Increasing Consistency and Trust in Documents

Fast Contrast: Deloitte's text comparison tool

Checking for conceptual similarities and inconsistencies is a critical step before publication of important documents or reports – for credibility and compliance reasons. Deloitte’s Fast Contrast automates this process, providing a flexible semantic tool that rapidly compares documents and presents findings in an intuitive, flexible interface.

The need for a comparison tool

In the digital age, it is common for documents to be stored centrally and accessible to everyone. These documents may be edited by several people simultaneously, or information can be copied from one document to another. In this case, the origin of the information is no longer traceable. Throughout this process, small errors can creep in, buried within a single document – or scattered across many documents. Depending on the purpose of the documents, the cost of errors may range from embarrassment (marketing) to non-compliance (regulatory submissions) or latent risks and liabilities (contracts). Finding such errors – gaps vs. regulations, or inconsistencies between similar documents – can be a challenge. Especially when documents are lengthy and require qualified staff to appreciate the links between topics that may be worded quite differently. Hiring well-paid experts to reconcile documents is an expensive and error-prone proposition.

Conversely, similarity rather than inconsistency is a risk if plagiarism is to be avoided. Simple filters may find word-for-word intellectual piracy, but they will be fooled by texts where the author purposefully rephrased passages to escape detection. Detecting plagiarism requires comparison to a wide range of topically related works – an even more time-consuming task than searching for consistency between a limited number of documents. Inevitably, the question arises: who can perform all this work?

 

 

Our solution: Fast Contrast

Therefore, Deloitte provides the document comparison tool "Fast Contrast" in order to resolve this task in an efficient and problem-oriented way. This tool combines advanced Natural Language Processing (NLP) and a user-friendly interface to address the challenges described above. The typical use case for Fast Contrast is to base its comparison on a selected "trusted" document, which should be trustworthy and error-free. Fast Contrast automatically detects the language of the texts (base functionality: German and English, extendable to other languages).

The subsequent document comparison is performed on sentence level, where semantically similar sentences are additionally checked for numerical differences. The result is a sentence-level similarity score, accompanied by the corresponding text excerpts – displayed both in a ranking table as well as rendered directly on the source document (PDF). Fast Contrast comes pre-trained for general use. It can be further trained to incorporate industry or subject-matter vocabulary, further improving its reliability in analyzing specialist content. Users can submit a large number of documents to Fast Contrast for batch-processing.
