Title: Generating Definitions and Semantic Properties of Words with Deep 
Learning and Rich Lexical Resources

Domain: computer science
Speciality: natural language processing

Summary:
The PhD thesis will consist in investigating new methods to extract appropriate 
semantic knowledge for a lexical unit in a given context. In particular, given 
a word and a context, the proposed methods will aim at automatically generating 
its definition as well as its semantic properties (e.g. coarse-grained sense, 
synonyms), adapted not only to its occurrence context, but also to the user.

With the deep learning revolution, the PhD project hypothesis is that it is now 
possible to fully model the task with neural networks including both the 
analysis of the word and its context, and the actual generation of a defining 
sentence in natural language. Such models would be trained from the content of 
lexical resources, and enriched with language models and word representations 
learned from large textual corpora in order to capture the lexical diversity 
and language style of a general audience. This approach could be very related 
to novel neural approaches used for machine translation or automatic 
summarization that both include an analysis and a generation phase.

While the topic proposed for investigation in this PhD project is related to 
the traditional tasks of Word Sense Disambiguation and Word Sense Induction, it 
is in fact more challenging as it takes a step further: a successful system is 
expected to generate definitions even for words and word senses that are not 
covered in existing lexical resources, generalizing from existing knowledge 
bases.
