Unified Services and Pluszero have joined forces to Developed Chat-GPT service that dramatically improves search and summary accuracy

Integrated collaboration service combining AI-OCR, Chat-GPT, and Knowledge Graph technologies Sales to DX promotion departments to begin sequentially from October 2023


Unified Services Corporation (headquartered in Minato-ku, Tokyo; Eiji Uda, President & CEO; hereinafter "Unified Services"), a provider of industry cloud and digital marketing services, and pluszero, a provider of solutions, development, maintenance, and operation of various technologies such as AI and natural language processing, have jointly announced a new partnership to improve the accuracy of mass document summary. (Headquarters: Setagaya-ku, Tokyo; Chairman and CEO: Yoshiyuki Ojiro / President and COO: Ryota Mori; hereinafter "pluszero"), which provides, develops, maintains, and operates various technology solutions such as AI and natural language processing, have successfully developed the AI Search & Summary Service (AI-3S), a service that dramatically increases the accuracy of mass document summary and links it to search. Combining the AI search service "Encourage Japan" provided by Unified Services and pluszero's AI technology and implementation capabilities, the service analyzes large volume documents containing special characters and atypical text, summarizes them using AI, instantly generates summarized sentences, and returns a response based on an understanding of the searcher's intent.

Compared to the Large Language Models that are rapidly gaining popularity today, which learn a wide range of information, this service searches and summarizes target information in advance, making it possible to provide more reliable and accurate information, and to understand specialized and difficult-to-understand information in more understandable sentences. This service will be available by October 10, 2023. This service will be available from October 2023 through direct sales of Unified Services.

Background of Development

Together with pluszero, we have been searching for a new service that combines the features of both services. In the past few years, the digitization of business processes in Japanese companies and organizations has progressed rapidly, and at the same time, many documents have been digitized in various companies and organizations. However, although this has resulted in the preservation of more information, many companies and organizations are still unable to fully utilize their information assets. In addition, while many companies and organizations have high expectations for the use of large-scale language models (LLMs), generalized LLMs have outdated information, the spread of misinformation through AI Halcination, and ethical issues.

In an effort to quickly resolve these situations, the two companies collaborated to develop a solution for companies and organizations by combining pluszero's AI technology and Unified Services' ability to integrate a variety of services.

pluszero's highly accurate AI-OCR technology and learning model optimized for the Japanese language form the core of this service, while the Unified Service integrates the information structuring and AI search This service is realized by integrating the information structuring and AI search service functions already provided by Encourage Japan in the Unified Service.

Outline of AI Search & Summary Service (AI-3S)

There is no end to the needs of companies and organizations around the world to easily understand highly specialized information, to avoid sending out wrong information, and to improve productivity through the use of AI. This service is based on Plus Zero's technology, which has long applied natural language processing technology specifically to the Japanese language, and our company's technological capabilities to integrate (unified) existing cloud services.

The service consists of the following functions

AI-3S Overview

Document digitization function by OCR's+.

OCR's+ is an OCR service provided by pluszero. It flexibly extracts textual information from document files regardless of format, including support for atypical forms. In addition to general AI-OCR technology, natural language processing technology is applied to extract specific content from documents.

Using the information structuring function of Encourage Japan Content, the document is structured to generate a database that can be published on the Internet. The structuring also creates a situation where it is easy for AI to read. 3.

AI search function

Using the natural language analysis search service of Encourage Japan Search, queries that understand the search intent are generated in the back-end, searched against the structured data, and more accurate information is returned quickly.

Document Segmentation Function by Semantic AI

AEI (Artifitial Elastic Intelligence), a natural language processing concept originally proposed by pluszero, is used to segment documents into meaningful chunks.

5. AI summary function

The search results are further summarized into a form to be provided to the customer. The display method of summary results will be designed according to customer requests.

The service is planned to be provided in two phases.

<Phase 1 (to be launched in October 2023)

We will use pluszero's OCR's+ to digitize documents and realize multi-step summarization. In addition, AEI technology will be used to automate the semantic segmentation of large volumes of text prior to summarization.

<Phase 2 (to be launched in February 2024)

Integrate with our AI search service "Encourage Japan" to expand the summary service in response to user searches. At the same time, information will be structured.

AI-3S Service Launch Date

The AI-3S service will be offered through system integration to IT and administrative departments of medium to large companies, as well as to public agencies. Each solution is then packaged individually and offered as a SaaS (System As A Service), which the customer subscribes to on a monthly basis. In parallel with the development of individual sales activities by our sales staff, we also plan to offer a wide range of cloud services on our website.
