Quirks in the standard processes often derail eDiscovery in Asia
- Soliton's experience makes the process fast and efficient.

Efficient and defensible eDiscovery processes for multi-byte languages cannot be achieved simply through process knowledge and skills in manipulating the data in a repeatable and transparent manner. Effective eDiscovery requires an advanced understanding of multi-byte codepages, programs unique to Asia, each language's linguistic structures, and many other details that directly impact eDiscovery or forensic investigation.


Chines & Japanese language fluency

The right seach

Soliton reduces data filtering risks by recommending synonyms, industry specific terminology and slang.  In addition, for Japanese, we can propose variants of "spelling" for the different Japanese character sets.

Relevant data

Soliton removes false positives and locates false negatives through a combination of keyword and concept search methods.  For clients ready to use advanced tools, Soliton Cyber & Analytics understands the limitations of Concept Analyzers, Predictive Coding and other advanced review tools to that these time-saving tools may be applied without loss of accuracy or defensibility.

No wasted time

Improved accuracy reduces overall data size, but more importantly, more relevant data means less wasted review time.


IT and technical expertise

Minimize garbled text

Unicode is only one of eight popular multi-byte code pages used in Japan and four popular code pages used in countries that use Chinese writing (China, Hong Kong, Singapore, Taiwan, etc.).  Soliton's extensive technical knowledge minimizes processing errors so reviewers do not waste time trying to understand garbled documents or waiting for them to be reprocessed.

Minimize processing delays

A few software programs (Microsoft Office, for example) may dominate the USA, but Japan still uses many different legacy or proprietary software for e-mail systems and Microsoft Office equivalents.  Soliton rapidly identifies and processes obscure e-mail systems and file types to reduce delays in processing data correctly.

IT Experience

Soliton's Forensic collection teams have extensive IT experience and communicates with the client's IT team in Chinese, English or Japanese as required to minimize errors.  We conduct surveys and interviews in advance so that there are no surprises for anyone.


eDiscovery best practices expertise


In addition to the technical expertise necessary to handle the unique IT issues (see above), Soliton ensures the data is properly extracted from compressed files (.zip, etc.) and prepared for input into the processing software. Although many software packages process compressed files very well for English systems, the use of 8 different code pages and double byte variances sometimes prevent files from loading correctly using these automated processes. We understands these limitations and have proprietary tools to minimize garbled data and reduce time spent reloading the data.


Even if a full-drive collection has been done to preserve evidence defensibility or to minimize recollecting data for a changing scope, clients hate paying to process program files (.exe files, Microsoft Office programs, etc.) and other junk. Soliton uses file extensions and file directory filtering to identify the data desired for the matter before it is loaded into the processing platform.

Client status reports

Soliton can report the number of files received and processed at each stage (collections, pre-processing, processing). We quickly report error reports and provide customers with options to address those exceptions. During the indexing process, we provide reports of files by custodian, hits per search item (word, phrase, etc.), and details of the reviewable contents. During this process, Soliton can also recommend additional proximity or Boolean combinations to reduce false positives and improve the quality of the selection of documents required for review.

Culling during indexing and processing

In addition to language-oriented issues, Soliton can use domain filtering to remove personal e-mails, junk mail and other noise from the review process. We document and provide transparent visibility of the options and processes used to cull data to ensure defensibility while reducing time wasted on reviewing SPAM, personal e-mail and other noise.

Review acceleration

Once the data has been indexed and processed the legal review begins, Soliton offers platforms that include non-linear review capabilities to accelerate the review process. Two of the more common methods are e-mail threading and near duplicate document search, however, concept analysis and predictive coding have also started to become more widely used.  Soliton's experience and testing of several different tools has provided us with an understanding of the limitations of these tools when applied to Chines and Japanese languaged documents and we may recommend the additional steps or QC necessary to compensate for these limitations. For more details see our use cases.
