Knowledge Graph Technology: An Overview

What is Knowledge Graph Technology, and how does it work?

A knowledge graph is a knowledge base that collaborates closely using a graph-structured dataframe or structure. Knowledge networks are typically used to store interconnected descriptions of elements with free-form semantics, such as objects, events, circumstances, or abstract concepts.

Knowledge Graphs are useful in a number of situations. Most people, on the other hand, are still unfamiliar with Knowledge Graphs and the underlying graph databases, and because of the technology’s seamless integration into our lives, they are unaware of how reliant humans have become on it or how they have come to expect a certain level of quality and standard from it.

Knowledge Graph Technology has a variety of properties, including database, where data can be examined using structured queries, graph, where data can be analysed like any other network data structure, and knowledge base, where data can be interpreted and new facts inferred using formal semantics.

Applications of Knowledge Graph Technology

Berners-Lee advocated for the promotion and development of technical standards such as the Uniform Resource Identifier (URI), Resource Description Framework (RDF), and Web Ontology Language (OWL) in his work. Using the RDF standard in the early days, some researches helped to advance the graph-based representation of knowledge. In such graphs, nodes represent entities, and edges represent relationships between them.

A schema or ontology can be used to structure the sets of relations, defining their correlativity and usage limits.

In 2009, the concept of Linked Data was introduced. It is proposed that diverse datasets in the Semantic Web be linked together so that they can be viewed as one single, global knowledge graph. Until 2014, the Linked Open Data cloud had roughly 1,000 datasets linked to each other, with the majority of the links connecting identical entities.

Several firms are already utilising Knowledge Graph technology to remain ahead of the competition. Graph databases and knowledge graphs have been utilised in banking, the auto industry, oil and gas, pharmaceutical and health care, retail, publishing, and the media, to name a few industries.

Although these firms have different goals in mind when they employ Knowledge Graphs, the end goal is the same: to add value to large volumes of data from diverse data silos so that it may be used (and eventually re-used) in a more meaningful and intelligent way.

The most important applications are listed below.

IT Services

Governmental Organizations

Medical Field

This makes it easier for doctors and service providers to identify the data they require among the many variables and data sources.

Deep Learning Based

Without depending on hand-crafted features and rules, multi-column convolutional neural networks (MCCNNs) were utilised to retrieve information.

They rank candidate responses using a score layer based on question and candidate answer representations. An end-to-end neural network model that assesses multiple potential answer features to represent the questions and their associated scores incorporated a cross-attention mechanism.

The knowledge base is considerably separated from traditional techniques to semantic parsing. They compress semantic parsing to query graph generation and present it as a staged search issue to make full use of the knowledge in knowledge bases, inspired by information retrieval and embedding methods.

They also use a deep convolutional neural network (CNN) model to exploit the knowledge base early on to trim the search space, making the semantic matching problem easier to solve.

When employing the embedding strategy, an attention-based bidirectional long short-term memory (BiLSTM) was used to learn the representations of the questions. The results of the experiments suggest that their method is effective and capable of expressing the correct information of inquiries.
