Client Overview
Our client, a leading global media monitoring firm, specializes in analyzing political speeches, corporate announcements, and public addresses to provide actionable insights to their clients. With a vast repository of speech transcripts, they faced challenges in efficiently extracting meaningful information to inform strategic decisions.
Challenges
The client grappled with several issues:
- Manual Analysis: The existing process was labor intensive, requiring analysts to manually sift through transcripts to identify key themes, sentiments, and entities.
- Inconsistency: Human analysis led to subjective interpretations, resulting in inconsistent insights.
- Scalability: With an ever growing volume of speeches, scaling the analysis without compromising quality was a significant hurdle.
Objectives
The client aimed to:
- Automate Analysis: Reduce manual effort by automating the extraction of key themes, sentiments, and named entities.
- Enhance Consistency: Ensure uniformity in analysis across different speeches and analysts.
- Improve Efficiency: Accelerate the turnaround time for delivering insights to clients.
Our Approach
We developed a comprehensive speech analysis tool leveraging advanced Natural Language Processing (NLP) techniques. Our solution encompassed:
1. Data Preprocessing
- Cleaning Transcripts: Removed timestamps, filler words, and irrelevant content to ensure clarity.
- Normalization: Standardized text for consistent analysis.
2. Topic Modeling
- Latent Dirichlet Allocation (LDA): Implemented LDA to identify underlying themes within speeches, allowing users to grasp the core message quickly.
3. Sentiment Analysis
- Sentence Level Analysis: Assessed the sentiment of each sentence to determine the overall tone of the speech.
4. Named Entity Recognition (NER)
- Entity Extraction: Identified and highlighted mentions of key figures, organizations, and locations to provide context.
5. Interactive Visualizations
- Word Clouds: Displayed prominent terms to visualize the focus areas of speeches.
- Charts and Graphs: Presented sentiment distributions and entity mentions for intuitive understanding.
6. User Friendly Interface
- Streamlit Application: Developed an interactive web application enabling users to upload datasets, select specific speeches, and view analyses seamlessly.
Results
Post implementation, the client experienced significant improvements:
- Efficiency: Reduced analysis time by 70%, enabling faster delivery of insights.
- Consistency: Achieved uniform analysis across different speeches, enhancing reliability.
- Scalability: Handled large volumes of data effortlessly, accommodating the growing repository of speeches.
- User Engagement: The intuitive interface led to increased adoption among analysts, fostering a data driven culture.
Client Feedback
