DBExplorer: Exploratory Search in Databases
A traditional relational database can evaluate complex queries but requires users to precisely express their information need. But users often do not know what information is available in a database, and hence cannot correctly express their information need. Traditional databases do not provide convenient means for users to gain familiarity with the data. In this paper, we study the problem of ...
متن کاملSemantic search among heterogeneous biological databases based on gene ontology.
Semantic search is a key issue in integration of heterogeneous biological databases. In this paper, we present a methodology for implementing semantic search in BioDW, an integrated biological data warehouse. Two tables are presented: the DB2GO table to correlate Gene Ontology (GO) annotated entries from BioDW data sources with GO, and the semantic similarity table to record similarity scores d...
متن کاملExploratory Search in Databases and the Web
The traditional way a user interacts with a database system is through queries. Structured query languages, such as SQL for relational data, XQuery for XML, and SPARQL for RDF data, allow users to submit queries that may precisely capture their information needs, but users need to be familiar with the underlying ontology and data structure and of course the query language itself. Moreover, user...
متن کاملThe freshness of web search engine databases
This study measures the frequency in which search engines update their indices. Therefore, 38 websites that are updated on a daily basis were analysed within a time-span of six weeks. The analysed search engines were Google, Yahoo and MSN. We find that Google performs best overall with the most pages updated on a daily basis, but only MSN is able to update all pages within a time-span of less t...
متن کاملFast Search Methods for Biological Sequence Databases
Biology researchers have a pressing need for data management technologies which will make the storage and retrieval of DNA and protein sequence data accurate and e cient. The volume of data generated by DNA sequencing is already massive and will continue to grow rapidly. Even if the current sequence databases are adequate today, they most assuredly will become inadequate in the future when far ...
