The invention discloses an academic achievement institution naming disambiguation method and a device based on a reliable information base, and the method comprises the steps: extracting the related information of an institution from an academic achievement text, and obtaining an institution character string; segmenting the institution character string according to the special character, naming and identifying part of entities of the segmented character string, and storing the entities belonging to entity names into a suspected institution queue; performing geographic position information mapping on the suspected organization queue to obtain organization geographic position information; performing multi-class name similarity calculation according to the reliable institution data set to obtain a suspected institution entity sequence and a corresponding highest similar name similarity value; and performing address extraction and geographic position information mapping on the suspected institution entity sequence, and screening out an optimal result through a final similarity value of a distance from the suspected institution entity sequence to the institution geographic position information and a highest similarity name similarity value. According to the method, naming disambiguation of the institutions in the academic achievements can be simply, quickly and accurately achieved,and standardization of the institution names is achieved.
Description
technical field [0001] The invention relates to the technical field of information retrieval, and in particular to a method and device for disambiguating academic achievement institution naming based on a reliable information base. Background technique [0002] The text of institutional entity information in academic achievements is relatively short, which is prone to ambiguity in expression. Reliable external information databases can provide sufficient comparative information for short texts, which provides the possibility to achieve disambiguation in the naming of institutions in academic achievements. Institution naming disambiguation based on a reliable institution information base can be applied to a variety of applications, such as the construction of an unambiguous institutional entity information base, the analysis of institutional cooperation networks, and so on. [0003] Institution names have certain exclusivity within a specific time and space, but show strong a...
