Hybrid Search Ranking for Structured and Unstructured Data
A growing amount of structured data is published on the Web and complements the textual content. Searching the textual content is performed primarily by the means of keyword queries and Information Retrieval methods. Structured data allow database-like queries for retrieval. Since structured and unstructured data occur often as a combination of both, are embedded in each other, or are complemen...
متن کاملEffective Structured Query Formulation for Session Search
In this work, we emphasize on formulating effective structured queries for session search. For a given query, phrase-like text nuggets are identified and formulated into Lemur queries to feed into the Lemur search engine. Nuggets are substrings in qn, similar to phrases but not necessarily as semantically coherent as phrases. We assume that a valid nugget appears frequently in top returned snip...
متن کاملOntology-Driven Query Reformulation in Semantic Search
Semantic search is a research area in which the goal is to understand the users intended meaning of the query. This requires disambiguation of the user query and interpreting the semantics of the query. Semantic search would thus improve the users search experience through more precise result sets. Moreover, ontologies are explicit conceptualizations of domains, defining concepts, their propert...
متن کاملIntegrated Semantic Search on Structured and Unstructured Data in the ADOnIS System
We introduce ADOnIS, an information system which coherently integrates two important, yet mostly disparate data sources, namely structured, tabular data, and unstructured data in terms of publications. The integration is achieved by providing the underlying background knowledge of the domains involved in terms of adequately tailored ontologies. Once the two basic data sources are semantically l...
متن کاملQuery Formulation Method for Structured Information Search Natural
Despite a wide variety of new solutions, structured information search still has only one practical approach – formbased interface. A key limitation of this interface is poor handling of iterative search. While browsing the results users have to memorize all new search constraints, go back to the form, and enter them into the appropriate fields. To overcome this obstacle we created Natural Sear...
