addressing these challenges and leveraging technological innovations, financial institutions can unlock the full
potential of reference data, driving greater efficiency, transparency, and competitiveness in the global marketplace.
Literature Review:
Reference data plays a crucial role in financial data analysis, presenting both challenges and opportunities. The use of
general knowledge sources such as Wikipedia and news articles in creating datasets for relation extraction (RE)
hinders progress and adoption within the financial world [1]. The choice of reference rate in the computation of
financial sector output, specifically FISIM, has been a topic of debate among national accountants [2].
Multidimensional reference models and analysis graphs can benefit small and medium-sized enterprises (SMEs) and
multinational companies in data analysis, providing lower obstacles for SMEs and increased compliance for
multinational companies [3]. The surge in digital data generated by financial organizations has led to the development
of big data and AI systems in digital finance, but there is a lack of standardized approaches for their development and
deployment [4]. Intelligent algorithms and technologies such as natural language processing (NLP) and knowledge
graphs (KG) can be used to process and understand the wide variety of financial data, enabling the identification of
risks and opportunities [5].

Background:
The concept of big data has gained significant attention in recent years, heralded as the next frontier for productivity,
innovation, and competition. With the proliferation of internet usage, the volume of data generated has surged
exponentially. For instance, by 2018, the number of internet users had grown to over 3.7 billion people, marking a
7.5% increase from 2016. This exponential growth is further exemplified by the staggering increase in data generation
worldwide, from over 1 zettabyte (ZB) in 2010 to 7 ZB by 2014.
In its nascent stages, big data was characterized by three main attributes, often referred to as the three V's: Volume,
Velocity, and Variety. Volume denotes the massive amount of data generated every second, encompassing the size
and scale of datasets. While defining a universal threshold for what constitutes 'big data' is challenging due to the
temporal and contextual nature of data, datasets residing in the exabyte (EB) or ZB ranges are generally considered
as such. For example, retail giant Walmart collects a staggering 2.5 petabytes (PB) of data from over a million
customers every hour. However, challenges persist even for datasets of smaller sizes, as traditional data analysis
techniques may struggle to handle the scalability and uncertainty introduced by such volumes.
Variety pertains to the diverse forms of data present within a dataset, including structured, semi-structured, and
unstructured data. Structured data, typically stored in relational databases, is well-organized and easily sorted.
Conversely, unstructured data, such as text and multimedia content, lacks a predefined organization, posing challenges
for analysis. Semi-structured data, found in NoSQL databases, contains tags to delineate data elements, yet
72 Harish Padmanaban
maintaining this structure often falls to the user. The conversion between different data types, representation of mixed
data types, and changes to the underlying structure of the dataset at runtime can introduce uncertainty, further
complicating data analysis processes.
While the three V's provided a foundational framework for understanding big data, subsequent refinements expanded
upon this model. In 2011, IDC introduced a fourth V: Value, emphasizing the importance of deriving actionable
insights from data. Furthermore, in 2012, Veracity was identified as a fifth characteristic, highlighting the significance
of data accuracy and reliability in decision-making processes.
In light of these characteristics, analyzing big data poses unique challenges and opportunities, necessitating advanced
analytics processes to address the inherent uncertainty and complexity of such datasets.

Analytics algorithms encounter challenges when handling multi-modal, incomplete, and noisy data. Traditional
techniques, like data mining algorithms, are typically designed to process well-formatted input data, which may not
effectively handle incomplete or differently formatted data. This paper focuses on the uncertainty inherent in big data
analytics, which can impact the dataset itself.
Efficiently analyzing unstructured and semi-structured data presents challenges due to their diverse sources and varied
representations. Real-world databases often contain inconsistent, incomplete, and noisy data, necessitating
preprocessing techniques such as data cleaning, integration, and transformation to remove noise. Data cleaning
techniques address issues of data quality and uncertainty, such as noise and inconsistent data, leading to enhanced
performance in data analysis, for instance, improving classification accuracy in machine learning.
Velocity, emphasizing the speed of data processing, is critical, particularly in scenarios where data must be processed
in real-time or near-real-time. For example, Internet of Things (IoT) devices continuously generate large amounts of
sensor data, where delays in processing could have severe consequences, like patient injury or death in medical
monitoring systems. Similarly, data processing in cyber-physical systems relies on strict timing standards, leading to
challenges when big data application data isn't delivered on time.
Veracity, representing data quality, is paramount in big data analytics. Poor data quality can lead to significant
economic losses. Inconsistent, noisy, or incomplete data can undermine accuracy and trust in analytics results. For
example, social media data may contain mixed personal and official information, complicating analysis. In healthcare,
ambiguous or inconsistent data can hinder disease trend detection, impacting public health responses.
Value, contextualizing data for decision-making, underscores the significance of deriving actionable insights from big
data. Companies like Facebook, Google, and Amazon leverage big data analytics to enhance products and services,
demonstrating the value of insightful data analysis in business decisions.
Uncertainty pervades every phase of big data analytics and arises from various sources, including data collection
variance, concept variance, and multimodality. Missing attribute values, biased training data, and incomplete sampling
can lead to inaccurate results. Augmenting analytics techniques to handle uncertainty is crucial, with techniques such
as Bayesian theory, belief function theory, probability theory, classification entropy, fuzzy logic, Shannon's entropy,
and rough set theory being common approaches. Evaluating uncertainty levels is vital for accurate analytics results,
with models like probability theory and fuzzy set theory enhancing the accuracy and meaning of analysis outcomes.
Big data analytics
Big data analytics refers to the process of analyzing extensive datasets to uncover patterns, correlations, market trends,
user preferences, and other valuable insights that were previously inaccessible with traditional tools. With the
establishment of big data's five characteristic "V's" (Volume, Variety, Velocity, Veracity, and Value), analysis
techniques have needed reevaluation to overcome limitations in processing time and space. In the contemporary digital
74 Harish Padmanaban
era, opportunities for leveraging big data are burgeoning. The global market for big data technologies and services is
projected to experience a robust annual growth rate of approximately 36% between 2014 and 2019, with the global
revenue for big data and business analytics anticipated to soar by over 60%.
Advanced data analysis techniques such as Machine Learning (ML), data mining, Natural Language Processing
(NLP), and Computational Intelligence (CI), coupled with potential strategies including parallelization, divide-andconquer, incremental learning, sampling, granular computing, feature selection, and instance selection, play pivotal
roles in converting big problems into manageable ones. These techniques and strategies enable better decision-making,
cost reduction, and more efficient processing.
Parallelization, for instance, reduces computation time by breaking down large problems into smaller tasks and
executing them simultaneously across multiple threads, cores, or processors. The divide-and-conquer strategy involves
subdividing a complex problem into smaller, more manageable subproblems, solving each independently, and then
integrating the solutions to address the overarching issue.
Incremental learning, particularly useful for streaming data, updates learning algorithms over time with new data
inputs rather than relying solely on existing data. Sampling serves as a data reduction method, allowing for the analysis
of patterns within large datasets by examining a subset of the data. Granular computing simplifies large datasets by
grouping elements into subsets or granules, effectively managing uncertainty within the search space.
Feature selection, a conventional approach in data mining, involves choosing a subset of relevant features to provide
a more concise and precise representation of data. Instance selection, a crucial component of data preprocessing,
reduces training sets and runtime during classification or training phases.
Given the costs and computational challenges associated with uncertainty, addressing uncertainties in big data
analytics is critical for developing robust and high-performing systems. In the subsequent section, we explore several
open issues regarding the impacts of uncertainty on big data analytics.
Uncertainty in Big Data Analytics: A Perspective
This section delves into the impact of uncertainty on three key Artificial Intelligence (AI) techniques employed in big
data analytics: Machine Learning (ML), Natural Language Processing (NLP), and Computational Intelligence (CI).
While numerous other analytics techniques exist, our focus remains on these three, exploring their inherent
uncertainties and discussing strategies for mitigation.
Machine Learning in the Context of Big Data:
Machine Learning (ML) plays a central role in data analytics, enabling the creation of predictive models and
facilitating knowledge discovery to drive data-driven decision-making. However, traditional ML methods often
struggle to efficiently handle the unique characteristics of big data, such as its large volumes, high speeds, varied

75
types, low value density, and inherent uncertainty stemming from factors like biased training data or unexpected data
types.
To address these challenges, advanced ML techniques have been proposed, including feature learning, deep learning,
transfer learning, distributed learning, and active learning. Feature learning enables systems to automatically detect or
classify features from raw data, crucially impacting ML algorithm performance. Deep learning algorithms excel at
analyzing vast datasets and extracting valuable insights from diverse data sources, albeit at a high computational cost.
Distributed learning mitigates scalability issues by distributing calculations across multiple workstations, thus scaling
up the learning process. Transfer learning enhances learning in new contexts by transferring knowledge from related
domains. Active learning accelerates ML activities by adaptively collecting the most useful data, effectively
overcoming labeling problems.
The uncertainties inherent in ML techniques primarily stem from learning from data with low veracity or incomplete
data and data with low value unrelated to the current problem. Active learning, deep learning, and fuzzy logic theory
stand out as effective strategies for reducing uncertainty in ML. Active learning addresses labeling challenges by
selecting crucial instances for labeling, circumventing the need for manual labeling of large datasets. Deep learning
tackles incompleteness and inconsistency issues in classification procedures, while fuzzy logic theory efficiently
models uncertainty, exemplified by techniques like fuzzy support vector machines (FSVMs), which apply fuzzy
membership to input points in support vector machines (SVM).
In summary, uncertainty presents significant challenges for ML techniques in big data analytics, impacting training
sample completeness, classification boundary clarity, and target data knowledge. Strategies like active learning, deep
learning, and fuzzy logic theory offer promising avenues for mitigating these uncertainties, paving the way for more
robust and accurate analytics outcomes.
Discussion:
This paper has examined the profound impact of uncertainty on big data analytics, encompassing both the analytics
techniques employed and the datasets themselves. Our objective was to provide insights into the current state-of-theart in big data analytics techniques, elucidate how uncertainty can hinder these techniques, and identify lingering open
issues in the field. Through our exploration of common techniques, we aim to equip fellow researchers and
practitioners with valuable insights to inform their own endeavors.
While our discussion has primarily focused on the five V's of big data—volume, variety, velocity, veracity, and
value—it's important to note that numerous other V's exist, suggesting potential avenues for further investigation.
Despite substantial research attention being devoted to volume, variety, velocity, and veracity, relatively less emphasis
has been placed on value, particularly concerning data pertinent to corporate interests and decision-making within
specific domains.
Future Research Directions:
76 Harish Padmanaban
Our exploration has unveiled several promising avenues for future research in this domain. Firstly, there is a pressing
need for further investigation into the interplay between various characteristics of big data, as they do not exist in
isolation but rather interact dynamically in real-world scenarios. Secondly, it is imperative to empirically assess the
scalability and efficacy of existing analytics techniques when applied to big data contexts.
Thirdly, the development of new techniques and algorithms, particularly in the realms of Machine Learning (ML) and
Natural Language Processing (NLP), is essential to meet the real-time demands of decision-making based on vast
datasets. Fourthly, there is a crucial need for more comprehensive exploration of methods to effectively model
uncertainty in ML and NLP, as well as strategies to represent uncertainty arising from big data analytics processes.
Lastly, while Computational Intelligence (CI) algorithms have shown promise in addressing ML challenges and
uncertainty in data analytics, there remains a dearth of CI metaheuristic algorithms tailored specifically for big data
analytics to mitigate uncertainty. Future research efforts should thus focus on the development and refinement of such
algorithms to enhance the robustness and efficiency of big data analytics in the face of uncertainty.
