Definition
Text retrieval is concerned with the retrieval of documents in response to user queries. This is achieved by (i) representing documents and queries with indexing features that provide a characterisation of their information content, and (ii) defining a function that uses these representations to perform retrieval. Structured text retrieval introduces a finer-grained retrieval paradigm that supports the representation and subsequent retrieval of the individual document components defined by the document’s logical structure. Aggregation-based structured text retrieval defines (i) the representation of each document component as the aggregation of the representation of its own information content and the representations of information content of its structurally related components, and (ii) retrieval of document components based on these (aggregated) representations.
The aim of aggregation-based approaches is to improve retrieval effectiveness by capturing and exploiting the...
