The Power of Unstructured Data Processing

In the digital age, data is the new oil. It fuels the engines of business, powering decision-making, strategy formulation, and operational efficiency. However, not all data is created equal. While structured data neatly fits into databases and spreadsheets, unstructured data, which constitutes a staggering 80-90% of all data, poses a unique challenge and opportunity. This article delves into the world of unstructured data, its processing, and the immense value it holds for businesses.

Understanding Unstructured Data

Every time we use an electronic device, we generate data. This data can be classified into structured and unstructured data. Structured data is qualitative, organized in a specific database format, and includes categories such as names, credit card numbers, or telephone numbers. On the other hand, unstructured data, despite having an internal structure, is not predefined by data models. It is stored in its native format until needed for use.

Unstructured data is diverse and includes social media data, surveillance data, geospatial data, audio data, meteorological data, and reports, invoices, records, emails, and productivity applications. The value of unstructured data lies not in its volume but in what it reflects: trends, attitudes, conflicts. The ability to analyze this data and turn the conclusions into strategic decisions is a matter of significant importance.

Processing Unstructured Data

The sheer volume of unstructured data necessitates automated data collection and digestion techniques to convert them into forms that can be efficiently subjected to automated processes. This processing is primarily based on two techniques:

  1. Optical Character Recognition (OCR): OCR is the text digitization process. It automatically identifies the data based on an image, symbols, or characters that belong to an alphabet, and then stores them as data.
  2. Natural Language Processing (NLP): NLP is an area of Artificial Intelligence (AI) that analyzes written and spoken content, understands its meaning, and predicts what is likely to follow it. It simulates the ability of the human brain to process natural languages such as English, Spanish, Chinese, etc. NLP can infer the meaning of text data in a context even when documents do not follow a standard template.

Analyzing Unstructured Data

Unstructured data analysis involves several steps, including identifying relevant data sources, eliminating unnecessary data or noise, and identifying suitable technology tools for data collection, cleansing, storage, processing, analysis, and presentation. Data lakes are often used to store unstructured data in the native format along with associated metadata.

Once these steps are in place, you can plan your data processing and analysis methodology. Some of the best ways to analyze unstructured data include:

  1. Metadata Analysis: Metadata provides information about data and plays an important role in the management, storage, and analysis of unstructured data. It helps to facilitate subsequent search and analysis.
  2. Natural Language Processing (NLP): NLP is a machine learning methodology that helps to analyze the meaning of unstructured text data. It uses models like ‘Bag of words’, Tokenization, Stop words removal, Stemming, Lemmatization, and Topic modeling to process unstructured text.
  3. Image Analysis: AI-based image analysis can retrieve images based on unstructured data, such as MRI images that match a certain brain volume, or X-rays of the spine based on the match with a given spine image. Optical character recognition (OCR) technologies convert the text in image files into text data that can be read and processed.
  4. Data Visualization: Data visualization is the graphical representation of data in a way that promotes easier understanding. Visualization techniques can be used to highlight entities, reveal topics or keywords, identify concepts, and present sentiment analysis.

Latent Dirichlet Allocation (LDA) and Unstructured Data

Latent Dirichlet Allocation (LDA) is a popular topic modeling technique that is often used in the analysis of unstructured text data. LDA is a generative probabilistic model that allows sets of observations to be explained by unobserved groups. In the context of text data, these unobserved groups or topics help explain why some parts of the data are similar.

For example, if observations are words collected into documents, LDA would posit that each document is a mixture of a small number of topics. The words in each document are indicative of its topics. LDA is particularly useful for finding the main themes in large text corpora, summarizing the texts, and for further text analysis.

The Value of Unstructured Data

The value of unstructured data depends on how it is processed. An AI-powered unstructured data platform that automatically classifies a wide range of document types, analyzes, and extracts the most important information quickly and with a high level of accuracy is key. From that point on, the automation of repetitive manual processes enhances performance, reduces human errors, and enables employees to concentrate on tasks that add value.

Unstructured data analysis can benefit any sector. In healthcare, it can optimize and improve the quality of care, and innovation and analysis in clinical processes. In insurance, it can improve and identify problems in a short space of time. In banking, it can help analyze a person’s employment record or look for information in a public deed. In basic services, it can identify customers’ and users’ aspirations, needs, and desires to develop new services or improve existing ones.

The Challenges of Unstructured Data Processing

While unstructured data holds immense potential, it also presents unique challenges. The sheer volume and diversity of unstructured data make it difficult to manage and analyze. Traditional data management tools and techniques are often ill-equipped to handle unstructured data, necessitating the use of advanced technologies such as AI and machine learning.

Moreover, unstructured data often lacks the metadata that makes structured data easy to search and analyze. This makes it difficult to find relevant data and understand its context. Furthermore, unstructured data can come from a variety of sources, each with its own formats and standards, adding to the complexity of data management.

Finally, unstructured data often contains sensitive information, such as personal data, which raises privacy and security concerns. Businesses need to ensure that they handle unstructured data in a way that complies with data protection regulations and respects individual privacy.
