==== Open PhD position at QWANT search engine and INRIA on Artificial
Intelligence: Argument Mining and Emotions ====
--- About Inria ---
Inria, the French National Institute for computer science and applied
mathematics, promotes "scientific excellence for technology transfer and
society". Graduates from the world’s top universities, Inria's 2,700 employees
rise to the challenges of digital sciences. With its open, agile model, Inria
is able to explore original approaches with its partners in industry and
academia and provide an efficient response to the multidisciplinary and
application challenges of the digital transformation. Inria is the source of
many innovations that add value and create jobs.
--- Context ---
The ANSWER project is leaded by the QWANT search engine and the INRIA Sophia
Antipolis Méditerranée research center. This proposal is the winner of the
"Grand Challenges du Numérique" (BPI) and aims to develop the new version of
the search engine www.qwant.com with radical innovations in terms of search
criteria, indexed content and privacy of users. The scientific and
technological challenges addressed by the project consider several evolutions
of the Web to adapt to them on the one hand (heterogeneity of data) and to
anticipate them on the other hand (personalization and respect for privacy,
increase in granularity and number of criteria for qualification of Web
content). This job description describes one of the open positions within this
project.
--- Assignment ---
This position will be attached to Inria.
The field of emotion analysis and sentiment analysis is not new, and it is
often oriented towards the analysis of the emotions of the users and the
determination of the polarity of a text, i.e., the text is positive or
negative. In the ANSWER project, we aim to tackle the opposite challenge,
namely we aim to answer the following research question: how to indicate to
the user which are the emotions characterizing the results of her search in
order to make it a criterion of choice? We focus on powerful algorithms to
define new criterions for filtering search results, i.e., the expression of a
feeling in the answers found by the search engine. The final goal is to
extract effective and scalable indicators of sentiment, emotions, and
argumentative relations in order to offer the users additional means to filter
the results selected by the search engine.
--- Main activities ---
Wa aim to address the above mentioned issue with an innovative approach, so
that the textual elements to which we wish to associate a polarity will no
longer be considered in their individuality but connected to each other by
polarized relations to be analysed in a higher level setting. The three main
tasks of this PhD thesis will be:
1) Automatic detection of emotions and sentiment in the text (i.e., the
association of a positive/negative polarity to a paragraph based on the
polarity of the terms present in the text).
2) From the annotated data in step (1), prediction of the polarity of
relations between the text spans with the combination of argument mining
methods for relation prediction and emotion detection techniques.
3) Active Learning approach to improve sentiment analysis algorithms, based on
predicted relations predicted in step (2).
