MOMIS (Mediator Environment for Multiple Information Sources) (www.dbgroup.unimo.it/Momis) is a framework to perform information extraction and integration from heterogeneous distributed data sources and query management

Local Source Annotation
Gene: a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well as introns between the exons; it is considered a unit of heredity) "genes were formerly called factors"
(Present in WordNet)
Marker: A segment of DNA with an identifiable physical location on a chromosome for any feature that has been genetically mapped
Marker: some conspicuous object used to distinguish or mark something "the buoys were markers for the channel"
(Not present in WordNet)
gene is identified as a BT of allele (as gene is a direct hypernym of allele)
marker is identified as a NT of gene (as genetic marker as been added as a direct hyponym of gene)
Mappings are generated among global and local classes in the cluster (according to a GAV approach)
A Mapping Table (MT) is automatically generated for each global class of a GVV
MOMISidentifies and groups classes that describe the same or semantically related concept in different sources into clusters (global classes)
Source, Reference: a publication (or a passage from a publication that is referred to
(CEREALAB.gene.name) = (gramene.gene.name)
Phenotypic data are divided into six categories chosen among those of major interest for the cereal breeders:
The MOMIS Query Manager is the coordinated set of functions which takes an incoming query (say global query) and performs the following steps:
