WebSemantic signatures are an analogy to spectral signatures in remote sensing (Janowicz,2012). The underlying idea is 2 that geographic feature types can be characterized by spatial, temporal, and thematic bands … WebWe adopted a novel approach for GIR, focused on handling geographic features and feature types on both queries and documents, generating signatures with multiple geographic concepts as a scope of interest. We experimented new query expansion and text mining strategies, relevance feedback approaches and ranking metrics. Keywords …
WebNov 29, 2007 · Usually, semantic features are implicitly presented in different data sources. In this work, we use three heterogeneous data sources: vector data, geographic ontology, and geographic dictionaries. These repositories usually store topological relations, concepts, and descriptions of geographical objects under certain scenarios. WebOct 1, 2024 · In this way, the semantic information is well preserved in the metric of the embedding space. The whole procedure is shown in Fig. 1(c). We can cast the semantic retrieval task as the problem of searching the most similar vectors to the target vector by utilizing the representation. The main contributions of this work are summarized as …
