Investigating subspace distances in semantic spaces
Zuccon, Guido & Gasco, Enrico (2011) Investigating subspace distances in semantic spaces. In Melucci, Massimo, Mizzaro, Stefano, & Pasi, Gabriella (Eds.) Proceedings of the 2nd Italian Information Retrieval (IIR) Workshop, CEUR Workshop Proceedings, Milan, Italy, pp. 1-4.
Semantic space models of word meaning derived from co-occurrence statistics within a corpus of documents, such as the Hyperspace Analogous to Language (HAL) model, have been proposed in the past. While word similarity can be computed using these models, it is not clear how semantic spaces derived from different sets of documents can be compared. In this paper, we focus on this problem, and we revisit the proposal of using semantic subspace distance measurements . In particular, we outline the research questions that still need to be addressed to investigate and validate these distance measures. Then, we describe our plans for future research.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
