Data collection is the initial and fundamental step in any Data Science or Analytics project, and on which all following activities rely, from data analysis to model deployment.
With the pervasive presence of APIs and Cloud Computing, I am ever more intrigued in maximizing the efficiency and level of automation of data collection activities for both work and personal projects.
In the latter category, I have been interested in collecting data from online home-rental platforms in the UK market (Zoopla, RightMove, OnTheMarket, and similar) with the aim of extracting image and text data to be processed for use in machine learning models (for use cases such as prediction of a property’s price, extraction of key features from image-data to infer a listing’s true value, processing of customer reviews through NLP techniques, etc…)
In the following lines, I aim to discuss how to potentially go about:
I gave the article a broader cut, which touches upon market and regulatory considerations to be made when reasoning around data collection for potentially commercial purposes, as well as the more technical considerations of working with APIs, as I realize there are multiple layers to be surfaced within this very interesting topic.
I hope the below key points will result useful in setting up the Data Collection block of your current and future Data Science projects, no matter your industry focus.
In two-sided markets such as online home rental platforms, which are dominated by supply and demand agents (on the supply side, homeowners looking to rent, either directly or through a real-estate agent; on the demand side, individuals looking to rent), you are going to find the most data, both in terms of quantity and quality, on those platforms which drive the majority of traffic in a given market, from both supply and demand sides.
In this sense, you need to identify the platforms which hold the majority of market power as they pull and attract most eyeballs. Knowing the market’s distribution of overall traffic/data volume is very useful if you are looking to pull high amounts of data over time, and do not want to be integrating multiple data streams coming from smaller market players.
In the UK’s online home rental market, the majority of the traffic and listings is distributed between the top 1–5 players, and those companies (the left of the curve in the below illustrative distribution) are therefore the ones on which you want to focus your data collection efforts on.

This is of course a double-edged sword, as the big players from which you are going to be sourcing from have high leverage when it comes to entering data-sharing agreements, which allows them to:
1) act as de-facto gatekeepers to a particular market and set their own data usage policies, especially in a less regulated market scenario
2) charge more per the same unit of data volume when entering data sharing agreements
3) effectively monitor potential competitive threats to their core-business from startups who require access to their data and who are thus more dependent on their services

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.
If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.
In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.

The buzz around data science has sent many youngsters and professionals on an upskill/reskilling spree. Prof. Raghunathan Rengasamy, the acting head of Robert Bosch Centre for Data Science and AI, IIT Madras, believes data science knowledge will soon become a necessity.
IIT Madras has been one of India’s prestigious universities offering numerous courses in data science, machine learning, and artificial intelligence in partnership with many edtech startups. For this week’s data science career interview, Analytics India Magazine spoke to Prof. Rengasamy to understand his views on the data science education market.
With more than 15 years of experience, Prof. Rengasamy is currently heading RBCDSAI-IIT Madras and teaching at the department of chemical engineering. He has co-authored a series of review articles on condition monitoring and fault detection and diagnosis. He has also been the recipient of the Young Engineer Award for the year 2000 by the Indian National Academy of Engineering (INAE) for outstanding engineers under the age of 32.
Of late, Rengaswamy has been working on engineering applications of artificial intelligence and computational microfluidics. His research work has also led to the formation of a startup, SysEng LLC, in the US, funded through an NSF STTR grant.

Data Science becomes an important part of today industry. It use for transforming business data into assets that help organizations improve revenue, seize business opportunities, improve customer experience, reduce costs, and more. Data science became the trending course to learn in the industries these days.
Its popularity has grown over the years, and companies have started implementing data science techniques to grow their business and increase customer satisfaction. In online Data science course you learn how Data Science deals with vast volumes of data using modern tools and techniques to find unseen patterns, derive meaningful information, and make business decisions.
Advantages of Data Science:- In today’s world, data is being generated at an alarming rate in all time lots of data is generated; from the users of social networking site, or from the calls that one makes, or the data which is being generated from different business.
