4 Generating Insights from Unstructured Text Data

Natural Language Processing (NLP) techniques are fundamentaltounlockinginsightsfromtexts

4.1 Classical NLP:

Classical Natural Language Processing (NLP) refers to the classical approaches used to analyze and process human languagebeforetheriseofdeeplearningandlargelanguage models.

In the early days, NLP systems relied on manually crafted linguistic rules and symbolic methods. These systems focused on syntactic parsing, using grammar like contextfree grammar (CFG) to understand sentence structures. Early attempts at machine translation and chatbots like ELIZA were developed during this phase, with language understandinglimitedtopredefinedrulesandknowledgebasedsystems.

Withtheriseofcomputationalpowerandlargeannotated datasets, NLP moved toward probabilistic models and statistical methods. Techniques such as n-grams, Hidden Markov Models (HMMs), and Conditional Random Fields (CRFs)becamefamousfortaskslikepart-of-speechtagging, named entity recognition, and machine translation. Word embeddings like Word2Vec and algorithms like Latent Dirichlet Allocation (LDA) revolutionized word representation and topic modeling during this period. Though effective in narrow domains, classical approaches struggled with ambiguity, scalability, and generalization.

5. Integrated Analytics with both Structured and Unstructured Data

5.1 Integrating Structured and Unstructured Data

Structured data refers to information organized in a predefined manner, often in rows and columns, making it easily searchable and analyzable using traditional data processingtechniques.Examplesincludetransactionaldata, financial records, and customer information stored in relationaldatabases.

While structured and unstructured data structures are different,thegluethatconnectsthevariouskindsofdatais the standard dimensions. For example, the product identifiers are the glue between product review data and profitabilitymetrics.Similarly,patientIDisthegluebetween patient health notes and metrics. Customer ID is the glue betweenthecustomerengagementlogdataandprofitability metrics.

Withallthetechniqueslistedabove,metricsgleanedfrom theunstructureddata,suchassentimentscoresorcustomer bouncerates,willlookmorelikestructuredmetricdata. The criticalsuccessfactorforintegratingunstructureddatawith structured data is extracting insightful metrics from unstructureddata.Then,metricscreatedfromunstructured datacanbejoinedwithmetricsfromstructureddataatthe standardlevelofgranularity.Regardlessofthedatastrategy, whether stored in a data lake or warehouse, the metrics relevant for analysis and insights can be extracted and integratedintosmallerdatasetsforhumananalysis.

separate models for each type of data and merging their outputstoleveragetheuniquestrengthsofeach.Hereare some common deep-learning approaches that integrate structuredandunstructureddata:

Hybrid Networks (Parallel Networks)

Thelatefusionapproachinvolvesbuildingseparatemodels for structured and unstructured data, processing each independently,andcombiningtheiroutputslater.Structured dataishandledbytraditionalmodelslikerandomforestsor MLPs,whileunstructureddataisprocessedbydeeplearning models such as CNNs for images or RNNs for text. The outputs are concatenated and passed through a fully connected layer for the final prediction. For example, in a recommendationsystem,aCNNprocessesproductimages, anRNNhandlesproductdescriptions,andanMLPprocesses userdemographicstomakepredictions.

Early Fusion with Feature Extraction

Theearlyfusionapproachinvolvesextractingfeaturesfrom unstructured data, such as text, images, or audio, and merging them with structured data before training a machine learning model. Text data is transformed into numerical vectors using NLP techniques like word embeddings(e.g.,Word2Vec,BERT),whileimagedatauses featureextractorslikepre-trainedCNNs(e.g.,ResNet,VGG). Audiodataisprocessedusingspectrogramsorembeddings fromRNNorCNNmodels.Theseextractedfeaturesarethen combined with structured data and fed into models like XGBoost,logisticregression,orMLPforpredictions.

Multimodal Learning

Multimodal learning that combines structured and unstructured data leverages the strengths of various data types to improve predictive power and provide more comprehensiveinsights.Inthisapproach,structureddata such as numerical values and categorical features are processed using traditional models like decision trees or neural networks, while unstructured data such as text, images, and audio are analyzed using deep learning techniques like Convolutional Neural Networks (CNNs), RecurrentNeuralNetworks(RNNs),ortransformers.These modelsarethenintegrated,oftenthroughfeaturefusionor parallelnetworks,tocreateaunifieddatarepresentation.By combining the rich, contextual information from unstructureddatawithstructureddata'sprecise,organized nature, multimodal learning enables more accurate predictions and profound insights in areas like recommendation systems, fraud detection, and medical diagnostics.

Autoencoders for Dimensionality Reduction

Autoencoders are used for dimensionality reduction by compressingunstructureddata,suchastextorimages,into

lower-dimensional embeddings,whicharethencombined with structured data. For example, compressed image embeddings in healthcare can be merged with structured datalikeageormedicalhistorytopredicthealthoutcomes. Similarly,textdatacanbecompressedandcombinedwith structured features. In a quality control system, autoencoderscompressproductimagesandcombinethem withmanufacturingdatatodetectdefects.
