It accomplishes this by serving as a standardized framework that organizes and abstracts organizational knowledge and data (structured, unstructured, semi-structured). This defines common business terms and relationships, thereby enabling data mapping and interpretation across all organizational knowledge assets.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The foundational step to getting started with a Semantic Layer begins with a practical approach to data mapping, cleansing, reconciling, relationship establishment, and governance. While many of these steps are rather straightforward data transformation work, reconciling real-world entities (who is who) while revealing hidden connections (who is related to who) has remained a vexing challenge.\u00a0<\/span><\/p>\n<h2><\/h2>\n<p>&nbsp;<\/p>\n<h2><strong>Entity Resolution: The Secret Weapon\u00a0<\/strong><\/h2>\n<p><strong><a href=\"https:\/\/senzing.com\/what-is-entity-resolution\/\" target=\"_blank\" rel=\"noopener\">Entity Resolution<\/a><\/strong><span style=\"font-weight: 400;\"> is a process that determines if multiple <\/span><i><span style=\"font-weight: 400;\">apparently different <\/span><\/i><span style=\"font-weight: 400;\">database records actually represent the same real-world entity (e.g., person, organization, vehicle).<\/span><span style=\"font-weight: 400;\"> In the image below note the many differences between the first two records. Despite these differences, Entity Resolution allows one to reasonably conclude that they represent the same individual entity.<\/span><\/p>\n<p><a href=\"https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/EntitiesV2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-20508 size-full\" src=\"https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/EntitiesV2.jpg\" alt=\"Example of entity resolution, comparing two records for Will J Smith and William Smith Jr - finding they are related and are both William Smith Sr.\" width=\"1200\" height=\"305\" srcset=\"https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/EntitiesV2.jpg 1200w, https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/EntitiesV2-336x85.jpg 336w, https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/EntitiesV2-771x196.jpg 771w, https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/EntitiesV2-768x195.jpg 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/a><\/p>\n<p><span style=\"font-weight: 400;\">At the same time, Entity Resolution must be able to detect when records containing very similar information are, in fact, different real-world entities. Note in the above image, the only difference between records two and three is one character: \u201cJ\u201d vs \u201cS\u201d (Junior vs. Senior). It is quite interesting that the record on the left can be confidently called the same person, while the person on the right is clearly a different person. Discovering relationships between entities (connectedness) is what should be a fundamental aspect of your Entity Resolution technology.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While various technologies perform this task of Entity Resolution, they are referred to &#8211; quite ironically &#8211; by different names such as link detection, record matching, or identity resolution. This term can also be named after a specific mission such as patient record matching, debtor matching, or profile unification (often associated with marketing use cases).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Whether organizations opt to purchase or develop in-house Entity Resolution solutions, precision remains paramount. Additional key factors to consider include things such as batch or real-time processing, scalability (i.e. does the organization have 20 thousand records or 10 billion records to process), ease of use, multi-language support, and explainability.<\/span><\/p>\n<h2><\/h2>\n<p>&nbsp;<\/p>\n<h2><strong>Role of Entity Resolution and a Semantic Layer\u00a0<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">A <\/span><strong><a href=\"https:\/\/enterprise-knowledge.com\/what-is-a-semantic-architecture-and-how-do-i-build-one\/\">Semantic Layer architecture<\/a><\/strong><span style=\"font-weight: 400;\"> typically employs a variety of solutions and technologies aimed at providing a unified and understandable view of data across different sources.

Baking Entity Resolution early in the process of data modeling facilitates scaled data integration while ensuring consistency and quality of the data represented within a Semantic Layer. Furthermore, it provides a unified view of data enhancing search and discovery &#8211; ultimately improving performance and speed of analytics and data engineering.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In the context of creating an ERKG, it is essential to choose a method that not only identifies matches but also uncovers hidden connections between records that may only contain one similar attribute (e.g. same address despite messy representation). In this scenario, what you want is Entity Resolution that can reveal non-obvious connections between records. For example, two records sharing only this address feature should be surfaced to the knowledge graph as connected or related entities.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Entity Resolution brings clarity by converting what one might call a \u201cdata graph\u201d into a knowledge graph. While duplicate nodes are collapsed\/consolidated, new or previously unseen relationships between entities are revealed. The image below illustrates the transition from a knowledge graph to an ERKG.\u00a0<\/span><\/p>\n<p><a href=\"https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/image-22.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-20510\" src=\"https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/image-22.png\" alt=\"\" width=\"1279\" height=\"659\" srcset=\"https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/image-22.png 1279w, https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/image-22-336x173.png 336w, https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/image-22-771x397.png 771w, https:\/\/enterprise-knowledge.com\/wp-content\/uploads\/2024\/05\/image-22-768x396.png 768w\" sizes=\"auto, (max-width: 1279px) 100vw, 1279px\" \/><\/a><\/p>\n<p><span style=\"font-weight: 400;\">A well-engineered ERKG is scalable and adaptable to evolving data requirements.
