SENTIMENT ANALYSIS IN SOCIAL MEDIA CONTENTS USING NATURAL LANGUAGE PROCESSING TECHNIQUES

Author: Tamara Álvarez López Advisors: Enrique Costa Montenegro, Milagros Fernández Gavilanes Affiliation: AtlantTIC Research Center, University of Vigo MOTIVATION

Growth of social networks and their users.

New way of expression.

Very valuable information for companies, who need to analyse it.

Great amount

• f

information available

• nline.

Difficult to analyse.

Natural Language Processing (NLP) techniques.

Applied in fields like: Sentiment Analysis (SA), Aspect Extraction, Text Generation, Entity Recognition, etc.

OBJECTIVES

Automatic sentence-level SA system.

Fine-grained SA system, by means of aspect detection.

Application and adaptation to different datasets and contexts.

Implementation for English and Spanish. e.g. Service was nice but price was not worth it and food quality was very miserable. Service Price Food quality Sentence-level SA Aspect-level SA

Results and Discussions Radio Frequency Propagation, Characterization And Measurements For Antenna Sensor Networks With Applications In Smart Farming

Hicham Klaina, supervised by Ana Vazquez Alejos and Otman Aghzout

Using this WSN topology, farmer is allowed to monitor his farm in real time using his smartphone

• r laptop whenever and wherever he is.

WSN for farm monitoring using Raspberry: Traceability of food transportation using Arduino: Data model offered to farmers to trace their food transportation which is a part of the new V2X technology, from the farm to the table. Food traceability in real-time

• n

Google Maps will accessible to the farmer. Measurements show that a significant change in path loss occurs when lowering the height of the antennas near to ground after a break distance, changing the propagation channel model. Measurements demonstrate that RFID tags type, positioning and food dielectric constant have a big influence

• n tags attached to food detection
• performance. Novel design needed.

DATA-DRIVEN ALLOCATION OF NETWORK RESOURCES IN UDNs

SILVESTRE LOMBA MALTA, SUPERVISED BY MANUEL FERNANDEZ VEIGA

• Ultra-dense networks (UDN) have been considered one of the most advanced technologies in 5G and

can be the key to meet users’ expectations.

• Due to UDN characteristics, energy management and energy consumptions are serious challenges to

network operators.

• Studies have concluded that Base Stations consume about 60%-80% of energy use in cellular networks.
• In my thesis, I would like to contribute with:
• New techniques for sampling, compressing and summarizing network mobility information in real-

time.

• Evaluate the performance improvements of knowing mobility and traffic patterns in UDNs, as far as

energy-efficiency is concerned.

• Develop deterministic mean-field approximations for predicting the performance in large UDNs.
