Identification of metabolite-disease associations based on knowledge graph

Metabolomics
Despite the insights that metabolite analysis can provide into the onset, development, and progression of diseases-thus offering new concepts and methodologies for prevention, diagnosis, and treatment-traditional wet lab experiments are often time-consuming and labor-intensive.

Automatic Identification of Conceptual Metaphors With Limited Knowledge

Proceedings of the AAAI Conference on Artificial Intelligence, 2013
Full natural language understanding requires identifying and analyzing the meanings of metaphors, which are ubiquitous in both text and speech. Over the last thirty years, linguistic metaphors have been shown to be based on more general conceptual metaphors, partial semantic mappings between disparate conceptual domains.

Identification of boolean control networks incorporating prior knowledge

2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017
In this paper, we investigate identification problem of Boolean control networks (BCNs) by applying the semitensor product and representing the system matrices by binary parameters. Prior knowledge can be utilized to reduce the number of binary parameters in system matrices.

A Priori Knowledge for Dynamic Identification of Robots

IFAC Proceedings Volumes, 1993
Abstract A priori information about parameters is necessary to generate exciting trajectories which improve the noise immunity of least squares estimation of inertial parameters of robot. This paper presents robust methods to obtain a priori knowledge about friction parameters, inertial parameters and drive gains, moving one axis at a time.

Knowledge identification phase of natural language analysis

1977
Case organization of verbs has provided a powerful mechanism for natural language analysis systems. However, only simple semantic-marker-like information has been used to determine the acceptibility of lexical elements as case-role fillers. Actually, this ability is influenced by more intricate relations among words.

Identification of Participants of Narratives Using Knowledge Bases

Anais do XXXIX Simpósio Brasileiro de Banco de Dados (SBBD 2024)
Identifying participants in narratives is important to understand and extract meaning from unstructured texts. This paper investigates the use of DBpedia and Wikifier for this task. We tested these two knowledge base platforms to evaluate their performance in recognizing and extracting entities in Portuguese-language journalistic narrative texts.

IDENTIFICATION OF HYBRID SYSTEMS USING A PRIORI KNOWLEDGE

IFAC Proceedings Volumes, 2002
Abstract An approach for the identification of a class of hybrid systems is presented. The identification problem for hybrid systems is formulated as an optimization problem and two possible ways for an approximative solution of the problem are discussed. As a result of this discussion a top-down algorithm for the approximative solution is developed.
