the hidden marcov model to the audience.

  • A hands-on implementation of the part of speech tagging using HMM

           This part will show audience how to build the pos tagger using python and sklearn.

  • Test the built model to find out its accuracy.

2- Build your Parser in ten minutes.

It aims to help audience to build a probabilistic context free grammar parser . It will be hands on for linguists and engineers. The session's target is beginners mainly. It will cover:

  • Brief introduction to syntactic parsing and  probabilistic Context free grammar (PCFG).

The talk will illustrate what is syntactic parsing and its challenges in Arabic, and it will give a brief introduction to PCFG.

  • Inducing grammar from The Arabic Penn Tree Bank (PATB)

This part will show a hands-on induction of the Arabic syntactic grammar from the gold standard annotated PATB.

  • Implementing a Viterbi parser using  the induced grammar and testing the accuracy of the grammar.

           This part will show audience how to use the induced grammar with a parser and test the efficiency of the induced grammar.

It is recommended that you take your own laptop with you and be prepared to do the experiments yourself.
