Abstract:Abstract-An important amount of clinical data concerning the medical history of a patient is in the form of clinical reports that are written by doctors. They describe patients, their pathologies, their personal and medical histories, findings made during interviews or during procedures, and so forth. They represent a source of precious information that can be used in several applications such as research information to diagnose new patients, epidemiological studies, decision support, statistical analysis, and… Show more
“…Once the preprocessing step completed we obtain a vector representation with binary weighting for the 9 documents presented in table 1, which will represent the formal context. [18,19] is a cellular Automaton that is made of two finite arbitrary long layers of finite state machines (cells) that are all identical. The operation of the system is synchronous, and the state of each cell at time t+1 depends only on the state of its vicinity cells, and on its own state at time t. This automaton, simulates the functioning of the basic cycle of an inference engine by using two finite layers of finite automata.…”

“…The dynamics of the cellular automaton BIG [1,23], to simulate the operation of an Inference engine uses two functions of transitions δ fact and δ rule , where δ fact corresponds to the phase of assessment, selection and filtering, and δ rule corresponds to the execution phase [1,24]. To set the two functions of transition we will adopt the following notation: EF, IF and SF to designate CELFACT_E, _I and _S; Respectively ER, IR and SR to designate CELRULE_E, _I and _S.…”

“…In this section, we present the principles of construction, by Boolean modelling [1,5,9,23,24], of induction graphs in the problems of discrimination and classification [1,2] : we want to explain the class taken by one variable to predict categorical Y, attribute class or endogenous variable; from a series of variables X 1 , X 2 ,..., X p , say variable predictive (descriptors) or exogenous, discrete or continuous. According to the terminology of machine learning, we are therefore in the context of supervised learning.…”

-Information Extraction (IE) is a natural language processing (NLP) task whose aim is to analyze texts written in natural language to extract structured and useful information such as named entities and semantic relations linking these entities. Information extraction is an important task for many applications such as bio-medical literature mining, customer care, community websites, and personal information management. The increasing information available in patient clinical reports is difficult to access. As it is often in an unstructured text form, doctors need tools to enable them access to this information and the ability to search it. Hence, a system for extracting this information in a structured form can benefits healthcare professionals. The work presented in this paper uses a local grammar approach to extract medical named entities from French patient clinical reports. Experimental results show that the proposed approach achieved an F-Measure of 90. 06%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
