Junior Natural Language Processing Specialist - Virtual Intern

Objective: Develop a comprehensive planning document for an NLP project that outlines your approach, pipeline design, task objectives, and risk management strategies. You will create a plan that will serve as the blueprint for future stages in the virtual internship.

Expected Deliverables: A DOC file that includes a project overview, detailed project planning document, pipeline diagrams, identified challenges, proposed solutions, and a timeline for execution.

Key Steps:

1. Research: Investigate publicly available literature and online resources about NLP project life cycles and best practices for planning. Understand various NLP tasks such as text classification, sentiment analysis, and named entity recognition.
2. Define the Project: Choose a specific NLP problem to address. Clearly define the problem statement, target audience, and expected outcomes.
3. Pipeline Design: Outline a detailed pipeline that includes data collection, preprocessing, model selection, training, evaluation, and iteration. Use diagrams to illustrate the workflow.
4. Risk Analysis: Identify potential challenges and risks and propose mitigation strategies.
5. Timeline & Milestones: Develop a realistic timeline with milestones and deliverables for the project.

Evaluation Criteria: Your submission will be evaluated based on clarity of the project plan, depth of research, feasibility of the proposed pipeline, thoroughness of risk analysis, and quality of presentation in the DOC file.

This task is designed to be completed in approximately 30-35 hours and will provide a strong foundation for subsequent tasks in your internship. Ensure that every section is well-documented, and your plan is both detailed and logically organized.

Objective: Develop a detailed strategy document focusing on the collection, cleaning, and annotation of textual data for an NLP task. Your task is to create a document that outlines a complete data pipeline starting from data sourcing through to preprocessing and annotation.

Expected Deliverables: A DOC file that includes a data sourcing strategy, cleaning protocol, annotation guidelines, and a discussion of potential challenges. Provide step-by-step procedures and justify your choices using publicly available resources.

Key Steps:

1. Data Sourcing: Identify publicly available datasets or sources where textual data can be acquired. Describe the criteria for selecting these sources and discuss any ethical or legal considerations.
2. Data Cleaning: Develop a protocol for cleaning the collected data. Include steps such as removal of noise, normalization of text (tokenization, stemming, lemmatization), and handling of missing values.
3. Annotation Guidelines: Create a set of guidelines for annotating the data in the context of your chosen NLP task. Explain the rationale behind the annotation scheme and discuss inter-annotator reliability.
4. Documentation: Provide a detailed explanation of each step and explain how you will ensure data quality.
5. Validation: Outline a method to validate the effectiveness of your cleaning and annotation process.

Evaluation Criteria: The submission will be assessed on clarity, thoroughness of the data strategy, justification of methodological choices, and quality of documentation in the DOC file. The document should be sufficiently detailed, exceeding 200 words, and should serve as a clear guide for executing the data pipeline.

Objective: Implement a baseline NLP model for a common text classification task using publicly available libraries and tools. Create a detailed report documenting your approach, code snippets, and analysis of the initial results.

Expected Deliverables: A DOC file that includes a description of the selected model, implementation details, code examples (presented as text snippets), and preliminary performance metrics along with interpretation.

Key Steps:

1. Model Selection: Research and choose a simple, interpretable model (such as Naive Bayes, Logistic Regression, or a shallow neural network) suitable for text classification.
2. Implementation: Develop a baseline model using public libraries (e.g., NLTK, scikit-learn, or spaCy). Document the implementation process clearly, providing pseudo-code and code snippets where applicable.
3. Experimentation: Run initial experiments using a publicly available dataset (if applicable) or simulate experiments based on theoretical scenarios. Report key performance metrics such as accuracy, precision, recall, and F1 score.
4. Analysis: Include a critical analysis of the model’s performance, discussing any observed limitations or challenges.
5. Future Directions: Propose potential improvements to the baseline model.

Evaluation Criteria: Your document will be evaluated based on the clarity of the model explanation, accuracy of the experimental framework, depth of performance analysis, and overall presentation in the DOC file. The report must be detailed and self-contained, demonstrating your understanding of baseline model implementation in NLP.

Objective: Conduct a comprehensive evaluation of your baseline NLP model with a focus on error analysis. Prepare a detailed DOC file that explains your evaluation process, presents the performance results, and identifies areas for improvement.

Expected Deliverables: A DOC file that includes an evaluation report with performance metrics, confusion matrices, error analysis summaries, and recommendations for model improvements.

Key Steps:

1. Metric Identification: Identify and describe the key metrics (such as accuracy, F1 score, precision, and recall) that are most suitable for evaluating your NLP model.
2. Performance Evaluation: Describe how you will calculate these metrics and present the results in a clear format. Consider using tables or charts (described in text for the DOC file) to summarize your findings.
3. Error Analysis: Perform an in-depth error analysis by identifying patterns in misclassifications or any systematic biases. Detail specific examples and discuss potential causes for these errors.
4. Diagnostic Report: Propose diagnostic techniques or experiments to validate your findings concerning the errors.
5. Improvement Strategies: Based on your error analysis, recommend feasible strategies to improve model performance going forward.

Evaluation Criteria: The DOC submission will be evaluated on the completeness and clarity of the performance evaluation, depth of error analysis, quality of recommendations for model improvement, and overall thoroughness in documenting the process. Ensure that the report exceeds 200 words and is self-contained, presenting a logical flow from evaluation to improvement proposals.

Objective: Prepare a comprehensive project report that summarizes your work over the past four weeks and outlines future improvement proposals for the NLP model and overall project pipeline. This should include a reflective evaluation of your process and strategies for further model enhancement.

Expected Deliverables: A DOC file containing a complete project summary, future improvement proposals, detailed reflections on what went well and what could be improved, and an integrated plan for the next steps in an NLP project.

Key Steps:

1. Project Recap: Summarize the key findings, workflows, and outcomes from the previous tasks. Include highlights from the planning, data processing, model implementation, and evaluation phases.
2. Strengths & Weaknesses Analysis: Evaluate the strengths and weaknesses of the current approach, supported by quantitative and qualitative evidence from your previous submissions.
3. Future Improvement Ideas: Propose detailed strategies aimed at addressing the weaknesses identified in your evaluation. Discuss potential adjustments in model architecture, data processing techniques, and additional evaluation metrics that could be integrated in the future.
4. Integration Plan: Develop a roadmap that integrates these proposed changes and prioritizes initiatives based on impact and feasibility.
5. Reflection: Reflect on your learnings during this internship period and articulate any insights or challenges you encountered. Include a discussion of how this exercise has prepared you for a career in NLP.

Evaluation Criteria: Your final report will be judged on the clarity and thoroughness of the project summary, the thoughtfulness of your improvement proposals, and the logical coherence of your integration plan. The report must exceed 200 words, be self-contained, and serve as a conclusive document that encapsulates your learning journey and strategic vision for future developments in NLP.
