Therefore, when applying computational semantics, automatic processing of semantic meaning from texts, domain-specific methods and linguistic features for accurate parsing and information extraction should be considered. Compositionality in a frame language can be achieved by mapping the constituent types of syntax to the concepts, roles, and instances of a frame language. For the purposes of illustration, we will consider the mappings from phrase types to frame expressions provided by Graeme Hirst[30] who was the first to specify a correspondence between natural language constituents and the syntax of a frame language, FRAIL[31]. These mappings, like the ones described for mapping phrase constituents to a logic using lambda expressions, were inspired by Montague Semantics. Well-formed frame expressions include frame instances and frame statements (FS), where a FS consists of a frame determiner, a variable, and a frame descriptor that uses that variable. A frame descriptor is a frame symbol and variable along with zero or more slot-filler pairs.

The most crucial step to enable semantic analysis in clinical NLP is to ensure that there is a well-defined underlying schematic model and a reliably-annotated corpus, that enables system development and evaluation. It is also essential to ensure that the created corpus complies with ethical regulations and does not reveal any identifiable information about patients, i.e. de-identifying the corpus, so that it can be more easily distributed for research purposes. We present a review of recent advances in clinical Natural Language Processing (NLP), with a focus on semantic analysis and key subtasks that support such analysis. Expert.ai’s rule-based technology starts by reading all of the words within a piece of content to capture its real meaning. It then identifies the textual elements and assigns them to their logical and grammatical roles.

Knowledge Base Collecting Using Natural Language Processing Algorithms

NLP combines computational linguistics—rule-based modeling of human language—with statistical, machine learning, and deep learning models. Together, these technologies enable computers to process human language in the form of text or voice data and to ‘understand’ its full meaning, complete with the speaker or writer’s intent and sentiment. Modern NLP involves machines’ interaction with human languages for the study of patterns and obtaining meaningful insights. In this survey, we outlined recent advances in clinical NLP for a multitude of languages with a focus on semantic analysis. Substantial progress has been made for key NLP sub-tasks that enable such analysis (i.e. methods for more efficient corpus construction and de-identification). Furthermore, research on (deeper) semantic aspects – linguistic levels, named entity recognition and contextual analysis, coreference resolution, and temporal modeling – has gained increased interest.

The parser was trained on a corpus of general Finnish as well as on small subsets of nursing notes. Best performance was reached when trained on the small clinical subsets than when trained on the larger, non-domain specific corpus (Labeled Attachment Score 77-85%). To identify pathological findings in German radiology reports, a semantic context-free grammar was developed, introducing a vocabulary acquisition step to handle incomplete terminology, resulting in 74% recall [39]. A consistent barrier to progress in clinical NLP is data access, primarily restricted by privacy concerns. De-identification methods are employed to ensure an individual’s anonymity, most commonly by removing, replacing, or masking Protected Health Information (PHI) in clinical text, such as names and geographical locations.

This challenge is a frequent roadblock for artificial intelligence (AI) initiatives that tackle language-intensive processes. With its ability to quickly process large data sets and extract insights, NLP is ideal for reviewing candidate resumes, generating financial reports and identifying patients for clinical trials, among many other use cases across various industries. With the Internet of Things and other advanced technologies compiling more data than ever, some data sets are simply too overwhelming for humans to comb through. Natural language processing can quickly process massive volumes of data, gleaning insights that may have taken weeks or even months for humans to extract.

The natural language processing involves resolving different kinds of ambiguity. That means the sense of the word depends on the neighboring words of that particular word. Likewise word sense disambiguation (WSD) means selecting the correct word sense for a particular word. WSD can have a huge impact on machine translation, semantic analysis in natural language processing question answering, information retrieval and text classification. Natural language processing (NLP) is an area of computer science and artificial intelligence concerned with the interaction between computers and humans in natural language. The ultimate goal of NLP is to help computers understand language as well as we do.

Resources are still scarce in relation to potential use cases, and further studies on approaches for cross-institutional (and cross-language) performance are needed. Furthermore, with evolving health care policy, continuing adoption of social media sites, and increasing availability of alternative therapies, there are new opportunities for clinical NLP to impact the world both inside and outside healthcare institution walls. ICD-9 and ICD-10 (version 9 and 10 respectively) denote the international classification of diseases [89].

People will naturally express the same idea in many different ways and so it is useful to consider approaches that generalize more easily, which is one of the goals of a domain independent representation. NLP-powered apps can check for spelling errors, highlight unnecessary or misapplied grammar and even suggest simpler ways to organize sentences. Natural language processing can also translate text into other languages, aiding students in learning a new language. Natural language processing can help customers book tickets, track orders and even recommend similar products on e-commerce websites.

Semantic Building Blocks – Extracting Meaning From Texts

The adapted system, MedTTK, outperformed TTK on clinical notes (86% vs 15% recall, 85% vs 27% precision), and is released to the research community [68]. In the 2012 i2b2 challenge on temporal relations, successful system approaches varied depending on the subtask. Clinical NLP is the application of text processing approaches on documents written by healthcare professionals in clinical settings, such as notes and reports in health records. Clinical NLP can provide clinicians with critical patient case details, which are often locked within unstructured clinical texts and dispersed throughout a patient’s health record. Semantic analysis is one of the main goals of clinical NLP research and involves unlocking the meaning of these texts by identifying clinical entities (e.g., patients, clinicians) and events (e.g., diseases, treatments) and by representing relationships among them. There has been an increase of advances within key NLP subtasks that support semantic analysis.

With its ability to process large amounts of data, NLP can inform manufacturers on how to improve production workflows, when to perform machine maintenance and what issues need to be fixed in products. And if companies need to find the best price for specific materials, natural language processing can review various websites and locate the optimal price. Healthcare professionals can develop more efficient workflows with the help of natural language processing. During procedures, doctors can dictate their actions and notes to an app, which produces an accurate transcription. NLP can also scan patient documents to identify patients who would be best suited for certain clinical trials.
