CheNER: chemical named entity recognizer
MOTIVATION Chemical named entity recognition is used to automatically identify mentions to chemical compounds in text and is the basis for more elaborate information extraction. However, only a small number of applications are freely available to identify such mentions. Particularly challenging and useful is the identification of International Union of Pure and Applied Chemistry (IUPAC) chemica...
متن کاملA Biological Named Entity Recognizer
In this paper we describe a new named entity extraction system. Our system is based on a manually developed set of rules that rely heavily upon some crucial lexical information, linguistic constraints of English, and contextual information. This system achieves state of art results in the protein name detection task, which is what many of the current name extraction systems do. We discuss the n...
متن کاملStatistical Named Entity Recognizer Adaptation
Named entity recognition (NER) is a subtask of widely-recognized utility of information extraction (IE). NER has been explored in depth to provide rapid characterization of newswire data (Sundheim, 1995; Palmer and Day, 1997). The NER task involves both identification of spans of text referring to named entities, and categorization of these entities into classes based on the role they fill in c...
متن کاملNEROC: Named Entity Recognizer of Chemicals
We describe a pipeline system, Named Entity Recognizer of Chemicals (NEROC), that aims to identify chemical entities mentioned in free texts. The system is based on a machine learning approach, a Conditional Random Field (CRF), and a selection of feature sets that are used to capture specific characteristics of chemical named entities. In this paper, we report results that produced by CRF model...
متن کاملA Named Entity Recognizer for Filipino Texts
In this paper, we define the task of named entity recognition, look at existing systems for named entity recognition, and discuss the design, implementation, and evaluation of a system that performs named entity recognition on Filipino texts. We also compare the results of the system with an existing named entity recognizer designed for English texts using a Filipino corpus.
