NLP Expert Needed for Multimodal Financial Sentiment Analysis Project
Budget: €750 – €1,500 EUR
Description:
We are seeking a skilled Natural Language Processing (NLP) expert to lead the development and execution of key analytical components for a project focused on financial sentiment analysis related to IPO performance. The role involves handling the complete data lifecycle, including collection, preprocessing, sentiment analysis, and predictive modeling.
Key Responsibilities:
1.Multimodal Data Collection:
-Gather textual data from social media, online searches, and financial documents using web scraping techniques and APIs. Data sources include platforms like Twitter, Google Trends, and official IPO documents.
2.Data Preprocessing and Integration:
-Clean, normalize, and preprocess the collected data. Apply advanced techniques such as tokenization and stemming to textual data. Extract features from visual data and integrate them into a comprehensive dataset.
3.Sentiment Analysis:
-Implement state-of-the-art NLP models like BERT for sentiment analysis. Utilize deep learning models such as convolutional neural networks (CNNs) and LSTMs for processing multimodal data.
4.Statistical Analysis:
-Perform a series of statistical tests including Granger causality, stationarity tests, and autocorrelation analysis to identify and validate relationships within the data.
5.Predictive Modeling and Validation:
-Develop and fine-tune predictive models using ensemble learning techniques. Initially, the models will be tested on historical IPO data to assess how past sentiment contributed to IPO performances. After achieving a robust model, it will be applied to predict the outcomes of future incoming IPOs, providing valuable insights for potential market behavior.
Requirements:
-Strong experience in NLP and sentiment analysis, particularly within financial contexts.
-Proficiency with tools like Python, PyTorch, and data manipulation libraries such as pandas.
-Experience with deep learning models (BERT, CNNs, LSTM) and statistical analysis techniques.
-Hands-on experience in data collection via web scraping and API integration.
-Strong analytical skills with a focus on integrating and processing large datasets.
Preferred Qualifications:
-Previous experience working on financial sentiment analysis, particularly related to IPOs.
-Understanding of multimodal data processing (text, visual, and vocal).
-Familiarity with predictive modeling and machine learning techniques in finance.
How to Apply:
-Please provide an overview of your experience related to the key responsibilities listed above. Include any relevant projects or case studies that demonstrate your expertise in NLP and sentiment analysis.
