Enriched with artificial intelligence

Huge amounts of data are a challenge for companies. Insight engines help here by using AI-based technologies. They capture information from the available data, extract relevant facts and place them in relation to one another.

Modern machines and systems require a high financial outlay. In addition to acquisition and operating costs, this also includes maintenance costs. Companies that skimp on maintenance or neglect it risk expensive production downtime. Non-fulfilment of orders can result in contractual penalties. The necessary maintenance intervals also need to be well planned in order to achieve the shortest possible downtimes. In order to achieve this and prevent malfunctions, technologies based on artificial intelligence are already available today that enable predictive maintenance, demand planning and prudent spare parts management. This is referred to as 'predictive maintenance'.

Machine learning, a sub-discipline of artificial intelligence, can be used to record and analyze process and production data from machines and systems and identify any deviations that are outside the tolerance limit. Maintenance information such as the time to replace a wearing part can also be calculated. Such intelligent data analyses allow the risk of long-term machine failures to be reduced to a minimum.

The challenge of big data

A major challenge in these analyses is the huge amount of data that has been generated by increasing digitalization and continues to be generated every second. Modern technologies from the field of artificial intelligence in combination with powerful hardware make it possible to analyze and link stored information across data sources, specialist departments and company locations. So-called insight engines meet precisely these requirements. They use AI-based technologies such as web harvesting, entities, machine and deep learning or other methods to capture information from existing data volumes, extract relevant facts and place them in relation to one another. The aim is to link information. Instead of a partial view, this creates an overall picture. Essentially, the characteristics of an insight engine can be described as follows:

  • Natural: search queries can be formulated in natural language. The insight engine interprets the query and returns the corresponding search results.
  • Comprehensive: All relevant data sources are connected via connectors.
  • Relevant and in context: Additional information is returned for the search queries that was not explicitly searched for but is relevant in context based on an autonomous analysis. Insight engines provide information immediately and proactively in the right context.
  • Benefit: Insight engines create real competitive advantages and can be used in all areas of the company.

Insight engines make it easier to handle large volumes of data and thus provide the ideal basis for generating added value from existing data.

The starting point

The task of insight engines is to find information and make it usable. In contrast to traditional search engines and search technologies, they are no longer limited to the typical search field and result.
limited. Forms of artificial intelligence offer users the opportunity to interact with the information. The technology extracts the currently required facts from all of the company's data, regardless of whether the information is structured or unstructured, and enriches it with additional information thanks to semantic analysis. At the same time, the application ensures that users only see the data for which they are authorized.

Because information is stored both in various applications within the company and in the cloud, all company data sources serve as a database. Otherwise, isolated solutions are created, which in turn mean additional work for the user.

With the help of connectors for data sources and filters for different file formats, numerous different sources can be connected with minimal effort and integrated into the central knowledge management system. This creates a knowledge database that can be queried context-specifically and efficiently for the respective departments, such as maintenance.

In addition to structured data, companies must also be able to extract and link unstructured data - such as emails with attachments, texts, audio and video files.

Extraction of information

Different technologies are used for this purpose:

  1. Rule-based methods: Based on certain, clearly recognizable structures, so-called entity recognition can be used to determine certain patterns in the text. Predefined rules are used to assign a document type.
  2. Statistical methods: Methods such as 'latent semantic analysis' are usually used to automatically recognize existing similarities and thereby determine any content-related or semantic correlations. This analysis is often also weighted in combination with probabilities.
  3. Linguistic methods: This involves concrete language-specific characteristics such as the generation of word variants, the decomposition of compounds, the creation of synonyms and word derivations, the recognition of basic forms and the understanding of individual parts and sentences of a language.

Machine learning and artificial intelligence

With the help of machine learning, intelligent systems are able to learn from accumulated knowledge from the past. They can therefore classify and assign documents completely automatically. The self-learning algorithm optimizes the unequal treatment of categories based on sample data and thus understands similar classes of information and their category properties.

The Insight Engine scans the incoming documents, extracts and analyzes the information. It then compares this with existing and already processed documents. The intelligent solution recognizes patterns and text combinations and forwards the document to the relevant department. Manual assignment is therefore no longer necessary. As a self-learning system, the program continues to develop with every action it performs. During automatic classification, for example, the system learns not only from the training documents, but also from corrected documents. This capability is particularly useful for companies with a high volume of incoming mail. As a result, processes can be optimized and employees supported efficiently.

Interpret requests

With a 360° view of a component, all information can be viewed.

In order to make optimal use of both the extracted data and its correlations, the user's queries must be correctly understood and interpreted. The following options are available for this:

  1. Natural Language Processing (NLP):
    Human language is not always precise, as it is heavily dependent on variable factors such as technical language and dialect. Based on machine learning, NLP is concerned with understanding human language with the help of patterns and word combinations and, for example, translating, interpreting, understanding text content and ideally summarizing it in a dialog.
  2. Natural Language Question Answering (NLQA):
    NLQA enables dialog between users and the machine. Search queries no longer consist of mere keywords, but can be interpreted and understood linguistically with the aim of identifying the user's needs in the right context and tailoring search results accordingly.

The visualization of the data is completely customizable. Search Apps' can be used to personalize the display based on user roles, departments or even behaviour and expertise in a 360° view of the information.

Context-specific display

It is essential that these apps are designed to be extremely user-friendly. This means that users who know the information requirements but have no programming knowledge can easily create individual display models themselves.

Nevertheless, it is always ensured that only people with the appropriate rights receive the desired information.

Goal: Pooling and providing knowledge

Artificial intelligence is already incorporated in many applications in various forms today. Intelligent technologies help companies to operate much more flexibly, faster and at a higher quality level. They bundle the existing knowledge in the company into a 360° view, extract the relevant facts and make them available in their entirety.

By comprehensively linking internal and external company information, intelligent systems are therefore also able to provide information on the expected service life of components or systems.
