[Objective] This paper proposes a model to classify institutions in Wikidata’s category trees, aiming to better organize these entities. [Methods] We used an unsupervised hierarchical clustering algorithm to automatically cluster the institutional instances without proper tags. To eliminate the influence of the co-occurring feature words, we introduced the relevant attributes of the organizational entities in Wikidata. The clustering algorithm is sensitive to the data dimensions, hence, used the Latent Semantic Index to represent the texts. We also mapped the high-dimensional data to the potential low-dimensional semantic spaces through the singular value decomposition. [Results] The accuracy rate of the proposed clustering method on the experimental dataset reached 87.3%. [Limitations] The sample data sets need to be expanded. [Conclusions] The proposed model could effectively aggregate names of similar institutions and address the clustering issues of high-dimensional texts.
