A query language for biological networks
MOTIVATION Many areas of modern biology are concerned with the management, storage, visualization, comparison and analysis of networks, but no appropriate query language for such complex data structures yet exists. RESULTS We have designed and implemented the pathway query language (PQL) for querying large protein interaction or pathway databases. PQL is based on a simple graph data model wit...
متن کاملbcnQL: A query language for biochemical networks
This paper proposes a graph data model that can represent information present in Biochemical Networks. The study presented in this paper also proposes a query language, called bcnQL, which empowers users to query entities, interactions, processes and pathways with arbitrary conditions. We then discuss the query-processing techniques, more specifically, the translation of bcnQL queries into G-al...
متن کاملBiQL: A Query Language for Analyzing Information Networks
One of the key steps in data analysis is the exploration of data. For traditional relational data, this process is facilitated by relational database management systems and the aggregates and rankings they can compute. However, for the exploration of graph data, relational databases may not be most practical and scalable. Many tasks related to exploration of information networks involve computa...
متن کاملOntology-Based Natural Language Query Processing for the Biological Domain
This paper describes a natural language query engine that enables users to search for entities, relationships, and events that are extracted from biological literature. The query interpretation is guided by a domain ontology, which provides a mapping between linguistic structures and domain conceptual relations. We focus on the usability of the natural language interface to users who are used t...
متن کاملPQL: a declarative query language over dynamic biological schemata
We introduce the PQL query language (PQL) used in the GeneSeek genetic data integration project. PQL incorporates many features of query languages for semi-structured data. To this we add the ability to express metadata constraints like intended semantics and database curation approach. These constraints guide the dynamic generation of potential query plans. This allows a single query to remain...
