This blog post was co-authored, and consists of an intro, by Aaron Brunko, Senior Vice President, Claims Product at Xactware.
When a loss takes place, the claim representative asks for a list of involved valuables to be consisted of in the general claim submission. The list (stock) also consists of particular information such as a detailed item description (including brand and design number when readily available), where the item was bought, when it was bought, how much was paid, and a general condition and use of the product.
Take a minute and reflect on your own individual possessions. If you were asked at a moments notification to offer a comprehensive stock, you may (like many individuals) have difficulty keeping in mind how lots of button-down gown shirts you had in the closet, the variety of knives that was available in the set you purchased five years back, or the variety of sockets from the toolbox– not to mention the specifics required to correctly value and adjust your claim. Ideally, you have a digital record through photos, videos, and online shopping orders that can help you piece the puzzle together.
When your inventory is complete, you submit it to the assigned claim representative, who systematically identifies protection based upon the terms of your insurance coverage and begins assessing the inventory. The stock is in a digital format, which can be imported directly into an estimating application where the claims agent will match each item with a product of depreciation, like-kind, and quality based on department, life expectancy, age, and condition.
When the claim agent completes the evaluation, they prepare payment letters and offer you with payment of the actual cash worth (most common) less your deductible and any quantities over your policy limitations. If your policy enables recoverable depreciation, you require to supply proof of purchase to collect the distinction in between the replacement expense and real money value.
In brief, this laborious procedure can take months or even years until the last item is changed and final payment is issued.
To further highlight this point, Xactware Solutions assisted process more than one million personal effects claims between 2019 and 2020, totaling over 17 billion dollars of replacement cost worth. Throughout this time, more than 4.5 million products were recorded in the claims system, which took 37.76 days typically from when a claim was produced till the last recognized modification. In 2020 alone, the average days were 44.56 and the average number of corrections to the file were 1.01 (meaning on typical each price quote had actually to be remedied a minimum of one time).
As a senior executive of a big US-based insurance company as soon as put it, “We are all getting a stopping working grade in the market when it pertains to personal home settlement. There is much improvement that can be made to enhance claims of all sizes and shapes, to better enhance the policyholder experience, and at the very same time minimize overhead expenses for market.”
The relationship showed in the following charts between the variety of items, days to closure (last estimate upload), and number of corrections highlight clusters use excellent starting points for us to move the needle in the best direction.

Automated claims processing
With developments in analytics technology such as seamless shopping made it possible for by online retail and supply chain performances, numerous consumers seek a likewise seamless experience when handling home insurance claims.
To resolve this growing opportunity, Xactware has actually made it a top organizational priority to enhance the claims journey for the insurance policy holder, with the concurrent aim of lowering the expenses of claim servicing for insurance providers.
To deliver on these priorities, Xactware has set out a holistic vision of automating the claims lifecycle from start to end up throughout the claims workflow. Artificial intelligence (ML) is an essential technology to meet this end, and enables:
Streamlining the First Notice of Loss (FNOL) process
Automating the collection of loss details
Automating the decision-making and evaluation of replacement items
Processing digital payments to declare filers.
To this end, Xactware engaged the Amazon ML Solutions Lab to help start the ML journey. Together they identified 2 high worth organization usage cases that were picked to develop two options showing making use of ML to satisfy these goals.
Both usage cases focused on automating the classification and line product matching of items that get sent by a claim filer or insurance policy holder as part of a loss claim, such as submitting a list of products that were stolen in a theft– a labor-intensive action in the workflow that a claims adjustor usually finishes by manually querying and choosing products from a prospect items database covering thousands of products. This automation is expected to further make it possible for the automation of item lookups of a similar kind and quality and their associated depreciation schedules, which are two crucial aspects that insurers need in order to obtain the replacement expense worth and diminished total up to be factored for payment to the insurance policy holder.
Specifically, these 2 usage cases consisted of:
Now that we understand the macroscopic homes of the data, we consider the particular contents of each sample. In addition to the user-input text description of a product, we likewise have user-input text descriptions of the space in which the product was lost– and how it was lost (such as fire, theft, or flooding). Our training information is text, for which predictive analytics are ideal to be developed on natural language processing (NLP) ML algorithms. Rather than build a model from scratch, which would need considerable information preparation (stemming, tokenizing), pretraining (language corpus, vectorizing) and facilities management (setting up training and reasoning circumstances), we can utilize Amazon Comprehend, which manages the undifferentiated heavy lifting of the ML cycle and is trained by a group of specialized NLP specialists.
To produce optimal results stabilized with an effective use of hardware resources, Amazon Comprehend restricts custom-made category models to 1,000 special labels. Provided our nearly 4,000 labels, we developed 4 different category models that, in aggregate, provide us with the forecasted class of a line product.
For each CatSel, we can examine how the design performs. That is, we pass all circumstances of the real label through the models for inference and tape the prediction. After looping through all CatSel labels, we wind up with a set of F1 ratings that we can then bin and plot as a pie chart to visualize model performance across CatSels.
Product category– Using ML to properly categorize products based on the text descriptions gotten in by the policyholder into the appropriate categories and selectors (subcategories), which together span nearly 4,000 combined classes
Offered the efficiency circulation across CatSels, we now have a sense of confidence around how accurate a given forecast is. When the design forecasts a label on which the models carry out well, we can automate the rest of the insurance coverage claim pipeline with low expectations of error. For other labels, we can continue the manual procedure of evaluation while gathering additional information to feed back into the model for training and eventually improve predictions across the board.
Following the effective identification of the appropriate category or class to which the described product belongs (based on the category code and the selector code, CatSel), the attention of the claim processing pipeline shifts to identification of the real product (its make, its model, and so on) that the policyholder has filed a claim for. Generally, the sent item description might match with lots of similar items.
The item-matching DNN model was built utilizing PyTorch. We made usage of FastText (and BERT) embeddings for dealing with text. The final version utilizes FastText embedding alone since utilizing BERT embeddings didnt produce any considerable enhancement over the FastText embedding for this usage case, and generating FastText embeddings is less computationally extensive, therefore quicker. The overall architecture of the item-matching DNN model is summarized in the following figure.
The list (inventory) also consists of specific details such as a detailed product description (consisting of brand and model number when available), where the product was acquired, when it was bought, how much was paid, and a basic condition and use of the product.
Following the successful identification of the proper category or class to which the described item belongs (based on the category code and the selector code, CatSel), the attention of the claim processing pipeline shifts to recognition of the real product (its make, its design, and so on) that the insurance policy holder has actually filed a claim for. Essentially, the DNN model takes in the details of the item in the claim and the info of the items from the database that could potentially be the proper match. In the present case, just the location of the appropriate product (favorable matched product) is crucial, and the relative places of all the negative products (that must not be picked, and which make up 99 of 100 shortlisted items) is of little interest. As an option to NDCG, you could also compare two lists of the items, obtained from 2 independent arranging methods, by looking at the typical place of the correct product (the average location of the item of interest) in the sorted lists.

The initial step to building an automated claims processing pipeline is to correctly recognize the high-level class to which the item belongs. An adjustor might query with the description “2015 kindle 4gb” as the product description and get a list of prospect products. To narrow down this list, we begin by constructing a model that changes the inquiry into an exact group of products; in this case, the group is e-readers.
Throughout the years with deep experience in the insurance market, Xactware has developed a database of products including everything from Amazon Kindles to satin sheets. These products are categorized according to their category and subcategory, called the selector. By determining the generic CatSel (category-selector sets), we can improve the item match according to brand name and design as explained in the next area in this post. An example CatSel pair would be ELC-CPHN for the “cellular phone” selector belonging to the “electronic devices” classification class.
Jewelry and clothing are much more likely to appear on a claims form than an antique armoire or a musical instrument. We can make efforts to rebalance the dataset, the underlying qualities of the information are such that we expect design performance to vary by label.
In this post, we talked about such an endeavor that integrates NLP through a multi-class classifier developed on text functions and a multimodal branched deep neural network acting as a ranker for refining product matches. We anticipate a 75% decrease in claims processing time through this ML-assisted claims processing compared to manual product matching.
As Xactware continues to invest in ML and checks out extra opportunities for efficiency gains, we can look with certainty for future developments in the insurance space.

Customer and organization impact
After implementing the designs for use in real-time reasoning, we replicate the insurance policy holders journey of filling out a digital insurance coverage claim when assisted with instantaneous forecasts. The outcome of shows that the designs trained by the ML Solutions Lab can instantly match 75% of products got in into the kind, whereas the existing system matches at 25%.
With the current service, it took 4 minutes to manually find the proper CatSel for 20 items. With the ML models developed by the ML Solutions Lab, the Verisk team anticipates this taking no greater than 1 minute to spot check and fix 6 products, because all 6 had the proper description in a minimum of the top three results. With auto-approval of high-confidence items from the design, together with spot-checking less confident forecasts, they expect a boost in the accuracy and speed of classifying products by 300%.
The benefit to users of Xactware software is that they experience a quicker, simpler, and more precise platform when carrying out their work. Consumers experience much shorter wait times in between their claims filing and product replacement or compensation.
In the following figure, we present an early rendition of the software application UX that can be provided to insurance adjustors. As the user goes into the item description, the cost, classification, and selector fields are automatically filled utilizing of the designs described previously. Along with the forecasts is a confidence ranking to help in a quick handbook evaluation.
Essentially, the DNN design takes in the details of the item in the claim and the information of the items from the database that might possibly be the right match. This number is an approximated possibility that the product from the search API is the correct item for the filed claim. If the approximated possibilities (and for that reason the arranged list of matched products) are ideal, you can anticipate that the right item ranks initially and appears in the very first place of the sorted list.
In the current case, only the location of the proper product (favorable matched item) is essential, and the relative locations of all the negative products (that must not be picked, and which make up 99 of 100 shortlisted products) is of little interest. As an option to NDCG, you might also compare two lists of the items, gotten from 2 independent arranging approaches, by looking at the average place of the right product (the average location of the item of interest) in the arranged lists.
In general, the DNN model carried out well and reduced the typical position of the appropriate outcome from 10 (in the Search API) down to 2, as displayed in the following charts. By making it easy to locate the correct item, this item-matching model and pipeline has the prospective to decrease the time required for claims processing by a factor of 5 or by 500%.
