BLOOMS is an ontology alignment system based on the idea of bootstrapping information already present on the LOD cloud. It was developed particularly for Linked Open Data schema alignment.
To obtain more information about BLOOMS, please have a look at our papers Ontology Alignment for Linked Open Data. (Full research paper at ISWC2010:), Contextual Ontology Alignment of LOD with an Upper Ontology: A Case Study with Proton (Full research paper at ESWC2011:), Flexible Bootstrapping-Based Ontology Alignment (poster in Ontology Matching Workshop 2010)  and paper in Workshop on Working with Multiple Biomedical Ontologies, at ICBO 2011 
BLOOMS is an acronym for Bootstrapping-based Linked Open Data Ontology Matching System.
BLOOMS bootstrapping approach utilizes the Wikipedia category hierarchy for aligning ontologies. BLOOMS constructs a forest (i.e., a set of trees) TC (known as BLOOMS forest for C) for each matching candidate class name C, which roughly corresponds to a selection of supercategories of the class name. Comparison of the forests TC and TB for matching candidate classes C and B then yields a decision whether or not (and with which of the candidate relations) C and B should be aligned.
We performed a comprehensive evaluation of BLOOMS using third party datasets and other state-of-the-art systems in ontology matching. More speciﬁcally, BLOOMS has been evaluated in two different ways.
- We examined the ability of BLOOMS to serve as a general purpose ontology matching system, by comparing it with other systems on the Ontology Alignment Evaluation Initiative (OAEI) benchmarks.
- Secondly, we evaluated BLOOMS for the purpose of LOD schema integration and compared it with other systems for ontology matching on LOD schema alignment.
For both the evaluations BLOOMS has been compared with the state of the art tools in ontology mapping.
Systems for Comparison
- RiMOM: RiMOM was the top system in the oriented track of OAEI in terms of f-measure and availability for download.
- AROMA: AROMA ranked second in the 2008 OAEI Benchmark event.
- OMViaUO : OMViaUO utilizes upper level ontologies such as SUMO and DOLCE as semantic bridges in the ontology matching process.
- S-Match: S-Match approach utilizes the semantic information implicitly or explicitly codiﬁed in the labels of nodes and arc for computing the semantic correspondences.
- Alignment-API: Alignment API provides a framework for expressing and sharing ontology alignments. Please note we utilized wordnet based method of Alignment API for matching. Alignment API should be considered as a straw man approach for the purpose of this evaluation.

The selection of parameters for A-API, OMViaUO and AROMA hardly make any difference on this dataset, as this data shows.
