Data Wrangling | Automated Web Scraping | OCR | Data Visualization
We have solved data management needs of various clients across the globe. We have provided political parties, research organizations and small enterprises with:
Many organizations like hospitals and govt agencies publish data in the form of PDF. We extract this data and transform it into structured usable form.
Large volumes of data are being published to website these days. Not all these sites have APIs. In such cases we employ automated web scraping programs to acquire the data.
Data spread across large number of excel spreadsheets is not of much use. We tame such data, harness and it make it ready to be published on a Web interface.
OCR is the technique of extracting text from images. Often PDF files have data embeded as an image. In such cases we employ OCR to extract and parse the data.
Data extracted from PDFs, images and web scraping is often not in a usable form. It has to undergo "cleaning". This process is called data wrangling or munging.
Once the data is ready in a structured and clean form, its best to visualize such data to draw better insights. Bokeh is an excellent tool for data visualization.
Python has excellent libraries and tools required for large scale data extraction, wrangling and analysis
Pandas is a software library written for the Python programming language for data manipulation and analysis
Bokeh is a Python library for interactive data visualization that targets web browsers for representation
Apache Spark is an open-source distributed general-purpose cluster-computing framework. Spark provides an interface for programming entire clusters with implicit data parallelism and fault tolerance
GCP offers fast virtual machines running Ubuntu Linux. Google Cloud Vision API provides excellent OCR (Optical Character Recognition) required to extract text from image based PDFs
Ubuntu Linux is the best operating system to run Python, Pandas and Spark. The native BASH scripting language provides many necessary text manipulation tools like awk, grep and sed.
"We had a large number of excel sheets carrying humongous data related to travel industry. Comquest did a great job in organizing that data, analyzing it and made it available in a simple and usable form on our website. "
"They did an excellent job in extracting tabular data from physical books, parsing it and making it usable in the form of spreadsheets."
"Comquest played an integral role in the successful roll-out of our "Missing Voters Identification" project.
Working with huge data files in limited time was very difficult task, Naveed Ahmed and his team has done great work in processing them, I look forward to seeing him continue achieving greatness. Thank you for all of your efforts."
