Knowledge based systems text analysis

The astronomically immense number of potential applications from bridging Web data with cognizance bases has led to an incrementation in the entity linking research. Entity linking is the task to link entity mentions in text with their corresponding entities in a knowledgebase. Potential applications include information extraction, information retrieval, and cognizance base population. However, this task is challenging due to designate variations and entity ambiguity. In this survey, we present an exhaustive overview and analysis of the main approaches to entity linking, and discuss sundry applications, the evaluation of entity linking systems, and future directions.
